Zvakanakira uye nhoroondo yeCIPP kugadzirisapipeline

Iyo CIPP yekupuruzira nzira (yakarapwa munzvimbo pombi) ine zvinotevera zvakanakira:

(1) Nguva pfupi yekuvaka: Zvinongotora rinenge zuva rimwe chete kubva pakugadziriswa kwesimbi kusvika pakugadzirira, kushandura, kupisa, uye kurapa kwenzvimbo yekuvaka.

(2) Midziyo inotora nzvimbo diki: mabhoiler madiki chete uye mvura inopisa inotenderera pombi inodiwa, uye nzvimbo yemugwagwa haina kukosha panguva yekuvaka, ruzha rwakaderera, uye kukanganisa kwemigwagwa kudiki.

(3) Pombi yekugadzira inogara yakasimba uye inoshanda: pombi yembambo ine zvakanakira kushora uye inopfeka kuramba.Nyaya yacho yakanaka, uye inogona kugadzirisa zvachose dambudziko rekupinda kwemvura yepasi kamwechete kwenguva dzose.Iyo pombi ine zvishoma muchinjika-chikamu kurasikirwa kwenzvimbo, nzvimbo yakatsetseka, uye yakaderedzwa kukwesha kwemvura (iyo friction coefficient yakaderedzwa kubva 0.013 kusvika 0.010), iyo inovandudza kuyerera kwepombi.

(4) chengetedza mhoteredzo uye chengetedza zviwanikwa: hapana kucherwa kwemigwagwa, hapana marara, hapana kujairika kwemotokari.

Iyo CIPP inversion tekinoroji yakagadzirwa kuUnited Kingdom kuma1970s ichibva yatanga kushandiswa muEurope nekuUnited States.Muna 1983, nzvimbo yekutsvagisa mvura yeBritish WRC (nzvimbo yekutsvagisa mvura) yakapa zviyero zvehunyanzvi zvekugadzirisa zvisina bazi uye kuvandudzwa kwemapaipi epasi pevhu munzvimbo yepamusoro yepasi.

National Materials Testing Center yeUnited States yakagadzira uye yakashambadza hunyanzvi hwekuvaka hwekugadziriswa kwepombi isina bazi uye iyo atm yakatarwa yedhizaini yedhizaini muna 1988, iyo dhizaini uye manejimendi ekuvaka kwehunyanzvi.Kutanga kuma1990s, tekinoroji yeCIPP yakashandiswa zvakanyanya pasi rese nekuda kwemutengo wayo wakaderera uye kushomeka kunokanganisa traffic.Tora Japan somuenzaniso.Pakati pemakiromita angangoita 1,500 emapaipi akagadziriswa pachishandiswa tekinoroji isina bazi kubvira 1990, inodarika 85% yehurefu hwacho yakagadziriswa pachishandiswa tekinoroji yeCIPP.Iyo tekinoroji yeCIPP yekupidigura nzira yakakura kwazvo.Zvishandiso zvinofanirwa kupihwa zvakanyanya kana tikashandisa pombi yesimbi yekupa mvura.Hazvina mhosva kuti unotenga pombi isina musono kana ERW simbi, unofanira kutarisa kuti zvinhu zvepakutanga zvakagadzirirwa pombi yesimbi.
