De-icing is carried out mainly by chemical methods, which leads to the entry of large masses of chemical reagents into water basins and soil massifs, polluting surface and ground waters and posing a threat to flora and fauna and humans. Storing snow for its natural melting in spring or dumping it into the river network of the city leads to significant changes in the chemical composition of the main components of the environment (soil, water, air). In this regard, it is necessary to effectively remove large snow and ice masses and their disposal with minimal technical and economic costs. The use of sewers to melt snow collected from roads is justified. The capacity of urban treatment facilities is sufficient to receive runoff from snow that has melted in snow melting points. This solution was used in this project. The estimated capacity of the stationary snow melting station is 7 m000/day (for snow). The need of the design object for electricity is: 3 kVA (snow melting point), power supply category - III (see Appendix 517). The project does not provide for the use of raw materials and secondary resources. Land plots seized for temporary and permanent use are not produced. The area of ​​the site for the placement of a stationary snow melting point is 9 m². Special technical conditions for the development of the project were not required.

Indicators of strength and deformability: φ=220, c=0,09 kgf/cm2, E=90 kgf/cm2. The snow-melting chamber is a structure measuring 39.78m x 20.7m in axes, 6.8m deep from the ground level (bottom bottom). For a relative mark of 0.000m, the level of planning was taken, corresponding to the absolute mark of +4.200 in the Baltic system of heights. The design of the snow melting chamber consists of load-bearing external walls, load-bearing internal walls and columns, spacer beams, a foundation in the form of a slab that acts as the bottom of the tank and a metal deck. Reinforced concrete structures of walls, partitions, foundations, columns, spacer beams are made monolithic. The geometric immutability of the structure is ensured by the joint work of the bottom, walls, columns and beams. The junctions of the spacer beams to the walls, as well as the junctions of the crossbars to the columns and the junctions of the columns to the foundation slab in frame structures are made rigid. Metal flooring in the form of separate removable gratings rests freely along the short sides on the outer and inner walls and the crossbar of the longitudinal frame structure. The foundation slab rests on an elastic base and is a support for wall and column structures. The snow melting chamber is designed for a temporary vehicle load, a load from stationary crushers of individual production (SDIP) and a load of sediment from melted snow. The maximum temporary vehicle load is 20,0 tons per rear bogie. The load from stationary crushers is 8 tons per 1 support. The calculation was performed using the calculation complex SCAD version 11.5. At the base of the structure are (EGE 2) silty sands of medium density, gray, saturated with water. The thickness of the layer ranges from 1600 to 2000mm. Underlying layers: EGE 3 - light silty loam, layered, with sand interlayers, gray, fluid-plastic; EGE 4 - heavy silty loam, ribbon, brown, fluid. When developing these soils, do not subject them to dynamic loads, under which they liquefy and lose their inherent in their natural state, structural coherence and bearing capacity. When excavating a pit, all measures should be taken to preserve the natural structure of soils in its bottom part. After excavation of the soil of the excavation to the design mark (elev. -6,870), the Tefond Plus Membrane is laid along the bottom of the excavation in 1 layer on a leveled sandy base and concrete preparation is carried out from concrete class.

The outer walls of the chamber are designed with a thickness of 600 mm, the longitudinal middle wall - with a thickness of 500 mm. The surface of the monolithic concrete of the bottom is sheathed with metal sheets 10 mm thick, the inner surfaces of the walls and columns - with metal sheets 8 mm thick to a height of 1,0 m. from the bottom. Metal sheets made of steel 15KhSND prevent damage to the concrete surface when cleaning the chamber. The metal sheathing sheets are installed using Hilti chemical anchors with a staggered pitch of 500 mm on a 88 mm thick EMACO S20 grout. The corners of columns and beams are protected from mechanical damage by embedded parts from rolled corners.
