Assembly-type prefabricated concrete checking well and construction method thereof

Abstract

The invention relates to an assembly-type prefabricated concrete checking well and a construction method thereof. The checking well comprises a well chamber body and a well shaft body which is fixed above the well chamber body; the well chamber body comprises a lower well chamber with a bottom plate and a well chamber cover plate; the upper end of the lower well chamber is opened, the well chambercover plate is fixed to the upper end of the lower well chamber, and a plurality of pipeline reserving holes which are used for installing accessing pipes are formed in the side wall of the lower well chamber; a plurality of fixing seats sleeve the accessing pipes; flange ends are fixed to the parts, close to the lower well chamber, along the outer wall faces of the fixing seats, and a pluralityof fixing bolts penetrate through through holes formed in the flange ends to fix the fixing seats to the side wall of the lower well chamber; the well shaft body comprises a plurality of well shaft modules which are sequentially fixed through assembly up and down; a well shaft cover plate with a well shaft hole formed in the middle is fixed to the upper end of the uppermost well shaft module; thewell shaft and the uppermost well shaft module, the two well shaft modules adjacent up and down, the lowermost well shaft module and the well chamber cover, and the well chamber cover plate and the lower well chamber are in clamping connection through grooves and tongues.

Description

technical field [0001] The invention relates to an assembled prefabricated concrete inspection well and a construction method thereof, belonging to the technical field of urban pipe network facilities. Background technique [0002] The inspection well is an important structure in the underground pipeline, which has an important impact on the performance of urban functions, environmental protection and people's lives. At present, the materials and construction technology of underground pipeline inspection wells in our country are still relatively backward, and clay bricks are mainly used for construction, which has lagged behind the rapid development of cities in our country. Therefore, in the future, prefabricated structures will be an inevitable trend in the development of municipal engineering. [0003] Since the underground drainage pipe network is gravity flow, each inspection well is located at a different elevation of the pipe inlet and outlet, and each inspection wel...

AI Technical Summary

Problems solved by technology

[0003] Since the underground drainage pipe network is gravity flow, each inspection well is located at a different elevation of the pipe inlet and outlet, and each inspection well may also be connected to pipes of different elevations from all directions. Existing prefabricated inspection wells use The circular modules are stacked vertically in the form of sitting grout, which causes an irreconcilable contradiction between the fixed opening elevation and the required elevation (especially when there are two or more external pipes) of the prefabricated annular module concrete standard parts

This is also the fundamental reason why prefabricated inspection wells have been difficult to promote and use

[0004] In addition, prefabricated inspection wells need to be assembled continuously, and their airtightness is difficult to guarantee
