Problems solved by technology

Many highway tunnels are built in Guizhou and other areas. Many tunnels are built in remote places that are inconvenient for frequent human inspections. Moreover, natural disasters such as landslides and mudslides are prone to occur in mountainous areas, which pose a great threat to personal safety.

Abstract

The invention provides a tunnel vertical settlement and arch wall pressure stress monitor and a cloud monitoring and early warning system. The monitor comprises a settlement sensing mechanism, a pressure stress sensing mechanism and a data processor used for transmitting signals collected by the settlement sensing mechanism and the pressure stress sensing mechanism. The settlement sensing mechanism comprises a left horizontal laser sensing instrument and a right horizontal laser sensing instrument which are horizontally arranged, and the pressure stress sensing mechanism comprises a stress sensor. The laser induction instruments are used for receiving laser induction instrument signals of the four monitors nearest to the monitor and judging the distances between the monitors and the monitors where the corresponding induction instruments are located and whether the corresponding monitors have angle deviation or not, and therefore whether vertical settlement happens to the tunnel or notis judged. Meanwhile, the internal pressure of the supporting layer and the rock-soil layer is sensed through the pressure stress sensing mechanism, so that the stress pressure change of the arch wallis monitored.

Description

technical field [0001] The invention relates to a device for detecting the vertical settlement of a tunnel and the compressive stress of an arch wall, and a monitoring and early warning system composed of the device. Background technique [0002] With the rapid improvement of my country's economic construction, my country's infrastructure construction has also developed rapidly, and the construction of national infrastructure has been carried out in large numbers in the north and south of our country. The construction of various major projects such as transportation, water conservancy and hydropower has ushered in great development, and has also greatly promoted the construction of various long (deep) tunnel projects. Guizhou Province, located in the southwestern part of China, has rolling mountains and many canyons. The construction of transportation construction is not easy and most of the tunnels are built. Guizhou Province has abundant rainfall and belongs to the platea...
