摘要： PURPOSE:To improve excavation efficiency by forming opening parts at an interval of a given angle in the lower part of a vertical casing incorporating a small lateral hole excavating device for a cable pipe and mounting the excavating device such that the direction of the device is variable in a given angle arc at a time. CONSTITUTION:Two or more opening parts 9A and 9B are formed at an interval of 90 deg. in the lower part of a casing 1b inserted in a vertical hole excavated in a road. A lateral hole excavating tool 8 and a rotation drive device 7 are mounted on an elevating frame 2 mounted in the casing 1b. Further, the frame 2 is mounted such that its direction is variable in a 90 deg. arc at a time. Lateral holes different in the direction are excavated without pulling off the casing 1b inserted in the vertical hole. This constitution improves the efficiency of excavation of the lateral hole.

摘要： PURPOSE:To enable the excavation of a large aperture deformed-crose-sectional- area or the like to be efficiently performed by dividing a rotary cutter into a central side cutter and an outer peripheral side cutter, in an enclosed machine type shield excavator, and by driving the respective cutters independently. CONSTITUTION:In an enclosed machine type shield excavator, a rotary cutter on the front surface of a shield is divided into a circular central side cutter 2 and a ring-shaped outer peripheral side cutter 3. After that, the respective cutters 2, 3 can be driven independently with a central side cutter driving gear 14 and an outer peripheral side cutter driving gear 27. Then, both the cutters 2, 3 are synchronously rotated, and are worked under the same condition as that of an integrated cutter, or are rotated with different rotational frequency including reversed rotation, and required excavating function is displayed. As a result, on large aperture excavation, deformed cross-sectional area excavation, or the like, according to various conditions, the efficiency of excavation can be improved.

摘要： PURPOSE:To eliminate fluid leakage and prevent the deterioration of the working environment and the loss of power by providing holes on rotary blocks and closing or opening an opening/closing valve provided on part of them interlockingly with a sliding block when chuck claws are opened or closed. CONSTITUTION:A rotary chuck device is constituted of a sliding block 40 reciprocated by an actuator, rotary blocks 38 and 54 rotated by a motor, and multiple chuck claws 39 and 39. holes 50c, 59, 60-63 through which the fluid sprayed from the tip of an auger 14 passes when the rotary blocks 38 and 54 pass through the auger 14 are provided. An opening/closing valve 77 is provided on part of them, and it is closed or opened interlockingly with the sliding block 40 when the chuck claws 39 and 39 are opened or closed. The leakage of the remaining fluid when the auger 14 is extended can be avoided.

摘要： PURPOSE:To enable reduction of labor by a method wherein an excavating device, a sampling device, and a road cell for testing a road ground strength are mounted to a single self-running type vehicle, and by mounting and demounting the devices to and from an expandable arm mounted to a vehicle, a high-efficient work is effected. CONSTITUTION:A rotary cutter 14 is attached to the lower end of a vertical expandable arm 13 mounted to a self-running type vehicle 7 to excavate a circular ditch in a pavement layer 1. The rotary cutter is replaced with a grasping device 17 is mounted to nip the sample of the pavement layer 1 surrounded with the ditch to take it out. Further, the grasping device is replaced with an earth drill bucket 15 to excavate a stone layer 3 and a bed rock layer 4. The earth drill bucket is replaced with an earth sampling device 16, which is filled with a sample from the bottom of an excavated vertical pit to take it out. A road cell for testing ground strength removably mounted to the arm 13, a water tank 97, and a pump 98 are mounted. This constitution enables reduction of labor required for sampling and allows execution of high-precise ground strength test and sprinkling test.
