Construction method of grouting flower tube anchor rods in support process of soft soil slope
The invention discloses a construction method of grouting flower tube anchor rods in the support process of a soft soil slope. Through a structure that flower tube anchor rods of the grouting flower tube anchor rods are combined with an anchor reinforcement, the anchor reinforcement is fixed in the flower tube anchor rods by adopting an anchor rod fixing bracket and a flower tube fixing bracket; secondary grouting is performed through double grouting holes to ensure the grip of a cement column after mud is solidified; and the strength of slope soil is strengthened, through secondary anchor spraying, a common system is formed by the anchor reinforcement, a concrete spraying layer and the slope, slope loosening and separation are prevented and controlled, the slope is stabilized, expandablesteel sheets at the tail ends of the flower tube anchor rods ensure large area contact with reinforcement meshes and the concrete spraying layer, a structural surface and a level are reinforced, the integrity and the self-supporting capacity of the slope are more effectively improved, and the development of deformation is inhibited. The method is strong in feasibility, low in cost, and high in safety and stability, the effect of uplift in soft soil area is significant, a great influence of soil properties is effectively solved, effective uplift resistance is provided for soft soil slopes, andthe construction method is suitable for promotion and application.
本发明公开了一种注浆花管锚杆在软土边坡支护中的施工方法，通过注浆花管锚杆的花管锚杆与锚杆钢筋结合结构，采用锚杆固定支架和花管固定支架，将锚杆钢筋固定于花管锚杆中，通过双注浆孔进行二次注浆保证泥浆固化后的水泥柱的抓力；强化边坡土体强度；通过二次喷锚，使锚杆钢筋、混凝土喷层和边坡形成共同作用的体系，防治边坡松动、分离，稳定边坡，花管锚杆末端可扩式钢片保证与钢筋网片和混凝土喷层大面积接触，加固结构面和层面，更有效地提高边坡的整体性和自承能力，抑制变形的发展。该方法可行性强、成本低，安全稳定性较好，且软土区域抗拔的效果显著，有效解决了受土体性质影响较大，为软土边坡提供有效的抗拔力，宜于推广应用。
