Hauv cov txheej txheem ntawm kev tsim kho vaj tsev, pob zeb ua kev tso dej yuav tsum tau muaj ntau ntawm cov qauv tsev. Daim ntawv ua haujlwm tsim ua feem ntau suav txog 20% -30% ntawm tus nqi ntawm cov haujlwm pob zeb pob zeb tsim, 30% -40% ntawm kev ua haujlwm ntawm engineering, thiab kwv yees li 50% ntawm lub sijhawm tsim kho. Formwork technology cuam tshuam ncaj qha rau kev tsim kho qhov zoo, nqi thiab txiaj ntsig ntawm txoj haujlwm.
Cov tshuaj polypropylene cob yog siv los ua cov khoom siv hauv paus, uas tsis muaj ntxhiab, tsis muaj tshuaj lom thiab tsis muaj kuab lom, thiab tsis tsim cov tshuaj lom thiab tsis phom sij thaum siv. Kev ua haujlwm txias, tiv tshav kub, nthuav dav coefficient, tsis muaj shrinkage, tsis dampness, tsis muaj tawg, tsis muaj deformation, zoo heev ua tau zoo.
Nws yog 8-10 zaug siv tau ntev dua li cov qauv ntawv sib xws, pes tsawg zaus ntawm lub dav hlau pwm siv tsis yog tsawg dua 50 zaug, pes tsawg zaus ntawm kab ntawv ncej pwm siv tau tsis yog tsawg dua 65 npaug, qhov nruab nrab ntawm lub voj voog siv pua pua lub sijhawm, thiab nws tuaj yeem siv nrog ntoo plywood, xyoob plywood thiab lwm yam khoom siv Sib xyaw ntawm daim hlau.
Nws tuaj yeem raug xauj nyob ib ntus lossis siv rau kev siv sijhawm ntev. Tsis yog tsuas yog muaj coob tus ntawm kev hloov pauv, tab sis cov qauv siv kuj tseem tuaj yeem ua kom zoo nyiaj rov qab. Qhov nruab nrab ntawm kev siv ntawm ib qho qauv yog tsawg dua ib qho yuan, uas ua kom muaj kev siv nyiaj siab tshaj plaws ntawm kev sib raug zoo thiab txhawb kev nthuav dav kev lag luam.
Lub hollow yog lub teeb thiab yooj yim nqa, thiab muaj lub zog yoog raws, uas tuaj yeem ua tau raws li cov kev xav tau ntawm lub tsev kev txhawb nqa rau ntau yam duab ntawm cov tsev. Ua tau zoo txhim kho kev tsim kho cov sij hawm thiab txuag lub sijhawm thiab nqi. Nruj ua ke raws li qhov loj me ntawm tus qauv nrog daim txiag pawg, tus qauv splicing yog nruj thiab du, tsis muaj qhov thib ob plastering yog qhov yuav tsum tau ua, cov dej ntsa ntshiab kom du thiab du, thiab ib-zaug molding txuag kev ua haujlwm thiab khoom siv. Tsis tas yuav pleev xim tus tso tawm ua ntej siv, thiab tus qauv raug muab tshem thaum qhov kev txhawb nqa tawm.
