Abstract

The invention discloses a tunnel top pressure early warning system under complex geological conditions. The tunnel top pressure early warning system under the complex geological conditions comprises atunnel top plate, wherein a supporting wall is arranged between two sides of the tunnel top plate and the ground; a plurality of monitoring points are distributed in the supporting wall in the extension direction of a tunnel; detection devices are arranged at the monitoring points; each detection device comprises a supporting tube and an ultrasonic detector arranged at the upper end of the supporting tube; the ultrasonic detectors are connected with a control box outside the tunnel through transmission wires; the transmission wires pass through the supporting tubes, pass through the supporting wall and a tunnel bottom plate, and is connected to the external control box; and a wireless transmitter is arranged on the control box. According to the tunnel top pressure early warning system under the complex geological conditions, the arranging mode is simple, the arrangement cost can be reduced, the structural condition of the tunnel top plate can be known in time, dangerous situations canbe predicted in time and processed in advance, and the occurrence probability of dangerous accidents can be reduced by notifying passing vehicles in time.

Description

technical field [0001] The invention relates to an early warning system, in particular to a tunnel top pressure early warning system under complex geological conditions, and belongs to the technical field of tunnel construction. Background technique [0002] During the construction of expressways, it is often necessary to dig tunnels for vehicle passage when encountering mountains or steep terrain. However, for complex geological environments, the stability of the tunnel roof is a concern for builders. If the roof bears too much pressure from the mountain, it will cause rupture or even collapse. In order to solve such problems, the common method is to use various support methods to increase the support of the roof. On the one hand, this method will greatly increase the cost of high-speed construction. On the other hand, if serious geological impacts occur, these The support method is not necessarily effective, and the occurrence of dangerous accidents cannot be avoided. C...
