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...

Abstract

The invention discloses a waterproof layer structure for a parking lot ground. The waterproof layer structure comprises a packed soil bottom layer, and a concrete base plate, a cement mortar screeding layer, an SBS modified asphalt waterproof sheet material, a cement mortar protection layer, a first reinforced concrete layer, a ceramsite concrete layer, a second reinforced concrete layer and a concrete surface layer are sequentially laid on the packed soil bottom layer from bottom to top. The waterproof layer structure for the parking lot ground solves the problem that an existing waterproof layer is likely to lose efficacy and leaks water, and achieves the purposes of improving the waterproof effect and prolonging the service life.

Description

technical field [0001] The invention relates to the field of civil construction, in particular to a waterproof layer structure used on the ground of a parking lot. Background technique [0002] Ground waterproofing is an important link in civil construction, occupies an important position in the field of construction engineering, and is an important link to ensure that the entire engineering structure is not eroded by water. Most of the existing ground waterproofing measures use flexible waterproof membranes to isolate water, and then lay cement mortar on them. The waterproof performance is reduced or even completely ineffective, which brings a lot of inconvenience to later use. Especially for the ground of the parking lot, due to the long-term heavy load and the constant changes in the load of vehicles driving in and out, it is more prone to waterproof failure. Contents of the invention [0003] The purpose of the present invention is to provide a waterproof layer struc...
