Nowadays, more and more tunnels have the problem of crystallization and blockage in the tunnel drainage system. Among them, crystallization and blockage of drainage pipes are particularly frequent. The blockage of tunnel drainage pipes will prevent groundwater from being drained away in time. In mild cases, it will cause water leakage in the tunnel. In severe cases, it will cause damage to the tunnel lining structure and affect the safety of tunnel operations. The tunnel transverse drainage pipe is also an important part of the tunnel drainage pipe. It is blocked frequently and is difficult to clean. Therefore, it is necessary to provide a device to prevent the problem of crystal blockage in tunnel lateral drainage pipes.

From the perspective of prevention, some experts have proposed some methods to solve the problem of crystallization blockage in tunnels, such as the patent number CN201720138517.6 and the utility model patent "A Device for Preventing Crystallization in Tunnel Drainage Pipes through Electric Fields" with Announcement Number CN206477883U, which proposed A metal layer is embedded in the tunnel drain pipe and energized, creating an electric field that inhibits the crystallization of water in the drain pipe. However, this device has problems such as complicated installation and unclear preventive effect, and is not practical enough.

Nowadays, almost all related technologies to prevent the problem of crystallization and blockage in drainage pipes have problems such as complex structures and insufficient cleaning. They are either only effective in the short term, require changes to the structure of the tunnel, or require higher costs. Overall, they are not very good. to solve the current problem of blocked drainage pipes in tunnels.
