Grouting device for post-grouting construction of pile foundation
The grouting device comprises a grouting pipe and a grouting valve arranged at the bottom of the grouting pipe, the grouting valve comprises an outer sleeve fixedly arranged at the bottom of the grouting pipe, an upper limiting sealing plate and a lower limiting sealing plate are correspondingly and fixedly arranged at the upper end and the lower end of the outer sleeve respectively, and a first slurry discharging hole is formed in the position, close to the middle, of the side wall of the outer sleeve; the inner sleeve is sleeved with the outer sleeve in the mode that the inner sleeve can be driven to slide in the length direction of the outer sleeve, and the inner sleeve can be correspondingly limited by the upper limiting sealing plate and the lower limiting sealing plate after sliding upwards and downwards; the elastic piece is arranged in the outer sleeve and used for driving the inner sleeve to abut against the upper limiting sealing plate; the valve element is fixedly arranged on the lower limiting sealing plate, extends upwards and then penetrates through the top of the inner sleeve upwards; by means of the grouting device, backflow of cement paste in a pile hole can be effectively blocked; meanwhile, the risk that a valve port of the valve body structure cannot be opened can be reduced, and the grouting quality is guaranteed; meanwhile, the structure can be simplified, and the manufacturing cost is reduced.
本发明公开了一种桩基后注浆施工用注浆装置，包括注浆管和设置于注浆管底部的注浆阀，注浆阀包括：固设于注浆管底部的外套管，外套管上下两端分别对应的固设有上限位封板和下限位封板，外套管侧壁靠中部位置设有第一排浆孔；内套管，内套管以可被驱动沿外套管长度方向滑动的方式内套于外套管，且内套管向上和向下滑动后可分别对应的被上限位封板和下限位封板限位；弹性件，内置于外套管并用于驱使内套管抵接至上限位封板；阀芯，固设于下限位封板并向上延伸后向上贯穿内套管顶部；运用该注浆装置能够有效阻断桩孔内水泥浆的回流；同时能够减少阀体结构阀口打不开的风险，保证注浆质量；同时能够利于简化结构，减少制作成本。
