浅谈对渗透性差的回填土增湿保证回填质量

土方工程 回填土 含水率 渗透性 增湿 旋耕机Abstract Earthwork construction soil moisture directly affects the size of compaction (RCC) quality. Such as soil permeability or range using conventionalmethods on soil humidity it is difficult to ensure the engineering quality and construction period and can cause a rise in engineering cost. Using rotary tillageof the soil after watering can make the soil material and the uniformity of water mixing in a short period of time ensure project quality and effectively shortenthe construction period.Keywords Earthwork backfill moisture content permeability humidification rotary cultivator
