Vertical prestressed pipeline mud jacking device and mud jacking method thereof
The invention discloses a vertical prestressed pipeline grouting device and a grouting method thereof, belongs to the technical field of bridge construction, and solves the problem that the top of a pipeline is insufficiently grouted due to incomplete exhaust of the top of the pipeline. According to the device, a mud jacking duct and an air outlet pipeline are arranged on an upper anchor bearing plate, one end of the mud jacking duct is opened in the side wall of a center hole of the upper anchor bearing plate and is close to the bottom face of the upper anchor bearing plate, and a mud inlet of the mud jacking duct can be externally connected with a mud inlet pipe of mud jacking equipment; an opening in one end of the air outlet pipeline communicates with a center hole of the upper anchorbearing plate, the connecting position is higher than that of the grouting pipeline and the upper anchor bearing plate, and air in the pipeline can be exhausted; the bottom of the upper anchor backingplate can be fixedly connected with a mud jacking pipe pre-buried in the prefabricated body and communicates with an external mud jacking pipe through a center hole of the upper anchor backing plate.Exhaust and grouting compaction of a top pipeline of the grouting pipe are facilitated, the defect that the top of the vertical prestress grouting pipe is not compact can be well overcome, construction is easy, and the construction period can be shortened.
本发明公开了一种竖向预应力管道压浆装置及其压浆方法，属于桥梁施工技术领域，解决了管道顶部排气不完全而导致管道顶部注浆不够密实。其技术方案要点是：其包括上锚垫板上开设有压浆孔道和出气管道，压浆孔道一端开口于上锚垫板的中心孔侧壁上且靠近上锚垫板的底面设置，压浆孔道的进浆口能够外接压浆设备的进浆管；出气管道一端开口连通上锚垫板的中心孔，且其连接位置高于压浆管道与上锚垫板的连接位置，能够将管道内空气排出；上锚垫板的底部能够与预埋在预制体内的压浆管固定连接，通过其中心孔连通外接压浆管。本发明利于压浆管的顶部管道排气以及压浆密实，能够较好的解决竖向预应力压浆管顶部不密实的缺陷，施工简单，能够缩短工期。
