Comprehensive tamping construction method for backfilling solid waste mixed soil
The invention discloses a comprehensive tamping construction method for backfilling solid waste mixed soil, and relates to backfilling construction of a foundation pit of constructional engineering. According to the method, saturated clay and graded building slag are evenly mixed according to a certain proportion to form solid waste mixed soil to serve as foundation pit backfill filler, backfill construction is conducted through the comprehensive tamping construction technology of layered rolling and overall reinforcing tamping, and the requirement that the bearing capacity of a composite foundation is 180 kpa according to the design requirement is met and larger than that of the composite foundation; the liquefied soft plastic soil and the building slag are recycled, so that the engineering quality is ensured, the engineering cost is reduced, the ecological environment is prevented from being damaged, the resource consumption is reduced, and the national dual-carbon strategic target is responded.
本发明为一种固废拌合土回填综合夯压施工方法，涉及建筑工程基坑的回填施工。本发明方法是按照一定比例将饱和黏土与级配建渣进行均匀拌合形成固废拌合土作为基坑回填填料，采取分层碾压和整体补强夯实的综合夯压施工工艺进行回填施工，满足并大于了设计要求的复合地基承载力180kpa的要求，实现了液化软塑土和建渣回收再利用，即保证了工程质量，又降低了工程成本，避免了对生态环境造成破坏，减少了资源消耗，响应了国家“双碳”战略目标。
