AI Technical Summary
Existing sealing devices for joints in prefabricated hydraulic structures suffer from problems such as low positioning accuracy, poor adaptability, low construction efficiency, incomplete filling, and easy cracking and leakage at the joints.
The splicing frame assembly, driven by an airbag ring, expands through a water inlet pipe, which in turn moves the top plate assembly and the snap-fit frame. This enables precise positioning and sealed pouring of the cast splice and the concrete splice component. The multi-framework interwoven structure enhances the seepage prevention and crack resistance of the splice joint.
It achieves efficient and precise positioning and sealing of splice joints, enhances the anti-seepage and crack resistance of splice joints, and ensures the long-term stability and construction efficiency of hydraulic structures.
