Bridge bent cap reinforcing process
The invention discloses a bridge cover beam reinforcement process. The process comprises the following steps: S10, preparation of newly reinforced concrete: weighing the following raw materials: cement, fly ash, gravel, sand, water, a water reducing agent, an expanding agent, cellulose fibers and steel fibers; s20, on-site reinforcement, specifically comprising the following steps: S21) erecting a supporting bracket; (S22) chiseling is conducted; (S23) steel bars are planted; (S24) a bottom die bracket is erected; (S25) a formwork is installed; (S26) pouring is conducted; and S27) mold removal and maintenance. According to the invention, the shrinkage compensation performance, the crack resistance and the like of the material, especially the mutual coordination with the homogeneity, and the design is optimized, so that the durability and the mechanical property of the reinforced concrete are improved and the homogeneity of the reinforced concrete is ensured; and a complete set of construction processes of on-site scabbling, bar planting, pouring and curing are combined, so that the cohesiveness, integrity and crack resistance of the reinforced concrete and the original concrete are ensured, and the reinforced concrete and the original concrete are cooperatively stressed, so that an excellent reinforcing effect is achieved.
本发明公开了一种桥梁盖梁加固工艺，包括如下步骤：S10、新加固混凝土的制备步骤：称取如下原料：水泥、粉煤灰、碎石、砂、水、减水剂、膨胀剂、纤维素纤维、钢纤维；S20、现场加固步骤，具体包括以下步骤：S21)搭设支撑托架；S22)凿毛；S23)植筋；S24)搭设底模托架；S25)安装模板；S26)浇筑；S27)拆模养生。本发明从材料补偿收缩性能、抗裂等性能、尤其是与匀质性之间相互协调，优化设计进而各性能协同发挥提高加固混凝土的耐久性和力学性能，保证这种加固混凝土的均匀性；再结合现场凿毛、植筋、浇筑、养护成套施工工艺，保证加固混凝土与原有混凝土的黏结性、整体性、抗裂性，进而协同受力，达到优异的加固效果。
