Ukuthuthukisa Ingqalasizinda Yendle Ngokusebenzisa Amapayipi Asenziwe Nge-ARC aphakathi nendawo (SSAW)

Ukuthuthukisa Ingqalasizinda Yendle Ngokusebenzisa Amapayipi Ahlanganisiwe Wokungena Kwe-ARC (SSAW)

Incazelo emfushane:

Le ngxenye yaleli Zinto YaseYurophu icacisa izimo zokulethwa kwezobuchwepheshe ezibandayo ezakhiwe ezihlelekile, izigaba eziyize zamafomu eziyindilinga, izikwele noma amanxantathu futhi zisebenza ezigabeni eziyize zokwakheka ezakhiwe ukubanda ngaphandle kokwelashwa okushisa okulandelayo.

Uhlelo olusebenzayo lwendle lubalulekile ekukhuleni nasekuthuthukisweni kwanoma yiliphi idolobha. Ekwakheni nasekugcinweni kweumthungiulayinis, Ukukhetha amapayipi afanele nezindlela zokufaka zibalulekile. Kuvunguza amapayipi e-arc engaphansi (SSAW) ukuthi abe yisixazululo esithembeke kakhulu nesingabizi sengqalasizinda yokuhambisa indle. Inhloso yaleli bhulogi ukuKhanyisela ngezinzuzo kanye nokusetshenziswa kwepayipi elifakwe emanzini afakwe emanzini angenamikhawulo ekwandiseni izinhlelo zokuhambisa indle.

Ukubuka konke kwepayipi elifakwe emzimbeni we-arc

Kuvunguza i-arc efakwe emgodini, eyaziwa kakhulu ngokuthi ipayipi le-arlc efakwe endaweni efakwe emanzini, lenziwa ngokugoqa insimbi eshisayo evuthayo ibe ngesimo sezulu futhi iwufaka emfuleni we-welding wakwizimpi. Lawa mapayipi anikela ngezinga eliphakeme lokuqina, amandla kanye nokuphikiswa kokugqwala, okwenza balungele amaphrojekthi wengqalasizinda abucayi abanjengabathungi.

Izinzuzo zepayipi le-SSAW kuzinhlelo zokusebenza zendle:

1. Ukuqina: Amapayipi angenamikhawulo e-Welked aredwed akhiwe ngensimbi esezingeni eliphakeme futhi anokuqina okuhle kakhulu. Banamandla okubekezelela imithwalo esindayo kanye nezimo ezisezingeni eliphansi, eqinisekisa impilo ende yenkonzo yamapayipi wendle.

2. Ukumelana nokuqina Le mpahla ibaluleke kakhulu ezinhlelweni zokuhambisa indle ngoba zivame ukubhekana nezimo ezinolaka namakhemikhali.

I-3. Design evubhile Lesi sici sivimbela noma yikuphi okungenzeka ukungena noma ukuvuza, ngaleyo ndlela kunciphise amandla okungcoliswa komhlaba kanye nesidingo sokulungiswa okubizayo.

I-4. Ukuvumelana nezimo nokuzivumelanisa ngezimo eziguqukayo Bangakwazi ukuzivumelanisa nezinguquko kalula kwezwe nokuqondiswa, baqinisekise ukuhamba okubushelelezi kwamanzi amdaka ethule ngisho nakumanethiwekhi anzima wendle.

I-5. Ukusebenza kwezindleko: Uma kuqhathaniswa nezinto zokuhambisa indle zendle zendle ezifana nokhonkolo noma ubumba, amapayipi angenamikhawulo e-arc efakwe emanzini angenazithelo anganikeza ukonga izindleko ngokufaka nokulungiswa. Imvelo yabo engasindi inciphisa izindleko zokuthumela futhi kulula ukuyifaka, ukunciphisa izidingo zabasebenzi. Ngokwengeziwe, impilo yayo ende yenkonzo kanye nezidingo zokugcina okuncane kunomthelela ekusebenzeni kwezindleko zesikhathi eside.

Inani eliphakeme le-nitrogen alisebenzi uma ukwakheka kwamakhemikhali kukhombisa okuqukethwe okuphelele kwe-AL ye-AL ye-0,020% ngesilinganiso esingu-2: 1, noma uma kungenjalo ezinye izinto ezibophayo ze-N zikhona. Izinto ezibophayo ze-N-Bonding zizoqoshwa kudokhumenti lokuhlola.

Izicelo zamapayipi we-SSAW ezinhlelweni zendle:

1. Amanethiwekhi kamasipala wokuhambisa indle Amandla abo nokumelana nokugqwala kubenza babe ukukhetha okuhle kakhulu kokuhambisa amanzi angcolile amabanga amade.

2. I-Stormwater drainage:Amapayipi we-SSAWIngaphatha ngempumelelo i-Stormwater Runoff futhi ivikele izikhukhula ezindaweni zasemadolobheni. Ukuqina kwabo kuvumela ukuhanjiswa okusebenzayo kwemithambo emikhulu yamanzi ezindaweni eziphakeme zamanzi.

I-3. Isitshalo sokwelashwa sendle Ukumelana kwabo namakhemikhali awonakalisayo kanye nekhono lokuphatha izingcindezi ezahlukahlukene ukuzenza zibe zibaluleke kakhulu ezindaweni ezifunwayo.

Ekuphetheni:

Ukukhetha izinto ezifanele zepayipi kubalulekile ekwakhiweni okuphumelelayo nokulungiswa kohlelo lwakho lwendle. Kuvunguza i-ARC PIPE (SSAW) ukuthi iyisisombululo esisebenza ngemali esibizayo, esihlala isikhathi eside futhi esiguquguqukayo. Ngokumelana kwabo okuhle kakhulu kokugqwala, ukwakheka kobufakazi bokuvuza, nokuvumelana nezimo ezindaweni ezahlukahlukene, amapayipi e-SSAW angakwazi ukuhambisa kahle amanzi angcolile, afaka isandla ekuthuthukisweni okuqhubekayo kwamadolobha. Ukusetshenziswa kwamapayipi we-welded we-welded afakwe emanzini aphakathi nendawo kumaphrojekthi wensimbi angavula indlela amanethiwekhi athuthukisiwe ukuze ahlangabezane nezidingo ezikhulayo zokuthuthukiswa kwamadolobha.
