摘　　要：结合香港某深海沉箱隧道病害治理,介绍了化学灌浆技术对细微裂缝进行粘结补强修复的施工技术,指出采用低黏度液态化学灌浆材料治理地下工程混凝土病害,能收到粘结强度高、损伤小、防腐、防渗、耐老化、成本低的效果。Combining with disease treatment of a Hong Kong deep sea caisson tunnel, the article introduces construction technology for bond reinforcement repairing of minute cracks using chemical grouting, and points out that applying low viscosity liquid chemical grouting material for underground concrete disease treatment can achieve high bond strength, little damage, anticorrosion, impermeable, aging resistance and low cost effect.
