Abstract

This design has completed the design of the first gate dam hydropower station in the estuary. The design focuses on the design of the first dam station layout, Xie Hongzha and discharge structure of the river hydropower. Firstly, the Qiang River hydropower station first sluice dam project and related building classification. Secondly, according to the engineering geological conditions and topography and other factors, and on the basis of “design specification” sluice layout first sluice dam project are. Finally, to release flood waters gate and discharge structure design; main contents include chamber structure layout, the anti sliding stability calculation, the ground stress calculation, lock floor reinforcement calculation, the energy dissipation calculation etc.. The design requires skilled use of relevant expertise learned by looking to collect the required design parameters and data, and under the guidance of teachers to complete all design elements independently.

Key words: Qianghekou Hydropower Station; Department head dam; Chamber stability; Bottom reinforcement
