Abstract

Usage: irrigation of street green spaces and removal of surface water on the sides of the roadway. SUMMARY OF THE INVENTION: Tray 1 adjacent to the carriageway is made with external stiffening ribs 2 with a height less than the height of the tray. Curb 5 consists of separate elements mounted on a stiffener between pavement 6 and the wall of tray 1. 8 Il.

Description

The invention relates to the construction of roads built in hot climates, as well as irrigation trays for irrigation of street green spaces and removal of surface water on the sides of the carriageway, and can be used in hydraulic engineering as well as in road construction. hard and non-rigid types of coatings.

An irrigation irrigation tray, made of concrete, has a trapezoidal cross-section,

Placing irrigation trays in the cross section of city streets has a number of drawbacks: poor architectural and aesthetic appearance of the streets due to the lack of curbstones; the walls of the tray under the influence of dynamic loads of vehicles.

The frequent destruction of the irrigation chute is due to the fact that with constant wetting of the edge of the roadway, the modulus of base deformation decreases. The intense dynamic load from the vehicles and the reduction in the deformation of the base of the road are the main cause of the destruction.

Closest to the present invention is a road device containing a passing part and a drainage tray and a border adjacent to it.

A disadvantage of the road structure is that this structure does not have transverse stiffeners. Their absence very often leads to the destruction of the sides of the tray during loading and unloading.

The purpose of the invention is to reduce material consumption.

The goal is achieved by the fact that the tray is made with external stiffeners at least on the adjacent to the carriageway.

part of the wall, with the height of the ribs less than the height of the tray, and the curb consists of individual elements mounted on the ribs.

Along the edges of the tray 1 (Fig. 2), lateral stiffening ribs 2 (Fig. 3) reinforced with reinforcement 3 (Fig. 8) in the form of a ledge 4 (Fig. 5) are arranged at a certain distance (Fig. 4). The ledge 4 serves as the base of the curb 5 (FIG. 3), which is clamped to the road surface 6 (FIG. 3). The void between the chute and the curb is filled with the grasping material 7. The presence of the step 4 ensures the stability of the curbstone against the action of the tipping forces arising

when hitting the wheels of vehicles in operation.

As a result of using the proposed device (stiffener), an increase in reliability and durability is achieved.

irrigation tray, both during loading and unloading, and during operation. This ensures the improvement of the architectural and aesthetic appearance of the street and the installation of curbstones. This in turn

ensures traffic safety especially in winter.
