Inspection well mounting structure and construction method thereof

Abstract

The invention relates to an inspection well mounting structure and a construction method thereof. The well mounting structure comprises a foundation pit, a well lid, a walling crib, a castable layer and an aggregate layer, wherein the aggregate layer is arranged on the bottom of the foundation pit; the castable layer is arranged on the upper part of the foundation pit; the middle parts of the aggregate layer and the castable layer are provided with channels which are adaptive to the inner diameter of the walling crib; the walling crib is fixed in the castable layer, and the upper surfaces of the walling crib and the castable layer are flush with a road surface; the well lid is movably mounted in the walling crib; a rubber sheet gasket is arranged between the walling crib and the well lid; two openings are symmetrically arranged at the two sides of the well lid or at the two sides, close to the well lid, of the walling crib; and the well lid and the walling crib are manufactured by an RPC active powder concrete material. According to the inspection well mounting structure, the well mounting can be completed without the need of using large rod pressing equipment, so that the damage caused by repeated rolling compaction of the large road pressing equipment to the well mounting structure is avoided; and the inspection well mounting structure is convenient and quick to mount, is low in construction cost, is firm and attractive in structure, is high in fitting precision of the well lid and the walling crib, and is not liable to move and turn over.

Description

Technical field [0001] The invention relates to a municipal facility inspection well, in particular to an inspection well installation structure and a construction method thereof. Background technique [0002] In the installation and construction of well tools in inspection wells of municipal facilities, when installing well tools on the completed inspection wells, it is often necessary to repeatedly vibrate the hot asphalt concrete around the periphery of the well tools with a diameter of less than 1m, causing the surrounding structure of the well to repeatedly bear Depression, damage and subsidence, etc., affect traffic safety. The traditional well tool installation structure uses asphalt concrete, which has the advantage of being uniform and beautiful with the pavement material, but there are many disadvantages: one is the need to use road rollers and hot asphalt for construction, which increases the cost of machinery and materials; second, the construction speed is slow, and ...

AI Technical Summary

Problems solved by technology

[0002] In the installation and construction of well tools in inspection wells of municipal facilities, when installing well tools on the inspection wells that have been built by masonry, it is often necessary for the road roller to repeatedly shock and compress the hot asphalt concrete around the outer periphery of the well tool with a diameter of less than 1m, resulting in the repeated bearing of the structure around the well tool. Depression, damage and subsidence, etc., affecting traffic safety

The traditional well tool installation structure adopts asphalt concrete, which has the advantage of being unified and beautiful with the pavement material, but there are many disadvantages: first, it needs to use road rollers and hot asphalt for construction, which increases the cost of machinery and materials; second, the construction speed is slow, and the road roller needs to be repeated Rolling around the well tool; third, because the asphalt concrete structure is easily damaged after being stressed, subsidence affects traffic

In addition, in the municipal roads, it is often encountered that the manhole cover of the inspection well is displaced, turned over, or the structure around the well tool is collapsed or damaged, which affects the travel of vehicles and pedestrians and the city environment

The traditional well tools are made of cast iron, and its disadvantages are mainly reflected in: first, the manufacturing precision of cast iron well tools is not high, the matching precision is poor, and the well cover and the well circle are prone to shift or flip when the force is applied; second, the manufacturing cost is high , the color is not uniform with the road surface, so it is not beautiful enough; the third is that cast iron well tools are easy to lose, which brings hidden dangers to road safety
