Abstract
【課 題】軌道用不織布の敷設位置決めを容易にすることである。
【解決手段】不織布の表面にレール間隔と同等巾の視認しやすい基準線を描いたもの。
【選択図】 図２[Problem] To facilitate positioning of nonwoven fabric for track.
An easy-to-view reference line having a width equal to a rail interval is drawn on the surface of a nonwoven fabric.
[Selection] Figure 2
Description
【０００１】
【考案が解決しようとする課題】
鉄道の軌道は一般に図１の様な構造になっており、なかには道床と路盤の間に不織布を敷設しての噴泥防止構造、あるいは省力化軌道においては砕石の隙間に填充する材料の漏洩防止材として同様の位置などに不織布が敷設されている。
【０００２】
従来、不織布は無地で敷設時の位置を合わせるための基準線は描いてなかったため、道床交換時等に不織布を敷設する際は、不織布の敷設位置を他の方法で確認しながらの作業であった。
【０００３】
【課題を解決するための手段】
不織布にあらかじめレール間隔と同等巾の２本の線を描いておく。
【０００４】
【考案の効果】
敷設時には不織布の基準線がレールの真下になるところが正常な不織布の敷設位置となる、これで不織布の敷設の位置設定は容易である。
【０００５】
不織布に描かれた線は暗い所でも視認出来る様に、濃い色の油性または水性塗料等で巾広にするとよい。
【０００７】
したがって、鉄道という列車間合や夜間作業といった作業時間の少ない場合やまた暗い所での、軌道用不織布の敷設が容易にできる。

[Problems to be solved by the invention]
Railroad tracks generally have a structure as shown in Fig. 1. Among them, a mud-prevention structure in which a nonwoven fabric is laid between the roadbed and the roadbed, or in the case of a labor-saving track, prevention of leakage of material filling the gaps between crushed stones. A nonwoven fabric is laid at a similar position as a material.
[0002]
Conventionally, the nonwoven fabric was plain and did not draw a reference line for adjusting the position at the time of laying.Therefore, when laying the nonwoven fabric when replacing the roadbed, etc., it was necessary to check the laying position of the nonwoven fabric by another method. Was.
[0003]
[Means for Solving the Problems]
Two lines having the same width as the rail interval are drawn in advance on the nonwoven fabric.
[0004]
[Effect of the invention]
At the time of laying, the place where the reference line of the non-woven fabric is just below the rail is the normal laying position of the non-woven fabric.
[0005]
The line drawn on the nonwoven fabric is preferably widened with a dark oily or water-based paint so that it can be visually recognized even in a dark place.
[0007]
Therefore, it is possible to easily lay the nonwoven fabric for railroads when the working time is short, such as between trains or at night, or in a dark place.
