[0002] As a temporary water retaining and maintenance structure, the cofferdam is used to prevent water and soil from entering the construction site of the building so as to drain water, excavate foundation pits and build buildings in the cofferdam. It is usually demolished after use. In the cofferdam device for highway bridge construction, the cofferdam must be laid first when the bridge piers are built. Therefore, a highway bridge construction cofferdam device is needed.

[0003] The application number is CN202321154699.8, which discloses a highway bridge construction cofferdam device, which relates to the field of highway bridge construction, including a cofferdam plate, the front surface of the cofferdam plate is welded with a spring, the front surface of the spring is fixedly connected with a positioning rod, the outer wall of the positioning rod is installed with a mesh plate, and the rear surface of the mesh plate is welded with a buffer sleeve. The utility model provides a positioning rod and a mesh plate, and the positioning rod plays a threaded fixing role on the mesh plate. When the device is used, the setting of the mesh plate is convenient for protecting the cofferdam plate, reducing the direct impact of objects on the cofferdam plate, and playing a buffering and protective role on the cofferdam plate, thereby increasing the usability of the device. Through the setting of the tightening rod and the tightening sleeve, the tightening rod plays a threaded fixing role on the tightening sleeve. When the device is used, the setting of the tightening rod is convenient for resisting the bracket, which is convenient for tightening the cofferdam plate and the combined plate, reducing the generation of gaps, and waterproofing.

[0004] The above document discloses a highway bridge construction cofferdam device with the following defects: when the device is used on the ground, when the water level is high and the height of the cofferdam laid on the ground is not enough, it is necessary to raise part of the cofferdam to resist the water flow at the high water level. The structure cannot adjust the height of the cofferdam plate. When encountering such a situation, water enters the foundation pit, affecting the efficiency of subsequent construction.

[0005] It can be seen from this that the existing cofferdam device does not have the function of adjusting the height of the cofferdam plate, and it is necessary to improve the existing deficiencies and provide a function that can adjust the height of the cofferdam plate. Utility Model Content
