CURB STOP-A KEYHOLE INSTALLED, TEMPORARY STOPPERAND SERVICE SHUTOFF DEVICE

摘要

GTI and Advanced Valve Technologies are developing a mechanical in-line valvernand stopper that can be installed through a small-hole excavation. Developing thisrntechnology will address the costs associated with excavation and restoration forrnmaintaining or repairing gas mains and services. The stopper can be left in place and bernutilized in the future such as a curb valve on services. The expenses involved withrnstopping, repairing and reinstating a gas main or service are high due to the labor andrncosts associated with the number of excavations required. Utilizing line stoppingrntechniques through a keyhole minimizes excavation and restoration square footage. Byrnhaving crews performing this everyday, vital function, local distribution companies willrnrealize the saving accrued by this newly developed technique in substantially minimizingrnthe costs in restoration of pavement and landscaping. In addition, the operationsrnpersonnel will be have the ability to sectionalize the distribution system in the future, ifrnnecessary.
