便于预筑落成法施工的临时顶托混凝土灌注桩设计与应用

Design and Application of Temporary Jacking Concrete Filling Pile Convenient for Construction of Pre-build Subsidence

基于带地下室桩承建筑物的一种全新施工方法——预筑落成法,详细阐述了带载条件下可横向分块、竖向分节的临时顶托混凝土灌注桩的设计过程,介绍了该桩身主要设计原则及相关构造设计,并对临时顶托桩与永久工程桩整体浇筑施工以及最终嵌固连接作相关阐述。

This paper describes the principle of pre-build subsidence method, and the design process of the temporary concrete jacking piles that can be horizontally and vertically partitioned. The main design principles and relevant structure design of pile, the construction and the fixed connection of temporary jacking piles and permanent engineering pile are introduced in detail.
