Grouting slurry for soft rock tunnel and grouting method
The invention discloses grouting slurry for a soft rock tunnel and a grouting method. Existing grouting slurry for soft rock tunnel construction is single-liquid cement mortar and is difficult to quickly condense to form certain strength, and the deformation control effect on a soft rock stratum is poor. The double-liquid grouting slurry comprises a liquid A and a liquid B, and the liquid A and the liquid B are mixed and stirred to form the double-liquid grouting slurry; the liquid A is prepared from the following materials: cement, fly ash, bentonite, sand, lime and water; and the material of the liquid B comprises water glass. The peripheral gap of the tunnel is filled with the double-liquid slurry, and the slurry has high condensation speed and can form an effective closed ring. By filling gaps around the tunnel, the soft rock stratum can be reinforced, the strength of the stratum is improved, and tunnel deformation is reduced; and the construction process is simple, and can be widely applied to soft rock stratum tunnel construction and similar tunnel engineering with poor geological environment.
本发明公开了一种用于软岩隧道的注浆浆液及注浆方法。现有用于软岩隧道建设的注浆浆液为单液水泥砂浆，难以快速凝结形成一定强度，对于软岩地层的变形控制效果不佳。本发明包括A液和B液，并由A液和B液混合搅拌形成双液注浆浆液；所述A液的材料包括：水泥、粉煤灰、膨润土、砂、白灰、水；所述B液的材料包括水玻璃。使用双液浆液填充隧道周边间隙，浆液具有较快的凝结速度，能形成有效封闭圈。本发明通过填充隧道周边间隙，可对软岩地层加固，增加地层的强度，减小隧道变形；施工工艺简单，可广泛适用于软岩地层隧道施工及类似的地质环境不佳的隧道工程。
