Ubwino ndi mbiri ya kukonza CIPPpayipi

Njira yopunthira ya CIPP (yochiritsidwa m'malo mwake) ili ndi izi:

(1) Nthawi yachidule yomanga: Zimangotenga tsiku limodzi kuchokera pakukonza zomangira mpaka pokonza, kubweza, kutenthetsa, ndi kuchiritsa malo omangawo.

(2) Zidazi zimakhala ndi malo ang'onoang'ono: ma boilers ang'onoang'ono okha ndi mapampu ozungulira amadzi otentha omwe amafunikira, ndipo dera la msewu ndi lochepa kwambiri pomanga, phokoso limakhala lochepa, ndipo zotsatira za magalimoto pamsewu ndizochepa.

(3) Chitoliro chachitsulo chimakhala chokhazikika komanso chothandiza: chitoliro chachitsulo chimakhala ndi ubwino wa kukana kwa dzimbiri ndipo chimavala kukana.Zinthuzi ndi zabwino, ndipo zimatha kuthetsa vuto la kulowa pansi pamadzi kamodzi kokha.Mapaipi amakhala ndi kutayika pang'ono kwa magawo, malo osalala, komanso kukangana kwamadzi komwe kumachepetsedwa (kugunda kwapakati kumachepetsedwa kuchoka pa 0.013 mpaka 0.010), zomwe zimapangitsa kuti payipi iyende bwino.

(4) sungani chilengedwe ndi kusunga chuma: palibe kukumba misewu, palibe zinyalala, palibe kupanikizana kwa magalimoto.

Njira yosinthira CIPP idapangidwa ku United Kingdom m'zaka za m'ma 1970 ndipo idayamba kugwiritsidwa ntchito ku Europe ndi United States.Mu 1983, malo ofufuza zamadzi aku Britain WRC (malo ofufuza zamadzi) adapereka miyezo yaukadaulo yokonza popanda nthambi ndikukonzanso mapaipi apansi panthaka kumtunda kwa dziko lapansi.

National Materials Testing Center yaku United States idapanga ndikulengeza zaukadaulo waukadaulo wokonza mapaipi opanda nthambi komanso ma atm opangira kamangidwe kake mu 1988, komwe kamangidwe ndi kasamalidwe kaukadaulo.Kuyambira m'zaka za m'ma 1990, teknoloji ya CIPP yakhala ikugwiritsidwa ntchito kwambiri padziko lonse lapansi chifukwa cha mtengo wake wotsika komanso kuchepa kwa magalimoto.Chitsanzo cha Japan.Pakati pa mapaipi pafupifupi makilomita 1,500 omwe akonzedwa pogwiritsa ntchito luso lamakono lopanda nthambi kuyambira 1990, oposa 85% a kutalika kwake akonzedwa pogwiritsa ntchito luso la CIPP.Ukadaulo wa njira yogubuduza CIPP ndi yokhwima kwambiri.Zida ziyenera kuperekedwa chidwi kwambiri ngati tigwiritsa ntchito chitoliro chachitsulo popereka madzi.Ziribe kanthu kuti mutagula chitoliro chachitsulo chosasunthika kapena cha ERW, muyenera kuyang'ana kuti choyambiriracho chapangidwira chitoliro chachitsulo.
