Compaction machinery muaj cov tshuab txav hauv av uas siv cov cuab yeej siv dag zog los ua kom cov txheej txheem ntim cov av, pob zeb, thiab cov ntaub ntawv zoo sib xws. Cov tshuab no tau siv dav hauv kev tsim kho cov haujlwm uas muaj cov hauv paus, txoj kev, tshav dav hlau, dams, thiab lwm yam qauv.
Raws li lawv cov qauv kev khiav hauj lwm, cov tshuab compaction tau muab faib ua ntau hom: static dov (uas tam sim no tau hloov los ntawm ntau txoj hauv kev), kev cuam tshuam, vibratory, thiab ua ke - hom kev ua. Static rollers ua tiav compaction los ntawm leveraging qhov hnyav gravitational ntawm lawv cov menyuam; vibratory rollers induce mus tas li deformation thiab densification nyob rau hauv lub compacted txheej los ntawm kev co; thiab cuam tshuam cov menyuam ua tiav kev sib dhos los ntawm kev sib xyaw ua ke ntawm dov thiab kev cuam tshuam quab yuam. Cov rollers lawv tus kheej tau muab faib ua ntau hom: du - log, grooved, sheepsfoot, thiab pneumatic - log tsheb. Grooved thiab sheepsfoot rollers exert siab chav tsev siab thiab muaj peev xwm ntawm compacting thicker txheej, ua rau lawv tshwj xeeb tshaj yog haum rau lub compaction ntawm roadbeds thiab dams. Pneumatic- cov log tsheb muaj cov log tsheb uas tuaj yeem hloov tau thiab qhov hnyav tuaj yeem sib txawv, tso cai rau kev tswj tau yooj yim ntawm chav tsev siab; Tsis tas li ntawd, lub kneading txiav txim uas tsim thaum lub sij hawm compaction kom ib tug uniform thiab ntom compacted txheej. Qhov no ua rau lawv zoo tagnrho rau compacting puag txheej hauv txoj kev, pej xeem squares, thiab cov chaw zoo sib xws, raws li lawv zoo compact cov ntaub ntawv uas tsis ua puas lub pavement nto.
