Embodiment Construction

[0032] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0033] See attached figure 1 And attached figure 2 , a well circumference reinforcement method of the present invention comprises the following steps:

[0034] Step 1: After the construction of the water-stabilized base of the inspection well 1 is completed; firstly, the boundary of the treatment around the well should be determined. The inspection well 1 is circular and adopts the center lofting method. With the centroid of the inspection well as the reference point, the reinforcement around the well is parallel to the The center line of the road is perpendicular to the center line of the road, the edge of the rectangular well is parallel to the center line of the road along the road, and the direction of the cross road is parallel to the cross section of the road. Use a fossil pen and a long ruler to accurately draw on the top surface of the base;

Abstract

The invention relates to a well circumference strengthening method, and belongs to the technical field of road building. The well circumference strengthening method aims at solving the problem that inthe prior art, the well circumference is prone to cracking and sinking. The well circumference strengthening method comprises the following steps that a strengthening layer boundary is determined onthe upper surface of a water stability base layer; the water stability base layer in the strengthening layer boundary is replaced along the strengthening layer boundary; gravel on a base is tamped, and residues are removed; a concrete cushion layer is poured above the gravel; reinforcing steel bars are installed in a strengthening cavity; a steel ring with the diameter being 670 mm and the thickness being 5 mm serves as an inner mold to be arranged at a well opening in a sleeving manner, longitudinal and transverse lines serve as reference lines to pour concrete between the inner mold and an outer mold, a reinforced concrete strengthening layer is formed, the top face of the reinforced concrete strengthening layer is parallel to the plane where the longitudinal and transverse lines are located, and the distance between the top face of the reinforced concrete strengthening layer and the upper surface of the water stability base layer is the installing height of a well lid; and a plasticthin film is paved on the top face of the reinforced concrete strengthening layer, and watering is carried out for maintenance.

Description

technical field [0001] The invention belongs to the technical field of road construction, and in particular relates to a reinforcement method around a well, in particular to a reinforcement method around a well on an asphalt pavement. Background technique [0002] The inspection well is set up for the maintenance of urban underground infrastructure such as power supply, water supply, drainage, sewage discharge, communication, cable TV, gas pipes, and street lamp lines, and is convenient for installation. It is generally installed at the intersection, turning, pipe diameter or slope change, and at a certain distance on the straight pipe section, which is convenient for regular inspection of auxiliary structures. The inspection well is composed of well base, well shaft, well cover and related accessories. In the campus or on the traffic road, etc.; the inspection wells are of brick structure, and the ductile iron manhole cover is placed on the brick well shaft to connect with ...
