Title:
流体管の導入装置及びそれを用いた埋設方法
Document Type and Number:
Japanese Patent JP6869816
Kind Code:
B2
Abstract:
To provide a fluid pipe introduction device capable of suppressing influence of sediment on a fluid pipe by accumulating the sediment substantially evenly in a horizontal direction in an axial view of the fluid pipe, the sediment occurring in excavation, and a burial method using the fluid pipe introduction device.SOLUTION: A fluid pipe introduction device comprises an excavation function unit 3 configured to excavate sediment, rotation drive devices 4, 4' configured to rotate the excavation function unit 3, and an advance/retreatment drive device 6 configured to advance/retreat the excavation function unit 3 and the rotation drive devices 4, 4' in substantially parallel with the underground. In the fluid pipe introduction device, excavation units 30, 30' are installed at least below an outer peripheral surface of a fluid pipe 2 so as to make a pair horizontally in a view from a pipe axis direction, where the excavation units projecting radially from an axial core constituting the excavation function unit 3; and the rotation devices 4, 4' rotate the excavation units in mutually opposite directions around the axial cores of the excavation units 30, 30'.SELECTED DRAWING: Figure 1
