Deep foundation pit grouting construction device
The invention provides a deep foundation pit grouting construction device which comprises a grouting pipe, a piston barrel is arranged in the grouting pipe in the axial direction in a sliding mode, the bottom end of the grouting pipe is closed, and grouting hole sets and anchoring mechanism sets are alternately arranged on the outer side of the lower section of the grouting pipe. The grouting hole set is provided with grouting holes formed in the side wall of the grouting pipe in a circumferential array mode, and the anchoring mechanism set is provided with anchoring mechanisms arranged on the inner side of the grouting pipe in a circumferential array mode. According to the grouting device, the anchoring plate and the sliding barrel are elastically supported, so that the anchoring plate is kept in the sliding barrel and the grouting pipe, the influence on the smoothness of the outer side of the grouting pipe is small, and no hindrance is caused when the grouting pipe is inserted into a drill hole.
本发明提供一种深基坑注浆施工装置，包括注浆管，所述注浆管的内部沿其轴向滑动设置有活塞筒，所述注浆管的底端封闭，所述注浆管的下段外侧交替设置有注浆孔组及锚固机构组，所述注浆孔组具有呈圆周阵列开设在所述注浆管侧壁上的注浆孔，所述锚固机构组具有呈圆周阵列在所述注浆管内侧的锚固机构；本发明中，锚固板与滑筒之间弹性支撑，使得锚固板保持在滑筒及注浆管的内部，对注浆管外侧的光滑度影响较小，在向钻孔内部插入注浆管时不会造成阻碍。
