AI Technical Summary
In existing technologies, the diversion system for ultra-high arch dam construction has problems such as complicated construction, long construction period and high cost in terms of construction, ecological water supply and water storage and release control.
Design a shore tower gate chamber structure for an ecological bypass tunnel of an ultra-high arch dam, which includes a hoisting platform, an arc gate, and a flat gate. A partition wall is installed inside the gate chamber to improve safety, and a ladder is installed inside the tower shaft to facilitate gate operation and inspection.
It simplifies the construction process, reduces project investment, meets the requirements of flood control, ecological water supply and water storage and release, protects the gate from damage, and improves structural safety.
