Abstract:
The hydrological and geological data of Songhuajiang River in Jilin Province are analyzed and the analytical results will be adopted in Changchun-Jilin Oil Pipeline Crossing project. Two programs, the horizontal directional drilling crossing and tunnel crossing, are compared. The candidate is determined as the horizontal directional drilling crossing with casting-pushing to separate stone formation. This article introduced the design and installation requirements in selection of crossing formation and crossing in-out-point, the determination of design parameters, crossing technical measures and stone formation crossing.
