The width of the vertical baffle is equal to that of the dam body, and the cross section of the abutting block is in an isosceles trapezoid shape. When the first hydraulic telescopic rod is in the first length and the length of the second hydraulic telescopic rod is in the third length, the supporting block is abutted to a plane represented by one waist of the isosceles trapezoid of the abutting block; when the first hydraulic telescopic rod is in the second length, the supporting block abuts against a plane represented by the top edge of the isosceles trapezoid in the abutting block.
