[0002] In the construction of concrete structures, it is inevitable to install structural casings in the concrete structures to meet the needs of process construction. For example, components such as pipelines and drainage wells that need to be temporarily crossed need to be passed through the casing. After the passing components are used, the casings of existing concrete structures are generally formed by pre-piercing pipes during pouring. On the one hand, before use, the casing is not convenient for sealing and waterproofing; on the other hand, after use, the casing needs to be sealed. Due to the straight penetration structure of the casing, it can generally only be sealed by filling the casing with sealing materials, which has poor sealing and is prone to leakage; in addition, during the casing sealing process, it is necessary to support the formwork at the bottom of the casing, and the construction operation is relatively cumbersome and the construction cost is high; in addition, after the sealing is completed, the casing is often directly exposed to the surface of the concrete structure, which is easily corroded by external air, water, soil and other substances, thereby reducing the durability of the casing and easily affecting the structural safety of the sealed part.
