The lift-tilting flat steel gate is a hydraulic structure that combines the advantages of vertical lift and tilting gates, primarily used in projects such as hydropower stations and ship locks. Its features include:
Structural Characteristics
During operation, the gate leaf first lifts vertically for a certain distance, then rotates downstream while rising, eventually lying flat on top of the pier. This structure not only reduces the height of the operating platform, facilitating construction and lowering investment, but also enhances seismic resistance.
Application Scenarios
Hydropower Stations: This type of gate has been put into use in projects like the Botang Hydropower Station and Zhangjiagou Gate Station, particularly offering advantages in projects with higher check flood levels.
Ship Locks: Suitable for small and medium-sized ship locks, it addresses the issue of traditional miter gates being unable to withstand bidirectional water heads.
Technical Advantages
Compared to radial gates, the lift-tilting flat steel gate offers shorter piers, simpler structure, and smaller project scale; compared to vertical lift gates, it reduces the requirements for hoisting equipment.
Maintenance Points
Daily maintenance and replacement procedures for wire ropes must be emphasized to ensure the safety and reliability of the hoisting system.
