一、喷锚网主护技术概述 (一)喷锚网支护技术的作用原理 喷锚网支护是利用锚杆、钢筋网、喷射混凝土的共同作用对边坡进行支护。施工时,在边坡开挖后立即喷射混凝土,然后打锚杆,铺设钢筋网,将锚杆端部与钢筋网连成一体。因喷射混凝土、钢筋网、砂浆锚杆的联合支护作用,提高了土体的强度,增强了土体的稳定性,并可防雨水冲刷。 (二)喷锚网支护技术的形成和发展 喷锚网支护源于工程建设中的一项应用技术——锚固与注浆。锚固技术和注浆技术虽然是两项不同的技术,但就工程建设而言,又是相互密不可分
I. Overview of Main Technique of Spray Anchor Network (A) The principle of spray anchor net support technology The spray anchor net support is to support the slope by the joint action of anchor rod, reinforced mesh and shotcrete. During construction, the concrete is sprayed immediately after the excavation of the slope, and then the anchor rod is used to lay a reinforcement mesh, and the end of the anchor rod is integrated with the reinforcement mesh. The combined support of sprayed concrete, reinforced mesh, and mortar anchors increases the strength of the soil, enhances the stability of the soil, and protects against rainwater. (B) the formation and development of spray anchor network support technology Spray anchor network support from the construction of an engineering technology - anchorage and grouting. Although anchoring technology and grouting technology are two different technologies, they are inseparable from each other in terms of engineering construction.
