Method for the construction of a structure under an embankment supporting a railway track or a roadway

摘要

The procedure is carried out by constructing or laying a flat guide platform (2) on at least one side of the embankment excavation to support a concrete tunnel structure or frame (13) and connecting it to traction cables (6) inserted through channels in the platform. One end of each cable is connected to a fixed anchoring point (12) on the platform, while the other is connected to a power cylinder (21) which enables the structure to be slid into position inside the embankment excavation on a layer of a lubricating agent between the structure's base slab (14) and platform.
