[0030] As a further implementation of the present scheme, the extrusion cover 3 comprises an extrusion cover body 31, which is located on the same central axis as the sealing sleeve 21, and the outer side of the extrusion cover body 31 is in sliding fit with the inner side of the sealing sleeve 21. A movable groove 32 is formed in the middle of the inner side of the extrusion cover body 31, which is in sliding fit with the outer side of the one-way exhaust pipe 4. A taking groove 33 is formed on the upper surface of the extrusion cover body 31 on both sides, and the vertical cross-sectional shape of the taking groove 33 is "L" shape, which facilitates the construction personnel to easily take out or install the extrusion cover body 31 when needed, and improves the operation convenience.

[0031] As a further implementation of the present scheme, the one-way exhaust pipe 4 is located on the same central axis as the sealing sleeve 21, and the top end of the one-way exhaust pipe 4 is flush with the top end of the sealing sleeve 21. The top end of the inner side of the one-way exhaust pipe 4 is fixedly connected with the exhaust valve 6. The shape of the sealing plug 1 is a conical structure, and the outer side of the sealing plug 1 is provided with a anti-falling groove 5. The number of the anti-falling grooves 5 is four, and the four anti-falling grooves 5 are equally spaced and arranged in a circular arrangement. In cooperation with the filling of the subsequent waterproof sealing glue, the connection stability and waterproof sealing performance between the sealing plug 1 and the screw hole wall can be effectively enhanced.

[0032] As a further implementation of the present scheme, the number of the conveying grooves 23 is matched with the number of the anti-falling grooves 5. The conveying grooves 23 are located above the anti-falling grooves 5, and the conveying grooves 23 and the anti-falling grooves 5 are through from top to bottom. Four connection grooves 25 are formed on the outer surface of the sealing sleeve 21, which extend to the inner side of the sealing sleeve 21. The inner side of the sealing sleeve 21 is connected with the inner side of the sealing sleeve 21 through the inner side of the connection groove 25, which provides a path for the waterproof sealing glue to enter the anti-falling claw mechanism 22, so that the waterproof sealing glue can be evenly filled in each key position, and the waterproof sealing performance is enhanced.

[0033] As a further implementation of the present scheme, a connection groove 228 is formed on the inner wall of the connection box 221 close to one side of the grooved connection pipe 222.

[0034] Workflow: Confirm that the screw hole is clean, free of debris, dust and other substances that affect the sealing effect, prepare the concrete water-facing screw hole waterproof sealing structure and waterproof sealant that matches the screw hole, then knock the sealing plug 1 and the anti-dropping sealing assembly 2 into the screw hole, the conical structure of the sealing plug 1 can play a guiding role, making it easier to find the position when inserting the component into the screw hole, reducing the operation difficulty and improving the installation efficiency. With continuous knocking, the sealing sleeve 21 drives the four anti-dropping claw mechanisms 22 to move synchronously, the elastic claw teeth 223 in the anti-dropping claw mechanism 22 tightly engage with the screw hole wall, playing a fixing role to prevent the sealing sleeve 21 and the sealing plug 1 from shifting during subsequent operations. At the same time, the filling cavity 224 in the elastic claw tooth 223 and the filling hole 225 and the grooved connecting pipe 222 prepare for subsequent waterproof sealant delivery. Since the inside of the sealing sleeve 21 is a hollow structure, it provides space for subsequent waterproof sealant filling. When the sealing sleeve 21 is completely embedded in the screw hole and stops knocking, the extrusion cover body 31 inside the sealing sleeve 21 is removed by taking the slot 33. After filling a certain amount of waterproof sealant inside the sealing sleeve 21, the extrusion cover body 31 is installed again in the sealing sleeve 21. By pressing the top of the extrusion cover body 31, the waterproof sealant in the sealing sleeve 21 is extruded as the extrusion cover body 31 moves downward. Due to the pre-set delivery path delivery hole 24 and the connecting groove 25 in the sealing sleeve 21, the waterproof sealant entering the delivery hole 24 under the action of extrusion force will fill the delivery groove 23 outside the sealing sleeve 21. Then the waterproof sealant flows into the anti-dropping groove 5 of the sealing plug 1 through the delivery groove 23, gradually filling the gap between the sealing sleeve 21, the sealing plug 1 and the screw hole wall. The waterproof sealant entering the connecting groove 25 will enter the connecting groove 228 through the inside of the connecting box 221, and then enter the grooved connecting pipe 222 through the connecting groove 228. The waterproof sealant can flow out from the filling hole 225 on both ends and the middle of the elastic claw tooth 223 of the grooved connecting pipe 222, gradually filling the gap between the anti-dropping claw mechanism 22 and the screw hole wall, thus forming a complete and tight waterproof sealing layer, effectively preventing water from seeping from the screw hole, greatly improving the waterproof sealing performance of the concrete water-facing screw hole. It needs to be supplemented that when the anti-dropping sealing assembly 2 is blocked and the waterproof sealant is injected, the air originally existing in the screw hole needs to be discharged, otherwise it will hinder the smooth filling of the waterproof sealant, causing the sealing to be not dense, affecting the waterproof effect. The one-way air vent 4 and the air vent valve 6 allow air to be discharged outward when the waterproof sealant is injected, ensuring that the waterproof sealant can uniformly and tightly fill the space between the screw hole and the waterproof sealing structure.

[0035] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
