A DEFLECTING MODULE FOR AN ANTI-SAND BARRIER, A BARRIER THUS OBTAINED AND A PROTECTION METHOD FROM WINDBLOWN SAND

摘要

The invention relates to a deflecting module (1) suitable for creating barriers against an incoming multiphase flow, specifically windblown sand (S), comprising a first support portion (2) with inclination ranging between 70° and 110° relative to the ground (T) and able to be fixedly connected to a corresponding foundation (5), a second support portion (3) and a deflecting panel (4) supported by the second support portion (3), wherein the deflecting panel (4) and the second support portion (3) have a concave profile relative to the direction of the incoming flow; the invention also relates to a barrier (B) obtained by combining a plurality of deflecting modules (1) for protecting a man-made work (M) by trapping the windblown sand (S); the invention also relates to a protection method of a man-made work (M) from windblown sand using at least one barrier (B). The preferred and advantageous application of the deflecting module, the barrier and the method according to the present invention resides in protecting transport and industrial line-like infrastructures, civil and industrial settlements, farms and cultivated areas, archaeological sites and the like and, more precisely, the deflecting module, the barrier and the method according to the present invention are preferably used to shelter communication lines and/ or buildings by separating them from the surrounding environment; the present invention is particularly suitable for use in desert and semi-desert regions, especially in very windy areas and also with multidirectional sand-laden winds.
