Cast-in-place box girder bridge floor transverse prestress multi-duct intelligent mud jacking system and method
The invention relates to a cast-in-place box girder bridge floor transverse prestress multi-duct intelligent mud jacking system and method. The method comprises the following steps that water and electricity are supplied to the system; switch ball valves are mounted on a mud jacking inlet and a mud jacking outlet at two ends of the prestressed duct; the mud jacking branch pipeline is connected with a switch ball valve on the mud jacking inlet; cleaning the prestressed duct; a grouting material is hoisted to a bridge floor and conveyed to a high-speed stirring barrel through a grouting material feeding screw pump; pulping by a high-speed stirring barrel and a low-speed stirring barrel; the mud jacking screw pump is used for jacking mud to the mud jacking pipeline, and the mud is pressed into the prestressed duct through the mud jacking branch pipeline; and the grouting pipeline is dismantled, and next circulation grouting is carried out. Compared with a traditional treatment method, the method has the advantages of being economical, feasible, intelligent, safe, efficient, energy-saving, cost-reducing, environment-friendly and the like, and can effectively solve the key technical problems that a bridge floor transverse prestressed pipeline is small in cross section area, the grouting work efficiency is low, the slurry fluidity is easily reduced, grouting is difficult to be full, and the slurry quality is uncontrollable.
本发明是一种现浇箱梁桥面横向预应力多孔道智能压浆系统及方法，包括以下步骤：系统通水通电；预应力孔道两端的压浆进口和压浆出口上安装开关球阀；压浆支管路与压浆进口上的开关球阀连接；清洗预应力孔道；压浆材料吊运至桥面，并通过压浆料上料螺杆泵输送至高速搅拌筒；高速搅拌筒和低速搅拌筒制浆；压浆螺杆泵压浆至压浆管路，并通过压浆支管路压至预应力孔道内；拆除压浆管路并进行下一个循环压浆。本发明较传统处理方法具有经济可行、少人化、智能化、安全高效、节能降本、绿色环保等优势，能够有效解决桥面横向预应力管道横断面面积小，压浆工效低，易造成浆液流动度降低，压浆难以饱满，浆液质量不可控等关键技术问题。
