Yam dab tsi cuam tshuam txog kev sib cog lus ntawm Txoj Kev Roller?

1. Yam khoom siv
1. Lub zog muaj zog
Lub zog excitation ntawm Txoj Kev Cov Menyuam Yaus yog ib qho ntawm cov tseem ceeb cuam tshuam rau cov nyhuv compaction. Qhov ntau dua qhov excitation quab yuam, lub zog muaj zog ntawm cov khoom siv hauv av thiab cov nyhuv compaction zoo dua. Feem ntau hais lus, lub zog excitation ntawm hnyav Txoj Kev Cov Menyuam Yaus yog qhov loj, uas yog tsim rau compacting thicker av txheej thiab cov ntaub ntawv uas muaj zog dua; lub zog excitation ntawm lub teeb Road Roller yog me me, uas yog tsim rau compacting nyias txheej thiab cov ntaub ntawv softer.
Piv txwv li, nyob rau hauv lub compaction ntawm txoj kev hauv paus, kev siv txoj kev Roller nrog loj excitation quab yuam yuav zoo dua compact cov ntaub ntawv xws li crushed pob zeb thiab gravel, thiab txhim kho lub zog thiab stability ntawm lub hauv paus.
2. Vibration zaus
Lub vibration zaus kuj yuav cuam tshuam cov nyhuv compaction. Kev vibration ntau dua tuaj yeem ua rau cov khoom siv vibrate ntau dua nyob rau lub sijhawm luv, ua kom yooj yim dua mus txog lub xeev ntom ntom. Txawm li cas los xij, qhov kev vibration siab dhau lawm yuav ua rau muaj kev co ntau dhau ntawm cov khoom siv, cuam tshuam rau qhov flatness.
Piv txwv li, rau cov xuab zeb nrog cov khoom me me, qhov kev vibration ntau dua tuaj yeem ua rau cov xuab zeb tuaj yeem ua tiav qhov khoob thiab txhim kho cov qib compaction; thaum rau av nplaum av, tsim nyog txo qhov kev vibration zaus yuav zam dhau adhesion ntawm cov av thiab txhim kho cov nyhuv compaction.
3. Ramming phaj loj thiab cov duab
Qhov luaj li cas thiab cov duab ntawm lub phaj ramming yuav cuam tshuam rau thaj chaw tiv tauj thiab kev faib siab nrog hauv av. Ib cheeb tsam loj dua ramming tuaj yeem npog thaj tsam loj dua hauv ib qho kev sib cog lus thiab txhim kho kev ua haujlwm; tab sis rau compaction nyob rau hauv qhov chaw nqaim, me me ramming phaj yog hloov tau ntau dua.
Ramming daim hlau ntawm cov duab sib txawv, xws li cov duab plaub thiab voj voog, kuj yuav muaj qee yam cuam tshuam rau cov nyhuv compaction. Piv txwv li, ib lub voj voog ramming feem ntau yuav tsim kom muaj kev sib faib siab thaum lub sij hawm compaction txheej txheem, uas yog haum rau lub sij hawm uas yuav tsum tau siab rau flatness.
2. Compacted khoom yam
1. Hom khoom
Cov khoom sib txawv muaj cov yam ntxwv sib txawv. Piv txwv li, xuab zeb hais yog xoob thiab yooj yim rau compact, tab sis particle sib cais yog nquag tshwm sim; av nplaum av muaj zog cohesion thiab nyuaj rau compact, tab sis muaj zoo stability tom qab compaction.
Rau cov ntaub ntawv xws li crushed pob zeb thiab gravel, cov nyhuv compaction ntawm Txoj Kev Cov Menyuam feem ntau yog nyob ntawm qhov gradation thiab particle loj faib ntawm cov khoom. Cov ntaub ntawv zoo-qib tau yooj yim dua rau kev cog lus, thaum cov khoom uas loj dhau los yog me me tuaj yeem cuam tshuam cov nyhuv compaction.
2. Cov khoom siv noo noo
Cov dej noo ntawm cov khoom yog qhov tseem ceeb rau cov nyhuv compaction. Thaum cov ntsiab lus noo noo siab dhau lawm, kev sib txhuam ntawm cov khoom siv yog txo, thiab lub siab ntawm Txoj Kev Cov Menyuam Yaus nyuaj ua rau cov khoom ntom ntom; Thaum cov ntsiab lus noo noo tsawg dhau, lub zog sib txuas ntawm cov khoom siv tsis txaus, thiab nws nyuaj rau ua tiav cov nyhuv compaction zoo.
Txhua yam khoom muaj qhov pom zoo ntawm cov dej noo noo ntau, thiab kev cog qoob loo hauv qhov ntau no tuaj yeem ua tiav cov txiaj ntsig zoo tshaj plaws. Piv txwv li, rau av nplaum, qhov zoo tshaj plaws noo noo cov ntsiab lus feem ntau nyob ze ntawm cov yas txwv; rau cov xuab zeb, qhov pom zoo noo noo cov ntsiab lus yog qhov tsawg.
3. Khoom txheej thickness
Cov txheej tuab ntawm cov khoom siv compacted yuav cuam tshuam cov nyhuv compaction ntawm Txoj Kev Roller. Yog hais tias cov txheej thickness loj dhau lawm, lub zog txaus siab ntawm Txoj Kev Roller yuav tsis tuaj yeem nkag mus rau tag nrho cov av txheej, uas ua rau tsis txaus compaction ntawm cov txheej hauv qab; Yog hais tias cov txheej thickness me me dhau lawm, nws yuav ua rau over-compaction, cuam tshuam cov qauv stability ntawm cov khoom.
Feem ntau hais lus, Txoj Kev Cov Menyuam Yaus yog tsim rau compacting cov ntaub ntawv txheej nrog ib tug tej yam thickness ntau. Qhov tshwj xeeb compaction thickness yuav tsum tau txiav txim siab raws li tus qauv ntawm Txoj Kev Cov Menyuam, lub zog zoo siab thiab cov khoom ntawm cov khoom siv compacted.
3. Cov yam ntxwv ua haujlwm
1. Kev ceev ceev
Txoj kev mus los ntawm Txoj Kev Roller muaj qhov cuam tshuam ncaj qha rau cov nyhuv compaction. Yog tias qhov kev mus los nrawm dhau, lub phaj tamping yuav tsis muaj sijhawm txaus los ua hauv av thiab cov khoom siv tsis tuaj yeem ua kom tiav; Yog hais tias qhov kev mus los yog qeeb heev, txawm tias lub sijhawm compaction tuaj yeem nce ntxiv, kev ua haujlwm yuav raug txo.
Tus neeg teb xov tooj yuav tsum xaiv qhov tsim nyog mus txawv tebchaws raws li cov khoom thiab thickness ntawm cov khoom compacted. Feem ntau hais lus, rau cov ntaub ntawv nyuaj thiab cov av tuab dua, qhov kev mus los nrawm tuaj yeem tsim nyog ntxiv; rau cov ntaub ntawv softer thiab thinner av txheej, kev mus los yuav tsum tau qeeb.
2. Compaction hla
Tus naj npawb ntawm compaction hla yog ib qho tseem ceeb cuam tshuam rau cov nyhuv compaction. Nyob rau hauv ib txwm muaj xwm txheej, nce tus naj npawb ntawm kev sib cog lus tuaj yeem txhim kho qhov ntom ntawm cov khoom, tab sis ntau dhau kev sib cog lus yuav ua rau cov khoom dhau-compacted thiab rhuav tshem cov qauv kev ruaj ntseg ntawm cov khoom.
Rau cov khoom sib txawv thiab cov kev xav tau sib txawv, nws yog ib qho tsim nyog los txiav txim siab qhov tsim nyog tus naj npawb ntawm compaction dhau los ntawm kev sim. Feem ntau hais lus, thaum compacting, koj tuaj yeem ua ntej ua ib qho me me ntawm kev sib cog lus, tom qab ntawd xyuas cov nyhuv compaction, thiab maj mam nce tus naj npawb ntawm compaction dhau raws li xav tau.
3. Kev txawj ua haujlwm
Tus neeg teb xov tooj cov txheej txheem thiab kev ua haujlwm kev txawj ntse yuav cuam tshuam rau cov nyhuv compaction. Txoj kev ua haujlwm kom raug suav nrog thawb Txoj Kev Cov Menyuam kom du, zam kev tig ntse thiab nres nres, thiab ua kom lub phaj tamping ntsug rau hauv av.
Tsis tas li ntawd, tus neeg teb xov tooj yuav tsum tau ua tib zoo saib xyuas cov nyhuv compaction thiab kho cov kev khiav hauj lwm tsis nyob rau hauv lub sij hawm, xws li taug kev ceev, compaction passes, thiab lwm yam, los xyuas kom meej qhov zoo tshaj plaws compaction nyhuv.
