Root anchor rod reinforced structure in highway embankment widening project and construction method
The invention discloses a root system anchor rod reinforced structure in highway embankment widening engineering and a construction method, the root system anchor rod reinforced structure comprises a new embankment and an old embankment, a plurality of groups of reinforced layers are distributed in the new embankment from top to bottom, and each group of reinforced layer comprises two gravel filling layers and a geogrid sandwiched between the gravel filling layers; root anchor rods are arranged at the positions of the reinforcement layers, the root anchor rods are perpendicular to the slope face of the old embankment and anchored in the old embankment, and the geogrid is connected with the root anchor rods. The root anchor rod of a specific structure is anchored at the step position of the reconstructed and extended old embankment, the anchor rod is connected with the geogrid, cooperative deformation of the old embankment, the novel root anchor rod and the geogrid is achieved, and the overall stability of the embankment is improved.
本发明公开了一种高速公路路堤拓宽工程中的根系锚杆加筋结构及施工方法，根系锚杆加筋结构包括新路堤和老路堤，新路堤内部从上至下分布有多组加筋层，每组所述加筋层包括两层碎石填充层和夹在中间的土工格栅；所述加筋层的位置设有根系锚杆，根系锚杆垂直老路堤的坡面锚固于老路堤内部，土工格栅与根系锚杆连接。本发明在改扩建老路堤台阶处锚固特定结构的根系锚杆，锚杆与土工格栅相连接，实现老路堤‑新型根系锚杆‑土工格栅协同变形，提升了路堤整体稳定性。
