摘要:- 随着国家对城镇给排水管道使用寿命要求越来越高，设计不仅要考虑一次性投资，更要考虑管材的性价比及综合造价，还要趋向于管线同材质设计以提高其全周期使用年限。新型XTJ球墨铸铁顶管在穿越河道、公路上下翻及碰头处采用同材质球铁自锚管件，既保证了高标准的管线全周期寿命，又减少了开挖造成的二次环境污染，且不影响公路施工标段的交通。从XTJ球墨铸铁顶管的开发背景入手，介绍了XTJ球墨铸铁顶管的同材质设计理念、特点与性能验证，并结合湖北省安陆市“引徐济安”饮水工程实例对XTJ球墨铸铁顶管的应用进行了阐述。
Abstract:- 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 background 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.
