摘要： PURPOSE: To improve workability by sliding a pair of drums in the axial direction, changing excavation width while placing a projecting piece at the discontinuous section of a sliding section and excavating a section corresponding to the discontinuous section by a bit mounted on the projecting piece. CONSTITUTION: An excavator 10 bringing a pair of drum components 18a near by an expansion-contraction mechanism 24 is lowered, cutter drums 18 are rotated, and an underground hole A in narrow width is excavated up to specified depth. The other drum component 18a is separated from one drum component 18a by the mechanism 24, and the width of the cutters 18 is increased while the revolution of the cutters 18 is continued and the width of the hole A is broadened. The excavator 10 is brought down, and the hole A in board width is formed continuously. Projecting pieces 18c are drawn out from discontinuous sections 18b formed to the drum components by expansion and contraction operation at that time. Since bits 21 for excavation are installed onto the surfaces of the projecting pieces 18c, the ground corresponding to the discontinuous sections 18b is also excavated. Accordingly, operation can be simplified, and excavation efficiency can be enhanced.

摘要： PURPOSE: To improve workability by detecting the place of excavation, the quantity of an adjusting guide expanded and contracted and the inclination of an excavator body during excavation operation and adjusting each quantity of the adjusting guide and a cutter drum expanded and contracted on the basis of the results of detection. CONSTITUTION: Cutter drums 13, in which pairs of drum components 13a are separated and elongated, are rotated, and an excavator body 11 is lowered and the ground is excavated up to specified depth. Adjusting guides 12 mounted on the side face of the main body 11 are extended, and abutted against the inwall of an excavated pit. Information detected by a position sensing means 14, displacement detecting means 15 and an inclination detecting means 16 and the quantities of expansion arms 18 stretched are transmitted to a control tit 17. A place is decided, the quantities of the guides 12 elongated are adjusted, the place is corrected, and excavation is continued while the position and posture of the main body 11 are controlled similarly. The cutters 13 are shrunk at the place of a sectional change and the ground is excavated, and the position and posture of the main body II are controlled similarly. Accordingly, the ground can be excavated efficiently with high accuracy, and operation can be simplified.

摘要： PURPOSE:To accurately measure the position of excavator in horizontal plane regardless of the degree of depth and the behavior of the excavator. CONSTITUTION:A measuring wire 36 supplied from the ground with a constant tension is passed over a pulley 40 at the top end of an excavator 39 and guided out on the ground 3, its end is movably supported in a horizontal plane and in the state the excavator 39 is positioned on the planned excavation line, the origin of a plane coordinates is defined as the end of a measuring wire 36 perpendicular to the excavator 39. On the other hand, following the movement of the excavator 39, the end of the measuring wire 36 is moved keeping the wire perpendicular to the excavator 39 and the position of the end is measured and thus the position of the excavator 39 is reproduced on the ground.

摘要： PURPOSE:To improve workability by a method wherein a slippage in position of an excavator at each of depths is calculated with a similar ratio of triangle, based on a fixed value such as a boom length, starting value of measurement at the starting of excavation and measurement values during the excavation, and the calculated results are graphically displayed. CONSTITUTION:Fixed values such as the length of a boom 2, the height of an excavator 4, encoding pulse numbers of a displacement measurement device 15 that measures the displacement at the starting of excavation and starting value for measuring boom hoisting angles in a boom hoisting angle measurement device 28 are stored in a computer. Then, the measurement values obtained during excavation by the devices 15 and 28 and a depth measurement device 27 are inputted into the computer. Then, the computer automatically calculates with similar ratio of a triangle the slippage in the center of the upper bed of the excavator 4 at each of depths against the projected line of excavation, based on each of the measured values, the fixed values and the starting values, and the calculated result is displayed. Values of measurement by an angle meter 29 are also inputted, and the posture of the excavator 4 at each of the depths is displayed graphically. Thereby the measurement can be executed correctly and real time posture of the excavator can be judged by an operator.

摘要： PURPOSE:To unify the judgment reference of an operator at the time of the excavation work and improve excavation accuracy by visually confirming the aging change of the attitude of an excavator with a display device such as a color monitor. CONSTITUTION:The aging change (locus) of the attitude in the longitudinal direction of an excavator at each depth from a certain point to the present is displayed in a longitudinal attitude locus display area 3a. The tilt angle in the longitudinal direction of the excavator and the deviation quantity in the longitudinal direction from the excavation planned line 6 at the tip of the excavator at each depth are drawn by a plurality of arrow frames, for example. The tilt angle or the like of the excavator is drawn by a plurality of arrow frames in a right/left attitude locus display area 3b. The change of the attitude is drawn in a color different from the background color of the arrow frame indicating the present attitude for conspicuousness. An operator makes an excavation while observing the drawn attitude of the excavator.
