摘要

PURPOSE: A front built-up type inspection path structure of a slope of a road is provided to enable simple construction, to reduce the construction cost, to enable free application to a gradient of the slope, and to reduce the maintenance cost. CONSTITUTION: A front built-up type inspection path structure of a slope of a road comprises upper and lower footstep installation frames(100,100') having plural bolt holes(110,110') in the longitudinal direction; polyethylene footsteps(200) combined to the upper and lower footstep installation frames with inclination; railing posts(300) each having a rail installation part(310) formed in a bent shape to the upper part; intermediate reinforcing rods(400) having plural bolt holes(410) to be closely fastened to bolt holes(330) of the lower parts of the railing posts, to adjust the height of the railing posts; height adjustment fixing anchors(500) closely fastened to the outside of the intermediate reinforcing rods; and rails(600) having plural bolt holes(610) in the longitudinal direction. The upper and lower footstep installation frames are seated on the slope. A slide-preventing part(210) of a thread type is formed to the upper part of the polyethylene footstep. Grid-shaped side parts(220) are formed on the sides of the slide-preventing part. Plural bolt holes(230) are formed in the grid-shaped side parts. The polyethylene footsteps are fastened to the bolt holes of the upper and lower footstep installation frames by fastening bolts(150). A bolt hole(320) is formed in the rail installation part. The intermediate reinforcing rod and the height adjustment fixing anchor are fastened to the bolt holes of the lower part of the railing post by fastening bolts(550). The height adjustment fixing anchor has a square body part(510) and an anchor pin(530) integrally formed. The rail is fastened to the rail installation part of the railing post by fastening bolts(650).
