A coilable flexible emergency pavement and its preparation method

Abstract

The invention discloses a coilable flexible emergency pavement and belongs to the technical field of design of temporary emergency roads. The emergency pavement comprises a first polyurethane rubberized fabric, a second polyurethane rubberized fabric, reinforcement layer rubberized fabrics, reinforcement supporting rods and polyurea coatings, wherein the reinforcement supporting rods are transversely arranged on the first polyurethane rubberized fabric at equal intervals in the length direction of the first polyurethane rubberized fabric; the second polyurethane rubberized fabric covers the reinforcement supporting rods so that the reinforcement supporting rods can be tightly wrapped in a sealed space which is formed by the first polyurethane rubberized fabric and the second polyurethane rubberized fabric through press fitting; the reinforcement layer rubberized fabrics are arranged on the two sides of the second polyurethane rubberized fabric in the length direction of the second polyurethane rubberized fabric; and the polyurea coatings are arranged on the surfaces of the reinforcement layer rubberized fabric and the surface of the second polyurethane rubberized fabric. The invention further provides a preparation method of the coilable flexible emergency pavement. The coilable flexible emergency pavement can be used continuously in regions with low bearing capacity, and meets the requirement for building of temporary emergency roads in special regions under emergencies.

Description

technical field [0001] The invention relates to the technical field of temporary emergency road design, in particular to a coilable flexible emergency road surface and a preparation method thereof, which are used in public safety, resource exploitation, construction, accident emergency repair, etc. for temporary road construction. Background technique [0002] In my country's current highway construction, the development of temporary emergency road construction in special areas such as beaches, farmland, wetlands, soft and muddy areas with low bearing capacity is relatively slow. In order to realize passage under this road, the technical schemes usually adopted include: 1) civil engineering reinforcement road; 2) detachable road surface connection; 3) mechanized laying. Among them, civil road reinforcement is a commonly used method, which requires a large amount of civil materials, and the construction speed is slow, time-consuming and labor-intensive; the disassembled road ...
