METHOD OF PIPING DRAWING-IN CONSTRUCTION

摘要

PURPOSE:To reduce the quantity of a drive ditch excavated extremely while simplifying a landslide protection wall, to charge and connect pipes in a small number of connecting sections, and to simplify the excavation operation of the drive ditch and the charging operation of the pipes while largely shortening the connection time of the pipes. CONSTITUTION:Fluidized soil 7 using excavated soil is placed on the floor face of a drive ditch 2. A smooth surface is formed in the floor face of the drive ditch by hardening the fluidized soil 7. The surface of the fluidized soil 7 of the drive ditch 2 is slid while successively welding pipes 1 charged at the predetermined fixed place 3 of the drive ditch, and drawn into the drive ditch 2.
