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： PURPOSE:To enable the testing of a water pressure of a pipeline regardless of the size of a pipe or the entry of an inspector by a method wherein a freely movable wheel is driven to be moved within the pipe, positioned with a monitor camera and lighting and a jack is operated to get a rubber ring tight on an internal wall of the pipe for the formation of a closed space. CONSTITUTION:A front base plate 1 and a rear base plate 2 are arranged in the direction of the axis of a pipe and both ends thereof are pierced with four tension bars 12 to be clamped together with a nut 13. Wheels 11 and 12 free to run are pivoted on both the base plates 1 and 2 and moved in the pipe with a drive mechanism so that a detection position is determined with a lighting 7 and a monitor camera 8 mounted on the front of the front base plate 1. Then, an oil pressure is supplied with a hydraulic pipe 16 in the tail to operate a hydraulic jack 6 so that a gradient surface 41 of a front slide cylinder 4 and a gradient surface 51 of a rear slide cylinder 5 are moved outward, causing rubber rings 3A and 3B attached to the base plates 1 and 2 to be pressed onto the internal surface of the pipe. Thus, a closed space is formed at a coupling part or the like desired to test a water pressure thereby enabling the testing of the water pressure.

摘要： PROBLEM TO BE SOLVED: To costlessly widen an installation position of an emergency water storage tank. SOLUTION: Water distributing pipes under a road are made larger in the diameter to serve as a water storage tank T. Length/diameter of this water storage tank T is made 250 or smaller and the inflow/outflow parts are made to form a conical shape gradually expanded/contracted to prevent water from retaining in the water storage tank T. The water storage tank T and the conical parts are made of pipes a1 , a4 of existing JIS standards. A service pipe Q is provided with a bypass to easily supply water. A water supply pipe E is extended from the low position of the water storage tank T to the edge of a road R to supply water from the water storage tank T without hindrance to traffic.

摘要： PURPOSE:To aim at replacing an existing oil pipe with a new pipe without affecting the new pipe by replacing the old pipe with a inner with the use of an excavator, by introducing the new pipe into the liner while applying a film on the inner surface of the liner, and by pulling out the liner after a curing agent filled in the gap between the liner and the new pipe being cured. CONSTITUTION:A liner 1 serving as a protecting sleeve for a new pipe 6 is attached to the rear part of an excavator including a barrel having a diameter greater than that of an existing old pipe 4 embedded in the ground. When the excavator is introduced onto the oil pipe 4 so as to replace the old pipe 4 with the new pipe 6, a cylindrical film member 5 is applied in the inner surface of the liner 1 over the entire length of the latter. The new pipe 6 is introduced into the film member 5 while a fluid curing agent 7 is filled between the gap between the film member 5 and the new pipe 6, and then the liner alone is pulled after the agent 7 is cured. As a result, it is possible to know the existence of a pipe line only by excavating the ground up to the position of the film member, thereby it is possible to prevent an accident such as breakage of a pipe line during another excavation work.

摘要： PURPOSE:To aim at reducing the frictional resistance during advance of a new pipe by attaching the new pipe to the rear end of an excavator having a barrel with a diameter greater than that of an old pipe, and by coating an antifriction composition on the surface of the ground or the inner peripheral surface of the old pipe. CONSTITUTION:A new pipe 11 is attached to the rear end of an excavator 12 including a barrel having an outer diameter greater than that of an existing old pipe 1 embedded in the ground. When the forward end of the excavator 12 is introduced onto the old pipe 1 so as to replace the old pipe with the new pipe 11, an antifriction material is coated on at least one of the surface of the ground G and the inner peripheral surface of pipe pieces 15 of the old pipe 1 to be crushed with which the outer periphery of the new pipe on advance makes contact. As a result, the workability and economy of the replacement of the old pipe with new one are enhanced. Further, the distance between an excavation starting position to an excavation stopping position can be prolonged so that it is possible reduce the number of vertical shafts, thereby it is possible to reduce traffic barriers.

摘要： PROBLEM TO BE SOLVED: To provide a cast iron-made water collecting pipe, enabling prevention of multiplication of rust in a sump to keep collecting capability by mounting a rust-proof sleeve in the sump.
SOLUTION: In fitting the rust-proof sleeve 5, a projecting part 8 of the rust-proof sleeve 5 is abutted to the sump 4 of the cast iron-made water collecting pipe 1, and pushed into the sump 4. The outward projecting part 8 of the rust-proof sleeve 5 is reduced in diameter and simultaneously set into the sump 4 by push-in force through the action of the tapered projecting part 9. When the sleeve is further pushed in, the outward projecting part 8 is put out of the sump 4 of the cast iron pipe 1 and released from the sump 4 to be restored to the initial state. Thus, the outward projecting part 8 is engaged with the cast iron pipe 1, whereby even if rust is generated in the inner peripheral surface of the sump 4, the bore diameter of the sump 4 can be ensured.
