b) načrtovanje obnove cevovoda;
– informacije o operativnih dejavnostih in povezane zahteve:
c) specifikacija projekta;
d) uporaba tehnik;
e) dokumentacija postopka načrtovanja in uporabe.
Podane so definicije in klasifikacija družin tehnik za obnovo in zamenjavo brez izkopa
ter opisane so njihove ustrezne značilnosti. Področja uporabe zajemajo podzemna
omrežja za odvodnjavanje in kanalizacijo ter podzemna omrežja za oskrbo z vodo in s plinom.
Naslednji vidiki ne spadajo na področje uporabe tega dokumenta:
– nova gradnja v okviru razširitev omrežja;
– računske metode za določanje (za vsako izvedljivo tehniko) značilnosti oblog ali
nadomestnega materiala za cevi, ki je potreben za zagotovitev želene učinkovitosti obnovljenega cevovoda;
– tehnike, ki zagotavljajo nekonstrukcijske obloge cevi pod tlakom;
– tehnike za lokalna popravila.
Načrtovalec je odgovoren za izbiro in načrtovanje sistema za obnovo ali zamenjavo cevovodov
brez izkopa.
