During the construction process of water conservancy projects, it will be affected by ocean tides, which will cause the water level around the foundation pit to fluctuate and affect the cofferdam structure.

[0003] At present, the cofferdam project mainly adopts the methods of steel sheet piles and soil cofferdams. Among them, the steel sheet pile cofferdam is easily affected by tides, and the construction progress is slow and the cost is high. Although the existing soil cofferdam has a low cost, its ability to resist tidal impact is poor. Content of the Utility Model

Flat steel is welded on the periphery of the steel wire mesh. A plurality of the steel wire fences are fixedly connected in sequence along the same direction to form a side frame. Two groups of parallel arranged frames form a main cofferdam frame. Ton-bags are placed closely inside the steel wire fence. Backfill soil is filled between the two groups of ton-bags. The adjacent steel wire fences on the same side are positioned and connected through a connecting component. The tops of the steel wire fences on both sides are fixedly connected through a reinforcing component;

[0006] Among them, the connecting component includes a first iron ring and a first steel pipe. A plurality of concentric first iron rings are welded up and down at the adjacent and close sides of the steel wire fences. A first steel pipe is vertically inserted into a plurality of groups of the first iron rings, and the bottom of the first steel pipe is fixedly inserted into the beach;

[0007] The reinforcing component includes a second iron ring and a second steel pipe. The top of the steel wire fence uses the second steel pipe to conduct tension reinforcement on two rows of the first steel pipes. The horizontal installation height of the second steel pipe is aligned with the elevation of the top of the steel wire fence. First iron rings are welded at both ends of the second steel pipe. The second steel pipe is sleeved and connected with the first steel pipe through the first iron ring. Second iron rings are welded on the outer pipe bodies of the first iron rings at both ends of the second steel pipe. A third steel pipe is inserted into the second iron ring, and the bottom of the third steel pipe is inserted and fixed into the beach.

[0008] As a further solution of the utility model, the inner diameter of the third steel pipe is larger than that of the second steel pipe and the first steel pipe.

[0014] 2. At the same time, by setting the second steel pipe and the third steel pipe as beams and external force columns, they play a role in supporting the cofferdam, further improving the anti-deformation ability of the cofferdam;

[0015] 3. The backfill soil in the center of the cofferdam is silty clay, which significantly improves the anti-seepage ability of the cofferdam and ensures a normal dry construction environment;

[0016] 4. The main framework of the cofferdam is formed by inserting and overlapping steel pipes. The ton bags are convenient to hoist, which is beneficial to accelerating the construction progress and also facilitates the disassembly of the cofferdam in the later stage.
