By moving all or part of the burial digging device from above the pipe burial center line, up and down,
It is provided so that it can move to the left and right position or the diagonally up and down position, and the space of the movement mark can be used for connecting various connecting pipes and other work, so that the hand space in the start pit is smaller than before. The present invention relates to a pipe burying method and a pipe burying device, which are characterized in that they can be made extremely small.

II) ... Conventional technology and its problems (1) ... Currently, pipes (fume pipes, steel pipes, PVC pipes) for gas, water and sewage, telegraph and telephone cables, etc., underground, such as roads, railways, building structures, and other obstacles. Etc.) is buried,
A starting pit (vertical pit) and a reaching pit are opened in a part of the road, etc., and a rotation mechanism (consisting of a motor, a box, etc.) is provided inside the starting pit.
And a propulsion mechanism (comprising a hydraulic cylinder device) are installed in the pipe burial excavation device. For example, as shown in (i), FIG. The screw conveyor 4a fitted with the pressure contact pilot pipe 4b (hereinafter referred to as the connection pipe 4)
After being driven by the propulsion mechanism while being rotated by the rotating mechanism of the pipe burial cutting device 1, the connecting pipes 4 are connected one after another and rotationally propelled to excavate the pilot pit to the reaching pit, and then the last pit. The excavating head 3 is attached to the connecting pipe 4, and the excavating head is rotated and propelled to push and embed the pipes 2 (illustrated side, fume pipe) of a set length one after another, (ii) or the applicant No. 62-314491 filed by the above-mentioned Japanese Patent Application No. 62-314491, the frontmost superimposing pipe 5 (set length, eg,
After rotating and propelling 1 m of each direction control pipe, drain pipe, sheath pipe, buried pipe, etc.), connect the polymerization pipes 5 one after another to penetrate to the reaching pit, and then leave the buried pipe. Other polymerization tubes are successively retracted and removed to embed tubes (illustrated example, PVC pipes) and the like.

(2) However, not limited to the above example, when connecting a connecting pipe or the like on the pipe burying center line l in the starting mine and rotatably propelling the pipe by a pipe burial digging device, the starting is started.
