Combined quick blocking and wall retaining device

Abstract

The invention discloses a combined quick blocking and wall retaining device, and belongs to the technical field of mining engineering. The combined quick blocking and wall retaining device comprises sealing airbags, a frame, a plurality of transverse telescopic supporting rods, a plurality of vertical telescopic uprights and intercepting water strainers. The frame is formed by sequential connection of a plurality of unit frame bodies. The sealing airbags are fixedly mounted on the outer sides of the unit frame bodies respectively, and adjacent sealing airbags are in close contact. The transverse telescopic supporting rods are horizontally arranged in the frame, and two ends of the transverse telescopic supporting rods are fixedly mounted on unit frame bodies on the left side and the right side of the frame respectively. The vertical telescopic uprights are vertically arranged in the frame, each vertical telescopic upright comprises a jack and a telescopic rod, and one end of each telescopic rod is fixedly connected with the top end of the corresponding jack while the other end of the same is fixedly matched with the frame. The intercepting water strainers are fixedly mounted on the frame. The combined quick blocking and wall retaining device is capable of effectively preventing grout leakage, good in water filtering effect, high in universality, time saving and labor saving in mounting and reusable.

Description

technical field [0001] The invention belongs to the technical field of mining engineering, and in particular relates to a combined fast blocking retaining wall device capable of sealing goafs and preventing filling slurry from flowing into other working faces and polluting roadways. Background technique [0002] The filling mining method refers to the process of mining, advancing with the mining face, and gradually filling the goaf with filling material, so as to achieve the purpose of ground pressure management, control of surrounding rock collapse and surface movement. With the continuous consumption of the existing proven mineral resources, mining is gradually developing towards the deep, and with the influence of factors such as ground temperature, ground pressure and rockburst, the application scope of filling mining method in our country is constantly expanding. [0003] When the filling mining method is actually applied, before the filling material is filled, the seal...

AI Technical Summary

Problems solved by technology

[0005] 1. The block retaining wall has poor bending resistance, and is prone to local displacement and deformation, resulting in collapse and slurry leakage, and the transportation volume is large, the labor intensity is high, and the water filtration effect is low;

[0006] 2. The maintenance period of the concrete structure retaining wall is long, the roadway wall is not tightly sealed, and grout leakage is prone to occur, and the construction cost is high, the versatility is poor, and it cannot be reused;

[0007] 3. The wooden retaining wall has high requirements on the quality of the wood, the processing is time-consuming and laborious, and the wood consumption is large, and the strength is not high enough;

[0008] 4. The construction process of the reinforced flexible retaining wall is complicated, and the quality is difficult to guarantee
