The number of pipeline jacking projects in Hubei has increased, and MPP power pipelines are suitable for various types of municipal infrastructure

Hubei crossing pipe jacking project demand continues to rise

In recent years, the pace of urban renewal and municipal infrastructure construction in Hubei has been accelerating. Projects such as power grid upgrade in the old city, pipeline entry into the ground in the new area, and power expansion in the business district have been concentrated. The traditional excavation pipeline laying is easy to cause traffic congestion and road damage, and the application proportion of trenchless pipe jacking technology has continued to increase. Since 2024, the province's road jacking projects have increased by more than 40% year-on-year, mainly concentrated in the main and secondary arterial roads, residential areas, and transportation hubs around the power pipeline laying scene.

Core requirements of MPP power pipeline fitting pipe jacking construction

Pipe jacking construction requires high ring stiffness, tensile resistance, and wear resistance of pipes. MPP power pipelines use modified polypropylene as the core raw material, and the ring stiffness can generally reach SN12.5 and above. It can withstand lateral pressure and axial thrust during jacking, and is not easy to deform and break. Its inner wall has a low coefficient of smooth friction and small jacking resistance. It is suitable for crossing pipe jacking operations ranging from 30 meters to 200 meters. No additional anti-corrosion treatment is required. It can be applied to various geological conditions in hilly areas of Hubei or plains.

MPP power pipelines cover multiple types of municipal infrastructure scenarios

In addition to road jacking, MPP power pipelines can also be adapted to various municipal infrastructure scenarios such as municipal power grid transformation, industrial park power matching, rail transit power pre-embedding, and urban comprehensive pipe gallery power warehouses. The high temperature resistance property can withstand the operating temperature of high-voltage cables above 10kV, and the insulation is strong. It is not easy to cause leakage hazards. The conventional service life can reach more than 50 years. The later operation and maintenance cost is much lower than that of traditional pipes. It has now become the mainstream selection for the laying of power pipelines in Hubei municipal infrastructure.

Precautions for MPP Pipe Selection in Pipe Jacking Project

When selecting MPP power pipelines for pipeline jacking projects, it is necessary to match the corresponding ring stiffness products according to the jacking distance, burial depth, and geological conditions. Long-distance pipe jacking is recommended to choose pipes with a wall thickness greater than 12mm. The interface adopts a hot-melt docking process. Before construction, the appearance of the pipes should be checked for cracks and depressions to avoid leakage and fracture problems during the jacking process. The products must meet the general standards of municipal power pipes to ensure the long-term use quality of the project.
