    RADICULAR CONTROL DEVICE FOR URBAN TREE DESCRIPTION
    OBJECT OF THE INVENTION
    The present invention falls within the technical field of garden irrigation, more specifically in that of irrigation systems that use perforated pipes placed in the ground, as well as in the containers for cultivation, and refers in particular to a device of growth control of woodland roots, specially designed for urban areas. BACKGROUND OF THE INVENTION
    The vital space of a tree is constituted by the aerial part, comprised of leaves, branches and trunk, and by the underground part, occupied by the roots. Although the depth and extension of the root system are very variable, it usually occupies a space equivalent to or greater than that of the aerial part.
    The roots are responsible for fixing the plant in the soil and for the absorption of the raw material thanks to the non-woody roots or absorbent hairs. The root system can be pivotal, with a single main root down and from which the secondary roots grow, or branched, that is, formed by several main roots.
    In the urban environment, a tree faces a series of adverse conditions with respect to those of the natural environment, among which a lower incidence of solar radiation, the reverberation of light caused by surrounding buildings, a greater radiation artificial, the existence of frequent air currents and channeled wind, generally higher temperatures, intense evapotranspiration, a low hygrometric rate, greater presence of pollutants and a great competition for space.
    The root system of trees planted in urban areas has for its part a plurality of particular problems, such as the waterproofing to which the soil is subjected, a lower availability of water, little volume available for root growth and development, scarcity of available organic matter, chemical imbalances in the soil derived from poor nutrition, unstructured and compacted soils or low levels of O2 that lead to situations of root asphyxiation.

    On the other hand, the lack of control over the proliferation of secondary roots in an upward direction towards the surface, in search of moisture, causes deterioration of surface paving due to the pressure exerted on the base layer of said paving, both sidewalks and vials In a first phase, said deterioration consists of a bulging of the surface of said pavement, which, if not corrected in time, can in a second phase break or tear it, with the consequent danger to vehicles and pedestrians and the high costs derived from the relevant repairs. DESCRIPTION OF THE INVENTION
    The object of the invention consists of a root control device, especially designed for plants located in urbanized areas, which avoids the problems derived from an uncontrolled growth of said roots mentioned above.
    To this end, the device comprises an alcorque provided with a central hole intended to house the base of a tree trunk, a plurality of wells defined in the ground around the hole of the tree, an irrigation system and a physical barrier to prevent ascent from the roots to the surface.
    The wells, of essentially cylindrical geometry, are defined on the ground with a radial arrangement with respect to the trunk of the tree and are filled with a porous material, preferably sand.
    The irrigation system, which is preferably drip type, comprises a plurality of irrigation pipes corresponding to the plurality of wells defined in the ground, which apply a flow of water from a general pipeline in order to create some humid conditions inside each of their respective wells, to attract the growth of the roots of the tree towards these wells and thus avoid an upward growth towards the surface in their search for available water, which ends up causing problems in the pavement previously mentioned.
    image3
    Optionally, the irrigation system comprises regulation means such as an irrigation programmer and a plurality of regulation valves in correspondence with each of the irrigation pipes.
    For those cases in which, in spite of the wet conditions created artificially in the wells, some roots would grow upwards, the installation of a physical barrier is foreseen, which intervenes in said growth and redirects the roots towards the interior of the land.
    Said physical barrier preferably comprises a screen of essentially truncated conical geometry with the trunk of the tree, made of a material that cannot be broken by the roots, preferably polypropylene or PVC.
    It is envisaged that, in order to avoid discontinuities in the pavement in which the alcorque is defined, it is covered by means of protection, preferably a relay.
    The root control device for urban trees described in this way is a simple, economical and versatile solution to prevent uncontrolled upward growth of these roots, avoiding the problems of pavement breakage and the associated risks and costs described above. DESCRIPTION OF THE DRAWINGS
    To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical implementation thereof, a set of drawings is attached as an integral part of said description. where, for illustrative and non-limiting purposes, the following has been represented:
    image4
    Figure 1.-Shows a top perspective view of the root control device, in which its main constituent elements are appreciated.
    Figure 2.- Shows a plan view of the device.
    Figure 3.- Shows a frontal view of a longitudinal section of the device, in which the growth of the roots attracted towards the wells in search of moisture is appreciated. PREFERRED EMBODIMENT OF THE INVENTION
    Next, a detailed explanation of a preferred embodiment of the object of the present invention is provided with the aid of the aforementioned figures.
    The described root control device for urban trees, shown schematically in figure 1, is formed by an essentially quadrangular geometry (1), in whose center a cylindrical hole (2) is defined to accommodate the base of the trunk (3) of a tree, a plurality of wells (4), an irrigation system and a physical barrier (5).
    The hole (2) is entirely surrounded by the plurality of wells (4) of essentially cylindrical geometry defined in the ground and arranged uniformly and radially with respect to its center, as illustrated in Figure 2. The wells (4) are They fill in their entirety with a porous sand.
    The preferred embodiment described herein comprises eight wells (4) with diametral dimensions of 20 centimeters and a depth of 1.50 meters, defined uniformly along a circular area of 1.50 meters radius with respect to the center of the hole (2 ).
    The irrigation system comprises a plurality of irrigation pipes (6) in correspondence with each of the wells (4), and a branch (7) that starts from a general water pipe (8). Each of the irrigation pipes (6) is arranged in an essentially coincident position with the center of the well (4), and runs it longitudinally from its upper end to its lower end.
    image5
    The branch (7) comprises a first straight section (9) and a second section (10) of essentially annular geometry, arranged in a concentric position outside the hole
    (2) defined in the alcorque (1). The first section (9) takes a flow of water from the general pipeline (8) and channels it to the second section (10), from which the irrigation pipes (6) lower to the lower end of each of the wells (4), the second section (10) distributing said flow evenly between each of the irrigation pipes (6).
    In this preferred embodiment, the irrigation pipes (6) are specific for drip irrigation and have a diameter of 16 millimeters, and apply the flow of water from the bypass (7), with diametral dimensions of 50 millimeters, taken from the general conduction (8), located along the depth of each of the wells (4) in which they are located, to create humidity conditions capable of attracting the roots of the tree towards said wells (4 ).
    It is envisaged that the irrigation system will additionally comprise regulating means, not shown in the attached figures, to determine the applied flow rate. In the preferred embodiment described herein, the regulating means comprise an irrigation programmer and a plurality of regulating valves, in correspondence with each of the irrigation pipes (6).
    The physical barrier (5) comprises an essentially truncated conical geometry screen buried in the ground and arranged concentrically and inferior to the hole (2) of the tree shaft (1), as shown in Figure 1. Said physical barrier (5) avoids the growth of the roots towards the surface getting in their way and redirecting them towards the bottom of the ground.
    To prevent the roots from crossing said barrier (5), the screen is made of a material resistant to root pressure, which in this preferred embodiment is polypropylene.
    Finally, a grid (11) superficially covers the tree shaft (1), both to protect the


    base of the trunk (3) of the tree and the underlying installation to make up the alcorque
    (1) with the surrounding pavement and thus avoid discontinuities that could cause trips and accidents to both pedestrians and vehicles.
    5 The installation of the root control device for urban trees thus described begins with the excavation of a radial area around the trunk of the tree, in which the wells (4) are practiced and the elements of the irrigation system are incorporated. Subsequently, the wells (4) are filled with sand and the barrier (5) is arranged to prevent growth towards the surface of the roots.
    10 At a later stage, the entire pre-excavated radial area is filled with nutrient-rich soil readily available for the roots, taking care to leave the irrigation system regulation means easily accessible for adjustments and repairs in a simple way. Finally the alcorque is defined (1)
    15 by work, and is covered with the grid (11).
