The invention discloses an
overwintering protection coiled material for seasonal frozen soil
engineering and a construction method, the efficient
overwintering protection coiled material is formed through cooperative operation of a heat preservation coiled material and a
moisture absorption coiled material; and from the mechanism of seasonal frozen soil generation, excessive
moisture in a near surface soil layer is absorbed through the
moisture absorption coiled material; water freezing and downward development in the near-surface soil layer are avoided;, meanwhile, trace heat release is stable in the near-
surface water absorption process, the temperature of air in the coiled material covering layer can be increased, and formation and development of frozen soil are further avoided; the
moisture absorption coiled material is covered with the heat preservation coiled material for heat preservation, the temperature near the
earth surface is effectively kept, and
frost heaving damage is prevented. On the basis of traditional single heat preservation, the function of absorbing moisture in soil in a near-surface area of a project is added,
frost heaving disasters are fundamentally prevented, and better heat preservation and anti-freezing effects are scientifically and effectively achieved; the near-surface soil layer fully dried by the
moisture absorption coiled material becomes a part of the whole heat preservation
system, and formation of seasonal frozen soil is further prevented.
