高等级公路及大型建筑设施等需要对地基进行稳定处理,即将土壤破碎为粉状和小颗粒状,然后与石灰等添加剂混合均匀碾压密实;在一些油气管道、桥涵、大型水渠等回填施工中需要使用经过破碎为均匀小颗粒的土壤进行填充;土壤破碎已成为现代工程施工中一个重要的工艺环节。由于土壤中可能包含有石块、砖块等坚硬材料,可能因含水量偏高而发粘,并且生产率要求高(每小 High-grade highways and large-scale construction facilities need to stabilize the foundation, that is, crushing the soil into powder and small particles, then mixing with additives such as lime, and rolling evenly; in some oil and gas pipelines, bridges and culverts, large ditches and other backfill construction It needs to be filled with soil that has been crushed into uniform small particles. Soil crushing has become an important process in modern engineering. Due to the soil may contain hard materials such as stones, bricks, etc. may be sticky due to high moisture content, and high productivity (small
