The rest of the work is carried out by conventional methods and do not require special explanations.

Power supply

Power supply networks are laid together with communication cables (in one trench)

The trenches include preparatory works, arrangement of trenches, delivery of drums with cable to the place of work, cable rolling and laying in, cable protection from mechanical damage and backfilling of trenches. During the preparatory work, the necessary amount of brick, sand or sifted land is delivered to the route, as well as steel or asbestos cement pipes with an internal diameter of at least 100 mm for the arrangement of cable line crossings under railway tracks, roadways and various obstacles located on the cable line route.

When the cable route crosses footpaths, transition bridges with barriers shall be installed in the appropriate places, delivered in advance to the route. It is possible to start digging trenches after the absence of underground structures, pipe connections or other cables on the route or in dangerous proximity to it is checked as planned or using hole holes. To do this, the location of underground structures is checked according to the plan, and in the absence of the plan, test holes with a width of 350 mm are made across the intended route; pits must be dug with great care so as not to damage cables, pipes or other structures that may be in the ground. Trenches with a large length are arranged with special rotary trenches with digging, and more often with conventional excavating machines or excavators.

Trenches with a small length and passing under paved sidewalks, as well as trenches laid in wall areas where it is impossible to use mechanisms, are dug manually using a scrap and a shovel.

The depth of the trench is accepted according to the design, and the width is such that the distance between several parallel cables laid in it with a voltage of 10 kV is at least 100 mm, and from the wall of the trench to the nearest extreme cable is at least 50 mm. The cable laying depth can be reduced to 0.5 m in sections up to 5 m long when the cable is introduced into the building, as well as at their intersection with underground structures, provided that the cable is protected from mechanical damage by laying it in asbestos cement pipes.

In places of future location of cable distribution couplings, trenches are expanded to form pits. Pits for one cable coupling up to 10kV shall be 1.5m deep and 2.5m long. For each next row of the coupling to be laid, the pit width shall be increased by 350mm.

Excavated cobblestones, pieces of asphalt and concrete are laid on one side of the trench or pit at a distance of at least 1 m from their brow to ensure the free movement of workers along the route.

Cables are delivered to the place of laying in drums on special cable conveyors or on cars equipped with a device for loading, transporting and unloading the drum with cable. Discharge the drums with the cable carefully so as not to damage it and not cause injury to the workers.

It is strictly forbidden to drop drums with cable from cars or from cable conveyors. The cable should be unloaded as close as possible to the rolling point, but so that it does not interfere with the movement of workers, does not pose a threat of falling into the trench and is conveniently located for rolling.

Cable delivered to the place of laying is rolled out of drums by means of moving transport, winch on rollers, manually on rollers or without rollers. When rolling a cable from a moving vehicle from a car or a cable transporter, two workers manually rotate the drum, winding the cable from it, and the other two workers receive and put the cable in a trench. The cable is wound off the drum from above and not from below. Rolling is performed at vehicle or towed conveyor speed not exceeding 2.5 km/h. When rolling from a drum located on the ground, the latter must be raised above the ground by a 200 of 250 mm using a steel shaft and two cable jacks. Wooden boards with a thickness of at least 50 mm, bricks or reinforced concrete slabs are laid under the jacks.

Prior to the cable rolling, linear and angular rolling rollers are installed in the trench: linear rollers are installed on straight sections of the trench every 2 m, and angular rollers are installed in places of bends and turns of the trench.

When rolling the cable manually, workers put it on their shoulders and slowly move along the trench or along its bottom. The cable located on the shoulders of the workers should not have large bends. The load on each worker involved in manual cable rolling shall not exceed 35 kg. The cable must be on the same arm of each worker carrying the cable. It is necessary to lower the cable from the shoulders simultaneously and in two steps: first to the level of the lowered hand, and then to the ground. It is strictly forbidden to drop the cable on the ground to avoid accidents or damage to the cable. In case of insufficient number of workers required for normal rolling of the cable designed for voltage up to 1kV and at ambient air temperature above 0 ° C, loop rolling is used. To this end, the drum with cable is installed not at the beginning of the trench, but at the middle of its length: half of the cable from the drum is wound from above to one side, and the remaining half is wound from below the drum to the other side with a loop brought through the drum.

Communication networks.

Laying of unarmored optical cables in the occupied cable sewer channel by electrical cables shall be provided in a pre-laid polyethylene pipe.

In headers the cables shall be arranged as follows:

- with a two-row arrangement, wire broadcast cables can be laid on one side or on the other side of the passage. At the same time, on one side of the passage, wire broadcasting cables should be laid from above, below the communication cables and under them thermal conductors. On the other side of the passage - power cables from above, wire broadcast communication cables below, then communication cables and water pipes below them ;

- with a single-row arrangement, power cables must be laid on top, wire broadcasting cables below them, communication cables below, even lower water and heat pipelines .

In case of parallel laying in headers of communication cables and power cables, communication cables shall be located 20 cm below power cables.

When laying in manifolds of communication cables, the latter shall be located not less than 10 cm above pipes of water supply, heating system and other pipelines.

Heating system.

The heating system is laid in a channel-free manner, and in impassable channels. Piping installation shall be performed by specialized installation organizations, at the same time installation technology shall ensure high operational reliability of pipelines operation.

Earthworks and foundation works shall be performed in accordance with the requirements of SNII876, SNiP 3.02.0183.

Self-propelled boom cranes are used for installation of heating system from steel pipes. If they cannot be used according to the conditions of work, then manual devices such as tripod and portals are used.

The pipes along the trench should be placed at its edge so that they do not interfere with the mechanisms working on the pipeline laying. Pipes and mechanisms shall be arranged rationally so that from each parking of the mechanism it is possible to lower the largest number of pipes into the trench.

In order to avoid unnecessary displacements during piping installation, pipes, fittings and shaped parts should be laid out along the trench, taking into account their location along the pipeline line in accordance with the design.

For mounting and hanging of single pipes and lashes to the load hook of the mounting crane or lifting device, various gripping devices are used, which must ensure the pipe is firmly fixed. The most common of these are captures like towel rice 3.

Total rated power of electric motors of construction machines

Water consumption for household needs

Q2 = 0.01 + 0.07 = 0.08 l/s.

Calculation of fire-fighting water flow rate

The water flow rate for external fire extinguishing is taken on the basis of the three-hour duration of extinguishing one fire and ensuring the calculated water flow rate for these purposes at the peak water flow rate for production and household needs.

When calculating water consumption, it should be taken into account that the number of simultaneous fires is accepted at the construction site up to 150 hectares - 1 fire, St. 150 hectares - 2 fires.

The size of the territory is taken equal to 1 ha.

Estimated number of fires f = 1.

The water flow rate for fire extinguishing of the building is 2.5 l/s from each jet of the internal fire crane.

Number of internal fire cranes used for fire fighting n = 1;

Water flow rate for building fire extinguishing, Q31 = n * q31 = 1 * 2.5 = 2.50 l/s.

The area of the building for calculating fire fighting is 2.35 thousand m2 .

Fire resistance rating of building II.

Fire hazard category G.

From the prevailing conditions on the construction site, household ones are not divided into dressing rooms, washrooms, etc. - we take the required area for administrative and household buildings as the total for all these premises.

Based on the area of one house - 18 m2, we accept the total number of houses 2 pcs.

To heat mobile inventory buildings, use factory-made electric heaters.

1.19 Description of design solutions and measures for environmental protection during construction.

The incorrect organization of the construction site and the operation of construction equipment, as well as their structural shortcomings, can have a negative impact on the environment, which can manifest itself in the following:

pollution of water bodies and surrounding areas by construction waste, garbage, sewage and toxic substances;

in the increased carbon monoxide content in the exhaust gases of the aircraft due to incomplete combustion of the fuel;

- in splicing or sewing of working fluid and lubricants when filling machines or changing oils to winter and summer grades.

The completeness of ICE combustion and therefore the amount of carbon monoxide contained in the exhaust gases depends on a number of reasons:

- fuel quality;

- condition, engine; -qualification of the driver.

It should be remembered that the combustion conditions of fuel in engines in the cold season are deteriorating - a large amount of it is not completely burned, which is accompanied by increased carbon monoxide emissions. In addition, at low temperatures, it is difficult to start ICE after interchangeable storage. Fuel and lubricants cause great harm if for various reasons they fall on the ground, the vegetation layer, into the water. Residues of fuel and oils, wiping materials left after operation can cause fire as a result of spontaneous combustion or ignition of the fire.

During construction and installation works it is necessary to comply with environmental protection requirements set forth in SNiP 3.01.0185, SNiP 3.02.0187 and SNiP 3-8-76. It is also recommended to take into account the provisions of the Water Code of the Russian Federation, the Rules for the Protection of Surface Waters from Sewage Pollution, approved by the Ministry of Water Transport, the Ministry of Fisheries, and the Ministry of Health of the USSR.

When developing a project for the execution of work, the general contracting construction organization on the basis of the above documents, taking into account the project for the construction organization, should develop natural protection measures, in which it is necessary to reflect:

- Measures for the protection and rational use of land;

- Measures to protect trees and vegetation;

- air pool protection and noise control measures;

- Measures to protect water resources.

Land conservation and management activities should include:

maximum reduction in the size of the construction site for construction and installation works;

- preservation of removed topsoil for its subsequent restoration;

application of special devices for receiving mortars and concrete mixtures;

measures to ensure storage, temporary storage of fuel and lubricants and maintenance of construction machines and mechanisms at special sites equipped with an organized storm water collection system (device along the perimeter of temporary storm sewage sites) with diversion to local temporary treatment facilities or storage tanks with their subsequent removal by special transport from the construction area;

- execution of measures preventing fuel and lubricants from getting to the ground during filling of construction machines and mechanisms at the workplace (filling with gas stations, use of inventory pallets, etc.);

- cleanliness of containers in case of manual filling of construction machines and mechanisms;

- provision of overflow of replaceable oils and working fluids of construction equipment into specially prepared tanks with subsequent sending for regeneration;

- cleaning of building debris

Measures to protect plantations and vegetation should include:

- fencing of wood plantings on the construction site, installation of warning signs in places of movement of construction equipment and transport;

- timely improvement of the territory with restoration of fertile soil;

- fire safety.

Air basin protection measures should include measures to prevent the release of substances harmful to humans and the environment. To this end, provision should be made for:

- adjustment of fuel equipment of internal combustion engines and installation of neutralizers for oxidation of incomplete combustion products on them;

- application for technical needs of electric power instead of solid and liquid fuel;

Noise control should be aimed at ensuring normal working and living conditions of workers and include:

- use of construction equipment with electric and hydraulic drive as much as possible;

use of silencers for engines;

compliance with technological discipline;

improving the quality of access and on-site roads;

use of containers for transportation of construction goods.

Measures to protect water resources should exclude the possibility of discharging building waste, fuel and lubricants, wastewater and toxic substances into the water. To this end, provision should be made for:

- Equipment of the construction site with temporary sewage systems ensuring the removal of industrial, household and rain wastewater to local temporary treatment facilities or storage tanks with their subsequent removal by special transport from the construction area;

- organization of incoming control of building structures and materials for conformity of the quality of the applied materials to the design in terms of the content of toxic substances dangerous to the plant and animal world.
