Emergency road slab made of composite material and mounting method thereof

Abstract

The invention belongs to the road equipment used for traffic security, in particular to an emergency road slab made of a composite material and a mounting method thereof. The emergency road slab comprises an L-type flange which is arranged at the two adjacent and peripheral edges of the road slab and is concave downward and mounting holes thereon; a connecting element penetrates between the mounting holes of the adjacent road slabs; a secondary slab is fixedly connected below the road slab which is the same side with the L-type flange and is coplanar with the lower part of the L-type flange; the connecting element is assembled by a pre-buried sleeve and the mounting holes and comprises a shell which is matched with the inner wall of the pre-buried sleeve in a matching manner, has a convextop part and is clamped and connected with the upper end of the inner hole thereof, a rotating shaft which is arranged in the shell and has the periphery matched therewith in a rotating manner or a clearance manner, and a clamping plate fixed at the bottom end of the rotating shaft; an axial positioning structure is arranged between the rotating shaft and the shell; and the top part of the rotating shaft is connected with a wrench. By rotating the wrench, the rotating shaft and the clamping plate, the invention realizes the axial and radial positioning of the road slab, solves the problems that the prior art has little load capacity and can not be disassemble and assemble fast and the like, and has the advantages of fast disassembling and assembling and high bearing capacity, etc.

Description

technical field [0001] The invention belongs to the road surface equipment used in the field of traffic guarantee, in particular to a composite material emergency road panel and an installation method thereof for meeting the passage of vehicles in unfavorable geological areas such as muddy and sandy beaches. Background technique [0002] Utility model patent 200520012913.1 discloses a mobile and fast paving engineering road slab. Its technical solution is to use square plastic plates with connecting edges around them, and connect and fix different plates through bolts. Among them, there are two adjacent connecting edges. The female connection hole and the fastening hole, in addition two adjacent connection sides are shaped on the male connection tenon, and the male connection tenon is matched with the female connection hole of other plates. The main problem of this road slab scheme is that the connection between the slabs adopts the method of male connection tenons and femal...

AI Technical Summary

Problems solved by technology

Due to the use of laminated FRP materials, this technical solution has the characteristics of corrosion resistance and light weight. At the same time, the L-shaped plate can realize rigid connection and effectively prevent mud (sand), but the upper surface of the connected road slab is flat and the lower part protrudes Most of the pavement is suspended and the lower part of the connector protrudes. For soil areas with poor passability and high bearing capacity (such as dehydrated clay areas, hard pavement sidewalk areas, etc.), it is easy to cause damage to the pavement. At the same time, its connection The threaded connection of the device is easy to be stuck by sand and other materials, and it cannot be quickly disassembled.

In addition, due to its design and structure, the design thickness of the plate is relatively thin, usually about 9mm, and double layers cannot be laid to improve the bearing capacity, which cannot meet the application of vehicles in soft soil areas.
