GROUND DRILLING DEVICE AND GROUND INVESTIGATION METHOD
To provide a ground drilling device and a ground investigation method that can insert a rod continuously in a rotational manner without requiring lifting and lowering a lifting unit, and that can improve work efficiency, the accuracy of ground data and safety.SOLUTION: The ground drilling device is composed of a rod, a turntable, a drive device and a delivery device. The tip of the rod includes a ground investigation device with an excavation function, and the rod is inserted into an investigated ground. The turntable in a plate shape includes a through hole that is formed at the center part of the turntable and that the rod can penetrate. The drive device rotates the turntable. The delivery device is provided on the turntable and the rod can be installed therein. The delivery device can deliver the rod continuously with a predetermined load or at a predetermined delivery speed, and can lift the rod continuously with predetermined lifting force or at a predetermined lifting speed.SELECTED DRAWING: Figure 1
【課題】 昇降ユニットの上昇・下降を必要とせず、連続的にロッドを回転貫入することができ、作業効率の向上と地盤データの精度及び安全性を向上させることができる地盤削孔装置及び地盤調査方法を提供すること。【解決手段】先端部に掘削機能を有した地盤調査装置を有し、調査地盤に挿入されるロッドと、板状で、その中央部に形成され、前記ロッドが貫通可能な貫通孔を有するターンテーブルと、該ターンテーブルを回転させる駆動装置と、前記ターンテーブルに設けられ、前記ロッドを装着可能な送り出し装置とで構成され、前記送り出し装置は、前記ロッドを所定の荷重又は送り出し速度でロッドを連続的に送り出すことができるとともに、所定の引き上げ力又は引き上げ速度でロッドを連続的に引き上げることができることを特徴とする。【選択図】 図１
