As the national requirement on durable pipe network for water supply and sewerage is getting much higher than before, not only should the design and selection of materials consider one-time investment, cost performance and comprehensive cost, but also tend to consider the same materials of pipes and its fittings to improve the full cycle service life. The new XTJ ductile iron pipe jacking products adopt the ductile iron self-anchored pipe fittings of the same material at the turning up and down points where the pipeline crosses the river and highway. It not only ensures the high standard full cycle life of the pipeline, but also reduces the secondary environmental pollution caused by the excavation, without affection on highway traffic. Starting from the development backgrou����Ϸappnd of XTJ ductile iron pipe jacking, this article introduces the same material design concept, characteristics and performance verification of XTJ ductile iron pipe jacking, and expounds the application of XTJ ductile iron pipe jacking in case of drinking water diversion project from Xujiahe River to Anlu City, Hubei Province.
