Abstract

PURPOSE: To feed a lubricant without trouble by arranging a lubricant feed pipe on the inner face of the outer pipe of a long-distance advance steel pipe constituted of both inner and outer pipes, and providing lubricant exhaust nozzles reaching the lubricant feed pipe from the outer periphery of the outer pipe. CONSTITUTION: An inner pipe 2 is arranged in an outer pipe 3, a lubricant feed pipe 4 is welded to the inner apex of the outer pipe 3, and a plurality of lubricant exhaust nozzles 5 reaching the lubricant feed pipe 4 from the outer periphery of the outer pipe 3 are provided at proper intervals. Mortar or concrete 6 is filled in the gap between the inner pipe 2 and the outer pipe 3 to form an advance steel pipe 1. At the time of execution, an lubricant is force-fed in the lubricant feed pipe 4 and is spouted from the exhaust nozzles 5, and execution is made while the frictional resistance between the outer pipe 3 and peripheral sediment is reduced.
