Railway slope prefabricated and assembled post-poured framework slope protection structure and construction method thereof
The invention discloses a railway slope prefabricated and assembled post-poured framework slope protection structure which comprises a plurality of slope protection units, inspection ladder steps, concrete foot guards and post-poured concrete core columns. The slope protection units extend longitudinally and vertically on a railway slope in a repeated combination mode; each slope protection unit is formed by assembling a main framework and a branch framework and used for defining the pouring range of the post-poured concrete core columns on the slope surface; the inspection ladder steps are arranged on the side surfaces of the slope protection units; the concrete foot guards are arranged at the lower parts of the slope protection units; the post-poured concrete core columns fill external gaps between the slope protection units. Precast cement boards are adopted, the weight of each precast cement board is small, people can conveniently carry and assemble the precast cement boards, the bottoms of the precast cement boards are effectively fixed through steel drill rods and concrete cushion blocks, and the tops of the precast cement boards are fixed through fixing clamping grooves. Compared with a traditional steel formwork, the using number of concrete formworks of the framework protection structure is reduced to 0, the formwork disassembling process is omitted, and construction is more efficient.
本发明公开了一种铁路边坡阈值拼装后浇式骨架护坡结构，包括：多个护坡单元、检查梯踏步、混凝土护脚和后浇混凝土芯柱，多个护坡单元以重复组合的形式在铁路边坡纵向和竖向延伸；每个护坡单元由主骨架和支骨架拼装组成，用于在坡面上限定出后浇混凝土芯柱的浇筑范围；所述检查梯踏步设置在护坡单元侧面；所述混凝土护脚设置在护坡单元的下部；所述后浇混凝土芯柱填充在多个所述护坡单元之间的外部空隙。采用预制水泥板，预制水泥板的单块重量小，方便人员搬运组装，预制水泥板的底部通过钢钎和混凝土垫块有效固定底部，板顶通过固定卡槽固定，与传统的钢模板相比，本发明的骨架防护结构的混凝土模板用量降至为0，省去模板拆卸工序，施工更高效。
