Description
Descrizione Description
L’invenzione in oggetto consiste in un sistema di stabilizzazione dei pendìi e contemporanea raccolta di acqua piovana mediante un insieme di dreni sotterranei e vasche di raccolta. The invention in question consists of a slope stabilization system and simultaneous collection of rainwater by means of a set of underground drains and collection tanks.
Nelle zone collinari, coltivate o incolte, nei periodi di intense e prolungate piogge si verifica lo scivolamento verso valle dei terreni superficiali a causa dell’eccessivo accumulo di acqua nel terreno. In hilly areas, cultivated or uncultivated, during periods of intense and prolonged rain, surface soils slide towards the valley due to the excessive accumulation of water in the ground.
Tale fenomeno può essere arginato attraverso un impianto di drenaggio sotterraneo, posto in opera al di sotto del piano di coltivo, in grado di desaturare i primi strati di terreno. I drenaggi deprimono le pressioni neutre nel sottosuolo e di conseguenza incrementano la resistenza del terreno. Il sistema di drenaggio è inoltre utile ad evitare la saturazione del suolo per insufficiente capacità di assorbimento migliorando la consistenza del terreno e la sua aerazione in modo da favorire una maggiore presenza di nutrienti e quindi di migliorare la lavorazione della terra così come la trasformazione delle sostanze organiche in sostanze come i minerali che possono essere assimilati dalle piante, incrementando la qualità delle coltivazioni. This phenomenon can be stemmed through an underground drainage system, placed below the cultivation level, capable of desaturating the first layers of soil. Drainage depresses the neutral pressures in the subsoil and consequently increases the resistance of the soil. The drainage system is also useful to avoid soil saturation due to insufficient absorption capacity by improving the consistency of the soil and its aeration in order to favor a greater presence of nutrients and therefore to improve the tillage as well as the transformation of substances. organic in substances such as minerals that can be assimilated by plants, increasing the quality of crops.
Tale sistema di drenaggio essendo posizionato di sotto al piano di coltivo non è di intralcio alle usuali attività agricole. This drainage system, being positioned below the cultivation level, does not hinder the usual agricultural activities.
L’impianto consiste in una serie di tubi dreni disposti a spina di pesce lungo i pendìi con un passo ed un inclinazione prestabilito. Il passo dei dreni è variabile e serve a regolare la quantità d’acqua potenzialmente emungibile durante la pioggia. The system consists of a series of drainage pipes arranged in a herringbone pattern along the slopes with a predetermined pitch and inclination. The step of the drains is variable and serves to regulate the amount of water that can be extracted during rain.
La rete di tubi dreni sotterranea in più collettori acclivi The network of underground drainage pipes in several steep collectors
Il sistema di collettori è intervallato da vasche di accumulo lungo il versante. Le dimensioni delle vasche di accumulo sono tali da realizzare una riserva irrigua atta a garantire il fabbisogno estivo di una predeterminata superficie di terreno limitrofa all’impianto installato. The collector system is interspersed with accumulation tanks along the slope. The dimensions of the accumulation tanks are such as to create an irrigation reserve capable of guaranteeing the summer needs of a predetermined surface of land adjacent to the installed system.
L’ irrigazione dei terreni avviene quasi esclusivamente con impianto a caduta sfruttando la prevalenza piezometrica associata all’acqua raccolta nelle vasche di accumulo a monte. Le vasche vengono dotate di un impianto di troppo pieno sversante nella vasca successiva lungo il pendio, garantendo che la riserva idrica accumulata non ecceda una predeterminata soglia di sicurezza (Fig. 2.1). All’imbocco del tubo di troppo pieno, di ogni singola vasca, viene installato un “ sifone di sicurezza autoadescante" (Fig. 2.2) che pesca l’acqua ad una profondità stabilita; tale sifone evita l’occlusione del tubo di troppo pieno da possibili corpi galleggianti a pelo libero e con il foro superiore permette il disinnesco in automatico dello stesso quando il livello del’acqua nella vasca scende sotto il livello del foro, consentendo di conservare la riserva d’acqua al livello (F). The irrigation of the land takes place almost exclusively with a drop system exploiting the piezometric head associated with the water collected in the upstream storage tanks. The tanks are equipped with an overflow system that flows into the next tank along the slope, ensuring that the accumulated water reserve does not exceed a predetermined safety threshold (Fig. 2.1). A "self-priming safety siphon" (Fig. 2.2) is installed at the inlet of the overflow pipe of each individual tank, which draws the water at a set depth; this siphon avoids clogging of the overflow pipe from possible floating bodies with free surface and with the upper hole it allows the automatic disengagement of the same when the water level in the tank drops below the level of the hole, allowing to keep the water reserve at level (F).
I tubi collettori dei dreni disposti lungo il pendio sono dotati, all’estremità sversante nelle vasche di raccolta, di un sistema in grado di regolare il flusso dell’acqua emunta in funzione del livello dell’acqua presenta nella rispettiva vasca di accumulo (Fig. 2.3). The drainage pipes arranged along the slope are equipped, at the end flowing into the collection tanks, with a system capable of regulating the flow of the discharged water according to the level of the water present in the respective accumulation tank (Fig. 2.3).
I collettori di raccolta finali possono essere convogliati in un apposito lago artificiale di accumulo, posto a valle dell’intero sistema, a servizio dei terreni agricoli e/o delle zone industriali a valle del bacino stesso. The final collection collectors can be conveyed to a special artificial storage lake, located downstream of the entire system, serving agricultural land and / or industrial areas downstream of the basin itself.
In sintesi l’invenzione applicata sul territorio, realizza un'azione congiunta di difesa del suolo, riducendo il rischio di frane superficiali in pendìi potenzialmente instabili, e di valorizzazione agricola, in virtù della maggiore lavorabilità del terreno e della possibilità di sfruttare la riserva idrica accumulata. In summary, the invention applied on the territory, carries out a joint action of soil defense, reducing the risk of surface landslides on potentially unstable slopes, and of agricultural enhancement, by virtue of the greater workability of the soil and the possibility of exploiting the water reserve. accumulated.
L’invenzione inoltre rispetta tutti i principi alla base dello sviluppo sostenibile, poiché permette di irrigare il terreno con acqua che altrimenti andrebbe dispersa. Tra l’altro, salvo eccezioni, l impianto permette di irrigare i terreni limitrofi senza utilizzare energia di pompaggio, ma sfruttando la prevalenza piezometrica dell’acqua accumulata nelle vasche. The invention also respects all the principles underlying sustainable development, since it allows the soil to be irrigated with water that would otherwise be dispersed. Among other things, with some exceptions, the system allows you to irrigate the neighboring lands without using pumping energy, but by exploiting the piezometric head of the water accumulated in the tanks.
