Abstract

The invention relates to an automatic monitoring and warning device of tunnel subsidence and an application method thereof. The device is mainly used for monitoring and warning subsidence in the excavation processes of tunnel and subway projects and timely warning for the sections where subsidence deformation is too large and subsidence speed is too high. The device mainly comprises a support device, telescopic devices and a reaction device, wherein the support device is attached on the side walls of a tunnel and a subway; the telescopic devices are fixed in the tunnel and each telescopic device is connected with a processor; the processor is connected with a computer and the reaction device; the reaction device comprises an electronic horn and a signal lamp. The automatic monitoring and warning device of tunnel subsidence has the benefits of being small in device size, good in the continuity of measuring time, timely in warning, accurate in the prediction of accident location, good in stability, convenient to carry and overhaul, low in cost and easy to popularize.

Description

technical field [0001] The invention relates to monitoring of vault settlement of tunnels and subways, specifically for continuous monitoring and alarming of sections with excessive settlement or excessive settlement speed, and accurate positioning of accident sections to grasp the situation of the entire tunnel. Background technique [0002] Nowadays, due to the increase of traffic pressure, excavating tunnels and building urban subways have become an important way to relieve traffic pressure. The concealment of tunnels and urban subways is relatively large, and the geological conditions during the construction process are complex, and the potential accident hazards cannot be predicted. The sudden accidents in tunnels and subways are mainly manifested in the collapse of the vault and the inrush of water and mud from the side wall. There are many methods to control the settlement of the tunnel vault, such as the invention patent with the application number CN201210455807, wh...
