Ta
k
平面尺寸为Φ50m的圆池，地上224m，地下276～726m，拟采用无粘结预应力结构，壁板砼标号为C40，用Φ400mm的沉管灌注桩抗浮，由于场地开阔且基底下为③1层粉质粘土，基坑可按一定的坡
度进行放坡开挖，但基底已接近④层土，该层为细砂，含水量丰富，渗水性强，且具承压性，施工时务必采取可靠的降水措施，谨防产生涌砂现象。

f平面尺寸约25m35m，此构筑物分为三部分：粗格栅，进水提升泵池，设备机房。粗格栅，进水提升泵池为地下式水池，深约8米，钢
筋砼结构。在粗格栅与进水提升泵池间设伸缩缝一道。设备机房
9m32m为钢筋砼框架结构，筏板基础。构筑物自重可以满足抗浮要求，构筑物主要以③1层粉质粘土为持力层。基坑采用放坡开挖，并
应采取有效降水措施。
