A kind of roadbed construction method of highway reinforced concrete pavement

Abstract

The invention discloses a subgrade construction method for highway reinforced concrete pavement. The subgrade construction method includes the following steps: step 1: prefabrication of reinforced concrete pavement components; step 2: excavation and laying of the base; step 3: reinforcement The assembly of the concrete pavement component and the base; step four: laying of the sealing layer and the maintenance layer; the reinforced concrete pavement component in the step one includes concrete blocks, longitudinal steel bars, transverse steel bars, fixing parts, spacers and hooks, wherein: The interior of the concrete block is inlaid with longitudinal steel bars and transverse steel bars, and the longitudinal steel bars and transverse steel bars are connected by binding; the left and right ends of the interior of the concrete block are inlaid with fixing parts, and the fixing parts and the limit parts are set in one-to-one correspondence , and the limit piece is welded with the hook. The subgrade construction method of the reinforced concrete road surface of the highway has a long service life of the subgrade formed after construction, prevents large-area fractures, and is convenient for partial repair of the pavement.

Description

technical field [0001] The invention relates to the related technical field of highway reinforced concrete pavement, in particular to a subgrade construction method of highway reinforced concrete pavement. Background technique [0002] In order to meet the requirements of long-term use of roads and not easy to break, roads with reinforced concrete pavements are widely promoted, and according to different road needs, the subgrade construction methods of reinforced concrete pavements are also different, but the existing subgrade construction methods of reinforced concrete pavements There are still some deficiencies, such as: [0003] The authorized announcement number is CN102127889B "Subgrade Construction Method for Highway Reinforced Concrete Pavement". This invention discloses a roadbed construction method for highway reinforced concrete pavement. The soil is leveled, rolled and compacted; then paved with steel slag in two layers, each layer with a thickness of 95-105 mm; ...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a roadbed construction method of reinforced concrete road surface, to solve most of the roadbed construction methods of reinforced concrete road surface proposed in the above-mentioned background technology, the service life of the roadbed after construction is shorter, easily cause the fracture of the road surface, And the subgrade constructed by the above method is not convenient for partial repair of the road surface
