A novel wall-piercing sleeve and a construction method for wall-penetrating hole sealing using the same, wherein the sleeve of the novel wall-piercing sleeve is provided with a stress metal reel, the central axis of which is parallel to the central axis of the sleeve, and the stress metal reel The barrel can be self-adaptive according to the diameter of the equipment pipe, and its outermost end is welded on the inner wall of the sleeve for fixing; in the construction of sealing the hole through the wall, first insert the sleeve into the matching elastic rubber sealing tube , when crossing the wall horizontally, both ends of the spacer can be elongated and kept moving horizontally as a whole, when the sleeve is in the middle of the wall, the elongated spacer can be retracted naturally, and the sleeve is tightly bound to the wall; put the device The pipe passes through the center of the stress metal reel, so that the stress metal reel tightly wraps the equipment pipe, and finally, foam glue is filled between the sleeve and the stress metal reel. On the construction site, the wall bushing can be accurately measured and cut according to the wall thickness, and the elastic rubber sealing tube is used in conjunction with it. The operation is simple and easy, and it can be adapted to various reserved holes and rear openings.
