Dab tsi yog qhov txawv ntawm cov nyhuv compaction ntawm cov log tsheb thiab steel log rollers?

1. Compaction qhov tob:
Tire roller: Lub log tsheb ntawm lub log tsheb muaj qhov elasticity. Thaum lub sij hawm compaction txheej txheem, qhov chaw sib cuag ntawm lub log tsheb thiab hauv av yog loj, thiab lub siab tis yog sib xws. Qhov no ua rau nws tsim cov nyhuv compaction ntau dua ntawm txoj kev cov khoom siv nyob rau hauv lub siab me me, thiaj li ua tiav qhov sib sib zog nqus qhov tob. Feem ntau hais lus, qhov tob tob ntawm lub log tsheb tuaj yeem ncav cuag li 20-30 cm.
Steel log rau cov menyuam: Lub compaction log ntawm steel log rau cov menyuam yog ua los ntawm cov hlau, uas muaj ib tug ntau dua hardness thiab ib tug kuj me me cheeb tsam nrog rau hauv av. Thaum lub sij hawm cov txheej txheem compaction, cov hlau log rau cov menyuam feem ntau yog nyob ntawm nws tus kheej qhov hnyav thiab kev co lub zog los ua kom cov khoom siv ntawm txoj kev. Vim lub hardness ntau dua ntawm cov hlau log, nws qhov tob compaction yog qhov ntiav, feem ntau nyob ib ncig ntawm 15-20 cm.
2. Compaction uniformity:
Cov log tsheb: Vim lub elastic deformation ntawm lub log tsheb, lub log tsheb cov menyuam tuaj yeem hloov kho kom zoo dua rau qhov tsis sib xws ntawm txoj kev thaum lub sij hawm compaction txheej txheem, ua rau lub siab tis ntawm txoj kev nto zoo sib xws. Qhov no yuav pab txhim kho qhov flatness thiab compaction zoo ntawm txoj kev nto thiab txo qhov tsis sib haum ntawm txoj kev nto.
Steel log rau cov menyuam: Lub log steel nto ntawm cov hlau log rau cov menyuam yog tus du, thiab lub zog siab hauv zos yog nquag tshwm sim thaum lub sij hawm compaction, uas ua rau tsis sib xws. Tshwj xeeb tshaj yog thaum compacting txoj kev tsis sib xws, steel log chais yuav ua rau kom siab dua ntawm convex los yog concave qhov chaw, thaum lub compaction nyhuv ntawm lwm qhov chaw kuj tsis zoo. Txhawm rau txhim kho qhov sib npaug ntawm qhov sib npaug, steel log rollers feem ntau yuav tsum tau nruab nrog cov tshuab vibration siab heev thiab tsis siv neeg qib.
3. Zoo ntawm txoj kev nto tom qab compaction:
Tire roller: Thaum lub sij hawm compaction txheej txheem, lub log tsheb cov menyuam tuaj yeem ua rau kev sib koom ua ke ntawm cov khoom ntawm txoj kev cov khoom siv ntau dua thiab tsim cov qauv ruaj khov dua vim qhov cuam tshuam ntawm lub log tsheb. Qhov no pab txhim kho cov kabmob muaj peev xwm thiab kav ntev ntawm txoj kev nto thiab txo cov kab nrib pleb thiab deformation ntawm txoj kev nto. Tsis tas li ntawd, qhov chaw ntawm txoj kev nto compacted los ntawm cov log tsheb cov menyuam yog qhov tiaj tus thiab qhov roughness yog nruab nrab, uas yog qhov tsim nyog rau kev txhim kho kev ua haujlwm ntawm kev sib tsoo thiab kev tsav tsheb ntawm txoj kev nto.
Steel log roller: Qhov saum npoo ntawm txoj kev nto compacted los ntawm cov hlau log rau cov menyuam yog tus du thiab muaj qhov roughness tsawg. Qhov no tej zaum yuav tsis zoo rau qee qhov kev taug kev uas yuav tsum tau ua kom muaj kev sib tw ntau dua (xws li txoj kev roob, txoj kev loj, thiab lwm yam). Tsis tas li ntawd, yog tias qhov kev vibration tsis zoo ntawm cov hlau log rau cov menyuam tsis tau teeb tsa kom zoo thaum lub sij hawm compaction, nws yuav ua rau cov ntaub ntawv pavement over-compacted, ua rau cov pavement nyuaj heev, yog li cuam tshuam rau qhov yooj thiab qaug zog ntawm txoj kev pavement.
4. Cov khoom siv pavement:
Tire rollers: Cov log tsheb yog tsim rau compacting ntau hom pavement cov ntaub ntawv, xws li av nplaum av, xuab zeb, gravel, asphalt sib tov, thiab lwm yam. Vim hais tias lub compaction qhov tob ntawm lub log log yog loj thiab tuaj yeem hloov mus rau cov yam ntxwv ntawm cov khoom sib txawv, lawv tau ua. dav siv nyob rau hauv kev tsim kho thiab tu. Tshwj xeeb tshaj yog rau qee cov ntaub ntawv softer pavement (xws li av nplaum), cov nyhuv compaction ntawm cov log tsheb yog qhov tseem ceeb dua.
Steel log rollers: steel log rollers yog tsim nyog rau compacting pavement cov ntaub ntawv uas muaj zog dua, xws li pob zeb, pob zeb, thiab lwm yam. Vim hais tias cov hlau log ntawm steel log rollers muaj ib tug hardness ntau dua, nws muaj peev xwm ua kom muaj zog ntau dua ntawm cov ntaub ntawv, yog li ntawd. ua tiav cov nyhuv compaction zoo dua. Tsis tas li ntawd, steel log rollers kuj muaj qee qhov zoo thaum compacting asphalt pavement, uas tuaj yeem ua rau asphalt sib tov ntau dua thiab txhim kho lub tiaj tus thiab durability ntawm pavement.
5. Kev cuam tshuam rau ib puag ncig ib puag ncig:
Tire roller: Thaum lub sijhawm ua haujlwm ntawm lub log tsheb, vim qhov elastic deformation ntawm lub log tsheb, qee lub suab nrov yuav raug tsim. Tsis tas li ntawd, kev sib txhuam ntawm lub log tsheb thiab hauv av kuj tseem yuav tsim cov hmoov av qee yam. Txhawm rau txo qhov cuam tshuam rau ib puag ncig ib puag ncig, cov log tsheb feem ntau yuav tsum tau nruab nrog cov silencers zoo thiab cov tshuab sprinkler.
Steel log rau cov menyuam: Thaum lub sijhawm ua haujlwm ntawm lub log steel, vim muaj kev sib txhuam ntawm lub log steel thiab hauv av, lub suab nrov yuav raug tsim tawm. Nyob rau tib lub sijhawm, cov hlau log rau cov menyuam kuj tseem yuav tsim cov hmoov av qee yam thaum lub sij hawm compaction. Txhawm rau txo cov kev cuam tshuam rau ib puag ncig, cov hlau log rau cov menyuam yuav tsum tau ua kom cov suab nrov txo thiab tiv thaiv plua plav, xws li kev txhim kho lub muffler thiab siv lub npog plua plav.
