非开挖导向强度分析及其在电力铺管设计中的应用

Analysis on Trenchless Build-up Strength and the Application in the Design of Electric Power Pipe-laying

全面分析了非开挖铺管导向钻进轨迹设计的主要决定因素;合理地剖析了钻遇地层的性质及其它施工条件对导向强度的影响;提出导向强度的计算方法,更科学、准确地设计出导向孔轨迹,并应用到实际电力管道铺设导向孔三维轨迹设计中。

This paper roundly analyzed the main determinants of the trenchless pipe-laying in the track-oriented design, and reasonably analyzed the stratum properties and other construction conditions which impact on the build-up strength. Calculating method of build-up strength was put forward, which is more scientific and accurate in designing the pilot hole track, and could be applied in the three-dimensional track design for electric power pipe-laying.
