[0002] In the construction process of underground structures such as water collecting wells, the support of concrete inner formwork is a key link to ensure construction quality. Traditional support methods often use wooden templates or steel templates in combination with steel pipe scaffolding for support, but this approach has many problems. First, wooden templates are prone to deformation due to moisture, affecting the dimensional accuracy and surface quality of the poured concrete structure. Second, the construction and disassembly process of steel pipe scaffolding is tedious, requiring a large amount of labor and time, resulting in low construction efficiency. In addition, traditional support methods also have deficiencies in stability and load-bearing capacity, especially in the construction of large water collecting wells, where formwork deformation and formwork failure are particularly prominent.
