Construction method for backfilling fertilizer tank by using solidified soil
The invention relates to the technical field of fertilizer tank backfilling, and particularly provides a construction method for backfilling a fertilizer tank by using solidified soil. The construction method comprises the following steps of S1, determining a pouring point for backfilling the fertilizer tank according to distribution conditions of a site road and a raw material soil stacking area;S2, installing a stirring unit; S3, preparing curing agent slurry by mixing cement, a curing agent and water; S5, transporting the raw material soil to raw material screening and metering equipment through a loading machine; S7, stirring the curing agent slurry and the screened raw material soil to a uniform viscous state by the cured soil stirring equipment to form solidified soil; and S8, backfilling the solidified soil into the fertilizer groove from the pouring point. Based on the liquidity characteristic of solidified soil, the problem that in conventional backfilling, a foundation pit fertilizer tank is narrow in space and cannot be tamped for backfilling can be solved, meanwhile, the solidified soil contains cement, has certain impermeability and can prevent runoff of underground water, and therefore the waterproof effect of an underground building is improved.
本发明涉及肥槽回填技术领域，具体提供了一种使用固化土进行肥槽回填的施工方法，包括以下步骤：步骤一、根据场地道路和原料土堆放区域分布情况确定肥槽回填的浇筑点；步骤二、进行搅拌机组的安装；步骤三、通过水泥、固化剂和水的混合制备固化剂浆液；步骤五、将原料土通过装载机运输至原料筛分和计量设备；步骤七、固化土搅拌设备将固化剂浆液和筛分后的原料土搅拌至均匀粘稠状态后形成固化土；步骤八、将固化土由浇筑点回填至肥槽中。基于固化土流动性特性，可以解决常规回填中基坑肥槽空间狭窄，无法夯实的肥槽回填，同时固化土中含有水泥成分，具有一定的抗渗性能，能够防止地下水的径流从而增加地下建筑的防水效果。
