Salinized soil area pipe gallery backfill construction method based on microbial grouting
The invention discloses a salinized soil area pipe gallery backfill construction method based on microbial grouting, and belongs to the field of underground comprehensive pipe gallery construction.The salinized soil area pipe gallery backfill construction method based on microbial grouting comprises the following steps that S1, a pipe gallery foundation pit is cleaned; s2, dismantling a pipe gallery foundation pit support; s3, laying a grouting pipeline; s4, the foundation pit is backfilled, compacted and flattened; wherein the foundation pit is backfilled in a sectional manner; s5, a microbial bacterial solution is injected into the grouting pipeline; and S6, the foundation pit backfill layer is maintained, a roadbed is constructed, the permeability coefficient and the unconfined compressive strength both meet the actual engineering requirements in the mode of grouting through the microbial bacterial liquid, the overall strength of backfill soil in the foundation trench is effectively improved, and the service life of the pipe gallery is prolonged.
本发明公开了一种基于微生物注浆的盐渍土地区管廊回填施工方法，属于地下综合管廊施工领域，一种基于微生物注浆的盐渍土地区管廊回填施工方法，包括以下步骤：S1：管廊基坑清理；S2：管廊基坑支护拆除；S3：注浆管道铺设；S4：基坑回填并压实、碾平；其中，基坑采用分段式回填；S5：向注浆管道内注入微生物菌液；S6：对基坑回填层养护，并施工路基，通过利用微生物菌液注浆的方式，无论是渗透系数还是无侧限抗压强度均满足实际工程需要，有效提升基槽内回填土的整体强度，延长管廊的使用寿命。
