白沙快速出口路土石方综合利用的探讨

Comprehensive Utilization of Earthwork in Baisha Express Exit Road

以白沙快速出口路工程为例,探讨土石方的综合利用。通过实验室检测,将符合行业标准的隧道出渣加工成机制砂,弥补工程原料不足;将工程开挖的软土用于回填废弃鱼塘,改造为林地和农田;将不满足路用条件的弃渣用于填埋废弃矿坑。通过上述措施有效利用土石方,减少新增占地。

Taking Baisha expressway project as an example,this paper discusses the comprehensive utilization of earthwork.Through laboratory testing,the tunnel slag that meets the industry standard is processed into machine-made sand to make up for the shortage of engineering raw materials.The soft soil excavated by the project is used to backfill abandoned fish ponds and transform them into woodland and farmland;waste slag that does not meet the road conditions is used to fill abandoned mines;through the above measures,the earthwork can be effectively used to reduce the newly-added land occupation.
