NON-EXCAVATION TYPE CONSTRUCTION METHOD FOR LAYING PIPES

摘要

PURPOSE: A non-excavation type construction method for laying pipes is provided to prevent a pipe path from going around abnormally, thereby reducing construction cost and time. CONSTITUTION: A power head part is installed at the end of an extended pipe to be laid underground so as to excavate earthy materials such as an earth and sand, and stone. A discharge device transfers the earthy materials crushed with the power head part out of the pit with compressed air. A casing pipe is installed at the earth and sand region, and then a main pipe is installed at an inner portion of the casing pipe. The main pipe is installed at an empty wall at the stone region.
