Construction method of high abrupt slope reinforced embankment
The invention relates to the technical field of embankment construction, in particular to a construction method of a high abrupt slope reinforced embankment, which comprises the following steps: filling a permeable filler with a certain thickness above a roadbed to form a permeable cushion layer, and arranging at least one first geocell layer formed by filling a PET (Polyethylene Terephthalate) high-strength geocell through the permeable filler on the permeable cushion layer; a gravel protection layer is constructed above the first geocell layer, and the gravel protection layer is rolled and flattened; a plurality of reversely-wrapped geogrid layers are constructed on the gravel protection layer layer by layer, and the reversely-wrapped geogrid layer on the lower layer is fixedly connected with the reversely-wrapped geogrid layer on the upper layer; and after construction of all the reverse-wrapping geogrid layers is completed, a buffer filler layer is constructed on the top of each reverse-wrapping geogrid layer, and a pavement structure layer is constructed on each reverse-wrapping geogrid layer after the buffer filler layers are compacted and flattened. The method has the advantages that reinforcing construction of the embankment with the slope ratio of 1: 0.75-1: 1 and the slope ratio slower than 1: 1 can be achieved, and the formed reinforced embankment structure has better stability and is also suitable for greening arrangement.
本发明涉及路堤施工技术领域，尤其是一种高陡坡加筋路堤的施工方法，在路基的上方填筑一定厚度的透水性填料形成透水垫层，并在所述透水垫层上设置至少一个由PET高强土工格室通过透水性填料填筑而成的第一土工格室层；在所述第一土工格室层的上方施作砾石保护层，并对所述砾石保护层进行碾压平整；在所述砾石保护层上逐层施作多层反包土工格栅层，并使下层的反包土工格栅层与上层的反包土工格栅层固定连接；在各所述反包土工格栅层施工完成后，在其顶部施作缓冲填料层，待缓冲填料层压实平整后在其上方施作路面结构层。本发明的优点是：可实现对坡率为1:0.75‑1:1和坡率缓于1:1的路堤加筋施工，所形成的加筋路堤结构具有更好的稳固性，也适于绿化的布置。
