The Luoyang Lutong LT210 series single steel drum vibratory roller is fitted with detachable padfoot modules and a standard smooth steel drum, delivering two working modes in one unit. It performs excellently for deep kneading compaction of cohesive soil as well as surface compaction of gravel and stabilized base materials. As high-efficiency core compaction equipment, it serves highway infrastructure, water conservancy works, industrial yard development and municipal projects to satisfy diverse compaction demands across different job sites.
1. Working Condition with Padfoot Drum Installed
Working Principle
The padfoot drum generates high localized contact pressure. Combined piercing, squeezing and kneading actions break soil clods, remove voids within cohesive soil and achieve consistent deep compaction. It addresses typical challenges faced by smooth drums when working on cohesive layers, such as slippage, springy soil and pumping.
Main Applications and Functions
Highway and Municipal Road Subgrade EngineeringIt handles layered filling and compaction for subgrades of national highways, provincial roads, urban arterial roads and park roads, especially sections filled with clay, silty soil and expansive soil. It boosts the compaction degree of lower subgrade layers, controls post-construction settlement and raises the overall bearing capacity and stability of road foundations.
Water Conservancy Dam and River Regulation ProjectsPerfect for earth filling compaction on earth dams, flood dykes, river embankments and canal bases. Its distinctive kneading action densifies cohesive fill, lowers the soil permeability coefficient and guarantees anti-seepage performance for hydraulic structures.
Landfill Site EngineeringUsed for base compaction and protective soil layer compaction at municipal solid waste landfills. It compacts foundation soil evenly, prevents differential settlement and protects the site’s anti-seepage membrane system.
Industrial Plant and Large Foundation ConstructionSuitable for backfill compaction at factories, warehouses, logistics parks and large storage yards. It increases deep foundation density, reduces ground cracking and settlement, and safeguards the structural safety of buildings to be built later.
2. Working Condition with Smooth Steel Drum (Padfoot Removed)
Once the detachable padfoot modules are taken off, the roller works as a standard smooth vibratory steel drum roller. It compacts materials via high-frequency vibration plus static weight and is mainly used for non-cohesive loose materials and fine surface compaction.
Core Advantage
One machine for dual purposes: freely switch between deep cohesive soil compaction and gravel surface compaction, cutting equipment investment while enhancing construction flexibility.
