大庆乙烯工程晴纶厂毛绦车间建在厚1m的回填土上,面积1万m。因土壤含水量过大,地耐力不足,采用小口径生石灰桩进行地基加固,取得了降低造价和提高工效的良好效果。加固区内地基土干容重为1.0～1.1g/cm~3,含水量35%左右。为可塑性粘土。使用HZb—60型普通振捣棒扩孔,在人行通道扩孔时,在土硬壳挖掉后 Daqing Ethylene Acrylic Factory Maopi workshop was built on a 1m thick backfill with an area of ​​10,000 m. Due to the excessive soil moisture content and lack of endurance, the use of small-caliber quick-lime piles for ground reinforcement has achieved good results in reducing the cost and improving the work efficiency. The dry weight of the foundation soil in the consolidation zone is 1.0 to 1.1 g/cm 3 and the water content is about 35%. Plastic clay. Use HZb-60 type vibrating rod reaming hole, when reaming in the pedestrian passage, after digging off the hard shell
