Izinzuzo kanye nomlando wokulungiswa kwe-CIPPiphayiphi

Indlela yokuphenyisa ye-CIPP (elashwe endaweni) inezinzuzo ezilandelayo:

(1) Isikhathi sokwakha esifushane: Kuthatha cishe usuku olungu-1 kuphela kusukela ekucutshungulweni kwempahla yolayini kuya ekulungisweni, ekuguqulweni kwentengo, ekushisiseni, nasekulungisweni kwendawo yokwakha.

(2) Izinto zokusebenza zithatha indawo encane: ama-boilers amancane kuphela namaphampu ajikelezayo amanzi ashisayo adingekayo, futhi indawo yomgwaqo ayibalulekile ngesikhathi sokwakhiwa, umsindo uphansi, futhi umthelela wezimoto zomgwaqo mncane.

(3) Ipayipi le-lining lihlala isikhathi eside futhi liyasebenza: ipayipi yocingo inezinzuzo zokumelana nokugqwala futhi igqoka ukumelana.Impahla inhle, futhi ingaxazulula ngokuphelele inkinga yokungena kwamanzi angaphansi komhlaba kanye unomphela.Ipayipi linokulahlekelwa okuncane kwezingxenye eziphambanayo, indawo ebushelelezi, kanye nokushayisana kwamanzi okuncishisiwe (i-coefficient ye-friction yehlisiwe isuka ku-0.013 iye ku-0.010), okuthuthukisa umthamo wokugeleza wepayipi.

(4) alondoloze imvelo futhi alondoloze izinsiza: akukho mgwaqo ombiwayo, akukho udoti, akukho siminyaminya.

Indlela yokuguqula i-CIPP yasungulwa e-United Kingdom ngeminyaka yawo-1970s yase iqala ukusetshenziswa eYurophu nase-United States.Ngo-1983, isikhungo socwaningo lwamanzi saseBrithani i-WRC (isikhungo socwaningo lwamanzi) sakhipha izindinganiso zobuchwepheshe zokulungisa ngaphandle kwegatsha nokuvuselela amapayipi angaphansi komhlaba engxenyeni engenhla yomhlaba.

Isikhungo Sikazwelonke Sokuhlola Izinto Ezisetshenziswayo sase-United States sakha futhi samemezela ukucaciswa kobuchwepheshe bokwakha kokulungisa amapayipi angenagatsha kanye nokucaciswa kwe-atm kokuklanywa kwesakhiwo ngo-1988, okuwukuklanywa nokuphathwa kokwakhiwa kobuchwepheshe.Kusukela ngeminyaka yawo-1990s, ubuchwepheshe be-CIPP sebusetshenziswe kabanzi emhlabeni wonke ngenxa yentengo ephansi kanye nomthelela omncane kuthrafikhi.Thatha iJapane njengesibonelo.Phakathi kwamapayipi acishe abe yi-1,500 amakhilomitha alungiswe kusetshenziswa ubuchwepheshe obungenagatsha kusukela ngo-1990, ngaphezu kwama-85% obude sebebonke alungiswa kusetshenziswa ubuchwepheshe be-CIPP.Ubuchwepheshe bendlela yokugumbuqela ye-CIPP buvuthwe kakhulu.Izinto ezibonakalayo kufanele zinikezwe ukunakwa okuphezulu uma sisebenzisa ipayipi lensimbi ukuze sinikeze amanzi.Kungakhathaliseki ukuthi uthenga ipayipi lensimbi elingenamthungo noma i-ERW, kufanele uhlole ukuthi impahla yasekuqaleni yenzelwe ipayipi lensimbi.
