Anti-freezing treatment method for concrete structure foundation in severe cold region

摘要: The invention discloses an anti-freezing treatment method for a concrete structure foundation in severe cold region. includes steps of 1, construction adhesion layer; 2, frost heaving preventing and 3, backfilling the foundation. layer heating asphalt to completely melted state, dehydrating asphalt, uniformly coating on outer surface treated foundation, cooling form membrane so that is obtained. 201, stewing mixture materials layer, adding asbestos powder stirring talcum then as obtain 202, layer. mass ratio 1.0+/-0.01:0.34+/-0.02:0.11+/-0.02. has simple steps, low investment cost, convenient construction, fine effect, can effectively relieve or eliminate damage due force, increases structure, quality be guaranteed easily.
