Construction method for building backfill soil in winter
The invention provides a construction method for backfill soil of a building in winter, and belongs to the technical field of building construction.The construction method for the backfill soil of the building in winter comprises the steps that the water content of the backfill soil is collected; according to the requirements of the water content and the compaction degree of the backfill soil, the required backfill soil amount is calculated; the backfill soil is divided into multiple layers for layered backfill; when each layer is backfilled, the resistance of the backfilled soil of the layer is measured by adopting an intermittent discharge method; according to the measured resistance value, the compaction effect of the backfill soil of the layer is judged by referring to a preset resistance-compaction degree corresponding data set; if the compaction effect does not reach the standard, the compaction is continued until the required compaction degree is reached; and the steps are repeated, and all the layers of backfill soil are compacted in sequence. According to the construction method for the backfill soil of the building in winter, the technical problem that in the construction process of the backfill soil of the building in winter, accurate water content detection and compaction degree control cannot be achieved for backfill of frozen soil, and consequently the bearing capacity of the backfill soil is reduced can be solved.
本发明提供了一种冬季建筑回填土施工方法，属于建筑施工技术领域，该冬季建筑回填土施工方法包括：采集回填土的含水量；根据回填土的含水量和压实度要求,计算出所需的回填土量；将回填土量分为多层进行分层回填；在回填每个层时,采用间断放电法测量该层回填土的电阻；根据测量所得电阻值,参照预设的电阻‑压实度对应数据集,判断该层回填土的压实效果；如果压实效果不达标,则继续压实,直至达到要求的压实度；重复上述步骤,依次对各层回填土进行压实。本冬季建筑回填土施工方法能够解决冬季建筑回填土施工过程中，对于冻土的回填不能做到含水量精确检测和压实度控制，导致回填土承载力降低的技术问题。
