  The second means of the present invention is characterized in that, in the first means, both the side plates and the bottom plate of the second steel plate cylinder are bonded with an impermeable thin plate.

  According to a third means of the present invention, in the first means, a box portion of a first steel plate connecting cylinder 1 formed by connecting a plurality of second steel plate cylinders arranged at intervals with front and rear plates. The inside is filled with a filler formed by injecting and foaming an impermeable and foamable organic liquid.

  A fourth means of the present invention is characterized in that, in the first means, the upper surface plate and the lower surface plate are steel plates in which both end portions are integrally formed in an “I” shape and an intermediate portion is formed in a “ten” shape. To do.

  According to a fifth means of the present invention, in the third means, the second steel plate cylinder and the first steel plate connecting cylinder have portions that are impermeable to the outer surfaces of the bottom plate, the side plate, and the front and rear plates of the box portion. The thin plates are bonded, and the thin plates are integrally formed.

  According to a sixth means of the present invention, in the first means, the sleeper has a convex or L-shaped cross section, and an insertion hole is formed by attaching an angle to the notch upper portion of the second steel plate cylinder. It is a feature.

  According to the first means of the present invention, the surface of the second steel plate cylinder, which is in contact with the horizontal sleepers, is surrounded by a tightly fitting cylinder portion formed by injecting, filling and curing an impermeable liquid adhesive. Therefore, contact of water and earth and sand is prevented in the ballast, and there is a corrosion prevention effect.

  According to the second means of the present invention, in addition to the effect of the first means, the impervious thin plate is bonded to the surface of the second steel plate cylinder that contacts the ballast. The outer periphery of the metal is free from contact with water and earth and sand, and has a greater anti-corrosion effect.

  According to the third means of the present invention, in addition to the effect of the first means, the inside of the connecting box made of steel plate is filled with the impermeable foaming agent for some reason. This can prevent water and earth and sand from entering.

  According to the 4th means of this invention, in addition to the effect by a 1st means, the 1st, 2nd steel plate cylinder can be manufactured very easily.

  According to the fifth means of the present invention, in addition to the effect of the third means, not only the second steel plate tube but also the first steel plate connecting tube, that is, the contact of water and earth and sand of all sleeper connecting devices. Evacuated and has a greater anti-corrosion effect.

  According to the sixth means of the present invention, in addition to the effects of the first means, a signal cable, a steel rod, or the like can be passed through the insertion hole to reliably protect them.

It is a top view of the present invention. It is AA sectional drawing which lacked a part same as the above. It is a partial expanded sectional view same as the above. It is a BB expanded sectional view. It is an exploded perspective view of the present invention. It is a fragmentary perspective view of the other embodiment of this invention.
