Vibration immersed tube grouting structure and grouting method
The invention relates to the field of civil construction equipment, in particular to a vibration immersed tube grouting structure and a grouting method, the structure comprises a pile body and a pile tip, the pile tip is provided with a grouting cavity, the side wall of the pile tip is provided with a grouting hole communicated to the grouting cavity, the grouting structure further comprises a slurry guide rod slidably arranged in the grouting hole, and the slurry guide rod is arranged in the grouting hole. An outer cover covering the grouting hole is arranged at one end of the grout guide rod, a limiting block is arranged at the other end of the grout guide rod, and the limiting block is in sliding fit with the grouting hole, so that when the pressure of the side, away from the grout guide rod, of the limiting block is larger than a set value, the limiting block pushes the grout guide rod to move towards the outer side of the pile tip, and the grouting hole is formed in the pile tip. The invention further provides a grouting method. By arranging the telescopic slurry guide rod, the stability and balance of secondary grouting can be improved, and the problems existing in the prior art are effectively solved.
本发明土建施工设备领域，尤其是一种振动沉管注浆结构及注浆方法，结构包括桩身和桩尖，所述桩尖设有注浆腔，所述桩尖的侧壁设有连通至所述注浆腔的注浆孔，所述注浆结构还包括可滑动设置在所述注浆孔的导浆杆，所述导浆杆的一端设有覆盖所述注浆孔的外盖、另一端设有限位块，所述限位块与所述注浆孔滑动配合，以使得所述限位块背离所述导浆杆一侧压力大于设定值时，所述限位块推动所述导浆杆向所述桩尖外侧移动，本发明还提供了一种注浆方法。本发明通过设置了能够伸缩的导浆杆，可以提高二次注浆的稳定性和均衡性，有效的解决了现有技术中存在的问题。
