METHOD TO MANUFACTURE TECHNOLOGICAL WALL OF FOUNDATION PIT

摘要

FIELD: construction. ^ SUBSTANCE: method to manufacture a technological wall of a foundation put by means of submersion of a row of rabbets into soil and subsequent installation of facilities to protect against soil collapse into the foundation pint between them. The operation for installation of facilities to protect against soil collapse into the foundation pit is carried out by at least partial submersion of a row of double-phased thermal siphons into soul at the outer side from the rabbets relative to the foundation pit, at the depth that is larger than that of the foundation pit, and by subsequent cooling of upper sections of thermal siphons until a solid frozen wall is formed that contacts with rabbets. ^ EFFECT: increased strength of the wall under bending loads at the side of soil, provides for impermeability for underground waters. ^ 7 cl, 1 dwg
