M'zaka khumi zapitazi, kufunikira kogwiritsa ntchito mphamvu moyenera, kuchepetsa kuwononga chilengedwe, kuchepetsa kuchuluka kwa ngozi zopanga chitetezo, ndikuwonetsetsa kuti chitetezo chamoyo chikuchulukirachulukira.Kupanga ndi kukhazikitsa ndondomeko ndi njira zotetezera chilengedwe kwakhala cholinga chachikulu cha ntchito zothandizira anthu.Chifukwa cha zovuta zosiyanasiyana zakupukuta mabomba, mapangidwe osiyanasiyana, ndi mikhalidwe yosiyanasiyana yogwiritsira ntchito, ngati ma hoses akugwiritsidwa ntchito moyenera molingana ndi ndondomekoyi, sizidzangochepetsa mwayi wa mavuto, kuwonjezera moyo wautumiki wa hoses, komanso kuchepetsa ndalama zogwirira ntchito.
Malangizo ogwiritsira ntchito payipi ya dredging:
Paipi yopopera imatha kugwiritsidwa ntchito kuwonetsa zinthu zomwe zatchulidwa, apo ayi zitha kuwononga payipi kapena kuchepetsa moyo wake wautumiki..
Paipi yopukutira siyenera kugwiritsidwa ntchito mopanikizika (kuphatikiza kukakamiza) kupitilira kukakamiza kogwirira ntchito.
Nthawi zambiri, kutentha kwa zinthu zomwe zimaperekedwa ndi payipi yowotchera sikuyenera kupitirira -20 ° C-+50 ° C, apo ayi moyo wautumiki wa payipi udzachepetsedwa.
Paipi yopukutira siyenera kugwiritsidwa ntchito pansi pa torsion.
Paipi yobowoleza iyenera kusamaliridwa mosamala, sayenera kukokera pamalo akuthwa komanso ovuta, sayenera kupindika ndikuphwanyidwa.
Paipi yopoperayo iyenera kukhala yaukhondo ndipo mkati mwake iyenera kuthamangitsidwa kuti zinthu zakunja zisalowe mu payipi, kulepheretsa kutumiza madzimadzi, ndikuwononga payipi.
CDSR ili ndi zaka zopitilira 40 pakufufuza, chitukuko ndi kupanga payipi ya rabara.Paipi yopangira makonda yopangidwa ndi CDSR yakhala ikugwiritsidwa ntchito padziko lonse lapansi ndipo yalimbana ndi mayeso pama projekiti osiyanasiyana.Kukwaniritsa zosowa zamakasitomala ndi imodzi mwantchito zathu zofunika kwambiri, ndipo akatswiri athu adzakupatsani yankho labwino kwambiri potengera magawo osiyanasiyana a projekiti yowononga.
