Sliplining Large Diameter Pipe

摘要

Most large urban areas depend on interceptor sewers to convey sewage from subdivisions and suburbs to the treatment facilities. Whether the interceptor drains city neighborhoods or a neighboring town's collection system, the pipe is large and usually deep. In an area like Los Angeles, interceptor sewers have been in use for a very long time. The La Cienega Interceptor Sewer was installed in Beverly Hills and Culver City almost 100 years ago. The pipe consists of a profile (non-round) brick tunnel. It was common practice to tile the inside surface of the tunnel with clay tiles made and installed specifically for the profile of the pipe. Over the years the tiles have survived unharmed by hydrogen sulfide gas, however, the mortar that held them in place has all but disappeared, rendering damage to the ceiling of the tunnel in many places. For that reason, the decision was made to slipline the tunnels with a pipe product that will be unaffected by hydrogen sulfide gas.
