Efficient construction method for rapidly repairing cement concrete bridge floor by using UHPC (Ultra High Performance Concrete)
The invention relates to an efficient construction method for quickly repairing a cement concrete bridge floor by using UHPC, which belongs to the technical field of bridge repairing and comprises the following steps: step 1, damage assessment: judging the damage condition according to the damage range and depth of the bridge floor; step 2, surface treatment: dedusting and decontaminating the damaged surface, and cleaning a boundary crack area which is not communicated with the center of the damaged area by using a tool, so that the boundary crack area is communicated with the center of the damaged area to form a complete repair surface; 3, recording a damaged range and depth data after cleaning; 4, preparing a UHPC material, and preparing and manufacturing raw materials according to the data recorded in the step 3; 5, the prepared UHPC material is poured into the center of a damaged area, and a boundary crack area needs to be guided by a thin rod; 6, after repairing is completed, the damaged area is covered with a thin film for wet curing, and the method can improve the construction efficiency, relieve traffic pressure, shorten the repairing period and reduce the repairing cost.
本发明涉及一种采用UHPC快速修复水泥混凝土桥面高效施工方法，属于桥梁修补技术领域，包括步骤一：损坏评估，根据桥面损坏范围、深度判断损坏情况；步骤二：表面处理，对损坏表面除尘、去污以及利用工具将不与损坏区域中心连通的边界裂缝区域清理，使得边界裂缝区域与损坏区域中心连通，形成完整的修补面；步骤三：清理后的损坏范围以及深度数据记录；步骤四：UHPC材料制备，根据步骤三记录的数据进行原材料的准备以及制作；步骤五：将制备好的UHPC材料倾倒在损坏区域中心，边界裂缝区需要细棒引导；步骤六：修补完成后，对损坏区域覆盖薄膜进行湿养护，本发明能够提高施工效率，缓解交通压力，缩短修补周期，降低维修成本。
