AI Technical Summary
The existing steel casing is too long and cannot be disassembled in a modular manner, which makes transportation and use inconvenient and reduces construction flexibility.
A steel sleeve with easy-to-assemble and disassemble components was designed. Modular splicing is achieved through structures such as fixing blocks, positioning grooves and threaded rods. Protective coatings are applied to the inner and outer walls of the sleeve to improve corrosion resistance.
It enables modular disassembly and rapid assembly of steel casing, improving construction flexibility, and extends the service life of the casing through a protective coating.
