Ultra-fast backfilling method for deep foundation pit through support replacement and flow-state solidified soil
The invention relates to a deep foundation pit ultrafast backfilling method for support replacement and fluid solidified soil, and belongs to the technical field of deep foundation pit support replacement. The invention provides an ultrafast backfilling method for a deep foundation pit through support replacement and fluid solidified soil, and solves the problem that support replacement needs to be carried out after backfilling when support construction is carried out in the deep foundation pit in the prior art. The premixed flow-state soil provided by the invention can be pumped at any time during construction of a basement floor, support replacement is realized through self-compaction of the flow-state solidified soil, the traditional procedures of inner support removal, fertilizer groove backfilling and alternate construction of each layer of structure are broken through, separation of support replacement backfilling and construction is realized, labor and material costs are saved, and the construction efficiency is improved. And the construction period can be saved. The fluid-state solidified soil provided by the invention is low in slump and strong in fluidity, can be pumped and can also be poured in a chute, vibration is not needed in the pouring process, and self-compacting backfilling can be realized.
本发明涉及一种换撑及流态固化土的深基坑超快回填方法，属于深基坑换撑技术领域。本发明提供了一种换撑及流态固化土的深基坑超快回填方法，解决了现有技术中在深基坑内支撑施工时面临的换撑问题，需要回填后进行换撑，而本发明提供的超快回填方法是在设置悬挑换撑板时预留开口，可以将本发明提供的预拌流态土在地下室楼板建造的任何时间泵入，通过流态固化土的自密实实现换撑，打破了内支撑拆除、肥槽回填及每层结构施工交替进行的传统工序，实现了换撑回填与建造的分离，不仅节约人工及材料费，还能节省工期。本发明提供的流态固化土坍落度低，流动性强，可泵送也可溜槽浇筑，浇筑过程无需振捣，可实现自密实回填。
