Inspection well in roadway and construction method

Abstract

The invention provides an inspection well in a roadway and a construction method. A prefabricated wellbore connecting body is arranged on the upper part of a wellbore masonry body, elastic connectinglayers are arranged both on the upper surface and the lower surface of the prefabricated wellbore connecting body, an upper transverse supporting body and a lower transverse supporting body are used for providing vertical support to a built-in supporting plate; a particle filling body which is constrained by a wrapping reinforcement bag is arranged on the built-in supporting plate; a circumferential guide rail is arranged on a surface layer, the impact of cutting construction on the surrounding environment is reduced through an airtight vertical plate; an inner column pressure bearing rod anda pressure bearing rod end plate are arranged at the bottom end of an inner column of a hanging mold; an inner groove plate of a formwork is arranged on the inner side wall of a suspended inner mold,the space position of the suspended inner mold is limited by an inner supporting sliding plate and an inner supporting arc plate; and a steam curing cavity of a wellbore raising body is defined by a sealing bag at the bottom of the wellbore, a maintenance cover plate and the wellbore raising body. According to the inspection well in the roadway and the construction method, the difficulty of site construction can be reduced, the construction quality can be improved and the construction environment can be protected.

Description

technical field [0001] The invention relates to an inspection well in a roadway and a construction method that can reduce the difficulty of on-site construction, improve the construction quality and protect the construction environment, belongs to the field of municipal engineering, and is suitable for the installation project of the inspection well in the roadway. Background technique [0002] After a period of use, inspection wells often have a series of common problems such as deformation of the manhole cover, cracking and subsidence of the pavement around the well, which will damage the pavement structure, reduce the service life and operation quality of the road, and affect the stability and safety of passing vehicles. For road reconstruction projects that require surface layer overlaying, the raising quality of the wellbore and the compactness of the surrounding structural layers have always been difficult points in engineering control. [0003] In the prior art, there...

Problems solved by technology

Although this structure can optimize the stress and load transfer of the wellbore, it is difficult to solve the problems of cast-in-place wellbore lifting and quick connection of manhole covers
