Fertilizer groove backfilling construction method based on MICP technology
The invention relates to the technical field of fertilizer groove backfilling, and particularly discloses a fertilizer groove backfilling construction method based on an MICP technology. The invention provides a fertilizer groove backfilling construction method based on an MICP technology. The method comprises the following steps that soil body properties are measured, wherein the maximum dry density rho dmax and the optimal water content w of a soil body are measured; preparing microorganism slurry and cementing liquid; backfill soil is prepared, specifically, the cementing liquid is added into the soil body, and the backfill soil is obtained; backfilling construction is conducted, specifically, backfilling is conducted on the fertilizer groove by 300-400 mm through backfilling soil, then microorganism slurry is sprayed to the surface of the backfilling soil, after the microorganism slurry permeates to the bottom of the backfilling soil, backfilling and spraying of the microorganism slurry continue to be conducted on the fertilizer groove, and the operation is repeated till backfilling of the fertilizer groove is completed. The fertile groove backfilling construction method based on the MICP technology has the advantages of being low in construction cost, simple in construction method, high in backfilling compactness and the like.
本申请涉及肥槽回填技术领域，具体公开了一种基于MICP技术的肥槽回填施工方法。本申请提供的基于MICP技术的肥槽回填施工方法包括以下步骤：土体性质测定：测定土体的最大干密度ρdmax与最优含水量w；制备微生物浆液、胶结液；制备回填土：将胶结液添加至土体中，获得回填土；回填施工：利用回填土对肥槽回填300‑400mm，然后在回填土表面喷洒微生物浆液，待微生物浆液渗透至回填土底部后，继续对肥槽回填、喷洒微生物浆液，重复上述操作，直至肥槽回填完毕。本申请提供的基于MICP技术的肥槽回填施工方法具有施工成本低、施工方法简单、回填密实性高等优点。
