发明名称 Method and device for lining a sewer pipe
摘要 An assembly for introducing a pipe liner into a sewer pipe includes a launcher defining a passageway through which a resin impregnated pipe liner and bladder tube assembly passes. An inflatable member mounted to the launcher assembly is actuatable between an inflatable condition and a deflated condition. The pipe liner and bladder tube are secured in place by expanding the inflatable member outward against the inner surface of the sewer pipe. Air pressure drives the bladder tube and pipe liner into the sewer pipe and the bladder tube remains in place until the pipe liner hardens.
