Rau kev cog qoob loo ntawm cov av thaum lub sijhawm tsim kho lossis kev ua haujlwm hauv kev tsim kho vaj tse, siv rammer. Compaction tshwm sim vim lub caij nplooj zeeg ntawm lub platform ua haujlwm, uas tuaj yeem muaj cov duab sib txawv (daim duab plaub, lub voj voog lossis square). Nyob ntawm tus qauv tsim, rammer tuaj yeem ua tau ntau yam.
-
tamping tshuab Sibtham nrog lub caij nplooj zeeg dawb ntawm cov slab, uas yog nqa los ntawm lub cam lossis khib tsav lossis hlua txoj hlua. Qhov no yog pab pawg ua haujlwm qis tshaj plaws: qhov zaus ntawm kev poob qis yog li 10 strokes / min.
- Explosive Rammer yog siv los ntawm cov roj hlawv.
- Auto-tamping units ua haujlwm los ntawm kev siv lub cam lossis crank mechanism uas rov qab thauj khoom mus rau nws txoj haujlwm qub.
- Pneumatic rammer siv cov cua compressed los nqa cov slab. Tus nqi poob siab tshaj plaws yog kwv yees li 1000 strokes / min.
Raws li qhov cuam tshuam lub zog, cov txheej txheem no tau muab faib ua peb pawg.
- Hnyav muaj kev cuam tshuam lub zog ntawm 1000 txog 5000 kg / m (50,000 J).
- Medium - ntaus100-1000 kg/m (1000-10,000 J).
- Lub ntsws ua rau hauv av nrog lub zog ntawm 80-100 kg / m (txog 1000 J).
Hnyav rammer feem ntau yog tsheb laij teb-mounted, qhov hnyav ntawm lub platform ua haujlwm tuaj yeem ncav cuag 3 tons, thiab qhov siab los ntawm qhov nws ntog mus txog 2.5 meters. Qhov cuam tshuam zaus ntawm hom tshuab no tsawg.
Tshuab ntawm cov chav nruab nrab yog tsim los ntawm tus kheej-propelled chassis lossis hauv daim ntawv ntawm cov khoom siv tsheb laij teb. Muaj cov kev xaiv rau tus kheej hauv pawg no. Lub teeb rammers yog lub teeb hauv qhov hnyav thiab ua haujlwm manually. Cov qauv tshaj plaws hauv pab pawg no yog roj av. Qhov me me thiab kev ua haujlwm yooj yim tso cai rau lawv siv rau hauv qhov chaw nkag tsis tau rau lwm yam khoom siv.
Muaj ob hom rammers raws li txoj kev hloov lub zog rau hauv av: nrog lossis tsis muaj chabot. Chabot - ib lub phaj hlau muab tso rau hauv av, uas ntog rau ntawm qhov chaw ua haujlwm. Cov cav ntoo ncej muaj kev ua haujlwm tsawg, dhau li ntawd, muaj peev xwm ntawm cov phaj tawg, vim tias cov tshuab no feem ntau muaj lub zog qis.
Asph alt paving, av compaction hauv kev tsim kho lossis kev tsim kho vaj tse, paving slab nteg thiab ntau lwm txoj haujlwm yog thaj chaw uas siv tau rammer. Tus nqi nyob ntawm lub zog ntawm chav tsev, hom cav, version thiab cov chaw tsim khoom. Tus nqi sib kis yog qhov tseem ceeb txawm tias nyob hauv chav kawm lub teeb: chav tsev pheej yig tshaj plaws tuaj yeem yuav tau rau $ 600-700, tus neeg sawv cev kim tshaj plaws ntawm lub tshuab hom no raug nqi $ 13,000-15,000.
Nws tsim nyog xav txog kev yuav khoom "rammer" yog tias chav tsev yuav tsum tau siv tas li, tab sis yog tias kev siv yog ntu ntu, ces koj tuaj yeem siv cov kev pab xauj tsev ntawm cov khoom siv. Muaj cov koom haum uas muab kev qiv ntawm rammer rau tus nqi. Ua ntej nrhiav cov chav kawm thiab lub peev xwm ntawm cov cuab yeej tsim nyog, npaj lub xaib rau kev ua haujlwm thiab pib tshawb nrhiav cov khoom tsim nyog. Tus nqi xauj tsev ntawm cov cuab yeej siv yog xam raws li lub sij hawm uas chav tsev muab rau koj thiab nws cov nqi.
