摘要
掌鸠河引水供水工程具有输水线路长,具备自流供水的水头差及输水线路沿线地形、地质条件复杂等特点。结合输水工艺设计要求和特点,比较多种输水方案后,最终确定了分段控压(低压)自流输水方式,满足了城市供水所需的快速取水、运行灵活的要求,解决了常规设计隧洞压力过高的问题。此外,还简要介绍了超越大的断裂带和超高压倒虹吸设计等关键技术问题的解决措施。
The Zhangjiuhe Water Transfer Project is featured for its long tunnel line, head favourable for free flow and complex geologic and topographic conditions. After comparative studies on the transfer alternatives, it is decided that a sectioned low pressure flow transfer is adopted. It has met the requirement of rapid water supply and flexible operation and avoided the extreme high pressure in the tunnel of a regular design. This paper also describes the solutions to the tunnel to be built on the faulted zones and design of extra-high pressure siphons.
