Itanki ye-LPG yomhlaba kunye netanki elingaphantsi komhlaba linoqoqosho ngakumbi ngokwendlela yokusetyenziswa komhlaba, iindleko kunye nokhuseleko?
Umhla: Feb 05, 2020
Ngubani onesibonelelo seitanki elingentlaye-LPG (igesi yerhasi yerhasi yerhasi yokugcina irhasi xa ithelekiswa neetanki eziphantsi komhlaba? Makhe sithelekise izinto ezintathu zokusetyenziswa komhlaba, iindleko kunye nokhuseleko.
I-1. Umhlaba
Kule mihla, ixabiso lomhlaba liyenyuka yonke indlela, elinokuchazwa njengobukhulu bomhlaba. Ngokwezixhobo ze "Ikhowudi yoyilo lwesixeko": Ivolumu yetanki enye yetanki ayidluli kwiimitha ezingama-50, kwaye uninzi lwamakhono aludluli kwi-400 yeemitha. Ingancitshiswa sisiqingatha xa kuthelekiswa netanki eliphantsi, kwaye ezinye iindlela zokhuseleko zinokuncitshiswa. Ke ngoko, ukuba umthamo wakho uwonke ungaphantsi kweemitha ezingama-400, ukhetha i-LPG itanki engaphantsi komhlaba ingagcina indawo yomhlaba. Umzekelo, ukuba ukwakha iimitha ezimbini ezingama-50, iimitha ezili-20, kunye namandla e-120 eemitha, ukuba kukho iitanki zomhlaba, kodwa zifuna iitanki zomhlaba, kodwa ziyi-2 000 zomhlaba kuphela.

I-LPG phantsi kweetanki ezingaphantsi komhlabaYiba ne-DN450 i-manholes engaphezulu koyilo olunezinto ezikhoyo zetanki, ukuze ixabiso letanki lokugcina ilula iya kuba nexabiso elikhulu ngakumbi kunelo leetanki ze-LPG. Ukongeza, i-LPG yeetanki ezingaphantsi komhlaba ziyangcwatywa phantsi komhlaba, ukwenzela ukuthintela umhlaba corrode umphezulu wetanki. Itanki nganye yokugcina kufuneka inyangwe nge-anticorrosion, kwaye isiseko setanki yogcino kufuneka ibe ngaphantsi komhlaba malunga neemitha ezi-4 ukusuka emhlabeni. Indleko ukwakhiwa koluntu kuya kuba phezulu kakhulu kunelo tanki ngaphezulu komhlaba. Umphezulu wetanki elingcwatywe kufuneka lizaliswe yisanti ubuncinci i-400 mm ubukhulu. Umsebenzi wokufakelwa ubalekile ngakumbi kunetanki yomhlaba, umthwalo mkhulu, kwaye iindleko zokufakelwa ziya kunyuka. Ke ngoko, ukuba umhlaba wakho ubanzi, inani leetanki zomhlaba ziya kuba zincinci kakhulu.
3. UKHUSELEKO
Kuba uyilo lwangoku kunye nofakelo lwezikhululo ze-LPG ziphononongwe kwaye zijongiwe ngamaziko awodwa okuhlala ehlotyeni, ukhuseleko lwendalo, i-meteorology, iiprojekthi zokwakha ezongekho semthethweni aziyi kudlula. Emva kokuba kufakwe umbhobho wonke, iimvavanyo zomoya kunye novavanyo olungelo nisonakalisayo zenziwa. Ezinye izixhobo zokubeka iliso ezinje nge-alamu yotywala yegesi kunye neenkqubo zokuvalwa kwexesha elingxamisekileyo kufuneka zifakwe kwisikhululo segesi. Ke ngoko, lo gama umsebenzisi esebenza kwaye esebenza ngokwemigaqo, akukho mahluko mkhulu ekukhuseleni, kwaye zombini zikhuselekile.
