摘要： PROBLEM TO BE SOLVED: To solve a problem of insufficient earthquake resistance of a conduit, i.e., insufficient stretchability of the same in both directions, the conduits being laid under the ground by pressing the rear thereof. SOLUTION: There is provided a joint for use in an earthquake resisting pipe jacking method, which is constructed by interposing a propelling force transmitting ring 3 between a pressing flange 11 sheathing an insertion port 1 of a pipe 10A to be fitted, and a side end face 21 of an opening of a receptacle 2 of the other pipe 10B, whereby propelling force is transmitted by the ring 3 to form the conduit. After completion of the propulsion, the ring 3 swells and melts to lose the compressive strength thereof, and the joint have an annular dissolved layer R which allows expansion and contraction over a peripheral surface thereof. Alternatively, the ring 3 is dissolved and disappeared to thereby form a void over the peripheral surface thereof. The ring 3 may be formed of any of a water-soluble polymer, an alkaline water-soluble polymer, an acid water-soluble polymer, especially poly(vinyl alcohol) and its derivative, poly(N-vinyl pyrrolidone) and its copolymer, copolymers of various vinyl monomers containing a carboxyl radical, a sulfonic acid radical, an amino group and their salts, and combinations between any of these materials, other polymers, and fillers. The materials thus prepared are of high practical value.

摘要： PROBLEM TO BE SOLVED: To provide an earthquake resistant pipe fitting with a socket outside portion 2b having improved breaking strength and flexibility.
SOLUTION: One splitting tight lock ring 13 is movably fitted into an annular groove 15 of a spigot 1 and a lock ball 11 is provided in an annular groove 12 of the socket 2, and the lock ball and the lock ring abut with each other at their circular faces. In this way, two lock members exist where the lock ball has a sufficient diameter to abut on the lock ring and the groove storing the lock ball has a sufficient depth to make the spigot pass when storing it and to absorb the larger diameter of the lock ring. Thus, the socket side lock member storage groove can be shallower than that of a PII type fitting, and so the pipe thickness of the socket in its groove area can be thicker, thereby achieving higher breaking strength. When the spigot is bent in the socket, its abutting point is moved along the circular face of the lock ball to allow the bending, therefore achieving smooth bending.

摘要： PROBLEM TO BE SOLVED: To smoothly perform blocking work of a start shaft side end of a sheath pipe. SOLUTION: A construction method for pipe-jacking by letting a new pipe 2 float by buoyancy is adopted, and only a cap 30 is first fitted into the sheath pipe 1 to block the start shaft side end of the sheath pipe at this time. When an arrival shaft side end of the sheath pipe 1 is blocked, a scope of selection of work for pouring a buoyancy material into the sheath pipe 1 is enlarged to improve work efficiency. When fitting a tip of the new pipe into the cap, the most leading new pipe is fitted while preventing insertion of the cap into the sheath pipe and then the new pipe is inserted into the sheath pipe together with the cap. Even if the cap is first fitted into the sheath pipe, fitting is not performed well if the cap is inserted into the sheath pipe. A divided-into-two ring 35 is adopted as an insertion prevention means of the cap into the sheath pipe 1, a screw is screwed into a screw hole around it, and its tip is abutted on an outer peripheral face of the cap to attach the ring 35 to the cap 30.

摘要： PROBLEM TO BE SOLVED: To smoothly discharge buoyant material with low cost and simple structure. SOLUTION: When a new pipe 2 is connected and inserted in order in a sheath pipe 1 laid under ground, both ends of the sheath pipe 1 are blocked and buoyancy is given to the new pipe 2 by buoyancy material "a" in the sheath pipe 1 to reduce friction between the new pipe 2 and the sheath pipe 1. A covered cylindrical body 23 is fitted in another end of the sheath pipe 1, the buoyancy material "a" is made over flow from a long hole 26 long in a cylindrical shaft direction of the sheath pipe 1 of the side surface to keep a level of the buoyancy material "a:" in the sheath pipe 1 constant. An over flow structure has a simple structure and cost thereof is low. If a hole for overflow is the long hole 26, an edge of the overflow is elongated and discharge is made smooth. If the buoyancy material is discharged smoothly, the new pipe does not impinges on a sheath pipe inner surface and the new pipe is jacked smoothly. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To increase breaking strength of a socket part 2b outside a lock ring 11 and to perform a jacking method with its pipe joint. SOLUTION: Lock rings 11, 13 are disposed on both insertion piece 1 side and a socket 2 side. Locking faces of the socket-side lock ring 11 and an end face 12b outside its groove 12 are elliptical curved faces having the same curvature. By having the same curvature, the elliptical curved faces are brought into surface-contact with each other to transmit a force through whole contact faces, so that a range of the force received by the socket 2 through the lock ring 11 becomes wide to reduce stress per unit area. Abutting faces 11a, 13b of the lock rings 11, 13 are formed in linear tapered faces tapered on a pipe axis side toward the outside in a pipe axial direction of the socket 2. By the linear tapered faces, even if there is misalignment or outer diameter tolerance between the insertion piece and the socket 2, the misalignment or the like is absorbed by movement of the abutting faces in their contact face directions and transmission of the force from the insertion piece 1 to the socket 2 is always through the faces, so that the stress concentration is hard to occur.

摘要： PROBLEM TO BE SOLVED: To efficiently install a conduit penetrating a levee body by a non-open-cut method and to provide a complete water seal property. SOLUTION: Cement slurry S blended with a hardening accelerator is injected from an injection nozzle 21 guided from the top end 11 of the levee body 1 and substituted to form an impervious wall main body 3 having the desired height and width. A propulsion pipe 5 fitted with a drilling machine 7 with the diameter slightly larger than the pipe diameter at the head is thrust into the levee body 1 horizontally continuously from a vertical shaft 4. When the propulsion pipe 5 reaches a planned pipe crossing the impervious wall main body 3, a plurality of circular impervious bags 61 each having a barrel section impermeable to a grout material G and moisture and a sewn section permeable to only the air with a fixed pressure or above on the whole periphery are expandably folded and stored. An impervious propulsion pipe 6 opened with a grout injection port 62 is connected between the circular impervious bags 61, and normal propulsion is continued to form the conduit penetrating the levee body 1. The grout material G is pressed into the circular impervious bags 61, the air compressed in the bags 61 as the filling progresses is discharged from the sewn sections and expanded to form circular gaps C into closed sealed spaces. The grout material G is pressed into the sealed spaces from the grout injection port 62, the gaps C are filled regardless of size and shape, and the conduit having an excellent water stop property is installed by the non-open-cut method.

摘要： PROBLEM TO BE SOLVED: To reliably prevent buoyancy material from leaking out even if a joint part of the new pipe swells when a new pipe is given buoyancy and is jacked and inserted in a sheath pipe 1. SOLUTION: A water shut off member 12 on one end of the sheath pipe is formed as one unit of rubber, and consists of a cylindrical part 12a fixed on an inner surface of the sheath pipe 1 by a machine screw, a flap 12b facing an axial center of the sheath pipe on an inner circumference whole surface, and a solid cross section round rubber ring 12c of larger diameter than a tip end thereof on a tip end whole circumference of the flap 12b. The flap has normally flexibility and flexibly correspond to change, fluctuation of size (diameter) of the new pipe sliding in the annular shape part of the flap. Then since a solid cross section circular rubber ring is larger in a diameter than a flap tip edge, the flap is not easily influenced by bent of the flap, sure press contact to the new pipe outer circumference surface is maintained even if the flap is deformed to secure water tightness.
