摘要： PROBLEM TO BE SOLVED: To obtain excavating machinery and an excavation method, which enhance the circularity of an intermediate diameter-enlarged portion by reducing the deviation of the central axis of the intermediate diameter-enlarged portion and that of a vertical hole from each other, and which enable excavated sediment to be recovered in a short period of time.
SOLUTION: An excavator 10 with a diameter-enlarged excavating bucket 22 comprises a stabilizer portion 36 which is brought into contact with a hole wall of a pile hole 20 so as to guide the center of a fixed post 24 to a central position of the pile hole 20, and a sediment recovery bucket 96 which is brought into contact with the hole wall of the pile hole 20 so as to guide the center of the fixed post 24 to the central position of the pile hole 20, and which recovers the excavated sediment of the intermediate diameter-enlarged portion 56. At the start of the excavation of the intermediate diameter-enlarged portion 56, the stabilizer portion 36 and the sediment recovery bucket 96 are brought into contact with the hole wall of the pile hole 20, so as to keep the center of the fixed post 24 in the central position of the pile hole 20. Thus, the circularity of the intermediate diameter-enlarged portion 56 can be enhanced. Additionally, since the excavated sediment of the intermediate diameter-enlarged portion 56 is recovered by means of the sediment recovery bucket 96, suspended sediment in the pile hole 20 is reduced, and the excavated sediment can be recovered in a short period of time.

摘要： PROBLEM TO BE SOLVED: To provide a bucket for diameter-widening excavation, which can form an intermediate diameter-widened section having a lower inclined surface at an intermediate location of a pile hole, and has general versatility imparted thereto.
SOLUTION: According to the structure of the bucket, a widening blade section 30 is rotatably suspended from an excavator main body 16, and by rotatively expanding/contracting the widening blade section 30, a hole wall in a shaft 20 is excavated to form the intermediate diameter-widened section 56 at the intermediate location of the shaft 20. The widening blade section 30 has a detachable arm section 34 attached to a lower edge thereof, which arm section 34 is rotated and expanded/contracted together with the widening blade section 30, to thereby form the inclined surface 56C converging to the center of the shaft 20, at a lower portion of the intermediate diameter-widened section 56. Therefore by attaching the arm section 34 conforming to the inclined surface at the intermediate diameter-widened section to be excavated, to the lower edge of the widening blade section 30, the bucket is applicable to excavation of the different inclined surface at the lower portion of the intermediate diameter-widened section.

摘要： PROBLEM TO BE SOLVED: To provide a bucket for diameter-widening excavation, which contributes to a reduced machine height.
SOLUTION: According to the structure of the bucket for diameter-widening excavation, the rotational center of a hinge 94 in a bottom lid 96 is located at a location inner than a peripheral edge of the bottom lid 96, and therefore a distance from the location of the hinge 94 in the opened bottom lid 96 to the peripheral edge of the bottom lid 96 is shorter than a distance of a maximum external diameter of the bottom lid 96. Thus compared with a conventional bucket in which the hinge 94 is located at an edge of the bottom lid 96, a distance from the peripheral edge of the diameter-widening bucket 10 to the ground surface when the diameter-widening bucket 10 is lifted up to the ground surface can be set to a shorter value, which contributes to the reduced machine height of an excavator 27.

摘要翻译：要解决的问题：提供一种用于直径加宽挖掘的铲斗，其有助于降低机器高度。解决方案：根据用于直径加宽挖掘的铲斗的结构，底盖96中的铰链94的旋转中心位于比底盖96的周边边缘更靠内的位置，因此距离从打开的底盖96中的铰链94的位置到底盖96的周边边缘的距离短于底盖96的最大外径的距离。因此，与常规的铲斗相比，铰链94 位于底盖96的边缘处，当直径加宽桶10被提升到地面时，从直径加宽桶10的周缘到地面的距离可以设定为较短的值，其中有助于减少挖掘机27的机器高度。版权所有（C）2008，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To obtain a bucket for diameter-enlarging excavation by which a diameter enlarging ratio is increased and the height of a machine is reduced.
SOLUTION: A hydraulic cylinder 72 is swingably mounted on a lifting frame 40. The rotation amount of a transmission member 60 and an opening/closing link 68 rotated by the telescopic motion of a piston rod 80 is amplified by a lower arm 50 and the opening/closing link 68, and is converted to a movement amount in a vertical direction of the lifting frame 40 and in a diameter-enlarging direction of an enlarging blade 16. Therefore, the lifting frame 40 and the enlarging blade 16 can be moved more largely than the telescopic movement of the piston rod 80. Consequently, the diameter enlarging ratio can be increased and the height of the machine for lifting a front end part of a diameter-enlarging bucket 10 to the ground surface can be reduced.

The earth retaining wall 10 is formed at a height H1 between a ground surface 42 and an excavation bottom surface 34, and a sandy soil layer 12 requiring water shielding is present in a part of the excavation surface 16. The earth retaining wall 10 is provided with an H-steel 20. The H-steel 20 is built in an excavation hole 18 and the foot is protected. The excavation hole 18 is excavated to a depth H2 reaching a sandy soil layer 13 by a diameter D1, and an excavation diameter is enlarged to a diameter D2 at a part where the excavation hole 18 passes through the sandy soil layer 12. Inside the excavation hole 18, a soil cement column 26 for which cement milk and excavated soil are mixed and agitated is constructed. At a columnar part whose diameter is enlarged to the diameter D2, adjacent outer peripheral parts are wrapped and a wall-like soil cement column water shielding part 22 is constructed.
