Description

Technical Field

[0001] The utility model relates to the technical field of tunnel anti-seepage, in particular to a tunnel anti-seepage device. Background Art

[0002] Tunnels are often dug through mountains to build closed water channels for water delivery or flood discharge in water conservancy projects. They are called hydraulic tunnels. Tunnels are not put into use directly after excavation. Construction units need to take a series of anti-seepage measures for tunnels. The existing anti-seepage measures mainly involve spraying anti-seepage coatings. Currently, most construction sites use manual spraying, which is very inefficient and time-consuming.

[0003] The technical solution disclosed in the Chinese patent with publication number CN117287226A sprays the coating on the cave wall surface through a spraying structure. Since the cave wall surface is in an arc shape, the spraying angle of the spraying structure needs to be changed. The rotating disk can be driven to rotate to change the angles of the telescopic structure, the support plate and the spraying structure, thereby spraying the arc-shaped cave wall surface, making the spraying of the cave wall surface more uniform. The output end of the electric push rod is driven to push the limit block to be inserted into the limit hole corresponding to the horizontal position of the rotating disk, so as to avoid the rotating disk from rotating due to the output end of the driving motor, causing the rotating disk to rotate, changing the spraying angle of the spraying structure, affecting the spraying of the protective coating on the cave wall surface, and improving the stability during use.

[0004] However, the device still has some shortcomings: when the device moves in the tunnel, its centering is difficult to control, and the distance between the nozzle output port and the inner wall of the tunnel is different, resulting in uneven paint spraying. Utility Model Content
