十、用化学补强方法加固桥梁用高分子化学材料(环氧树脂类、甲凝材料等)灌浆修补裂缝,或以环氧树脂粘贴补强层(玻璃布、钢板、钢筋)加固桥梁承重构件是一种国内外常用且经实践证明行之有效的桥梁加固方法。兹分述如下: (一)用高分子化学材料修补裂缝与水泥灌浆相比,由于环氧树脂浆液硬化后的强度较高,通过压力进入裂缝周围受损或疏松的混凝土内,使其恢复整体性,达到恢复
X. Reinforcement of Bridge Reinforced Bridges with Chemical Modifications (Epoxy Resins, A-Cohesive Materials, etc.) Grout cracks are to be repaired by chemical strengthening methods or reinforcement layers (glass cloths, steel plates, reinforcing bars) are reinforced with epoxy resin Is a commonly used and proven practice at home and abroad bridge reinforcement method. Here are the points are as follows: (a) with polymer chemical material repair cracks compared with the cement grout, due to the higher strength of the epoxy grout hardened, through the pressure into the crack around the damaged or loose concrete, to restore the whole Sex, to restore
