Description
Descrizione a corredo di una domanda di Brevetto per Invenzione industriale per il trovato avente per titolo: “Elementi modulari di complemento per la realizzazione di rilevati in terra rinforzata rinverdibile”. Description accompanying a patent application for an industrial invention for the invention entitled: “Modular complementary elements for the construction of embankments in re-greenable reinforced earth”.
TESTO DELLA DESIZIONE TEXT OF THE DESITION
La presente invenzione si riferisce ad elementi modulari che trovano impiego nella realizzazione di rilevati costruiti con la già diffusa tecnica delle terre rinforzate, con la finalità di facilitarne il rinverdimento della scarpata, di proteggere il rinforzo strutturale del rilevato, di migliorare la stabilità del fronte e di semplificare le operazioni di posa in opera. The present invention refers to modular elements that are used in the construction of embankments built with the already widespread technique of reinforced earth, with the aim of facilitating the greening of the slope, protecting the structural reinforcement of the embankment, improving the stability of the face and to simplify the installation operations.
E<'>nota allo stato della tecnica, una metodologia costruttiva per la realizzazione di rilevati conosciuta come "terra rinforzata<"'>a paramento rinverdibile. A construction methodology for the construction of embankments known as "reinforced earth <" '> with a green facing is known to the state of the art.
Nelle terre rinforzate a paramento rinverdibile di uso comune, il rinforzo è costituito da una geogriglia sintetica o da una rete metallica assemblate con la tecnica “wrap-around<”>, che vede il telo costituente il rinforzo strutturale risvoltarsi prima sul paramento e poi sulla parte superiore, per garantire un ancoraggio anti-sfilamento. fati rinforzi strutturali sono, quindi, costituiti da "reti<">le cui maglie hanno aperture che variano da un minimo di 20 nini a oltre 100 mm. a seconda del tipo di rinforzo utilizzato. In commonly used reverdable reinforced soils, the reinforcement is made up of a synthetic geogrid or a metal mesh assembled with the "wrap-around <"> technique, which sees the sheet constituting the structural reinforcement turn up first on the facing and then on the upper part, to ensure an anti-slipping anchorage. The structural reinforcements are therefore made up of "nets <"> whose meshes have openings ranging from a minimum of 20 nini to over 100 mm. depending on the type of reinforcement used.
Secondo l<'>uso corrente, onde evitare il dilavamento del terreno, viene posizionato un elemento di contenimento, di natura vegetale (biorete o biostuoia) o sintetica (georete o geostuoia) sulla parte frontale di ciascuno strato del rilevato, la cui funzione, soprattutto nel caso di elementi biodegradabili, viene a perdersi col tempo; ovvero assicura l integrità del paramento fino a quando non vi sia un efficace copertura vegetale in grado di effettuare una protezione naturale e duratura. Sempre secondo l uso corrente, viene anche sovente impiegato un cassero a perdere in rete elettrosaldata con funzione di sostegno per il paramento a vista e di armatura atta a consentire la compattazione del materiale posto in prossimità del paramento del rilevato. Nei sistemi di tipi' noto sopra descritti uno dei principali inconvenienti dipende dal fatto che talvolta non si realizza un adeguata copertura vegetale.. Ciò può accadere per il mancato impiego di terreno vegetale di buona qualità e per uno spessore sufficiente (circa 30-40 cm) alle immediate spalle del paramento. Un altra frequente causa del mancato rinverdimento è la presenza diffusa di pietre o di spazi vuoti dovuti ad insufficiente compattazione della parte frontale, durante la fase di posa in opera, spesso dovuta alla scomoda posizione di lavoro obbligata dall inclinazione del paramento. Questi vuoti determinano movimenti di terreno dovuti ad assestamento e difficoltà di attecchimento della vegetazione seminata o spontanea che sia. ulteriori cause possono derivare dalla cattiva qualità della semina, specie se viene effettuata solo la semina manuale a spaglio, strato per strato, durante la costruzione del rilevato anziché un idrosemina potenziata. Da ultimo, quale causa di mancalo rinverdimento, si indica l eccessiva aridità del fronte, che. per la sua inclinazione, non raccoglie sufficiente quantità di acqua piovana, According to the current use, in order to avoid the washout of the ground, a containment element, of a vegetable nature (bio-mesh or biomat) or synthetic (geonet or geomat) is placed on the front part of each layer of the embankment, whose function, especially in the case of biodegradable elements, it gets lost over time; that is, it ensures the integrity of the facing until there is an effective plant cover capable of providing natural and lasting protection. Always according to current use, a disposable formwork in electro-welded mesh is also often used as a support for the exposed facing and reinforcement to allow the compacting of the material placed near the facing of the embankment. In the systems of known types described above, one of the main drawbacks depends on the fact that sometimes an adequate vegetation cover is not achieved. ) behind the facing. Another frequent cause of the lack of greening is the widespread presence of stones or empty spaces due to insufficient compaction of the front part, during the installation phase, often due to the uncomfortable working position required by the inclination of the facing. These voids cause ground movements due to settlement and difficulty in taking root of the sown or spontaneous vegetation. further causes may derive from poor sowing quality, especially if only manual broadcast sowing is carried out, layer by layer, during the construction of the embankment instead of an enhanced hydroseeding. Lastly, as a cause of lack of greening, the excessive dryness of the front is indicated, which. due to its inclination, it does not collect sufficient quantities of rainwater,
l a presente invenzione si propone di ovviare ai sopraccitati inconvenienti realizzando un elemento modulare da posizionare, in corso d opera, nella zona frontale dei rilevati costruiti con terre rinforzate rinvendibili sopra descritte. The present invention aims to obviate the aforementioned drawbacks by providing a modular element to be positioned, during construction, in the front area of the embankments constructed with re-salable reinforced earth described above.
Tale elemento modulare ha una forma prismatica o trapezoidale in cui il lato inclinato viene a costituire il paramento frontale ed è realizzalo di terricciato o composta, miscelato ad argilla espansa, pomice, vetro espanso o altro scheletro di equivalenti caratteristiche e mantenuto in forma da un collante idrosolubile atossico. This modular element has a prismatic or trapezoidal shape in which the inclined side forms the front face and is made of compost or compost, mixed with expanded clay, pumice, expanded glass or other skeleton with equivalent characteristics and kept in shape by an adhesive. non-toxic water-soluble.
Forma oggetto della presente invenzione un elemento modulare per la realizzazione di rilevati secondo le caratteristiche della rivendicazione 1 . l e caratteristiche dell invenzione risulteranno più chiare dalla seguente descrizione di una forma di realizzazione esemplificativa fatta con riferimento alle allegate ligure in cui si rappresenta rispettivamente: The object of the present invention is a modular element for the construction of embankments according to the characteristics of claim 1. The characteristics of the invention will become clearer from the following description of an exemplary embodiment made with reference to the Ligurian annexes which respectively represent:
- nella figura 1 un elemento modulare secondo la presente invenzione in vista prospettica; - in figure 1 a modular element according to the present invention in perspective view;
- nella figura 2 una vista laterale dell elemento modulare di figura 1 ; - in figure 2 a side view of the modular element of figure 1;
- nelle figure 3a e 3b l<'>elemento modulare posto in opera per la realizzazione di uno strato di un rilevato: - in figures 3a and 3b the modular element installed for the construction of a layer of an embankment:
- nella figura 4 l elemento modulare utilizzato per la realizzazione di un rilevato a tre strati sovrapposti. - in figure 4 the modular element used for the construction of a three-layer embankment.
Con riferimento alle ligure menzionate, l elemento modulare comprende un blocco 2 sostanzialmente prismatico o trapezoidale avente una superficie inclinata 21. che in opera viene a costituire il paramento frontale del rilevato, una base 22, una superfìcie posteriore 23 sostanzialmente verticale ed una superfìcie superiore 24 sostanzialmente orizzontale. Il blocco viene realizzato tramite terricciato o compost, preferibilmente arricchito con concimanti, miscelato ad argilla espansa, pomice, vetro espanso o altro scheletro di equivalenti caratteristiche e mantenuto in lorma da un collante idrosolubile atossico. With reference to the Ligurians mentioned, the modular element comprises a substantially prismatic or trapezoidal block 2 having an inclined surface 21. which in place constitutes the front face of the embankment, a base 22, a rear surface 23 substantially vertical and an upper surface 24 substantially horizontal. The block is made using compost or compost, preferably enriched with fertilizers, mixed with expanded clay, pumice, expanded glass or other skeleton with equivalent characteristics and kept in shape by a non-toxic water-soluble glue.
Lì<'>inoltre presente un lembo di rete o di stuoia, vegetale e/o sintetica, fissata al blocco mediante incollatura, impunture od equivalente sistema di fissaggio. che riveste le superfìcie 21. 22 e 24, con la funzione di proteggere dall'erosione il blocco e di mantenere in posizione la semenza distribuita sulla faccia a vista 21. Questa è presente in quantità variabile a seconda del tipo di miscuglio impiegato e della zona geografica in cui si realizza l<'>opera d<'>arte. La superficie a vista inclinata presenta altresì uno o più solchi 25 disposti sostanzialmente in orizzontale, di varia profondità ed inclinati verso l<'>interno e verso la base del blocco, aventi funzione di raccogliere l<'>acqua piovana e di facilitarne l<'>infiltrazione entro la massa del blocco. Ciò al fine di immagazzinare l<'>acqua e renderla facilmente disponibile per l'irrigazione della copertura vegetale dopo la germinazione. Entro detti solchi sono presenti dei rinforzi 28 opportunamente distanziati l<'>uno dall<'>altro, aventi funzione di irrobustire il blocco in corrispondenza dei solchi che potrebbero rappresentare un punto di debolezza strutturale. Vantaggiosamente, la funzione di immagazzinamento dell’acqua piovana può essere facilitata dalla eventuale dispersione entro la massa del prisma di granuli di polimeri idro-rilentori (cristalli di sodio poliacri lato o simili ). There is also a strip of net or mat, vegetable and / or synthetic, fixed to the block by gluing, stitching or equivalent fastening system. which covers the surfaces 21. 22 and 24, with the function of protecting the block from erosion and keeping the seed distributed on the visible face 21 in position. This is present in variable quantities depending on the type of mixture used and the area geographic location in which the work of art is created. The inclined visible surface also has one or more grooves 25 arranged substantially horizontally, of varying depths and inclined towards the interior and towards the base of the block, having the function of collecting rainwater and facilitating its '> infiltration within the mass of the block. This is in order to store the water and make it readily available for irrigation of the vegetation cover after germination. Within said grooves there are reinforcements 28 suitably spaced one from the other, having the function of strengthening the block in correspondence with the grooves which could represent a structural weakness point. Advantageously, the rainwater storage function can be facilitated by the possible dispersion within the mass of the prism of hydro-reflective polymer granules (polyacrylate sodium crystals or the like).
Adatti collanti idrosolubili sono, ad esempio, i collanti polisaccaridi estratti dal legume di (ìuar o di Psyllium o i collanti polimerici acrilici biodegradabili e atossici. Suitable water-soluble adhesives are, for example, the polysaccharide adhesives extracted from the legume of (ìuar or Psyllium or the biodegradable and non-toxic acrylic polymeric adhesives.
La superfìcie inclinata 21 può avere una inclinazione rispetto a quella orizzontale compresa tra circa 45 e 80 gradi, preferibilmente tra 60 e 70 gradi. The inclined surface 21 can have an inclination with respect to the horizontal one comprised between about 45 and 80 degrees, preferably between 60 and 70 degrees.
La posa in opera dell<'>elemento modulare avviene seguendo le fasi illustrate nelle figure 3 a e 3h. The installation of the modular element takes place following the steps illustrated in figures 3 a and 3h.
Si dispongono i casseri a perdere in rete elettrosaldata secondo P allineamento previsto dal progetto. 1 casseri 26 sono gli stessi ricavati da fogli di rete elettrosaldata normalmente impiegati nella realizzazione delle terre rinforzate, con Punica avvertenza che la misura della loro base, in sezione, deve essere di almeno 30-40 CITI più larga della base 22 del blocco. 1 blocchi vengono posti in aderenza ai casseri 26. intervallati dai consueti tiranti impiegati per tenere in forma i casseri stessi. Viene, quindi, steso il rinforzo strutturale 27 (tipicamente una geogriglia) di lunghezza e resistenza conforme all'elaborato progettuale, in appoggio al blocco. Viene quindi posto il terreno di riempimento, che viene rullato a strati sottili in conformità con le prescrizioni progettuali dell<'>opera, fino a colmare lo spazio a tergo del blocco modulare e fino a raggiungere l<’>altezza, dopodiché la geogriglia 27 viene risvoltata sul piano del rilevato così ottenuto. The disposable formworks are arranged in electro-welded mesh according to the alignment foreseen by the project. The formworks 26 are the same obtained from electrowelded mesh sheets normally used in the construction of reinforced soils, with the only warning that the size of their base, in section, must be at least 30-40 CITI wider than the base 22 of the block. The blocks are placed in adherence to the formworks 26. interspersed with the usual tie rods used to keep the formworks in shape. The structural reinforcement 27 (typically a geogrid) of length and strength in accordance with the design elaboration is then spread, resting on the block. The filling soil is then placed, which is rolled in thin layers in accordance with the design requirements of the work, until the space behind the modular block is filled and the height is reached, after which the geogrid 27 it is turned upside down on the plane of the embankment thus obtained.
Si procede quindi, nello stesso modo, alla sovrapposizione degli altri elementi modulari secondo l'altezza necessaria come indicato in figura 4, in cui ciascuna porzione della base dell<'>elemento modulare 22 poggia sulla porzione della superficie superiore 24 dello strato sottostante in modo da generare un'unica superficie inclinata determinata dall<'>unione delle superflui inclinate 21 di ogni strato. The other modular elements are then superimposed in the same way according to the necessary height as indicated in Figure 4, in which each portion of the base of the modular element 22 rests on the portion of the upper surface 24 of the underlying layer so to generate a single inclined surface determined by the union of the superfluous inclines 21 of each layer.
11 trovato garantisce la presenza di un terreno di supporto per la vegetazione con composizione e qualità certificata ed evita difetti di riempimento in quanto il terreno all'interno del blocco è già pre -compattato. Esso costituisce, inoltre, una barriera ai raggi UV. proteggendo il rinforzo strutturale dall<'>azione di invecchiamento accelerato che si manifesterebbe nell area esposta sul paramento esterno e formando, inoltre, un cuscino che protegge il rinforzo strutturale da possibili danneggiamenti accidentali o vandalici, primo fra tutti quello causato da un eventuale incendio della scarpata. The invention guarantees the presence of a support soil for the vegetation with certified composition and quality and avoids filling defects since the soil inside the block is already pre-compacted. It also constitutes a barrier to UV rays. protecting the structural reinforcement from the accelerated aging action that would manifest itself in the exposed area on the external facing and also forming a cushion that protects the structural reinforcement from possible accidental or vandal damage, first of all that caused by a possible fire of the escarpment.
Il blocco è vantaggiosamente pre-seminato e arricchito con sostanze nutrienti, per cui non richiede interventi successivi di idrosemina. esso facilita e sveltisce inoltre le fasi di posa, eliminando fra l altro la compattazione con mezzi manuali della porzione di terreno che. diversamente, ricorrendo alla tecnica tino ad oggi usata, si troverebbe incuneata dietro la superfìcie inclinata del cassero in rete elettrosaldata. Detta operazione, in genere, costituisce la parte più gravosa e diffìcile della lavorazione, tenuto conto che la compattazione viene solitamente eseguita con un motocompattatore manuale, il cui uso richiede tempo e sforzo fìsico. The block is advantageously pre-sown and enriched with nutrients, so it does not require subsequent hydroseeding interventions. it also facilitates and speeds up the laying phases, eliminating, among other things, the compaction with manual means of the portion of land that. otherwise, using the vat technique used today, it would be wedged behind the inclined surface of the electro-welded mesh formwork. Said operation, in general, constitutes the most onerous and difficult part of the working, considering that the compaction is usually carried out with a manual motor compactor, the use of which requires time and physical effort.
