Pov thawj ntawm kev siv cov pob zeb ntuj hauv kev tsim kho tau ntev heev. Cov khoom siv no muaj ntau qhov tshwj xeeb zoo. Nws lub ntsiab tsis zoo yog tus nqi siab thiab kev ua haujlwm nyuaj. Pob zeb tau hloov los ntawm cib, tab sis nws yog muab los ntawm tes, uas yog ntev thiab kim. Cov pob zeb thiab cov pob zeb ua kom muaj zog ntxiv tau ua rau kev nrawm ntawm kev tsim kho. SNiP tswj hwm lawv cov kev siv ntawm cov chaw.
Muaj ntau txoj hauv kev los ua thiab siv cov khoom loj no. Cov tsev nto moo Khrushchev yog cov piv txwv meej tshaj plaws ntawm kev siv vaj huam sib luag siv tshuab. Nrog rau tag nrho nws cov shortcomings, qhov no ua kom muaj tus nqi siab ntawm kev tsim khoom. Kev txhim kho thev naus laus zis ua rau nws tuaj yeem hloov kho cov thev naus laus zis, thiab nyob rau tib lub sijhawm, cov ntaub ntawv tswj hwm kuj tau hloov pauv.
Txoj cai tswj hwm
Lub koom haum profile thiab cov haujlwm tseem ceeb tau koom nrog hauv kev tsim cov cai tshiab hauv tsev. SNiP 2030184 "Concrete and reinforced concrete structures" aims los koom ua kecov txheej txheem ntawm kev tsim cov ntsiab lus hais, nrog rau kev siv tshuab ntawm lawv cov khoom tsim thiab siv. Cov ntaub ntawv kho cov kev xav tau ntawm cov qauv, hauv kev tsim cov silicate pob zeb ntawm cov pab pawg nruab nrab ntom ntom siv.
Raws li cov ntaub ntawv no, cov xwm txheej ib puag ncig tau txiav txim siab uas siv cov khoom siv thauj khoom lossis cov khoom siv los ntawm cov pob zeb uas tau tso cai. Qhov ntsuas kub yog qhov dav heev thiab tau teem rau hauv thaj tsam ntawm -70 ° C txog +50 ° C, uas sib haum mus rau yuav luag txhua qhov chaw huab cua. Kev siv cov pob zeb thiab cov pob zeb muaj zog yog tso cai los ntawm SNiP ntawm qhov txheeb ze av ntawm 75%.
Txoj kev tsim khoom
Cov thev naus laus zis niaj hnub muab rau kev hnav khaub ncaws ntawm cov khoom lag luam ob qho tib si hauv cov xwm txheej ntawm cov chaw tsim khoom tshwj xeeb (ZHBK), thiab ncaj qha rau ntawm qhov chaw. Txoj kev no hu ua monolithic kev tsim kho. Nrog rau cov txheej txheem ua ke, cov khoom tiav, cov pob zeb ua vaj tse thiab cov pob zeb txuas ntxiv. SNiP tswj hwm txhua txoj hauv kev ntawm kev sib txuas cov ntsiab lus nrog ib leeg.
Cov yam ntxwv ua tau zoo ntawm cov qauv monolithic tau nce kev txaus siab rau lawv los ntawm cov neeg siv khoom thiab cov tuam txhab tsim kho. Tsis ntev los no, cov thev naus laus zis no tau raug txhim kho: qhov casting ntawm cov phab ntsa sab nrauv yog nqa tawm nyob rau hauv ib tug taag formwork. Nws yog tsim los ntawm high density extruded polystyrene ua npuas ncauj. Thaum ua tiav kev tsim kho, nws ua lub luag haujlwm ntawm cov txheej txheem cua sov.
Kev cob qhia cov neeg ua haujlwm engineering
Qualitypob zeb cov khoom nyob ntawm qhov tseem ceeb ntawm cov khoom qub thiab kev ua tiav ntawm cov txheej txheem thev naus laus zis. Phau ntawv rau SNiP "Concrete and reinforced concrete structures" yog cov lus qhia rau kev nqis tes ua rau engineers thiab technical neeg ua haujlwm. Kev nruj me ntsis raws li tus ntsuj plig thiab tsab ntawv ntawm cov ntaub ntawv sau tseg yog kev lees paub ntawm cov khoom siv.
Nyob hauv peb lub teb chaws, muaj qhov kev loj hlob meej meej hauv kev tsim kho ntau yam chaw. Lawv dav siv pob zeb thiab pob zeb ua vaj tse. SNiP tso cai rau lub xeev ntawm cov xwm txheej no, raug siv los ntawm cov khoom siv raw khoom zoo thiab ua raws li cov txheej txheem thev naus laus zis.
