Fully automatic real-time monitoring and early warning system and method for inverted arch structures

Abstract

The disclosure discloses an automatic real-time monitoring and early warning system and method for an inverted arch structure, including a detection system, including an ultrasonic flaw detector and a pressure gauge, which are configured to detect the internal structure of the inverted arch, check whether there is damage, and measure the circumference of the lower part of the inverted arch. rock pressure; the wireless signal transmission system is configured to transmit the information collected by the detection system to the central control platform; the central control platform is configured to analyze the pressure of the surrounding rock under the inverted arch based on the received information on the inverted arch of the tunnel during the operation period change, establish a continuous change model of the surrounding rock pressure at the lower part of the inverted arch, judge the degree of influence of the current surrounding rock pressure on the safety of the inverted arch, and give corresponding early warnings according to the degree of influence; the power supply system is configured as a detection system and a wireless signal transmission system The provision of electricity can provide valuable scientific data for the study of the stress and deformation characteristics of the surrounding rock of the tunnel during the operation period, as well as the hydrogeological development around the tunnel.

Description

technical field [0001] The disclosure relates to a fully automatic real-time monitoring and early warning system and method for an inverted arch structure. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] At present, most of the tunnels have problems such as water seepage to varying degrees, excessive deformation of surrounding rocks, and uplifting of tunnel inversions during the operation period, which seriously threaten the stability of the tunnel structure and driving safety. Among them, the tunnel invert, as a part of the tunnel structure, plays a huge role in restraining the deformation of the surrounding rock and ensuring the stability of the overall structure of the tunnel. However, the problem of the uplift of the subgrade caused by the uplift of the tunnel invert seriously threatens the safety of the project. It is especially pro...

Problems solved by technology

[0006] In order to solve the above problems, this disclosure proposes a fully automatic real-time monitoring and early warning system and method for an inverted arch structure. The disclosure obtains the state information of the inverted arch structure through the detection system in the tunnel, and then wirelessly transmits it to the central control platform for analysis , identify the abnormal deformation of the inverted arch structure, give early warning of possible safety problems in the inverted arch, and realize automatic real-time monitoring and early warning of the inverted arch during the operation period
