| description | PROBLEM TO BE SOLVED: To provide a method of cutting only a hard sediment accumulated within a structure and recovering the same without accompanying with exchanging the cutting-head and without damaging the structure.SOLUTION: A sediment recovery method repeats a cutting step of cutting a part of a sediment S accumulated in a structure C by using an AWJ cutting device 1, and a recovery step of recovering a recovery piece P cut out from the sediment S by the cutting step. The cutting step performs a first cutting step of injecting a jet flow from a first direction inclined to a virtual vertical lines Z-Z erected on the sediment and putting a first cut N1 on a part of the sediment S; and a second cutting step of injecting a jet flow from a second direction opposite to the first direction through the virtual vertical lines Z-Z and putting a second cut N2 reaching a top end of the first cut NI at the top end.SELECTED DRAWING: Figure 3
【課題】切断ヘッドの交換を伴わずかつ構造物を損傷することなく、構造物内に堆積した硬質の堆積物のみを切断して回収する工法を提供する。【解決手段】ＡＷＪ切断装置１を用いて構造物Ｃ中に堆積した堆積物Ｓの一部を切断する切断工程と、切断工程により堆積物Ｓから切り出された回収片Ｐを構造物Ｃ外に回収する回収工程とを繰り返す。切断工程は、堆積物に立てられた仮想の垂直線Ｚ−Ｚに対して傾斜する第１の方向からジェット噴流を噴射し、堆積物Ｓの一部に第１の切れ込みＮ１を入れる第１の切断工程と、仮想の垂直線Ｚ−Ｚを介して第１の方向とは反対側の第２の方向からジェット噴流を噴射し、先端が第１の切れ込みＮ１の先端に達する第２の切れ込みＮ２を入れる第２の切断工程とを行う。【選択図】図３ |
