Takulandilani ku CHUANGRONG

In maofesi apansi panthaka, njira yamapaipi yokwiriridwa kwanthawi yayitali ndi yosafikirika komanso yosaoneka.Nthawi zonse mavuto monga kupunduka ndi kutayikira kumachitika, ndikofunikira kuti "atsegulidwe" kuti afukulidwe ndi kukonzedwa, zomwe zimabweretsa zovuta zazikulu pamoyo wa nzika.Zotsatira zake, ukadaulo wa pipeline trenchless unapezeka.

Ukadaulo wosafukula wa payipi umatchedwa "njira yocheperako" ya mzindawo.Ndi njira yomanga yotetezeka komanso yothandiza poteteza chilengedwe.Imatha kukonza mwachangu komanso moyenera mbali zingapo zapaipi nthawi imodzi popanda kukumba kangapo., Kukonza, kutayirapo.

Ukadaulo wapaipi wopanda waya wapanga chitoliro chopanda madzi cha HDPE cholimba, chomwe chili choyenera madera omwe ntchito zokumba sizingachitike ndikukwaniritsa zofunikira zakusintha kwapaipi kwamakono kwapaipi.

Imagwiritsa ntchito polyethylene yolimba kwambiri ngati zida zopangira ndipo imapangidwa ndi kutulutsa ndi vacuum sizing.Makoma amkati ndi akunja ndi osalala komanso athyathyathya.Sikuti ndi ochezeka zachilengedwe, komanso kwambiri kupsinjika akulimbana kukana, mankhwala kukana, otsika kutentha kwambiri kukana, etc. Iwo ali ndi makhalidwe a ukalamba kukana ndipo ali ndi moyo kwa zaka 50, amene amachepetsa kwambiri chiwerengero cha payipi. kukonzanso ndi kukonzanso, ndikuwongolera moyenera ndalama zoyendetsera ntchito ndi kukonza.

Chimodzi mwazabwino za mapaipi a HDPE osasunthika osasunthika ndi mawonekedwe osiyanasiyana.Mtunduwu umachokera ku dn160-dn800, ndipo kuuma kwa mphete ndi SN8, SN16, ndi SN32, zomwe zimatha kukwaniritsa zofunikira zaumisiri kwambiri.Panthawi imodzimodziyo, kugwirizanitsa kwake kotetezeka komanso kodalirika kumapangitsa kuti ntchito yomanga ikhale yosavuta komanso yosavuta.

Poganizira kuti zisawononge malo a m'matauni, osakhudza kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka anthu.Limbikitsani zotsatira za zomangamanga zamatawuni ndikupangitsa mzindawu kukhala wosatsekeka.
