High-pressure jet grouting pile applied to roadbed widening
The invention belongs to the technical field of road and bridge construction equipment, and particularly relates to a high-pressure jet grouting pile applied to roadbed widening, which comprises a drill bit, a slurry conveying pipe is arranged in the middle of the interior of the drill bit, a water conveying pipe is arranged in the middle of the slurry conveying pipe, and a plurality of drill blades are slidably arranged on the inner wall of the drill bit. A plurality of driving boxes are fixedly connected to the interior of the drill bit, a spray head is arranged on one side of each driving box, the spray heads are fixedly connected to the interior of the drill bit, a plurality of through holes are formed in the ends, close to the driving boxes, of the spray heads, and one end of each spray head is in sliding sealing connection with a moving pipe; a plurality of corrugated pipes are arranged between the moving pipe and the driving box, and by arranging a baffle and a stirring rod, when the spray head is not used, one end of the spray head can be sealed to prevent the phenomenon that in the working process of the high-pressure jet grouting pile, a large amount of impurities and soil enter the spray head, and consequently the spray head is blocked.
本发明属于路桥施工设备技术领域，具体的说是一种应用于路基拓宽的高压旋喷桩，包括钻头，所述钻头的内部中部设置有输浆管，所述输浆管的中部设置有输水管，所述钻头的内壁滑动设置有若干个钻叶，所述钻头的内部固定连接有若干个驱动箱，每个所述驱动箱的一侧均设置有喷头，所述喷头固定连接在钻头的内部，所述喷头靠近驱动箱的一端开设有多个通孔，所述喷头的一端滑动密封连接有移动管，所述移动管和驱动箱之间设置有若干个波纹管，通过设置有挡板和搅拌杆，可以在喷头不使用时，对喷头的一端进行密封来防止高压旋喷桩在工作过程中，其喷头的内部进入大量的杂质和泥土导致喷头发生堵塞。
