Ukubaluleka Kwezinqwaba Zamashubhu Ensimbi Ekwakhiweni Kwelayini Yamanzi Angaphansi

Ukubaluleka Kwezinqwaba Zamashubhu Ensimbi Ekwakhiweni Kolayini Wamanzi Angaphansi Kwaphansi Isithombe Esifakiwe

Incazelo emfushane:

Inqwaba ye-Tubular yensimbiayingxenye ebalulekile yokwakhiwa kwamapayipi amanzi angaphansi komhlaba, ahlinzeka ngosekelo oludingekayo lwesakhiwo kanye nokuqina ukuze amelane nezimo ezihlukahlukene zemvelo kanye nemvelo.I-spiral welded pipe, ikakhulukazi, isibe yisinqumo esithandwayo ngenxa yokucaciswa kwayo okuyingqayizivele kanye nezinzuzo ekusetshenzisweni komugqa wamanzi angaphansi komhlaba.

Lapho kwakhiwa imigqa yamanzi angaphansi komhlaba, ukukhethwa kwezinto ezibonakalayo kudlala indima ebalulekile ekuqinisekiseni ubuqotho besikhathi eside nokusebenza kahle kohlelo.Inqwaba ye-Tubular yensimbis, ngokuvamile eyaziwa ngokuthi amapayipi, asetshenziswa kabanzi ngenxa yamandla awo aphakeme, ukumelana nokugqwala kanye nokuguquguquka.Kulokhu, amapayipi ashiselwe okuvunguzayo ayisinqumo esihle sokwakhiwa kwamapayipi amanzi angaphansi komhlaba ngenxa yokucaciswa kwawo kanye nezinzuzo ezithile.

Amapayipi ashiselwe ku-Spiral akhiqizwa kusetshenziswa inqubo yokushisela i-spiral seam, engakha i-spiral weld eqhubekayo ngobude bepayipi.Lobu buchwepheshe bokushisela abuqinisekisi nje kuphela ukuvumelana kanye nekhwalithi ephezulu yama-welds, kodwa futhi kukhiqiza amapayipi anama-diameter amakhulu nezindonga eziwugqinsi, okubenza bafaneleke izimo ezinzima zokufakwa kwamapayipi amanzi angaphansi komhlaba.

Esinye sezici eziyinhloko zepayipi elishiselwe okuvunguzayo yikhono lokuzuza ukunemba okukhulu nobuqotho uma kuqhathaniswa nepayipi elishiselwe ngomthungo oqondile.Lesi sici sibaluleke kakhulu ekwakhiweni komugqa wamanzi angaphansi komhlaba, lapho ukuqondisa kahle kwamapayipi nokugeleza kwamanzi okufanayo kubalulekile ekusebenzeni kahle kwesistimu.Ukwengeza, ingaphakathi elibushelelezi lamapayipi ashiselwe okuvunguzayo kunciphisa ukungqubuzana nokwehla kwengcindezi, kusize ukwandisa ukusebenza kahle kwamanzi nokunciphisa ukusetshenziswa kwamandla.

Ngaphezu kwalokho, Kuvunguza ashiselwe ipayipi iyatholakala ezihlukahlukene materials kanye ezinengilazi ukuhlangabezana nezidingo ezithile zemvelo kanye nokusebenza.Kusukela ku-carbon steel kuya ku-alloy nensimbi engagqwali, lawa mapayipi anikeza ukumelana okukhethekile nokugqwala, ukusabela kwamakhemikhali kanye nokucindezeleka komshini, okuqinisekisa ukwethembeka kwesikhathi eside ekufakweni kwemigqa yamanzi angaphansi komhlaba.Ngaphezu kwalokho, izintambo ezivikelayo ezifana ne-epoxy, i-polyethylene, ne-polyurethane zingasetshenziswa ukwandisa ukuqina nokuphila kwesevisi yamapayipi ashiselwe okuvunguzayo, ikakhulukazi emhlabathini obolayo nezimo zamanzi angaphansi komhlaba.

Mayelana nokufakwa, ama-Steel Tubular Piles, okuhlanganisa namapayipi ashiselwe asontekile, anezinzuzo ezinkulu ekwakhiweni kwamapayipi amanzi angaphansi komhlaba.Umthamo wabo ophezulu wokuthwala umthwalo kanye nobuqotho besakhiwo kuvumela ukungcwatshwa okujulile nokusekelwa kwemigudu yamanzi, ngisho nasezimweni ezinzima zenhlabathi kanye nezimo zejoloji.Ngaphezu kwalokho, imvelo engasindi yamapayipi ensimbi yenza kube lula ukuphatha nokuthutha, ukunciphisa isikhathi sokufaka nezindleko.Ipayipi le-Spiral welded lingaxhunywa kalula kusetshenziswa ukucushwa okuhlukahlukene kokuhlanganisa, ukuhlinzeka ngesixazululo esiguquguqukayo nesisebenzayo samaphrojekthi wemigqa yamanzi angaphansi komhlaba.

Ngamafuphi, ukusetshenziswa kwe-Steel Tube Piles (ikakhulukazi amapayipi ashiselwe asontekile) kubalulekile ekwakhiweni ngempumelelo kwamapayipi amanzi angaphansi komhlaba.Ngokucaciswa kwayo okuyingqayizivele, okuhlanganisa ukunemba okuphezulu kwe-dimensional, ukumelana nokugqwala kanye nokuguquguquka kokufakwa, ipayipi elihlanganisiwe elivunguzayo linikeza inhlanganisela engcono kakhulu yamandla nokusebenza kobuqotho bepayipi lamanzi lesikhathi eside.Njengoba isidingo sengqalasizinda yamanzi ethembekile nesimeme sikhula, ukubaluleka kokusebenzisa izinga eliphezuluInqwaba yeTube yensimbisemanzini angaphansi ukwakhiwa umugqa awukwazi overstated.
