QA and QC for Jacking for Small Diameters
In the same way as the jacking method for medium to large diameter, controls for progress, material and equipment, work, safety and pollution are highlighted for QA and QC for small diameters jacking. Small diameter jacking have some specific problems such as: impossible jacking, zigzag line, pipe break, surface settling, groundwater inflow, damage to other utility lines. Man-entry is not possible for small diameters. So the excavation face cannot be checked directly visually. Furthermore, even in case of emergency, human operation is impossible in the tunnel. For this reason, it is expensive to control the emerging situation. Therefore, QA and QC requires special attention.
