METHOD FOR REMOVING CIRCULAR CHANNEL
PROBLEM TO BE SOLVED: To provide a method for removing a circular channel that can remove the entire section of a failed circular channel portion without damaging the other portion of the circular channel.SOLUTION: The front and rear positions of a prescribed section regarding a failed existing circular channel 1 is vertically cut by a blade of a rotary blade cutting machine so as to form a first concrete unit 14 to be removed, and the first concrete unit 14 to be removed is hoisted and removed. After the removal, the rear position of a prescribed section of a subsequent circular channel is vertically cut and is divided right and left to be half-split circular channels so that second and third concrete units to be removed are formed and are hoisted and removed. The method for removing the second and third concrete units to be removed is repeated over the longer direction so that the existing circular channel with a prescribed length is removed.SELECTED DRAWING: Figure 6
【課題】不具合の生じた円形水路部分の区画全体を、残存させる円形水路に損傷を与えることなく撤去することを可能とする円形水路の撤去工法を提供する。【解決手段】不具合の生じた既設の円形水路１を回転刃切断機によるブレードにより所定区間の前後位置を垂直切断して第１の撤去コンクリートユニット１４を形成し、第１の撤去コンクリートユニット１４を吊り上げ撤去し、その撤去後、それに続く円形水路の所定区間後方位置を垂直切断し、且つ、左右に分割して半割円形水路とした第２、第３の撤去コンクリートユニットを形成して吊り上げ撤去し、この第２、第３の撤去コンクリートユニットの撤去方法を長手方向にわたって繰り返すことにより所定長の既設円形水路を撤去することから構成される。【選択図】図６
