Abstract: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. |
