Prestressed anchor rod composite soil nail reinforced slope structure and construction method thereof
The invention discloses a prestressed anchor rod composite soil nail reinforced side slope structure and a construction method thereof.The prestressed anchor rod composite soil nail reinforced side slope structure comprises metal grid panels evenly distributed along the side slope face, a metal net layer is arranged on the side face close to the metal grid panels and the side slope face, and the metal net layer comprises a plurality of sets of metal net single bodies; the metal net single bodies are evenly distributed in the longitudinal direction of the slope face of the slope and used for enhancing the stability of the slope face of the slope. The vertically downward first construction hole is formed in the position, close to the slope surface, of the top of the slope in an extrusion hole forming mode, the multiple sets of grouting pipes are embedded into the first construction hole, two times of grouting are conducted, the longitudinal shear resistance of the slope is enhanced through first-time grouting, and after second-time grouting is conducted, the longitudinal shear resistance of the slope is improved. And mortar penetrates through the overflow holes to overflow and uniformly covers the surface of the slope surface, so that the metal net layer is conveniently positioned and mounted, and the stability of the slope surface is enhanced.
本发明公开了一种预应力锚杆复合土钉加固边坡结构及其施工方法，包括沿边坡坡面均匀分布的金属网格面板，靠近金属网格面板与边坡坡面的一侧面上设有金属网层，金属网层包括若干组金属网单体，金属网单体沿着边坡坡面的纵向上均匀分布，用于增强边坡坡面的稳定性；本发明通过在边坡的顶部且靠近边坡坡面位置上经挤压成孔的方式形成垂直向下的第一施工孔，并向着第一施工孔内埋设有若干组灌浆管，经过两次注浆，通过第一次注浆，不仅仅增强了边坡的纵向抗剪能力，而且第二次注浆后，使砂浆穿过溢出孔溢出，并均匀覆盖在边坡坡面表面，方便金属网层定位安装，增强边坡坡面的稳定性。
