徴とする小口径シールドの測量装置。 It is equipped with a shield body for excavating a face, an earth removal auger shaft installed inside the shield body along its axis, and a propulsion device for propelling a buried pipe connected to the shield body and the rear end of the shield body. On the other hand, a transit is installed at a reference position for surveying on the propulsion device side, and a target is installed opposite to the transit inside the tip of the shield body or inside the earth removal auger shaft and has a built-in light emitting diode. A small-diameter shield configured to include a surveying device consisting of a surveying device configured to monitor and survey the displacement of the light spot of the light emitting diode using the transit to make the shield main body dig along a desired straight line.
A small-diameter shield surveying device characterized by having a transmission hole that transmits light traveling straight from a light emitting diode toward a transit, and a shielding plate that blocks other scattered light.
