软式透水管在西霞院泄洪闸消力池的应用

Flexible pervious pipe applied for stilling basin of Xixiayuan hydropower project

西霞院泄洪闸消力池底部岩层具有较强的透水性,因此需在消力池底板下铺设排水管以降低扬压力。软式透水管管体结构合理,过滤性能强,排水效果明显,施工方便,能满足设计需要。

There has strong water permeability at the basal bed of stilling basin for flood gate of Xixiayuan hydropower project. The structure of flexible pervious pipe is rational, with strong filterability and obvious drainage effect. It is convenient for construction, and can meet design requirements.
