一、概 述用压送设备将一定材料配成的浆液，灌入地层或缝隙内，使其扩散、胶凝或固化，以达到增加岩体强度或降低渗透性的施工过程，称为注浆施工方法或注浆法。注浆法最早用于建筑工程中，距今已有170多年的历史，目前，国内外已广泛应用到井巷、隧道、水利、水电等工程中，成为在复杂地质条件下，处理垮塌、漏水、滑坡等问题的技术方法之一，对加固破碎围岩，提高坑道稳定性具有其它方法难已达到的效果。注浆材料在岩体中硬化后，改善了岩体原有的机械物理性能，使其颗粒粘结更牢固，更密实，抗压强度、内聚力、内摩擦角等相应改善，稳定性得到提高。尤其是系统注浆后，在坑道周围形成一定范围的 First, an overview With a pressure delivery equipment will be dubbed a slurry of material, poured into the formation or gap, so that its proliferation, gelling or curing, in order to achieve the increase of rock mass strength or reduce the permeability of the construction process, known as the grouting construction Method or grouting method. Grouting method was first used in construction projects, dating back more than 170 years of history, at present, both at home and abroad have been widely used in engineering, tunnels, water conservancy, hydropower and other projects, as complex geological conditions, handling collapse, leaking , Landslide and other issues one of the technical methods, to strengthen the broken rock, increase the stability of the tunnel has other methods have been difficult to achieve the effect. After the grouting material hardens in the rock mass, the original mechanical and physical properties of the rock mass are improved, and the particle bonding is firmer and denser. The compressive strength, cohesion and internal friction angle are correspondingly improved and the stability is improved. Especially after grouting the system, a certain range is formed around the tunnel
