Umsele
Imimiselo yesizwe neyengingqi kunye nezikhokelo zomhlaba ogqunyiweyoImibhobho ye-PEkufuneka zilandelwe ngexesha lokwakhiwa komsele oyimfuneko. Umsele kufuneka uvumele zonke iindawo zombhobho ukuba zibe kubunzulu obukhuselekileyo kwiqabaka kunye nobubanzi obaneleyo.
Ububanzi bomsele
Ukuqwalasela iprojekthi kunye nesiphumo esongezelelweyo kwimibhobho evela emhlabeni, ububanzi bomsele kufuneka bube buncinci kangangoko.
Uluhlu olucetyiswayo lobubanzi bomsele. La maxabiso ahambelana nemigaqo yokuba ububanzi bomjelo mabubemxinwa kangangoko ukuze kuncitshiswe imithwalo yangaphandle kunye neendleko zofakelo, ngeli lixa kunikwa indawo eyaneleyo yokubonelela ngoxinaniso oluchaziweyo.
Obona bubanzi bomsele obamkelweyo buya kuphenjelelwa ziimeko zomhlaba, iinkqubo zokudityaniswa, kunye nokuba amakhonkco enziwa kumsele.
A Ububanzi bomsele ocetyiswayo
| dn yeImibhobho ye-PE(mm) | Ububanzi bomsele (mm) |
| 20-63 | 150 |
| 75-110 | 250 |
| 12~315 | 500 |
| 355~500 | 700 |

| 800~1000 | 1200 |
AphoImibhobho ye-PEzifakwe kunye nezinye iinkonzo kwiimeko eziqhelekileyo zomsele, ububanzi bomsele bunokuthi buchazwe yimimiselo yabasemagunyeni ukuze kuvumeleke imisebenzi yokulondoloza kamva.
Ubunzulu bomsele
Apho iImibhobho ye-PEumgca webakala awuchazwanga, isigqubuthelo esingaphezulu kweepayipi ze-PE kufuneka zibekwe ukwenzela ukuba ukhuseleko olwaneleyo kwimithwalo yangaphandle, umonakalo wesithathu, kunye ne-traffic traffic inikwe.
Apho kunokwenzeka, imibhobho kufuneka ifakwe phantsi kweemeko zobunzulu obuncinane kwaye, njengesikhokelo, amaxabiso adweliswe apha ngezantsi kufuneka amkelwe.

UFakelo loMgangatho oPhezulu
Imibhobho ye-CHHUANGRONG PE inokufakwa ngaphezulu komhlaba ukwenzela uxinzelelo kunye nezicelo ezingenaxinzelelo kuzo zombini ukuvezwa ngokuthe ngqo kunye neemeko ezikhuselweyo. Imibhobho ye-PE emnyama ingasetyenziswa kwiimeko zokubeka ilanga ngokuthe ngqo ngaphandle kokhuseleko olongezelelweyo. Apho imibhobho ye-PE yemibala ngaphandle komnyama isetyenziswe kwiimeko ezibonakalayo, ngoko ke imibhobho kufuneka ikhuselwe ekukhanyeni kwelanga. Apho imibhobho ye-PE ifakwe kwiimeko zokuvezwa ngokuthe ngqo, ngoko ke ukunyuka kweqondo lokushisa kwe-PE ngenxa yokuvezwa kufuneka kuthathelwe ingqalelo ekusekeni ukulinganiswa koxinzelelo lokusebenza kwimibhobho ye-PE. Ubushushu bendawo buyakha iimeko ezifana nokuba kufutshane nemigca yomphunga, iiradiyetha, okanye izixa zokukhupha umoya kufuneka ziphetshwe ngaphandle kokuba imibhobho ye-PE ikhuselwe ngokufanelekileyo. Apho kusetyenziswa izinto ezibambekayo, ezi kufuneka zilungele izicelo zokuvezwa.
Izinto zokulala kunye nokugcwaliswa ngasemva
Imigangatho yemisele egrunjiweyo kufuneka ilungiswe ngokulinganayo, kwaye ikhululeke kuwo onke amatye, kunye nezinto eziqinileyo. Izinto zokulala ezisetyenziswa kwimisele yomibini kunye ne-evenments iya kuba yenye yezi zilandelayo:
1. Isanti okanye umhlaba, ongenamatye angaphezu kwe-15 mm, kunye nawo nawaphi na amagaqa odongwe oluqinileyo angaphezu kwe-75 mm ngobukhulu.
2. Ilitye eliqhekeziweyo, igrabile, okanye imathiriyeli ehleliweyo enomlinganiselo ophakamileyo we-15 mm.
3.Izinto ezigrunjiweyo ezingenamatye okanye imifuno.
4. Izigaqa zodongwe ezinokucuthwa zibe ngaphantsi kwe-75 mm ngobukhulu.
Kuninzi lwezicelo zemibhobho ye-PE, ubuncinci be-75mm yemathiriyeli yokulala isetyenziswa kwimisele yomibini kunye ne-emalinge ekugrunjweni komhlaba. Xa kugrunjwa ematyeni, kungafuneka ubunzulu bomandlalo obuyi-150 mm.
Intsalela yomsele, okanye ukugcwaliswa kodonga kunokwenziwa ngezinto zemveli ebezigrunjwe ngaphambili.
Ezi kufuneka zingabi namatye amakhulu, izinto zemifuno, kunye nezixhobo ezingcolisekileyo, kwaye zonke izinto kufuneka zibe nobukhulu beqhekeza elingaphantsi kwe-75 mm.
Apho iipayipi ze-PE zifakwe kwiindawo ezinemithwalo ephezulu yangaphandle, ngoko ke izinto zokuzalisa umva kufuneka zibe kumgangatho ofanayo kunye nempahla yokulala kunye neyongezelelweyo.
Iibhloko ze-Thrust kunye noThintelo lwemibhobho
Iibhloko ze-Thrust ziyafuneka kwimibhobho ye-CHUANGRONG PE kwizicelo zoxinzelelo apho amajoyina angaxhathisi imithwalo ye-longitudinal. Iibhlokhi ze-thrust kufuneka zinikwe kulo lonke utshintsho kwicala.
Apho kusetyenziswe iibhloko zekhonkrithi, iindawo zoqhagamshelwano phakathi kombhobho we-PE, okanye ukudibanisa kunye nebhloko yokutyhala kufuneka zikhuselwe ukuthintela ukukrazuka kwe-PE. Irabha okanye i-malthoid sheeting ingasetyenziselwa le njongo.
Zonke izinto zokufakelwa kunye nezinto ezinzima ezifana neevalve zentsimbi etyhidiweyo kufuneka zixhaswe ukwenzela ukuthintela ukulayishwa kwamanqaku kwizinto ze-PE. Ukongezelela, apho i-valve isetyenzisiweyo, imithwalo ye-torque evela kwimisebenzi yokuvula / yokuvala kufuneka ixhathise ngeenkxaso zebhloko.
Ukujikwa kweMibhobho ye-PE
Yonke imibhobho ye-PE efakwe kulungelelwaniso olugobileyo kufuneka izotywe ngokulinganayo kulo lonke ubude begophe, kwaye ingabi ngaphezu kwecandelo elifutshane. Oku kunokukhokelela kwi-kinking kwi-diameter encinci, kunye / okanye imibhobho yodonga oluncinci.
Imibhobho ye-PE edayamitha emikhulu (engama-450mm nangaphezulu) kufuneka idityaniswe kunye, emva koko izotywe ngokulinganayo kwiradiyasi oyifunayo. Ubuncinane obuvumelekileyo berediyasi yokugoba yombhobho weHDPE unokufunyanwa.
I-Relining & Non-dig Trench
Imibhobho ekhoyo ingalungiswa ngokufaka i-CHUANGRONG PE imibhobho kwimibhobho emidala. Imibhobho yokufaka inokutsalwa kwindawo yayo ngeefestile zomatshini. Ukudibanisa kunye nemibhobho ye-PE kubonelela ngesakhiwo esikwaziyo ukumelana noxinzelelo lwangaphakathi okanye ukulayishwa kwangaphandle ngaphandle kokuxhomekeka kumandla ashiyekileyo ezinto zokuqala zemibhobho eyonakeleyo.
Imibhobho ye-PE ifuna indawo yokungena nobude obufutshane obufutshane ukulungiselela iradiyasi yombhobho we-PE ukukhokelela kumbhobho osele ukho, kunye nokudityaniswa kwefestile esetyenziselwa ukutsala iliner yePE ecaleni kombhobho. Ubuncinci berediyasi yokugoba ye-PE liner ingabalwa njengoko kuchaziwe phantsi kwePipeline Curvature yencwadana.
Imibhobho ye-PE isenokusetyenziswa kwiiprojekthi zomsele ezingezizo ezembiwayo, ezinje ngoKwila iHorizontal Directional Drilling (HDD). Olunye usetyenziso lwakuqala lombhobho we-PE odayamitha omkhulu ekugrunjweni okuya ngakuye yayiyeyokuwela imilambo. Umbhobho we-PE ulungele olu fakelo ngenxa yokunyamezela kwawo umkrwelo kunye nenkqubo yokudibanisa edityanisiweyo enika umdibaniso ovuzayo we-zero kunye nomthamo we-tensile uyilo olingana naleyo yombhobho.
Ukuza kuthi ga ngoku, oomatshini ababonisa indlela bafakele umbhobho we-PE wegesi, amanzi, kunye nemibhobho ehambisa amanzi amdaka; imijelo yonxibelelwano; kunye neentlobo zemigca yeekhemikhali.
Ezi projekthi zazibandakanya kungekuphela nje ukuwela imilambo kodwa kwanokuwela uhola wendlela neendlela ezilungelelanisiweyo kwiindawo eziphuculweyo ukuze zingaphazamisi izitrato, iindlela zokuhamba neendawo zokungena ezoshishino.
Ukulungisa kunye noLondolozo
Ngokomonakalo ohlukeneyo, kukho iintlobo zokulungisa iteknoloji ukukhetha. Ukulungiswa kunokufezekiswa kumbhobho omncinci onqumlayo ngokuvula isithuba esaneleyo somsele kunye nokusikwa kwesiphene. Faka indawo yecandelo elonakeleyo kunye necandelo elitsha lombhobho.
Ukulungisa umbhobho omkhulu wedayamitha unokufezekiswa ngeqhekeza le-spool eline-flanged. Icandelo elonakeleyo liyasuswa.Okulandelayo, umatshini wokudityaniswa kwempundu wehliswa kumsele.Uqhagamshelo oluFlanged ludityaniswe kwindawo nganye evulekileyo, kwaye indibano ye-spool ene-flanged ibotshelelwe endaweni. I-spool ene-flanged kufuneka yenziwe ngokuchanekileyo ukuze ilingane isithuba esisiphumo sombhobho.
