摘要： PROBLEM TO BE SOLVED: To discharge a pig fitted with a brush stopped within a pipeline by remote operation. SOLUTION: A hand 6 equipped with a grasping pawl 23 capable of grasping the hook part (f) of a pig P is attached to the leading end part of the cable 31 of a pig drawing winch and a cable clamp 12 and a hand clamp 13 are operated to draw in the cable 31 from the lower part of the main body 1 of a pig discharge device 10 to grasp the same and the main body 1 is allowed to run to the pig P by a thruster 4 to grasp the hook part (f) by the grasping pawl 23 on the hand 6 and the cable 31 is taken up to be moved to a manhole. The cable 31 is detached from the main body l to discharge only the pig discharge device 10 and, subsequently, by discharging the pig P on the ground, the pig can be discharged from a pipeline 40 without allowing a worker from entering the pipeline 40.

摘要： PROBLEM TO BE SOLVED: To inject water of a high pressure to the inside surface of a chimney concentrically for a prescribed time across its circumferential direction by attachably and detachably providing one of the fountain ports of a swiveling joint pipe with a bent nozzle and providing the other fountain ports of the swiveling joint pipe exclusive of the fountain port provided with the bent nozzle with a straight nozzle. SOLUTION: The swiveling joint pipe 13 is fitted coaxially and swivellably onto the outer peripheral surface of an ordinate pipe 12 via bearings 14. The fountain ports 13a to 13d communicating with a water flow path 12b are formed in the symmetrical positions on the outer peripheral surface around the axial center thereof. The fountain port 13d among the fountain ports 13a to 13d is provided with attachably and detachably with the bent nozzle 17 so as to intersect orthogonally with the axial center of the swiveling joint pipe 13. The fountain ports 13a to 13c exclusive of the fountain port 13d provided with the bent nozzle 17 are respectively provided with straight nozzles 16. As a result, the concentric injection of the water of the high pressure to the inside surface of the chimney for the prescribed time is made possible.

摘要： PROBLEM TO BE SOLVED: To make it possible to develop nozzle bodies and to inject high- pressure fluid from near the inside wall surface of a pipe at the time of shell removal work by providing the device with the nozzle bodies and guide bodies which are developed or folded by the force of the high-pressure fluid and springs and wheels in contact with the inside wall of the pipe. SOLUTION: When the high-pressure fluid is introduced into a cylinder via the hose 9-1, pistons 34 extrude output shafts 32 by overcoming the energizing force of the springs 33 and turn rods 31 to bring, the wheels 30 of the guide bodies 8 into contact with the inside wall of the pipe 2. The nozzle bodies 7 are similarly turned as well. When the shell removal of the inside wall of the pipe 2 is needed, the nozzle bodies 7 and the guide bodies 8 are placed along the main body 6 and the pipe cleaning device is passed into the flowing water from an opening while a cable and the high-pressure hose are held attached to the device. When the device descends down to the desired position, the high-pressure fluid is supplied to develop the nozzle bodies 7 and the guide bodies 8, thus bringing the wheels 30 into contact with the inside wall of the pipe 30. The high-pressure fluid is spouted from the nozzles 24 and is blown to the inside wall of the pipe 2.

摘要： PURPOSE: To surely clean the inside of the tube of a shock tunnel and to well maintain the operability and reproducibility of the shock tunnel by a method in which after a small-sized traveling device being made to travel in a tube to transfer a drive transmission part from one end to the other end of the tube, a cylindrical object is extracted through the drive transmission part. CONSTITUTION: After the arrival of a small-sized traveling device 8 at the end of a tube on the opposite side, a drive transmission part 4 is removed from the traveling device 8, and an extraction driving device 10 of a cleaning tool 1 is fixed on the end surface of the tube. The driving device 10 is constituted by installing a winding drum 6 for taking up the transmission part 4, a motor 5 for rotating the drum 6, and a belt 22 which transmits the drive of the motor 5 to the drum 6 on a base 7. The transmission part 4 which was connected to the traveling device 8 is attached to the drum 6, the motor 5 is operated, and the transmission part is taken up. Then, the cleaning tool 1 makes a cloth surface contact the inner surface of the duct to drive the inside of the duct to wipe off dirt on the inner surface of the tube.
