土钉墙支护是通过土钉技术的加固使其成为一个复合挡土结构。使用专用设备将混凝土高速喷向土层表面,有的采用干料,在喷射口处加入适量的水。当混凝土在土层表面凝固硬化后,形成一个整体,防止雨水冲刷土层表面。从而防止土层坍塌。 Soil nailing wall support is reinforced by soil nailing technology to make it a composite retaining structure. Special equipment is used to spray the concrete at high speed onto the surface of the soil, and some use dry materials, adding the appropriate amount of water at the injection port. When the concrete is solidified and hardened on the surface of the soil, a whole body is formed to prevent the rain from flushing the surface of the soil. In order to prevent the collapse of the soil.
