Post-lifting reinforcement construction method for asphalt concrete pavement inspection well

Abstract

The present invention aims to provide a post-lifting reinforcement construction method for an asphalt concrete pavement inspection well. The post-lifting reinforcement construction method comprises: carrying out regular hexagon setting-out with the center of a well lid as a center point and the diameter length of the well lid as the inscribed circle radius of the regular hexagon; cutting the sidelines of the regular hexagon; removing asphalt and concrete in the range of the regular hexagon to a certain depth; mounting an inspection well post-lifting base reinforcement cage in the pothole, with a plurality of adjusting bolts fixed to the inspection well post-lifting base reinforcement cage and a leveling steel plate mounted on the adjusting bolts; mounting an inspection well post-lifting base formwork in the inspection well; placing a well seat on the leveling steel plate, leveling the well seat by means of the adjusting bolts and the leveling steel plate and enabling the well seat toreach the elevation; pouring concrete to form an inspection well post-lifting base, and before initial setting of the concrete, spreading a layer of ordinary Portland cement on the surface of the concrete. This method solves the problem of a particular altitude difference between the well lid and the original pavement in the post-lifting reinforcement position of the inspection well, and achievescolor harmony of the surface of the inspection well post-lifting base with black pavement.

Description

technical field [0001] The invention belongs to the field of road construction, and in particular relates to a back-lifting reinforcement construction method for an inspection well on an asphalt concrete road surface. technical background [0002] In the construction of urban road reconstruction, the conventional method of lifting and transforming the inspection well is to pour the concrete base under the well seat first, and then lay the asphalt concrete surface course after installing the well seat and well cover. However, in actual construction, it has been found that the following problems exist in paving the asphalt concrete surface after lifting the inspection well first: 1) There will be a certain height difference between the manhole cover and the original road surface, which will not only cause certain obstacles to the mechanical paving operation , and after the entire pavement is painted black, the joint between the manhole cover and the asphalt surface layer is pr...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a construction method for asphalt concrete pavement inspection wells, which solves the problem of disturbing the original pavement structure layer, and solves the problem that the manhole cover and the original road surface will be formed between the inspection well after the reinforcement. For a certain height difference, the color of the lifting base surface and the black road surface after the inspection well are coordinated
