AI Technical Summary

Technical Problem

The existing prefabricated inspection wells cannot be used normally because they are lower than the pavement elevation, and the customized prefabricated inspection wells are expensive, and the on-site prefabricated molds are bulky and inconvenient to transfer.

Method used

A prefabricated inspection well mold is designed, including inner mold, outer mold, bracket and hanger. Through the cooperation of the bracket and hanger, a stable annular space is formed, allowing for height compensation casting construction of the inspection well.

Benefits of technology

It solves the problem that prefabricated inspection wells cannot be used normally because they are lower than the road elevation, and realizes rapid installation and disassembly on-site. The structure is simple and light, making it easy to carry and transfer.

Abstract

The present invention provides a prefabricated inspection well mold and a method for making the inspection well, belonging to the technical field of inspection wells, comprising an inner mold, an outer mold, a bracket, and a hanger for suspending the outer mold in the air, wherein the outer mold ring is arranged on the outer periphery of the inner mold and forms a cavity for accommodating the inspection well; the bracket comprises a vertical upright pole, a first sleeve, a second sleeve and a push rod; the bottom of the upright pole is fixed with a plurality of horizontal cross bars arranged along the outer periphery of the upright pole; the first sleeve is sleeved on the cross bar and can slide along the cross bar, and when the first sleeve slides, the inner mold is pushed to be close to the inner wall of the inspection well; the second sleeve is sleeved on the upright pole and can slide along the upright pole; the two ends of the push rod are movably connected with the first sleeve and the second sleeve respectively; the hanger is supported on the second sleeve. A stable annular space for pouring concrete is formed between the inner mold and the outer mold, and on-site construction can be carried out to compensate for the height of the inspection well, thereby solving the problem that the prefabricated inspection well cannot be used normally because its height is lower than the road surface elevation.
