本文详细介绍了逆支正施这一新的施工工艺,并以天津津汇广场工程为例,讲述了逆支正施的施工过程及具体施工方法。在这种方法中,永久结构中的一部分梁板被用作基坑水平支撑。它与连续墙(支护桩)共同工作形成了整个支撑体系,为了利于从基坑向上进行结构施工,在基坑中设置了足够大的空旷空间。
This article describes in detail the new construction process of the reverse branch and the application of the Tianjin Jinhui Square project as an example to describe the construction process and specific construction methods of the reverse branch. In this method, a portion of the beam in the permanent structure is used as a horizontal support for the foundation pit. It works in conjunction with the continuous wall (supporting pile) to form the entire supporting system. In order to facilitate the structural construction from the foundation pit, a large enough open space is set in the foundation pit.
