High-pressure jet grouting pile grouting pipe
The high-pressure jet grouting pile grouting pipe comprises a drill bit and a drill rod, the drill bit is fixedly installed at the bottom end of the drill rod, a high-pressure conveying pipe is arranged in the drill rod, a first high-pressure conveying pipe is arranged on one side of the inner wall of the drill rod, and at least one slurry discharging pipe is axially arranged in the high-pressure conveying pipe; an air inlet pipe is arranged at the top of the drill rod, a second high-pressure conveying pipe is arranged on the other side of the inner wall of the drill rod, a connector is arranged at the bottom of the drill rod, a first nozzle is connected to the bottom of the first high-pressure conveying pipe, a second nozzle is connected to the bottom of the second high-pressure conveying pipe, and a drill hole is formed below the drill bit. High-pressure gas is adopted to further pressurize sprayed slurry, fully extrude and cut surrounding soil, it is ensured that the slurry and the surrounding soil are fully and evenly mixed, high-pressure jet grouting is conducted on the interior of a drill hole from top to bottom through multiple sets of nozzles, cement is saved, the reinforcing effect is good, and the construction cost is greatly reduced.
本发明提供了一种高压旋喷桩注浆管，包括钻头与钻杆，所述钻头固定安装在所述钻杆底端部，所述钻杆的内部设置有高压输送管，钻杆内壁的一侧设置有第一高压输送管，所述高压输送管内轴向设置有至少一个排浆管；所述钻杆顶部制有进气管，钻杆内壁的另一侧设置有第二高压输送管，钻杆的底部设置有接头，第一高压输送管的底部连接有第一喷嘴，第二高压输送管的底部连接有第二喷嘴，钻头的下方设置有钻孔；本发明采用高压气体对喷浆进一步加压，充分挤压、切割周边土体，确保浆液与周边土体充分均匀混合，利用多组喷嘴对钻孔内部进行由上到下的高压喷射灌浆，节约水泥，加固效果好，且大大降低施工成本。
