Design and Construction of the Joint Node Used in the Deep Foundation by Topdown Construction Method

The top-down construction method is a rapidly developing construction technology used in the deep foundation of high-rise buildings.As the diaphragm wall or the row of piles can act as both the basement wall and the supporting system,and the bracings are the floor slabs underground,the joint nodes of pile and column,column and slab,slab and diaphragm are usually difficult to deal with.In this article,some practical and effective joint nodes are introduced through some practical projects.
