摘要： PURPOSE:To make it possible to bring an accelerating agent into an accelerating agent housing tank with simplicity and safety as well. CONSTITUTION:The tip of a hose 10 connected to a loaded pipe 6 is inserted into an envelop which houses an accelerating agent while the tip of a hose 12 connected to a suction pipe 4 is connected to a suction pipe of a vacuum blower 13. The housing tank 1 is placed in an enclosed state by closing a valve installed to a supply pipe 14 of the accelerating agent supplied by a carrier screw 9 and then ball valves 7 and 8 for the suction pipe 4 and the loaded pipe 6 are opened. When the vacuum blower is operated, the pressure in the housing tank is turned negative. A suction force produced by this megative pressure forces the accelerating agent in the envelop 11 to be brought into the housing tank.

摘要： PURPOSE:To avoid 'gripping' by expansion pressure by connecting the bearing of a driving shaft to an engaging body capable of being detachably engaged with the internal surface section of an existing segment ring through a cutter- face propulsive jack. CONSTITUTION:A cutter face 21 acquires driving force and excavates soil at a constant distance by forward moving (elongating) a cutter-face propulsive jack 60, and a shield skin plate 1 is pushed out forward by advancing (elongating) a skin-plate propulsive jack 70 with the excavation. When excavation is conducted at the constant distance, the propulsive jack 70 is retreated (shrunk), and a segment ring is assembled into an air gap generated in the rear plate 1 of the propulsive jack 70. The segment ring is assembled completely, and excavation is performed while extending the propulsive jack 60 and the propulsive jack 70 again. When expansion pressure is increased extremely, the propulsive jack 60 is contracted and excavation is executed while retreating the cutter face 21 or the cutter face 21 is backed at a fixed distance and excavation is conducted again.

摘要： PURPOSE:To make it possible to carry out assembly, disassembly and movement of a form in a short time and easily by constituting an inversion type form moving device capable of moving form bodies separately by a form moving body mounted on a plurality of form bodies to be connected and laid. CONSTITUTION:A form moving body 20 constituted of a horizontal base frame 20a and an arch shaped frame 20b is placed on plurality of form bodies 10 laid by pivoting and connecting on connecting arms 11. After the concrete placed to the lower surface is solidified, a tractive rope 28 of a winch 27 is hung on the form body 10 in the furthest left end to wind up, and the form body 10 is turned to invert. After that, a transferring chain 26 is connected to the form body 10, and after the pivots of the arms 11 are removed, the chain 26 is turned by a driving source 25. In addition, the form body 10 is moved to the right end under the guidance of the frame 20b, and it is pivoted on the form body 10 in the furthest right end to push it down as a shaft. That method is subsequently repeated to provide the form bodies... to new positions on the right side.
