Waterproof structure for ground source heat pump pipe penetrating through concrete foundation slab and construction method thereof

The invention discloses a waterproof structure for a ground source heat pump pipe penetrating through a concrete foundation slab and a construction method thereof. The problem of how to guarantee thewaterproof engineering quality of the portion where the ground source heat pump pipe penetrates through an underground garage foundation structure slab is solved. The outer side face of a ground source heat pump slab penetrating sleeve (1) is provided with a sleeve upper end flange and a sleeve lower end flange, a fine stone concrete protective layer (10) is arranged under the reinforced concretefoundation slab (11), a double-layer modified asphalt waterproof coiled material layer (8) is arranged under the fine stone concrete protective layer (10), a modified asphalt waterproof paint layer (7) is arranged under the double-layer modified asphalt waterproof coiled material layer (8), the sleeve lower end flange (2) is arranged under the modified asphalt waterproof paint layer (7), a fine stone concrete cushion layer
