Concrete outer wall hole plugging construction method
The invention provides a concrete outer wall hole plugging construction method. The method comprises the following steps that a conical counter bore with the depth P is drilled in a concrete outer wall hole opening with the depth L; the surface of the concrete outer wall hole is soaked for at least one day; a layer of building glue is brushed; micro-expansion waterproof mortar with the thickness M is injected; a polyurethane foaming agent with the thickness N is injected, and that the difference of L, M and N is less than P is met; the micro-expansion waterproof mortar is filled and trowelled; watering maintenance is conducted for at least 7 days; and at least three layers of polyurethane waterproof paint are brushed. By the adoption of the technical scheme, the conical counter bore is drilled in front of the hole opening in advance before plugging, the volumes of the micro-expansion waterproof mortar and the polyurethane foaming agent injected into the outer wall hole are gradually expanded, vibration is conducted in the micro-expansion waterproof mortar injection process, air in the mortar fully escapes, the outer wall hole is filled compactly, the plugging effect is improved, and the method has the advantages that the operation process is simple and convenient, and the anti-seepage effect is good.
本发明提供了一种混凝土外墙孔洞封堵施工方法，包括以下步骤：在深度为L的混凝土外墙孔洞洞口处钻攻一个深度为P的锥形沉孔；浸润混凝土外墙孔洞表面至少一天；涂刷一层建筑胶；注入厚度为M的微膨胀防水砂浆；注入厚度为N的聚氨酯发泡剂，并且满足L‑M‑N
