A well-tunnel structure whole-area on-line monitoring bus bar and a method for installing and using the bus bar

Abstract

The invention discloses a well-tunnel structure whole-area on-line monitoring bus bar and a method for installing and using the same. The on-line monitoring bus bar at least comprises a conductor andan insulator, wherein the insulator is provided with a plurality of sensors spaced apart in the length direction and electrically connected with the conductor. The installation and use method comprises the following steps: S1, sensor installation test is completed, S2, laying and installation area leveling treatment; S3, installation and monitoring; By monitoring and analyzing the signals of the sensors in the monitoring bus, the position of the roadway test point is determined to be in the range between two adjacent sensors, so as to realize the structural health monitoring in the whole rangeof the shaft and tunnel structure. The invention realizes the transfer of the sensor installation work from the well tunnel construction site to the ground workshop, and improves the installation quality and efficiency of the sensor. The busbars are arranged along the whole length of the well and tunnel, and the deformation and vibration at any section can be transmitted to the sensors in the adjacent sensing bin through the busbars, so the global monitoring and early warning of the stability of the well and tunnel structure can be realized.

Description

technical field [0001] The invention relates to the technical field of safety monitoring of shafts, tunnels and roadways, in particular to an overall online monitoring busbar of a shaft and tunnel structure and an installation and use method thereof. Background technique [0002] In highway, railway, urban rail, mining, civil air defense and other projects, the stability of any position of shafts, tunnels, roadways and other structures plays a decisive role in the normal operation of the overall structural function. The local deformation and instability of any shaft and tunnel section , Collapse will paralyze the entire structure, and even cause serious casualties. Therefore, it is of great significance to conduct real-time online monitoring of the tunnel structure and accurate "time-space" scale prediction of possible structural instability. However, the existing monitoring methods cannot realize the monitoring in the whole area of ​​the roadway, and more are local monitor...

Problems solved by technology

However, the existing monitoring methods cannot realize the monitoring in the whole area of ​​the roadway, and more are local monitoring from the "point" level. In practical engineering applications, due to the complex construction environment and geological conditions of the tunnel structure, the sensor installation Quality is often not guaranteed, and sensor installation is time-consuming and labor-intensive. In addition, traditional sensor installation requires more cables and connection points. Such sensor layout schemes and monitoring methods have exposed more and more defects in engineering practice. and deficiencies
