[0023] The following will further describe the present utility model in detail according to the drawings and embodiments.

[0024] In this specification, the orientation terms such as up, down, left, right, front, back, front side, back side, top, bottom, etc. mentioned or possibly mentioned are defined with respect to the structures shown in the respective drawings. The terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component. They are relative concepts and may therefore change accordingly depending on their different positions and different usage states. Therefore, these or other orientation terms should not be construed as restrictive terms.

[0025] This embodiment provides a water retaining cofferdam, referring to Figures 1 to 3, including a cofferdam body 1 formed by sequentially connecting a plurality of water retaining plates 11 and a support structure 2 arranged outside the cofferdam body 1. The support structure 2 surrounds the outside of the cofferdam body 1, and a first support member 3 is provided between the support structure 2 and each of the plurality of water retaining plates 11. The first support member 3 is connected to the outside of the water retaining plate 11 to ensure that the water retaining plate 11 can remain stable when subjected to external forces, thereby improving the stability of the cofferdam body 1.

[0026] Specifically, the support structure 2 includes a plurality of fixed rods 21 that are spaced apart and vertically arranged. The plurality of fixed rods 21 are evenly distributed outside the cofferdam body 1, and a cross bar 22 is connected between adjacent fixed rods 21. One end of the first support member 3 is connected to the water retaining plate 11, and the other end is connected to the cross bar 22. In this structure, the plurality of fixed rods 21 can be formed into a whole through the plurality of cross bars 22, which can effectively disperse and resist external forces and has strong stability, thereby improving the stability of the cofferdam body 1.

[0027] Furthermore, the first support member 3 is detachably connected to both the water retaining plate 11 and the cross bar 22, which is convenient for the demolition of the cofferdam body 1 and the support structure 2 after the construction is completed. Specifically, an installation plate 5 is fixedly provided at one end of the first support member 3 close to the water retaining plate 11, and a plurality of installation holes 51 are opened on the installation plate 5. During installation, the installation plate 5 can be firmly installed on the water retaining plate 11 through components such as bolts and screws, thereby fixing the first support member 3 on the water retaining plate 11. This is not only convenient for disassembly and assembly, but also the connection between the first support member 3 and the water retaining plate 11 is relatively firm. At the same time, a first connection hole is opened on the first support member 3. Correspondingly, a second connection hole is opened on the cross bar 22. When fixing the first support member 3 and the cross bar 22, the first support member 3 is placed on the cross bar 22, and the two can be fixed together by a fastener 6 passing through the first connection hole and the second connection hole. This method can not only achieve the stable connection of the first support member 3 and the cross bar 22, but also achieve the rapid disassembly and assembly of the two.

[0028] At the same time, the first support member 3 is arranged perpendicular to the water retaining plate 11. The vertically arranged first support member 3 can bear a greater load and can effectively disperse and transfer the load from the water retaining plate 11, making the connection between the water retaining plate 11 and the cross bar 22 more reliable.

[0029] Furthermore, a plurality of horizontally arranged second support members 4 are arranged inside the cofferdam body 1. The second support members 4 are fixedly connected between two adjacent water retaining plates 11, that is, the second support members 4 provide a firm connection for two adjacent water retaining plates 11, which helps to improve the stability of the overall structure of the cofferdam body 1.

[0030] In this embodiment, the width of the bottom of the water baffle 11 gradually decreases downward, that is, the bottom of the water baffle 11 is conical, which facilitates the operator to insert the water baffle 11 into the construction site, can increase the contact surface between the cofferdam body 1 and the construction site, and helps to improve the stability of the cofferdam body 1.

[0031] Meanwhile, in order to prevent water flow from entering the cofferdam body 1 through the connection gap between two water baffles 11, a water stop strip is arranged between adjacent water baffles 11 to prevent external water flow from entering the cofferdam body 1 and affecting the construction. The water stop strip can be made of materials such as rubber and plastic.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
