Application and Laboratory Tests of Stainless Steel Liner for Trenchless Rehabilitation of Water Mains in China
Stainless steel liner, as an emerging method, is being used with increasing frequency for trenchless renovation of damaged water mains in China. In this paper, the application of rehabilitating water mains and laboratory testing of stainless steel liners are described. Practices prove that this new trenchless technology can be effectively and low-costly utilized to renovate damaged water mains and meet the utility owner’s requirements. And considering that there have been little studies on the buckling performance due to external pressure of this new thin-wall structure, the buckling strength of stainless steel liner is studied by laboratory tests. The research shows that the buckling resistance of the DR445 liner is more than 7.25 psi. This conclusion demonstrates that the stainless steel liner meets the requirement in Chinese national standard GB 50332-2002.
