METHOD OF STRENGTHENING A WEAK BOTTOM SOIL IN THE CONDITIONS OF THE ICE COVER THE WATER AREA

摘要

FIELD: construction.;SUBSTANCE: invention relates to hydraulic engineering, in particular to a method for strengthening weak bottom soils during the formation of underwater bases. Method of strengthening the weak bottom soil in the conditions of the ice cover of the water area includes the formation of a ground-cement pile array by the jet cementation method using process equipment. Technological equipment is placed on the ice cover, for which the thickness of the ice cover is preliminarily examined at the place where technological equipment is located and around it to determine carrying capacity thereof, which makes it possible to place technological equipment on it, and in case of insufficiency of the mentioned bearing capacity, the thickness of the above-mentioned ice cover increases thickness thereof by frozen additional ice layers with appropriate reinforcement or without it, and then in the thickness of the ice form openings for the passage of technological equipment.;EFFECT: technical result consists in ensuring the strengthening of a weak bottom soil, which allows to form a pile array capable of perceiving significant load bearing loads, in the regions with ice cover the water area, in particular in arctic conditions, while simultaneously reducing the construction period and material intensity during the formation of the underwater base.;1 cl
