Abstract
A system for boring a hole in the ground including an excavating machine provided with a tubular body; an excavating mechanism supported by the body; a mechanism for shifting the excavated substances to the periphery of the body; and a driving mechanism for operating the excavating mechanism.
Claims12
A method for boring a hole in the ground comprising the steps of:
- advancing an excavating machine having a tubular body and excavating means disposed in the front portion of the body while excavating the ground by use of said excavating means;
- receiving excavated substances in a chamber behind said excavating means and formed in said body;
- subjecting a rotor disposed in the chamber to an eccentrical movement to radially propel the excavated substances;
- and
- thrusting substantially all of said excavated substances propelled by the rotor out of said body substantially uniformly around the periphery of said body through at least one excavated substance exit hole formed in said body laterally of said rotor and providing communication between the chamber and the outer periphery of said body.

An apparatus for boring a hole in the ground, said apparatus comprising:
- a tubular body;
- excavating means disposed at the front portion of said body to excavate said ground;
- a partition wall disposed inside said body to define together, with said body, a chamber for receiving substances excavated by said excavating means;
- thrusting means including a rotor disposed inside said chamber and movable eccentrically relative to said body, for thrusting out the excavated substances received in said chamber to the periphery of said body;
- a drive mechanism connected to said excavating means and to said thrusting means to drive said excavating means and said thrusting means;
- and
- at least one excavated substance exit hole formed in said body laterally of said rotor and providing communication between the chamber and the outer periphery of said body through which substantially all of said excavated substances are thrust out substantially uniformly around the periphery of said body by the eccentric movement of said rotor.

An apparatus for boring a hole in the ground, said apparatus comprising:
- a tubular body;
- excavating means disposed at the front portion of said body to excavate said ground;
- a partition wall disposed inside said body to define together, with said body, a chamber from receiving substances excavated by said excavating means;
- thrusting means including a rotor disposed inside said chamber and movable eccentrically relative to said body, for thrusting out the excavated substances received in said chamber to the periphery of said body;
- a drive mechanism connected to said excavating means and to said thrusting means to drive said excavating means and said thrusting means;
- and
- a plurality of excavated substance exit holes formed in said body laterally of said rotor and providing communication between the chamber and the outer periphery of said body through which substantially all of said excavated substances are thrust out substantially uniformly around the periphery of said body by the eccentric movement of said rotor.
