EFFECTIVE TECHNOLOGY OF CONSTRUCTING EARTH STRUCTURES.

An effective technology of constructing earth structures was developed and introduced on the construction of the flood-control complex of Leningrad, which after correlating to other local conditions can be successfully used in many other cases of hydrotechnical practice. The complex of structures, isolating the Neva Bay when catastrophic sea waves and storm winds approach from the Gulf of Finland and thereby protecting the city from destructive consequences of flooding, is located at a site between the populated area of Gorskaya, Kronshtadt, and Bronka. The layout consists of 11 earth and rock dikes, two navigation structures, and six aqueducts. This complex, large, and diverse hydro development consists of objects, structures, and mechanisms, many of which in such a combination do not have any analogues. The main characteristic consists in that the bulk of the construction and installation works is accounted for by the construction of the protective dikes, cofferdams, and other useful earth embankments.
