This paper discusses the design and installation of a Grouted-In-Place PVC liner (GIPL) in a large diameter cast-in-place concrete pipe (CIPCP). The Sims Bayou trunk sewer in southeast Houston, Texas consists of several miles of 72" (1.83 m) and 78" (1.98 m) nominally circular concrete structures built about 40-years ago. This paper deals with the structural rehabilitation of approximately 1500 feet (457 m) of 72" (1.83 m) and 8500 feet (2,591 m) of 78" (1.98 m) of this sewer that has deteriorated due to hydrogen sulfide induced corrosion of the inner surfaces of the pipe walls. The design of the GIPL follows classical engineering mechanics for composite reinforced concrete structures. Design examples are given for various levels of deterioration of the host structure.
