Jet grouting drilling rig, also known as high-pressure jet grouting drilling rig, is a “scalpel” in the field of foundation treatment. It sprays cement slurry at a speed of 200-300km/h through the nozzle at the bottom of the drill pipe, cuts and stirs the surrounding soil, and forms a reinforced pile with a diameter of 0.5-3 meters. As an industry benchmark, the YG series drilling rig adopts a full hydraulic drive + intelligent control panel, with a jet pressure of up to 45MPa and a drilling depth of 10-60 meters, which can easily cope with complex geology such as soft soil, gravel, and rock formations. Compared with traditional technology, a jet grouting drilling rig does not need to excavate a large amount of earthwork, and the construction speed is increased by 3-5 times.

5 Advantages of using high pressure jet grouting drilling rig
- Efficiency: In a high-rise pile foundation project in the Philippines, the traditional method takes 45 days, and the YG drilling rig completes all 300 piles in 12 days, shortening the construction period by 73%.
- Cost killer: The case of Myanmar Expressway shows that the material cost is reduced by 42% (reducing the amount of steel bars used) and the fuel consumption is reduced by 35%.
- Excellent quality: The pile body strength reaches 8-12MPa in 28 days, the permeability coefficient is <1×10⁻⁶cm/s, and the anti-seepage effect far exceeds the industry standard.
- All-round warrior: It can use the “single-tube method” to deal with soft soil and the “three-tube method” to conquer hard rock. The depth of high slope rock anchoring exceeds 50 meters.
- Environmental protection pioneer: construction noise <75 decibels, mud discharge reduced by 90%, in line with global environmental regulations.
Grouting rig working principle
Drilling stage → Drill rod penetrates the designated stratum → High-pressure pump starts → Precise ratio of water, gas, and slurry → High-speed nozzle jet → cutting and mixing soil → forming a columnar reinforcement body. YG’s technological breakthroughs are:
- Intelligent frequency conversion system: Automatically adjusts the jet pressure according to the geology to avoid energy waste.
- Patented nozzle design: Streamlined structure reduces the pipe blockage rate by 85% and increases the service life by 2 times.
- Three-dimensional positioning system: Ensure that the verticality error of the pile body is <1%, suitable for super high-rise buildings.
Real testimonials from global customers
- Metro Extension in Manila, Philippines
“The thickness of the silt layer is 28 meters, while other equipment can only advance 8 meters per day. The daily advance of the YG drilling rig exceeds 22 meters! The operator monitors the pressure parameters in real time through the touch screen, and the pile uniformity is tested to be 98%.” - Slope reinforcement of Guatemala Hydropower Station
“70-degree steep slope anchoring is extremely difficult. The YG high slope rock anchoring machine uses directional jetting technology. The pull-out force of the anchor rod reaches 650kN, and it has experienced zero displacement after three heavy rain tests!” - New Town Development in Yangon, Myanmar
“The construction risk in the underground cave area is high. The YG high-pressure jet grouting drilling rig is very high. rig) forms a “cement plug” by filling the cave, and the foundation bearing capacity jumps from 80kPa to 320kPa. “
