摘要： PURPOSE:To make an underground pipe coverable by drawing a tubular impermeable film out of a storage room to be installd in the rear of a shield machine in the point midway in propulsion embedding of the underground pipe in a jacking method. CONSTITUTION:A tubular impermeable film storage pipe 2 and a short pipe member 4 to be composed of installing each movable cylinder 8 at each proper interval in the circumferential direction both are connected to the rear of a shield machine 1 in order. In the case where this impermeable film 3 to lee drawn out of a storage pipe 2 during propulsion is broken down, or in the case where necessity is cause to draw the film 3 out of the storage pipe 2 anew otherwise, the movable cylinder 8 is shifted in the outer diametral direction and thereby this film 3 is pressed to the peripheral ground under pressure. In this state intact, an anchor 9 is driven into the ground through an inner part of the movable cylinder 8, whereby the impermeable film 3 is secured tight, and using the fixed part as a fulcrum, the impermeable film 3 is drawn out according to the jacking motion of an underground pipe.

摘要： PURPOSE:To improve the passing performance of concrete by inserting attendant pipelines in elongated holes, provided in rib bands, surrounding the outer periphery of an inner steel pipe, in such a way as to be extended circumferentially piercing the longitudinal direction of the inner steel pipe, and connecting the pipelines to each other by the connecting parts provided at both ends. CONSTITUTION:A slidable attendant pipeline 4 is inserted in the elongated holes of rib bands surrounding inner steel pipes 3, 3', and the attendant pipeline 4 is slid forward in the propulsion direction. A first connecting part at the propulsion direction front end of the attendant pipeline 4 is connected to a second connecting part at the propulsion direction rear end of the attendant pipeline 4 of front double propulsion pipes 1, 1' for burying. The attendant pipelines 4 are connected directly to each other to maintain the passing performance of concrete or the like desirably. The elongated holes for inserting the attendant pipeline 4 are extended in the circumferential direction of the inner steel pipes 3, 3'. Accordingly, even if slight dislocation is generated between the connected attendant pipelines 4, 4', this dislocation can be easily corrected to connect both atendant pipelines 4, 4 easily.

摘要： PURPOSE:To facilitate an injection work of unguent between the outer circumferential face of a double tube and natural ground while propelling the double tube consisting of an inner tube and an outer tube. CONSTITUTION:A duct B laid by propelling a double tube A is previously divided into a plurality of sections having predetermined length. When an excavator 11 following the double tube A is propelled, a tube 3 provided in the double tube A is selected according to the section in response to the tube A and connected to the tube A, and the selected tube 3 and an unguent force feed pump 14 are connected together through a hose 13. Consequently, in the case of the double tube A in response to the section set close to a starting shaft (n) pieces of the tube 3 are connected to the pump 14. Accompanying propulsion of the double tube A, the pump 14 is driven, and the unguent is injected from all the tubes 3 connected to the pump 14. Hereby, it is unnecessary that an unguent injection member is moved in the double tube A so as to infect the unguent, and hence the work is facilitated.

摘要： PURPOSE:To prevent a reinforcing cage from floating by fixing the reinforcing cage to a centrifugally molded drum shell or a marginal form using a form tie to place concrete. CONSTITUTION:The hook like fixing part 5e of the internal bolt 5d of a form tie 5 is fixed to a reinforcing cage 3 by pressure-bonding or welding. The internal bolt of the form tie 5 is then thrusted into a truncated cone member 5a, and the truncated cone member 5a is brought into close contact with the sheathing board of a drum 10 and fixed to the drum 10 by a fixing bolt 5b and a setscrew 5c. The reinforcing cage can be fixed easily into an appropriate position by using the form tie.

摘要： PURPOSE:To enhance construction efficiency by installing a sleeve pipe line an in open shield method or the like and welding an connecting steel pipes one by one at a launcher pile side and pulling the welded pipes into the sleeve pipe line. CONSTITUTION:A sleeve pipe line 5 is constructed with hume pipes 4 or the like based on an open shield jacking method. A first steel pipe 8 is installed to a launcher base in a launcher pile 6. After it is aligned and weld-tested and coated, the pipe is pulled into the rear end of the sleeve pipe line 5 by a definite length with a wire 12 extended from a winch 11 installed to the open shield machine 1 side. Then, a second steel pipe 8 is lowered. After the tip of the second steel pipe 8 is welded with the rear end of the first steel pipe, the steel pipe is pulled into the sleeve pipeline 5 once again with the winch 11. Then, similar operations are carried out until this pipeline 13 is formed. Both the sleeve pipeline 5 and the steel pipe line 13 are constructed simultaneously. This construction makes it possible to shorten construction time dramatically and reduce construction cost, and what is more, to prevent the generation of damage, zigzag or the like. Furthermore, since protected..with the sleeve pipes, the safety of gas pipelines can be enhanced with this method.

摘要： PURPOSE:To manufacture a device small in the peripheral direction and miniaturize it by forming a circular projection serving as a piston in a void between the outer tube of a blocking member and an expansion film, allowing the blocking member to function as a cylinder, and feeding the fluid of a fluid operation chamber into an airtight space via the first and second inflow holes. CONSTITUTION:A circular projection 12 is provided at the tip section of a tube body 11. A fluid pressure operation chamber 5' is formed on the circular projection 12, and a pressure receiving face 4a formed on a blocking member 1 exists on the fluid pressure operation chamber 5'. Front end sections of the outer tube 2 and inner tube 3 of the blocking member 1 are connected by a cover member 4, and a cylinder chamber 5 is formed in the space. A fluid passage 19 is bored on the tube body 11, and the second inflow hole 20 is formed through the tube body 11. The first inflow hole 6 and a recessed groove 7 are carved at the tip of the inner tube 3. The recessed groove 7 and a protruded member 26 constitute a stopper. The blocking member 1 is coupled with the tube body 11. The device can be miniaturized, and it can be used for a small- diameter pipe.
