Construction method for vertical main pipe protection of hot spring well in foundation pit

Abstract

The invention relates to a construction method for protecting a vertical main pipe of a hot spring well in a foundation pit, comprising the following steps: 1) arranging a circle of cement mixing piles along the periphery of the vertical pipe of the hot spring well, and metal pipes are respectively inserted in the centers of the cement mixing piles; 2) Excavate the earthwork, and then manually excavate the cement soil of the cement mixing pile; 3) Build a support platform between the metal pipe and the top of the casing; 4) Removably install the wellhead force plate on the support 5) Repair and install the lifting frame on the support platform; 6) Continue to excavate the earthwork by layered excavation, and remove the cement soil layer of the cement mixing pile until the earthwork falls to the bottom of the basement floor elevation. The invention can protect the safety of the structure of the hot spring well vertical pipe itself during the construction process, and the construction progress is fast, and can effectively ensure the normal production and operation of the hot spring well vertical pipe during the construction process.

Description

technical field [0001] The invention relates to a construction method for protecting the vertical main pipe of a hot spring well in a foundation pit, which is mainly used for protecting the vertical main pipe of a hot spring well during the construction process of a basement and ensuring that the vertical main pipe of the hot spring well can operate normally during the construction process of the basement. Background technique [0002] At present, the speed of urban development is accelerating, and the scale of old city reconstruction is constantly expanding. The protection of hot spring resources is particularly important during the construction process. At present, the relevant technologies and applications in this aspect of the engineering construction process are almost blank. The protection of hot spring resources during the construction process mainly includes two aspects, one is the protection of the vertical main pipe of the hot spring well in the foundation pit, and...

AI Technical Summary

Problems solved by technology

[0003] Since the support structure in the foundation pit is relatively complex, there are many construction machines, and there are many cross-operations in various procedures during the foundation construction process, the risk of damage to the structure of the vertical main pipe of the hot spring well is extremely high. In order to protect the vertical pipe of the hot spring well, construction often It is difficult to carry out normally, and it is easy to affect the construction progress, and the hot spring well standpipe during the construction process is difficult to operate and produce normally
