Inner support structure for reinforcing foundation pit support and construction method
The invention provides an inner support structure for reinforcing foundation pit support and a construction method. The inner support structure comprises enclosing purlins and a plurality of steel pipe supports, wherein the enclosing purlins are arranged around a foundation pit, both ends of each steel pipe support are respectively a fixed end and a movable end, and the fixed end and the movable end of each steel pipe support are respectively connected with the enclosing purlins on two opposite sides. According to the inner support structure, only plain concrete is poured into the ends of a steel pipe, so that the self weight of the inner support structure is reduced, and the installation difficulty of the inner support structure is reduced. When the inner support structure is removed, theconnecting position is easy to cut, the plain concrete in the steel pipe can be completely taken out, the integrity of the steel pipe is not damaged, the transportation, recycling and use of the steel pipe are facilitated, and the production cost is reduced.
本发明提供一种用于加强基坑支护的内支撑结构及施工方法，内支撑结构包括围檩和若干钢管支撑，其中，所述围檩设置在所述基坑的周围，所述钢管支撑的两端分别为固定端和活络端，每根所述钢管支撑的所述固定端和所述活络端分别与相对的两侧所述围檩连接。该内支撑结构仅对钢管的端部灌注素混凝土，降低了内支撑结构的自重，减小了内支撑结构的安装难度。内支撑结构拆除时，连接处易切割，钢管内的素混凝土可完全取出，不破坏钢管整体性，有利于钢管的运输、回收和使用，降低了生产成本。
