Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] like Figs. 1 to 3 As shown, the hydraulic construction cofferdam reinforcement structure of this utility model includes a baffle 1, a base plate 2, a support frame, and a ground-gripping structure 3. The baffle 1 is vertically inserted into the ground. The base plate 2 is vertically connected to the lower part of one side of the baffle 1. The support frame is connected between the upper part of one side of the baffle 1 and the upper surface of the base plate 2. The ground-gripping structure 3 is installed through the base plate 2, and its lower part is inserted into the ground. That is, the baffle 1, the base plate 2, and the support frame can form a stable and reliable triangular structure, thereby effectively improving the protection strength of the cofferdam. By setting the ground-gripping structure 3, the ground-gripping performance of the hydraulic construction cofferdam reinforcement structure can be effectively improved, thereby further improving the overall stability and reliability of the structure.

[0030] The ground gripping structure 3 comprises a mounting cylinder 301, a moving piece, a rotating piece and a ground gripping claw 302. The mounting cylinder 301 penetrates through the bottom plate 2 and is fixedly connected with the bottom plate 2. The lower part of the moving piece is in sliding fit with the inner cavity of the mounting cylinder 301, and the upper part of the moving piece extends out of the mounting cylinder 301. The rotating piece is rotatably installed at the upper end of the mounting cylinder 301, and the moving piece is in threaded fit with the rotating piece. The bottom of the mounting cylinder 301 is provided with a ground insertion cone 303, and a through slot 304 is formed in the lower end of the side wall of the mounting cylinder 301. The ground gripping end of the ground gripping claw 302 is arranged outside the through slot 304, and the connecting end of the ground gripping claw 302 is hingedly connected with the bottom of the moving piece through the through slot 304. Since the moving piece is in threaded fit with the rotating piece, and the lower part of the moving piece is in sliding fit with the inner cavity of the mounting cylinder 301, the rotating piece can drive the moving piece to move up and down, and further drive the ground gripping claw 302 to extend or retract.

[0031] In use, the baffle 1 is inserted into the ground at the intended position according to the requirement, until the bottom plate 2 is attached to the ground, and then the ground gripping structure 3 is used to fix the bottom plate 2 on the ground. The support frame can effectively support and reinforce the baffle 1, and the ground gripping structure 3 can effectively improve the ground gripping strength of the bottom plate 2.

[0032] In use, the ground gripping structure 3 is used to insert the lower part of the mounting cylinder 301 into the soil through the ground insertion cone 303, so as to fix the bottom plate 2 on the ground. Then the rotating piece is rotated to drive the moving piece to move downward, so that the ground gripping claw 302 extends out of the through slot 304 and is inserted into the soil, so that the ground gripping effect of the ground gripping structure 3 is better, and the bottom plate 2 is more stable.

[0033] Specifically, the ground gripping claw 302 can be provided according to actual use requirements, and a plurality of ground gripping claws 302 are uniformly arranged along the ring shape of the mounting cylinder 301, and a through slot 304 is arranged corresponding to each ground gripping claw 302. The ground gripping end of the ground gripping claw 302 is in an arrow structure, and the arrow structure is hingedly connected with the bottom of the moving piece through a connecting rod, that is, the connecting end of the ground gripping claw 302 is one end of the connecting rod away from the arrow structure. The connecting rod of the ground gripping claw 302 can freely pass through the through slot 304, so as to facilitate the outward extension of the ground gripping claw 302. Due to the structure and size of the ground gripping claw 302, the arrow structure cannot pass through the through slot 304 and enter the mounting cylinder 301. Instead, when the ground gripping claw 302 is in the retracted state, the arrow structure of the ground gripping claw 302 is just clamped at the through slot 304, so it will not affect the insertion of the mounting cylinder 301 into the soil. In use, the rotating piece is rotated, so that the arrow structure of the ground gripping claw 302 smoothly extends out of the through slot 304 under the downward pressure of the moving piece, and the ground gripping is realized.

[0034] Specifically, the moving part comprises a moving block 305 and a moving rod 306, the moving block 305 is in sliding fit with the inner cavity of the mounting cylinder 301, the lower end of the moving rod 306 is fixedly connected with the moving block 305, the upper end of the moving rod 306 is arranged outside the mounting cylinder 301 through the rotating part, and the moving rod 306 is in threaded fit with the rotating part. That is, the moving rod 306 can be driven to move up and down by rotating the rotating part, and in turn the moving block 305 is driven to slide up and down in the mounting cylinder 301.

[0036] Specifically, the rotating part comprises a rotating cylinder 308 and a plurality of rotating rods 309, the lower part of the outer circumferential surface of the rotating cylinder 308 is connected with the upper end of the mounting cylinder 301 through a bearing, so that the rotating cylinder 308 can freely rotate relative to the upper end of the mounting cylinder 301. The plurality of rotating rods 309 are arranged in a ring shape on the upper end of the outer circumferential surface of the rotating cylinder 308, which facilitates the rotation of the rotating cylinder 308. Wherein, the center of the rotating cylinder 308 is provided with a threaded hole in threaded fit with the moving rod 306, and the rotating cylinder 308 can be driven to rotate by rotating the rotating rod 309, so as to drive the moving rod 306 to move up and down.

[0037] Specifically, a limiting block 310 is fixedly arranged on the side wall of the moving block 305, and a limiting groove extending vertically is arranged on the inner side wall of the mounting cylinder 301, the limiting block 310 is in sliding fit with the limiting groove, so as to limit the moving block 305 to move up and down in the mounting cylinder 301.

[0038] Specifically, the bottom of the moving block 305 is provided with a hinge part 311, and the gripping claw 302 is hingedly connected with the moving block 305 through the hinge part 311, so that when the moving block 305 is pressed down, the gripping claw 302 can be extended outward to grip the ground.

By arranging the first horizontal connecting plate 12, the detachable connection between each inclined rod 11 and the baffle 1 can be realized.

[0040] The support frame further comprises a plurality of horizontal rods 13 corresponding to the inclined rods 11, one end of each horizontal rod 13 is connected and fixed with the second horizontal connecting plate 14, the second horizontal connecting plate 14 is connected and fixed with the baffle 1 through bolts, and the other end of each horizontal rod 13 is connected and fixed with each inclined rod 11 correspondingly. That is, by arranging the second horizontal connecting plate 14, the detachable connection between each horizontal rod 13 and the baffle 1 can be realized, and by arranging a plurality of horizontal rods 13, the support strength of the support frame can be improved.

[0041] The bottom plate 2 is connected and fixed with the third horizontal connecting plate 15 on one side, and the third horizontal connecting plate 15 is connected and fixed with the baffle 1 through bolts. That is, by arranging the third horizontal connecting plate 15, the detachable connection between the bottom plate 2 and the baffle 1 can be realized.

[0042] Specifically, the dovetail groove 101 is arranged on the left side of the baffle 1, and the dovetail protrusion 102 matched with the dovetail groove 101 is arranged on the right side of the baffle 1.
