GUIDE APPARATUS FOR ADAPTIVELY DRILLING IN VARIOUS FIGURES AND CONDITIONS OF GROUND

摘要

PURPOSE: A topographical condition adaptive ground boring guide device is provided to automatically maintain the perpendicularity of boring using an automatic horizontality guide device. CONSTITUTION: A topographical condition adaptive ground boring guide device(100) comprises a guide structure(2), multiple support legs(4), a tubular casing(12), a level detection sensor, horizontal rotary wheels, and a controller. A vertical guide hole(10) is formed in the center of the guide structure. The support legs are installed in the guide structure and are vertically extendable. The tubular casing is inserted into the vertical guide hole. The level detection sensor is buried in the guide structure and senses the horizontal state of the guide structure. The horizontal rotary wheels are buried in the inner wall of the vertical guide hole and have guide rollers. The controller controls the device.
