Modularized washing, filtering and purifying construction method for sandy soil in foundation pit excavation
The invention relates to the technical field of foundation pit excavation, and discloses a foundation pit excavation sandy soil modular washing, filtering and purifying construction method which comprises the following steps: screening out stones from sandy soil excavated from a foundation pit, diluting the sandy soil in a cleaning pool to form floating primary slurry and precipitated sand, and discharging the primary slurry into a slurry storage tank; the sand materials are subjected to rolling filtration, fine materials in the sand materials fall off through the drum screen, and coarse materials in the sand materials are discharged through the drum screen; a sand washing machine is used for conducting multiple times of cleaning on the fine materials, fine sand and secondary slurry are formed, the fine sand is discharged to a sand storage area through a dewatering screen, the secondary slurry is discharged into a slurry storage tank, and the primary slurry and the secondary slurry are mixed to form a slurry material; and adding a flocculating agent into the slurry material, conveying the slurry material into a belt filter press, and carrying out filter pressing dehydration to form a filter cake. Therefore, fine sand, dry filter cakes and clean water which can be used on site or directly sold are formed, the whole treatment process is green and environment-friendly, and renewable resources are recycled.
本发明涉及基坑开挖的技术领域，公开了基坑开挖砂质土模块化洗滤净化施工方法，包括将基坑开挖出的砂质土通过筛除石块后，再置于清洗池中稀释，形成浮起的初级泥浆以及沉淀的砂料，初级泥浆排至储浆罐中；将砂料进行滚动过滤，砂料中的细料透过滚筒筛落下，砂料中的粗料由滚筒筛排出；利用洗砂机对细料进行多道清洗，形成细砂以及次级泥浆，细砂通过脱水筛后排至储砂区域，次级泥浆排至储浆罐中，初级泥浆与次级泥浆混合形成泥浆料；往泥浆料中加入絮凝剂，再将泥浆料输送至带式压滤机中，进行压滤脱水，形成滤饼。这样，形成有可供现场使用或直接出售的细砂、干燥的滤饼以及清洁水，整体处理过程绿色、环保，使得再生资源得到了循环利用。
