Hydraulic Joint for Pipe Jacking
Publication: Journal of Construction Engineering and Management
Volume 135, Issue 6
Abstract
A newly developed hydraulic joint for pipe jacking is described and compared with conventional compression rings. It is shown that with the hydraulic joint, thrust eccentricities are largely reduced, resulting in a much more uniform stress profile at the pipe ends and hence a considerably reduced pipe damage potential. Higher jacking forces can be applied (fewer or no intermediate jacking stations are necessary), longer pipes can be used (fewer joints are necessary), smaller radii of curvature are feasible (fewer or no intermediate jacking pits are necessary) and frictional forces are reduced. The measurement of joint displacements and joint liquid pressures permits an effective real-time monitoring of the jacking process. 30 of the 40 pipelines with a total length of completed so far had curved alignments. The smallest radius of curvature was using long pipes with an internal diameter of . Practical experiences gained with the hydraulic joint are summarized.
