What are the Models of Single Pipe Jet Grouting Pile Equipment?
The leading equipment used in the single-pipe jet grouting method is a high-pressure grouting pump, jet grouting rig, grouting pipe, slurry pipe, and so on.
1. High-pressure grouting pump is the key equipment, through its high pressure to make the slurry cutting soil, to achieve the required injection range, forming a certain diameter of the pile. At present, the special high voltage frequency conversion grouting pump, foundation strengthening pump, and double liquid high voltage frequency conversion grouting pump produced by Shaanxi Xitan Geological Equipment Co., Ltd. are mainly used. The models are ZJB/BP, XTB, and so on.
2. Rotary jet drilling rig is the main role of the grouting pipe ( bottom with nozzle ) to the design depth to meet the design requirements of the lifting and rotating grouting pipe. At present, the drilling rig produced by Shaanxi Xitan Geological Equipment Co., Ltd. is mostly used, which has been improved to some extent. The models include XL-50, SRJP-145, GM-6A, GL-6000S, XPS-15, XL-3, RJP-65B, etc.
3. The slurry pipe is an inner diameter Φ21 rubber steel wire hose or inner diameter Φ21 steel pipe, that can withstand the pressure of 45 MPa or more. Its main function is to connect the high-pressure pump and rotary jet drilling rig, conveying slurry.
4. Grouting pipe is generally used Φ42 or Φ50 drill pipe, the bottom with a special nozzle, nozzle diameter is generally 2.0mm-3.0mm, the actual use of 2.3mm-2.5mm.
