FIELD: construction.
SUBSTANCE: invention is related to construction of tunnels under water. Method for construction of fully or partially submerged tunnel on natural or artificial sea bottom ground, in which tunnel is built of serial tunnel sections. Standard submersible section is arranged on sea bottom ground by means of installation suitable for operation in submerged condition, which is shifted forward when required in water along sea bottom ground along line marked for tunnel passage, moreover, mentioned installation comprises sealed working space with atmospheric pressure intended for location of personnel and equipment needed for erection and setting of installation in place. Tunnel tightness is maintained in process of its construction. Quire considerable space for communication is preserved open between already built section of tunnel and working space of installation for erection and assembly of new section. Tunnel in process of its construction is used when necessary for transportation of section composite parts to installation.
EFFECT: reduction of time needed for construction and reduction of its material intensity.
