1.2 Information on engineering, hydrogeological conditions of the construction area

1.2.1 Climatic conditions

According to climatic conditions, B. Sochi belongs to the IV-B zone, allocated to the southern region of the Black Sea province. The main features of the climate are hot, humid summers, warm winters and autumn, long spring. The winter period is characterized by periodic instability associated with the invasion of cold air masses. In the coastal zone of B. Sochi, the duration of the frost-free period is 289310 days. The average annual air temperature is + 14.1 ° C, the absolute maximum is + 38 ° C, the annual amplitudes of the temperature variation are 1819 °. In valley lowlands, decreases to 20 ° are possible. The average relative humidity is 6870%, the amount of precipitation falling for the year is 1605 mm, in September-April 1279 mm falls, in May-August - 326 mm, the number of days with snow cover reaches 9, the snow cover capacity usually does not exceed 1030 cm. The average wind speeds of local circulation do not exceed 1.9 m/s. in summer and 2.8 m/s. - in winter. The maximum maximum wind speeds for the Tuapse-Sochi region are taken to be 25 m/s, the strongest winds are southeast. Fog on the coast occurs mainly in winter and spring, the number of days with them reaches 58. Seismicity of the construction site - 8 points.

1.2.2 Geomorphological conditions

Geomorphologically, the construction site is the remains of an ancient Black Sea terrace composed of light brownish-yellow clays, at the base of which lies the basal horizon of pebbles. The basement of the terrace is formed by the blurred surface of the argillites of the Sochi retinue of the lower Oligocene.

1.2.3 Geological structure of the site

The geological structure of the site is represented by indigenous deposits of the Paleogene and Quaternary formations of various genesis.

The indigenous base of the slope of the Sochi River Valley is composed of rocks of the Sochi retinue of the Oligocene - argillites gray, layered, with thin sandstone layers.

Quaternary deposits are represented by soils of various genesis: these are bulk man-made soils, deluvial-belt clays with landslide breccia of argillites, marine pebble deposits, elyuvium of native rocks.

According to surveys (including previous years), the following lithologenetic groups are identified in the geological structure of the site from top to bottom along the section to a depth of 32.0 m:

Class of man-made dispersed soils.

Group of disconnected natural displaced bulk formations. Layer 1 - Dispersed associated naturally displaced bulk clay non-swelling soils - brown clay, brownish - gray to gray, loose, with fragments of argillite, sandstone, with a large amount of construction debris (concrete, brick, household garbage). The thickness of bulk soils is 0.5-1.5 m, rarely increasing near underground structures and communications to 2-3 m. They are widespread almost everywhere.

Class of natural dispersed soils

B. Group of connected sedimentary polymineral clay soils. Layer 2 - Dispersed natural sedimentary deluvial-bearing soils - yellow-brown clay, gray spots, semi-solid, dense, swelling, with an admixture of sandy material, with pebbles (up to 1015%), with fragments of weathered argillite and sandstone (up to 1525% by layer). The thickness of the soils of layer 2 is on the surface of the Ancient Sea terrace 1112 m, decreasing higher along the slope (within the indigenous ledge) to 2-5 m. The soils of the layer are developed everywhere from the surface of the earth or under the embankment.

B. Group of incoherent sedimentary coarse soil.

Layer 3 - Dispersed incoherent natural ancient Roman pebble soils of the Karagant terrace - pebbles of sedimentary and metamorphic rocks, large and medium, gravel with sandy-clay aggregate up to 2025%, with large boulders of cooked sandstone. Pebbles have a power of 2-4 m.

B. Group of connected sedimentary polymineral clay soils.

Layer 4 - Dispersed coherent natural sedimentary eluvial soils - argillite brown to grayish-brown, wormless and obscure, weathered to hard clay and debris, weak, highly fractured. The thickness of the eluvium is marked in the roof of the indigenous massif. The thickness of the soils of layer 4 varies within 0.52.0 m. Soils of layer 4 are marked in the western part of the area under consideration .

Layer 5 - Dispersed incoherent sedimentary softening, waterproof, layered eluvial soils - argillite brownish-gray to gray, layered in the massif, iron-lined by steep cracks and spraying, with layers of sandstone brown, cracked. The soil of layer 5 is marked by local distribution in the western part of the area under consideration, in the roof of the bedrock, its thickness varies from 0.5-1.0 to 1-5 m. The soil is a transitional type of argillite from weathered differences to the bedrock.

Class of natural rock soils

G. Group of semi-rock soils.

Layer 6 - Semi-rock sedimentary low - low strength softened, low water permeable, layered, fractured soils - argillite gray, layered, at separate intervals broken, leafy, with vertical microcracks, with thin (2-7 cm) sandstone layers. During boreholes penetration in the core stratum, interlayers of brecciated, sheet argillite, sandstone stratum and calcite stratum are marked. The fall of rock formations is noted in azimuths of 260330 °, falling angles of 515 °.

1.2.4Hydrogeological conditions

Hydrogeological conditions of the site are characterized by the distribution of:

a) permanent aquifer confined to terrace sediments;

b) crack waters marked in the bedrock at depths more than 1220 m from their roof;

c) groundwater of the headwaters type.

The permanent groundwater horizon is confined to the lower reaches of the ancient Roman pebble terrace, which serves as a good natural groundwater collector - it discharges groundwater from the lower part of the slope. The groundwater mirror of this horizon is marked at abs. Elevations 23.0-24.0 m. Dense differences in the bedrock serve as a watershed for this horizon. The groundwater of the permanent horizon is fed mainly due to atmospheric precipitation and due to groundwater coming from the upper sections of the slope.

The groundwater horizon of the fractured type has a limited distribution, groundwater of this type is marked in eluvium or confined to zones of increased fracture in native rocks.

The headwater appears in the autumn-winter period in clay soils almost everywhere at depths of 3-4 m about 0.8-1.2 m. The headland is fed both due to atmospheric precipitation and due to leaks of domestic waters from dilapidated water-carrying communications.

The headwaters and groundwaters of ancient Roman pebble deposits are non-aggressive to concrete on all types of cement. Water - medium of fractured waters is weakly aggressive to concrete of W4 grade by waterproofness (SNiP 2.03.1185, vol. 6).

1.2.5 Physical and geological processes and phenomena

Unfavorable physical and geological features of the site include the fact that the designed construction is planned on an old-earth slope. The survey site is located in the contour of the ancient landslide G655 with a length of 300 m, a width of 425 m, a capacity of 7.0 m. The basis for the displacement of this landslide by SKGEC geologists is designated ul. Krasnoarmeyskaya. Landslide activity in the isolated circuit has not been manifested for more than 30 years.

1.3 Solutions and Key Indicators

according to the master plan and improvement of the site

The land plot provided for the design and construction of a residential building is located in the reconstruction zone of the central part of the city of Sochi, Krasnodar Territory.

The triangular section is bounded by the existing urban, multi-storey building and borders:

from the north - with 2-5 storey residential buildings;

from the east - bounded by the street. Krasnoarmeyskaya;

from the southwest - bounded by the street. Vinogradnaya, on the opposite side of which begins the territory of the Riviera park.

The relief of the site is flat, with a significant difference in elevation from 40.0 m to 18.0 m in the north direction and a sharp difference in elevations from 25.0 m to 12.6 m in the area adjacent to ul. Krasnoarmeyskaya.

Currently, the territory is built up with buildings and structures of the former brewery to be demolished. Communications existing on the site are partially subject to transfer, partially subject to complete dismantling.

Objects existing on the territory to be developed, as well as on residential buildings on plots adjacent to the quarter under consideration, are not included in the list of historical and cultural monuments.

The master plan is developed in accordance with the layout limitation scheme. Planning decisions of the master plan are made taking into account the specifics of the existing topography of the territory, when designing the vertical layout of cutting and filling of soil, they are provided in a minimum amount in order to preserve the existing topography in order to avoid the appearance of landslide processes after the development of the construction site.

The designed complex consists of single-section buildings of high storey freely arranged along the perimeter of the triangular section - a layout predetermined by the configuration of the section. The buildings are located along Vinogradnaya Street and in the northeastern part of the territory on the street. Krasnoarmeyskaya.

The vertical layout is solved taking into account the existing terrain, stormwater removal is carried out along driveways and platforms to lowered places.

The construction area is being improved. The main entrances to the complex are decided from ul. Vinogradnaya and st. Krasnoarmeyskaya. The driveways and turning platforms are supposed to be made with a two-layer asphalt concrete surface framed with on-board concrete stone BR 100.30.18 .

Pavements, areas in front of entrances to residential buildings are provided with concrete pavement. Paving of sidewalks and platforms in front of the entrances to public buildings uses paving tiles made of colored concrete .

The territory, free from development and hard coatings, is sown by lawn grass, landscaped by planting decorative trees of valuable species and shrubs.

The project provides for measures to ensure the life of low-mobility population groups.

1.4 Substantiation of architectural and construction solution of residential building No. 1

The peculiar configuration of the site allocated for the construction of a residential complex - a rectangular triangle, predetermined the basic principle of layout: four towers located along ul. Vinogradnaya - one-section 16-story buildings .

One-section 16-story residential building, pos. 3, provides for 80 apartments. The first two floors of the building are non-residential. They are supposed to accommodate offices and necessary for the normal service of residents of the complex of the consumer service enterprise (reception points of the laundry, dry cleaning, small ateliers for the repair of household appliances).

The layout of the interior of the residential part of the house meets the requirements of the standards and the customer's task. On each of the typical floors there are at least five apartments (one three-room, two two-room, two one-room). Apartments are provided with convenient layout, with a full set of internal equipment, enlarged glazed loggias. The building is equipped with two elevators: cargo - 630 kg, and passenger - 400 kg.

In the basements and technical floors there are engineering equipment of a residential building, including control frames, communication input units, electric switchboard, ventilation units that create air overpressure in corridors and elevator shafts and halls, ventilation installations of smoke removal.

The building is supposed to be monolithic. The external walls are multilayer, made of reinforced concrete, lined with fibropene concrete heat insulation plates. The basement is finished with stone plaster with rustication for limestone, granite.

Decorative elements of the facade of the main entrance should be made according to sketches agreed with the authors of the project and the main architect of the city.

1.5 Protection of historical and cultural monuments

Due to the absence in the territory of construction and adjacent in the northern part of residential development of objects classified as historical and cultural monuments, measures for the preservation of monuments or their restoration, this feasibility study does not provide.

Installation and disassembly by crane of large-shield wood-metal formwork of walls. The formwork of one side of the wall is installed to the entire height of the wall and is fixed by braces and screw struts. The formwork of the second side of the wall is installed after installation of the wall reinforcement. During installation of the panels of the second side of the formwork, fights, temporary spacers and bolt ties are installed. Installation and disassembly of formwork is performed from scaffolding.

Installation of slab formwork located at a height of up to 5.5 m from the lower slab is carried out without preliminary arrangement of scaffolding. Panels of floor formwork are laid on walls, after which inventory sliding posts are brought under them, which are extended by the required length. Precise installation of the formwork boards is achieved by moving the jacks under the posts. Formwork of floors is installed from portable ladders.

The walls are reinforced together with the wall formwork. The reinforcement is supplied by a crane, tied into spatial frames.

Reinforcement of slabs is performed after arrangement of slab formwork. Reinforcement is supplied by a crane, tied into grids, set on concrete gaskets, fixed and adjusted.

4.4.2 Concreting of walls and floors.

To deliver the concrete mixture, SB92 concrete mixers with a drum capacity of 5 m3 are used. The required number of machines is considered in the application. The concrete mixture is supplied to the concreting site using a tower crane in buckets with a capacity of 1.5 m3.

Walls in disassembling formwork are concreted without interruption, with sections no more than 2 m high. The concrete mixture is compacted with depth vibrators.

When concreting walls from above, the lower part of the formwork is first filled to a height of 1020 cm with cement mortar of the composition 1: 2-1: 3 in order to avoid the formation of porous concrete in this part of the wall with a cluster of coarse aggregate.

4.4.3 Concrete holding and formwork wrapping.

The decompression is started after the concrete has achieved the required strength. Since the concrete hardening rate mainly depends on the ambient air temperature, the time after which the decontamination is carried out is set according to SNiP:

for slabs with a span of up to 3 m, 70% of the standard strength at a concrete temperature of 20 ° C is achieved at 7 days from the day of concreting.

When removing floor posts supporting the formwork of concreted floors of multi-storey buildings, they are guided by the following rules:

It is not allowed to remove the slab formwork posts located directly under the concreted slab,

the formwork post of the next underlying slab can be removed only partially, while under all beams with a span of 4 m or more, safety posts located one from the other at a distance of not more than 5 m are left;

formwork posts of the remaining underlying floors can be removed completely if the strength of these floors has reached the design level.

4.6.1 Methods and methods of labor of workers on performance of work processes and operations.

Works on installation of wall formwork and floors with simultaneous installation of reinforcement are performed in the following sequence.

Construction locksmith M 1-2 and S-3 performs marking of places of installation of formwork boards by layout axes. Locksmith M-4 and M-5 with spraying pistols apply emulsion layer on working surfaces of formwork shields. M-4-5 sling the shield for two mounting loops. Moving to a safe distance, the M-4 gives the command to the crane driver to lift the shield. M-1-2-3 receives the fed shield and orients it over the installation site. At the command of M1, the crane driver lowers the shield, and the M-1-3 locksmith sets it, combining the markup risks with the shield. After upset, the shield is temporarily fixed with braces and strubcins.

After installation of one of the sides of the formwork, the internal reinforcement of the walls is installed.

Installation of reinforcement frames is performed by a link of workers performing formwork installation.

M-4-5 reinforcement mesh is slung in accordance with the specification. Moving to a safe distance, the M-4 gives the command to the crane driver to lift. M-1-3 receive the grid and orient it to the installation site. After reconciliation and installation, the reinforcement mesh is welded to the reinforcement outlets and temporarily fixed. After that, the formwork board of the second side of the wall is installed. Shields are bolted, temporary spacers are installed. Mechanics

M-1-2 final reconciliation of installed formwork is performed using levels and plumbs. After that final attachment of formwork with braces, fights, struts and braces is performed.

The arrangement of the floor formwork begins after the installation of the formwork of all the walls of the room.

M-1-3 locksmiths are laid according to working drawings and diagrams. Extensible inventory girders are installed on the heads of the struts, which are attached to the heads of the struts with pressure strips, and in the top to the formwork of the floor slabs, the latter consists of metal shields connected to the panel using runs-bumps and spring vanes. Along the perimeter of the plate, frieze boards are installed to facilitate further unraveling. The final, accurate installation of the floor formwork is achieved by moving the jacks under the posts.

M-4-5 slings the reinforcement slabs and gives a signal to the crane driver for lifting.

M-1-3 concrete gaskets are brought up and laid with their fixing. Fed mesh is installed by means of crane into formwork. After that correctness of installation is verified according to drawings of concrete structures.

Concrete work is carried out by a link of two people: concrete workers of 4 and 2 categories.

The concrete mixture is delivered to the construction site by dump trucks and unloaded on a specially designated site directly to the taverns.

Badyas are fed by crane directly to the place of laying. Concrete workers M13, 14 before concrete is supplied, a receiving funnel is installed at the place of laying, the walls are concreted, bringing the concrete mixture from above through the funnels continuously to the entire height of the wall. The concrete mixture is laid in layers equal to 0.8-0.85 of the length of the working part of the vibrator tip. Concreting of slabs, monolithically connected to walls, begins not earlier than 1-2 hours after concreting of walls, due to the need for initial settlement of laid concrete mixture.

Before concreting, concreters M13, 14 install beacon racks, which are installed on the formwork in rows after 22.5 m and attached to bosses located on the formwork. The upper plane of the rack is located at the level of the top of the plate. After the racks and bosses are removed, the remaining recesses in the slab are sealed with concrete. The concrete mixture in the slabs is compacted with vibrobrus. The worker sets the vibrators to the initial position between the beacon racks, turns on the engine and together moves the vibrator to the end of the grip at a speed of 0.20.4 m/s. As concrete is concreted, concrete is shaken slightly with metal hooks, ensuring that a protective layer of concrete of the necessary thickness is formed under the reinforcement.

The expansion of wall structures and floors is carried out by link No. 5.

In the formwork of the walls, locksmiths M2527 first remove the tightening bolts, then horizontal fights from top to bottom. Then the shields are torn from the body of concrete. Then they are slung and removed with a crane.

In the floor formwork, the bars bordering the runs are removed, frieze boards are removed and, using jacks, the posts are smoothly lowered, the bottoms are torn off. Then struts between struts are removed and struts themselves are removed.

The complex of finishing works is divided into 4 sequential cycles;

1 - plaster works;

2 - installation of articles subject to painting treatment;

3 - preparation for painting;

4 - work on the arrangement of floors.

All finishing works are carried out from suspended scaffolds - inventory-type columns adapted for movement through standard door openings.

The solution for plaster works brought to the construction site is unloaded to the receiving hopper of the solution receiving unit. The solution is then fed to the plaster workstations by a plaster station.

For painting works, a mobile painting station is used, from which compositions for whitening ceilings and walls are supplied to the workplace through hoses. Quality of work is checked by templates and visually.

5.4 Construction plan

The construction plan was developed for the period of construction of enclosing structures of the building. The purpose of the construction plan is to organize the construction farm on the site, which ensures the creation of the necessary working and rest conditions for workers, for mechanization of work, acceptance, storage. Laying of materials, structures, provision of works with water and energy resources.

The construction plan is part of the integrated construction documentation and is developed in accordance with the accepted work technology and construction deadlines established by the schedule.

During the development of the construction plan, the requirements of SNiP 3-4-80 "Safety in construction" are provided. In order to create favorable living conditions and reduce the cost of building temporary buildings and structures, they are located in areas not intended for development until the end of construction.

To avoid intermediate bulk unloading, all open warehouses are located in the crane area. Brick shall be stored on pallets and containers. For the storage of timber and metal elements, window and door bindings, canopies are provided.

Temporary buildings and structures by the number and composition of areas are determined by calculation (see Table). Crane and hazardous areas are indicated on the construction plan, warning signs are installed that limit the movement of people and cars on the construction site.

Roads on the construction site are designed according to the condition of ensuring the free passage of vehicles: permanent roads with a width of 6 m, temporary roads with a width of 3.5m, a turning radius of 12 m. At the turns, widening by 1 m is provided. Road slopes are linked to the terrain.

Water supply and sewerage, designed based on the conditions for providing industrial household and fire-fighting construction needs in water. The distance between hydrants does not exceed 150 m, they are located no further than 2 m from the road, 2 hydrants are provided.

To provide electricity from the existing network, an FTC unit with a capacity of 180 to W is provided. In order to ensure reliable power supply, an annular electrical support system has been designed, air lines are provided along the driveways, which makes it possible to use poles for outdoor lighting fixtures and facilitates operating conditions. In the areas of the site where the crane operates, cable laying is provided.

The entire territory of the construction site is fenced with a vertical fence of wooden shields. At the places of entry and exit there is a gate, along the entire perimeter of the construction site there is a lighting network with spotlights.
