Description

Technical Field

[0001] This utility model relates to the field of tunnel engineering seepage control technology, specifically to an external drainage device for seepage in the arch of a tunnel composite lining. Background Technology

[0002] Tunnels are engineering structures buried underground, representing a form of human utilization of underground space. Tunnels can be categorized into traffic tunnels, hydraulic tunnels, municipal tunnels, mining tunnels, and military tunnels.

[0003] In the field of tunnel engineering, water leakage in composite lining arches has long plagued the safety and stable operation of projects. If leakage is not handled properly and in a timely manner, it will not only erode the tunnel structure and reduce its durability, but may also cause a series of serious problems such as short circuits in electrical equipment and slippery road surfaces affecting driving safety. Currently, external drainage devices are used to deal with common tunnel leaks.

[0004] Existing external drainage devices lack an effective impurity removal mechanism during drainage, causing impurities carried in the water to accumulate at the water inlet and block the drainage pipe. Once the drainage pipe is blocked, not only is the drainage efficiency greatly reduced, but the water level in the water inlet frame may also rise, causing the leaked water to flow back into the tunnel and further aggravate the damage of the leaked water to the tunnel structure. Therefore, an external drainage device for leaked water in the tunnel composite lining arch is proposed. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides an external drainage device for seepage water in a composite tunnel lining arch. This device solves the problem that impurities carried in the water easily accumulate at the water inlet, thus clogging the drainage pipe. Once the drainage pipe is clogged, not only is the drainage efficiency greatly reduced, but the water level in the inlet frame may also rise, causing the seepage water to backflow into the tunnel and further aggravating the damage to the tunnel structure.

[0018] (III) Beneficial Effects

[0019] This utility model provides an externally mounted drainage device for water leakage in the arch of a tunnel composite lining. It has the following beneficial effects:

[0020] (i) The external drainage device for seepage water in the composite lining arch of the tunnel has a cleaning mechanism equipped with a reciprocating threaded rod driven by a motor. After the motor is turned on, the reciprocating threaded rod rotates and drives the control block and the cleaning brush connected thereto to move back and forth horizontally in the water receiving frame, thereby achieving the purpose of cleaning the impurities inside the water receiving frame and thus preventing the impurities from clogging the filter plate. Through the meshing of the toothed plate with the gear fixed on the cleaning rod, the cleaning rod can rotate as it moves with the control block. The rotation of the cleaning rod can clean the cleaning brush and prevent impurities from adhering to the surface of the cleaning brush, thereby ensuring the continuous and effective cleaning performance of the cleaning brush.

During installation, the storage frame is precisely positioned by the positioning rod on the bottom of the water receiving frame and the positioning plate on the outer wall of the storage frame. After positioning, tightening the bolts completes the installation, ensuring the accuracy and stability of the storage frame installation. Attached Figure Description
