Definitions

• the invention relates to a plant surface installation method, on a facade or a roof or as a system of cultivation above ground, waterproof and liquid fertilizers, whose supports and trays are made by folding and welding of thin sheets of stainless steel or galvanized steel.
• the tanks used for revegetation arise in the same way as a surface of photovoltaic panels that can provide the electricity needed for pumps used for watering plants. The whole is then autonomously energy.
• the creation of plant facades is a major architectural and ecological challenge in urban areas.
• This type of double skin installed on the facade or the roof of the building has many advantages.
• the facade or the green roof are for example acoustic attenuators, thermal regulators, and contribute to biodiversity in urban areas.
• the techniques for greening facades or roofs are: walls of climbing vines, climbing plants on cables, stacked garden walls or walls strewn with pots.
• Another embodiment consists of plant surfaces fixed on non-woven thick felt, itself hung on the facade.
• a polymer sheet is used to protect the wall from corrosion by liquid effluents.
• a disadvantage of these types of installation is that, under the effect of thermal cycles due to temperature differences, the polymer sheets or the trays fixed on the facade or roof eventually tear around the screws used for fixing the system on the wall causing leakage of fertilizer liquids.
• Another common embodiment of this type of plant façade, installed in double skin, consists of a plurality of bins, generally made of plastics fixed on the wall, receiving one or more species of plants per tray.
• bins or pockets created in felts, are filled with substrate for growing plants.
• substrate for growing plants The following are generally used: clay balls, pozzolana, draining substrates, for example sphagnum, or rockwool.
• a disadvantage of this type of installations is that the plant surfaces produced are generally not waterproof. If we want to install them on the roof, these systems need to put under the roof, or on the facade, under the plant structure, a layer of polymer to protect walls and under roof.
• Watering and fertilization in liquid fertilizer varies depending on the type of substrate. It is, for example continuous for clay balls, pozzolan, nonwoven felt and drip type for other types of substrates. Some plant walls installed on felts are continuously watered and consume several cubic meters of fertilizer water per day.
• Substrate irrigation is usually by gravitation.
• Fertilizer adduction is done on the upper edge of the vats of plants, or on the upper edge of several rows of vats of plants, which induces a heterogeneous watering.
• the object of the present invention is to overcome these disadvantages by proposing a system for placing bins to be planted whose surface of the assembled bins is waterproof.
• This system can be installed on the roof or facade of buildings, or on properly defined supports.
• the system must be compatible with the installation system of photovoltaic modules that will provide the energy autonomy necessary for the operation of the irrigation pumps.
• This system must be compatible in particular with the installation system of photovoltaic modules described in patents FR 2 915 217-A1 and EP 209 668 1-A1.
• the object of the invention is to provide a plant surface installation system, on the roof or facade of the buildings or for an above-ground culture, meeting the following principles:
• the plant structure must be detached from the wall, to prevent liquid fertilizers or irrigation water from corroding the surface of the building.
• the system of assembled tanks must be watertight overall, not only for each module, it must protect the roof or the facade of a possible leakage of irrigation tubes or soluble fertilizer
• the plant tank system installed on the roof can replace the tiles.
• the system of assembled tanks must allow the flow of rainwater or irrigation overflows on the surface of the plant structure.
• the system of the assembled bins must make it possible to recover from treating or recycling the surplus of phytosanitary products and liquid fertilizers so that they are not rejected directly to the sewer.
• the system must be reasonably airtight to improve the thermal of the building.
• the plant surface installation system must allow either pre-cultivated modules to be installed or plants to be planted in situ.
• the system must be able to change or remove individual greenery modules because the living matter is destined to disappear and regenerate.
• the plant facade must withstand the shock, as well as the pressure or the depression of a strong wind. Irrigation tubes should be masked and made inaccessible except for maintenance personnel.
• the system must be able to block the slippage of the culture substrates when they are installed on a slope or facade.
• the system must make it possible to install, on the same surface, photovoltaic modules and vegetal modules while sealing them.
• the plant system must therefore ensure continuity in the installation technique of the different types of facade cladding.
• the system must allow the passage of properly insulated electrical cables, for example:
• Electric cables used for measurement or lighting, and liquid fertilizer supply tubes, must be masked and rendered inaccessible except to maintenance personnel.
