[0002] A cofferdam is a temporary retaining structure used during the construction of permanent water conservancy facilities. Its purpose is to prevent water and soil from entering the building site, allowing drainage, excavation, and construction within the cofferdam. It is typically used in hydraulic structures and, unless it is part of a formal structure, is typically dismantled after use.

[0003] The existing earth-rock cofferdams, sack cofferdams, etc. are simple to construct and low in cost, but they are not aesthetically pleasing and difficult to dismantle, making them unsuitable as temporary cofferdams. Steel plate cofferdams are mostly rectangular in shape, and other curved shapes require corresponding curved connecting plates, which is more troublesome. Therefore, in response to this situation, we propose a more convenient and practical steel cofferdam structure to meet the needs of use. Summary of the Invention

[0024] It should be noted that during use, the fixed plate 101 is first placed on the ground, and the sliding plates 108 on both sides of the fixed plate 101 slide out from the fixed plate 101 to the appropriate position, and the insertion rod 109 is inserted into the ground to form an anchor. Then the operator rotates the handle 105 to drive the first screw 103 to rotate, so that the sliding block 104 moves horizontally in the fixed frame 102, driving the support rod 106 to move, and under the action of the connecting frame 4, the fitting angle of the support plate 107 and the ground or structural surface is adjusted to form a triangular support structure to disperse the load.

[0026] It should be noted that during use, when assembling, first insert the snap-in block 202 of the connecting plate 201 into the snap-in groove 302 of the telescopic mechanism 3 to complete the preliminary positioning, and then insert the connecting block 204 into the notches on both sides of the connecting plate 201 as needed, and fix the first plug-in plate 203 to enhance the lateral stability, and finally the fixing block 205 is assembled by rotating the connecting rod 206 to absorb the cofferdam deformation stress, and finally, the mounting block 207 is snap-fitted to the mounting plate 113 of the support mechanism 1 and fixed by the positioning rod 208, and assembled with multiple groups of connecting mechanisms 2 and the mounting plate 113 to form a cofferdam structure, and the connecting mechanism 2 is quickly positioned by the setting of the snap-in block 202 and the snap-in groove 302, and the plug-in structure of the connecting block 204 and the first plug-in plate 203 is coordinated to simplify the assembly process and reduce construction time.

[0027] like Figure 5 As shown, the telescopic mechanism 3 includes a clamping plate 301, a clamping groove 302 is opened on the top of the clamping plate 301, the clamping groove 302 is adapted to the clamping block 202, and support blocks 303 are fixedly connected on both sides of the clamping plate 301. A first rotating plate 304 is rotatably connected to one side of the support block 303. An adjusting plate 305 is rotatably connected to one side of the first rotating plate 304. A bidirectional screw 306 is threadedly connected to the top center of the adjusting plate 305. A rotating screw 306 is fixedly connected to the middle of one side of the bidirectional screw Ring 307, one side of the adjustment plate 305 is rotatably connected to the second rotating plate 308, one side of the second rotating plate 308 is rotatably connected to the fixing frame 309, one side of the fixing frame 309 is fixedly connected to the telescopic plate 310, one side of the telescopic plate 310 is plugged with the second plug-in plate 311, one side of the second plug-in plate 311 is fixedly connected to the steel plate 312, flexible plates 313 are provided on both sides of the steel plate 312, and fixing bolts 314 are installed on both sides of the flexible plate 313, and the fixing bolts 314 pass through the steel plate 312.

[0028] It should be noted that during use, the telescopic plate 310 is first plugged into the second plug-in plate 311 to form a closed cofferdam surface with the steel plate 312 and the flexible plate 313, and then the clamping plate 301 is connected to the connecting mechanism 2 through the clamping groove 302, and then the rotating ring 307 is manually rotated to drive the bidirectional screw 306 to drive the adjustment plate 305 to move and adjust the spacing, so that the first rotating plate 304 and the second rotating plate 308 are expanded or retracted, driving the telescopic plate 310 to extend and retract horizontally. After the adjustment is completed, the fixing bolt 314 locks the steel plate 312 and the flexible plate 313, and the telescopic mechanism 3 realizes the rapid extension and retraction of the telescopic plate 310 to adapt to different working heights.

[0029] During use, first place the fixed plate 101 on the ground and insert the insertion rod 109 into the ground to form an anchor. Then the operator rotates the handle 105 to drive the first screw 103 to rotate, so that the sliding block 104 moves horizontally in the fixed frame 102, driving the support rod 106 to move. Under the action of the connecting frame 4, the fitting angle of the support plate 107 and the ground or structural surface is adjusted to form a triangular support structure to disperse the load. Then the motor at the top of the fixed frame 102 drives the second screw 112 to rotate to move the lifting block 111 up and down, driving the mounting plate 113 to adjust the height. Then, when assembling, the clamping block 202 of the connecting plate 201 is inserted into the clamping groove 302 of the telescopic mechanism 3 to complete the initial positioning. Then, according to the needs, the connecting blocks 204 are inserted into both sides of the connecting plate 201, and the second plug-in plate 311 is fixed to enhance the lateral stability. Finally, the fixing block 205 is assembled by rotating the connecting rod 206 to absorb the deformation stress of the cofferdam. The mounting block 207 is clamped with the mounting plate 113 of the support mechanism 1 and fixed by the positioning rod 208. The cofferdam structure is formed by assembling multiple groups of connecting mechanisms 2 and the mounting plate 113. The telescopic plate 310 is plugged and docked with the second plug-in plate 311 to make the steel plate 312 and the flexible plate 31 3 to form a closed cofferdam surface, then connect the clamping plate 301 to the connecting mechanism 2 through the clamping groove 302, and then manually rotate the rotating ring 307 to drive the bidirectional screw 306 to drive the adjustment plate 305 to move and adjust the spacing, so that the first rotating plate 304 and the second rotating plate 308 can be expanded or retracted, driving the telescopic plate 310 to extend and retract horizontally. After the adjustment is completed, the fixing bolt 314 locks the steel plate 312 and the flexible plate 313. This device can make it possible to assemble a variety of shapes and is easy to assemble, greatly shortening the on-site assembly time.

[0030] It should be noted that when using this equipment to perform cofferdam operations, it is necessary to survey the construction site before performing the cofferdam operations to ensure that the foundation is stable and there is no risk of collapse, and to select the appropriate cofferdam mechanism model and configuration according to the actual situation. When installing the support plate 107, sliding plate 108, and lifting frame 110, it is necessary to ensure that the components are firmly connected to avoid loosening or falling off during use. When adjusting the height of the lifting frame 110, the second screw 112 should be turned slowly to avoid lifting too quickly and causing damage to the equipment or injury to the operator. When connecting the various components, it is necessary to ensure that the clamping block 202, the first plug-in plate 203, and the connecting block 204 are correctly clamped to avoid loose connections that affect the stability of the equipment. When using the telescopic mechanism 3 for fixing, it is necessary to ensure that the clamping plate 301 is correctly clamped in the clamping groove 302, and the bidirectional screw 306 is adjusted into place to avoid loosening of the telescopic mechanism 3 and causing failure of the cofferdam.
