锚杆框架梁是近年来广泛用于高速公路路堑边坡防护的一种防护形式,适用于边坡高度较大,稳定性较差的土质边坡和岩石路堑边坡。锚杆框架梁的施工工艺流程比较复杂,主要施工流程为:边坡开挖→钻孔、安装锚杆并锚固→绑扎框架梁钢筋→安装模板→浇筑框架梁混凝土→养生。通过对以往工程的经验总结,认为边坡坡面作为框架梁的载体,对锚杆框架梁的施工和质量控制有着至关重要的作用。
The anchor frame beam is a kind of protection widely used in the protection of expressway cutting slope in recent years. It is suitable for soil slope and rock cut slope with high slope stability and poor stability. The construction process of the bolt frame beam is rather complicated. The main construction flow is: excavation of the slope → drilling, installation of anchor rod and anchoring → binding of frame beam reinforcement → installation of template → pouring of frame beam concrete → health preservation. Based on the experience of previous projects, it is considered that slope slope is the carrier of frame beam, which plays an important role in the construction and quality control of the beam.
