Automatic Crouting Lubrication System

Automatic Grouting Lubrication System

The grouting system mainly consists of grouting pump, mixing barrel, fermentation box, pipeline and connecting parts, solenoid valve and electrical control system. By injecting anti friction lubricating material (bentonite or polymer material) between the pipe and the soil, efficiently reduce the friction force between the pipe and soil, thereby reducing the pushing force at the rear end of the pipeline, improving the reliability and efficiency of the main jacking system, avoiding pipe damage, and effectively reducing risks. It is an important and essential process in pipe jacking construction.

According to different geological conditions and jacking lengths, the number of grouting systems, grouting points, and automatic control of grouting volume can be selected to achieve the best grouting friction reduction effect.
