BORING SYSTEM AND BORING METHOD
To bore a pipe lining material that blocks a branch pipe opening by positioning a drilling blade at the branch pipe opening from the main pipe side even in the case that the branch pipe opening is blocked by the pipe lining material which hardly transmits visible light or never transmits visible light.SOLUTION: A boring system comprises: a first boring device 14 provided with a drilling blade 28 for boring a pipe lining material 13 from a main pipe side; and a second boring device 30 provided with a drilling blade 34 for forming an opening for transmitting illumination light from a light source 37 through the pipe lining material blocking a branch pipe opening 12a. The opening formed by the second boring device is photographed by cameras 27 on the main pipe side, and the drilling blade 28 is positioned on the basis of photographed images of the opening.SELECTED DRAWING: Figure 1
【課題】枝管開口部が可視光を透過しにくいあるいは可視光を透過しない管ライニング材で塞がれている場合でも、本管側から穿孔刃を枝管開口部に位置決めして該枝管開口部を閉塞している管ライニング材を穿孔する。【解決手段】管ライニング材１３を本管側から穿孔する穿孔刃２８を備える第１の穿孔装置１４と、枝管開口部１２ａを閉塞している管ライニング材に光源３７からの照明光を透過させる開口部を形成する穿孔刃３４を備えた第２の穿孔装置３０が設けられる。第２の穿孔装置により形成された開口部が本管側のカメラ２７により撮影され、その開口部像に基づいて穿孔刃２８の位置決めが行われる。【選択図】図１
