Emergency water sealing rubber sleeve for perforated water bursting of underground space

Abstract

The invention discloses an emergency water sealing rubber sleeve for perforated water bursting of underground space. The emergency water sealing rubber sleeve comprises a flexible rubber sleeve body (1) and an injection pipe (2), wherein the flexible rubber sleeve body (1) is provided with an opening; the injection pipe (2) stretches into the flexible rubber sleeve body (1) from the opening; the injection pipe (2) is provided with an inlet communicated with the outside and an outlet which is communicated with the inner part of the flexible rubber sleeve body (1); the opening of the flexible rubber sleeve body (1) is in sealing connection with the injection pipe (2). According to the emergency water sealing rubber sleeve disclosed by the invention, an underground structure water bursting event caused by the fact that the underground space is perforated can be more effectively treated.

Description

technical field [0001] The invention relates to the technical field of underground structures, in particular to an emergency water-sealing rubber sleeve used for drilling through water inrush in an underground space. Background technique [0002] Underground spaces such as subway tunnel structures are drilled through, causing water inrush incidents in underground structures to occur from time to time. At present, in such emergencies, the traditional treatment method is "blocking", that is, using epoxy resin to block water, and then using Steel plate sealed. [0003] The above processing method mainly has the following disadvantages: [0004] 1) When there is a large amount of groundwater in the formation, the epoxy resin cannot block the water; [0005] 2) From the perspective of the later effect, the parts treated by the above method are the key parts of the later structural water seepage; [0006] 3) After being drilled, a hole is formed from the ground to the undergrou...

AI Technical Summary

Problems solved by technology

[0006] 3) After being drilled, a hole is formed from the ground to the underground structure, which becomes a channel for groundwater to collect, and epoxy resin is used to block the hole in the structure, mainly for the enclosure structure. After wooden wedge water blocking or sandbag back pressure, It is also necessary to drill holes and inject grouting to block the water source behind the enclosure structure, which takes a long time to process and consumes a lot of manpower and material resources;

[0007] 4) Water plugging and grouting cannot be carried out simultaneously
