Roads, improvement

The area of ​​the roadway of the projected site is 8781 m2. The dimensions of the parking spaces are 20 x 4 m, the number is 30. The dimensions of the parking spaces are taken based on the dimensions of the design bus LiAZ 6212 (in accordance with the Design Assignment). The smallest radius of curves in the plan is 24,5 m, in the longitudinal profile - 2000 and 6000 m (concave and convex, respectively). The longitudinal slope is 4-6‰, the maximum is 12‰. The maximum cross slope along the tray of the carriageway is 25‰, along the sidewalks - 10‰. When separating the carriageway from sidewalks and lawns, the installation of side stones 1GP is provided, sidewalks from lawns - BR 100.30.18. Surface drainage is provided in the design storm water wells located in the tray of the carriageway. The roadway structures are adopted in accordance with the calculations of ODN 218.046-01 and are: asphalt concrete hot dense fine-grained type A, on viscous bitumen BND 60/90, grade I - 5,0 cm; asphalt concrete hot porous coarse-grained, on viscous bitumen BND 60/90, grade I - 10,0 cm; crushed granite brand 1000 fr. geosynthetic material "Typar" SF-56. on an existing basis. On sidewalks: asphalt concrete hot sandy dense type G grade II - 4,00 cm; crushed granite brand 800 fr. on an existing basis. The landscaping area is 10524,2 m2. Tree planting is planned in the amount of 38 pieces.

Engineering equipment, utility networks, engineering activities

The design documentation for the construction of a rainwater sewer was completed as part of the project for the construction of a turnaround area on the territory of the former tram ring in the Western part of the island, project code: 021-10-TKR. The project documentation provides for the construction of rainwater sewers from polypropylene pipes D = 315-250 mm with a stiffness class of SN8 TU 2248-004-50049230-2006, with the installation of storm water wells to provide surface drainage from the roadway and drainage of drainage water. The discharge of surface runoff in the amount of 40 l / s is provided for in a combined sewerage system D = 600 mm along the alley with further flow of wastewater to Mine No. 3 of the TKK in the western part of the island in accordance with the drainage scheme developed and agreed upon. Annual volume of stocks: rainwater runoff - 1762,93 m3; melt runoff - 25919,17 m3; drainage flow - 1999,85 m3. To clean surface runoff from oil products from the territory of the reversal ring, it is planned to install local treatment facilities - OM-15 by FloTenk CJSC, with a capacity of 15 l / s. Pipe laying depth - 1,2-3,0 m. Base for polypropylene pipes: crushed stone - 20 cm, sand - 15 see. Scope of work: laying rainwater drainage D = 315-225 mm from polypropylene pipes, laying length - 624,62 m; installation of local treatment facilities. Pipe laying depth - 2,0 m. The design documentation for the transfer of networks was completed on the basis of the Design Assignment to the contract as part of the project for the construction of a turnaround area on the territory of the former tram ring. The project documentation provides for the relocation of the existing cast-iron water supply system D = 50 mm from polyethylene pipes PE 100 D = 110 mm with the installation of a fire hydrant for external fire extinguishing for the future entry of the water supply into the control room building. When crossing the carriageway, it is planned to lay a water pipe in cases D = 219 mm made of steel pipes. The length of the water pipeline is 109,33 m. Depth of laying - 1,8 m. The project documentation provides for the switching of the existing sewer outlet from the control room building D = 300 mm to the designed sewer D = 315 mm in K-7. The existing sewerage D = 315-250 on the territory of the reversal ring is dismantled by washing with sand and installing concrete plugs. The project documentation designed an outdoor lighting device for a bus turnaround, installation of outdoor lighting poles of the Nevsky Prospekt / Arts Square type - 9/17 pcs. with pendant lamps of the ZhSU20M-250-001 type - 35 pcs. For connection, the cable PvVG-1-4x25 was chosen in the ground in a LDPE pipe - 1,200 km. Connection of lamps - from the existing power point of the type ShRU-400 "Victory Park" (from TP-1017), S = 7,12 kVA. The design load of the cabinet after the installation of the fixtures will be S = 72,14 kVA. The increase in load after the installation of fixtures will be S = 11,3 kVA. Power supply reliability category III. Electricity metering - in the existing SHRU-400.
