Because hot air welding is adopted, hot melt lap joint is not needed, open fire is not needed, and therefore the insulation layer can be directly laid in an empty space, a protective layer is saved, and the construction period and the cost are saved.

Preferably, the waterproof layer is made of a non-curable waterproof coating material.

The traditional waterproof layer only adopts the mode that waterproofing membrane laid, because waterproofing membrane itself's characteristic is hardly fully glued with the basic unit completely, site operation thickness homogeneity also is difficult to control, and the overlap edge is more, and the construction is complicated. The non-curing waterproof material is directly constructed on the shot-throwing layer, so that the uniformity of the thickness of the waterproof layer is improved, full adhesion of the top plate is easy to realize, the potential hazards caused by lap joint of the coiled materials are overcome, and the influence of uneven thickness caused by coating construction factors is avoided.

The non-cured composite waterproof layer is directly constructed on the shot-blasting layer, and the composite waterproof layer is manufactured by directly compounding the self-adhesive waterproof roll layer in the spraying or blade coating process, so that the waterproof roll layer has the structural characteristics of uniform thickness of the waterproof roll and reliable detailed treatment of waterproof paint, full adhesion of the top plate is easily realized, the potential hazard possibly caused by roll lapping is overcome, and the influence of uneven thickness possibly caused by paint construction factors is avoided.

As preferred scheme, the roof is planted to building species prevents that row holds system still includes drainage blanket and filter layer, and the drainage blanket is laid on resistant root puncture waterproof layer, and the filter layer is laid on the drainage blanket, and drainage blanket and drainage system intercommunication.

The drainage blanket has replaced the screed-coat among the traditional system and has looked for the slope layer, and the drainage blanket can guarantee to plant the roof and have unblocked drainage space, and the filter layer can effectively block soil granule to pass through to prevent to cause the soil body to destroy because the excessive loss of soil granule, allow the water or the gas in the soil to pass through the fabric and freely discharge simultaneously.

Preferably, the drainage layer comprises a drainage plate, and a plurality of support columns are uniformly distributed on the surface of the drainage plate.

In one example, the drainage plate adopts a grid type drainage plate, the grid type drainage plate is made of polyvinyl chloride (PVC) pure raw materials, no recycled materials are added, the decomposition and the degradation are avoided, and the flexibility and the tensile property are good.

The compressive strength of the drainage plate is more than or equal to 350 Kpa. According to the regulation in the roofing project quality acceptance specification GB 50207-2012: "plastic drainage plates are generally not provided with any protective layer". According to the regulation in the national standard 'planting roof building structure atlas 14J 206': "no slope layer may be provided when structural slope finding or reliable drainage measures are employed". Therefore, the leveling layer and the leveling layer are cancelled, and the drainage plate is directly paved.

The requirements of the drainage plate are as follows:

1. the density of the drain board material reaches 1.4, and the physical property is stable.

2. The drainage plate is provided with a plurality of collapse-proof supporting columns, so that the geotextile does not collapse after being covered with soil, and the smooth drainage space of the planting top plate is ensured.

In one example, in a planting roof anti-drainage and storage system of an underground building, such as an underground garage, a water outlet of a drainage system is arranged at the edge of the underground garage, the water outlet of the drainage system is connected with a water inlet of an observation well, the water inlet of the observation well is lower than the arrangement of the roof of the underground garage, and the water outlet of the observation well is connected with a reservoir or a municipal pipe network, so that rapid drainage is realized.

In one example, the permeate collection tubes are staggered across the root-piercing-resistant waterproof layer such that the permeate collection tubes form drainage channels in a grid-like arrangement between drainage plates, and water on the drainage plates permeates into the permeate collection tubes and is discharged from a water outlet of the drainage system.

As preferred scheme, the heat preservation is bilayer structure, including first heat preservation and second heat preservation, first heat preservation and second heat preservation crisscross setting each other. The heat preservation adopts bilayer structure, and the overlap joint of first heat preservation and the overlap joint of second heat preservation should the staggered joint installation, avoids forming the logical seam and influences the heat preservation effect.

In one example, the lap joint should be closely and smoothly taken care of during the laying process of the heat-insulating layer, and the installation of the heat-insulating layer and the subsequent construction of the waterproof layer should be carried out synchronously, so that the heat-insulating layer is prevented from being wetted by water. If the corners of the insulating layer are damaged, the insulating layer should be cut neatly and laid.

Preferably, the heat-insulating layer is a polystyrene heat-insulating plate, and the compressive strength of the heat-insulating layer is greater than or equal to 350 Kpa.

Specifically, the compressive strength is generally not required to the heat preservation of present planting roof, and owing to the compressive strength is not enough in the practical application, often after the construction of follow-up heat preservation upper portion waterproof layer is accomplished, cross operation causes local heat preservation to warp great, tears the waterproof layer of destroying its upper portion, and the waterproof effect that keeps warm worsens, therefore the heat preservation adopts the polystyrene heat insulation board that compressive strength is greater than or equal to 350Kpa, improves the compressive strength of heat preservation, avoids the heat preservation deformation.

As the preferred scheme, the building species plants the roof and prevents arranging the system of holding still including planting the soil layer, plants the soil layer and lays on the filter layer. And (4) paving planting soil on the filter layer, and planting vegetation on the planting soil.

The vent pipe enables the drainage layer to be communicated with the external atmospheric pressure, so that pressure difference is formed between the drainage groove and the seepage water collecting pipe, and the drainage plate is convenient to drain water into the seepage water collecting pipe.

Preferably, the filter layer is polypropylene geotextile.

The filtering layer adopts filament polypropylene geotextile to replace the commonly used polyester geotextile in daily life. The filter layer can effectively prevent soil particles from passing through, thereby preventing the soil body from being damaged due to excessive loss of the soil particles, and simultaneously allowing water or gas in the soil to freely discharge through the fabric. The polypropylene material is very stable and hardly reacts with other reagents except concentrated sulfuric acid and concentrated nitric acid. According to the actual test result, the polypropylene geotextile can almost keep 100 percent of strength after being soaked in the calcium hydroxide solution at 60 ℃ for three days, and the strength loss rate of the polyester geotextile can reach 10 to 15 percent. If the soaking time is longer, the polyester material will continue to hydrolyze until it disappears. The polyester hydrolysate terephthalic acid and ethylene glycol belong to toxic substances, and the water content should not exceed 0.1mg/L and 1mg/L respectively. Therefore, from the aspect of environmental safety, the polyester geotextile is not suitable for being used as a filter layer in the drainage system of the planting roof of the underground building. Also under the same conditions, the density of polypropylene is only 0.91g/cm3, the lightest of the common polymers. The polyester had a density of 1.38g/cm3, which was 1.5 times that of polypropylene. Therefore, under the condition of the same unit area weight, the polypropylene geotextile has more fibers, and accordingly has better functions of strength, isolation, reverse filtration, protection and the like.
