Auxiliary grouting device for vertical prestressed pipeline
The invention discloses an auxiliary grouting device for a vertical prestressed pipeline, which is arranged on the outer side of a finish rolling twisted steel in a sleeving mode and comprises a grouting pipe, the grouting pipe is arranged on the outer side of the finish rolling twisted steel in a sleeving mode, and an interval space is formed between the grouting pipe and the finish rolling twisted steel. A steel cushion top plate and a steel cushion bottom plate are welded to the top and the bottom of the grouting pipe respectively, the finish rolling twisted steel penetrates through the steel cushion top plate and the steel cushion bottom plate respectively, and the top of the steel cushion top plate and the bottom of the steel cushion bottom plate are screwed through finish rolling nuts respectively. A top grouting nozzle and a bottom grouting nozzle which are communicated with the interval space are formed in the position, close to the top and the position close to the bottom, of one side of the grouting pipe in a protruding and extending mode respectively, and the top grouting nozzle and the bottom grouting nozzle are connected with an exhaust hose and a grouting hose in a sealed mode respectively. The problem of blockage caused by grout is solved, and meanwhile the follow-up grouting process is very smooth.
本申请公开了一种竖向预应力管道压浆辅助装置，套设于精轧螺纹钢筋外侧，包括一压浆管，所述压浆管套设于所述精轧螺纹钢筋外侧，所述压浆管与所述精轧螺纹钢筋之间形成有间隔空间，所述压浆管顶部与底部分别焊接有钢垫顶板与钢垫底板，所述精轧螺纹钢筋分别穿过所述钢垫顶板与钢垫底板，所述钢垫顶板的顶部与所述钢垫底板的底部分别通过精轧螺母拧紧，所述压浆管一侧靠近顶部处与靠近底部处分别凸伸形成有连通所述间隔空间的顶部压浆嘴与底部压浆嘴，所述顶部压浆嘴与底部压浆嘴分别密封连接有排气软管和压浆软管。本发明解决了浆液造成堵塞的问题，同时后续压浆过程十分顺利。
