1 概述修武县北部太行山区岩层属石灰岩,上部履盖层多为砂砾石、卵石并有少许粘土,且下部石灰岩层也有不同程度的风化,砂砾石、卵石层为强透水层,在该区修建集雨工程,首先应解决渗漏问题,选用复合土工膜防渗技术有效地解决了渗漏问题。根据山区地势,采用岸坡式蓄水池做为山区集雨项目的主要工程类型。2 工程设计
1 Overview The rock formations in the Taihang Mountains in the north of Xiuwu County are limestone. Most of the upper caprocks are gravel, pebbles and a little clay, and the lower limestone layers are also weathered to varying degrees. Gravel and pebble layers are permeable layers. Rainwater project to build, first of all should be to solve the problem of leakage, the selection of composite geomembrane seepage technology effectively solve the leakage problem. According to the topography of the mountainous area, the bank-type reservoir is adopted as the main type of project for rainwater harvesting in mountainous areas. 2 Engineering Design
