前記掘削治具に取り付けられて、前記拡大翼の拡径・縮径状態の経時的変化を計測し、その計測結果を記憶する拡大翼変化計測記憶手段と、
地上に設置されて、前記拡大翼が位置する深度の経時的変化を計測し、その計測結果を記憶する拡大翼深度計測記憶手段と、
前記掘削治具が地上に引き上げられた際に、前記拡大翼変化計測記憶手段に記憶されている計測結果を取り出す拡大翼変化計測結果取得手段と、
前記拡大翼深度計測記憶手段によって計測された拡大翼の深度の経時的変化と、前記拡大翼変化計測結果取得手段によって取り出された拡大翼の拡径・縮径状態の経時的変化とを統合し、それによって得られる深度と掘削径の関係に基づいて、根固め球根部の形状を検知する根固め球根部形状検知手段と
を備えていることを特徴とする基礎杭施工における根固め球根部の形状確認システム。 Using a drilling jig for foundation pile construction, which is supported by the tip of the excavation rod so that the diameter of the excavation rod can be expanded and has an expansion blade attached with a blade for expansion excavation, the diameter of the expansion blade is expanded for excavation. This is a system for confirming the shape of the rooted bulb in foundation pile construction in order to confirm the shape of the rooted bulb that has been built in the foundation pile construction in which the rooted bulb is built in the middle or lower part of the drilling hole. And
Attached to the excavation jig, measures the change over time of the diameter expansion / reduction state of the expansion blade, and expands blade change measurement storage means for storing the measurement result;
An enlarged wing depth measurement storage unit that is installed on the ground, measures the change over time of the depth at which the enlarged wing is located, and stores the measurement result;
When the excavation jig is pulled up to the ground, the enlarged blade change measurement result acquisition means for extracting the measurement result stored in the enlarged blade change measurement storage means;
The time-dependent change in the depth of the expansion blade measured by the expansion blade depth measurement storage unit and the time-dependent change in the diameter expansion / reduction state of the expansion blade extracted by the expansion blade change measurement result acquisition unit are integrated. Rooting bulb shape detecting means for detecting the shape of the root compaction bulb based on the relationship between the depth obtained and the diameter of the excavation and the shape of the root compaction bulb. Shape confirmation system.
