Information about the functional purpose of the object

The operation of the snow collection point is based on the method of storing snow, followed by its natural melting and discharge of melt water into sewer networks. Snow collected from city streets is delivered by road to the site of the snow collection point, where it is unloaded and stored. The base of the platform has a waterproof coating. The site is surrounded by embankment. Dump trucks enter the territory of the site through a gate 8 m wide, then at the entrance past the checkpoint they enter the site. A rack for an automated vehicle accounting system is installed next to the gate. During the work of the snow collection point in winter, the gates at the entrance are open around the clock. Closed during summer. The snow coming for disposal at the snow collection site is significantly polluted with debris, a large amount of sand applied to the roads accumulates in the snow. After the end of the winter period, it is necessary to carry out activities to clean up the site from debris and remove waste to the landfill. After clearing of debris, the site should be "mothballed". The possibility of using the site in the summer for other purposes (for example, for parking cars or trucks) must be decided by the Customer together with the operating organizations. Snow storage is carried out with the formation of a snow dump in the form of a prism 8 m high using a bulldozer. The work area is divided into two parts - the unloading area and the planning area. When dump trucks move along the site, it is prohibited for vehicles to enter the gratings covering the trays. In the unloading zone, the snow mass is unloaded from dump trucks, in the planning zone, a bulldozer operates, moving the unloaded snow to the top of the dump, bringing the height of the dump to 8 m. in free space. Filling the site with snow begins from the side of the site farthest from the entrance, with a gradual approach to the entrance as the capacity of the site is filled. The height of the dump reaches 8 m, the steepness of the slopes is 1:1.5 The slope in the bulldozer operation area when moving snow is 1:3.

Space planning solutions

The task of the project was to design an object in the existing planning and vertical marks for receiving and utilizing snow masses in the winter season. The boundaries of the territory are adopted in accordance with the town-planning plan of the land plot. The scheme of the planning organization of the land plot was developed in accordance with the design assignment on a topographic survey at a scale of 1:500, taking into account the red lines. The area of ​​the site under consideration is 1.7 hectares. The following objects and structures are located on the territory: - snow storage area; - checkpoint; - barrier - site of local treatment facilities, including: - sand separator-2 pcs.; - oil separator-2 pcs.; - flow meter; - a well with a crusher; - storage tank. The layout of buildings and structures is shown in the drawing Scheme of the planning organization of the land plot M 1:500 code 76/13-PZU1.2. Along the perimeter of the site, lighting poles are installed, and fences of the type EO-2 2000 * 2650 * 1000, with the installation of a gate from the side of the entrance to the site and a barrier with a rack for reading data. To collect melt water, a drainage tray of the Maxi DN110 type is installed - concrete with a grate. Water is discharged from the trays into storm sewer wells located along the perimeter of the snow receiving area. The entrance to the site with a width of 8,0 m is designed from the side of the street. Astronomical. According to SanPIN 2.2.1/2.1.1.1200-03 section 7.1.13 p. 5, the sanitary protection zone of the Local Treatment Plant is 50 m. Measures to protect the road from snow drifts and animals getting on them are not provided due to the fact that the facility is located in a built-up area. The device of artificial structures (bridges and interchanges) is not provided for within the boundaries of the work. According to geological surveys, dangerous natural and geological processes within the boundaries

Constructive decisions

Checkpoint building

To prevent heaving, the blind area was thermally insulated and the soil was replaced by 0.5 m. plates are welded to embedded parts pos.1. Each w.b. the plate must be welded to at least 2 mortgages. This ensures the rigidity of the structure. For this structure prefabricated monolithic shallow foundation slabs are provided in accordance with GOST 21924.0-84, which provide spatial rigidity of the structure. The slabs are made of concrete B25, W4, F200, 170 mm thick, laid on a sand cushion (medium-sized sand) 500 mm thick. The building is one-storey, has a rectangular shape, the overall dimensions in the axes are 2,5 x 10,63 m, the height is 3,215 m from ur. earth. The checkpoint building is designed to provide access control to the territory of the Snow melting site and provide living conditions for the staff. The following premises are provided at the checkpoint: entrance vestibule - 3,8 m2; security room - 7.67 m2; household premises - 6.35 m2; sanitary unit with shower - 4,22 m2;

Foundations for fiberglass tanks

For this underground structure, monolithic foundation slabs were designed to provide spatial rigidity of the structure. The slabs are made of concrete B25, W8, F50, 300 mm thick, placed on concrete preparation (100 mm thick of concrete B7.5). The project provides for a sand cushion (sand of medium size) with a thickness of 150 mm. The design feature of this structure is the possibility of its ascent. To prevent this phenomenon, a foundation slab is made, the dimensions of which are determined based on the provision of the necessary weight. See Appendix 1 for this calculation. During the dry period, this foundation prevents the structure from settling. Three vertical and 5 horizontal, fiberglass tanks, which are based on reinforced concrete monolithic slabs.

Terrain organization plan

The project of horizontal and vertical planning for the facility was made in accordance with SNiP 2.07.01-89 *, SNiP 2.05.02-85 *, SNiP 3.06.06-85 and "Recommendations for the design of streets and roads of cities and rural settlements" TsNIPI of the Ministry of Construction of Russia 1994 , and is presented in the graphic part of the project code 76/13-PZU.1 sheet 3. The site was designed in the AutoCAD Civil 3D software package, taking into account engineering-geological, hydrological and other terrain conditions. The transverse slope along the access road is assumed to be 20 ‰, along the sidewalk of the industrial building -10 ‰. For complete safety from the ingress of contaminated melt water outside the snow collection area, the project provides for the installation of a geomembrane made of high-density polyethylene 1,5 mm thick along the bottom and slopes of the earthen trough, as well as embankment of the site with a height of 0,85 m The embankment slope from the side of the site is made of monolithic concrete grade B20W8F200. Concrete side stones BR 300.60.20 with an elevation of 40 cm are installed along the perimeter of the site. To drain water from the pavement structure, drainage was laid from corrugated pipes D = 110 mm wrapped with Taipar SF-32 geotextile material with drainage leading to storm water wells. The slope of the drainage repeats the slope of the trays. Drainage pipes are laid along the carriageway tray at a distance of 0,4 m from the onboard one. The vertical layout of the snow receiving area on the drawing 76/13-PZU1.3 "Plan of relief organization".
