Description

Technical Field

[0001] The utility model relates to the technical field of tunnel drainage, in particular to a temporary drainage device for an initial branch section of a tunnel. Background Art

[0002] At present, the conventional practice for drainage of the primary support section of a tunnel is to directly dig a simple drainage ditch on the side of the tunnel wall for drainage. However, since large vehicles and equipment need to frequently travel in the primary support section during construction, the drainage ditch is often crushed and collapsed, resulting in the need for frequent excavation of drainage ditches, which reduces the work efficiency of construction workers. At this time, a temporary drainage device for the primary support section of a tunnel has become the first choice for workers.

[0003] When draining, this type of drainage device is often blocked by granular debris such as slag and gravel in the tunnel, so a filtering device has to be added inside to prevent the drainage device from being blocked. When the existing filtering device is used to clean the filtered debris, the entire drainage device needs to be taken out for cleaning. This cleaning method not only prolongs the working time of the staff, but also reduces the construction efficiency of the construction site and cannot meet the needs of users. For this reason, the utility model provides a temporary drainage device for the initial branch section of a tunnel. Summary of the Invention

[0004] In order to solve the above shortcomings and deficiencies of the prior art, the purpose of the present invention is to provide a temporary drainage device for the initial branch section of a tunnel.

[0019] The beneficial effects of the utility model are:

[0020] 1. Compared with the existing technology, when the debris inside the filter device is full and needs to be cleaned, the filter plate in the filter assembly can be slid out to allow larger debris to enter the filter water tank. Because the filter holes of the filter water tank are larger than the diameter of the filter holes on the filter plate, when the filter plate is taken out, the debris will not enter the drainage device with the water flow. After the debris outside the filter plate enters the filter water tank, the filter water tank is taken out and the debris inside the filter water tank can be cleaned, thereby achieving the need to take out the entire drainage device for cleaning, which not only shortens the working time of the staff, but also improves the construction efficiency of the construction site.

[0021] 2. Compared with the existing technology, a drainage device of the same size is designed according to the size of the drainage ditch, and then the drainage device is placed therein. When the drainage device is placed in the drainage ditch, the two side panels inside the drainage device fit with the two sides of the drainage ditch, and the cross brace between the two side panels will support the side panels to prevent the soil on both sides of the drainage ditch from loosening and causing collapse. In addition, the drainage device can be dragged to the position where drainage is needed again according to the progress of tunnel excavation, thereby eliminating the need for frequent excavation of drainage ditches and improving the work efficiency of construction workers.
