Constructive decisions

On the section under consideration, the street was designed according to the parameters of a street of local significance. The planning decision of the street provides for a carriageway 9,00 wide into two traffic lanes 4,50 m wide. On the section from PK0 + 40 - PK1 + 76, the width of the carriageway is 10,60 m. The width of the sidewalks adjacent to the carriageway is 3,00m, in the section PK0 + 40 - PK1 + 76 - 1,50 and 2,25 m. Estimated speed is 40km/h. The maximum longitudinal slope along the carriageway is 26‰, along the trays of the carriageway with a sawtooth profile - 4,0-5,0‰. The cross profile of the roadway is assumed to be gable with slopes of 20,0‰, along the sidewalks - 15‰, and directed towards the roadway. The minimum radius of curves in the plan is 60m. Side stones separating the carriageway from sidewalks - concrete BR 100.30.18, in sidewalks and lawns - BR100.20.8. Entrance - granite GPV, the height of the side stone in the area of ​​pedestrian crossings for the movement of people with limited mobility is up to 4,0 cm. Surface drainage is provided in the designed storm water wells located in the tray of the carriageway. In order to avoid waterlogging of the subgrade, drainage is arranged from corrugated pipes with perforation d=110 in the filter, at a distance of 0,4 m from the side stone. Pavement structures are adopted in accordance with the calculations according to ODN 218.046-01: 1.

At the entrances: hot dense fine-grained asphalt concrete type B, grade I, on viscous bitumen BND 60/90, GOST 9128-2009, - 4,00 cm; hot porous coarse-grained asphalt concrete grade I, on viscous bitumen BND 60/90, GOST 9128-2009, - 8,00 cm; crushed granite grade 800, fraction 40-70, with rivets, GOST 8267-93, 25607-2009 - 22,0 cm; fine sand (content of silt-clay fraction 5%), Kf≥3m/day, GOST 8736-93*, – 50,00 cm. 3. On the sidewalks: asphalt concrete hot sandy dense type G grade II, GOST 9128-2009 - 4,00 cm; hot sandy highly porous asphalt concrete grade I, GOST 9128-2009 - 4,00 cm; crushed granite grade 800, fraction 40-70, with gusseting, GOST 8267-93 - 15,00 cm; fine sand (content of silt-clay fraction 5%), GOST 8736-93 * - 30,00 cm. At the PK2+60 section, it is planned to restore the structures of the railway crossing (non-public railway tracks): KZhD 1420/2994/174 slab - 17,4 cm; granite crushed stone fr.5-10 - 4 cm; reinforced concrete sleeper; crushed stone M1000 fr.25-60 GOST 7392-2002 - 30 cm; fine sand of class I GOST 8736-93 - 15 cm. For unhindered passage of the wheel flange, a counter rail device is provided. The landscaping provides for the installation of lawns along the edges of the sidewalks with a width of 65 m on an area of ​​1600 m² with the introduction of a layer of vegetable soil of 1,0 cm.

Engineering equipment, utility networks, engineering activities

The project documentation provides for the laying of a water supply network with a diameter of 400 mm along the embankment to the water pipe dia. 600 mm along the Far East prospect. Pipes PE 100 are provided. Discharge of surface and drainage waters is provided for the nearest manholes of the combined communal sewerage with a diameter of. 1200mm along the embankment and rainwater sewerage diam. 250 mm along the Far East prospect. Two-layer corrugated polypropylene pipes with a stiffness class of SN8 are provided. Rainwater flow rate is 31 l/s, drainage flow - 49 l/s. The gasket is provided in open and closed ways. Based on engineering-geological and hydrological conditions, it is planned to lay polyethylene pipes on a layer of sand 0,6 m thick, backfill with sand 0,2 m above the top of the pipe. In the carriageway, it is planned to fill the trench with sand to the bottom of the pavement. In the lawn, it is planned to backfill the trench with local and imported sandy soil up to the design ground marks. The design documentation for the protection of heat networks was completed as part of a set of design works for the overhaul of the street in the section from the avenue to the embankment, and the reconstruction of the street in the area. Within the boundaries of the work there are sections of heating networks that cross the street: 0,5Du2 mm, 159Du2 mm, 133Du2 mm.
