Utilization method of waste stone
The invention discloses a utilization method of waste stone. Waste rock samples generated in a river excavation process is crushed, mixed with surface soil, and recycled, so that the physical and mechanical properties of the surface soil of the original river are improved, and the improved soil samples are used as river embankment filling materials. The environment problem caused by waste stone stacking and the engineering problem caused by poor soil property can be solved. When the fine powder obtained by crushing weathered sandstone is used for improving expansive soil, the expansive characteristic of the expansive soil can be remarkably reduced, the environmental problem caused by piling of waste stones and the engineering problem caused by water absorption expansion, water loss shrinkage and repeated expansion and shrinkage deformation characteristics of the expansive soil can be solved, the engineering cost can be saved, and good economic benefits can be obtained.
本发明公开了一种废弃石料的利用方法，采用将河道开挖过程中所产生的的废弃岩样进行破碎后，与表层土壤进行混合再利用的方法，改善原河道表层土壤的物理力学性质，改良后的土样用作于河道堤岸填筑材料，不仅可以解决废弃石料堆砌引起的环境问题以及土壤性质较差引起的工程问题。风化砂岩粉碎的细粉在用于改良膨胀土，能显著降低膨胀土的膨胀特性，不仅可以解决废弃石料堆砌引起的环境问题以及膨胀土吸水膨胀、失水收缩、反复胀缩变形特性引起的工程问题，又能节省工程造价，取得良好的经济效益。
