Construction installation acceptance method for assembly type inspection well

Abstract

The invention discloses a construction installation acceptance method for an assembly type inspection well. The construction installation acceptance method comprises the following steps that (1) a base groove is excavated; (2) the inspection well installation and pipeline connection are carried out; (3) the base groove is backfilled; and (4) inspection acceptance is carried out. In the step (2), the inspection well is installed in the base groove, a pipeline is connected with the inspection well, 1:2 cement mortar is adopted at a connecting port or 1:2 cement mortar blended with polyurethane is adopted for joint seam, and the seam thickness is 10-15 mm; in the step (3), backfilling and compacting are carried out simultaneously on the two sides of a well chamber, 2: 8 gray soil, coarse sandor gravel is adopted by a backfill material, backfilling reaches the position below a road structure layer, the backfilling width is not less than 400 mm, and the compaction coefficient of the backfilling soil is greater than or equal to 0.95; and in the step (4), whether cracks exist or not in the well chamber and in the wellbore portion are checked, the thickness of a well wall of the inspection well and the size of a reserved hole are checked, and meanwhile, the internal force of an inspection well cover plate, the well wall and a bottom plate is checked. The construction installation acceptance method is easy to construct, the operation is simple and convenient, the construction efficiency is improved, the construction structure performance is good, and the engineering quality is favorably guaranteed.

Description

technical field [0001] The invention relates to the technical field of municipal road construction, in particular to a construction, installation, and acceptance method for a prefabricated inspection well. 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 of pipelines, turning places, pipe diameter or slope changes, and at certain distances on straight pipe sections, which is convenient for regular inspection of ancillary structures. After the inspection well is installed and used for a period of time, occasional cracks, collapses and other events may occur, causing pipeline blockage and even endangering personal safety. The main reasons are that the existing construction and installation methods are unreaso...
