Pipe Jacking Services
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.
It is an essential pre-requisite for any potential pipejack to complete a thorough study of the prevailing geology to be made available to all interested parties at an early stage. This is the only way of ensuring a cost-effective solution to any given problem. The Pipe Jacking technique is for installing underground pipelines, ducts and culverts without the use of open trenches.
Powerful hydraulic jacks are used to push specially designed pipes through the ground behind a shield at the same time as excavation is taking place within the shield. The technique ensures a structural sound and watertight finished pipeline.There is no theoretical limit to the length of individual pipe jacks although practical engineering considerations and costs may impose restrictions. Drives of several hundred metres either in a straight line or to a radius are routine have been completed by Jacked pipelines. Construction tolerances are compatible with other tunneling methods and the pipe jacking method generally requires less over-break than segmental tunnels, providing better ground support.
