Embodiment 1
[0026] Such as figure 1 A waterproof layer structure for the ground of the parking lot is shown, including plain soil rammed bottom layer 1, on top of plain soil rammed bottom layer 1, concrete floor 2, cement mortar leveling layer 3, and SBS modified layer are laid sequentially from bottom to top Asphalt waterproof coiled material 4, cement mortar protective layer 5, first reinforced concrete layer 6, ceramsite concrete layer 7, second reinforced concrete layer 8, and concrete surface layer 9. The concrete bottom plate 2 is C30 waterproof concrete with an impervious pressure of 0.6 MPa. Wherein, the ceramsite in the ceramsite concrete layer is the fly ash ceramsite of particle diameter 5mm, and its thermal conductivity is 0.6W / (m·k); The weight ratio of cement mortar is cement:sand:water=1:3:0.6. The surface of the SBS modified asphalt waterproof membrane 4 is coated with asphalt mastic. Both the first reinforced concrete layer 6 and the second reinforced concrete layer 8 ...
Embodiment 2
[0028] Such as figure 1 A waterproof layer structure for the ground of the parking lot is shown, including plain soil rammed bottom layer 1, on top of plain soil rammed bottom layer 1, concrete floor 2, cement mortar leveling layer 3, and SBS modified layer are laid sequentially from bottom to top Asphalt waterproof coiled material 4, cement mortar protective layer 5, first reinforced concrete layer 6, ceramsite concrete layer 7, second reinforced concrete layer 8, and concrete surface layer 9. Wherein, the ceramsite in the ceramsite concrete layer is fly ash ceramsite with a particle size of 20 mm, and its thermal conductivity is 0.45 W / (m·k); the concrete bottom plate 2 is C30 waterproof concrete with an impervious pressure of 2.5 MPa. The weight ratio of the cement mortar used in the cement mortar leveling layer 3 and the cement mortar protective layer 5 is: cement:sand:water=1:3:0.6. The surface of the SBS modified asphalt waterproof membrane 4 is coated with asphalt mast...
