In this specification, "in one embodiment" does not mean the same embodiment, nor is it an independent or alternative embodiment that excludes other embodiments.

[0024] Embodiments

[0025] Reference Figs. 1-4 For the embodiments of the present application, the embodiments provide a modular cofferdam device convenient to disassemble and reuse, comprising,

[0026] The baffle 101, the side ear 102 fixedly installed on the side wall of the baffle 101, and the mounting assembly 103 arranged on the surface of the baffle 101; the mounting assembly 103 includes an auxiliary component 103a and a connecting component 103b arranged on the side wall of the baffle 101 for use with the baffle 101.

[0027] Specifically, the baffle 101 and the side ear 102 are made of reinforced framework cast concrete material, which has good water retaining performance and good structural strength.

[0028] The auxiliary component 103a comprises a lifting ring 103a-1 fixedly installed on the top of the baffle 101, a rammer plate 103a-2 fixedly installed on the side wall of the baffle 101, and a plate base 103a-3 fixedly installed on the bottom of the baffle 101, and further comprises a clamping block 103a-4 fixedly installed on one side of the baffle 101 and a clamping tenon 103a-5 fixedly installed on the other side of the baffle 101, the rammer plate 103a-2 is arranged on the side wall of the baffle 101 close to the bottom, and the clamping tenon 103a-5 and the clamping block 103a-4 are symmetrically arranged in the middle of the baffle 101.

[0029] Further, the lifting ring 103a-1 is arranged to facilitate the installation and removal of the cofferdam, the rammer plate 103a-2 is arranged to facilitate the use of a rammer to drive the plate base 103a-3 of the baffle 101 into the ground, thereby fixing the baffle 101, and the clamping block 103a-4 and the clamping tenon 103a-5 are arranged to facilitate the installation and removal of the cofferdam, while increasing the strength of the connection between the cofferdams.

[0030] The connecting component 103b comprises a connecting lug 103b-1 fixedly installed on the side wall of the baffle 101, a sealing strip 103b-2 fixedly installed on the inner wall of the connecting lug 103b-1, a guide rail 103b-3 fixedly installed in the inner cavity of the connecting lug 103b-1, and a top block 103b-4 slidingly connected to the outer surface of the guide rail 103b-3.

[0031] Preferably, the sealing strip 103b-2 is made of rubber material, and after the cofferdams are connected, the extrusion between the cofferdams will cause the sealing strip 103b-2 to deform, and the deformed position will fill the gap between the cofferdams, thereby improving the sealing performance of the connection.

[0032] The connecting component 103b further comprises a lead screw 103b-5 connected to the side wall of the top block 103b-4 through a bearing, a fixed seat 103b-6 threadedly connected to the outer surface of the lead screw 103b-5, and an adjusting nut 103b-7 fixedly installed on the end of the lead screw 103b-5.

[0033] It should be noted that the side wall of the fixed seat 103b-6 is fixedly connected to the side wall of the baffle 101, and the lead screw 103b-5 cooperates with the top block 103b-4 to enhance the sealing effect of the connection.

[0034] In use, after the cofferdam is sunk into the water, the rammer is used to ram the ram plate 103a-2, which drives the baffle 101 to move downward, and the plate base 103a-3 is driven into the soil. The side lug 102 of another cofferdam is aligned with the connecting lug 103b-1, the clamping lug 103a-5 is aligned with the clamping slot on the clamping block 103a-4, the cofferdam is placed down, the adjusting nut 103b-7 is actuated, the adjusting nut 103b-7 drives the lead screw 103b-5 to rotate, the lead screw 103b-5 drives the top block 103b-4 to move forward in cooperation with the guide rail 103b-3, the top block 103b-4 drives the side lug 102 to be closely connected with the connecting lug 103b-1, and the sealing strip 103b-2 is deformed under pressure to fill the gap between the connecting lug 103b-1 and the side lug 102. The rammer is used to ram another cofferdam to fix it. After the cofferdam is used to block the construction site, the next step of construction can be carried out. After the construction is completed, the adjusting nut 103b-7 is actuated to drive the lead screw 103b-5 to move the top block 103b-4, and the cofferdam is released from the limit. The hoist is used to connect the lifting ring 103a-1 on the baffle 101 to lift the baffle 101 and transport it to the warehouse or the next construction site.

[0035] In summary, the cofferdam is quickly, efficiently and stably installed and disassembled, greatly improving the construction efficiency and reducing the safety hazards in the construction process. The cooperation between the structures, such as the close connection of the side lug 102 and the connecting lug 103b-1, and the deformation of the sealing strip 103b-2 to fill the gap, ensures the sealing and overall stability of the cofferdam, provides a dry working environment for underwater construction, and facilitates the repeated use and transportation of the cofferdam, reduces the engineering cost, and realizes the recycling of resources.
