Directional grouting pipe pile
The invention discloses a directional grouting pipe pile. The directional grouting pipe pile specifically comprises a specially-made grouting plug and a pipe pile grouting hole. Wherein the grouting plug is of a hollow structure, and three grouting hole groups are formed in the grouting plug; each grouting hole group comprises at least four grouting holes, an annular polyurethane leaking stoppage belt is fixed outside the upper grouting hole group and the lower grouting hole group, the middle grouting hole group is aligned to the grouting holes of the pipe pile, and the outer diameter of the leaking stoppage belt is slightly smaller than the diameter of the inner wall of the pipe pile; the top of the grouting plug is connected with a geological drill rod, and the geological drill rod is communicated with a grouting pump on the ground for grouting; a grouting hole group is reserved in the pipe pile in the range of each meter, and a single stop-grouting plug is mounted in each grouting hole; a fixing frame is installed on the pile top and used for fixing a grouting plug and a geological drill rod. The leaking stoppage belt expands after being soaked by water flowing out of the grouting hole, the expanded leaking stoppage belt is filled in a hole between the inner wall of the pipe pile and the leaking stoppage belt, and the slurry leakage phenomenon of the curing agent can be prevented.
本发明专利公开了一种定向灌浆的管桩，具体包括：特制的灌浆塞和管桩灌浆孔。其中：所述灌浆塞为中空结构，灌浆塞中有三个灌浆孔组；所述灌浆孔组中，每组包含至少四个灌浆孔，其中上部灌浆孔组和下部灌浆孔组外面固定一条环形聚氨酯堵漏带，中部灌浆孔组对准管桩灌浆孔，所述堵漏带外径稍小于管桩内壁直径；所述灌浆塞顶部连接地质钻杆，地质钻杆连通至地面的灌浆泵进行灌浆；所述管桩在每米范围内预留了灌浆孔组，灌浆孔中安装了单项止浆塞；所述桩顶安装一个固定架，用于固定灌浆塞以及地质钻杆；所述堵漏带被灌浆孔流出的水浸湿后膨胀，膨胀后的堵漏带满管桩内壁和堵漏带之间的孔隙，能够防止固化剂漏浆现象。
