Abstract:
Taking the DN800 water supply pipeline rehabititation project in the Xi’erhuanzhong Road in Fuzhou as an example, a series of laboratory prototype tests are carried out, and then the design method of repair technology for thin-wall stainless steel lining is analyzed theoretically. The advantages such as anti-negative pressure and anti-corrosion ability of the stainless steel lining after repairing are verified. Finally, based on the design requirements, the construction principle and working procedure of trenchless repair technology for stainless-steel lining are analyzed.
