Abstract

PURPOSE: To prevent noises and vibrations as well as the breakage of a traversing pipe and the like by pushing a corrugated plate into a duct in the state that a guide rail is engaged with the guiding member of a beam in the sheathing device for excavating the duct wherein a main sewer or the like is buried.
CONSTITUTION: The duct being excavated, a frame member formed by connecting the beam 1 with a connecting member 2 is arranged in the duct. Then, the corrugated plate 3 is inserted into the duct under the condition that the guide rail 9 is engaged with each guiding member 4 of the beam 1, the lower end of the plate is pushed into earth, and the corrugated plate 3 is made to sink by its own weight along guide members 4 excavating and discharging the earth between the opposed beams 1. When the duct is made down to a prescribed depth, the main sewer or the like is put down in the duct, the corrugated plate 3 is pulled out, the beams 1 are pulled up and then burying is conducted.
