Method for preventing orifice soil body disturbance during soil nail construction
The invention discloses a method for preventing orifice soil body disturbance during soil nail construction. Comprising the following construction steps of slope excavation, small guide pipe construction, soil nail mechanical hole forming, soil nail steel bar insertion, soil nail grouting solidification, soil nail wall steel bar mesh hanging, electric welding connection of a small guide pipe steel bar mesh and a soil nail wall steel bar mesh, and concrete surface protection. The problems that when an existing soil nailing wall is constructed, mechanical hole forming vibration is large, impact is high, disturbance and collapse of a soil body near a soil nailing hole are likely to happen, and a large cavity is formed are solved. The disturbance and collapse phenomena of a soil body near a hole opening during mechanical hole forming are reduced, large-size holes are avoided, and the slope stability is improved; materials and time for repairing the holes are saved; and the slope surface is flat and attractive.
本发明公开了一种土钉施工时防止孔口土体扰动的方法。包括以下施工步骤：开挖坡面、施工小导管、土钉机械成孔、插入土钉钢筋、土钉注浆固化、挂土钉墙钢筋网、将小导管钢筋网与土钉墙钢筋网电焊连接、喷射混凝土护面。本发明解决了现有土钉墙施工时机械成孔振动大、冲击强，易发生土钉孔附近土体扰动、坍塌，形成较大空洞的问题。减少机械成孔时孔口附近土体的扰动、坍塌现象，避免出现较大体积的空洞，提高边坡稳定性；节约修补空洞的材料和时间；使坡面平整、美观。
