Ukubaluleka kwe-tubular yentsimbi yentsimbi yolwakhiwo lomgca wamanzi aphantsi komhlaba

Ukubaluleka kwe-subiles yentsimbi yentsimbi kumgca wamanzi aphantsi komhlaba obonisiweyo

Inkcazo emfutshane:

Imfumba yentsimbi yentsimbiS Ngaba icandelo elibalulekileyo lolwakhiwo lwemibhobho yomhlaba wamanzi, ukubonelela ngenkxaso eyimfuneko yokwakhiwa kunye nokuqina ukumelana neemeko ezahlukeneyo zendalo esingqongileyo kunye neemeko zejografi. I-Spiral Delded Pipe, ngokukodwa, iye yaba lukhetho oludumileyo ngenxa yenkcazo kunye nezibonelelo zosetyenziso lwamanzi aphantsi komhlaba.

Iimpawu zeMveliso

Xa wakha imida yamanzi aphantsi komhlaba, uKhetho lwezinto ezibonakalayo udlala indima ebalulekileyo ekuqinisekiseni ingqibelelo yexesha elide kunye nokusebenza kwempumelelo kwenkqubo.Imfumba yentsimbi yentsimbis, edla ngokuqhelekileyo njengemibhobho, isetyenziswa ngokubanzi ngenxa yamandla abo amakhulu, ukumelana nokungasebenzi kakuhle kunye nokungasebenzi kakuhle. Kule meko, imibhobho ye-Welding ye-Welfed yeyona ndlela ifanelekileyo yokwakhiwa kwamanzi phantsi komhlaba phantsi komhlaba ngenxa yeenkcazo zabo kunye nezibonelelo zazo.

Imibhobho ye-Welfled Welding yenziwa esebenzisa inkqubo ye-spilral seam selding, enokwenza i-spiral yedle ye-spil deble ubude bombhobho. Itekhnoloji ye-Welding ayikuqinisekisi ukungqinelana kunye nomgangatho ophezulu we-wels, kodwa ikwavelisa imibhobho eneedayimitha ezinkulu kunye neendonga ezinzima, zisenza balungele iimeko ezinobungozi.

Enye yezona zinto ziphambili zombhobho we-spiral welding kukufezekisa ukuchaneka okukhulu kunye nokuthe tye xa kuthelekiswa nombhobho we-Weld. Eli nqaku libaluleke ngokukodwa kulwakhiwo lwamanzi aphantsi komhlaba, apho ulungelelwaniso lombhobho ochanekileyo kunye nokuhamba kwamanzi aphezulu kubalulekile kwintsebenzo yenkqubo efanelekileyo. Ukongeza, umda ongaphakathi wemibhobho we-weldiral welding inciphisa ukuxabana kunye noxinzelelo, ukunceda ukonyusa ukusebenza kwamanzi kunye nokunciphisa ukusetyenziswa kwamandla.

Ukongeza, umbhobho we-Welding Welding ufumaneka kwizixhobo ezahlukeneyo kunye neengubo ukuze ufezekise iimfuno ezithile zokusingqongileyo nokusebenza. Ukusukela kwintsimbi yekhabhoni ukuya kwi-alloy kunye nentsimbi engenasimo, le mibhobho inika ukungavisisani okukhethekileyo kokusula, ukuphendula kwamachiza kunye noxinzelelo lwexesha elide, ukuqinisekisa ukuthembeka kwexesha elide kwizicelo zamanzi aphantsi komhlaba. Ukongeza, iingubo ezikhuselayo ezinje nge-Eposteylene, i-Polythylene, kwaye iPolythythane inokusetyenziswa ukwandisa ukuqina kunye nenkonzo yenkonzo ye-spiral welding, ngakumbi kumhlaba ongaphantsi komhlaba kunye neemeko zamanzi ezibuthathaka.

Malunga nokufakwa, iipilisi zentsimbi zentsimbi, kubandakanya imibhobho edlwenguleyo ye-Welf, zinezibonelelo ezibalulekileyo kulwakhiwo lomsebenzi wamanzi aphantsi komhlaba. Ukugcina kwabo umthwalo kunye nokunyaniseka kwesakhiwo esiphezulu sivumela umngcwabo onzulu kunye nenkxaso yamanzi, nokuba ngumceli mngeni kunye neemeko zejografini. Ukongeza, indlela elula yemibhobho yentsimbi ixhasa ukuphatha kunye nokuhamba, ukunciphisa ixesha lokufakelwa kunye neendleko. I-Spiral Deling Pipe inxibelelana ngokulula kusetyenziswa iintlobo ezahlukeneyo zokucwangcisa, zibonelela ngesisombululo esiguquguqukayo nesisebenza kakuhle kwiiprojekthi zemihlaba yamanzi aphantsi komhlaba.

Kwisishwankathelo, ukusetyenziswa kwe-pile ye-puzle yentsimbi (ngakumbi imibhobho ye-Welding ye-Welf) ibaluleke kakhulu kulwakhiwo oluyimpumelelo lwamanzi amdaka aphantsi komhlaba. Ngeenkcukacha zayo ezahlukileyo, kubandakanya ukuchaneka okuphezulu, ukuxhathisa okuphezulu kunye nokufakelwa kwe-Poiper Pleed ibonelela ngeyona ndlela idibeneyo yamandla kunye nentsebenzo yokugcina umbhobho wokugcina umbhobho wamanzi wexesha elide. Njengoko imfuno yeziseko zophuhliso ezinokuthenjwa nezinzileyo ziyakhula, ukubaluleka kokusebenzisa umgangatho ophezuluI-tube ye-tube yentsimbisKumgangatho wamanzi aphantsi komhlaba awunakuba ngaphezulu.
