Prefabricated bridge pier connection construction method adopting first grouting
The invention belongs to the technical field of bridge prefabrication and assembly, and particularly relates to a pre-grouting prefabricated bridge pier connection construction method which specifically comprises the following steps: firstly, grouting materials are poured into a grouting sleeve of a prefabricated bridge pier, a grouting hole is blocked, and the grouting materials in the grouting sleeve are sealed by a grouting stopping pad; and meanwhile, the combined trough plate is placed on the bearing platform, and grouting materials are poured into the trough. And then the grouting sleeve of the prefabricated pier is in butt joint with the bearing platform overhanging steel bar, the redundant grouting material is extruded out of the grout discharging hole of the grouting sleeve, the grouting material in the combined trough plate can fill the splicing seam between the pier and the abutment, and the grouting material in the grouting sleeve is further prevented from flowing out. According to the grouting sleeve, the mode that grouting is conducted firstly, and then reinforcing steel bars are inserted is adopted, the grouting sleeve has the advantages of being good in grouting fluidity, compact in grouting and free of grout leakage, the problem that sleeve grouting is not full is solved, and the construction process is simple and easy to implement.
本发明属于桥梁预制拼装技术领域，尤其涉及一种先灌浆的预制桥墩连接施工方法，具体为：首先向预制桥墩的灌浆套筒内灌入灌浆料，封堵灌浆孔，依靠止浆垫封闭灌浆套筒内灌浆料。同时，将组合槽板放置于承台上，槽内倒入灌浆料。然后将预制桥墩的灌浆套筒与承台外伸钢筋对接，将多余灌浆料从灌浆套筒的排浆孔挤出，组合槽板内灌浆料可填充墩台之间拼接缝，进一步防止灌浆套筒内灌浆料流出。本发明的灌浆套筒采用先灌浆、后插钢筋的方式，具有灌浆流动性好、灌浆密实、不漏浆的特点，解决了套筒灌浆不饱满的问题，且施工过程简单、易行。
