摘要： PROBLEM TO BE SOLVED: To provide a boring shaft inclination control method whereby the shift of the position of a borehole can be monitored at each moment without stopping the rotation of a boring shaft and a boring shaft position correcting method whereby the position of the borehole is corrected. SOLUTION: A plurality of boring shafts 1 are connected together by a connector 3 at their respective parts slightly above a bit part, and a horizontal boring shaft 4 projecting from the connector is provided on an orthogonal line passing the center point of a straight line connecting the axes of the boring shafts 1 together. A clinometer 7 for measuring the inclination of the connector 3 caused by the inclination of each boring shaft 1 is fixed in position either inside the connector 3 or on the upper surface of the connector 3 between the axes of the boring shafts 1, so that the inclination of the end of each boring shaft 1 can be controlled at each moment on the ground according to information about the X-Y direction position of the connector 3, which is provided from the clinometer 7, and information about boring depth near a bored part. A method for correcting the position of each boring shaft includes pressing the earth wall of the borehole by moving the horizontal boring shaft 4 back and forth, thereby changing the inclination angle of each boring shaft 1.

摘要： PROBLEM TO BE SOLVED: To construct a soil cement wall in which penetration of water is hard to occur and which is strong against external forces. SOLUTION: In the excavator, a plurality of excavation shafts 1 are parallelly disposed and the outer peripheries of bits parts 2 of the adjacent shafts 1 overlap each other in the plan view when the bit parts each provided on the shafts 1 are vertically offset. There are provided a connection body 3 which connects the upper parts of the bit parts 2 to rotates them and forms a contour, through which all bits are included in the plan view, horizontal rotation axes 4 each horizontally passing through the middle point between the adjacent shafts 1 so as to protrude out of the body 3, excavation vanes 5 provided around the horizontal rotation axis 4, and a flat receiving plate 6 vertically provided at the end of each of the axes 4. The outer surface of the plate 6 is nearly aligned with a common tangent line to a circle formed by the rotating bit part 2, in the plan view.

摘要： PROBLEM TO BE SOLVED: To provide a digging machine for construction, by which positional shifting of a drilled hole can be monitored in real time without releasing a digging shaft from a rotary driving device. SOLUTION: A digging machine is so constructed that a little upper parts of bit parts 2 in plural digging shafts 1 are connected to each other by a connector 3 and a horizontal digging shaft 4 projected from the connector 3 is provided on an orthogonal passing through the center point of a straight line connecting between the shaft centers of the digging shafts 1, 1. Further, the machine comprises plural connectors 5 for connecting the digging shaft 1 parts above the connector 3, an inclinometer 7 which is disposed between the shaft centers of the digging shafts 1, 1 on the upper surface of the connector 3, a bar-like bar member 6 which is positioned in a space part digged by the horizontal digging shaft 4 in a plan view and provided in such a manner as to be stretched between the connectors 5, and a hollow connecting member 8 for connecting the inside of the bar-like member 6 and the inside of the cover 71 to each other in water-tight state, and a transmission cable 70 of the inclinometer 7 is passed through the interiors of the connecting member 8 and the bar-like member 6 to be guided to the ground.

摘要： PURPOSE:To provide the work display monitor of a pile driver useful for the selection and operation confirmation of the control lever or switches of a winch or the like. CONSTITUTION:Pressure switches 17a, 17b and the like laid in the pilot pipe lines 13a and 13b, for example, of a control valve 14 for selecting and controlling the operation of a winch are used to detect whether or not a lower travel body, an upper turning body and a plurality of winches are operating. Also, a display member 20 for showing the result of the detection is provided in an operator cab, thereby informing an operator of whether any of the lower travel body, the turning body and a plurality of winches is currently operating for a specific control lever or a switch.
