    System of protection in works of the sand transported by the wind and procedure of installation. It comprises a modular structure formed by a succession of screens 1, each of which includes a base 4 that supports a floor and a front partition 5; where the front partition 5 separates an inner part 11b where the base 4 and the work to be protected are located, and an outer part 11a corresponding with a face of the front partition 5 against which impacts a flow of sand transported by the wind. The base 4 has on its lower face in contact with the ground, longitudinal ribs 10 that are nailed in the ground as means for retaining and anchoring the screen 1. On an upper face of the base 4 a sand mass is deposited as additional means to hold and stabilize each screen 1. (Machine-translation by Google Translate, not legally binding)

    In one embodiment, the longitudinal ribs are portions of the bases delimited by U-shaped cuts; wherein said portions have been folded down to constitute said longitudinal ribs and also through openings
    22
    On the floor of the outer part of the system of the invention are located longitudinal pits formed by the extraction of a mass of sand that is deposited on the bases of the screens.
    The longitudinal end section of the screens forms an acute angle with respect to a surface that is a continuation of the support surface on the floor on which each screen sits through its base; where said acute angle is delimited between 20º and 45º.
    In the screens of the first embodiment and of the third embodiment (screens formed by steel mesh), the base and the front partition of each screen form an angle of less than 90 °.
    An installation procedure comprises the following phases: - placing the succession of screens on the ground in parallel along the work / installation to be protected and in a direction substantially perpendicular to the wind direction. -extraction of a mass of sand from the outer part of the soil for the formation of longitudinal pits. -vert the mass of sand extracted from the longitudinal pits on the bases of the screens.
    On the other hand, as the years go by, around the modular structure formed by the succession of screens an accumulation of sand is generated, it being necessary to disassemble said modular structure and reassemble it so that the protection system of the invention, as described below, according to the following additional phases: - disassemble the screens by raising them upwards; where in this operation the sand masses deposited in the bases are discharged through the through openings of said bases; where said discharge is carried out on the ground surface

    The succession of screens 1 overlap one another by their extreme sections delimiting intermediate spaces 6, through which it can be passed to carry out the maintenance of the modular structure, as well as the assembly and disassembly by a crane vehicle, being able to carry out other necessary operations. The screens 1 are arranged in successive parallel directions that form complementary angles with respect to the direction parallel to the work to be protected.
    Each of the screens 1 comprises an angular configuration formed by two planes forming an acute angle, which in a preferred embodiment is 60 °. One of said planes comprises a base 4 that sits on the ground, while the other even plane comprises a front partition 5 inclined with respect to a vertical plane. The base 4 and the front partition 5 are rounded together by an arcuate section
    7.
    On the other hand, the base 4 of the screen 1 includes a longitudinal end section 8 located in an upwardly inclined plane that forms an acute angle with respect to a surface that is a continuation of the support surface on the ground on which it sits the screen through its base 4. In one embodiment said acute angle has a value between 20 ° and 45 °, having a preferred value of 30 °.
    The base 4 of the screen 1 has the upper face on which sand is deposited and a contrasted lower face from which longitudinal ribs 10 that are driven into the ground to get a better fixation of the screen 1. Said ribs 10 have an inclination convergent towards the front partition 5 of the screen 1, while in a preferred embodiment of the invention each longitudinal rib 10 is arranged in a plane delimited between two complementary angles of 45 ° and 135 ° taking as reference the base 4 of the screen 1 .
    The base 4 and the front partition 5 together with the arcuate section 7 and longitudinal end section 8, delimit an enveloping space 9; where said longitudinal end section 8 helps to keep the pile of sand stably on the base 4 of the screen 1.

    The manipulation of the new inverted T-shaped screen 1 'is carried out by means of two anchor bolts 18 that are fixed to the upper spine 25 and are also fixed to the longitudinal profile 26 by means of opposing nuts 19 and washers 20 as in the case of the screens 1 of angular structure.
    One of the two vertical planes of the inverted T-shaped 5 'double frontal partition has a face on which the wind strikes, while the other even vertical plane has a face that is located in the internal part 11b where the work is located to protect
    The new 1 ’inverted T-shaped screen has a symmetrical configuration that facilitates transport and stacking.
    On the other hand, although there is a possibility that the bases 4, 4 'of the screens 1,1' incorporate the longitudinal ribs 10 without including the through openings 22, said longitudinal ribs 10 are normally included in combination with the through openings 22, so that in this case the longitudinal ribs 10 is a part of the material of the bases 4, 4 'that have been constituted by making U-shaped cuts on said bases 4, 4' delimiting portions that have then been folded down to constitute said longitudinal ribs 10.
    A variant of the system of the invention, which is less heavy but cheaper and equally effective, is the placement of 1’’angular screens made of galvanized steel mesh or other non-biodegradable material with reticles of dimensions from 15 x15 cm. up to 30x30 cm. and 10 mm diameter bars .; this diameter may be different and the reticles may also have other dimensions than those described.
    On the vertical plane of each 1 '' steel mesh screen, a canvas or woodland branches from pruning is fixed by plugging the gaps of the mesh, and on the horizontal plane that rests on the floor a fabric of artificial fabric is placed then deposit the earth or sand from the excavation of pit 12 in front of screens 1 '' on the outside 11a. In this embodiment of mesh, independent pieces 27 are integrated that integrate lower extensions that constitute the
