Intelligent tunnel construction safety monitoring system

Abstract

The invention relates to an intelligent tunnel construction safety monitoring system which comprises a mobile platform, and an arch member and a terminal which are installed on the mobile platform, wherein the arch member abuts against the top and the side wall of a tunnel, a plurality of stress detection elements are distributed on the surface of the arch member in a matrix, the stress detection elements are made into an arch by adopting an elastic material, and the stress detection elements are enabled to abut against the top and the side wall of the tunnel to form resonance and pressure sensing; and the stress detection elements are connected with the terminal and are used for uploading detection data, a resonance model, a stress model and a tunnel collapse model of the top and the side wall of the tunnel in tunneling and static states under different geological conditions are built in the terminal, and when the detection data is greater than normal data and approaches to the tunnel collapse model, the terminal sends out an alarm, and the detection structure is improved, so that the stress change in the tunnel can be continuously detected in the tunneling process, dynamic monitoring in the tunnel is realized, and the reliability of data is improved.

Description

technical field [0001] The invention relates to the field of construction safety, in particular to an intelligent tunnel construction safety monitoring system. Background technique [0002] Tunnel construction is a very common situation in the field of engineering construction. The important lifeline of the national economy - highway, due to its unique flexibility and superiority, plays an irreplaceable role in other modes of transportation, and one of the important components of highway engineering structure is also tunnel . With the continuous development of technology, the scale of tunnel construction is getting bigger and bigger, and the length is getting longer and longer. However, the larger the scale of the tunnel, the greater the technical difficulty. Due to the complex construction environment, relatively high risks, and difficult management, the safety of construction personnel is always the top priority of tunnel construction.

Problems solved by technology

However, the larger the scale of the tunnel, the greater the technical difficulty. Due to the complex construction environment, relatively high risks, and difficult management, the safety of construction personnel is always the top priority of tunnel construction.

[0003] Among them, the main safety hazards of tunnel construction still lie in the two aspects of hypoxia and tunnel collapse. In the past, monitoring was carried out by man-made measurement and observation, and then evaluation and calculation were carried out. It was impossible to truly evaluate the safety of tunnel construction. The data is static, so what will happen to the deformation of the tunnel, and the potential safety hazards brought by these deformation data cannot be predicted and analyzed. Once the problem is discovered late, it will cause huge losses.
