Foam concrete backfilling method suitable for limited operation space
The invention relates to the technical field of concrete backfilling, in particular to a foam concrete backfilling method suitable for a limited operation space, which comprises the following steps: S1, carrying out base layer treatment on a to-be-backfilled area; s2, backfilling control is conducted on the to-be-backfilled area; s3, foam concrete for backfilling is prepared; the foam concrete comprises a foaming agent, a water reducing agent, water and cement; s4, the foam concrete is conveyed to a to-be-backfilled area; s5, foam concrete is poured in the backfill area in a layered mode; s6, concrete curing is conducted on the backfill area; the concrete curing comprises the steps of covering the solidified concrete with geotechnical cloth and regularly sprinkling water to preserve moisture. Foam concrete is adopted for backfilling the foundation pit in a limited operation space, and compared with a traditional foundation pit backfilling technology, the quality and efficiency are improved, and the manufacturing cost is greatly saved.
本发明涉及混凝土回填技术领域，尤其涉及一种适用于有限作业空间的泡沫混凝土回填方法，包括以下步骤：S1，对待回填区进行基层处理；S2，对待回填区进行回填控制；S3，配制回填用的泡沫混凝土；所述泡沫混凝土包括发泡剂、减水剂、水和水泥；S4，将泡沫混凝土输送至待回填区；S5，在回填区分层浇筑泡沫混凝土；S6，对回填区进行进行混凝土养护；所述混凝土养护包括对已经凝固混凝土进行土工布覆盖和定期洒水保湿。本发明在有限作业空间中采用泡沫混凝土对基坑回填，相较于传统基坑回填土工艺，不仅提质增效，而且大幅节约造价。
