RU2690912C1 - Method of erecting polymer (plastic) prefabricated road pavement - Google Patents

Abstract

FIELD: construction.

SUBSTANCE: method of erection of polymer (plastic) prefabricated road surface is carried out by webs in the form of solid monolithic (welded) structure consisting of upper layer - rectangular web, and a lower layer in the form of a row of isosceles truncated hollow prisms combined by long rectangular sides, which is laid on an underlying layer of sand or loosened soil of the road surface during the warm season, and in winter - on dry underlying layer. Prisms are located on road base across direction of transport, and for roadsides and ramps - along. Pavements of polymer (plastic) prefabricated road pavement are laid with a crane-manipulator of the vehicle placed on the surface of prefabricated road pavements, simultaneously rolling them with their weight.

EFFECT: invention relates to design of roads and aerodromes on hard and weak soils.

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 erecting pavement by replacing the pavement layers of sand, crushed stone and cement concrete and / or asphalt concrete with a layer of polymeric (plastic) precast pavement (PPSDP) with the underlying layer of sand or loosened soil, while the costs Means are reduced to 2 times and the time of construction by means of polymeric (plastic) precast pavement cloths at least 4 times.

The useful model is known. 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 that has 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 and limits its use for soils requiring an increase in the contact area prism with the surface of the roadway.

The objective of the invention is that the method of erection of a polymer (plastic) precast pavement using plates assembled from triangular prisms having equilateral triangles in cross section, in which, according to the invention, the method of erection of a polymer (plastic) precast pavement is carried out in the form of solid monolithic (welded) structure consisting of the top layer, which is a rectangular canvas, and the bottom layer has the shape of a series of combined long rectangular with With the isons of the isosceles bilateral truncated hollow prisms placed on the underlying layer of sand or loosened soil of the roadway during the warm season, and in winter they are placed on the dry underlying layer, while on the road base the prisms are placed across the direction of traffic, and for shoulders and ramps - along, Polymer (plastic) precast pavement canvases are laid by a truck crane on the surface of previously laid precast pavement, while rolling them with its weight (if necessary, in addition to a roller), for sections of roads requiring reinforcement, structures for airfields, foundations for various structures, power line poles and other structures, two more layers of polymeric (plastic) precast road canvases are added to the laid canvas of a polymer (plastic) precast pavement cover stacked prisms into each other.

The invention is illustrated by drawings, where in FIG. 1 ÷ 3. An element of the lower layer of the PPSDP web is shown 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 PPSDP sheet and the arrangement of the isosceles two-sided truncated triangular hollow prisms across the traffic, they are placed along the roadsides and road exits along the traffic,

The situation can be corrected by specifying the height, angle at the apex of the triangular hollow prism and the angle of two-sided truncation of the triangular hollow prisms that form the required bearing surface area of the precast pavement, create a network of soil isosceles triangular two-sided truncated prisms that prevent it from shifting on the road base taking into account the triangular prism formed by the laid PPSDP canvases on the side of the road or at the exit along the traffic.

FIG. 3. Shows the mate fragment PPSDP with the underlying layer of sand or loosened soil.

FIG. 4. PPSDP canvases laid in three layers of canvases for reinforced sections of roads and structures of airfields, foundations for various structures, pylons of power transmission lines and other structures are shown.

FIG. 5 shows the laying and rolling of PPSDP webs with a truck crane on the surface of previously laid PPSDP webs, while simultaneously rolling them with your weight (if necessary, additionally with a roller).
