技术领域technical field

The tunnel drainage system is prone to problems such as poor drainage and partial pipe blockage, which lead to the overall failure of the tunnel drainage system, which increases the water load behind the tunnel lining, and causes 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.

Existing pipeline clogging monitoring devices are roughly divided into laser detection, endoscopic camera detection, pressure sensor, pulse generating device and the like according to the working principle. However, the above-mentioned pipeline blockage monitoring device mainly has the following shortcomings: First, the tunnel drainage pipeline often has turns, joints, etc., and the laser detection device cannot realize the turning and is limited; Normally, the supporting tunnel drainage pipes are also the same, or even longer, so the use of endoscopy cameras to detect blockages will also be limited. It is impossible to determine the status of pipeline blockage; finally, the currently commonly used high-frequency geological radar to detect the blockage of tunnel pipelines is complicated and passive detection.
