AI Technical Summary
Existing mixing equipment results in poor dispersibility of admixtures when mixing admixtures and cement powder, which easily leads to agglomeration and poor slurry uniformity and fluidity. This is especially true when the amount of admixture added is small, making it impossible to mix thoroughly.
An interventional grouting dry material premixing device is adopted, including a small material batching machine, a mixing device, an adjustable screw conveyor, a stirring device, and a control system. The feeding accuracy is monitored by a weighing sensor, the premixing unit performs initial mixing, the mixing device combines high-speed and low-speed mixing, and the material viscosity detection device adjusts the mixing parameters in real time to ensure uniform mixing.
This method achieves uniform mixing of admixtures and cement powder, avoids slurry clumping, and improves construction efficiency and slurry quality.
