[0041] The river dam anti-seepage and water-stopping structure in this embodiment enables the buffer plate 15 to be connected into a whole by setting the fixing plate 16 and the bolt 17, and the impact resistance of the buffer plate 15 is improved by setting the first spring 5 and the second spring 14. The sealing strip 20 with a groove is provided to improve the water seepage in the gap at the connection of the waterproof plate 18. The positioning plate 24 is driven to move by the rotation of the control rod 22, so as to facilitate the installation, positioning or disassembly and replacement of the waterproof plate 18, thereby achieving the effect of optimizing the buffering effect and anti-seepage effect of the anti-seepage and water-stopping structure, facilitating the disassembly and replacement of the waterproof plate 18, and solving the problems that the buffering effect of the existing anti-seepage and water-stopping structure is limited, water may penetrate into the dam body 1 through the gap between adjacent waterproof plates 18, and the disassembly and replacement of the waterproof plate 18 is relatively inconvenient.

[0042] It should be noted that the bottom surface of the positioning plate 24 is an inclined surface, so that when the positioning plate 24 moves forward, it can squeeze and position the waterproof plate 18 under the action of the arc plate 25. A handwheel is provided on the outer circumference of the control rod 22, and a handle is provided on the upper surface of the waterproof plate 18.

[0043] The working principle of the above embodiment is:

[0044] The buffer plate 15 can be connected by the fixing plate 16 and the bolt 17. When the water flow impacts a buffer plate 15, all the slide bars 3 will move and squeeze the first spring 5 through the fixing ring 4. At the same time, the slide bar 3 pushes the ring 11 through the first side plate 7 and the first fixing rod 8, the connecting plate 9, the second fixing rod 13, and the second side plate 12, so that the ring 11 squeezes the second spring 14. Under the joint action of the first spring 5, the second spring 14 and the buffer plate 15 connected as a whole, the buffering effect of the anti-seepage and water-stopping structure is optimized. The sealing strip 20 can block the gap between the waterproof plates 18 to prevent the water flow from penetrating into the dam body 1 through the gap between the waterproof plates 18, thereby optimizing the anti-seepage effect of the anti-seepage and water-stopping structure. When the waterproof plate 18 needs to be replaced, the rotating control rod 22 drives the positioning plate 24 to move backward through the threaded tube 23, cancels the positioning restriction of the positioning plate 24 on the arc plate 25 and the waterproof plate 18, and then the waterproof plate 18 can be pulled out and replaced.
