摘要
根据产生阶段和设计强度对铁路工程废弃混凝土进行了分类,分析了铁路工程废弃混凝土的特点,介绍了其在路基填筑和边坡防护中的应用情况,并以废弃混凝土再生粗骨料和再生砂粉为例,阐述了铁路工程废弃混凝土的研究、应用现状以及优化方法。最后指出了铁路工程废弃混凝土再利用存在的问题,建议构建铁路废弃混凝土再利用技术标准体系、铁路工程废弃混凝土的智慧管控平台,以实现废弃混凝土的规范化、多途径、高质化利用。
According to the generation stage and design strength,the waste concrete in railway engineering was classified,the characteristics of waste concrete in railway engineering were analyzed,and its application in subgrade filling and slope protection was introduced.Taking recycled coarse aggregate and recycled sand powder of waste concrete as examples,the research,application state and optimization methods of waste concrete in railway engineering were described.Finally,the problems existing in the reuse of waste concrete in railway engineering were pointed out.It is suggested to establish a technical standard system for the reuse of railway waste concrete and an intelligent control platform for waste concrete in railway engineering,so as to realize the standardized,multi-channel and high-quality utilization of waste concrete.
