INSTALLATION MANAGEMENT METHOD FOR IMPACT INSTALLATION AND INSTALLATION MANAGEMENT SYSTEM FOR IMPACT INSTALLATION
To provide an installation management method for an impact installation allowing confirmation for a tip of a pile to reach a support layer in the ground and a better-perfect-impact-completion management to be carried out.SOLUTION: An installation management method for an impact installation comprises: a first image capturing step of capturing an image of a lattice pattern part provided on an outer surface of a pile; a first calculation step of calculating a penetration amount and a rebound amount per one impact on the pile, as well as the number of impacts required to reach a specific depth using a sampling moire method from a result of captured images captured in the first image capturing step; a management chart production step of producing a management chart plotting the penetration amount and the rebound amount calculated in the first calculation step for a penetration depth of the pile; an impact number chart producing step of producing an impact number chart on which every impact number to reach the specific depth calculated in the first calculation step is plotted for each of the penetration amounts of the pile; and a support layer reach determination step of determining whether or not the pile reaches the support layer of the pile based on the management chart and the impact number chart.SELECTED DRAWING: Figure 3
【課題】杭先端が地盤の支持層に到達したことを確実に確認でき、より完全な打ち止め管理を行うことができる打撃工法の施工管理方法を提供する。【解決手段】杭の外周面に設けられた格子柄部を撮影する、第一の撮影ステップと、第一の撮影ステップの撮影結果から、サンプリングモアレ法を用いて、杭の一打撃ごとの貫入量及びリバウンド量、所定深度あたりの打撃回数を算出する、第一の算出ステップと、第一の算出ステップで算出された貫入量及びリバウンド量を、杭の貫入深度に対してプロットした管理図を作成する、管理図作成ステップと、第一の算出ステップで算出された所定深度あたりの打撃回数を、杭の貫入深度に対してプロットした打撃回数図を作成する、打撃回数図作成ステップと、管理図と打撃回数図に基づいて、杭の支持層到達を判定する、支持層到達判定ステップと、を有する打撃工法の施工管理方法。【選択図】図３
