Self-mixing fluid soil backfilling method
The invention discloses a self-mixing flow-state soil backfilling method, and relates to the field of flow-state soil backfilling, and the method comprises the following steps: S1, backfilling soil into a construction foundation trench, detecting the strength of the soil before backfilling the soil, after the strength of the backfilling soil is detected, if the strength of the backfilling soil does not reach a required compaction coefficient, doping fly ash, cement and a curing agent material into the backfilling soil, mixing and stirring the backfill soil with fly ash, cement and a curing agent to form fluid soil, backfilling the construction foundation trench through liquid soil, and detecting the strength of the solidified liquid soil before backfilling the liquid soil. The problems that various underground pipelines in the collapsible yellow soil area are difficult to backfill, and the compaction coefficient of backfill soil is not easy to guarantee are solved, and the purposes of accelerating the project progress, guaranteeing the project quality and achieving quality guaranteeing and efficiency creating are achieved. And meanwhile, during construction, the material is in a liquid state during cast-in-place, dust pollution is avoided, environmental protection is achieved, and the construction quality is guaranteed.
本发明公开了一种自拌流态土回填方法,涉及到流态土回填领域,包括以下步骤:S1:向施工基槽中回填土,回填土之前先检测土的强度,检测出回填土的强度后,回填土的强度未达到要求的压实系数,需要向回填土中掺入粉煤灰、水泥、固化剂材料,再将回填土与粉煤灰、水泥、固化剂进行混合搅拌从而形成流态土,通过液态土对施工基槽进行回填,在回填液态土之前先检测液态土凝固后的强度。本发明解决湿陷性黄士区域地下各种管道回填十困难,回填土压实系数不易保证问题,实现加快工程进度,保证工程质量,实现保质创效的目的。同时施工时现场浇筑时材料为液态不会产生扬尘污染,实现绿色环保,保证了施工质量。
