High embankment slope stabilizing structure and construction method thereof
The invention discloses a high embankment slope stabilizing structure. The high embankment slope stabilizing structure comprises a retaining wall, steel pipe piles and anchor rods; the retaining wallis arranged at the foot of a high embankment slope, concrete-filled steel pipe piles are arranged on the inner surface of the retaining wall, an excavation step and a gravel drainage zone are arrangedat a filling and excavation interface, the bottoms of the concrete-filled steel pipe piles and the steel pipe piles penetrate through the gravel drainage zone, and the upper sections of the steel tube piles are sleeved with grouting sleeves correspondingly; the lower end of the grouting sleeves extend to the gravel drainage zone, the upper end of each grouting sleeve is connected with a groutingopening through a grouting pipe, a fixed pulley and a pipeline channel are arranged inside each concrete-filled steel pipe pile, the anchor rods are is fixed in a rock stratum behind the excavation step, the exposed parts of the tops of the anchor rods are connected with steel strands, and the steel strands are connected to the fixed pulleys or the steel pipe piles at the same height; the steel strands connected to the fixed pulleys are led out of crown beam through the pipeline channel and connected with a steel strand tensioning device. The high embankment slope stabilizing structure is suitable for reinforcing and active control of embankment deformation in the embankment construction and operation process, and is particularly suitable for embankment projects with high requirements forembankment stability and later operation safety.
本发明公开了一种高路堤边坡稳定结构，包括：挡土墙、钢管桩和锚杆；高路堤坡脚处设置挡土墙，所述挡土墙内表面设置钢管混凝土桩，填挖交界面处设置开挖台阶及碎石排水带，所述钢管混凝土桩和钢管桩的底部穿过碎石排水带，钢管桩的上段套有注浆套管，注浆套管下端至碎石排水带，上端通过注浆管连接注浆口，所述钢管混凝土桩内部设置定滑轮及管线通道，所述锚杆固定在开挖台阶后的岩层中，顶部外露部分连接钢绞线，钢绞线连接在等高处的定滑轮或钢管桩上，连接在定滑轮上的钢绞线通过管线通道引出冠梁，连接钢绞线张拉装置。适用于路堤施工及运营过程中路堤变形的加固及主动控制，尤其是对路堤稳定及后期运营安全要求较高的路堤工程特别适用。
