Tunnel-blasting-protection bamboo-raft-reinforced wall and manufacturing method thereof

Abstract

The invention discloses a tunnel-blasting-protection bamboo-raft-reinforced wall and a manufacturing method thereof. The tunnel-blasting-protection bamboo-raft-reinforced wall includes a protective plate and a support frame arranged on the back of the protective plate; the protective panel includes a panel that fits a tunnel opening, and a plurality of reinforced rib strips on the back of the panel; the panel is composed of a plurality of bamboo panels woven from bamboo surface patches; the shape of the multiple bamboo panels is the same as the shape of a tunnel excavation section; the edge size of the entire panel exceeds a tunnel contour line by 50 centimeters; and the multiple reinforced rib strips are welded to the support frame and criss-cross to form a network structure. According tothe bamboo-raft-reinforced wall, before the blasting construction of the tunnel opening section, a bamboo-raft-reinforced stone-baffle wall is closely arranged at a cover arch of the tunnel opening to prevent that some flying stones are thrown too far; baffles need processing in advance; the material cost is low; the wall can be repeatedly used; the flying stone diffusion distance can be effectively reduced; the noise is better reduced; and after processing, the wall can be used many times, the installation is quick, and the work efficiency is high.

Description

【Technical field】 [0001] The invention belongs to the field of blasting protection, and relates to a bamboo row reinforced wall for tunnel blasting protection and a manufacturing method thereof. 【Background technique】 [0002] At present, tunnel construction mainly relies on blasting, which may have harmful effects on protected objects near the blasting area. Such as vibration caused by blasting, individual flying objects, air shock waves, noise, water shock waves, dynamic water pressure, surges, dust, harmful gases, etc. If the blasting area is located near the scenic spot, three warning points should be set up. The 1# warning point is set behind the machinery 200 meters west of the blasting area to prevent people from entering the construction work area through the sidewalk. The 2# warning point is the top of the cave. The fork in the trail 260 meters to the northeast is to prevent tourists from climbing over the fence and entering the construction work area; the 3# warni...

AI Technical Summary

Problems solved by technology

This solution needs to process the baffle in advance, the material cost is high, and it can be reused. A loader is required to push the platform; although it can effectively reduce the flying stone diffusion distance and reduce noise, it needs to repeatedly assemble steel plates, and the work efficiency is low.
