丰县东南片由于水源不足,需引郑集河支河水入境,故决定在梁寨建抽水站。站内装有轴流泵5台,设计流量10m~3/s,站后设计水位41.5m,校核水位42.0m,下游枯水位37.5m。站房附近地面高程41.5m,土质自地面至高程30.0m为轻粉质砂壤土,建筑物基础高程位于34.5m。站前进水池宽约5.8m,长约20m,原设计采用四级砂石料滤层;站身后墙排水棱体长18.8m,原设计为三级砂石料滤层,见图1。由于当地砂石料源价格太高,经省水利厅基建处建议改用土工织物作为反滤材料,并委托我院土工所进行试验与设计,由于当时施
Fengxian southeast of the film due to lack of water, need to lead Zheng Ji River water into the country, it decided to build a pumping station in Liangzhai. There are 5 axial flow pumps installed in the station. The designed flow rate is 10m ~ 3 / s. After the station design, the water level is 41.5m, the check water level is 42.0m and the downstream dry level is 37.5m. Ground elevation near the station building 41.5m, soil from the ground to an elevation of 30.0m for light silty loamy soil, the building elevation of 34.5m. Station forward pool width of 5.8m, length of about 20m, the original design of sand and gravel filter layer; standing behind the wall drainage prism length 18.8m, the original design for the three sandstone filter, see Figure 1. Due to the local sandstone source price is too high, proposed by the Infrastructure Department of the Provincial Department of Water Resources to use geotextile as a filter material, and commissioned by our Institute geotechnical test and design, as applied at that time
