３２５号公報参照）。Conventionally, as one of the underground pipe propulsion construction methods, a leading pipe with a blade at the front end is connected to the front end of the buried pipe propelled by gloss, and a pipe is provided inside the leading pipe that slopes so as to spread forward and upward. A pair of left and right side guide plates are used to guide the earth and sand that enters the guide pipe to the rear of the weir plate at the rear of the lower end of the side guide plates. Water is supplied from the water pipe onto the upper guide plate that is inclined to the upper guide plate, and this water flows down in a film form from the rear edge of the upper guide plate to be supplied to the earth and sand behind the weir plate. A method is known in which water and sand are mixed with a rotating stirring blade, sucked in with a vacuum suction pipe, and discharged to the outside.
