摘要
结合浦东陆家嘴金融中心基坑工程,针对目前在保证大型基坑安全的前提下,又要经济环保这一难题,提出一种新的施工工艺——"桩墙合一"围护体系及扩底抗拔桩技术。通过对关键技术"桩墙合一"的围护排桩与三轴搅拌桩止水帷幕的围护结构体系以及扩底抗拔桩的研究以及应用,本基坑在开挖后,各项指标均符合设计和规范要求。
Combined with Pudong Lujiazui foundation pit engineering, on the precondition of the safety of large foundation pit at the present time and resolving the problem of environmental protection and economy, this paper proposes a new construction technology ＂pile wall interaction＂ enclosure system and super expanding pedestal pile. Through the research and application of the key technology of ＂the pile-wall interaction＂, three-axis mixing panding pedestal pile, after the excavation of sign and specification requirements. pile water proof curtain retaining structure system and ex- this foundation pit, the indicators are comply with the design and specification requirements.
