Composite material road tie plate and assembling technique

Abstract

The invention relates to a composite road backing plate, comprising core material (1), faceplates (2) solidified by fiber cloth layer and resin and set at two sides of the core material (1) and non-skidding coating (3) set at the upper surface of faceplate (2). It is characterized in that the structure of connecting edges of backing plate can adopt male-female connecting edge, iron chain or canvas and so on. The invention can be used in building and repairing of urgent road in civil and national engineering. It is provided with light weight, high intensity, big rigidity, corrosion resistance, anti-stripping, convenient and quick assembly, repeatable usage, no damage for field environment and industrial production. Because the invention is made of light wood or foam core material and resin matrix fiber faceplate and resin column or resin web plate so on are formed on the core material, abilities of compressive resistance and shear resistance are improved while because adjacent backing plates are connected by canvas, iron chain or male-female connecting edge, the road for vehicle are assembled quickly.

Description

technical field [0001] The invention relates to a light-weight and high-strength composite material sandwich structure pavement backing plate, which can be used for quickly building temporary roads or quickly repairing damaged roads, and belongs to the field of building materials. Background technique [0002] When the vehicle passes through unfavorable places such as sandy beaches, swamps or silt, the wheels are prone to sink. In emergency situations, such as: when earthquakes, floods and other disasters occur, the existing road surface engineering is damaged, and urgent repair or construction of traffic lanes is required to quickly transport and transfer materials and personnel. In emergency environments, there is often a lack of sufficient Time to build standard concrete pavement projects, especially in the southeastern coastal areas of my country, where the foundation is weak and the soil quality is poor, mainly muddy soil; at the same time, when the existing pavement pro...

Problems solved by technology

In emergency situations, such as: when earthquakes, floods and other disasters occur, the existing road surface engineering is damaged, and urgent repair or construction of traffic lanes is required to quickly transport and transfer materials and personnel. In emergency environments, there is often a lack of sufficient Time to build standard concrete pavement projects, especially in the southeastern coastal areas of my country, where the foundation is weak and the soil quality is poor, mainly muddy soil; at the same time, when the existing pavement projects are damaged, emergency repairs are required, although conventional Quick hardening cement, ground improvement and other methods can also solve the problem, but it takes a long time and damages the site soil environment

In addition, in large-scale foundation pit projects, earth moving vehicles need suitable backing plates to enter and exit the foundation pit, and the current metal backing plates often have sufficient strength to meet the requirements, but are not rigid enough and easily deformed
