喷锚支护是喷射混凝土,喷射混凝土与锚杆,挂钢筋网喷射混凝土与锚杆等类型的支护或衬砌的总称。喷锚支护不是被动地承受岩土层的压力,而是主动加固、抑制岩土体的变形发展,充分利用其自稳能力和自支承作用,防止岩土体的松动和坍落与其紧密结合形成一体。喷锚支护具有机械化程度高、省工、省料、工期短,可以降低造价等优点。本文主要介绍喷锚支护工程作用原理、在边坡治理中的施工工艺、优点等。 Shotcrete anchor support is the general term for shotcrete, shotcrete and anchor, shotcrete and anchor for hanging steel mesh, and other types of support or lining. Spray and anchor support is not passive to withstand the pressure of rock and soil, but active reinforcement, inhibition of deformation of rock and soil development, and make full use of its self-stability and self-supporting role to prevent the loosening and collapse of rock and soil and its close integration Form one. Spray anchor support with a high degree of mechanization, labor, material saving, short construction period, can reduce the cost advantages. This article mainly introduces the principle of shotcrete and bolt support engineering, construction technology and advantages in slope treatment.
