INSTALLATION MANAGEMENT DEVICE, INSTALLATION MANAGEMENT METHOD, AND INSTALLATION MANAGEMENT PROGRAM
PROBLEM TO BE SOLVED: To provide a technology capable of properly confirming that the tip of a hole reaches a support layer when forming a hole for inserting a pile such as a steel pipe pile by excavating the ground by striking a drilling tool such as a drilling bit.SOLUTION: The installation management device includes an information acquiring unit and a determination unit. The information acquiring unit acquires excavation depth information indicating the excavation depth of the drilling tool and hit count information indicating the number of hits per predetermined penetration amount of the drilling tool corresponding to the excavation depth about an excavator which excavates the ground by hitting the drilling tool. The determining unit determines whether or not the drilling tool at the excavation depth indicated by the excavation depth information has reached the support layer based on the number of hits per predetermined penetration amount indicated by the hit number information.SELECTED DRAWING: Figure 7
【課題】削孔ビット等の削孔具に打撃を加えて地盤を掘削して、鋼管杭等の杭を挿入する削孔を形成する際に、削孔先端が支持層に到達したことを適切に確認可能な技術を提供する。【解決手段】本発明の一側面に係る打設施工管理装置は、削孔具に打撃を加えて地盤を掘削する掘削機について、前記削孔具の掘削深度を示す掘削深度情報と、前記掘削深度に対応した、前記削孔具の所定貫入量当たりの打撃回数を示す打撃回数情報と、を取得する情報取得部と、前記打撃回数情報の示す所定貫入量当たりの打撃回数に基づいて、前記掘削深度情報の示す掘削深度にある前記削孔具が支持層に到達したか否かを判定する判定部と、を備える。【選択図】図７
