[0002] The plugging of the through-wall bolt holes in the concrete exterior wall is generally directly plugged with mortar. However, since the through-wall bolt holes in the concrete exterior wall plugged with mortar are prone to form gaps between the hole walls, the waterproof effect is poor and the heat preservation effect is not good.

[0003] After retrieval, in the application document with the patent application number 202120752569.9, a plugging structure for through-wall bolt holes of aluminum alloy formwork is disclosed, including an inner wall and an outer wall. A frustum-shaped screw hole is opened on the outer wall. A waterproof mortar layer is arranged at the outer end port of the screw hole, and an inner JS waterproof coating layer is painted around the screw hole. Foam foaming agent is injected in the middle of the screw hole, and an M15 plastering mortar layer is arranged at the inner end port of the screw hole. A screw hole with a self-finding slope of 2.5% is set, and an inner JS waterproof coating layer is painted around the screw hole to achieve the effects of drainage and self-waterproofing. Moreover, the plugging waterproof mortar layer, foam foaming agent and M15 plastering mortar layer have low construction operation difficulty and are plugged densely.

[0004] The above application document realizes efficient plugging by filling foam foaming agent therein, and the setting of the conical hole structure is used to assist in plugging. However, firstly, although the inner side can achieve drainage and self-waterproofing through the setting of the waterproof coating layer, since the foaming agent is filled by extrusion, the injection amount is not easy to control. Therefore, how to ensure the plugging effect while minimizing the waste of the foaming agent has become an urgent problem to be solved.
