[0030] Traditional cofferdam structures are mostly constructed of earth and stone materials, which have problems such as long construction periods, high material consumption, difficulty in dismantling, and difficulty in recycling. Therefore, the development of a cofferdam structure that is easy to splice, has a short construction time, and is easy to disassemble and reuse is of great practical significance.

[0031] Therefore, the design concept of this application is to design a cofferdam that is easy to assemble, reduces construction time, is easy to disassemble, and is conducive to reuse.

[0032] like Figure 1-3 As shown, the present application provides a splicable cofferdam for construction in shallow waters, comprising a plurality of interconnected cofferdam unit blocks 1 and a waterproof layer covering the outside of the cofferdam unit blocks 1. Adjacent cofferdam unit blocks 1 are detachably connected by connectors, wherein the connectors comprise connector I2 and connector II3 detachably connected to connector I2, and a clamping mechanism is provided between connector I2 and connector II3.

[0033] The present application is mainly composed of a plurality of cofferdam unit blocks 1, each of which has a connection interface that matches the connector. The cofferdam unit block 1 is a shell made of steel, reinforced plastic or composite materials. Each cofferdam unit block 1 can be independently manufactured and transported to the site and then quickly spliced ​​and installed. The cofferdam unit blocks 1 are fastened together by connectors, which can quickly and accurately complete the splicing operation between the cofferdam unit blocks 1 without requiring a lot of manpower and material resources, significantly shortening the construction period. The cofferdam structure is stable and reliable, easy to disassemble and reuse, and the connectors are made of steel. After the cofferdam is spliced, it can be reinforced as needed, such as adding a support structure, filling sand and gravel, etc.

[0034] The connector I2 includes a short slot 4 and a long slot I5. The short slot 4 is detachably connected to the connector II3, and the long slot I5 is detachably connected to one end of the cofferdam unit block 1.

[0035] When in use, the short slot 4 is plugged into the connector II 3 , and the long slot I 5 is plugged into one end of the cofferdam unit block 1 .

[0036] The connector II3 includes a short plug-in block 6 and a long slot II7. The short plug-in block 6 is detachably connected to the short slot 4, and the long slot II7 is detachably connected to the other end of the cofferdam unit block 1.

[0037] When in use, the short plug block 6 is plugged into the short slot 4, and the long slot II 7 is plugged into the other end of the cofferdam unit block 1.

[0038] Wherein, long plug blocks 8 are respectively provided at the left and right ends of the cofferdam unit block 1, and the long plug blocks 8 at the left and right ends of the cofferdam unit block 1 are detachably connected to the long slots I5 and the long slots II7 respectively.

[0039] When in use, the long plug blocks 8 at the left and right ends of the cofferdam unit block 1 are respectively plugged into the long slots I5 and the long slots II7.

[0040] Among them, a small plug block 11 is respectively provided at the end of the long slot I 5 and the end of the long slot II 7 , and a small slot 12 detachably connected to the small plug block 11 is provided at the end of the long plug block 8 .

[0041] The design of the small insert block 11 and the small slot 12 further strengthens the connection between the long insert block 8 and the long slot I 5 and the long slot II 7 respectively.

[0042] A pressing mechanism is provided in the short slot 4 , and the pressing mechanism includes a spring 9 connected to the bottom wall of the short slot 4 . The spring 9 is connected to a pressing plate 10 , and the pressing plate 10 abuts against the short insert block 6 .

[0043] When in use, press the spring 9, then insert the short plug 6 into the short slot 4, release the spring 9, and the pressure plate 10 presses tightly against the short plug 6, so that it fits tightly with the inner wall of the short slot 4, strengthening the connection between the short plug 6 and the short slot 4.

[0044] Among them, the waterproof layer adopts waterproof cloth. After the cofferdam is spliced, the waterproof cloth is covered on the outside of the cofferdam to effectively prevent water leakage and better ensure the overall water-retaining performance of the cofferdam. During actual installation, sealing gaskets can be installed on the connecting surfaces of the cofferdam unit block 1, connector I2 and connector II3 respectively, or sealant can be applied before connection, so as to improve the sealing of the cofferdam itself and improve the waterproof performance of the cofferdam itself.

[0045] A water injection port 13 is provided on the upper part of the cofferdam unit block 1. The water injection port 13 is used to inject water into the cofferdam when needed to increase its stability and water retaining capacity, which is conducive to more stable installation of the cofferdam. When drainage is required, a suction pipe can be placed into the cofferdam unit block 1 through the water injection port 13, and the water can be pumped out with a water pump.

[0046] The cofferdam structure is composed of multiple prefabricated units. Each unit is designed to be standardized and modular, which is convenient for transportation, installation and disassembly. The units are quickly and stably connected through connectors to form a complete cofferdam system. After the construction is completed, the units can be quickly disassembled through the connectors and can be reused, which greatly reduces the project cost.
