Prestress anchoring method applying negative Poisson's ratio structure grouting body
The invention discloses a prestress anchoring method applying a negative Poisson's ratio structure grouting body, and belongs to the technical field of slope supporting. The anchoring effect of the anchor rod is enhanced through grouting containing a novel material at the anchoring section of the anchor rod. According to the technical scheme, when the side slope is reinforced, a special-shaped anchor rod is placed in a drill hole penetrating through a sliding face, and then the space between the special-shaped anchor rod and the drill hole is filled with a grouting material formed by mixing a negative Poisson's ratio structural body and a grouting body; the negative Poisson's ratio structural body is of a three-dimensional solid structure and is in a cube shape, and the six surfaces of the cube are sunken towards the center of the cube. The supporting effect of the anchor rod in anchoring engineering can be enhanced by utilizing the mechanical property of the novel negative Poisson's ratio material, and the problems that a traditional anchor rod is poor in stability, insufficient in supporting resistance and complex in construction technology are solved.
本发明公开了一种运用负泊松比结构灌浆体的预应力锚固方法，属于边坡支护技术领域。在锚杆的锚固段通过含新型材料的灌浆来增强锚杆的锚固作用。本发明的技术方案为：加固边坡时，在穿过滑动面的钻孔中放入异型锚杆，然后在异型锚杆和钻孔之间填充负泊松比结构体与灌浆体混合而成的灌浆材料；所述负泊松比结构体为三维的实体结构，呈立方体状，并且立方体的六个表面均朝向立方体中心凹陷。本发明能够通过利用新型的负泊松比材料的力学性质，加强锚杆在锚固工程中的支护作用，规避了传统锚杆稳定性较差，支护阻力不足，施工工艺复杂的问题。
