[0002] The tunnel construction emergency drainage device plays a vital role in tunnel engineering. It can quickly and effectively remove accumulated water in an emergency and ensure the safety and smooth progress of tunnel construction. The tunnel construction emergency drainage device is an emergency drainage equipment specially designed for tunnel construction. It can be quickly activated when water accumulates in the tunnel and drain the accumulated water to the outside of the tunnel or the designated drainage system.

[0003] Existing tunnel construction drainage devices, such as the one disclosed in publication number CN220621962U, have the advantage of improving the water collection cover to collect leaking or gushing water on the tunnel wall. However, this drainage device generally needs to be moved as a whole into the accumulated water during use, which not only poses a safety problem for the users during operation, but also easily causes water damage to the carrier vehicle. For this reason, we propose an emergency drainage device for tunnel construction. Utility Model Content

[0031] The working principle and use process of this utility model:

[0032] When emergency drainage is required during tunnel construction, the sewage pump 201 at the front end of the remote control trolley 100 is first pulled, so that the sewage pump 201 pulls the connecting rods 204 on both sides forward through the movable wheel 202 at the front end. After the sewage pump 201 moves forward to a suitable distance, the electric push rod 208 in the slide groove 205 can be started. After the electric push rod 208 is started, the tooth block 207 at the bottom of the drive is moved downward to engage with the tooth groove 206 in the connecting rod 204, thereby ensuring the stability of the sewage pump 201 after adjustment. After the sewage pump 201 is stably fixed, the remote control trolley 100 can be used to control the sewage pump 201. The vehicle 100 moves the sewage pump 201 into the accumulated water. After the sewage pump 201 is moved into the accumulated water, the sewage pump 201 and the waterproof motor 307 at its upper end can be started. After the sewage pump 201 is started, the accumulated water will be pumped out. After the waterproof motor 307 is started, the connecting shaft 306 and the gear 305 are driven to drive the gear plate 304 and the outer filter cover 303 at the bottom of the sewage pump 201 to reciprocate, so that the brush 302 at the inner end can be used to clean the blockage in the outer filter cover 303 during rotation, thereby ensuring the pumping efficiency of the sewage pump 201.
