Umsele
Imithetho kazwelonke neyesifunda neziqondiso zomhlabathi omboziweAmapayipi e-PEkufanele zilandelwe ngesikhathi kwakhiwa umsele odingekayo. Umsele kufanele uvumele zonke izingxenye zepayipi ukuba zibe ekujuleni okuvikelekile kuqhwa kanye nobubanzi obanele.
Ububanzi bomsele
Uma kucatshangelwa iphrojekthi kanye nomthelela owengeziwe kumapayipi asuka emhlabeni, ububanzi bomsele kufanele bube buncane ngangokunokwenzeka.
A uhlu olunconyiwe lobubanzi bomsele. Lawa manani ahambisana nezimiso zokuthi ububanzi bomsele kufanele bube buncane ngangokunokwenzeka ukuze kuncishiswe imithwalo yangaphandle nezindleko zokuwufaka, kuyilapho kunikwa isikhala esanele sokuhlinzeka ukuminyana okucacisiwe.
Ububanzi bangempela bomsele obamukelwayo buyothonywa izimo zenhlabathi, izinhlelo zokuhlanganisa, kanye nokuthi amalunga enziwa yini emseleni.
Ububanzi bomsele obunconyiwe
| dn kweAmapayipi e-PE(mm) | Ububanzi bomsele (mm) |
| 20-63 | 150 |
| 75~110 | 250 |
| 12~315 | 500 |
| 355-500 | 700 |
| 560~710 | 910 |
| 800~1000 | 1200 |
KuphiAmapayipi e-PEafakwe nezinye izinsiza ezimweni ezivamile zomsele, ububanzi bomsele bungacaciswa yimithetho yomkhandlu wendawo ukuze kuvunyelwe imisebenzi yokulungisa kamuva.
Ukujula komsele
Lapho iAmapayipi e-PEumugqa webanga awucacisiwe, ikhava engaphezulu kwamapayipi e-PE idinga ukumiswa ukuze kuhlinzekwe ukuvikeleka okwanele emithwalweni yangaphandle, ukulimala komuntu wesithathu, kanye nethrafikhi yokwakha.
Lapho kungenzeka khona, amapayipi kufanele afakwe ngaphansi kwezimo zokujula okungenani futhi, njengomhlahlandlela, amanani abhalwe ngezansi kufanele amukelwe.

Ngaphezulu kokufakwa kweGround
Amapayipi e-CHHUANGRONG PE angase afakwe ngaphezu komhlabathi ukuze afake izicelo zokucindezela nokungacindezeli kukho kokubili ukuchayeka okuqondile nezimo ezivikelekile. Amapayipi e-PE amnyama angasetshenziswa ezimeni zokuchayeka elangeni ngaphandle kokuvikeleka okwengeziwe. Lapho amapayipi e-PE emibala ngaphandle kokumnyama asetshenziswa ezimweni eziveziwe, khona-ke amapayipi adinga ukuvikelwa ekukhanyeni kwelanga. Lapho amapayipi e-PE efakwe ezimweni zokuchayeka okuqondile, khona-ke izinga lokushisa lempahla ye-PE elikhuphukile ngenxa yokuchayeka kufanele licatshangelwe ekusunguleni isilinganiso sokucindezela kokusebenza kwamapayipi e-PE. Izimo zokushisa zasendaweni ezifana nokuba seduze kwezintambo zesitimu, ama-radiator, noma izitaki zokukhipha umoya kufanele zigwenywe ngaphandle kwalapho amapayipi e-PE evikelwe ngokufanelekile. Lapho kusetshenziswa khona izinto ezibambekayo, lezi kufanele zifanelekele izinhlelo zokusebenza zokuchayeka.
Izinto Zokulala Nokugcwaliswa Kwasemuva
Izitezi ezimbiwe zemisele kufanele zisikwe ngokulinganayo, futhi zikhululeke kuwo wonke amatshe, nezinto eziqinile. Izinto zokulala ezisetshenziswa kuyo yomibili imisele kanye nama-envelope kuzoba okunye kwalokhu okulandelayo:
1. Isihlabathi noma inhlabathi, engenawo amatshe angaphezu kuka-15 mm, nanoma yiziphi izigaxa zobumba eziqinile ezingaphezu kuka-75 mm ngosayizi.
2. Itshe elichotshoziwe, amatshe, noma izinto ezihleliwe zokugreda ezinobukhulu obungu-15 mm.
3.Impahla embiwe engenawo amatshe noma imifino.
4. Izigaxa zobumba ezingancishiswa zibe ngaphansi kuka-75 mm ngosayizi.
Eziningi zezicelo zamapayipi e-PE, ubuncane obungama-75mm bezinto zokulala busetshenziswa kuyo yomibili imisele nasemagqumeni lapho kumbiwa inhlabathi. Ukuze kumbiwe edwaleni, kungase kudingeke ukujula kwendawo yokulala engu-150 mm.
Okusele komsele, noma ukugcwaliswa konqenqema kungenziwa ngezinto zomdabu ezambiwa ngaphambilini.
Lezi kufanele zingabi namatshe amakhulu, imifino, nezinto ezingcolile, futhi zonke izinto kufanele zibe nobukhulu bezinhlayiyana ezingaphansi kuka-75 mm.
Lapho amapayipi e-PE efakwe ezindaweni ezinemithwalo ephezulu yangaphandle, izinto zokugcwalisa ngemuva kufanele zibe sezingeni elifanayo nelezinto zokulala nezinto zokumbondelana.
Ama-Trust Blocks & I-Pipe Restraint
Ama-thrust blocks ayadingeka kumapayipi e-CHUANGRONG PE ekufakweni kwengcindezi lapho amalunga engamelani nemithwalo ye-longitudinal. Ama-thrust blocks kufanele anikezwe kuzo zonke izinguquko lapho uya khona.
Lapho kusetshenziswa khona amabhlogo kakhonkolo, izindawo zokuthintana phakathi kwepayipi le-PE, noma i-fitting kanye ne-thrust block kufanele zivikelwe ukuze kuvinjelwe ukuhuzuka kwe-PE. Irabha noma i-malthoid sheeting ingase isetshenziselwe le njongo.
Zonke izinto ezifakwayo nezinto ezisindayo njengamavalvu ensimbi yokusansimbi kufanele zisekelwe ukuze kuvinjelwe ukulayishwa kwamaphuzu ezintweni ze-PE. Ukwengeza, lapho kusetshenziswa khona ama-valve, imithwalo ye-torque evela emisebenzini yokuvula / yokuvala kufanele imelane nezisekelo ze-block.
Ukujika kwamapayipi e-PE
Wonke amapayipi e-PE afakwe endleleni egobile kufanele adwetshwe ngokulinganayo kulo lonke ubude bejika, hhayi ngaphezu kwesigaba esifushane. Lokhu kungaholela e-kinking ngobubanzi obuncane, kanye/noma amapayipi odonga amancane.
Amapayipi amakhulu e-PE (angama-450mm nangaphezulu) kufanele ahlanganiswe ndawonye, bese edonselwa ngokulinganayo endaweni oyifunayo. Ibanga elincane elivumelekile lokugoba irediyasi yepayipi le-HDPE lingatholwa.
I-Relining & Non-Dig Trench
Amapayipi akhona angalungiswa ngokufaka amapayipi e-CHUANGRONG PE emapayipini amadala. Amapayipi okufaka angadonselwa endaweni yawo ngamawintshi ayimishini. Ukuxhuma ngamapayipi e-PE kunikeza isici sesakhiwo esikwazi ukumelana nokucindezela kwangaphakathi noma ukulayisha ngaphandle ngaphandle kokuncika emandleni ayinsalela ezakhi zamapayipi acekeleke phansi.
Amapayipi e-PE adinga indawo yokungena kanye nemisele ephumayo ubude ukuze ifake irediyasi yepayipi le-PE ukuze lingene epayipini elikhona, kanye nokuhlanganisa iwintshi okusetshenziselwa ukudonsa i-PE liner eduze kwepayipi. Ubuncane berediyasi yokugoba ye-PE liner ingabalwa njengoba kuchazwe ngaphansi kwePipeline Curvature yebhukwana.
Amapayipi e-PE angasetshenziswa futhi kumaphrojekthi okungewona wokumba, njenge-Horizontal Directional Drilling (HDD). Okunye ukusetshenziswa kwasekuqaleni kwepayipi elikhulu le-PE eliwububanzi bokubhoboza indawo okuwela imifula. Ipayipi le-PE likufanelekele lokhu kufakwa ngenxa yokubekezelela ukuklwejwa kanye nesistimu yokujoyina ehlanganisiwe enikeza ijoyinti lezinga lokuvuza elinguziro elinamandla okuqina okuklama alingana nalawo epayipi.
Kuze kube manje, ababhulayo abaqondisayo bafakile ipayipi le-PE likagesi, amanzi, namapayipi endle; imigudu yokuxhumana; kanye nezinhlobonhlobo zemigqa yamakhemikhali.
Lezi zinhlelo azihileli nje kuphela ukuwela imifula kodwa futhi nokuwela imigwaqo emikhulu kanye nelungelo lokudlula ezindaweni ezithuthukisiwe ukuze kungaphazamisi imigwaqo, imigwaqo nezindawo zokungena amabhizinisi.
Ukulungisa Nokunakekela
Ngokusho komonakalo ohlukahlukene, kunezinhlobo zobuchwepheshe bokukhanda ongakhetha kuzo. Ukulungisa kungenziwa epayipini elincane eliwububanzi ngokuvula isikhala esanele somsele nokusika isici. Buyisela ingxenye eyonakele ngesegimenti entsha yepayipi.
Ukulungisa ipayipi elikhulu lobubanzi kungafezwa ngesiqephu se-spool esine-flanged. Isigaba esilimele siyasuswa.Okulandelayo, umshini wokuhlanganisa izinqe wehliselwa emgodini.Izixhumanisi ezinama-flanged zihlanganiswa ekugcineni okuvulekile, futhi ukuhlanganiswa kwe-spool okune-flanged kuboshwe endaweni. I-spool ene-flanged kufanele yenziwe ngokunembile ukuze ilingane negebe eliwumphumela wepayipi.
