Tam sim no cov vuas qub tau muaj kev ywj pheej los ntawm ntau tus neeg hauv cov ntaub ntawv ua lag luam hauv tsev thiab muaj qhov nrov tshaj plaws. Ntawm no, peb txoj kev ua haujlwm qub txeeg qub teg cov chaw tsim khoom lag luam yuav qhia koj rau qhov kev paub no. Cov xim ntawm lub cib yog ze rau cov txheej txheem tua hluav taws. Lub antique pem teb nplais pob zeb muaj huab cua huab cua tiv thaiv thiab xim durability. Antique cov vuas siv huab cua {{4 4}} istantant engineering polyester ua cov nplais deg. Cov kav antique pem teb nplais pwm muaj cov tshuaj tiv thaiv corrosion zoo heev. Antique cov vuas luaj yuav tsis yauv los nag thiab daus, tuaj yeem tiv thaiv alkali thiab discolor, thiab ntau cov kab mob tsis tuaj yeem muaj sia nyob ntawm cov nplais. Nyob rau tib lub sijhawm, nws yooj yim mus nqa thiab txua, txuag kev thauj khoom, txo cov nqi kev tsim kho, thiab txhim kho cov avquake tsis kam. Muaj plaub tus yam ntxwv yooj yim ntawm lub tuam tsev txheej thaum ub ua haujlwm hauv av pwm. Lub tuam tsev txheej thaum ub ua si pwm pwm muaj cov tsos zoo nkauj thiab lub teeb zoo. Lub tuam tsev thaum ub ua ke pwm siv cov ntaub pua rooj fiberglass ci ntsa iab Nws yog qhov haum rau kev txhim kho qub txhim kho thiab thaj chaw huv, nrog rau cov chaw ua haujlwm tshiab thiab qub thiab qub txeeg qub teg hauv cov vaj tse scenic.
Thaum dej nag zoo pwm tau thauj mus rau lub chaw tsim kho, cov neeg ua haujlwm ntau lawm yuav muab cov khoom siv hauv sab hauv thiab sab nraud, cov pob zeb ua haujlwm, ua ntej pouring. Lub pouring ntawm cov xis mas tseem yuav nrog los ntawm kev co ntawm cov pas nrig vibrating. Cov kev ntsuas no nce cov adhesion thiab kev ntseeg siab ntawm cov cement ntawm cov prefabricated ntu, yog li txhim kho kev ruaj ntawm cov prefabricated feem. Tom qab lub hnab ntim pwm tseem ua tiav, cov hlau tuav yuav welded raws li cov kev xav tau tiag tiag. Lub zuag qhia tag nrho yog transverse hlau cov kab thiab cov hlau ntev hlau. Lub pob zeb sab nraud yog nyob sab nraud thiab sab hauv cov pob zeb sab hauv yog sab hauv. Qhov tseem ceeb ntawm cov tav phaj tseem yuav nce cov compressive tag nrho cov compressive tiv thaiv cov pwm. Lub caij dej nag tau muaj feem ntau ua los ntawm cov phiaj hlau. Cov phiaj hlau hlau yuav tsum yog cov phiaj tsim qauv hlau tau tshawb xyuas los ntawm cov chaw haujlwm hauv tebchaws. Qhov no qhia yog vim li cas paub cov pwm ua kom loj hlob yog xaiv, nrog ntau cov qauv paub tab thiab nruj nruj kev tshuaj xyuas kev kuaj xyuas. Txuas ntxiv nrog cov phaj steel, cov phaj steel muaj qhov ntom ntom, tawv tawv, thiab muaj peev xwm tiv taus cov siab coj los ntawm cov qhob. Nws tseem yog lub hauv paus rau kom ua rau muaj kev ruaj khov ntawm cov khoom ua ntej. Yuav ua li cas kom ntseeg tau tias prefabricated tshooj thaum kev tsim khoom thiab kev siv cov khoom siv los nag ua cov pwm? Qhob dej nag ua pwm zoo yog cov hlau loj pwm. Dej nag zoo prefabricated seem yog siv nyob hauv av thiab siv nyob rau hauv av thawm xyoo. Yog li ntawd, qhov kev ruaj khov ntawm prefabricated qhov chaw tsis tsuas yog qhia txog qhov chaw ua ntej, tab sis tseem ceeb tshaj plaws, ua rau kev nyab xeeb ntawm kev nyab xeeb ntawm cov neeg saib xyuas kev nyab xeeb.
