Ground Movement in Hard Rock Conditions Related to Pipe Bursting

Pipe bursting in hard to medium rock presents significant cost advantage in addition to many other known advantages compared to open cut pipe replacement. However, the owners of nearby utilities and structures and all the involved parties in the project have valid concerns about the ground movements in these conditions due to pipe bursting. Theoretically, in tight rock trenches, the bursting head applied considerable amount of energy to create a pathway for the new pipe. Ground movements resulting from that energy may be considerable and may cause significant damage to nearby utilities, structures, and pavement. These concerns may unjustifiably prohibit the utilization of an economical option with less risk and disturbance than open cut. Bowling Green State University, with the support of the pipe bursting and the Ohio construction industries, conducted a research project to evaluate the ground movement associated with pipe bursting in rock conditions to investigate the safe distance for building and utilities from pipe bursting operations. This paper presents the measured ground movement within the theoretical wedge of ground movement due to the bursting process under several variables such as trench width, bedding material, degree of up-sizing, and proximity to existing services. The research also considered the ground movement associated with the pneumatic and static pull bursting systems.
