Backfill construction method for narrow special-shaped space
The invention relates to the technical field of building and infrastructure construction, in particular to a narrow special-shaped space backfilling construction method which comprises the following steps that S1, the outer side wall of a building main body structure is pretreated; s2, the backfill area is cleaned; s3, presetting a flow state solidified soil mixing station on site or adopting finished product premixed flow state solidified soil, formulating a pouring transportation route, and setting a pouring point; s4, layered pouring is conducted on the backfill area; and S5, watering maintenance and film covering maintenance are adopted after single-layer pouring. Earthwork backfilling in the narrow special-shaped space is conducted through the premixed flow state solidified soil, and the technical problems that in the prior art, due to the fact that the special-shaped section cannot be tamped through a machine, the backfilling quality cannot be guaranteed, the construction potential safety hazard in the limited operation space is large, and the low-standard concrete backfilling cost is high are solved. The working face required for backfilling the narrow special-shaped space with the solidified soil is small, multi-section simultaneous construction can be achieved, the construction speed is high, the technological links are few, the construction period is short, and the early strength is high.
本发明涉及建筑及基础设施施工技术领域，尤其是涉及一种狭窄异型空间回填施工方法，包括以下步骤：S1：对构筑物主体结构外侧壁进行预处理；S2：对回填区域进行清理；S3：现场预设流态固化土搅拌站或采用成品预拌流态固化土，制定浇筑运输路线，并设置浇筑点；S4：对回填区域进行分层浇筑；S5：单层浇筑后采用洒水养护和覆膜养护。本发明采用预拌流态固化土进行狭窄异型空间的土方回填，解决了现有技术中异形断面无法用机械进行夯实致回填质量无法保证，有限的作业空间施工安全隐患大，低标混凝土回填成本高的技术问题。固化土回填狭窄异型空间所需工作面小，可多段同时施工，施工速度快，工艺环节少，施工工期短，早期强度较高。
