Bridge expansion joint transition area repairing construction method
The invention discloses a repairing construction method for a bridge expansion joint transition area. The repairing construction method comprises the following steps that S1, raw materials in a reserved groove in the expansion joint transition area are removed; s2, the surface of the main beam in the reserved groove in the transition area is subjected to roughening treatment, and an interface agent is sprayed after cleaning; s3, #-shaped anchoring ribs are arranged in the expansion joint transition area reserved grooves, and then a concrete composite material is poured; s4, natural curing; the adopted repairing material has the characteristics of high strength and high toughness, is good in crack resistance and impact resistance, is high in bonding strength with a pavement material and expansion joint profile steel, can simultaneously meet the requirements of later strength, elasticity and toughness, impact resistance, elasticity modulus and the like on the premise of meeting excellent early strength and early hardening performance, and is suitable for large-scale popularization and application. And meanwhile, the matching property of new and old materials is good, secondary damage such as cracking and breakage easily occurring again in a short time is avoided, and the comprehensive mechanical properties such as fracture toughness and impact resistance of a repaired structure can be remarkably improved and excellent durability can be obtained by combining the bonding agent for use.
本发明公开了一种桥梁伸缩缝过渡区修复施工方法，包括以下步骤：S1,清除伸缩缝过渡区预留槽中的原材料；S2,将过渡区预留槽内主梁表面进行粗糙处理，清理之后喷洒界面剂；S3,在伸缩缝过渡区预留槽内设置井字型锚固筋，然后浇注混凝土复合材料；S4,自然养护；所采用的修补材料具有高强度高韧性特征，抗裂抗冲击性能好，同时与路面材料及伸缩缝型钢粘接强度高，在满足具备优异的早期强度和早期硬化性能的前提下，能够同时满足后期强度、弹韧性、抗冲击、弹性模量等诸多性能要求，同时新旧材料的匹配性好，避免短时间内易再次出现开裂、破损等二次破坏，将其结合界面剂的使用，能显著提高修复结构的断裂韧性、抗冲击性等综合力学性能以及取得优异的耐久性能。
