FIELD: construction.SUBSTANCE: retaining wall according to the first version is made of tubular sheet piles. At least some piles are equipped with a seasonal cooling device of any available type. Cooling devices are so arranged in the sheet pile to provide for contact of their upper part with atmospheric air. The retaining wall according to the second version comprises seasonal cooling devices made in the form of an air circulation pipe. The cooling devices are placed inside the inner cavity of tubular sheet piles and are installed coaxially or with displacement relative to the axis of the tubular sheet pile. The air circulation pipe is connected in the upper part to atmosphere with the help of a covered hole. The lower part of the pipe is brought near the permafrost soil of the base.EFFECT: environmental safety, reduced costs, increased reliability of design and lower labour intensiveness of construction.10 cl, 4 dwg |
