UNDERGROUND CONTINUOUS WALL EXCAVATOR AND UNDERGROUND CONTINUOUS WALL EXCAVATION METHOD
PROBLEM TO BE SOLVED: To provide an underground continuous wall excavator and an underground continuous wall excavation method, which improve work efficiency even at a great deep region by reducing the excavation cycle time and improving the excavation pitch while maintaining the excavation accuracy.SOLUTION: An underground continuous wall excavator excavates an excavation groove by opening and closing a bucket 10 comprising a pair of right and left shells 11, 12 by a hydraulic cylinder. As the hydraulic cylinder, two hydraulic cylinders comprising a first hydraulic cylinder 20 and a second hydraulic cylinder 30 are disposed in series in a vertical direction so that respective rod side ends 21, 31 face each other. The bucket 10 is closed by elongating the first hydraulic cylinder 20 and contracting the second hydraulic cylinder 30, while the bucket 10 is opened by contracting the first hydraulic cylinder 20 and elongating the second hydraulic cylinder 30.SELECTED DRAWING: Figure 1
【課題】掘削精度を維持した上で、掘削のサイクルタイムを短縮させ、併せて掘削ピッチの改善を図ることによって大深度域においても作業効率を向上させる地中連続壁掘削機及び地中連続壁掘削工法を提供する。【解決手段】左右一対のシェル１１，１２からなるバケット１０を油圧シリンダによって開閉動作させて掘削溝を掘削する地中連続壁掘削機において、前記油圧シリンダとして、第１油圧シリンダ２０と第２油圧シリンダ３０からなる２基の油圧シリンダを、相互にロッド側端部２１，３１を対面させて上下方向に直列配置し、第１油圧シリンダ２０が伸長するとともに、第２油圧シリンダ３０が縮小することによってバケット１０を閉じ、第１油圧シリンダ２０が縮小するとともに、第２油圧シリンダ３０が伸長することによってバケット１０を開く地中連続壁掘削機。【選択図】図１
