Abstract: PURPOSE: To perform highly accurate horizontal excavation in a narrow area of an excavating space by making an excavating tool enter for excavation from a pit mouth of the ground surface, and controlling an azimuth and an inclination of a well while always confirming a position of the excavating tool by using an electromagnetic wave. CONSTITUTION: Devices required for excavation such as an excavating muddy water tank, a muddy water pump, a mixing device of a mud material and water, a device for generating thrust and torque in an excavating pipe and a hydraulic motive power device are mounted on a vehicle to be arranged in the vicinity of a pit mouth. Then, an excavating tool is made to enter for excavation from an underground entrance 91 by using these devices to obtain pit core measuring information of a well to always detect a position of the excavating tool on the tip of the well by sending an electromagnetic wave from aboveground by an excavating tool position detecting device. While controlling an azimuth and an inclination of the well from aboveground on the basis of a position of the detected excavating tool, a boring advance is continued toward an arrival vertical shaft 97.
