摘要： PURPOSE:To enable the easy assembly of a reinforcement member at the predetermined position by assembling the member with the shield propulsion jack forward part inserted into the steel pipe of a reinforcement for concrete. CONSTITUTION:A reinforcement member 1 to be assembled in a shielding machine is constituted with a steel pipe 2 and a reinforcement 3, and divided into a plural number in a circumferential direction. The forward part of a propulsion jack is inserted in the steel pipe 2 of the reinforcement 1 and the reinforcement member 1 is assembled in turn in a circumferential direction. Then, an inner mold frame 4 is assembled on the internal surface of the reinforcement member 1 and a tail frame 6 is used to close a gap at the side of the shielding machine between the drum plate of thereof and the inner mold frame 4. In addition, concrete is filled into the aforesaid gap. Thereafter, quick- curing mortar filled in the steel pipe 2 of the reinforcement member 1 is pressed with the propulsion jack, thereby enabling a shielded drilling and advancing process. Furthermore, after the completion of drilling, the forward part of the propulsion jack is drawn in turn from the inside of the steel pipe 2 and quick- curing mortar is instead filled into the steel pipe 2 in order.

摘要： PURPOSE:To ventilate air containing dust produced on the bottom of a shaft during various kinds of works by sending air into a ring-shaped space produced between the shaft and a guide pipe and emitting the air by way of the guide pipe. CONSTITUTION:A fan 11 supplies a required amount of air into a ring-shaped space 9 from the outside by way of a flow divider 12. The air is turned into a downward blasted air in the ring-shaped space 9. The air, which has reached the lower end of a guide pipe 3, rises upward through the inside from a notched part 3a and is introduced outside the shaft. Dust generated in the ring-shaped space 9 accompanied by the driving of a rotary drilling machine 22 and a breaker 23 during the work, are also discharged outside the shaft through the inside from the notched part 3a. This constitution makes it possible to protect the visual field of a TV camera designed to monitor construction work during various kinds of works, such as drilling or earth retaining in the shaft or serve to protect the health of workers.

SOLUTION: An upstream pipe 7 having a plurality of kneading and carrying blades 9 spirally provided on the inner wall surface is connected to middle and downstream pipes 8, 8 by flanges 7b, 8a, 8b to form a carrying pipe A, and the carrying pipe A is rotatably supported by an inclined load support part E and a plurality of rotating support parts F. A washing valve mechanism C consisting of a housing 31 containing an opening and closing valve and a valve driving part G is provided on the carrying terminal of the carrying pipe A. The thus-formed carrying device is set on an inclined surface, the carrying pipe A is rotated by a carrying pipe driving part having a motor with variable transmission, and concrete is carried in the direction α while kneading so that an aggregate does not separate. After the carrying is ended, the opening and closing valve is closed, washing water is introduced and stored, and the carrying pipe A is rotated to wash away the residue.

摘要： PURPOSE:To enhance the working efficiency of a shaft and the working speed and to enhance the efficiency of excavation by bottoming and fixing the forward end of a guide pipe onto the bottom surface of a drilled shaft, and by moving a gravity type bucket excavator up and down through the guide pipe so as to excavate the ground. CONSTITUTION:A guide pipe 3 is suspended from a guide pipe elevating device (b) supported on a machine frame 6, and a gravity type bucket excavator 14 is moved up and down through the guide pipe 3 so as to carry out preceding excavation and discharge of muck. During this phase, a full swivel type excavating device 16 is provided around the outer periphery of the guide pipe 13 so as to excavate the inner peripheral surface of a shaft 5a, and excavated muck is collected to the center part 33 of the bottom surface and is then discharged by the gravity type bucket excavator 14. Then, the guide pipe 3 is raised, and a spraying manipulator is projected downward from the front end of the pipe 3 so as to spray mortar onto the inner surface of the shaft 5a for sheathing. In this case, rolling wheels 7 are suspended above rails, and are then lifted up by a lift device so as to set the machine frame 6 on the ground surface at the position where the shaft 5a is drilled. Further, the wheels 7 are set onto the rails so as to float up and move the machine frame 6.
