Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm txoj kev roller
Txoj kev rollers yog qhov tseem ceeb hauv kev tsim kho vaj tse, los ntawm txoj kev loj mus rau qhov chaw nres tsheb. Lawv lub luag haujlwm tseem ceeb yog ua kom cov av sib xyaw, asphalt, lossis pob zeb, tshem tawm cov pa tawm thiab txhim kho kev thauj khoom -cov kabmob muaj peev xwm. Kev nkag siab txog lawv txoj haujlwm ua haujlwm pab cov engineers, cov neeg ua haujlwm tsim kho, thiab txawm tias cov neeg nyeem xav paub txog vim li cas cov tshuab hnyav no tseem ceeb heev rau cov pavements ruaj khov.
Core Structure: Lub Foundation ntawm Compaction
Ib txoj kev raug rau cov menyuam muaj peb yam tseem ceeb:
1.Roller Nruas: Lub cylindrical steel nruas (ib zaug lossis ob npaug) yog qhov chaw sib cuag nrog qhov chaw. Nws qhov hnyav (nrog rau 1 txog 20 tons) muab thawj zaug compaction quab yuam
2.Power System: Diesel cav tsav lub nruas kev sib hloov thiab lub tshuab txav, ua kom lub siab zoo ib yam.
3.Control Vaj Huam Sib Luag: Cov neeg ua haujlwm kho qhov ceev (2-5 km / h rau kev pom kev compaction) thiab nruas vibration ntawm intuitive tswj.
Mechanism ua hauj lwm: Siab + vibration=Zoo meej Compaction
Lub hauv paus ntsiab lus ua haujlwm yog nyob ntawm ob lub zog ntxiv:
1.Static Pressure: Lub nruas qhov hnyav tuag nias rau ntawm cov khoom, nyem cua thiab dej tawm. Piv txwv li, 10-tuj cov menyuam siv 200 kPa ntawm lub siab ntawm asphalt, yuam cov khoom kom cuam tshuam.
2.Vibrational Force: Feem ntau cov menyuam niaj hnub no muaj cov vibrating nruas. Internal eccentric ncej tig ntawm 2,000-3,600 RPM, ua kom muaj kev vibrations siab (50-60 Hz). Cov kev vibrations txo cov khoom sib txhuam, tso cai rau cov khoom kom rov ua dua rau hauv cov qauv denser
Cov Txheej Txheem Tseem Ceeb: Ua kom muaj txiaj ntsig thiab Precision
1.Vibration Control System: Kho kev vibration amplitude (0.3-}1.5 mm) raws li cov khoom siv-softer av xav tau ntau dua amplitude, thaum asphalt yuav tsum tau softer vibrations kom tsis txhob tawg.
2.Steering System: Articulated steering tso cai rau cov menyuam taug kev nkhaus yam tsis muaj kev puas tsuaj rau qhov chaw compacted, ua kom muaj kev sib haum xeeb thoob plaws qhov dav.
3. Dej Txau System: Tiv thaiv asphalt los ntawm kev lo rau lub nruas, tswj kom du compaction.
Vim Li Cas Nws Tseem Ceeb: Durability thiab Kev Nyab Xeeb
Kev cog lus kom raug los ntawm txoj kev cov menyuam yaus txuas ntxiv kev ua neej nyob ntawm 30-50% thiab txo cov nqi kho. Nws tseem tiv thaiv cov poholes thiab qhov chaw tsis sib xws, txhim kho kev nyab xeeb ntawm kev tsav tsheb. Rau cov pab pawg tsim kho, nkag siab txog txoj hauv kev ua haujlwm kom pom kev siv tshuab, txuag sijhawm thiab peev txheej
