Terrace backfill, outdoor sports backfill smooth etc..It needs to be compacted after backfilling of earthwork, debulking methods generally have rolled-on method, compacting method, vibration
Dynamic compacting utilizes earth moving tool debulking methods.For large-area fill-back earth engineering, mostly uses and roll and utilize earth moving tool pressure
It is real, for the fill construction compared with small area, then preferably it is compacted with compacting tool.
Vibrating compacting equipment quickly transmits a series of bumps to surface, and the pressure wave of generation, which is transmitted to filler, makes particle
Movement is more next, reduces or almost eliminates the internal friction between particle, particle is allowed more closely to rearrange, contact point between particle
People increases so that bearing capacity enhances, and vibrating compacting has a great impact for coarse-grained soil, although influencing for particulate filler
It less, but still is most effective in compactor.For all packing materials, vibrating compacting reaches than quiet compactioncan
Higher compactness and better compacting depth, need to only roll several times can reach final compactness.
Large-scale vibrating compacting equipment is mainly vibrated roller, is suitable for large-area fill-back earth engineering, and equipment at
This is higher.Small vibrating compacting equipment mainly has vibratory plate compactor, and just it rolls that area is small, and working efficiency is low.
