Description

DESCRIZ IONE DESCRIPTION

La presente invenzione riguarda il settore dell? impermeabilizzazione mediante guaina in PVC. In particolare trattasi di una speciale flangia che consente di attraversare la guaina impermeabile con comuni tubazioni in PVC per il trasporto di liquidi mantenendo il sistema a completa tenuta idraulica anche sotto battente idraulico. The present invention relates to the sector of? waterproofing with PVC sheath. In particular, it is a special flange that allows to cross the waterproof sheath with common PVC pipes for the transport of liquids, keeping the system completely watertight even under the hydraulic head.

La flangia ? stata altres? progettata in modo tale da poter essere montata per consentire qualsiasi direzione di scorrimento del liquido all?interno del tubo (flangia bidirezionale). La flangia consente l?innesto rapido dei tubi in PVC mediante semplice incollaggio e pu? essere montata indistintamente su una o sull?altra faccia (a mezzo di saldatura a caldo con macchine specifiche) della stessa guaina impermeabile. The flange? was also? designed in such a way that it can be mounted to allow any direction of liquid flow inside the pipe (bidirectional flange). The flange allows the quick connection of PVC pipes by simple gluing and can? be mounted indistinctly on one or on the other side (by means of heat welding with specific machines) of the same waterproof sheath.

Il richiedente si occupa di progettazione e realizzazione di impianti di fitodepurazione dal 1998. The applicant has been involved in the design and construction of phytodepuration plants since 1998.

La fitodepurazione ? un sistema di depurazione naturale per il trattamento delle acque di scarico domestiche, assimilate a domestiche (ad es. cantine vitivinicole) ed industriali. Gli impianti di fitodepurazione si possono dividere in due tipologie: flusso sommerso e flusso superficiale. Constructed wetlands? a natural purification system for the treatment of domestic, similar to domestic (eg wine cellars) and industrial waste water. Constructed wetlands can be divided into two types: submerged flow and surface flow.

Gli impianti a flusso sommerso sono costituiti da un bacino impermeabilizzato riempito con materiale inerte e piantumato con apposite essenze vegetali che, in collaborazione con i batteri che si formano sugli inerti, contribuiscono alla degradazione degli inquinanti. Il refluo da trattare scorre sotto la superficie degli inerti. Il bacino ? costituito da uno scavo di profondit? compresa tra 0,8 m e 1 m e superficie variabile in base alla composizione dello scarico da trattare. Submerged flow systems consist of a waterproofed basin filled with inert material and planted with specific plant essences which, in collaboration with the bacteria that form on the aggregates, contribute to the degradation of pollutants. The wastewater to be treated flows under the surface of the aggregates. The basin ? consists of an excavation of depth? between 0.8 m and 1 m and variable surface according to the composition of the drain to be treated.

Alla seconda tipologia di impianti, invece, appartengono veri e propri laghetti in cui l?acqua da trattare scorre a pelo libero e alla depurazione partecipano piante acquatiche. Il bacino impermeabilizzato possiede profondit? in genere di circa 0,6 m. The second type of plants, on the other hand, belong to real lakes in which the water to be treated flows free-flowing and aquatic plants participate in the purification. The waterproofed basin has depth? typically about 0.6 m.

In entrambi i casi all?uscita si ottiene un?acqua depurata a norma di legge che pu? essere smaltita in corpi idrici superficiali, sul suolo 0 riutilizzata a fini irrigui. In both cases at the outlet you get a purified water according to the law that can? be disposed of in surface water bodies, on the ground or reused for irrigation purposes.

Per l?impermeabilizzazione dei bacini possono essere utilizzate guaine in PVC, PE oppure direttamente vasche prefabbricate in vetroresina. Di norma si prediligono le guaine poich? consentono di variare la superficie e la profondit? dello scavo in base alle esigenze progettuali; in particolare Ini tram Impresa Italia S.r.l. (il richiedente) realizza gli impianti di fitodepurazione utilizzando guaine in PVC. For the waterproofing of the basins, PVC, PE sheaths or directly prefabricated fiberglass tanks can be used. As a rule, sheaths are preferred since? allow you to vary the surface and depth? excavation based on design requirements; in particular Ini tram Impresa Italia S.r.l. (the applicant) builds the constructed wetlands using PVC sheaths.

In entrata ed in uscita all?impianto tali guaine devono essere attraversate da tubazioni di immissione e raccolta del refluo: tali punti di attraversamento rappresentano i punti critici per la tenuta idraulica del sistema che, per evitare fuoriuscite di liquidi inquinanti neH?ambiente, deve essere garantita nel tempo. L?attraversamento della guaina viene realizzata saldando a caldo oppure incollando la tubazione alla guaina oppure mediante flangie a bulloni (con le quali ? necessario realizzare un foro per ogni bullone aumentando cos? il rischio di perdite). Entrambi i sistemi non garantiscono la tenuta idraulica e peraltro non sono neppure di facile esecuzione. At the inlet and outlet of the plant, these sheaths must be crossed by inlet and collection pipes of the wastewater: these crossing points represent the critical points for the hydraulic seal of the system which, to avoid leakage of polluting liquids into the environment, must be guaranteed over time. The crossing of the sheath is made by hot welding or gluing the pipe to the sheath or by means of bolt flanges (with which it is necessary to make a hole for each bolt, thus increasing the risk of leaks). Both systems do not guarantee the hydraulic seal and, moreover, they are not easy to perform either.

Per risolvere questo problema nel 2002 il richiedente brevetta un kit che comprende, tra l?altro, un sistema speciale per l?attraversamento della guaina di PVC a garanzia di perfetta tenuta idraulica ed estremamente semplice da utilizzare. Tale sistema ? costituito da una bocchetta di PVC (detta anche ?messicano?) al cui interno ? incollato un raccordo di PVC rigido per l?innesto del tubo in PVC pressione. La bocchetta viene montata internamente al bacino e resa solidale alla guaina mediante saldatura a caldo mentre il tubo viene semplicemente incollato alla flangia con apposito collante per PVC (per sua costituzione detta flangia ? considerata monodirezionale e pu? essere quindi montata solo sulla faccia interna della guaina impermeabile che riveste il bacino per garantirne la tenuta idraulica). To solve this problem, in 2002 the applicant patents a kit which includes, among other things, a special system for crossing the PVC sheath to guarantee perfect hydraulic sealing and extremely simple to use. Such a system? consisting of a PVC vent (also called? Mexican?) inside which? glued a rigid PVC fitting for the connection of the pressure PVC pipe. The nozzle is mounted inside the basin and made integral with the sheath by heat welding while the pipe is simply glued to the flange with a special adhesive for PVC (by its constitution, said flange is considered one-way and can therefore be mounted only on the inner face of the sheath waterproof covering the basin to ensure its hydraulic seal).

Successivamente, grazie a questo trovato, Initram Impresa Italia S.r.l. inizia a commercializzare un kit in scatola che pu? essere facilmente spedito ovunque. Il prodotto comprende, oltre all? impiantistica, una guaina di PVC presaldata in pezzo unico completa del suddetto sistema di innesto delle tubazioni e permette cos? la realizzazione di impianti di fitodepurazione senza l?intervento di personale specializzato in quanto non prevede alcun tipo di saldatura. Subsequently, thanks to this invention, Initram Impresa Italia S.r.l. begins to market a boxed kit that can? be easily shipped anywhere. The product includes, in addition to? plant engineering, a pre-welded PVC sheath in a single piece complete with the aforementioned coupling system of the pipes and allows cos? the construction of phytodepuration plants without the intervention of specialized personnel as it does not require any type of welding.

L?invenzione oggetto della presente richiesta consiste in una nuova flangia in PVC derivata da quella contenuta nel kit precedentemente descritto: detta flangia ? realizzata in un unico pezzo ed ? formata da una base circolare (1) e da una parte cilindrica (7) con foro centrale (la forma resta sempre quella di un ?messicano?). The invention which is the subject of the present request consists of a new PVC flange derived from the one contained in the previously described kit: said flange? made in one piece and? formed by a circular base (1) and a cylindrical part (7) with a central hole (the shape always remains that of a? Mexican?).

Mediante saldatura a caldo la base (1) della flangia viene resa solidale alla guaina ?? PVC (8) garantendo la perfetta tenuta idraulica del sistema. By means of heat welding the base (1) of the flange is made integral with the sheath ?? PVC (8) ensuring the perfect hydraulic seal of the system.

Nella parte cilindrica della flangia (7) si innestano le tubazioni che attraversano la guaina. The pipes passing through the sheath are inserted into the cylindrical part of the flange (7).

Una peculiarit? del nuovo trovato ? quello di essere bidirezionale, ovverosia la base (1) pu? essere saldata alla guaina (8) sia internamente (13) (come avveniva con il precedente trovato) che esternamente (14) al bacino da impermeabilizzare (12). La parte interna della flangia, infatti, ? realizzata in modo che le tubazioni in PVC possano essere innestate sia sul lato anteriore (5) che su quello posteriore (6) della flangia stessa. All? interno della flangia si innestano tubazioni a pressione in PVC mediante semplice incollaggio. A tale scopo sono presenti degli orli di battuta di ?fermo corsa? (2,3) per consentire il corretto inserimento dei tubi durante l?innesto. A peculiarity? of the new found? that of being bidirectional, that is, the base (1) can? be welded to the sheath (8) both internally (13) (as was the case with the previous invention) and externally (14) to the basin to be waterproofed (12). The internal part of the flange, in fact,? made so that the PVC pipes can be inserted both on the front (5) and on the rear (6) side of the flange itself. All? inside the flange, pressure pipes in PVC are inserted by simple gluing. For this purpose, there are stop edges of? Stroke stop? (2,3) to allow correct insertion of the tubes during coupling.

Sulla superficie esterna del cilindro della flangia inoltre ? possibile innestare una tubazione (10) con diametro pari al diametro esterno della flangia stessa. On the outer surface of the flange cylinder also? It is possible to insert a pipe (10) with a diameter equal to the external diameter of the flange itself.

Questo trovato garantisce la tenuta idraulica del sistema nel tempo in quanto non sono possibili infiltrazioni di liquido n? tra la guaina e la flangia (mediante saldatura a caldo le due parti vengono fuse insieme) n? tra la flangia ed i tubi (i tubi in PVC pressione aderiscono perfettamente all?interno della flangia utilizzando l?apposito collante per PVC). This invention guarantees the hydraulic seal of the system over time as no liquid infiltrations are possible. between the sheath and the flange (by heat welding the two parts are fused together) n? between the flange and the pipes (the pressure PVC pipes adhere perfectly to the inside of the flange using the special adhesive for PVC).

Detta flangia pu? essere realizzata con qualsiasi diametro per consentire l?attraversamento della guaina con le tubazioni in PVC pi? diffuse in commercio. Said flange can? be made with any diameter to allow the penetration of the sheath with the PVC pipes pi? widespread on the market.

Detta flangia, inoltre, pu? essere prodotta con stampaggio monocomponente o pluricomponente. Moreover, said flange can? be produced with single-component or multi-component molding.

Questo nuovo trovato ? utilizzabile per ? impermeabilizzazione e la gestione ottimale di impianti di fitodepurazione, di bacini di contenimento, laghetti, piscine, coperture varie. This new found? usable for? waterproofing and optimal management of constructed wetlands, containment basins, ponds, swimming pools, various coverings.
