Description

Technical Field

[0001] The utility model relates to the field of tunnel engineering, in particular to a tunnel water and mud burst disaster early warning test device. Background Art

[0002] As the focus of water conservancy, hydropower and transportation engineering construction shifts to the western mountainous areas and karst areas with extremely complex topographic and geological conditions, when building underground tunnel projects or excavating tunnels, the complex tunnel environment during construction can easily induce large-scale, sudden water and mud disasters, causing casualties, construction delays, damage to machinery and equipment, increased investment costs, and many other problems. In actual projects, water and mud are often an important factor in engineering construction.

[0003] The existing early warning test device is not convenient for installing and disassembling cameras. Generally, the early warning test device monitors water and mud bursts by installing cameras in the tunnel, and the cameras are generally fixed with bolts. When installing and disassembling the cameras, tools are required to install and disassemble them. The installation and disassembly process is relatively troublesome, which increases the workload and reduces the work efficiency. The cameras cannot rotate back and forth. Generally, the cameras are fixed on the inner wall of the tunnel, and the shooting direction of the cameras is fixed. Since the tunnel is long, a large number of cameras need to be installed in the tunnel to achieve monitoring without blind spots, which not only increases the cost of use, but also increases the amount of later maintenance and reduces the practicality. In order to solve the above-mentioned problems, we propose a tunnel water and mud burst disaster early warning test device. Utility Model Content
