Construction method for improving backfilling quality of house core
The invention relates to the technical field of building core construction, in particular to a construction method for improving core backfilling quality. The method comprises the following construction steps: calculating the backfilling amount required by a room core; calculating the usage amount of the required expansion material; paying off to plan a backfill material area and an expansion material area; backfilling is conducted; integrally tamping and flattening; floor slab construction; and waiting for the expansion material to expand. By means of the expansion effect of the expansion material, the compactness of the backfill material is improved, the requirement for tamping is lowered, sedimentation and cavities are reduced, then floor collapse and cracks, caused by ground subsidence, of the wall of a house are reduced, the expansion material is evenly expanded during expansion by reasonably planning the backfill material area and the expansion material area, and the expansion effect of the backfill material is improved. The floor slab concrete is firstly paved, and then the expansion exciting agent is injected, so that the expansion time of the expansion material is effectively controlled, and the compactness and the loading capacity of the backfill material are further improved.
本发明涉及建筑房心施工的技术领域，尤其是涉及一种提高房心回填质量的施工方法。本发明施工步骤包括，计算出房心所需回填量；计算出所需膨胀料使用量；放线规划回填料区域和膨胀料区域；进行回填；整体夯实并平整；楼板施工；等待膨胀料进行膨胀。利用膨胀料的膨胀效果，提高回填料的密实度，降低对夯实的要求，减少沉降和空腔的发生，进而减少地板塌陷和房屋墙壁因地面沉降而产生裂痕，通过合理规划回填料区域和膨胀料区域，使得膨胀料在膨胀时均匀膨胀，避免集中膨胀将地面顶裂，先铺设楼板混凝土再注入膨胀激发剂，有效控制膨胀料的膨胀时间，进一步提高回填料的密实度和承压能力。
