摘要
桩锚支护是近年来新兴的深基坑支护方式,但常规锚杆在饱和软土地区施工中效果不佳。结合胜利油田中心医院综合病房楼基坑支护工程,提出一种适合特殊地质特点的自钻式锚杆施工技术,研究了其施工工艺、操作要点,探讨了监测方式,该工艺实施效果显著,技术先进可行,在多项工程中获得推广应用。
Pile-anchor support is a rising deep excavation support pattern in recent years, but the conventional pile-anchor does not work well in the areas of saturated soft soil. Illustrated by foundation excavation supports of comprehensive inpatient building of Central Hospital of Shengli Oilfield, this paper puts forward a new construction technique of applying self-drilling bolts in special geologic condition with a study on its technology and operating instructions and a further discussion on testing method. This technique is advance, effective and practical and has been applied and promoted in many projects.
