Problems solved by technology
However, the above-mentioned pipe blockage monitoring device mainly has the following disadvantages: first, there are often turns and joints in the tunnel drainage pipe, and the laser detection device cannot realize the turning and is limited; second, the length of the tunnel is hundreds of meters to several thousand meters. Normally, the same is true for the supporting tunnel drainage pipes, or even longer, so the use of endoscopic cameras to detect blockages will also be limited; third, if the original water head is large, and the water pressure changes after blockage is not significant, it may cause the pressure sensor. It is impossible to determine the status of pipeline blockage; finally, the currently commonly used high-frequency geological radar to detect tunnel pipeline blockage is complicated and passive detection

Embodiment 1
[0030] Example 1. A pre-buried clogging monitoring system for tunnel drainage pipes, which consists of Figure 1-8 As shown, the water level monitoring device 7 is included, and the water level monitoring device 7 is connected with the data reading and recording device 10; the water level monitoring device 7 includes a tunnel drainage pipe connector 5, and one end of the tunnel drainage pipe connector 5 is connected to the saddle bypass 2 Connection, the other end of the tunnel drainage pipe connector 5 is provided with a float type liquid level gauge 6, and the float type liquid level gauge 6 is connected with the data reading and recording device 10. The working principle of the float-type liquid level gauge 6 is to use the buoyancy principle of the liquid on the float on the float-ball-type liquid level gauge, and the displacement of the float with the change of the liquid level is converted into an analog linear electrical signal output. The measuring range of the float t...

Description
technical field [0001] The invention relates to the field of tunnel drainage pipeline monitoring, in particular to a tunnel drainage pipeline pre-buried blockage monitoring system and a use method. Background technique [0002] my country's transportation system is developing rapidly, and tunnels are an important part of the transportation system. The tunnel drainage system is prone to problems such as poor drainage and local pipe blockage, which will lead to the overall failure of the tunnel drainage system, thereby increasing the water load behind the tunnel lining, and causing problems such as lining cracking, water leakage, or failure of supporting electrical facilities in the tunnel. As a result, the maintenance period of the tunnel is shortened, which seriously affects the service life and operation safety of the tunnel. [0003] At present, my country's tunnel drainage system is a drainage system composed of "tunnel drainage pipes (including circular drainage pipes, ...
