Ukususwa Kweqhwa Eliyisicaba Eluphahleni Lwezentengiselwano: Indlela Yokususa Iqhwa Ngaphandle Kokuchitha Iwaranti Yakho Ye-TPO/PVC

Isiphepho saphela ngobusuku obubodwa. Ngo-6 ekuseni, umphathi wephrojekthi usemi esizeni ebheke phezulu ophahleni oluneqhwa eliningi kakhulu kunanoma ubani ofuna ukulibona.

Iqembu liyahlelwa. Amafosholo ensimbi, ama-ice picks, mhlawumbe umshini omncane wokufutha. Emini uphahla lusuke selucwebile futhi i-invoyisi iyinto ejwayelekile yomugqa.

Ibhili langempela lifika entwasahlobo. Umthungo waqhekeka. Ulwelwesi lwafakwa uphawu ngomphetho wefosholo. Lapho ukuncibilika kuqala, amanzi athola lowo mbobo omncane, acwilise i-insulation, bese ebonakala njengophahla olunamabala kanye nesikhalazo somqashi. Bese kuba nempikiswano yokuthi ubani okhokhayo.

Amaqembu amaningi ezikhungo abala ukuthi yini Ukususwa Kweqhwa izindleko. Zimbalwa kakhulu ezibala ukuthi kubiza malini uma ukususwa konakalisa uphahla.

Abasebenzi beqhwa kanye nabasebenzi abajwayelekile banekhono lokuhlanza umgwaqo. I-membrane iyindawo ehlukile. Ifosholo elilodwa ekhoneni elingalungile lishiya umugqa wesilinganiso. Ukujikijela okukodwa okuqinile endaweni yeqhwa kushiya ukubhoboka.

Abakhi bophahla bakusho ngokungagwegwesi: ukuthumela umuntu phezulu nefosholo yensimbi kungenye yezindlela ezisheshayo zokubeka engcupheni iwaranti yophahla lwezentengiselwano.

Imithungo ye-TPO ne-PVC ishiselwe ngokushisa. Emazingeni okushisa abandayo ilahlekelwa ukuguquguquka. Ukuhamba kwezinyawo kanye nokucindezela kwamathuluzi eduze kwemithungo, ama-skylight curbs, kanye nokungena kwamapayipi kungabangela umonakalo wokucindezeleka ongakwazi ukuwubona.

Ngeke ivuze ngoJanuwari, ngoba amanzi aqandisiwe. Ivuza ngoMashi, futhi ngaleso sikhathi akekho owayeyixhumanisa nosuku abasebenzi abashaya ngalo ngefosholo.

Ukuhlanza uphahla oluyisicaba oluphakathi nendawo ngesandla kuthatha abantu abaningana namahora amaningana. Ngesiphepho ngasinye, lokho kukhula ngokushesha.

Ingxenye engakhululekile yilokho okutholayo ngaleyo mali. Ukhokhele umsebenzi futhi uthathe nengozi yokonakalisa uphahla. Imali esetshenzisiwe ingokoqobo, kodwa umthwalo wemfanelo usekhona.

Umthwalo weqhwa umayelana nesisindo, hhayi nje ukujula. Iqhwa eligcwele, uhlobo oluhlangana nebhola leqhwa, linesisindo esingaba amakhilogremu angu-20 nge-cubic foot. Iqhwa elomile licishe libe amakhilogremu angu-6–8, kodwa iziphepho ezinkulu zivame ukuthwala umswakama omningi.

Thatha ingxenye engamamitha angu-20×20 eneqhwa eligcwele unyawo olulodwa. Lokho kungaba yi-8,000 lb endaweni eyodwa yophahla. Ezakhiweni ezikhanyisiwe ngensimbi elula, ezingasondela emaphethelweni omngcele womklamo.

Nokho, iqhwa ophahleni aliyona inkinga ngokuzenzakalelayo. Izimpawu zesixwayiso zangempela ukuphambuka okubonakalayo, amanzi ayeka ukusebenza ngendlela evamile, kanye namabala amanzi avela ngaphakathi. Uma kungekho lutho lwalokho, ukuthumela iqembu phezulu kungadala ukuvuza obuzama ukukuvimbela.

Ngakho-ke ukulandelana kubalulekile. Nquma ukuthi uzosula yini, bese unquma ukuthi kanjani. Lokho kuhlela kubalwa ngaphezu kokufoshola uqobo.

Ukubhoboza nokudabuka. Imiphetho yensimbi kanye namathiphu e-pick kubangela umonakalo ongenayo uma kushelela noma kushaya. Isiqondiso sokugcinwa komkhiqizi we-TPO, okuhlanganisa ne-KÖSTER's, sincoma amafosholo epulasitiki ayindilinga esikhundleni sensimbi. Inkinga ukuthi abakhi beqhwa abavamile ukuwaphatha.

Ukuhlukaniswa komthungo. Iqembu elicindezela kakhulu phezu komthungo, noma eliqhekeza iqhwa eceleni kwelinye, lingaqala ukuhlukana okufihliwe ku-weld. Amanzi aqandisiwe ayayifihla kuze kube yilapho incibilika okokuqala.

Ukucindezeleka kwendawo kanye nokuzelula. Amandla agxile onqenqemeni lwe-blade adonsa ulwelwesi endaweni. Ngemva kokuhlanza okuphindaphindiwe ungabona ukushwabana noma ukukhukhumala. Lapho uphahla lwakho luhlola, lobo bufakazi buvame ukuwela ngaphandle kwesiqinisekiso.

Uma abantu bakho bekhuphuka, qinisekisa ukuthi basebenzisa amafosholo epulasitiki futhi bazi ukuthi yiziphi izindawo okufanele bazigweme: imithungo, imingcele ye-skylight, izisekelo zamapayipi. Uma ungakwazi ukuqinisekisa kokubili, sekuyisikhathi sokucabanga ngendlela ehlukile.

I-Tarp Yokususa Iqhwa ishintsha umbuzo. Ukuhlanza ngesandla kusho ukusebenza phezu kophahla. I-Tarp isho ukungasebenzi phezu kophahla.

Ngaphambi kwesiphepho, i-tarp isakazwa endaweni ofuna ukuyivikela. Usayizi ojwayelekile ongu-20×20 no-25×25 ft umboza izingxenye eziningi zophahla lwezentengiselwano. Izinto zokwakha zimbozwe nge-PVC engu-18 oz I-Polyi-ester, ehlala iguquguquka cishe kuze kufike ku--20°F lapho amashidi e-polyethylene ashibhile ephenduka abe buthakathaka. Iqhwa liwela phezu kwethayela, linengqimba ebonakalayo phakathi kwalo ne-membrane.

Ngemva kwesiphepho, i-crane, i-forklift, noma i-loader iphakamisa i-tarp nge-webbing yayo enqenqemeni (elinganiswe cishe amandla okuphuka angu-6,000 lb) kanye nezindawo zokuphakamisa eziqinisiwe. Iqhwa lishiya uphahla ne-tarp. Akukho thuluzi, ibhuzu, noma i-blade ethinta i-membrane nganoma yisiphi isikhathi.

Lena akuyona indlela esheshayo yokufohla. Kuyindlela yokugwema ukufohla, futhi kususa isenzo esibangela umonakalo.

Iwaranti. Abakhiqizi bophahla bavame ukukhipha umonakalo ovela ekususweni kweqhwa okungafanele, futhi amathuluzi ensimbi kulwelwesi ayimbangela evamile yalokho kususwa. Inqubo esekelwe ku-tarp isho ukuthi ulwelwesi aluboni ukuthintana komshini ubusika bonke. Uma kuvela impikiswano yewaranti, lokho kuyirekhodi eliwusizo okufanele ube nalo.

Isibopho sesakhiwo. Abanikazi bezindawo kanye namaqembu alawulayo ngokuvamile banesibopho sokunakekela ngokufanele ukuphepha kwesakhiwo, futhi umthwalo weqhwa ophahleni ungawela ngaphansi kwalowo msebenzi, yize imininingwane ihluka ngokwendawo (hlola nomeluleki wakho). Uma iqhwa eliqongelelekile liba yinkinga yesakhiwo, kungadingeka ubonise ukuthi uthathe izinyathelo ezifanele.

I-Reasonable ayisho ukuthumela abantu phezulu namafosholo, futhi uma ifosholo ngokwayo ilimaza uphahla, ingasebenza ngokumelene nawe. Inqubo ye-tarp ingabhalwa phansi futhi iphindaphindeka: lapho yabekwa, lapho iphakanyiswa, ubani owayiqhuba.

Lokhu akulungile kuwo wonke uphahla. Uhlobo lophahla, umthwalo weqhwa, kanye nokufinyelela ku-crane konke kubalulekile. Uma ungaqiniseki ukuthi uphahla lwakho lufanelana nendlela ye-tarp, ngithumelele uhlobo lwe-membrane kanye nendawo elinganiselwe, ngizokutshela ukuthi lufanelekile yini.

Iyiphi inqubo yakho yamanje yokunquma ukuthi uphahla ludinga ukusulwa, nokuthi ubani osayinayo kulo?
