Tunnel collapse double detection system

Abstract

The invention discloses a tunnel collapse double detection system. The system comprises two tunnel collapse detectors, a number of positioning modules and a rear control center. Two tunnel collapse detectors are arranged at the foot of entrance and exit of a tunnel, and are connected with a CORS network. Two tunnel collapse detectors check and level the relative position parameters of each other in the CORS network to ensure that an alarm signal is sent to a rear control center through the CORS network when the relative position parameters of two tunnel collapse detectors are different from each other. A number of positioning modules are arranged in mountains around the tunnel, and are connected with a satellite-based Beidou positioning system via wireless connection. The rear control center accesses the CORS network and the satellite-based Beidou positioning system. The tunnel collapse double detection system provided by the invention has the advantages of accurate detection effect and reliable performance.

Description

technical field [0001] The invention relates to the field of tunnel collapse detection, in particular to a dual detection system for tunnel collapse. Background technique [0002] With the continuous development of the national economy, the construction of highways, railways and water diversion projects in our country is advancing by leaps and bounds. In order to meet the requirements of high speed, high cost and low cost, the number of tunnel projects is increasing, and the scale and difficulty of tunnel construction are also increasing. Although The level of tunnel construction has also made great progress, but due to various reasons, tunnel collapse is still unavoidable, especially small and medium-sized vault collapses are more common, and small and medium-sized vault collapses generally form caves of different sizes, some caves The collapse will stabilize to a certain extent, while some caves will continue to collapse continuously or intermittently. There is therefore ...
