[0027] like Figure 1 , Figure 2 As shown, the water-stop structure of the present invention comprises a front water-stop 1, a rear water-stop 2 and a partition water-stop 3, wherein the front water-stop 1 is arranged in front of the rear water-stop 2, the front water-stop 1 comprises a front connecting portion 11 located at both sides and a front water-stop portion 12 located in the middle, and the rear water-stop 2 comprises a rear connecting portion 21 located at both sides and a rear water-stop portion 22 located in the middle;

[0028] The partition waterstop 3 includes a partition waterstop portion 31, the front side of the partition waterstop portion 31 is connected to the front waterstop portion 12, the rear side of the partition waterstop portion 31 is connected to the rear waterstop portion 22, and the width of the front side of the partition waterstop portion 31 is equal to the width of the front waterstop portion 12, the width of the rear side of the partition waterstop portion 31 is equal to the width of the rear waterstop portion 22, and the shape and size of the partition waterstop portion 31 are the same as the shape and size of the dam joint 5. This arrangement allows the entire waterstop structure to form a number of cabinets with different elevations after being installed in a concrete dam, and the cabinets are not connected.

[0029] The front waterstop 1 and the rear waterstop 2 constitute two waterstops. In order to facilitate the setting and ensure the use effect, the front waterstop 1 and the rear waterstop 2 are arranged parallel to each other, and the partition waterstop 3 is arranged perpendicular to the front waterstop 1 and the rear waterstop 2.

[0030] In order to further improve the use effect of the water-stop structure, the number of partition water-stops 3 is at least two. Along the height direction of the front water-stop 1 and the rear water-stop 2, all partition water-stops 3 are arranged at intervals from top to bottom, and all partition water-stops 3 are arranged parallel to each other.
