深层搅拌桩内插钢管新方法及其应用

A New Method of Deep Mixing Pile Inserting Steel Pipes and the Application

针对传统加筋深层搅拌桩施工过程中内插钢管施工效率低、成本高、标高垂直度难以控制的现状,依托南京江北泰山保障房片区E地块基坑支护项目,设计了一套简易的深层搅拌桩内插钢管施工新方法。该方法系统制作安装简单,降低了施工难度、提高了效率、降低了成本,为类似工程的施工提供了借鉴。

There are many defects in the traditional reinforced deep mixed piles construction, such as low efficiency in steel pipe inserting operation, high cost and difficult control on elevation height and verticality. A set of new and simple method of deep mixing pile inserting steel pipes was designed for a foundation pit support project in Nanjing, the devices of this sys- tem are simple to manufacture and install, the construction difficulty and cost are reduced and the working efficiency is improved.
