摘要： PROBLEM TO BE SOLVED: To make it possible to easily and surely forming a thermally sprayed film on the inner peripheral surface having ruggedness of a small-diameter tube. SOLUTION: A compressed air stream A is passed to the circumference of a flame F formed by burning a gaseous mixture composed of gaseous fuel and an oxidizing agent. A thermal spraying wire 17 is supplied toward this flame F and a globule is formed by melting this thermal spraying wire 17 by the heat of the flame. While this globule is finely divided by the compressed air flow A, the globules are accelerated and are sprayed onto a step part 21 on the inner periphery of the small-diameter tube 20, by which the thermally sprayed film is formed on the surface of the step part 21. The thermal spraying angle 6 is made at an angle of 90 deg. or approximate to 90 deg. and the thermal spraying wire 17 is continuously supplied from the outer side of the compressed air A toward the flame F.

摘要： PROBLEM TO BE SOLVED: To obtain a filler having high fluidity while contriving the effective utilization of the earth generated in water purification.
SOLUTION: In the filler, total weight of the earth generated in water purification and monmorillonite as a water-retaining agent : 0.05-5.0, metal powder as a foaming agent : 0.00005-0.001, ligninsulfonate as a fluidizing agent : 0.0015-0.05 and water 1.0-10.0 are mixed to cement : 1 by weight. A bleeding problem is solved by capturing an incremental amount of moisture by mixing the water-retaining agent. Fluidity is improved by dispersing the cement and the foaming agent or the like by mixing the fluidizing agent. A filler layer having many shape-retaining void layers is obtained by the foaming agent. When the void of the filler layer is increased, mechanical strength such as compression is deteriorated. When compressive strength is 0.1-1.0 N/mm
2 by adjusting a mixing ratio of the water-retaining agent or the like, the expansion and contraction of a fitting due to the generation of an earthquake are smoothly performed, and when the compressive strength is 1.0-2.0 N/mm
2 , the filler the same as a conventional one is obtained.

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.
