Soft rock high slope anchor rod supporting system and method
The invention discloses a soft rock high slope anchor rod supporting system and method. The system comprises an anchoring hole, an end expansion hole, an anchor rod, a core cage and an anchoring part. Anchoring holes and end expanding holes are formed by drilling holes in designated points of the soft rock high slope, and the core cage can follow up in time to support the holes in the hole forming process; the anchor rod is clamped and fixed in the core cage, the front end of the anchor rod is provided with a tip cone head and a knurling section steel bar which are located in the end expansion hole, and the rod core connected with the tip cone head is pulled to enable the knurling section steel bar to be of a ball flower-shaped structure; the anchoring part is formed by grouting the anchoring hole and the end expanding hole and comprises the rod body anchoring part and the expanding head anchoring part, the contact area between the anchoring part and the surrounding soil body is increased, a supporting system and the soil body are combined more firmly, the anti-drawing performance of the anchor rod and the reinforcing effect on rock soil are enhanced, meanwhile, the rod body located in the soil body is closed, and therefore the supporting system is protected. Water and soil erosion is avoided, and it is guaranteed that the slope protection time is longer.
本发明公开了一种软岩高边坡锚杆支护系统及方法，该系统包括锚固孔、端部扩大孔、锚杆、芯笼及锚固部。通过在软岩高边坡上指定点打孔形成锚固孔和端部扩大孔，芯笼可在成孔过程中及时跟进对孔洞进行支撑；锚杆卡接固定在芯笼内，其前端设有顶锥头和压花段钢条，两者位于端部扩大孔内，拉动与顶锥头连接的杆芯，使压花段钢条呈球花状结构；锚固部通过对锚固孔、端部扩大孔注浆后形成，包括杆身锚固部和扩大头锚固部，其增加了与周围土体的接触面积，使支护系统与土体结合更加牢靠，增强锚杆的抗拉拔性能和对岩土的加固作用，同时将位于土体内的杆体封闭，避免了水土侵蚀，保证护坡时间更长。
