[0002] A cofferdam is a temporary water conservancy facility built in the construction of water conservancy projects to construct permanent water conservancy facilities. It is a temporary retaining structure built to prevent water and soil from entering the construction site of the building, so as to facilitate drainage, excavation of foundation pits, and construction of buildings. It is generally used in hydraulic engineering structures.

[0003] Currently, some existing water conservancy construction cofferdams are used in a manner that is caused by the fact that the cofferdam is composed of multiple steel plates connected together.

[0026] The working principle of the cofferdam for hydraulic construction provided by this utility model is as follows:

[0027] In use, the baffle 51 is first snapped onto the side of the connecting plate 41 through the positioning groove 44. Multiple sets are then assembled and fixed with bolts to form a cylindrical cofferdam from the baffle 51 and the connecting plate 41. Foaming agent is sprayed into the gap between the baffle 51 and the connecting plate 41 to seal the gap. The cofferdam is then hoisted to the construction position, and the connecting plate 41 is inserted into the ground through the bottom-fixed insertion rod 42, ensuring the bottom surface of the connecting plate 41 is flush with the construction surface. Contact is made, and at the same time, the baffle 51 is also extended into the ground through the insert plate 52, so that the baffle 51 and the connecting plate 41 are initially positioned at the construction position. Then, the water in the cofferdam is pumped out, and the support column 1 is driven into the center position on the inner side of the cofferdam. Then, the reinforcing beam 61 is engaged with the inner side of the connecting plate 41 through the limiting groove 43, so that the two ends of the two adjacent reinforcing beams 61 are spliced ​​together, and the connection node of the reinforcing beam 61 is staggered with the connection node of the baffle 51.

The connecting plate 22 is fixed, and then one end of the clamping plate 34 is fixed to the joint 33 at the other end of the double-ended threaded rod 31 by bolts. The clamping plate 34 is then engaged with the connecting node of the reinforcing beam 61 through the connecting groove 35. The clamping plate 34 and the positioning block 62 are then fixedly connected together by bolts, so that the double-ended threaded rod 31 is supported between the support column 1 and the cofferdam, thereby strengthening the cofferdam's compressive strength. This cofferdam has the advantages of facilitating the strengthening of the cofferdam's support and preventing water seepage from affecting the internal construction progress.
