港口工程混凝土建筑物,由于种种原因,常常出现一些宽窄不同深度不一的裂缝,影响了结构的正常使用寿命,从而需要补强以恢复其整体性。研究环氧树脂灌浆,国内外已有20多年的历史,但由于环氧树脂的憎水性和粘度较大,故灌入性差,在缝内有水的情况下,粘结强度低。环氧树脂灌浆后的粘结缝耐久性问题,尚少见研究。针对上述问题,我所自1977年开展了潮湿裂缝,饱水裂缝的灌浆补强研究,并对有压力水作用下裂缝灌 Due to various reasons, port engineering concrete structures often have cracks with different depths and widths, affecting the normal service life of structures and thus requiring reinforcement to restore their integrity. Study of epoxy grouting, at home and abroad for more than 20 years of history, but due to epoxy resin hydrophobic and viscosity larger, so poor penetration, in the case of water in the seam, the bond strength is low. Epoxy resin grouting bond seam durability problems, are still rare. In response to the above problems, I have carried out since 1977, wet cracks, filled with water-filled fracture reinforcement studies, and under pressure of water under the action of crack irrigation
