Construction process of lime nail composite tension-compression anti-floating anchor rods for layered rock soil
The invention discloses a construction process of lime nail composite tension-compression anti-floating anchor rods for layered rock soil. The construction process comprises the steps of arranging tension-compression anti-floating anchor rods and arranging lime nails, wherein each tension-compression anti-floating anchor rod comprises compression anchor bars, tension anchor bars, anchor bar pipes and a bearing plate, the compression anchor bars are connected with the bearing plate, the anchor bar pipes are arranged on the outer sides of the compression anchor bars in a sleeving mode, and the tension anchor bars are connected with the bearing plate which is installed at the bottom of one corresponding anchor rod hole; and the lime nails comprise lime filling sections and clay filling sections, the lime nails are installed in lime nail holes, the bottom sections of the lime nails are the lime filling sections, and the top sections of the lime nails are the clay filling sections. According to the construction process, the pulling force is evenly distributed on the anchoring length by means of the tension-compression anti-floating anchor rods, the anchoring force of the unit length of each tension-compression anti-floating anchor rod does not change along with the depth through coordinated deformation of the lime nails and a foundation, and the foundation bearing capacity, the pulling resistance of the anchor rods and the permeability of the rock soil are all improved through the coordinated effect of the lime nails and the tension-compression anti-floating anchor rods.
本发明公开一种用于分层岩土的石灰钉复合拉压抗浮锚杆施工工艺。本发明包括设置拉压抗浮锚杆和石灰钉，拉压抗浮锚杆包括压锚筋、拉锚筋、锚筋管以及承载板；所述压锚筋与承载板连接，锚筋管套设于压锚筋外侧；拉锚筋与承载板连接，承载板安装于锚杆孔底部；所述石灰钉包括石灰填充段与粘土填充段；所述石灰钉安装于石灰钉孔中，石灰钉底段设置为石灰填充段，石灰钉顶段设置粘土填充段。本发明中拉压抗浮锚杆使得拉拔力均匀的分布在锚固长度上，石灰钉与地基的协调变形，使得拉压抗浮锚杆单位长度的锚固力不随深度发生改变，石灰钉与拉压抗浮锚杆的协调作用，使得地基承载力、锚杆的抗拔力、岩土的渗透性均改善。
