Open face excavation method is the oldest form of pipe jacking method. This method provides an open excavation face access and the ability for the removal of man made obstacles and boulders. The spoil is removed by the conveyor and spoil trolleys which are winched out. The hydraulic jacks pushing the pipes are held by the main jacking frame and are part of the jacking rig. The jacking rig, jacking shield & other hydraulic equipment is powered by portable diesel hydraulic power-pack situated outside of the launch pit. The jacking frame transfers the horizontal loads from the jacks back to the thrust wall. Open face excavation involves the usage of hydraulic jacks, which provides the necessary driving force for thrusting specially designed pipes and / or culverts directly into the ground while excavation of soil is taking place from within manually or mechanically depending on the type of machine used. This jacking method provides a structurally flexible and watertight finished conduit.
