The invention relates to the technical field of bridge maintenance, and especially relates to a municipal bridge repairing construction method. The method comprises the following steps: S1, breaking broken concrete in an expansion joint transition area; S2, fully moistening the groove wall of a preformed groove through water; S3, fixing reinforcing steel bar rings to the bottom of the preformed groove; S4, placing an expansion joint body in the preformed groove, and staggering the anchor rings of the expansion joint body and the reinforcing steel bar rings; S5, putting in transverse steel bars, and connecting the transverse steel bars to the anchor rings and the reinforcing steel bar rings at the same time; S6, pouring steel fiber reinforced concrete into the preformed groove, and performing vibrating and plastering to form a steel fiber reinforced concrete layer; S7, laying geotextile on the steel fiber concrete layer, and performing watering maintenance for 2-3 h; and S8, removing the geotextile, paving asphalt concrete above the steel fiber concrete layer, and rolling to form an asphalt concrete surface layer. According to the bridge repairing method, the situation that the repairing material is loosened and peeled off from the preformed groove too early can be reduced, and the effect of improving the durability of the bridge repairing structure is achieved.
本申请涉及桥梁养护技术领域，尤其是涉及一种市政桥梁修复施工方法，其包括以下步骤：S1、破除伸缩缝过渡区破损的混凝土；S2、用水对预留槽的槽壁充分润透；S3、在预留槽的底部固定加固钢筋环；S4、将伸缩缝主体放置于预留槽内，使伸缩缝主体的锚环与加固钢筋环相交错；S5、放入横向钢筋，并使横向钢筋同时连接于锚环和加固钢筋环；S6、向预留槽内浇筑钢纤维混凝土，振捣、抹面，形成钢纤维砼层；S7、在钢纤维砼层上方铺设土工布，洒水养护2‑3h；S8、除开土工布，在钢纤维砼层上方摊铺沥青混凝土，碾压形成沥青砼面层。该桥梁修复方向可减少修复材料过早从预留槽内松散剥落的情况，起到提升桥梁修复结构耐久性能的效果。
