High fill roadbed construction technology and construction device thereof
The invention belongs to the technical field of roadbed filling, and particularly relates to a high-fill roadbed construction technology and a high-fill roadbed construction device. A trimming unit is hinged to the end of a large arm of the excavator body. The finishing unit comprises a cross beam; a trimming pressing plate is arranged at one end of the bottom face of the cross beam, and an arc-shaped triangular cutter is arranged on the side, close to the excavator body, of the bottom of the trimming pressing plate. The excavator body moves to the slope of the embankment, a large arm of the excavator body drives the trimming unit to move to the position to be trimmed, the large arm of the excavator body presses the arc-shaped triangular cutter downwards to cut the arc-shaped triangular cutter into the slope of the embankment, the excavator body horizontally moves along the embankment and drives the arc-shaped triangular cutter to horizontally move, and the overfilled width of the two sides of the embankment is cut off. Not only is the construction efficiency of the high-fill roadbed improved, but also the probability of excessive excavation and less excavation in the width of overfilling of the two sides of the roadbed is reduced.
本发明属于路基填筑技术领域，具体的说是一种高填方路基施工工艺及其施工装置，包括挖掘机主体；所述挖掘机主体的大臂端部铰接有修整单元；所述修整单元包括横梁；所述横梁的底面一端设置有修整压板，所述修整压板的底部靠近挖掘机主体的一侧为弧形三角切刀；挖掘机主体移动至路堤的边坡处，挖掘机主体的大臂驱动修整单元移动到待修整处，挖掘机主体的大臂将弧形三角切刀下压切入路堤的边坡处，挖掘机主体沿着路堤水平移动，带动弧形三角切刀水平移动，将路基两侧超填的宽度予以切除，不但提高了高填方路基的施工效率，而且降低了路基两侧超填的宽度多挖和少挖的概率。
