Description

Technical Field

Background Art

[0002] As the construction scale becomes larger and larger, the outline size of the basement reaches N00m*N00m, where N is an integer from 1 to 9, or even N000m*N00m. Some projects are also built in stages, and there are many cases of water leakage in the expansion joints of the basement, which are difficult to repair.
