[0024] When constructing the dam 1 of a water conservancy and hydropower project, the worker first moves the outer anti-seepage board 2 downward along the installation groove 102 through the installation block 3 from one side of the dam 1, so that the lower surface of the bottom plate 205 is flush with the bottom of the dam 1. At this time, the top of the installation block 3 is flush with the top of the dam 1. Then, the plug-in component in the fixing component 4 is inserted into the plug-in groove 301, and the actuators of several fixing components 4 are pushed out and inserted into the corresponding fixing grooves 1021, so that the installation block 3 is fixed to the dam 1, and then the remaining anti-seepage boards 2 are spliced ​​in turn, such as the inclined plates 208, The splicing blocks 207 on the vertical plate 201 and the bottom plate 205 are inserted into the splicing grooves 206 on another inclined plate 208, the vertical plate 201 and the bottom plate 205, and the splicing is performed so that the multiple water-proof panels 2 form a whole.

During the splicing process, the polymer water-absorbing resin layers 202 in contact form an integral anti-seepage structure, which plays a role in sealing and anti-seepage; Then the staff horizontally installs the top plate 5 on the dam 1 and the anti-seepage board 2 through the buckle plate 501 and the groove 5041, so that the buckle plate 501 is inserted into the buckle groove 101, and the groove 5041 is sleeved on the top of the vertical plate 201. At this time, the surface of the protective shell 502 is in contact with the side wall of the dam 1, and then the top plate 5 is fixed to the top of the dam 1 and the outer walls of the plurality of vertical plates 201 by bolts. During installation, the pumping pipe 5031 is extended into the space between the dam 1 and the anti-seepage board 2. , installation is completed. During use, when water penetrates the anti-seepage board 2, it will gather in the space. At this time, the liquid detector 302 detects the water and sends a signal to the control center. The control center sends a start signal to the water pump 503 and warns the staff that the anti-seepage board 2 has water seepage. The two water pumps 503 work to pump out the accumulated water in the space through the pumping pipe 5031 and discharge it from the water pipe 5032.

[0026] When fixing the mounting block 3 to the mounting groove 102, the staff uses a crane to lift the plug rod 407 and insert it into the plug groove 301, and move it downward. The moving plug rod 407 drives the truncated cone end 4071 to move downward, and the truncated cone end 4071 contacts the inclined surface 406 of each fixing rod 401, and the downward movement of the plug rod 407 pushes the fixing rod 401 to move, and the inclined surface 406 moves along the side of the truncated cone end 4071, and the outer surface of the plug rod 407 is moved.
