摘　　要：苏里格气田地处毛乌素沙漠深处,地下水位一般在-0.3m左右,地下多为流沙,拟建工程污水处理装置基础底标高都在-5.2m左右,明沟排水易引起流沙坍方,经研究决定采用轻型井点降水方案进行先降水后施工,采用真空泵或射流泵降水。文章对该降水方案的工作原理、施工工艺流程及操作要点、所用的材料与设备等进行了较为详细的论述,并指出该方案具有降水效果好,与深井井点降水方案相比费用较低等优点。Sulige Gas Field is located in deep Maowushu Desert where the water table is about-0.3 m and there are quicksand layers in foundation.Because the base bottom elevation of a planned waste water treatment facility is about-5.2 m,gutter drainage will easily cause collapse.Through investigation,the scheme of light well point drainage using vacuum pump or jet pump is adopted to lower water level prior to construction.The working principle of the light well point drainage method,its construction process and key operation points as well as materials and equipment needed are discussed in this paper.The scheme has the advantages such as good effect of lowering water level and reducing cost compared with the deep well point drainage scheme.
