Umbrella type side slope anchor rod structure, side slope protection structure and anchoring method
The invention discloses an umbrella type side slope anchor rod structure, a side slope protection structure and an anchoring method. The umbrella type side slope anchor rod structure comprises an anchor rod, and a guide cap is arranged at the end of the inner side of the anchor rod; one or more umbrella-shaped assemblies are arranged on the anchor rod, and the umbrella-shaped assemblies are arranged at intervals in the length direction of the anchor rod; a plurality of grouting supporting pipes are arranged in the umbrella-shaped assembly. After the anchor rod structure is arranged in an anchoring drill hole, the umbrella-shaped assembly is tensioned outwards, and part of the grouting supporting pipe is inserted into a soil layer on the peripheral side of the anchoring drill hole, so that a primary anchoring body is formed. In the subsequent grouting operation, mortar is poured into the anchoring drill hole; when the anchoring drill hole is drilled, grouting is conducted from the large-size opening of the grouting supporting pipe, the grouting flows out from the small-size opening, then the grouting penetrates into a soil layer on the peripheral side of the anchoring drill hole to form a whole with the soil body, and finally a tree-root-shaped structure is formed in the soil body. And the inherent capability of the anchoring body is fully exerted, the self-stabilization capability of the soil body can be enhanced, the structure and the soil body are tightly connected together, and the construction safety and long-term stability of the slope protection engineering are ensured.
本发明公开了伞式边坡锚杆结构、边坡防护结构及锚固方法，包括锚杆，在锚杆的内侧端头设有导向帽；在锚杆上设有一个或多个伞形组件，伞形组件沿锚杆的长度方向间隔布设；伞形组件内设多根注浆支撑管。在锚杆结构置于锚固钻孔内后，通过向外张拉将伞形组件，将注浆支撑管的部份插入至锚固钻孔周侧的土层内，形成初步的锚固体。在后续的注浆操作中，砂浆灌入锚固钻孔内；由注浆支撑管的大尺寸开口处灌入，并从小尺寸开口处流出，随后渗透进锚固钻孔周侧的土层内，与土体形成一个整体，最后在土体内构成树根状结构；充分发挥锚固体自身固有的能力，能加强土体的自稳能力，把结构物和土体紧紧的联系在一起，确保了边坡防护工程的施工安全和长期稳定。
