Tunnel construction collapse early-warning method and system

Abstract

Provided is a tunnel construction collapse early-warning method and system. The tunnel construction collapse early-warning system comprises multiple fixing plates, multiple rock-soil deformation sensing sensors and at least one data processing terminal, wherein the fixing plates are fixed to the inner wall of a tunnel in the horizontal and / or longitudinal direction of the tunnel, the rock-soil deformation sensing sensors are fixed to the fixing plates and used for detecting tunnel state information, and the data processing terminals are used for receiving the tunnel state information sent by the rock-soil deformation sensing sensors, comparing the tunnel state information with warning conditions and judging whether an alarm is needed or not. The tunnel construction collapse early-warning system detects the state information of the inner wall of the tunnel through matching of the rock-soil deformation sensing sensors and the fixing plates. Due to the fact that the inner wall of the tunnel deforms before collapse occurs and accordingly change of the state information measured by the rock-soil deformation sensing sensors is caused, collapse early-warning can be made according to the change of the information and an alarm is given out to avoid property loss and loss of life or personal injury of workers when the state information detected by the rock-soil deformation sensing sensors changes.

Description

technical field [0001] The invention relates to tunnel engineering, in particular to an early warning method and an early warning system for tunnel construction collapse. Background technique [0002] In many road projects, tunnels need to be excavated, and tunnels are prone to landslide accidents during the excavation process. In the prior art, landslides are avoided by pouring concrete on the tunnel inner wall of the tunnel, please refer to figure 1 and figure 2 , there are three layers of reinforcement measures for the tunnel. The first layer is the first layer of concrete 8, the second layer is the steel frame 6, and the third layer is the second layer of concrete 7. The area where all three layers are poured is a safe area, but in Concrete pouring cannot be completed immediately at the position where the excavation has just been carried out. This position is the high-risk area where landslides occur, and there will be a section between the high-risk area and the safe...

Problems solved by technology

In the prior art, landslides are avoided by pouring concrete on the tunnel inner wall of the tunnel, please refer to figure 1 and figure 2 , there are three layers of reinforcement measures for the tunnel. The first layer is the first layer of concrete 8, the second layer is the steel frame 6, and the third layer is the second layer of concrete 7. The area where all three layers are poured is a safe area, but in Concrete pouring cannot be completed immediately at the position where the excavation has just been carried out. This position is the high-risk area where landslides occur, and there will be a section between the high-risk area and the safe area where only the first layer of concrete 8 and steel frame 6 are poured. The second layer of concrete 7 has not been poured. This area is still in danger of landslides. This area is a dangerous area. Once the dangerous area and high-risk area collapse without warning, it is very easy to cause casualties and property losses.
