METHOD AND APPARATUS FOR THE BOTTOM-UP CONSTRUCTION OF VERTICAL RISERS FROM UNDERGROUND PASSES THROUGH THE SOIL, USING A PIPE JACKING EQUIPMENT

摘要

A “Riser Concept” Method and Apparatus includes the bottom-up construction of vertical risers from underground passes through the soil, using a pipe jacking equipment. The pipe jacking equipment vertically push the riser pipe from underground pass upwards through soil formations to waterbody, air intake, terrain surface or like. The method and mechanism can be applied either in traditionally bored tunnel or in tunnel bored by tunnel boring machine.
