NEW CONCEPTS FOR PIPELINE EXCAVATION IN ROCK

BECAUSE OF A COMBINATION OF MUNICIPAL INDEBTEDNESS AND LOCAL ROCK CONDITIONS, A TOWN IN OREGON THAT WAS REQUIRED TO INSTALL A SEWER CONTRACTED WITH AN ENGINEERING FIRM TO STUDY THE FEASIBILITY OF APPLYING NEW TECHNOLOGY TO THE PROBLEM. TWO FINDINGS EMERGED THAT MAY BE OF INTEREST TO OTHER CITIES: (1) UNORTHODOX SEWER SYSTEMS SUCH AS VACUUM AND COMMUNITY PRESSURE SYSTEMS WERE FOUND TO BE DEVELOPED TO SUCH AN EXTENT THAT THEY CAN PROBABLY BE DESIGNED WITHOUT MUCH FURTHER RESEARCH. (2) MACHINES AVAILABLE FOR ROCK EXCAVATION IN FIELDS OTHER THAN SEWER CONSTRUCTION SHOW CONSIDERABLE PROMISE. INVESTIGATION IS NEEDED TO DETERMINE WHETHER USE OF ROCK EXCAVATION EQUIPMENT MAY BE AS PRACTICAL AS CONVENTIONAL DRILLING AND BLASTING. NEW TECHNOLOGY APPLICABLE TO SEWER CONSTRUCTION IS REVIEWED IN THE FOLLOWING AREAS: RIPPING, DIGGING, TRENCHING, AUGERING, HYDRAULIC BREAKING, VIBRATORY DRIVING, ROTARY DRILLING, PERCUSSIVE DRILLING, AND JETTING. THE ENGINEERING FIRM IS NOW INVESTIGATING THE COSTS OF THESE VARIOUS APPROACHES.
