Grouting for foundation settlement is a common method used to address foundation issues, suitable for dealing with problems like foundation settlement and uneven soil. The principle of grouting reinforcement is to inject a bonding agent into the foundation to enhance the cohesion between soil particles, forming an integrated structure. This increases the bearing capacity of the foundation and reduces settlement.

Specific operational steps are as follows:

1. Drilling: Use a drilling machine to bore holes in the foundation, and determine the depth and size of the holes according to the requirements of the grouting process.

2. Buried Grouting Pipe: The grouting pipe is buried in the hole, including an outlet end extending into the ground and a pipe at the other end, which can be used to connect other equipment.

3. Sealing Holes: Seal the holes with cement mortar to prevent the slurry from leaking out.

4. Trial Grouting: Perform a trial grouting before the actual grouting to determine the grouting pressure, flow rate, and other parameters, ensuring the equipment operates normally.

5. Formal Grouting: Injects slurry into the foundation, achieving thorough reinforcement through multiple grouting cycles.

6. Sealing: After grouting is complete, remove the grouting tube and seal the holes to prevent the grout from leaking or oozing out.

Be mindful to select appropriate foundation materials and adhesives when performing ground sinking grouting. Determine suitable parameters and equipment based on the foundation conditions and the requirements of the grouting process. Additionally, closely monitor the equipment operation during the grouting process to ensure safe construction.
