Description

Technical Field

[0001] The invention relates to the technical field of building engineering, and in particular to a construction method for pre-embedded reinforcement of a water-stopping sleeve. Background Art

[0002] Waterstop sleeves are common waterproof components in construction projects. They are mainly used for pre-embedded concrete structures. They provide waterproof seals for pipes passing through walls and ground to prevent moisture from penetrating through the pores of the pipes. Waterstop sleeves are widely used in underground projects, tunnels, water supply and drainage pipe systems and other places, and are usually required to have high waterproof performance and structural stability.

[0003] The traditional installation method of water-stop sleeves is usually to bury them by opening reserved holes. The subsequent waterproofing and reinforcement measures are relatively simple, mainly relying on the waterproof performance of the sleeve itself. However, in actual construction, the quality of the concrete structure around the water-stop sleeve, the sealing between the sleeve and the structure, and the reinforcement measures often cannot meet the strict waterproofing requirements, which can easily cause leakage problems between the water-stop sleeve and the surrounding structure, affecting the overall waterproofing effect and structural safety. Therefore, how to ensure the close connection between the water-stop sleeve and the concrete structure, effective waterproof sealing and long-term structural stability has become an important challenge in construction.
