Pipe-jacking hole-entering sealing ring beam structure

Abstract

The invention discloses a pipe-jacking hole-entering sealing ring beam structure. The pipe-jacking hole-entering sealing ring beam structure comprises a pipe-jacking pipe joint, a pipe joint socket, areceiving well wall, a well wall pre-buried casing pipe and a sealing ring beam; the pipe joint socket is arranged at the end of the pipe-jacking pipe joint; the pipe-jacking pipe joint is located inthe well wall pre-buried casing pipe; the well wall pre-buried casing pipe is arranged in the receiving well wall; a gap is reserved between the pre-buried casing pipe and the pipe-jacking pipe joint; and the pipe-jacking pipe joint is fixed in the well wall pre-buried casing pipe through the pipe joint socket. According to the pipe-jacking hole-entering sealing ring beam structure, the pre-buried casing pipe and the pipe joint socket of the receiving well wall are fully utilized and are connected with a steel structure through anchoring steel bars; then the cast-in-place reinforced concretesealing ring beam is implemented, so that differential settlement between the pipe-jacking pipe joint and the receiving well wall can be greatly reduced; and underground water leakage, ground subsidence and the like in a gap between the pipe-jacking pipe joint and the well wall pre-buried casing pipe are relieved, and the service life of the structure is prolonged.

Description

technical field [0001] The invention relates to the technical field of pipe jacking hole sealing, in particular to a ring beam structure for pipe jacking hole sealing. Background technique [0002] At present, the pipe jacking construction method plays an important role in the field of urban municipal public pipelines, and has a wide range of applications. However, after the pipe jacking enters the receiving hole of the receiving well, the gap of about 100 mm between the pipe joint and the well wall casing is generally only sealed with flexible materials such as cement; at the same time, all pipe jacking pipes are basically located below the ground depth, and often below the groundwater level; at the same time, there is a change in the water level in the pipeline, and it is subjected to working conditions such as the self-weight of the upper water and soil, and the ground load. differential settlement. Therefore, water leakage often occurs in the gap between the pipeline a...

However, after the pipe jacking enters the receiving hole of the receiving well, the gap of about 100 mm between the pipe joint and the well wall casing is generally only sealed with flexible materials such as cement; at the same time, all pipe jacking pipes are basically located below the ground depth, and often below the groundwater level; at the same time, there is a change in the water level in the pipeline, and it is subjected to working conditions such as the self-weight of the upper water and soil, and the ground load. differential settlement

Therefore, water leakage and other phenomena often occur in the gap between the pipeline and the wall of the receiving well. In the case of long-term water leakage, it may even cause safety accidents such as the settlement of the surrounding ground, roads, and municipal pipelines.

It can be seen that the design of the entrance of the pipe jacking pipe joint is a difficult problem in the design of the pipe jacking receiving well, and it also greatly affects the damage of the surrounding environment and economic waste
