Furthermore, after the pressure inside of the hollow part 2 is reduced, water is filled in the hollow part 2 to make the water 7 intrude into the crack 6, and the low temperature liquefied gas 4 is filled again, and the opening 3 is sealed and the water 7 is frozen, and the inside of the hollow part 2 is pressurized and maintained to increase the crack 6. This operation is repeated to communicate the inside of the hollow part 2 with the outside with the crack 6, and the filled water 7 is discharged from the crack 6 to the outside of the hollow cylindrical pile 1 to soften the soil of the periphery of the hollow cylindrical pile 1, and a clearance is generated in the periphery of the hollow cylindrical pile 1, and the hollow cylindrical pile 1 is withdrawn.

CONSTITUTION:The device 1 has a carrying- in conveyor 5 and a sending one 6 for sheet metals 4 on both sides of an adiabatic cooling tub 3 containing a low temperature refrigerant 2, and also has a carrier device 12 consisting of a circulating carrier cable 10 which hangs a hanging part 8 of a carrier member 9 on an engaging part of the sheet metal 4, and a driving device 11. The circulating carrier cable 10 goes through an section A where a sheet metal 4 is hung by the carrier member 9, a section B where the sheet metal hung with the upper part tilted forward is carried in a low temperature refrigerant 2, a section C where the sheet metal is shifted on a sending conveyor 6 and released from hanging, and a section D where the empty carrier member 9 is returned to the A section. Thus, the sheet metals 4 are carried automatically, successively and efficiently.

摘要： PURPOSE:To effectively cool a plurality of metal plates so as to be immediately transferred to a processor by suspending a plurality of supporters from a circulating rail of a conveyor device and continuously cooling respective metal plates held by respective supporters while transferring them one after another. CONSTITUTION:Metal plates 5 are transferred by a carrying-in conveyor 9 and carried in a cold refrigerant 2 along a tilted table 23 of a supplying device 10 from a tilt part 3 of a insulated cooling tank 4 while being held by supporters 6. Then, the supporters 6 are delivered to a cooling conveyor 20 at a point E on the way where the supporters are transferred from a point A to a point B along a circulating rail 7, and is cooled during being transferred to a point F. After the supporters 6 are transferred from the point F to the point C through the point B, they are tilted toward a delivery conveyor 11 by a piston 25 of a delivery device 12. Thereby, the metal plates 5 are dropped from the supporters 6 and transferred to the delivery conveyor 11 with being sliding on a tilting plate 26. After that, the metal plates 5 are transferred to the next process, while empty supporters 6 are circulating and returned to the A point through the point D.
