This construction method requires opening a hole in the outer wall, which involves structural damage and waterproof damage, so the construction location needs to be reinforced and waterproofed.

[0003] In the process of opening holes in the exterior walls of existing basements, the openings will have a significant impact on the bearing capacity, stiffness, seismic resistance and waterproofing of the structural walls. Therefore, certain reinforcement measures must be taken for the structure and compensation for waterproofing must be reconsidered.

[0004] However, in the prior art, due to the large openings in the exterior walls, usually only waterproofing modification is considered without considering reinforcement, resulting in the structure being unable to meet the strength requirements and requiring improvement. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a new wall sleeve structure for the outer wall of the basement of an existing building, which is used to solve the problems of insufficient structural strength and difficulty in waterproofing caused by opening holes in the outer wall of the building basement.
