Imibhobho yentsimbi ye-Spiral idla ngokusetyenziswa kwimibhobho yokuhambisa amanzi edolophini. Ukusetyenziswa kwemibhobho yentsimbi ejikelezayo kwiinkqubo zemibhobho yokuhambisa amanzi ezidolophini lulungiselelo olubanzi lonikezelo lwamanzi ezidolophini, unikezelo lwamanzi, unikezelo lwamanzi, ukuhanjiswa kwamanzi amdaka, ukucocwa kogutyulo, kunye nezinye iinkqubo zemibhobho kunye neenxalenye zazo ezahlukeneyo kwixesha elithile. Ulungelelwaniso lulonke lwesicwangciso sombhobho wamanzi ezidolophini lubaluleke kakhulu, kwaye iindlela ezahlukeneyo zokulondolozwa kwamanzi okunokwenzeka kunye nokuhanjiswa kwamanzi kufuneka kuphuculwe kwaye kudityaniswe. Ukuza kuthi ga ngoku, kufuneka siqale siqonde isicwangciso samanzi asezidolophini, someleze isicwangciso samanzi esikhethekileyo kwisicwangciso esipheleleyo sedolophu, kwaye silungiselele isicwangciso samanzi asezidolophini ngombono wophuhliso lwamanzi oluzinzileyo. Umxholo kufuneka uquke amanzi aphezu komhlaba, amanzi aphantsi komhlaba, amanzi emvula kunye namanzi olwandle, ukulungelelana kobutyebi, ubonelelo lwamanzi, ukuhanjiswa kwamanzi kunye nokuphinda kusetyenziswe ugutyulo; unikezelo lwamanzi kunye nesicwangciso solondolozo lwamanzi kunye nokucocwa kogutyulo kunye nesicwangciso sohlaziyo; isicwangciso somjikelo wendalo yamanzi; Ubonelelo ngamanzi kunye nezibonelelo zobunjineli zemibhobho yokuhambisa Ubungakanani kunye noyilo.

Ngokumalunga neengxaki eziqhelekileyo zokucwangciswa okungalungelelanisiweyo, ulwakhiwo olungahambelaniyo, kunye nolawulo olungaguquguqukiyo ekwakhiweni konikezelo lwamanzi asezidolophini kunye neenkqubo zemibhobho yokuhambisa amanzi amdaka kwilizwe lam, ingqwalasela eyodwa kufuneka ihlawulwe kuphuhliso olulungelelanisiweyo longqamaniso lwemibhobho kunye nonikezelo lwamanzi kunye nokuhanjiswa kwamanzi. Umthamo wokusetyenzwa ocwangcisiweyo kunye nobungakanani benkqubo yonikezelo lwamanzi lwangaphakathi lwenkqubo yonikezelo lwamanzi kunye nezibonelelo zayo zothungelwano ngexesha locwangciso kufuneka zichazwe kwisicwangciso soyilo kunye nolawulo lokusebenza.

Uyilo lwemibhobho yentsimbi ejikelezayo kwimibhobho yokuhambisa amanzi kufuneka ihlangabezane neemfuno zezicwangciso zommandla kunye needolophu kunye nokuqwalasela ngokupheleleyo ukulinganisa kwenkqubo. Ukulula ukugcinwa kunye nokuhlolwa kwenkqubo yamanzi kufuneka kuqwalaselwe kuyilo, kwaye imibhobho kufuneka ibe mfutshane kwaye isebenze ngokusemandleni.

Umbhobho wentsimbi ojikelezayo ngumbhobho wentsimbi ojikelezayo owenziwe ngentsimbi yomtya okanye ebhijelwe kwimilo engqukuva. Amalungu angaphakathi kunye nangaphandle anecala eliphindwe kabini le-arc esebenzayo ye-welding. Ngenxa yezi zizathu zilandelayo, inokusetyenziswa ngokubanzi kwimveliso yamanzi, umbane, imichiza kunye namanye amashishini. Kufuneka kuphela ukutshintsha i-angle yokubumba ukuvelisa imibhobho yentsimbi yeedayamitha ezahlukeneyo ezinobubanzi obufanayo, kwaye kulula ukuyilungisa.

Ekubeni yenziwe ngokujija ngokuqhubekayo kunye nokujika, ubude bombhobho wensimbi ojikelezayo abukhawulelwanga kwaye ubude bunokumiselwa ngokuthanda. Ubume be-weld spiral busasazwe ngokulinganayo kwisangqa sombhobho wentsimbi ejiyileyo, ngoko ke umbhobho wentsimbi ejiyileyo unobume obuchanekileyo kunye namandla. Kulula ukutshintsha isikali, esifanelekileyo kwimveliso encinci yebhetshi kunye neentlobo ezahlukeneyo zemibhobho yentsimbi ejikelezayo.

Ngokubanzi, i-weld seams zemibhobho yentsimbi ejikelezayo mide kuneyo yentsimbi yomthungo wemibhobho yomgangatho ofanayo, kwaye uxinzelelo olunyamezelwa yimibhobho yentsimbi ejikelezayo iyafana phantsi kobukhulu obufanayo bodonga.

Ukulungelelanisa kwiimfuno zemveliso yanamhlanje, ixesha lokuvelisa i-spiral steel pipe liye laba lifutshane kwaye lifutshane, kwaye ixabiso lemveliso liye laba liphantsi kwaye liphantsi. Ngoko ke, iibhobho zentsimbi ezijikelezayo ziye zatshintsha ngokuthe ngcembe ukusetyenziswa kwentsimbi yomjelo.
