Abstract

The invention discloses an inflatable type water-stop internal expanding ring device for storing underground pipeline water seepage, and relates to the field of underground pipeline projects. The inflatable type water-stop internal expanding ring device comprises a steel ring (1), a steel ring (2), a steel ring (3), a steel ring (4), a steel ring (5), a steel ring (6), a movable bolt (6), a fixedbolt (7), an inflatable type rubber water-stop belt (8), a gas valve (9) and a valve (10). The inflatable type rubber water-stop belt is adopted between a steel sleeve ring and the inner wall of a pipeline for filling, has certain toughness, is not liable to damage, also can generate certain deformation, and can fill a gap between the steel sleeve ring and the inner wall of the pipeline better toachieve certain sealing effect. Meanwhile, the gas valve for the inflatable rubber water-stop belt is reserved on the steel sleeve ring for regulating gas pressure intensity of the inflatable belt inreal time.

Description

technical field [0001] The invention relates to the field of underground pipeline engineering, in particular to an inflatable water-stop internal expansion ring device for repairing water seepage in underground pipelines. Background technique [0002] Pipe jacking technology is a non-excavation underground pipeline construction technology. It builds a working well and a receiving well on the ground, puts the machine head with excavation capability into the working well, and uses the thrust of the jack and the excavation capacity of the machine head. The machine head is sent into the soil step by step, and finally the machine head reaches the receiving well to form a through underground pipeline. [0003] During the jacking construction of the pipe jacking project, when passing through the stratum rich in groundwater, water seepage or even water leakage may occur between the pipe joints due to various factors. External water, soil and sand poured into the pipeline, and event...
