Column-free bearing platform type rock anchor rod foundation structure for power transmission line and method
The invention discloses a stand-column-free bearing platform type rock anchor rod foundation structure and method for a power transmission line. Anchoring steel pipes are arranged in rock anchor rod holes in a penetrating mode, and a plurality of anchoring foundation bolts are fastened through stirrups for the foundation bolts and anchor discs; the anchoring threaded rod structure is freely arranged in the anchoring steel pipe in a penetrating and nesting mode, the stress form of the anchoring steel pipe is full-length bonding with an external anchoring agent, the stress form of the anchoring threaded rod is a bottom pressure form, and the anchoring steel pipe and the anchoring threaded rod are connected through concrete pouring to form the stand-column-free bearing platform. By means of the column-free bearing platform type rock anchor rod foundation structure, the pulling resistance of the anchor bars can be improved, the mechanical anchoring performance of the anchor bars can be enhanced, the requirement for the anchoring length of foundation bolts in concrete is lowered, and the construction efficiency is improved. The requirement for the anchoring length in concrete can be met only through the bearing platform without a stand column.
本发明公开了一种输电线路用无立柱承台式岩石锚杆基础结构及方法，利用锚固钢管穿设于岩石锚杆孔内，多个锚固地脚螺栓通过地脚螺栓用箍筋和锚盘紧固，多个锚固地脚螺栓与锚固钢管、锚固螺纹杆上端通过混凝土浇筑形成无立柱承台，本申请采用锚固螺纹杆结构自由穿设和嵌套于锚固钢管内，锚固钢管的受力形态为与外部锚固剂的全长粘结，锚固螺纹杆的受力形态为底部压力型，提高了锚筋的综合抗拔承载能力，减少了施工质量对锚筋承载力的不利影响，本发明提供的无立柱承台式岩石锚杆基础结构能够提高锚筋的抗拔能力，增强其机械锚固性能，降低地脚螺栓在混凝土里的锚固长度要求，达到无需设置立柱仅仅依靠承台即可满足在混凝土里的锚固长度要求。
