Description

Technical Field

[0001] This utility model relates to a rapid deployment temporary cofferdam structure device for river construction, belonging to the field of cofferdam technology. Background Technology

[0002] A cofferdam is a temporary retaining structure built in water conservancy projects to construct permanent water facilities. Its function is to prevent water and soil from entering the construction site of the structure, so as to facilitate drainage, excavation of the foundation pit, and construction of the structure within the cofferdam.

[0003] Chinese Patent Publication No. CN 221798485 U discloses a temporary cofferdam device for construction, relating to the field of cofferdam technology. This temporary cofferdam device includes four cofferdam panels, which are sequentially spliced ​​end-to-end. Each cofferdam panel has a dovetail strip installed at one end and a dovetail groove at the other end that mates with the dovetail strip. Two opposing cofferdam panels each have two limiting grooves on their inner sides. This temporary cofferdam device, by using dovetail strips and dovetail grooves at both ends of the cofferdam panels, allows for rapid assembly of the cofferdam panels without the need for screws, facilitating assembly. Furthermore, by incorporating adjusting components, cross plates, and connecting plates inside the cofferdam panels, it allows for the rapid use of insertion rods, enabling all rods to be installed quickly and uniformly into the riverbed soil without the need for repeated tightening operations. This simplifies operation, improves efficiency, and is beneficial for practical application and operation.

[0004] During use, the fixing rod needs to be manually rotated to insert into the soil to secure the protective box. However, when used on hard soil, a lot of force is required to insert the fixing rod, which is inconvenient for staff to operate.

[0005] To address this, a rapidly deployable temporary cofferdam structure for river construction is proposed. Utility Model Content
