When the support vertical plates 5 are installed, the two pressing blocks 6 can be driven to press against the upper and lower ends of the same side of the side frame 2. The screw rod 8 can also be pressed into the corresponding mosaic groove on the side frame 2 by adjusting the vertical position of the mosaic block 7. After the support vertical plates 5 are installed on the side frames 2, the support cross plates 4 can be installed to fix the support rods 3, so that the support structure formed by the support rods 3, the support cross plates 4 and the support vertical plates 5 can be easily installed and disassembled on the cofferdam body 1, and the assembly efficiency is higher, which solves the problem that the existing cofferdam bodies 1 are all made of The bolt connection or welding method leads to the problem that the disassembly and assembly process is very time-consuming and labor-intensive, which is conducive to shortening the cycle and ensuring the progress of construction. A connecting block 12 is welded and fixed in the middle of the mosaic block 7, and the upper and lower ends of the supporting vertical plate 5 are provided with openings 13 that match the structure of the connecting block 12. The outer end of the connecting block 12 extends to the outside of the supporting vertical plate 5 through the opening 13, and the adjacent end of the outer side of the opening 13 is provided with a threaded block 14 welded and fixed to the supporting vertical plate 5. The screw rod 8 is vertically inserted into the interior of the threaded block 14, and the outer end of the screw 8 is connected to the outer end of the connecting block 12. When the screw rod 8 of this structure rotates inside the threaded block 14, it will push the connecting block 12 to move vertically in the opening 13. When the connecting block 12 moves vertically, the vertical position of the mosaic block 7 can be synchronously adjusted to adjust the vertical position of the mosaic block 7. The interlocking block 7 is smoothly pushed into the corresponding interlocking groove on the side frame 2 to complete the limited installation of the support vertical plate 5.

The side corresponding to the side frame 2 is provided with a plurality of groups of fitting openings, and the fitting openings on the side corresponding to the side frame 2 are consistent with the end structure of the support rod 3. The support rod 3 of this structure can be inserted into the fitting openings of the same group on the side corresponding to the side frame 2 by inserting the upper and lower ends into the fitting openings of the same group on the side corresponding to the side frame 2, so as to improve the convenience of assembly on the cofferdam body 1.

[0019] Working principle: When using the rapid cofferdam structure, first, after the cofferdam body 1 is spliced, several support rods 3 are evenly installed between the side frames 2 through several groups of fittings on the corresponding side of the side frame 2, and then two support vertical plates 5 are placed on both sides of the cofferdam body 1 for installation. When installing the support vertical plates 5, two pressure blocks 6 can be driven to press against the upper and lower ends of the same side of the side frame 2. During the lateral movement of the pressure block 6, the limit block 15 needs to be synchronously slid horizontally into the corresponding limit groove on the outer wall of the side frame 2, and then the screw rod 8 is rotated. When the screw rod 8 rotates inside the threaded block 14, it will push the connecting block 12 to move vertically in the opening 13. The connecting block 12 moves vertically synchronously. Adjust the vertical position of the engaging block 7 until the engaging block 7 is smoothly pushed into the corresponding engaging groove on the side frame 2. At this time, the supporting vertical plates 5 are quickly installed on both sides of the cofferdam body 1, and then the supporting cross plates 4 are placed horizontally in the middle of the cofferdam body 1 and both ends are inserted into the interior of the fixing sleeve 9. When the supporting cross plates 4 are installed horizontally, the engaging groove of the engaging seat 10 can be engaged in the middle of the supporting rod 3, and the upper and lower ends of the engaging seat 10 can be inserted and connected by the pin shaft 11. At this time, the supporting structure formed by the supporting rod 3, the supporting cross plates 4 and the supporting vertical plates 5 can be conveniently installed on the cofferdam body 1, and the assembly efficiency is higher, thereby completing a series of work.
