摘要
在某泵站的深基坑支护工程中,针对其地质条件复杂、地层种类比较多、各类地层中含砂砾的地层较多、地下水位较浅的特点,采用Φ1000mm钻(冲)孔桩/桩间三管旋喷桩止水/Φ600mm钢管支撑的支护技术进行施工。开挖结果表明,该方案止水效果好、工期较短,实施效果良好。
In the support project of deep pit in a pumping station, aimed at the characteristics of complicated geological conditions, various strata containing gravel and shallow water table, the support technologies of 1000 mm drilling （wash） bore pile/three rotary jets grouting pile for stopping water/600 mm steel pipe support were adopted. The excavation results show that the project has good effect of stopping water, short construction period and good results.
