CONSTRUCTION SUPPORT SYSTEM AND CONSTRUCTION SUPPORT METHOD OF FOUNDATION PILE
To provide a construction support system of a foundation pile that can keep an alignment error of a plurality of piles within an allowable range while keeping a deviation between an actual pile core and a designed pile core of each pile within an allowable range, when driving the piles simultaneously.SOLUTION: A construction support system of a foundation pile comprises: a RiDAR that measures distances by scanning measurement light in a direction intersecting a pile core of each pile held by each of a plurality of pile drivers and driven into the ground; an actual pile core data calculation section that calculates pile core data for each pile based on three-dimensional point cloud data of each pile obtained by the RiDAR; a correction information calculation section that calculates correction information for each pile based on actual pile core data and design pile core data of each pile calculated by the actual pile core data calculation section so that the actual pile core data of each pile converges within an allowable range of each design pile core data and the alignment error in plan view of each pile converges within a specified allowable range; and a plurality of terminal devices that individually displays the correction information for each pile calculated by the correction information calculation section.SELECTED DRAWING: Figure 2
【課題】複数本の杭を同時に打設する場合に、各杭の実杭芯と設計杭芯との偏差を許容範囲に抑えながら、複数本の杭の配列誤差を許容範囲に抑えることが可能な基礎杭の施工支援システムを提供する。【解決手段】基礎杭の施工支援システムは、複数の杭打機の其々に保持され地中に打設される各杭を各杭の杭芯と交差する方向に測定光を走査して距離を計測するＲｉＤＡＲと、ＲｉＤＡＲで得られる各杭の３次元点群データに基づいて各杭の杭芯データを求める実杭芯データ算出部と、実杭芯データ算出部で求めた各杭の実杭芯データと設計杭芯データとに基づいて、各杭の実杭芯データが各設計杭芯データの許容範囲に収束するとともに、各杭の平面視の配列誤差が所定の許容範囲に収束するように、各杭に対する補正情報を算出する補正情報算出部と、補正情報算出部で算出した各杭に対する補正情報を個別に表示する複数の端末機器と、を備えている。【選択図】図２
