摘要: 混凝土质量是影响预应力锚索(杆)框架结构的关键因素,它直接影响着边坡加固的效果,高边坡框架现浇混凝土施工受现场条件限制,存在离析、振捣不到位、跑浆、胀模、劳动力成本偏高等问题,干法喷射混凝土可有效解决以上难题。本文结合甘肃小厂坝矿山环境恢复治理工程(二期)预应力锚杆框架施工的成功经验,对干法喷射混凝土施工的施工工艺及技术要点进行了介绍。

Abstract: Concrete quality is the key factor to affect the frame structure of pre-stressed anchor cable ( bar) and also direct-ly affects the slope reinforcement effect.High slope frame cast-in-place concrete is restricted by field conditions with segre-gation, uncompleted vibration tamping, slurry leakage, template swell and high labor cost, all the above can be effectively solved by dry spraying concrete.Combined with the successful experience in the pre-stressed anchor frame construction in Xiaochangba mine environmental restoration project ( the second phase) of Gansu Province, this paper introduces the tech-nical points of the dry spraying concrete construction technology.
