Description

Technical Field

[0001] The utility model relates to the technical field of highway bridge construction, in particular to a highway bridge construction cofferdam device which is convenient to move. Background Technique

[0002] A cofferdam refers to a temporary enclosure structure built during the construction of water conservancy projects for the construction of permanent water conservancy facilities. Its function is to prevent water and soil from entering the construction location of the building, so as to drain water within the cofferdam, excavate the foundation pit, and build the building. In cofferdam construction, the cofferdam is generally composed of multiple groups of baffles spliced together.

[0003] In the prior art, in the patent document with the publication number CN215329971U, a highway bridge construction cofferdam device is proposed, belonging to the technical field of highway bridges. A highway bridge construction cofferdam device includes a baffle. Two grooves are symmetrically arranged in the front and back on the right wall of the baffle. Two bumps are symmetrically fixed on the left wall of the baffle in the front and back. A plurality of clamping rod blocks are screwed on the front wall of the baffle in a uniformly arranged structure. A reinforcing rod is clamped between two adjacent clamping rod blocks. An adjusting jack is hinged to the front wall of the baffle through a hinge seat. The lower end of the adjusting jack is hinged to a fixing plate through a hinge seat. In the utility model, an adjusting jack is fixed on the front wall of the baffle. Through the adjusting jack, the baffle can be supported and fixed, and the inclination angle of the baffle can also be adjusted, so that the baffle is suitable for resisting different strengths, greatly improving the compressive effect of the device.

[0004] In order to solve the problem that when the existing cofferdam encounters a large external force during use, the splicing parts of the baffles are very easy to bend. The prior art is to use a reinforcing rod to be clamped and matched with it, so as to reinforce the splicing parts of the baffles, so that the splicing parts of the baffles are not easy to bend when receiving impact force, greatly improving the stability of the device. However, there will still be a situation where the cofferdam only protects the barrage, which leads to the problem of reducing the practicability of the cofferdam device.
