建筑群密集地区深基坑开挖施工工艺

Construction technology of deep foundation pit excavation in dense buildings area

通过广州某大厦深基坑支护工程的施工,针对该工程中的关键工点,采用了深基坑支护技术中灌注桩、高压旋喷桩与预应力锚杆的联合应用,并采取了特殊支护补强措施,在基坑施工过程中收到良好效果,为在建筑群密集地区修建深基坑提供了可靠的技术参考。

The multiple construction methods of driven cast-in-place pile, high pressure grouting pile and pre-stressed anchor were applied to the key point construction of the edifice deep foundation pit in Guangzhou. And a reinforcement measure reacted to the key point construction. The multiple construction methods and reinforcement measure took a gcod effect for the key point of deep foundation pit. The construction technology provided reliable technical reference for deep foundation pit excavation in dense buildings area.
