Tunnel water inrush expansion plugging structure based on diversion consolidation technology and using method thereof

Abstract

The invention discloses a tunnel water inrush expansion plugging structure based on a diversion consolidation technology and a using method thereof. The tunnel water inrush expansion plugging structure comprises a pipe body, a shell structure is arranged on the pipe body, a stabilizing pipe is arranged at one end of the pipe body, a suction device is arranged at the other end of the pipe body, a cooling structure is arranged between the shell structure and the pipe body, and a plurality of reinforcing structures are arranged on the shell structure; the shell structure comprises an inner pipe matched with the pipe body, a plurality of supporting ring pipe units matched with one another are arranged on the inner pipe, and a gap is formed between every two adjacent supporting ring pipe units;and the cooling structure comprises a box body, a plurality of connecting pipes are arranged on the box body, the connecting pipes are connected with a cooling pipe wound on the outer wall of the pipe body through sealing connecting pieces, and a pump body structure is arranged on one connecting pipe. By the adoption of the structure, uncontrollable water flow is changed into controllable and divertable water flow, water pumping diversion and expanding agent mixture positioning plugging at multiple positions are convenient, slow water flow is effectively and temporarily condensed, and positioning plugging of the expanding agent mixture in a film bag is convenient.

Description

technical field [0001] The invention relates to the field of tunnels and underground engineering, in particular to a tunnel water inrush expansion sealing structure based on diversion consolidation technology and a method for using the same. Background technique [0002] The mechanical effects of groundwater include hydrostatic pressure and strong water pressure. These two effects can cause hydraulic splitting of the rock mass, increase the crack chain and increase the opening degree, thereby increasing the penetration force and breaking through the local water barrier function. , the groundwater table rises, resulting in water gushes and mud outbursts. Therefore, water is the biggest source of water and mud inrush disasters, followed by high pressure. Tunnels are generally buried at a relatively large depth. After excavation by blasting, the original equilibrium pressure is broken and it is in a high-pressure state. There is also unfavorable geology. Tunnels generally have...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a tunnel water inrush expansion sealing structure based on diversion and consolidation technology and its use method, which solves the problem that existing devices cannot efficiently handle water inrush in irregular tunnels, and there is still a high risk To solve the problem, the pipeline can be connected to divert the water inrush, and the uncontrollable water flow can be changed into a controllable and divertable water flow. When the actual water flow in the project is very large, the diversion and blocking can reduce the water flow; Carry out multiple pumping diversions around the site where the project is implemented, and position and seal the expansion agent mixture to reduce the water flow at the site where the project is implemented; use cooling materials to temporarily condense the slow water flow, and then use the expansion agent mixture in the film bag to position and seal blockage, effectively solve the problem of water inrush, and provide a safety guarantee for engineering practice
