基坑施工降水基坑施工降水lowering of water level in foundation pit 1 ikeng shigong iiongshui墓坑施工降水(lowering of wate:level infoundation pit)开挖基坑时，为防止地下水的渗入，确保基坑边坡的稳定，创造干燥和安全的施工环境，所采取的人工降低地下水位的措施。人工降低地下水位的主要目的是阻截土中潜流和降低自然水位。由于改变了地下水流方向，减少了对基坑的渗流破坏，从而保证了边坡的稳定，防止坑底隆起和产生流沙.根据土层渗水情况和所需降水深度，基坑降水可采用明渠法、井点法、管井法和辐射井法。 明渠法沿基坑挖出明渠，将水汇集到集水井内，再用序斗或泵等设备将水排出。在沙土中，明渠内可以填入沙砾建成盲沟，以防沙土淤塞沟渠。明渠法降水深度较浅，适用于沙土和粘性土中降水。如果沿荃坑坑壁分段设置明渠，则可以增大降水深度。 井点法用锤击、冲孔或钻孔方法沿墓坑周边作出深达含水层的孔洞，将配有滤水管头的井点管沉入含水层内或用射水法将带有球阀的井点管直接沉入含水层内。井点管与集水管道、抽水设备连接起来，组成井点系统。井点用水泵抽水时称为轻型井点，用真空泵抽水时称为真空井点，借助空气或高速水流的向上高速流动将水抽出时称为喷射井点。井点法适用于诊透一系数为。.05~lom/d的粘土和亚粘土.渗透系数为0.001~0.05m/d的粘土和亚粘土可采用电渗井点法降水。电渗井点法是以擂入土中的井点管作阴极，以插入土中的钢筋棒或铝棒作阳极，通过直流电后，由于直流电场作用，土中水分从阳极流向阴极，再从阴极井点笋一笋终匆…_
