Stay cable micro pile retaining wall structure and construction method
The invention provides a stay cable micro pile retaining wall structure and a construction method. The stay cable micro pile retaining wall structure comprises a plurality of micro piles, and the top ends of the micro piles are fixedly connected with prestressed grouting anchor cables; the micro piles are arranged in at least two rows, and the two rows of micro piles are arranged in a staggered mode. An arc-shaped retaining wall is arranged between every two adjacent micro piles of the row of micro piles close to the top of the slope, and the protruding direction of each arc-shaped retaining wall faces the top of the slope. And a force transmission wall is arranged between the rear row of micro piles and the adjacent front row of micro piles. In a preferable scheme, the diameter of each micro pile is less than 1 meter. By adopting the structure that the array micro piles are matched with the prestressed grouting anchor cables, the anti-sliding effect of the side slope is greatly improved. The structure that the arc-shaped retaining wall is matched with the force transmission wall is arranged, lateral pressure can be evenly transmitted to the multiple rows of micro piles, and the effect of resisting rockfall and landslide impact is greatly improved.
本发明提供一种斜拉索微型桩挡墙结构及施工方法，包括多根微型桩，微型桩的顶部端头与预应力注浆锚索固定连接；所述的微型桩成至少两排布置，两排微型桩之间交错布置；在靠近边坡顶部的一排微型桩的相邻微型桩之间设有弧形挡墙，弧形挡墙凸起方向朝向边坡的顶部；在后一排微型桩与相邻的前一排微型桩之间设有传力墙。优选的方案中，所述的微型桩直径低于1米。通过采用阵列微型桩配合预应力注浆锚索的结构，大幅提高边坡的抗滑效果。设置的弧形挡墙配合传力墙的结构，能够将侧向压力均匀的传递给多排的微型桩，大幅提高抗落石和滑坡冲击的效果。
