Iphansi legumbi elihlanzekile linezinhlobo ezahlukene ngokuya ngezidingo zenqubo yokukhiqiza, izinga lokuhlanzeka kanye nemisebenzi yokusetshenziswa komkhiqizo, ikakhulukazi okuhlanganisa iphansi le-terrazzo, iphansi elimboziwe (i-polyurethane coating, i-epoxy noma i-polyester, njll.), iphansi elinamathelayo (ibhodi le-polyethylene, njll.), iphansi eliphakanyisiwe (elishukunyiswayo), njll.
Eminyakeni yamuva nje, ukwakhiwa kwamakamelo ahlanzekile eShayina kuye kwasebenzisa kakhulu phansi, ukupenda, ukumboza (njengokumboza phansi kwe-epoxy), kanye nokumboza phansi okuphakeme (okushukumayo). Ku-"Code for Construction and Quality Acceptance of Clean Factories" (GB 51110) kazwelonke, kwenziwa imithethonqubo kanye nezimfuneko zokwakhiwa kwamaphrojekthi okumboza phansi kanye nokumboza phansi okuphakeme (okushukumayo) kusetshenziswa ukumboza okusekelwe emanzini, ukumboza okusekelwe ku-solvent, kanye nokumboza okuvikela uthuli kanye nesikhunta.
(1) Ikhwalithi yokwakha yephrojekthi yokuhlanganisa umhlabathi egumbini elihlanzekile lokuhlanganisa umhlabathi kuqala incike "esimweni songqimba lwesisekelo". Ezinhlotsheni ezifanele, kuyadingeka ukuqinisekisa ukuthi ukulungiswa kongqimba lwesisekelo kuhlangabezana nemithethonqubo nezidingo zemininingwane efanele yobungcweti kanye nemibhalo ethile yokuklama ubunjiniyela ngaphambi kokwenza ukwakhiwa kokuhlanganisa umhlabathi, nokuqinisekisa ukuthi usimende, uwoyela, nezinye izinsalela ezisengqimbeni yesisekelo ziyahlanzwa; Uma igumbi elihlanzekile liyingqimba engezansi yesakhiwo, kufanele kuqinisekiswe ukuthi ungqimba olungangeni manzi lulungisiwe futhi lwamukelwe njengolufanelekile; Ngemva kokuhlanza uthuli, amabala kawoyela, izinsalela, njll. ebusweni bongqimba lwesisekelo, umshini wokupholisha kanye nebhulashi lensimbi kufanele kusetshenziswe ukupholisha ngokuphelele, ukulungisa nokulingisa, bese kususwa nge-vacuum cleaner; Uma umhlabathi wokuqala wokuvuselelwa (ukwandiswa) uhlanzwa ngopende, i-resin, noma i-PVC, ubuso bongqimba lwesisekelo kufanele bupholishwe kahle, futhi kufanele kusetshenziswe i-putty noma i-samente ukulungisa nokulingisa ubuso bongqimba lwesisekelo. Uma ubuso bengqimba yesisekelo buyikhonkrithi, ubuso kufanele bube lukhuni, bome, futhi bungabi nama-honeycomb, ukuxebuka okufana nempuphu, ukuqhekeka, ukuxebuka, nezinye izinto, futhi kufanele bube yisicaba futhi bubushelelezi; Uma isisekelo senziwe ngethayela le-ceramic, i-terrazzo kanye nepuleti lensimbi, umehluko wokuphakama kwamapuleti aseduze akufanele ube ngaphezu kuka-1.0mm, futhi amapuleti akufanele akhululeke noma aqhekeke.
Ingqimba yokubopha yengqimba engaphezulu yephrojekthi yokubopha phansi kufanele yakhiwe ngokwezidingo ezilandelayo: akufanele kube nemisebenzi yokukhiqiza ngaphezulu noma eduze kwendawo yokubopha, futhi kufanele kuthathwe izinyathelo zokuvimbela uthuli ezisebenzayo; Ukuxubana kwezembozo kufanele kulinganiswe ngokwesilinganiso sokuxuba esibekiwe futhi kuhlanganiswe kahle ngokulinganayo; Ubukhulu bezembozo kufanele bufane, futhi akufanele kube khona ukushiywa noma ukumhlophe ngemva kokusetshenziswa; Lapho kuhlangana khona imishini nezindonga, upende akufanele unamathele ezingxenyeni ezifanele njengezindonga nemishini. Izembozo ezingaphezulu kufanele zihambisane ngokuqinile nezidingo ezilandelayo: isembozo esiphezulu kumele senziwe ngemva kokuba isembozo somile, futhi izinga lokushisa lendawo yokwakha kufanele lilawulwe phakathi kuka-5-35 ℃; Ubukhulu nokusebenza kwezembozo kufanele kuhlangabezane nezidingo zomklamo. Ukuphambuka kobukhulu akufanele kudlule u-0.2mm; Isithako ngasinye kumele sisetshenziswe ngaphakathi kwesikhathi esibekiwe futhi siqoshwe; Ukwakhiwa kwesembozo esiphezulu kufanele kuqedwe ngesikhathi esisodwa. Uma ukwakhiwa kwenziwa ngezitolimende, amalunga kufanele abe mancane futhi abekwe ezindaweni ezifihliwe. Amalunga kufanele abe yisicaba futhi abushelelezi, futhi akufanele ahlukaniswe noma avele; Ubuso bengqimba engaphezulu kufanele bungabi nemifantu, amabhamuza, ukuhlukanisa, imigodi, nezinye izinto; Ukumelana nomthamo kanye nokumelana nobuso bomhlaba omelene nokuqina kufanele kuhlangabezane nezidingo zomklamo.
Uma izinto ezisetshenziselwa ukugqoka phansi zingakhethwanga kahle, kuzothinta ngqo noma ngisho ngokungathi sína ukuhlanzeka komoya kwegumbi elihlanzekile ngemva kokusebenza, okuholela ekwehleni kwekhwalithi yomkhiqizo ngisho nokungakwazi ukukhiqiza imikhiqizo efanelekile. Ngakho-ke, imithetho efanele ibeka ukuthi izakhiwo ezifana nokumelana nesikhunta, ukungangenwa amanzi, okulula ukuzihlanza, ukumelana nokuguguleka, uthuli oluncane, ukungaqongeleli kothuli, kanye nokungakhishwa kwezinto eziyingozi ekhwalithini yomkhiqizo kufanele kukhethwe. Umbala womhlaba ngemuva kokupenda kufanele uhlangabezane nezidingo zomklamo wobunjiniyela, futhi kufanele ufane ngombala, ngaphandle komehluko wombala, iphethini, njll.
(2) Iphansi eliphakeme lisetshenziswa kabanzi emakamelweni ahlanzekile ezimbonini ezahlukahlukene, ikakhulukazi emakamelweni ahlanzekile okugeleza aqonde ngqo. Isibonelo, izinhlobo ezahlukene zephansi eliphakeme zivame ukufakwa emakamelweni ahlanzekile okugeleza aqonde ngqo asezingeni le-ISO5 nangaphezulu ukuqinisekisa amaphethini okugeleza komoya kanye nezidingo zesivinini somoya. IShayina manje ingakhiqiza izinhlobo ezahlukene zemikhiqizo yephansi eliphezulu, kufaka phakathi izitezi ezinomoya, izitezi ezingashukumi, njll. Ngesikhathi sokwakhiwa kwezakhiwo zefektri ezihlanzekile, imikhiqizo ivame ukuthengwa kubakhiqizi abangochwepheshe. Ngakho-ke, ku-GB 51110 kazwelonke ejwayelekile, kudingeka kuqala ukuhlola isitifiketi sefektri kanye nombiko wokuhlolwa komthwalo wephansi eliphezulu ngaphambi kokwakhiwa, futhi imininingwane ngayinye kufanele ibe nemibiko yokuhlola ehambisanayo ukuqinisekisa ukuthi iphansi eliphezulu kanye nesakhiwo salo esisekelayo kuyahlangabezana nezidingo zomklamo kanye nokuthwala umthwalo.
Iphansi lesakhiwo lokubeka izitezi eziphakeme kakhulu ekamelweni elihlanzekile kufanele lihlangabezane nezidingo ezilandelayo: ukuphakama komhlabathi kufanele kuhlangabezane nezidingo zomklamo wobunjiniyela; Ubuso bomhlabathi kufanele bube yisicaba, bushelele, futhi bungabi nothuli, bube nomswakama ongaphezu kuka-8%, futhi kufanele bumbozwe ngokwezidingo zomklamo. Ezitezi eziphakeme kakhulu ezinezidingo zomoya, izinga lokuvula kanye nokusatshalaliswa, ubude bokuvuleka noma bomphetho kungqimba lobuso kufanele kuhlangabezane nezidingo zomklamo. Ingqimba yobuso kanye nezingxenye zokusekela zezitezi eziphakeme kufanele zibe yisicaba futhi ziqine, futhi kufanele zibe nokusebenza okufana nokumelana nokuguguleka, ukumelana nesikhunta, ukumelana nomswakama, ukuvimbela ilangabi noma ukungashi, ukumelana nokungcola, ukumelana nokuguga, ukumelana ne-asidi alkali, kanye nokuqhuba ugesi okungaguquki. Ukuxhumana noma ukubopha phakathi kwezinsika zokusekela zezitezi eziphakeme kakhulu kanye nephansi lesakhiwo kufanele kuqine futhi kuthembeke. Izingxenye zensimbi ezixhumanisayo ezisekela ingxenye engezansi yesigxobo esiqondile kufanele zihlangabezane nezidingo zomklamo, kanye nezintambo eziveziwe zama-bolt okulungisa akufanele zibe ngaphansi kuka-3. Ukuphambuka okuncane okuvumelekile kokubekwa kwengqimba yobuso bobuso obuphakeme kakhulu.
Ukufakwa kwamapuleti ekhoneni esitezi esiphakeme kakhulu ekamelweni elihlanzekile kufanele kusikwe futhi kulungiswe ngokwesimo sangempela endaweni, futhi kufanele kufakwe izisekelo ezilungisekayo kanye neziphambano. Amajoyinti aphakathi komphetho wokusika nodonga kufanele agcwaliswe ngezinto ezithambile, ezingenalo uthuli. Ngemva kokufakwa kwesitezi esiphezulu, kufanele kuqinisekiswe ukuthi akukho ukujikijela noma umsindo lapho uhamba, futhi uqinile futhi uthembekile. Ungqimba olungaphezulu kufanele lube yisicaba futhi luhlanzekile, kanti amajoyinti amapuleti kufanele abe avundlile futhi aqonde phezulu.
