Fabricated bottom-fixing temporary guardrail for highway and construction method of fabricated bottom-fixing temporary guardrail
According to the highway assembly type bottom fixing temporary guardrail and the construction method, bottom fixing stand columns are arranged at equal intervals in the highway direction, and the lower ends of the bottom fixing stand columns stretch into column holes in the roadbed ground and are fixed through a plurality of tensile pins; the lower ends of the tensile pins are fixed to the bottoms of the column holes through cement paste, the upper ends of the tensile pins are detachably connected with the bottom fixing stand columns, and waste geotechnical materials are filled in annular spaces between the bottom fixing stand columns and the column holes. The heights of the upper ends of all the bottom fixing stand columns extending out of the roadbed ground are equal, the outer wrapping plate forms a closed cavity which surrounds all the bottom fixing stand columns and extends in the highway direction, the internal transverse partition plates are arranged on all the bottom fixing stand columns respectively and are fixedly supported by the outer wrapping plate, and the closed cavity is filled with waste rock and soil materials. According to the guardrail, the protective capability and the sound insulation effect of highway construction are improved, and building construction and repeated recycling of materials are facilitated.
本发明公开了一种公路装配式固底临时护栏及建造方法，固底立柱沿公路方向等间距布置，各固底立柱的下端伸入到路基地面的柱孔内并分别通过多个抗拉销钉固定，抗拉销钉下端通过水泥浆固定在柱孔底部、上端与固底立柱可拆卸连接，固底立柱与柱孔之间的环空内填充废弃岩土材料；各固底立柱的上端伸出于路基地面的高度相等，外包覆板构成围合在各固底立柱外、沿公路方向延伸的封闭空腔，内部横隔板分别设置在各固底立柱上并与外包覆板支撑固定，封闭空腔内填充废弃岩土材料。这种护栏提高公路施工的防护能力、隔音效果，并便于建造施工及材料的重复循环使用。
