[0002] The tunnel drainage system plays a key role in the durability of the tunnel structure and the safety of operation. The water in the tunnel longitudinal drainage pipe is introduced into the central drainage ditch through the transverse drainage pipe and discharged out of the tunnel. Whether the tunnel transverse drainage pipe is unobstructed is crucial to ensure the effectiveness of the drainage system. Therefore, it is necessary to study the structure of the tunnel transverse drainage pipe.

[0004] In the above-mentioned prior art, the end of the inspection pipeline connected to the transverse drain pipe will protrude from the tunnel lining surface, causing damage to the tunnel pavement, and during the inspection and unblocking of the transverse drain pipe, normal traffic in the tunnel cannot be carried out. If the inspection and unblocking is only carried out through the inspection pipeline connected to the longitudinal drain pipe, the length of the transverse drain pipe inspection and blockage unblocking will be long, and the efficiency of the transverse drain pipe inspection and blockage unblocking will be poor.
