Method for plugging through-wall hole
The invention discloses a method for plugging a through-wall hole. The method is characterized in that the through-wall hole is plugged by dry hard cement mortar, the dry hard cement mortar is added with less water during stirring, the shrinkage rate is small after the through-wall hole is plugged, and cracks between the dry hard cement mortar and the hole wall of the through-wall hole and the dry hard cement mortar itself can be prevented, the risk of leakage in later construction is reduced, and meanwhile, by adopting the dry and hard cement mortar, the compactness of concrete in the through-wall hole can be improved, the blocking quality of the through-wall hole is improved, and the quality of project detail nodes is improved.
本发明公开了一种穿墙孔洞的封堵方法，通过干硬性水泥砂浆对穿墙孔洞进行封堵，干硬性水泥砂浆搅拌时加水较少，对穿墙孔洞封堵后收缩率小，能够防止干硬性水泥砂浆与穿墙孔洞的孔壁之间以及干硬性水泥砂浆自身产生裂缝，降低后期施工出现渗漏的风险，同时采用干硬性水泥砂浆能够提高穿墙孔洞内砼密实度，提高穿墙孔洞的封堵质量，提高工程细部节点质量。
