Support method adopting steel pipe pile grouting combined with waist beams and anchor rods
The invention relates to the technical field of support engineering, in particular to a support method adopting steel pipe pile grouting combined with waist beams and anchor rods. According to the method, the foundation pit support adopts a steel pipe pile plus waist beam plus self-drilling anchor rod support form; steel pipe piles and pile top contact beams are firstly constructed before a foundation pit is excavated, a vertical soft soil layer is made to form a whole, the self-drilling anchor rods are then implemented in the excavation process, anchorages of the self-drilling anchor rods aredirectly fixed to the waist beam structure, the anchor rods and the waist beams jointly bear the load of the reinforcement structure, and the anchor rods are connected through the waist beams, so that the anchoring force of the anchor rods is transmitted to a slope body, the stress state of the slope body is changed, the self-stability capability of the slope body is improved, the phi-8 steel barmesh piece plus C 20 concrete is hung on the slope surface for closing, and drainage holes are formed in the slope surface in the quincunx form at the intervals of 2-3 m. The soil retaining structurewith large thickness and good rigidity is formed, a traditional row pile and continuous wall soil retaining structure is replaced, and the process is relatively simple.
本发明涉及一种的支护工程技术领域，具体来说，是一种钢管桩注浆结合腰梁锚杆支护方法。基坑支护采用钢管桩+腰梁+自钻式锚杆支护形式；在基坑开挖前先施工钢管桩及桩顶联系梁，使坚向软弱土层构成一个整体，然后在开挖过程中实施自钻式锚杆，自钻式锚杆的锚碇直接固定于腰梁结构上，使锚杆和腰梁共同承担加固结构物荷载，通过腰梁将锚杆连接，从而将锚杆的锚固力传递给坡体，改变坡体应力状态，提高坡体自稳能力，坡面挂设Φ8钢筋网片+C20砼进行封闭，坡面2‑3m梅花形布置泄水孔。形成了厚度较大、刚度较好的挡土结构，代替了传统的排桩、连续墙挡土结构，工艺相对简单。
