FR2493099A1 - Watering device for plants grown e.g. on patio - comprises tanks joined along side walls by tubular slotted elements with aligned holes in side walls permitting free flow of water - Google Patents

Abstract

A series of tanks under the earth are connected together at their corners by thermo-formed polypropylene, tubular elements. These have longitudinal slots in their walls so as to fit over the rims of adjacent tanks. The walls of the tanks have aligned openings sealed together to permit the passage of water from one to the other. A system of wicks supplies water by capillary action to a thin layer of absorbent material lying between the overlying earth and the tanks.

Description

WET FLOORS are load-bearing assemblies produced by the judicious assembly of simple industrial components. They provide
Buried WATER RESERVES, intended for the humidification of the earth fillings in the case of plantations on "SLAB" (Parking slab, Hanging gardens,
Planter boxes for Public space, private terraces accessible) whose reception surface has good @ orizontality.

The technique of humidification of earth fillings by capillary rise is already used in the case of plantations in small tanks with water reserve for ornamental crops in a protected environment (housing, offices, public premises.) The process presented uses this technique, but releases its application to the field of outdoor plantings. This process concerns all the equipment of outdoor spaces that can be planted on DALLE.

The known equipment intended for the humification of the grounds, are very often systems of automatic watering by surface diffusers. The operation of watering preserves the same periodicity (Bi-daily in dry season) Excess water is not recoverable .Other devices make it possible to retain a certain quantity of water, but one cannot really speak of RESERVE ".

In the vast majority of cases, the water flows, penetrates into the earth by gravity and produces the leaching of the mixture (Elimination of rich substances).

The device according to the invention makes it possible to store a certain amount of water (approximately 60 liters / m2) in a network of BACS t'capteurs "(2/3 figA) assembled together. These BACS are provided with 32 m orifices / m in the upper part of the vertical walls (9/3 detail ab) These orifices ensure (a) The free circulation of water, thus distributed homogeneously over the entire surface to be fitted. They also allow (b) assembly trays between them, this operation is carried out by the installation of thermo-formed "WALL PASSAGES" (3/3 ab).

(c) finally on some of these orifices will be fixed, the filling spout (s), as well as the evacuation of the overflow.

 The nesting system of the present process is obtained by wicks made of POLYESTER fibers (I / 3.C) intended to wet a DISTRIBUTOR FABRIC (non-woven, bi-directional) I / 3 .Ybidim) which transmits to the cultivation soil (chosen according to the plants used) The advantage of such a process lies in the fact that it is possible to carry out equipment "TYPE WATER RESERVE of all surfaces, to postpone operations watering qelx i rÇ? sïe% Ires weeks depending on the case, the site the region, the plants ...) Water splashes are avoided (remarkable in the case of surface watering) no damage from the compost, the sneering substances of the mixture are stored in the water in RESERV @, possibly, it is possible to enrich the water stored by additions of culture (fertilizers, treatment products, etc.) liquid.

When installing the sets - water reserved for this device, the @ACS SENSORS are filled with a calibrated POUZZOLANE charge, which will provide mechanical support.

@ e @@ e @ ou @ e of pozzolana (0.200) will also have a draining effect and, insulating from the fact that it is represented in the schematic diagram 1/3 we observe the elements
@ o @ stitutive of the present process, In the order of their implementation, A.-Sensor tanks e @ black polypropyllue 30/10 (fig A.2 / 3) The format of these tanks is not limiting. B.- PROTECTIVE WICKERS in black polypropylene 50/10 (Fig. 2/3) This element is placed, either efourc @ enment on four bins (Large surface equipment) or erfour @ ement on two bins (linear equipment ) or in the center of a ba @ in the case of one-off equipment, (Planter).

@ .- Installation of feeders in polyester fibers # 10m / m (One per square meter approximately) Fixing of the tanks between them by the installation of
WALL PASSAGES (detail ab 3/3) the rigid assembly formed by the trays is then filled with the pozzolan filling (e1 / 3) then the BIDTM distribution fabric (1/3) is installed over the entire surface of the part equipped, IT will no longer be left to garnish with the land selected by the culture specialist.

As in all equipment of this type, the permanent humidification system is started by abundant sprinkling over the entire surface, so as to thoroughly wet the assembly and transmit water to the various elements of the device. (Distributor fabrics, wicks, soil ...)
Devices of this type (prototypes) have been put in place, the performance of these prototypes proves the interest of such devices.

The devices which are the subject of the present invention can be used whenever the layout of a space needs to be vegetated. They are especially suitable when connections to the water network are impossible or expensive. Or, in the case where the watering operation is delicate (site inaccessible).

In the case of private terraces, it is the absence of the user which imposes the device with water reserve, in fact, in the case of prolonged absence (annual holidays) watering is lacking, the life of the is threatened. It is therefore in the c @ a @ tiers of the @@ ements, for Urban Space, Public spaces, Green spaces, Ect parking slab ... But also in the case of particular applications , storage of plants, Greenhouses, nursery warehouses that @UMIDES FLOORS will be implemented.

Claims (1)

 REDI CATIONS FLOORS @ UMIDFS, produced by the assembly of simple industrial components for the @ umidification of the linings of cultivated earth in the case of planata have on "DALLE". @ WET FLOORS according to claim N 1 characterized by the assembly of the sensor tanks (water reserve) by thermo-formed polypropylene pieces, these tubular pieces @ ensure the free circulation of water during the filling operation of this device. @ WET FLOORS according to claim N 2 characterized by the assembly of the sensor tanks using wall passages on the @aute part of the banks (fig A 2/3) Long x Width (these dimensions are variable) which allows bi-directional installation. WET FLOORS according to claim N03, characterized by the assembly of the sensor trays by means of the passage of walls on the upper part of the banks, which ensures high security in the event of accidental leakage. In this case, each container being isolated, the risk is limited to the 60 liters m2 represented by the maximum capacity of a container. WET FLOORS according to claim N04 characterized by the load-bearing appearance of the products obtained by filling the BACS with the load of POUZZOLANE.
