Reinforcing and repairing method for damaged concrete surface layer
The invention discloses a reinforcing and repairing method for concrete surface layer damage, which comprises the following steps: step 1, determining a concrete surface layer damage area, and chiseling away damaged concrete to a fresh concrete base surface; 2, concrete chippings are cleared away, and anchoring steel bars are arranged in an array mode according to the chiseling area; step 3, thoroughly cleaning and drying the fresh concrete base surface, paving lower-layer epoxy mortar after drying, and fully compacting the lower-layer epoxy mortar; 4, a steel wire mesh flush with the upper surface of the lower-layer epoxy mortar is fixed to the array anchoring steel bars; and 5, upper-layer epoxy mortar is laid on the steel wire mesh, and the upper-layer epoxy mortar is compacted and trowelled to the designed repairing thickness. The anchoring steel bars are additionally arranged on the concrete foundation surface, the steel wire mesh is additionally arranged on the top of the concrete foundation surface, and the bonding strength between interfaces is improved in the mode that the anchoring steel bars and the steel wire mesh are fully compacted and wrapped when epoxy mortar is laid, so that the epoxy mortar and concrete form a whole, and the construction quality is guaranteed; and the service time of the epoxy mortar repairing surface layer is further prolonged.
本发明公开的用于混凝土面层破损的加固修复方法，包括：步骤1、确定混凝土面层破损区域，将破损混凝土凿除至新鲜混凝土基面；步骤2、清理混凝土碎屑，根据凿除面积大小阵列布置锚固钢筋；步骤3、彻底清洗新鲜混凝土基面并烘干，干燥后铺筑下层环氧砂浆并充分压实；步骤4、在阵列锚固钢筋上固定与下层环氧砂浆上表面平齐的钢丝网；步骤5、在钢丝网上方铺筑上层环氧砂浆并压实抹平至设计修复厚度。本发明通过在混凝土基础面上增设锚固钢筋及其顶部增设钢丝网，铺筑环氧砂浆时充分压实包裹住锚固钢筋与钢丝网的方式提高界面之间粘接强度，使环氧砂浆与混凝土形成一个整体，保证了施工质量，进一步提升了环氧砂浆修复面层的服役时间。
