摘要： PROBLEM TO BE SOLVED: To easily store a sleeper in a stacking shape, and to reliably prevent a movement by a train load after being laid by projecting one or plural projections on the lower end surfaces on both ends of the sleeper. SOLUTION: Plural projections 2, 2 are respectively projected almost just under rail fastening parts 1a, 1a of the lower end surfaces on both ends of a sleeper 1. These projections are formed in an inverse truncated cone shape or a inverse truncated pyramid shape such as gradually becoming small in a diameter in the lower end direction or a bar shape continuing by the prescribed length in the direction perpendicular to the axis of the sleeper 1. Then, when storing the sleeper 1 in a stacking shape, since the projections 2 operate as a sticker, the sleeper 1 can be stored in a stacking shape without separately using the sticker. When used in a ballast roadbed, since the projections 2 operate as an antislipping member by biting into ballast, dislocation by a train load can be prevented.

摘要： PROBLEM TO BE SOLVED: To reduce the number of power collectors and the noise produced when a plurality of train sets each composed of one or a plurality of serial rolling stocks are run in a state where the make-ups are connected in parallel with each other, by connecting the power cable of one train set to that of the other train set and supplying electric power from one set to the other. SOLUTION: Another train set B composed of six rolling stocks #9-#14 is connected in parallel with one train set A composed of eight rolling stocks #1-#8. After connection, the cable connecting device 5 housed in the leading stock #9 of the make-up B comes out of the stock #9 and is connected to a cable connecting device 5 housed in the leading stock #8 of the set A. Consequently, the power collector 2 and transformers 3 of both sets A and B are mutually connected and the sets A and B are collectively fed with electric power. Therefore, the installed number of the current collecting devices 2 can be reduced as compared with another set composed of the same number of rolling stocks and the noise produced when a plurality of train sets are run in a state where the sets are connected in parallel with each other can be reduced.

摘要： PROBLEM TO BE SOLVED: To maximize the effect of shear reinforcement by clamping and fixing a connecting material by anchors installed to bearing materials at four corners and constraining a reinforced concrete pole by pole corner sections. SOLUTION: Bearing materials 10 such as L-shaped sectional angle steel are mounted at the four corners of the reinforced concrete pole 1, in which walls, etc., are set up to a periphery, extending over the height of the pole. The bearing materials 10 are connected by connecting materials 11 such as steel bars among the bearing materials at four corners and each bearing material is surrounded, the connecting materials 11 are clamped by anchors 12 applied to the bearing materials 10 and the bearing materials are fixed, and the reinforced concrete pole 1 is constrained only at the corner sections. The connecting materials 11 may also be fastened directly by the bearing materials 10. Simple exterior wall materials may also be fitted for protecting reinforcing sections and for protecting simple sections as required after reinforcement. Accordingly, when a station is set to the poles of a viaduct, the removal range is inhibited extremely while large deformation performance can be ensured by constraining the connecting materials from the four corners of the poles.

摘要： PROBLEM TO BE SOLVED: To form the even hardening concrete while restricting the change with age of the high flow concrete by arranging partitioning plates inside of a long size element to be constructed so as to partition the inside into plural spaces for concrete placement. SOLUTION: Plural partitioning plates 2 are arranged inside of an element to be constructed formed of square steel pipes or the like so as to divide the inside into plural spaces V1-V4 for concrete placement, and concrete pressure feeding pipes P2-P4 formed of a spiral pipe having a low pressure resistance are arranged. A porous plate of punching metal or the like is arranged in the highest part of the partitioning plate 2 so as to form ventilation holes 8. High flow concrete is placed into the space V1 from a supply pipe 10 through an end plate 9, and the supply pipe 10 is connected to pressure-feeding pipes P2-P4 in order so as to place the high flow concrete into the spaces V2-V4. With this structure, filling distance to be required per each time is shortened so as to restrict the change with age of the concrete, and generation of part left as it is not filled with concrete is prevented so as to form the even hardening concrete.

The pile top member 11 comprises a coating part 13 to be engaged with a pile top of a steel pipe pile with a clearance 15, and at least one injection port 4 is formed. A bolt hole 3 for adjusting the clearance 15 is optionally formed for temporarily fixing a bolt. An end part 18 of the clearance 15 is sealed by the welding, mortar, a rubber O ring or the like to form a seal part 7. Then an adhesive agent 6 is injected into the clearance 15 from the injection port 4, and hardened. The viscosity of the adhesive agent 6 is below 20,000 mPa.s, and the adhesive agent is hardened by mixing a polymerization initiator and a hardening accelerator. Two agent-type cold hardenable acryl adhesive agent is preferred. Whereby the steel pipe pile and the pipe top member can be easily connected, and the execution time can be remarkably shortened.
