摘要： PURPOSE: To simplify a structure and facilitate the direction correction by constituting a slide edge attached to an auger shaft by a pin connection in such a state as freely entering/retreating from a guide cylinder by the rotation of the auger shaft. CONSTITUTION: An enlarged edge mechanism 3 is so constituted that a slide edge 32 slidably held by a guide cylinder 34 provided in a cylinder part 21 and projecting its tip further outward than an excavation locus of a cutter held 2 in projected to the outside is attached to a bracket 31 projected to a rod part 12 via a pin 33. When the excavation diameter is enlarged, the cutter head 2 is pushed against a natural ground to restrict the rotation, an auger shaft 1 is inversely rotated to thrust the slide edge 32 and project it outside from the guide cylinder 34 so that an enlarged hole with a diameter larger than the excavation diameter of the cutter head 2 is excavated and this excavation can facilitate the correction of the direction.

摘要： PURPOSE: To easily correct an advancing direction by projectably housing an excavator inside an outer pipe provided with an eccentrically inclined inner peripheral surface. CONSTITUTION: The outer pipe 1 is a hollow cylindrical body and is formed by making the center of an internal hole eccentric to the axial center of the cylindrical body at a fixed angle. As a result, for the thickness of the tip part of the outer pipe 1, the thick part 11 of the maximum thickness and the thin part 12 of the minimum thickness are respectively formed at symmetrical positions. The outer pipe 1 houses an auger device 2 as the excavator capable of advance digging projectably.

摘要： PURPOSE:To obtain a system calculating accurate displacement quantity within a short time without the direct collimation of a surveyor, by forming the data obtained by binarizing the image signal, which is obtained by the collimation photographing of a target by a CCD camera, and the reflection of the CCD camera into images to display the same. CONSTITUTION:A transit 2 collimates the rotary target 1 mounted on the article A to be measured of an excavator at a definite cycle and the image of said target 1 is formed into a signal by a CCD camera 3 to be transmitted to a displacement detector 4 where said signal is binarized to be displayed on a monitor 5. That is, the coordinates signal of the present position of the target 1 transmitted to the monitor 5 and a reference point for surveying set are respectively formed into figures or drawings to be displayed. When the distance from the target 1 to the transit 2 is inputted to a computer 6, the displacement quantities from the reference point in both X- and Y-directions are calculated in the computer 6. These displacement quantities are respectively displayed as numerical values in both directions and a drawing is displayed in the form of coordinates.
