Abstract:

The type and layout of crucial parts of high-head shiplock’s water conveyance system is introduced in this paper. The paper is based on research achievements in China and abroad as well as in the Yangtze River Scientific Research Institute since its founding half a century ago. The basic pattern of dynamically balanced conveyance system which fits different chamber sizes and water heads is introduced. A new idea of solving the lip cavitation of reversed tainter valve is presented, and a new type of dispersed conveyance system with double energy-dissipation systems (internal stilling pool and external dissipation plate) of higher dissipation efficiency is proposed. This paper could offer a reference for researchers and designers in this regard.

Key words: high-head shiplock, water conveyance system, valve segment, diversion outlet, auxiliary discharge culvert
