水库移民安置点小型供水工程取水枢纽选用探讨

Selection of Intake Works for Small- sized Water Supply Project at Population Resettlement Site

结合中国山区沟道流量水位变化大,含沙量较大的特点,分析了水库移民安置点小型供水工程取水枢纽——底格栏栅坝和埋藏式渗渠(管)的特点及其适用性。诸多埋藏式渗渠(管)的工程实例表明,该取水方式不仅适合南方山区,而且在西藏、青海等地区具有很好的发展前景。

In combination with the characteristics of large variation of discharge and water level as well as the high sediment in galleys or valleys in mountain areas in China, the characteristics and adaptability of the intake works such as bottom trashrack dam and the buried infiltration gallery （pipe） for the small-sized water supply project at population resettlement site are analyzed. Many engineering practices of the buried infiltration galleries （pipes） represent that this intake mode is not only suitable in the southern mountain areas but also in Tibet, Qinghai, etc where the intake mode is with prosperous development.
