PURPOSE:To fix a pole easily and ensure durability by filling crushed stone and ballast between railway lines with a setting agent, and fixing and stabilizing monolithically the crushed stone and ballast together with the safety fence pole. CONSTITUTION:A strapped joint is applied to the lower part of a pole 2 to drive the strapped joint with a hammer to the extent until the head thereof comes out from the surface of the crushed stone and ballasts 1, and the work is successively carried out. After that, the setting agent is filled around the lower part of the pole 2 from the surface of the crushed stone and ballasts 1. At that time, in order to prevent the outflow of the setting agent, partitions, such as sandbags, etc., can be buried in the crushed stone and ballasts 1. T hen, those works are successively carried out, and after the completion of filling of the setting agent around the lower parts of the specific number of poles, the remaining pole main bodies 4, after the poles are divided into up ad down parts, are respectively driven. After that, bolts 5 of the lower parts of the poles 2 are fastened to connect, and ropes 7 are provided to rope mounting metal fixtures 6 to complete the installation of a safety fence between the lines. |
