Inspection well installation structure and construction method

Abstract

The invention relates to an inspection well installation structure and construction method, and belongs to the technical field of inspection well construction. The structure comprises a first foundation pit, a second foundation pit and a base arranged in the first foundation pit, wherein an inspection well is arranged on the base, a well seat is arranged at the top end of the inspection well, a well cover is arranged on the well seat, a plurality of stand columns are arranged between the inspection well and the side wall of the first foundation pit, pressure bearing rings are detachably arranged at the top ends of the stand columns, a lower foundation soil layer is arranged below the pressure bearing rings and arranged between the side wall of the first foundation pit and the outer peripheral surface of the inspection well, an upper foundation soil layer is arranged above the pressure bearing rings and arranged between the side wall of the first foundation pit and the outer peripheralsurface of the inspection well, and an asphalt layer is arranged between the well seat and the second foundation pit. According to the structure and the method, the thickness of the upper foundation soil layer above the pressure bearing rings is relatively thin, so that the upper foundation soil layer can be easily compacted, and when the lower foundation soil layer below the pressure bearing rings settles, the pressure bearing rings do not settle along with the lower foundation soil layer under the supporting effect of the stand columns, so that the phenomenons of settling and cracking of pavements surrounding the well cover is reduced.

Description

technical field [0001] The invention relates to the technical field of inspection well construction, in particular to an installation structure of an inspection well and a construction method thereof. Background technique [0002] The inspection well is set up for the convenience of installation and maintenance of the power supply, water supply, drainage, communication and other lines of the underground infrastructure. At a certain distance, it is convenient for regular inspection of ancillary structures. When backfilling the roadbed during the installation of the inspection well, the roadbed around the inspection well is relatively loose because the compaction machine cannot approach the surroundings of the inspection well at close range for compaction. The pavement structure will gradually sink, and then under the action of vehicles and pedestrians, the road surface around the manhole cover will sink and crack, which will affect the safety of vehicles and pedestrians.

When backfilling the roadbed during the installation of the inspection well, the roadbed around the inspection well is relatively loose because the compaction machine cannot approach the surroundings of the inspection well at close range for compaction. The pavement structure will gradually sink, and under the action of vehicles and pedestrians, the road surface around the manhole cover will sink and crack, which will affect the safety of vehicles and pedestrians.
