Problems solved by technology

[0002] In the tunnel excavation process, in order to deal with various hard rocks and reduce the excavation period, blasting treatment is often required, but the destructiveness caused by blasting cannot be fully predicted, so it may cause the excavated area to collapse. In order to protect the excavated area Tunnels near blasting need to be reinforced
The traditional reinforcement method is mainly to temporarily install support frames. Since these support frames are all temporarily built, it is very troublesome to assemble and disassemble

Abstract

The invention relates to the technical field of tunnel construction, in particular to a tunnel blasting anti-collapse and stabilization device. The tunnel blasting anti-collapse and stabilization device comprises a base, wherein supporting seats are fixedly installed at four corners of the base through bolts, and walking wheels are installed at the lower ends of the supporting seats through bearings; and driven wheels fixed concentrically to the walking wheels are installed at the inner sides of the supporting seats through the bearings, and a power device is fixedly installed under the base.The tunnel blasting anti-collapse and stabilization device has the beneficial effects that the supporting position can be changed conveniently and fast at any time according to the progress of the tunnel excavation, so that an excavated tunnel can effectively resist the destruction of nearby explosives, the collapse of the tunnel is prevented, the life safety of construction personnel is effectively guaranteed, due to the supporting positions of a side supporting plate and a main supporting plate can be changed at any time by a jacking push rod and an angle adjusting motor, the device can further effectively adapt to different sizes of tunnels, and the use mode is easy, the security is high, and the device has high practical value.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to an anti-collapse stabilization device for tunnel blasting. Background technique [0002] In the tunnel excavation process, in order to deal with various hard rocks and reduce the excavation period, blasting treatment is often required, but the destructiveness caused by blasting cannot be fully predicted, so it may cause the excavated area to collapse. In order to protect the excavated area Tunnels near blasting need to be reinforced. The traditional reinforcement method is mainly to temporarily install support frames. Since these support frames are all temporary, assembly and disassembly are very troublesome. [0003] If a new type of tunnel collapse device suitable for tunnels of different sizes is invented, it can effectively solve such problems. For this reason, we provide an anti-slump stabilization device for tunnel blasting. Contents of the invention [0004...
