Abstract (en)
[origin: EP1793047A1] A method of building a shallow-depth tunnel at the bottom of a water area and a system used to implement it present a technology of driving a tunnel for vehicle traffic or other-purpose tunnel under the river channel or under the bottom of other shallow water area. They can be predominantly used to form a temporary enclosure for a closed bottom segment in the water area and the space above it throughout the depth of water. A distinctive feature of the method is that a bottomless hydraulic enclosure with controlled buoyancy is used in it. This enclosure is made at a plant as a single closed structure capable of bearing on it detachable crane equipment, construction platforms and amenity rooms.
