Indlela Yokukhetha Nokucacisa Ithangi Lokugcina Amanzi Omlilo
Ukukhetha nokucacisa ithangi lokugcina amanzi omlilo kuwumsebenzi wokubhala idokhumenti: i-RFQ ephelele kufanele inqume umthamo nesikhathi, ukucaciswa kwe-coating noma i-enamel, isethi yesitifiketi, imithwalo yokuzamazama komhlaba nomoya, kanye nendlela yokuhamba kanye nemibandela yokufaneleka komhlinzeki ngaphambi kokuba noma yiliphi ithangi licashunwe.
Umehluko phakathi kwethangi lamanzi okuqeda umlilo elifika lihambisana nemigomo nokuthi lelo elibangela ukuhlolwa okwenqatshiwe ngokuvamile lilele ekucacisweni okubhalwe ngaphambili. Le ndatshana ibheka ithangi lokugcina amanzi okuqeda umlilo isuka edeskini lokuthenga: ukuthi isicaciso ne-RFQ kufanele kube nakho ini, indlela yokusho izidingo zokumboza nokugunyazwa ngaphandle kokungaqondakali, kanye nendlela yokuhlola umhlinzeki wethangi lamanzi okuqeda umlilo ngaphezu kwentengo. Umbono uwumbhalo wesicaciso ngokwawo, ohlukile ohlwini lokuhlola umhlinzeki, futhi uhlala ngaphakathi kwemigomo eshiwo kanye nemingcele eqinisekisekayo.
Ukucaciswa Kufanele Kuqale Kucacise Umthamo, Isikhathi, Nomsebenzi Wethangi
Ngaphambi kokuba imibuzo ye-coating noma yomhlinzeki ivele, ukucaciswa kufanele kusho umthamo ozokwethulwa, isikhathi esidingekayo somlilo, nomsebenzi — i-sprinkler, i-hydrant, i-standpipe, i-deluge, noma okuhlanganisiwe. Lokhu kuchaza usayizi wethangi kanye nebhendi engasetshenziswa iphampu ye-NFPA 20 engakwazi ukuyidonsa. Ukucaciswa okushiya umthamo noma isikhathi kuvulekile kuphoqa wonke umuntu obhidayo ukuthi acabange izinombolo ezihlukile, okukhiqiza izicelo zokucashunwa ezingenakuqhathaniswa. Ithebula elingezansi libala amapharamitha omsebenzi amancane okucaciswa okufanele kuwacacise.

Imithwalo Yokuzamazama Komhlaba, Yomoya, Neyesisekelo Kufanele Icaciswe, Hhayi Ukucatshangwa
Ithangi elanele ngokwesakhiwo endaweni eyodwa lingase lihluleke kwenye indawo uma imithwalo ingacacisiwe. I-spec kufanele ibhekisele ezindinganisweni ezifanele zomthwalo — i-ASCE 7 ne-EN 1991-1-4 yomoya, i-EN 1998-4 yokuzamazama komhlaba lapho kusebenza khona — futhi iveze imingcele yokuklama yendawo. Emathangini aboshiwe, ukucaciswa kwesisekelo ne-anchor kuyingxenye yomsebenzi womhlinzeki futhi kufanele kuxhumaniswe nokuklama kwesakhiwo ukuze isisekelo sethangi, igobolondo, nophahla kumelane nezinhlanganisela ezicacisiwe.
I-Logistics, Ububanzi Bokwakhiwa, Kanye Nokuhlolwa Kufanele Kubhalwe Ku-RFQ
Amathangi omlilo okuthunyelwa ngaphandle alethwa njengamapuleti noma amakhithi, futhi i-RFQ kufanele iveze ukuthi ubani owakha ithangi, ubani ohlinzeka ngesisekelo, futhi yikuphi ukuhlolwa okudingekayo efemini nasendaweni. Ukungacaci lapha yilapho amaphrojekthi ehla khona esimisweni sawo. Isicaciso kufanele sisho izivivinyo zokwamukela — isivivinyo se-spark se-enamel, ukuhlolwa kobukhulu, kanye nesivivinyo se-hydrostatic lapho kufanele khona — futhi sabela umthwalo wemfanelo kulokho ngakunye. Isigaba esicacile se-logistics nokwakhiwa siguqula ukuhlinzekwa kwethangi kube uhlelo olulethwayo.
Ukuhlolwa Komhlinzeki Kufanele Kubheke Umthamo, Amalungelo Obunikazi, Kanye Nomlando Wokusebenza, Hhayi Intengo Kuphela
Umhlinzeki wamathangi okugcina amanzi omlilo kufanele ahlolwe ngokwamandla akhe abonakalayo: iminyaka yokwakhiwa kwamathangi aboshiwe, izinga lokukhiqiza, inani lamaphrojekthi afakiwe, amazwe akhonzwayo, kanye nohlu lwezitifiketi. Lezi ziwuphawu olubonakalayo lokuthi umhlinzeki angaletha yini ithangi elihambisana nemithetho ngokuphindaphindiwe. Ukuqhathanisa intengo kusebenza kuphela ngemuva kokuthi isicaciso senze ububanzi bobuchwepheshe bufane phakathi kwababhidi; ukuhlola amandla kuqinisekisa ukuthi ibhidi ephansi kakhulu nayo inekhono elifanele.
Icala Lomsebenzi
