An anti-collapse waterproof device for construction

Abstract

The invention discloses an anti-collapse waterproof device for construction, which belongs to the technical field of building construction. The anti-collapse and waterproof device includes a plurality of drainage bolts evenly distributed on the surrounding rock, the peripheral wall of the drainage bolts is provided with a number of permeable holes, and the inner of the drainage bolts is filled with bolt filter elements; the adjacent covers distributed in the longitudinal direction pass through the drainage branch pipes It is connected to drain the seepage water to the drainage main pipe arranged near the bottom of the surrounding rock; the backing plate is sleeved on the drainage bolt, and is connected with the main body of the anti-collapse frame through the first spring; a plurality of pressure sensors are arranged between the first spring and the main body of the anti-collapse frame. Between the main bodies of the anti-collapse frame; the pressure sensor and the alarm device are all electrically connected to the controller. On the basis of the inherent support function of the traditional bolt, the drainage bolt of the present invention also acts as a drainage channel for water seepage inside the surrounding rock, so as to avoid the water seepage forming a water passage on the inner and outer surfaces of the surrounding rock, resulting in collapse. A backing plate is set on the pole, and the force of the backing plate is detected by a pressure sensor to detect the deformation of the surrounding rock and prevent collapse.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an anti-collapse waterproof device for construction. Background technique [0002] Underground engineering refers to the underground civil engineering that goes deep below the ground for the development and utilization of underground space resources. [0003] In order to prevent the surrounding rock from collapsing and the falling of stones, the underground engineering support is supported and protected. Shotcrete support is one of the common underground engineering support methods. In the fixed-point conical compression zone, if the bolts are arranged radially at a certain distance along the underground engineering cavern, under the action of the anchoring force, the conical compression zones formed around each bolt are overlapped and connected to each other, forming a space in the surrounding rock. Continuous compression zone, this area can not only maintain its ...

AI Technical Summary

Problems solved by technology

[0004] When construction is carried out in the permeable stratum, rainwater or groundwater seeps from the soil gap to the underground cavern, and the surrounding walls of the cavern are prone to form irregularly distributed water passages, which are likely to cause landslide accidents

In the prior art, the waterproof device for underground engineering is to lay a non-woven buffer layer on the initial support of the surrounding rock, then put a plastic block on it and fix it with a nail gun, and finally weld the plastic block and the waterproof board with a welding torch. , prevent water from flowing into the cavern through waterproof boards; this method can indeed prevent water from flowing into the cavern in the non-water-rich area, and collapse through the support structure. Considering the formation of the water channel and the impact of the expanded water channel on the overall support, it is impossible to prevent landslides in advance. Once an accident occurs, it will directly threaten the life safety of the construction personnel and affect the construction progress, causing immeasurable losses
