| Abstract: | It is of great significance for municipal pipeline engineering construction to implement 3-D horizontal directional drilling(HDD).In virtue of a practical project,this work carries out the onsite monitoring of a gas pipeline during 3-D HDD construction.Based on gyroscopic position-detection system and a fiber optic sensing technique,an integrated scheme for the pipeline construction monitoring is designed and conducted.The 3-D spatial coordinates of the overall pipeline are measured.The mechanic responses of the tested section running through the whole drilling track are obtained.It testifies that the longitudinal strains and the sectional moments are sharply increased as the tested pipe traverses with a rotation simultaneously on the horizontal and vertical planes.The recorded data are informative for a further theoretical analysis and the monitoring strategy can provide a reference for such similar projects. |
