AI Technical Summary
In the design of diversion cofferdams, due to the compact layout of hydraulic buildings, the layout site of the temporary waterproof cofferdam is limited, and the upstream slope foot is close to the drainage building, which causes the river water flow to penetrate into the cofferdam and cannot be discovered and dealt with in time, resulting in the upstream slope foot of the cofferdam being easily damaged by erosion and damage, affecting the waterproof effect.
A temporary waterproof cofferdam structure with rib belts is designed, including weirs, slope protection, anti-seepage walls and rib belt networks, and components such as induction boxes, permeability sponges, floats and sliders are installed inside. When water flow penetrates into the induction box, the movement of the floats and sliders will trigger an alarm, issue an alarm, and promptly discover and deal with penetration problems inside the weir.
Through the design of internal rib belts, the problem of river water infiltration into the cofferdam can be discovered and dealt with in a timely manner, preventing the upstream slope foot from being washed and damaged, and improving the use strength and effect of the water-retaining cofferdam.
