Pipe Jacking Construction

Pipe jacking construction is a core non-excavation technology widely used in urban infrastructure projects such as water supply and drainage pipelines, gas pipelines, and communication cable laying. It features minimal impact on ground traffic, buildings, and the surrounding environment, making it an indispensable construction method in modern urban construction. However, during the pipe jacking process, the drilling fluid (mud) plays a key role in lubricating the pipe wall, stabilizing the borehole, and carrying slag. The quality of mud treatment directly affects construction efficiency, project safety, and environmental protection compliance.

As a professional solids control equipment manufacturer, we provide reliable and customized mud treatment solutions specifically designed for pipe jacking projects. Our systems are engineered to separate solids from slurry efficiently, allowing the treated slurry to be reused in the excavation process. This not only reduces water consumption and disposal costs but also improves construction stability and overall project efficiency.

During pipe jacking operations, a jacking machine or micro-tunneling machine advances through the soil from a launch shaft to a reception shaft, while prefabricated pipes are pushed forward simultaneously. The excavation process generates a large volume of slurry mixed with soil particles such as sand, silt, and clay. If this slurry is not properly treated, it may lead to equipment wear, reduced jacking efficiency, unstable excavation conditions, and environmental pollution. Therefore, an efficient solids control and slurry treatment system plays a critical role in ensuring smooth and continuous pipe jacking construction.

In a typical pipe jacking slurry circulation system, the excavated slurry is pumped from the cutting head to the surface, where it passes through multiple stages of solids control equipment. The treated slurry is then stored, adjusted if necessary, and returned back to the jacking machine. Each stage of separation ensures optimal slurry performance and protects downstream equipment from excessive wear.
