本powerpoint演示文稿提供了使用球墨铸铁管/高密度聚乙烯（HDPE）管进行水平定向钻井的背景信息。 设计考虑， 技术选择，以及 介绍了施工阶段。 结论是:球墨铸铁通过硬盘安装，可能不会 适合狭窄区域； HDPE的弯曲性能更适合 两个地点； 符合许可证和设计要求；和 艾拉镇最终以6个过境点中的4个而告终 通过转换为千斤顶和钻孔来进行倾斜。包括表格、数字。

This powerpoint presentation provides background information on horizontal directional drilling with ductile iron pipe/high density polyethylene (HDPE) pipe. Design considerations, technology options, and construction phase are presented. Conclusions were that: Ductile Iron by HDD installation, may not be suitable for tight areas; Bending properties of HDPE was better suited for the 2 locations; Met permit and design requirements; and, Ira Township ended up with 4 out 6 crossings with DIP by converting to Jack and Bore. Includes tables, figures.
