Backfilling method suitable for narrow ultra-deep fertilizer groove of underground complex
The invention relates to the technical field of building construction, in particular to a backfilling method suitable for an underground complex narrow ultra-deep fertilizer groove. The method specifically comprises the following steps: S1, cleaning the bottom surface of a fertilizer tank, and cleaning falling mortar, stone impurities and the like; s2, the selected curing agent and raw material soil are inspected, and after the inspection is qualified, stirring of the flow-state solidified soil can be conducted; s3, the quality of the premixed flow-state solidified soil is inspected; s4, pouring and backfilling the premixed flow-state solidified soil transported to the construction site in a layered manner; and S5, after pouring is completed, covering maintenance is conducted immediately, and the maintenance time is not shorter than 7 d. The premixed flow-state solidified soil adopted by the invention has the advantages of high compactness and high compressive strength, and has the characteristics of volume stability, water stability, impermeability and the like. By applying the backfilling construction method, the backfilling construction quality of the fertilizer groove is ensured, the construction efficiency of backfilling construction is improved, meanwhile, environmental pollution is reduced, and the concept of green construction is met.
本发明涉及建筑施工技术领域，具体涉及一种适用于地下综合体狭窄超深肥槽的回填方法。具体包括以下步骤：S1、对肥槽底面进行清理，将回落的砂浆、石子杂物等清除干净；S2、对所选用的固化剂及原料土进行检验，检验合格后方可进行流态固化土的拌制；S3、检验预拌流态固化土的质量；S4、将运输至施工现场的预拌流态固化土分层浇筑回填；S5、浇筑完成后立即进行覆盖养护，养护时间不少于7d。本发明所采用的预拌流态固化土具有高密实度、高抗压强度的优点，且具有体积稳定性、水稳性和抗渗性等特点。通过应用本发明中的回填施工方法，不仅确保了肥槽回填施工质量，也提高了回填施工的施工效率，同时减少了环境污染，符合绿色施工的理念。
