Deep foundation pit prestress support-replacement supporting construction method
The invention belongs to the technical field of deep foundation pit supporting, and particularly relates to a deep foundation pit prestress support-replacement supporting construction method. A reinforced concrete force transfer belt is arranged between a main body shear wall and an enclosure pile, a support-replacement steel support and the force transfer belt are arranged in the same axis, and therefore after the shear wall is completely poured, foundation pit refilling is carried out after the force transfer belt reaches design strength. The subsection foundation pit refilling step is omitted, the force transfer belt does not need to be removed, deep foundation pit inner support construction time and investment can be effectively reduced, construction time is saved, and subsequent construction is not affected.
本发明属于深基坑支护技术领域，具体涉及一种深基坑预应力换撑支护的施工方法，主要通过在主体剪力墙与围护桩之间设置钢筋混凝土传力带，并且将换撑钢支撑与传力带设置在同一轴线上，可以使得剪力墙全部浇筑完成后，待传力带达到设计强度再进行基坑回填。目的在于省去了分段式基坑回填的步骤，传力带无需拆除，能有效缩减深基坑内撑施工时间以及减少投资，节省了施工时间，且不影响后续施工。
