Cov txheej txheem twg tuaj yeem siv los txheeb xyuas cov khoom faib ntawm cov paver?

1. Txoj kev soj ntsuam ncaj qha
1. Saib xyuas cov khoom nyob rau hauv lub hopper: Ua ntej lub paver yog tsim, xyuas seb cov khoom nyob rau hauv lub hopper yog tag nrho thiab tag nrho cov kev faib ntawm cov khoom. Yog hais tias cov khoom faib nyob rau hauv lub hopper yog pom tseeb tsis sib npaug, piv txwv li, muaj ntau cov ntaub ntawv nyob rau hauv ib sab thiab tsawg dua cov khoom nyob rau hauv lub sab, ces cov khoom faib yuav tsis sib xws thaum lub sij hawm paving txheej txheem. Nyob rau tib lub sijhawm, saib seb qhov luaj li cas, cov duab thiab cov av noo ntawm cov khoom tsis sib xws. Yog tias muaj qhov sib txawv loj, nws tseem yuav cuam tshuam rau cov khoom faib khoom tom qab paving.
2. Saib xyuas cov xwm txheej ua haujlwm ntawm tus xa khoom kauv: Thaum lub paver ua haujlwm, ua tib zoo saib qhov kev sib hloov ntawm cov kauv distributor kom pom tias nws ruaj khov thiab zoo ib yam. Yog hais tias tus kauv distributor co co, jams los yog tsis sib xws ceev thaum lub sij hawm tig, nws yuav ua rau cov khoom tsis sib npaug mus rau qhov chaw paving. Tsis tas li ntawd, xyuam xim rau qhov ntws ntawm cov ntaub ntawv ntawm cov khoom siv kauv kom pom tias cov khoom tuaj yeem ntws tawm sib npaug los ntawm txhua qhov chaw ntawm tus xa khoom. Yog tias pom tias cov khoom ntws tsis zoo los yog muaj ntau qhov sib txuam hauv qee qhov, thiab muaj cov khoom siv tsawg dua hauv lwm qhov, nws txhais tau tias cov khoom faib tsis sib xws.
3. Saib xyuas cov khoom tsub zuj zuj nyob rau hauv pem hauv ntej ntawm screed: Thaum cov khoom thauj mus rau lub screed los ntawm kauv feeder, soj ntsuam cov duab thiab qhov siab ntawm cov khoom tsub zuj zuj nyob rau hauv pem hauv ntej ntawm screed. Yog tias cov khoom sib xyaw ua ke qhia tau hais tias qhov siab ntawm ib sab thiab qis ib sab, siab hauv nruab nrab thiab qis ntawm ob sab, lossis lwm yam tsis sib xws, nws txhais tau hais tias muaj teeb meem nrog cov khoom faib. Nyob rau hauv ib txwm muaj xwm txheej, cov khoom yuav tsum tau sib npaug zos nyob rau hauv pem hauv ntej ntawm lub screed los ua ib tug kuj tiaj tus pawg.
4. Saib xyuas qhov kev faib khoom ntawm txoj kev paving tom qab paving: Tom qab paver tau paving ib qho kev ncua deb, saib xyuas qhov chaw ntawm pavement tom qab paving. Tshawb xyuas seb cov ntaub ntawv ntawm txoj kev taug kev puas tau muab faib sib npaug thiab seb puas muaj kev sib cais pom tseeb, xws li seb cov khoom sib xyaw ntxhib puas muaj nyob rau hauv qee qhov chaw thiab cov khoom sib xyaw zoo yog nyob rau hauv lwm qhov chaw. Nyob rau tib lub sijhawm, saib seb cov xim thiab kev ntxhib los mos ntawm cov pavement puas zoo ib yam thiab zoo ib yam. Yog tias muaj qhov sib txawv pom tseeb, nws kuj tseem tuaj yeem qhia txog kev faib khoom tsis sib xws.
2. Kev ntsuas ntsuas
1. Siv ib tug pas ntsuas los yog daim kab xev ntsuas los ntsuas cov khoom thickness: Ntawm lub pavement pavement, xaiv ob peb qhov chaw sib txawv thiab siv ib tug pas ntsuas los yog daim kab xev ntsuas los ntsuas cov khoom thickness. Thaum ntsuas, tus pas ntsuas lossis daim kab xev ntsuas yuav tsum tau muab tso rau ntawm txoj kab ntsug, thiab ntsuas cov ntsiab lus yuav tsum tau muab faib ua tusyees thoob plaws hauv thaj chaw paving, suav nrog cov npoo thiab nruab nrab ntawm txoj kev pavement. Los ntawm kev sib piv cov khoom tuab ntawm qhov chaw sib txawv, nws tuaj yeem txiav txim siab seb cov khoom faib khoom puas zoo ib yam. Yog tias cov khoom tuab ntawm qee qhov chaw muaj ntau dua lossis tsawg dua li ntawm lwm qhov chaw, nws qhia tau tias cov khoom faib tsis sib xws.
2. Siv cov metarly meterity meter ntawm cov khoom ntom ntom nti: kev kub ntxhov nuclear yog qhov ntsuas siv los ntsuas cov khoom siv ntom. Thaum lub sij hawm tsim kho ntawm lub paver, ib tug nuclear density meter yuav siv tau los ntsuas qhov ceev ntawm cov khoom tom qab paving. Thaum ntsuas, tso lub ntsuas hluav taws xob nuclear ntawm qhov chaw sib txawv ntawm txoj kev rau kev ntsuas raws li cov lus qhia ua haujlwm ntawm lub ntsuas. Los ntawm kev sib piv cov khoom ntom ntom ntawm qhov chaw sib txawv, qhov sib txawv ntawm cov khoom faib tuaj yeem nkag siab. Yog tias cov khoom siv ntom ntom hauv qee qhov chaw siab dua lossis qis dua li ntawm lwm qhov chaw, nws yuav qhia tau tias cov khoom faib hauv cheeb tsam ntawd tsis sib npaug.
3. Siv lub laser flatness meter los ntsuas qhov flatness ntawm txoj kev nto: lub laser flatness meter tuaj yeem ntsuas qhov flatness ntawm txoj kev sai thiab raug. Tom qab lub paving yog paving, siv lub laser flatness meter los ntsuas qhov paved txoj kev nto. Cov txiaj ntsig ntsuas tuaj yeem cuam tshuam qhov flatness ntawm txoj kev nto thiab tsis ncaj qha txiav txim siab seb cov khoom faib khoom puas zoo ib yam. Yog hais tias txoj kev nto tsis du thiab wavy los yog tsis sib xws, nws yuav yog vim tsis sib npaug ntawm cov ntaub ntawv, uas ua rau lub zog tsis sib xws ntawm screed.
3. Lwm txoj kev
1. Ntxiv cov cim rau cov khoom siv: Ntxiv qee cov cim qhia tau yooj yim rau cov khoom siv, xws li cov xim xim, cov hmoov fluorescent, thiab lwm yam. Thaum lub sij hawm paving txheej txheem, saib xyuas qhov kev faib ntawm cov cim rau ntawm txoj kev nto kom infer lub uniformity ntawm cov khoom faib. . Yog tias cov cim tau muab faib sib npaug ntawm txoj kev, nws txhais tau tias cov khoom faib khoom kuj tseem sib xws; conversely, yog hais tias cov cim yog concentrated nyob rau hauv tej qhov chaw los yog muaj pom tseeb uneven dispersion, nws txhais tau hais tias cov khoom faib yog uneven.
2. Txheeb xyuas cov ntaub ntawv kev tsim kho: Txheeb xyuas cov ntaub ntawv kev tsim kho ntawm paver, xws li paver's tsav ceev, ceev ntawm cov kauv feeder, qhov ceev ntawm cov saw hlau scraper thiab lwm yam tsis. Los ntawm kev txheeb xyuas kev sib raug zoo ntawm cov ntaub ntawv no thiab cov khoom faib khoom, nws txiav txim siab seb qhov kev faib khoom puas zoo ib yam. Piv txwv li, yog tias lub paver tus tsav tsheb nrawm nrawm hloov pauv thaum lub sijhawm tsim kho, thiab qhov ceev ntawm cov kauv feeder tsis raug kho raws li, nws yuav ua rau cov khoom tsis sib xws. Yog li ntawd, los ntawm kev saib xyuas thiab tshuaj xyuas cov ntaub ntawv tsim kho, qhov teeb meem ntawm kev faib khoom tsis sib xws tuaj yeem tshawb pom thiab daws tau raws sijhawm.
