A road repair module and its construction method

Abstract

The invention discloses a road repair module, which comprises a prefabricated block, the prefabricated block is in the shape of a truss, the inside of the prefabricated block is provided with continuous steel reinforcement, and the edge slope of the prefabricated block is provided with irregular corrugations. pleats, the prefabricated block is installed in the subgrade that needs to be filled, and the edge of the road surface around the subgrade is provided with a slope extending to one side of the subgrade, and a circle of connection area with an inverted trapezoidal section is formed in front of the road surface and the prefabricated block. Positioning holes are evenly opened at the bottom of the connection area, and ground piles are fixed in the positioning holes, and fixed claws are fixedly installed around the ground piles in the connection area. The road repair method of the present invention is suitable for cement concrete roads and asphalt concrete roads. , by filling the connection layer in the connection area, irregular folds are provided on the slope of the prefabricated block and the slope of the road surface to ensure the stability of the connection layer, shorten the construction period of the road surface, and reduce the financial cost.

Description

technical field [0001] The invention relates to the technical field of road surface modular repair, in particular to a road repair module and a construction method thereof. Background technique [0002] A local repair structure and repair method for asphalt pavement with the application number "CN201810146400.1" in the prior art, which includes a prefabricated module, the prefabricated module adopts a wedge-shaped body, and its four sides are uniformly changing slope surfaces. The prefabricated module is made of concrete pouring, and a distributed reinforcement structure is arranged in the interior of the prefabricated module near the top surface at a certain distance, and a vertically downward insertion reinforcement is provided at each intersection of the distribution reinforcement structure, and the insertion reinforcement The top of the roof is bent downward at the node position connected with the distributed rib structure, and its extension section at the bottom of the ...

AI Technical Summary

Problems solved by technology

[0003] However, the partial repair structure of the asphalt pavement mentioned above still has obvious defects during use: 1. The construction scheme of the above-mentioned device is only limited to repairing the asphalt pavement, and cannot guarantee the repair of the cement concrete pavement, and most of the low-grade roads use cement concrete The poured road surface cannot be repaired, and the practicability is greatly reduced; 2. The above-mentioned device only combines the prefabricated module with the road through structural glue, and fixes it with the foundation through the extension section at the bottom of the prefabricated module. This connection method is frequently loaded and stressed. It is difficult to ensure the stability of the connection, and the gap between the prefabricated module and the road surface is squeezed against each other, which will easily cause the repaired part to wear and the gap will increase
