6.1 Initial data

The construction site is located in the city of Berezovsky, Sverdlovsk Region, in a quarter bounded by the streets of Fevralskaya, Builders and the lane. Kirovsky. The site is free from development. There are green spaces on the designated site, which should be preserved as far as possible during construction. Geomorphologically, the site of the designed hotel is located within the floodplain route and the erosion ledge of the Berezovka River. The terrain is slightly hilly, the absolute elevations of the earth's surface vary from 253.0 to 255.0.

According to the data of the present surveys to the depth of illumination of the geological section up to 12 m, underground waters in the survey area are not met. Due to the fact that the site is in the area of ​ ​ the mine drainage, the level of groundwater is lowered to a significant depth.

The geologolithological structure of the site is represented by the following varieties of soils. Note: Soil name as per GOST 25100-95:

1st layer - bulk soil. At the survey site, it is ubiquitous, composed of wood-crushed stone, loamy material with an admixture of construction debris, scrap metal. Bulk soils were formed during the planning of the site and the construction process.

The 2nd layer of loams is eluvial, brown, mainly hard, heavy. Distributed almost everywhere.

The 3rd layer is eluvial loam, brown in color, hard, with interlayers and lenses of semi-solid, heavy, dry, highly porous areas.

The 4th layer is eluvial loam, solid, with layers of semi-solid, weakly structural. Distributed almost everywhere.

The 5th layer is rock soil of shale, strong-warm, from reduced to low strength. Distributed almost everywhere.

6.4.5 Description of works.

According to the engineering and geological survey of the site, we have a calm relief, absolute elevations vary from 253.00 to 255.00. Water lowering measures are carried out by NCS2 pumps. The development is carried out by a group of single-bucket excavators EO3322 of the "reverse shovel" type with a bucket capacity of 0.65m3 and bulldozers with a capacity of up to 132kW. Soil intended for backfilling, sinuses of foundations is developed in the dump within the range of the working element, but it is necessary to provide free access to the foundation pit for further installation work, the remaining soil is loaded into dump trucks and taken outside the city limits in a radius of up to 20 km.

Site development procedure: Preparatory period works - site preparation works are performed.

Works of the main period - the development of the hotel pit, work on the construction of the underground part of the hotel, work on the construction of the above-ground part of the hotel, finishing work

7.4.6 Construction of the basement of the hotel.

Foundation cushions are laid with KB403 tower crane, foundation blocks are mounted with the same crane on 50 grade mortar, local seals are made with B15 concrete. It is mandatory to make dressing of foundation blocks. Perform waterproofing works by means of the CO122A installation.

Arrangement of inputs and outputs of underground utilities.

Backfilling of foundations along the perimeter of the building shall be performed after laying of slabs of the first floor slab. Backfilling of pits and trenches of foundations is carried out with layer-by-layer combined compaction of soil, directly near the foundations by electric ramming for 0.4m; in the rest of the volume of backfilling with mounted hydraulic hammer on the basis of the same excavators. Compaction of the whole platform is performed by cam rollers. Backfilling and layout of the site and the bottom of the pit are carried out by bulldozers.

6.4.7 Construction of the above-ground part of the hotel.

Brickwork of walls is done manually. Bricks are laid on cement sand mortar. Thickness of solution in horizontal seams -

10-15 mm, vertical - 8.. 15 mm. It is necessary to cover the seams in adjacent rows of masonry by dressing. Brick and mortar are supplied to the bricklayer's workplace using a crane in containers.

Brickwork is carried out in compliance with technological rules: watering bricks, uniformity of masonry construction along the entire front of work, horizontal rows, vertical corners and walls.

Lining of external walls with insulation is carried out in parallel with lifting of walls.

Window and door openings in the walls are covered by reinforced concrete bridges using crane KB - 403.

Floor-by-floor installation of slab structures, stairway and closure of monolithic sections in accordance with the design .

6.4.8 Hotel roof arrangement.

Before steam insulation, remove water, ice and snow from the roof base. For removal of water use the CO106 A installation (power of 2.2 kW, the drive electric, the weight of 60 kg, capacity of a tank of 20 l, performance of 20 l/min), drying of the basis, removal of frost is carried out by CO159 installation (performance of 80 sq.m/h, the power of 3.4 kW, the drive electric weight of 160 kg).

Waterproofing laying, then cement - sand bracing with compaction by hand boat. Cement-sand bracing is laid in strips 4 m wide. Laying of tile insulation is carried out manually. Then another layer of cement-cloth brace with compaction is laid and compacted.

Piece materials - rolls, insulation plates, sand, gravel are supplied to the roof using replaceable containers or crates with crane

KB- 403, bracing solution, bitumen mastic with the same crane.

Bicroelast is glued with CO99A on bitumen mastic. The transverse overlap of the panels is 70 mm, the longitudinal overlap is 100 mm. To cut the base, a CO122A machine is used, which receives bitumen mastic and applies it to the roof.

For heating, hashing and supply of mastic on a roof we use the CO100A installation (giving of pump 6m3/ch, the drive electric, weight of 3500 kg).

Horizontal movement of materials along the roof is carried out by manual two-wheeled trolleys. The gravel is leveled manually by a layer of bitumen mastic and compacted by a hand roller.

6.4.10 Monolithic floor arrangement.

Disassembly formwork is used, to reduce the adhesion of formwork to concrete, the front surface of the installed formwork is lubricated with lime milk. The accuracy of the formwork installation shall be checked taking into account permissible deviations (+ 5 mm) from normal dimensions.

Reinforcement is delivered to the site in windings and bars, on a specially designated site the rods are straightened and cut. Grids are welded by electric welding. Reinforcement elements are laid in the formwork using a caterpillar crane. Before the concrete mixture is laid in the formwork, the correctness of installation of reinforcement, reliability of attachment of all elements must be checked.

First of all, the main and secondary beams are concreted, only after the concrete strength is gained, the slab is concreted. Concrete mixture is laid in layers and compacted with vibrator IV116, concrete mixture is supplied to place of installation by concrete pump. Freshly laid concrete, first of all, is covered from rain and sunlight (covered with tarpaulin) and systematically watered for 7 days. Concrete fracturing only after reaching strength of not less than 70% of design. Safety posts shall be located not more than 3 m from supports and from each other. After the formwork is removed, clean the small shells on the concrete surface with wire brushes, rinse with a jet of water, and wipe with a fatty solution. To clear away large sinks and cavities on all depth, about removal with removal of weak concrete, wash with water, and close up rigid concrete mix a torkretirovaniye.
