XCMG Pipe Jacking Machine Helps Hunan Water Conservancy Project

With the XCMG XDN1800-R pipe jacking machine, the cutterhead precisely reached the designated location in the receiving well, successfully completing the pipe jacking section of a single water conservancy project in Hunan Province. This marks a crucial step toward the project’s goal of water supply.
The project, with a total length of 1,147 meters and a single jacking distance of 540 meters, represents a long-distance, large-diameter pipe jacking project. The project’s underground pipelines are complex, and the construction process required overcoming technical challenges such as groundwater infiltration and unstable rock formations.
The XCMG XDN1800-R pipe jacking machine’s heavy-duty cutters, made of high-hardness alloy and featuring a high-torque power output system, can precisely adapt to diverse geological conditions. During construction, the machine achieved an average daily advance of 15 meters, a 20% increase compared to traditional methods.
Faced with the complex construction environment, XCMG dispatched professionals to conduct on-site inspections and discuss solutions with the construction company. To address the challenges of abundant groundwater and the difficulty of cutter changes, the XCMG team optimized the cutter’s cutting trajectory, improving cutting efficiency and service life. They also optimized sealing features, ensuring the smooth progress of the project. “The XCMG pipe jacking machine is not only reliable but also highly efficient. I’m very satisfied!” The XCMG team promptly responded to customer needs and provided comprehensive support and assurance for the equipment’s stable operation.

The XCMG XDN1800-R rock pipe jacking machine once traversed Provincial Highway 202, supporting my country’s first inter-prefecture-level city nuclear power heating long-distance pipeline project. This contribution to XCMG’s efforts has opened a new chapter in the long-distance, cross-regional, and large-scale development of nuclear power heating on the Jiaodong Peninsula.
