FIELD: construction. ^ SUBSTANCE: method to erect a foundation on heaving soils includes installation of a foundation slab and heat insulation material onto a levelled base. A sliding layer is laid on the prepared base, and a multi-layer spatial foundation platform, comprising heat insulation material, is erected in a monolithic manner. The lower reinforced concrete slab is formed with vertical reinforcement rods protruding into crossing ribs along the entire height of the platform. Heat insulation material is laid onto the lower reinforced concrete slab with the possibility to arrange a system of crossing ribs. Crossing ribs are formed. An intermediate reinforced concrete slab is formed, the second layer of heat insulation material is set on it. Cross ribs are formed, and the upper reinforced concrete slab is formed, besides, the vertical reinforcement rods are connected to reinforcement of all slab layers. ^ EFFECT: reduced labour costs, provision of heat insulation material durability against potential damage, higher spatial stiffness of the foundation slab and its distributing capacity, provision of protection against frost swelling. ^ 3 cl, 1 dwg |
