Bridge prestressed pipeline slurry supplementing method
The invention relates to the technical field of bridge prestressed duct slurry supplementing, in particular to a bridge prestressed pipeline slurry supplementing method which comprises the following steps: S10, finding a longitudinal or transverse prestressed pipeline grouting non-compact area, and marking on a prestressed beam plate; S20, conducting windowing on the highest position and the lowest position of the non-dense grouting area marked on the prestressed beam plate; S30, inserting a slurry supplementing and feeding pipe into the prestressed pipeline through a window in the lower end,and inserting a slurry supplementing and discharging pipe into the prestressed pipeline through a window in the upper end; S40, respectively sealing the slurry supplementing inlet pipe and the slurrysupplementing outlet pipe with the prestressed pipeline; and S50, starting grouting from the slurry supplementing and feeding pipe until the concentration of the discharged slurry flowing out of the slurry supplementing and discharging pipe is consistent with the concentration of the fed slurry, and then stopping slurry supplementing. The method is effective and convenient, is a remedial measure when the grouting defect exists in the pipeline, can prolong the service life of the bridge and prolong the durability of the bridge, and guarantees the normal exertion of a bridge prestress system.
本发明涉及桥梁预应力孔道补浆技术领域，具体涉及一种桥梁预应力管道补浆方法，包括步骤：S10.找到纵向或横向预应力管道注浆不密实区，并在预应力梁板上进行标记；S20.对预应力梁板上标记的注浆不密实区的最高和最低位置进行开窗；S30.将补浆进浆管通过下端开窗口插入预应力管道内，将补浆出浆管通过上端开窗口插入预应力管道内；S40.将补浆进浆管和补浆出浆管分别于与预应力管道密封；S50.从补浆进浆管开始注浆，直至补浆出浆管流出的出浆浓度与进浆浓度一致，停止补浆。该方法有效、便捷，是对管道存在压浆缺陷时的一种补救措施，可以提高桥梁的使用寿命和耐久性，保障桥梁预应力体系的正常发挥。
