METHOD FOR BUILDING TUNNEL BRIDGE IN UNDERWATER CHANNEL FOR OVERCOMING SHALLOW OBSTACLES Russian patent published in 2016 - IPC E02D29/09 

FIELD: construction.

SUBSTANCE: invention relates to construction, particularly, to underwater structures built below bed surface level. Method for construction of tunnel bridge in underwater channel for overcoming shallow crossings involves construction of underwater channel and building underwater structure on its bottom, which is covered with protective casing. Underwater structure is made in form of tunnel bridge, which is built along underwater channel with arrangement of entries and exits into/from tunnel bridge on banks of crossing; tunnel walls are made as retaining walls, which are attached to steel-concrete pillars, fixed in bottom of underwater channel, and coated with plastic sheets. Protective casing is made of steel concrete, tightly placed on retaining walls above tunnel bridge, and also covered with plastic sheets.

EFFECT: technical result consists in providing security and favourable operation conditions in tunnel bridge, reduction of material and labour expenditures for tunnel bridge construction.
