Abstract

FIELD: construction.SUBSTANCE: polymer prefabricated road pavement structure consists of plates assembled of triangular prisms having equilateral triangles in their section. Device comprises webs of solid monolithic (welded) structure, having upper layer, which is rectangular web, and the lower layer has the shape of a series of isosceles flattened hollow prisms combined by long rectangular sides located on the road surface across the direction of movement of transport, and for roadsides and ramps - along. In the warm season, the roadway webs are laid on the underlying layer of sand or loosened soil previously applied on the road bed in winter with application of the dry layer.EFFECT: invention relates to design of roads and aerodromes on hard and weak soils.1 cl, 4 dwg

Description

The invention relates to the construction, namely to the construction of roads, airfields, foundations for various structures, power lines, as well as to other structures that work directly with the ground, both with solid and weak.

The aim of the invention is to significantly reduce the cost of the construction of pavement by replacing the construction of layers of pavement from sand (50 cm), crushed stone (30 cm) and cement concrete and / or asphalt concrete (20 cm) on a layer of canvases of polymer (plastic) precast pavement with the underlying layer of sand or loosened soil, while the cost of funds is reduced by up to 2 times and the time of construction by means of a polymer (plastic) precast pavement device at least 4 times.

Known utility model [Patent of the Russian Federation, useful model No. 139226, IPC Е01С 5/08, published in 2013 "Precast pavement"] [1]. According to this invention, the precast pavement has a plate of triangular prisms having equilateral triangles in cross section. The author and patent owner of this solution is Antonov Alexander Sergeevich.

The disadvantage of the utility model [1] is a triangular prism, having a rectangular cut in the face, which creates risks of reducing the density of the soil at the ends of the precast pavement and shifting it during assembly and operation of the precast pavement, narrows its use on soils requiring an increase in the contact area prism with the surface of the roadway.

The objective of the invention is that the precast pavement device comprises, as part of a plate, assembled from triangular prisms having equilateral triangles in section, in which, according to the invention, the polymer (plastic) precast pavement device comprises one-piece monolithic (welded) construction webs having the top layer, which is a rectangular canvas, and the bottom layer has the shape of a series of equilateral, two-sided truncated hollow prisms that are joined by long rectangular sides, installed on the basis of the roadway across the direction of traffic, and for roadsides and ramps along, in the warm season, the devices of the polymer (plastic) precast pavement are laid on the underlying layer of sand or loosened soil previously deposited on the road base (in winter with a dry layer applied) , for reinforced sections of roads and structures of airfields, foundations for various structures, power line pylons, as well as other structures, an addition from above is applied Vuh layers stacked webs prizes each other.

The invention is illustrated by drawings, where in FIG. 1. shows the element of the lower layer of the UPSPSD web in the form of an isosceles two-sided truncated triangular hollow prism with an angle and height depending on the required area of contact with the underlying layer of sand or loosened soil.

The essence of the work of the present invention is to eliminate the shortcomings in the use of the device [1], which has the risk of shifting the paving in the direction of a rectangular cut triangular prisms. FIG. 2. shows the UPSPSD web and the arrangement of the isosceles two-sided truncated triangular hollow prisms across the traffic, on the roadsides and at the ramps along the traffic.

The situation can be remedied by specifying the height, angle at the apex of the triangular hollow prism and the angle of double-sided truncation of triangular hollow prisms that form the required bearing surface area of the precast pavement, thanks to this design, a network of ground isosceles triangular bilateral truncated prisms preventing polymeric ) canvases on the road base, taking into account the triangular ground prism formed laid on the side of the UPPSDP along the movement i transport.

FIG. 3. Shows the conjugation of the UPPSD fragment with the underlying layer of sand or loosened soil.

FIG. 4. shows UPSPSD with three layers of canvases for reinforced sections of roads and structures of airfields, foundations for various structures, supports of power lines and other structures.

Claims (1)

A polymeric precast pavement device, having a plate assembled from triangular prisms having equilateral triangles in cross section, characterized in that it contains sheets of solid monolithic or welded structures having an upper layer that represents a rectangular web, and the lower layer has the shape of a series of the long rectangular sides of the isosceles bilateral truncated hollow prisms located on the basis of the roadway across the direction of traffic, and for shoulders and rides - along, in the warm season, polymeric precast pavements are laid on the underlying layer of sand or loose soil previously deposited on the road base at air temperature below zero with a dry base layer applied.
