Description

Technical Field

[0001] The utility model belongs to the technical field of tunnel engineering, and particularly relates to a dewatering and pressure drainage device for tunnel engineering construction. Background Technique

[0002] The dewatering and pressure drainage device in tunnel engineering construction refers to a series of equipment and systems set up to control and drain the groundwater in the tunnel construction area, and their main functions include:

[0003] 1. Control the groundwater level: Through the dewatering and pressure drainage device, the groundwater level in the construction area can be lowered, reducing the interference of groundwater on tunnel construction, thereby ensuring construction safety.

[0004] 2. Prevent water disasters: In some areas with complex geological conditions or special hydrogeological conditions, groundwater may pose a threat to construction, such as causing water gushing, mud loss, etc. The dewatering device can effectively drain the excess groundwater and prevent these water disaster problems.

[0034] Embodiment 2

[0035] Please refer to Figures 1-5 , on the basis of Embodiment 1, the connecting rod mechanism includes a first connecting rod 18, a second connecting rod 19 and a third connecting rod 20. One end of the first connecting rod 18 is fixedly connected to the moving plate 11.

The water entering the interior of the filter box 2 is filtered by the filter mesh plate 13. The filtered water enters the interior of the drainage box 6 through the water passing port. The water entering the interior of the drainage box 6 will generate water pressure, and the water pressure will push the L-shaped baffle 12 to move. When the L-shaped baffle 12 moves, the water outlet pipe 8 can be opened. After the water outlet pipe 8 is opened, the drainage work can be normally carried out through the first drainage pipe 4 and the second drainage pipe 5;

[0038] During the process of the water pressure pushing the L-shaped baffle 12 to move, the L-shaped baffle 12 will push the moving plate 11 to move.

The filter mesh plate 13 can be automatically cleaned by using the moving cleaning brush plate 17. The present utility model utilizes the driving force generated by the water pressure to achieve the function of automatic cleaning, which is convenient and practical;

[0039] When the filter mesh plate 13 needs to be replaced, only need to rotate the limit plate 22 to release the limit of the sealing plate 14 by the limit plate 22, and then take out the sealing plate 14 and the filter mesh plate 13.
