Description

  The present invention relates to a cable trough.

  Cables for communication and power transmission along the railroad track are stored in cable troughs laid along the railroad track, and these cable troughs are generally made of concrete and have left and right bottom walls. The trough body is formed with side wall portions rising on both sides, and a lid that closes the upper surface opening of the trough body. In addition, the length of one trough main body is about 50 cm-about 100 cm, and several cable troughs are laid in the connection state by the part according to the length of a cable.

  By the way, the railroad tracks are equipped with ballast (gravel) for the purpose of cushioning and soundproofing the rails and sleepers, but this ballast collapses due to vibrations when passing through the train and moves to the side. However, the cable trough is buried, and it is difficult to dig up the cable trough buried in the ballast each time, for example, when replacing an aged cable. In many places where the cable troughs are laid, heavy machinery cannot be put in. Therefore, the ballast removal work is performed manually.

  Therefore, conventionally, in order to solve the above-described problems, a cable trough (hereinafter, a conventional example) having a ballast stop function disclosed in, for example, Japanese Patent Application Laid-Open No. 2015-211586 has been proposed.

  In this conventional example, a ballast stopper wall is integrally formed at either one of the upper end portions of the left and right side wall portions constituting the trough body.

  Therefore, movement of the ballast can be prevented by the ballast stop wall, and the cable trough can be prevented from being buried by the ballast as described above.

JP2015-211586A

  However, the conventional example has the following problems.

  That is, even in the same cable trough laid along one railroad track, a place where a ballast stop wall is necessary and an unnecessary place (for example, a place where the ballast does not collapse or an operator performs another work If there is a protrusion in the area, there will be an obstacle to the work), the conventional example alone cannot meet this requirement, and an existing trough body without a ballast stop wall must be prepared separately.

  Also, in the conventional example, when storing the trough body after storage or when transporting it to the laying place, the ballast stop wall is an obstacle to stacking and packing products together, and the ballast stop wall touches something. It may be damaged.

  In addition, the conventional example requires a dedicated mold for molding the trough body having the above-described shape, which increases costs.

  The present invention provides an unprecedented and highly practical cable trough that solves the above-mentioned problems.

  The gist of the present invention will be described with reference to the accompanying drawings.
