In the case of overlapping microducts, a component called a fender is often used, consisting of a certain number of overlapping microducts (usually 7) held together by a plastic sheath.<\/p>\n\n\n\n<p>La profondit\u00e0 della microtrincea dipende dal numero di microduct e dal contesto in cui la microtrincea \u00e8 realizzata.<\/p>\n\n\n\n<p>In ambienti periferici, dove l&#8217;utilizzo della microtrincea \u00e8 quello di consentire il collegamento dell&#8217;abbonato al pi\u00f9 vicino punto di accesso alla rete, la microtrincea assume l&#8217;attributo &#8220;delivery&#8221; (nel senso che che serve a &#8220;consegnare&#8221; la&#8217;vccesso in fibra ottica ad un utente terminale). In questo caso si utilizza un solo microduct e la profondit\u00e0 di scavo \u00e8 di 15\/20 cm.<\/p>\n\n\n\n<p>Quando l&#8217;obiettivo \u00e8 di ospitare una pluralit\u00e0 di cavi ottici per medie\/lunghe distanze, ad esempio lungo una strada, si parla di microtrincea &#8220;creation&#8221;.<\/p>\n\n\n\n<p>La microtrincea creation ha profondit\u00e0 tipiche di 30 cm, talvolta 35, utili a mantenere un sufficiente estradosso anche in caso di posizionamento di un fender.<\/p>\n\n\n\n<p>The restoration of the micro-trench is done by filling the excavation with suitable mortars, usually without resurfacing.<\/p>\n<\/div>\n<\/div><\/div>\n\n\n\n<div id=\"wp-block-themeisle-blocks-advanced-columns-f4c3463d\" class=\"wp-block-themeisle-blocks-advanced-columns has-2-columns has-desktop-twoOne-layout has-tablet-equal-layout has-mobile-collapsedRows-layout has-vertical-unset\"><div class=\"wp-block-themeisle-blocks-advanced-columns-overlay\"><\/div><div class=\"innerblocks-wrap\">\n<div id=\"wp-block-themeisle-blocks-advanced-column-06966a83\" class=\"wp-block-themeisle-blocks-advanced-column\">\n<p>There are generally two techniques for creating a micro trench.<\/p>\n\n\n\n<p>La prima, comunemente ed ampiamente utilizzata nella minitrincea (con larghezze di scavo di 10 cm circa) fa uso di una ruota provvista di denti in vidia, azionata idraulicamente da una monopala. L&#8217;utilizzo di questa attrezzatura per la microtrincea (molto pi\u00f9 stretta della minitrincea) pone problemi di qualit\u00e0 dello scavo, che raramente si presenta preciso in larghezza, proprio a causa del sistema adottato (a &#8220;percussione&#8221;). Ne consegue, tra l&#8217;altro, un notevole aumento del materiale di ripristino, con aumento dei costi. Inoltre, questa tecnologia costruttiva produce una quantit\u00e0 notevole di polvere, poich\u00e8 la ruota dentata lavora a secco.<\/p>\n\n\n\n<p>La seconda, adottata dalle soluzioni proposte da Rertech, si basa sull&#8217;uso di un utensile circolare &#8211; detto &#8220;mola&#8221; &#8211; caratterizzato da una serie di segmenti realizzati con un conglomerato basato su diamante ed altri materiali duri e disposti per saldobrasatura sulla circonferenza dell&#8217;utensile. La larghezza dei segmenti \u00e8 pari alla larghezza della microtrincea da realizzare.<\/p>\n\n\n\n<p>L&#8217;utensile diamantato \u00e8 montato su macchine specifiche, derivate &#8211; come principio &#8211; dalle classiche tagliasfalto, e dotate di un propulsore a scoppio, benzina o diesel.<\/p>\n\n\n\n<p>La qualit\u00e0 del taglio ottenuto con le mole diamantate, che operano sostanzialmente una fresatura del manto stradale, \u00e8 tale che la microtrincea al termine della lavorazione si presenta come un taglio preciso e qualitativamente ineccepibile. <\/p>\n\n\n\n<p>Le mole diamantate lavorano in ambiente umido, raffreddate da un flusso di acqua distribuito dalla macchina durante la lavorazione. Ne consegue l&#8217;assenza di polvere e, nei modelli pi\u00f9 performanti, anche l&#8217;assenza di fango, sostituito dal materiale di risulta umido e collocato ai lati dello scavo.<\/p>\n<\/div>\n\n\n\n<div id=\"wp-block-themeisle-blocks-advanced-column-a024e6fa\" class=\"wp-block-themeisle-blocks-advanced-column\">\n<figure class=\"wp-block-image size-full\"><img
