Anti-collapse and waterproof device for construction

Abstract

The invention discloses an anti-collapse and waterproof device for construction, and belongs to the technical field of building construction. The anti-collapse and waterproof device for construction comprises a plurality of draining anchor rods, adjacent covers, a base plate and a plurality of pressure sensors, wherein the draining anchor rods are uniformly arranged on surrounding rock, a plurality of water holes are formed in the peripheral walls of the draining anchor rods, and anchor rod filter elements are filled in the draining anchor rods; the adjacent covers are distributed in the vertical direction, connected through draining branched pipes, and used for guiding seeping water to a draining main pipe arranged close to the bottom of the surrounding rock; the base plate is arranged onthe draining anchor rods in a sleeving mode and connected with an anti-collapse main body through first springs; the pressure sensors are arranged between the first springs and the anti-collapse mainbody; and the pressure sensors and an alarm device are electrically connected with a controller. According to the anti-collapse and waterproof device for construction, the draining anchor rods not only have the inherent supporting function of traditional anchor rods, but also can serve as a channel for discharging seeping water in the surrounding rock, so that a collapse caused by a water channelformed in the outer surface of the interior of the surrounding rock by the seeping water is avoided; and the base plate is arranged on the draining anchor rods, and the stress of the base plate is detected through the pressure sensors to detect deformation of the surrounding rock, so that the collapse is prevented.

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 to develop and utilize underground space resources. It includes underground houses and underground structures, underground railways, highway tunnels, underwater tunnels, underground common trenches, and underground passages for street crossings. [0003] Underground engineering support is the support and protection adopted to prevent the surrounding rock from collapsing and falling stones. The sprayed anchor support is one of the common underground engineering support methods. For the fixed-point conical compression zone, if the anchor rods are arranged radially at a certain interval along the underground engineering cavern, under the action of anchoring force, the conical compression z...

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
