钻孔粘土桩帷幕截渗工艺是利用机钻按序成孔,采用有效导料管,止水盘向孔内回填粘土并分层去实成桩,以桩桩相割的连接方式在透水地基内形成粘土墙.从而起到截渗的目的.该工艺材料是利用廉价的粘性土,方法安全,工艺简便易于掌握,较其他截渗方法投资省,工期短,尤其潜水流量大,疏干排水困难的地基防渗工程,其优越性更加突出.该工艺经在泗水县黄阴集拦河闸工程中应用,经济效益非常显著,截渗效果达到设计要求.
Drilling clay pile curtain seepage process is the use of machine drill into holes in sequence, the use of effective guide tube, the water tray back to the hole filled with clay and layered into a real pile, split pile connection by way of the permeable foundation Clay wall formed within. Thus play the purpose of impermeable. The process material is the use of cheap cohesive soil, the method is safe, the process is simple and easy to grasp, compared with other cut-off method of investment, short construction period, especially submerged flow, drainage dredging foundation impervious project, its superiority is more prominent. The process was applied in Huangyijianjianjianhe sluice project in Sishui County, the economic benefit is very significant, and the effect of the seepage cutoff meets the design requirements.
