预筑落成法微差下沉施工技术

Construction Technique of the Buildings Gradual Sagging in Pre-build Subsidence

介绍了"预筑落成法"中临时顶托桩、承托体系及上部结构的施工方法,整体下沉作为"预筑落成法"施工过程中的关键环节,重点阐述了建筑物整体微差下沉的施工方法,包括土方开挖、临时顶托桩的破除、下沉操作及注意事项。

This paper introduced the construction method of temporary jacking piles, bearing system, and superstructure in the pre-build subsidence. Overall sinking is the key link in the construction process of pre-build subsidence, therefore, the construction method of building overall differential subsidence was particularly introduced, including earthwork excavation, temporary jacking pile breaking, and the operation method of sinking.
