摘要
针对复杂水文地质条件下地下工程施工期间面临的基坑渗漏问题,通过分析注聚氨酯、注双液浆及注单液浆等各技术特点,研究制定了先用聚氨酯堵水、再用双液浆加固、最后用单液浆充填的综合堵漏施工方案,有效解决了基坑渗漏问题。单、双液注浆混合封堵为类似条件下的工程施工和应急救援提供了案例参与和技术指导。
Aiming at the analysis of the technical characteristics of polyurethane injection, double liquid slurry injection and single liquid slurry injection, a comprehensive leakage stoppage construction scheme was developed, which uses polyurethane first to block water, then uses double liquid slurry to reinforce, and finally uses single liquid slurry to fill, effectively solving the leakage problem of foundation pit. It provides technical guidance and engineering cases for engineering construction and emergency rescue under similar conditions.
