The excavating means 110 is configured such that one end of the excavating means 110 is in surface contact with the ground so as to excavate the ground. That is, the excavating means 110 is composed of a rotary shaft 111 and a screw member 117 and a drilling head 113 which are elongated from the propelling unit 200 toward the ground excavation direction.

The rotation shaft 111 is connected to one end (rear end) of the propelling unit 200 and is rotatably installed by applying a rotational force from the propelling unit 200.

The rotary shaft 111 is elongated toward the advancing direction and a plurality of rotary shafts 111 having a predetermined length propable from the propulsion unit 200 are continuously connected to the rear to connect the propulsion base 10, To the reaching base (20).

2, the drilling head 113 is coupled to the front end of the rotary shaft 111 and rotates, and the ground is excavated from the front of the pipe pipe 120.

As shown in FIGS. 3 and 4, the excavation head 113 includes a excavation member 114 that performs a function of excavating in contact with the ground, And an opening / closing member 115 which performs a function of setting the opening / closing member.

The excavation member 114 is formed in a circular plate shape corresponding to the diameter of the pipe 120 and has a structure in which a plurality of crushing blades 114a and an inflow hole 114b are formed.
