摘要： PROBLEM TO BE SOLVED: To provide an apparatus for spreading the width of an existing tunnel, which enables safe width-spreading work in a short construction period while keeping the tunnel in service conditions. SOLUTION: The apparatus is formed of a protector 2 which has its inner space penetrated in a tunnel axial direction, and a movable work frame 3 which is shorter in length in the tunnel axial direction than the protector and arranged astride the protector. The work frame is movable in the tunnel axial direction independently from the protector. Alternatively, the protector may be movable in the tunnel axial direction independently from the work frame.

摘要： PROBLEM TO BE SOLVED: To remove marking works prior to driving works by detecting the movement of a locking-bolt driving device along a guide rail, the distance in the vertical direction of a slope, and the quantity of the traveling of a truck, the distance in the horizontal direction of the slope. SOLUTION: A chain 8 is stretched in the longitudinal direction of a guide rail, a gear 12 is installed in the same axis as a holding-down sprocket 11 engaged with the chain 8, when a sliding base (a driving device) can be moved along the guide rail by rotating a sprocket 9 engaged with the chain 8 by a hydraulic motor 10 mounted on the driving device, and the number of teeth 13 of the gear 12 turned with the movement of the sliding base is counted by a proximity switch 14, and the movement of the sliding base (the driving device) is detected. The number of teeth 16 of a gear (a sprocket) 15 which revolves together with the rotary movement of a crawler is counted by a proximity switch 17, and the quantity of traveling of a truck is detected.

摘要： PURPOSE: To improve operability and quality by providing at a piston type concrete pump and a screw feeder type accelerating agent feeding device with respective sensors and computing and displaying a concrete delivery amount and an accelerating agent addition ratio based on data therefrom. CONSTITUTION: During spraying of concrete, stroke end sensors 77L and 77R for a concrete pump detect arrival of the stroke end of a piston. The number of revolutions of a screw rotary shaft is then detected by a sensor 87 for detecting the number of screw revolution of an accelerating agent feeding device. A computer 10 computes a concrete delivery amount and an accelerating agent addition ratio based on detecting data from the sensors 77L, 77R, and 87 and a correction value from a correction value inputting apparatus 21, and displays a computing results at a display part 9. This constitution recognizes a state by an operator only by watching the display part without a need to read and calculate a delivery amount according to a corresponding graph, and prevents wasteful consumption of a raw material and improves strength and appearance.

摘要： PURPOSE:To enable rapid movement even at a narrow place and a bent place, and to improve operating efficiency by forming the rear wheels of a traveling truck in the left and right unnecessary independent wheels of a rear axle and installing a cylinder garnish rim between the rear wheels in an elevation-able manner. CONSTITUTION:The unnecessary independent rear wheels 18 of rear axles, into which hydraulic motors 17 are incorporated, are mounted to a traveling truck. A concrete pump 14 with a hopper 20, a discharge opening 22, a changeover valve 23, etc., is set up, and cylinders 21a, 21b for force-feeding concrete are fixed to a cylinder garnish rim 24 between the rear wheels 18, 18. The garnish rim 24 can be lifted and lowered by hydraulic cylinders 26 for elevating and bringing down the pump. The pump 14 is lowered toward a rear lower section on work by the expansion of the cylinders 26, and lifted toward a front upper section on traveling. Accordingly, distances from the rear wheels 18 to the rear end of the pump 14 are shortened, and the movement and radius of gyration of the pump can be reduced.
