METHOD FOR BUILDING AN UNDERGROUND CONSTRUCTION, PARTICULARLY A VEHICLE PARK, WHILE LEAVING IN PLACE OBSTACLES SUCH AS TREES.

摘要

A method is provided for building an underground construction, particularly a vehicle park, while leaving in place obstacles which are at least partially buried around the edge of the construction, e.g. trees. Before digging is begun, a curtain of elongate retaining elements for the obstacles is constructed from the surface, said elements being driven into the ground substantially around the edge of the construction, so as to be inclined outwards underneath said obstacles (6).
