METHOD FOR FLOATING STEEL TUNNEL TUBES LINED WITH CONCRETE INTO POSITION

摘要

The invention is characterized in that tunnel tubes are manufactured from steel into any shape whereby being capable of providing support, after which they are lined with concrete according to the manner in which they are to be used, and are maximally equipped with the required installations. Assembly and manufacturing are carried out on dry land in a building pit, which is kept dry by deep wells and whose bottom depth enables the highest structural element of the tunnel tubes to be floated, after flooding, into a tunnel-like shoring construction of the ditch channel created. The recovered groundwater can be constantly supplied to a third use. When crossing flowing bodies of water, the locking union of the channel tunnel shoring is provided with a flat shape. The locking union prevents foreign bodies from floating into the tunnel shoring and is capable of being reused.
