摘要
在围岩节理、裂隙发育地质条件下,为保证隧道在多雨季节施工时的洞口围岩稳定及施工安全,通过应用大管棚加注水泥-水玻璃双液浆技术,达到了预期效果。结合工程实践,从浆液材料、配比、注浆压力、注浆量及注浆要点等方面,对大管棚加注水泥-水玻璃双液浆技术进行了总结,以期为同类工程施工提供借鉴。
In the geological conditions of surrounding rock joint and fracture development, in order to ensure the stability and con struction safety of suirounding rock at tunnel entrance in rainy season, the expected effect is achieved by the tech no logy of addi ng ceme nt-sodium silicate double-liquid slurry for large pipe shed. Combining with engineering practice, the technology of adding ceme nt-sodium silicate double-liquid slurry for large pipe shed is summarized from the aspects of slurry material, proportion, grouting pressure, grouting volume, key grouting points, and so on, so as to provide referenee for similar engineering construction.
