摘要
以国防道雨水泵站的深基坑支护止水工程为背景,从钻孔灌注桩和高压旋喷桩的支护止水原理、工艺流程、施工要点等方面阐述了钻孔灌注桩结合高压旋喷桩隔水帷幕在深基坑支护止水工程中的应用。经实践,工程取得了较好的实施效果,证明相关技术措施能够有效地降低深基坑施工引起的周围变形,为同类工程提供了参考和经验。
Taking the deep foundation pit support and water-stop project of the National Defense Road rainwater pumping station as the background,this paper expounds the application of deep foundation pit support and water stop technology of bored piles combined with water curtain of high pressure rotary jet grouting pile in municipal engineering from the aspects of supporting and water stop principle,technological process and construction key points.It is proved that the relevant technical measures can effectively reduce the surrounding deformation caused by deep foundation pit construction,which provides reference and experience for similar projects.
