What is Jet Grouting?

Jet-grouting is a process of creating “soil concrete columns” or jet-grouted columns in place with a stabilizing grout mix delivered under high pressure and flowing through nozzles at the end of a monitor inserted in a borehole. The soil concrete column is created by rotating and lifting the monitor at a precalculated slow, smooth, constant speed, cutting the soil with water and/or air while tremie-feeding an engineered grout slurry at high pressures through the base of the monitor to achieve thorough mixing and a consistent geometry and quality soilcrete columns.

The common uses for jet-grouting are to underpin the foundation, seal the bottom of the planned excavation, and provide support for the excavation.

Jet-grouting system can stabilize foundations, provide barriers, and gives excavation support.

Jet-grouting ground improvements find application for the following:

● Horizontal barriers

● Groundwater control

● Tunneling

● Support excavation

● Underpinning

What are the Advantages of Jet-Grouting?

One of the main advantages of jet-grouting is that it is less dependent on soil type than most other grouting methods. Because it physically mixes the soil with a stable fluid rather than permeating or displacing. It can be utilized in stabilizing most clays, bay mud, peat, silts, sand, and some grave soils.

Here are some other advantages of Jet-Grouting:

● Can be accomplished in limited spaces

● Provides unique design flexibility

● Can accomplish a high cement grout column without causing an enormous ground disturbance.

● Can stabilize soil foundations

● Provide Barriers

● Rapid installation

● Increase bearing capacity

Feature of XiTan Jet Grouting Drilling Rig:

1. This type of drilling rig is suitable for the construction of multi-pipe rotary jetting method with outer diameter of drill pipe 142;

2. It can show mud volume, air volume, ground pressure, rotation speed, lifting speed, lifting distance, step distance, swing angle, etc;

3. In order to prevent the drill pipe from falling into the hole, the upper and lower grippers are equipped. When the drill pipe is inverted, it is ensured that at least one of the upper and lower grippers can tighten the drill pipe. When the upper and lower grippers act together, it must be ensured that one of the two grippers tightens the drill pipe, and the other gripper or chuck can be opened;

4. Optional wireless transmission for monitoring and equipment control on the drilling rig, with a stable wireless transmission range of 200m to 300m;
