SUBSTANCE: invention can be used to drain water from the roadbed and other bulk structures. Method of constructing the drainage structure includes the formation of a channel with the subsequent laying along the bed of a protective covering in the form of a flexible material with the formation of protrusions above the bottom surface of the bed. Protrusions are made of perforated split pneumatic machines, which are located on the bottom of the bed alternating successively stepped protrusions. Outer circumference of the pneumatic bodies has a hemisphere directed by a convex upward in the cross section. Lower end face of the pneumatic bushes is fixed by a plate relative to the bed bottom.

Description

The invention relates to the construction of railways and roads and can be used to divert water from the subgrade and other bulk structures.

A drainage system is known in which, in order to increase the reliability of operation, a blind area is proposed to prevent soil erosion and, in general, waterlogging of the main tray is prevented (Copyright certificate SU No. 1606567, E01F 5/00 of 11/15/1990).

However, the proposed system is cumbersome and expensive.

A drainage structure is known in which an increase in the operational reliability of a drainage structure is achieved by the presence of an additional tray (Copyright certificate SU No. 94904, E01F 5/00 of 08/07/1982).

However, this construction involves the operation of the maintenance service, which is difficult in the winter-spring period (drifts of snow, ice, snow cakes) and is not economically feasible.

A known method of erecting a soil structure, which consists in the fact that by creating a profile of the structure on the promontory slopes of the steep slope, an additional volume of gravel and pebble soil is laid with the formation of a broadened upper part of the structure (Copyright certificate SU No. 1719531, ЕОВВ 7/06 of 03/15/1992).

The disadvantages of this method is the high complexity of the work and high material consumption.

Closest to the proposed method is a method of building a drainage structure, which consists in cutting a ditch, strengthening its bottom and walls with a coating and giving the bottom of the ditch a shape with protrusions shaped in longitudinal section, as a coating, use geotextile material that is used on the bottom surface, walls and fasten edges along the length of the ditch. The protrusions are formed from geotextile material bonded with the formation of transverse cages, filled to stiffen with soil or other material when used as dampers for the speed of water flow. The clips are filled with U-shaped brackets - one for each, with fixation in the soil of the bottom of the ditch (Patent RU No. 2025551, E01F 5/00 of 12/30/1994).

The disadvantage of this method is the high complexity of the work, and the fact that the protrusions form without taking into account changes in water flow rates, and this requires increased costs of geotextile material and U-shaped staples. In addition, it requires large capital expenditures. In addition, the voids of the protrusions are additionally filled with soil or other material to stiffen the protrusion.

The task to which the invention is directed is to reduce the complexity of the work, reduce the consumption of building materials by eliminating the filling of the internal cavity with other material, in addition, the use of elasticity and deformation of the pneumatic tire.

EFFECT: profile of protrusions from split pneumatic tires provides the role of shock absorbers - dampers of water flow rate.

The technical result is achieved in that the problem is solved in such a way that in the method of constructing a drainage structure, including forming a channel with subsequent laying on the channel of a protective coating in the form of a flexible material with the formation of protrusions above the bottom surface of the channel, the protrusions are made of perforated split pneumatic tires, which are arranged the bottom of the channel alternating sequentially stepped protrusions, and the outer circumference of the pneumatic tires has a hemisphere directed convex upward in cross section, and izhnyaya end face of tires is fixed relative to the bottom plate channel.

In FIG. 1 shows a drainage structure with dampers of water flow rate; in FIG. 2 - drainage structure, section; in FIG. 3 - pneumatic tires for the damper and the place of mounting plates, general view; in FIG. 4 - fragment of the mounting of the pneumatic tire.

The method is implemented as follows.

A ditch is cut in the ground 1. A geotextile material 2 is laid out with a release over the edges of the ditch and the edges of the material are deepened into the ground. On top of the geo-textile material, a used split pneumatic tire 3 is fixed in the form of protrusions, the width of which is equal to the width of the ditch 1. The lower end face is fixed with a plate 4 to the main canvas 2 and fixed to the ground with pins 5. The pneumatic tires 3 in the form of protrusions have perforations with holes 6. In this case, the water flow will pass both through the top on the outer circumference in the form of a hemisphere of the pneumatic tire 3, and through the perforated holes 6 (into the cavity of the pneumatic tire 3). The shape and flexibility of the pneumatic tire (factory tires are made in different diameters and their flexibility), which have served their useful life, and now can be used as protrusions - with a buffer. The flow, changing the opposite direction, reduces the speed of water in the ditch 1.

The height of the pneumatic tires 3 (protrusions) relative to the bottom of the channel, arrange the profile in compliance with the calculated dimensions based on the maximum possible building height from filling with water in the ditch 1. Thus, when implementing the method, the water flowing down the slope of the ditch 1 is delayed by the pneumatic tires 3, smoothly poured as through the top, it passes through the perforation of the holes 6 in the wall of the pneumatic tire 3, and as the water moves with the dampers, the flow rates of the water, changing direction, reduce the speed of the water in the ditch 1.

For example, the height of a perforated split air tire with fastening above the bottom of the channel depends on the distance between the vertices alternating along the length of the channel in the form of protrusions, the flow rate of water, the shape of the convexity of the pneumatic tire itself, its rigidity and manufacturing flexibility used in the operation of automobile tires as a whole.

When implementing the method does not require additional filling of the building material for the inner cavity of the protrusion and stiffening with soil, which dramatically reduces the complexity of the work by at least 3 times, reduce the consumption of geotextile material. This ensures high stability and flexibility of the drainage structure.
