摘要
高速公路改扩建工程中会有大量的结构物拆除并产生大量的废旧圬工材料,为此分析了废旧圬工材料直接废弃的危害。根据其形状和尺寸、强度等,将废旧圬工材料分为废旧片石、块石、预制块以及圬工渣等4种类型。针对废旧圬工材料的特点,研究提出了合理利用废旧圬工材料的集中利用原则、降级使用原则、强度等级原则、圬工渣利用原则和废旧预制块利用原则。进而分析了在公路工程中废旧圬工材料利用的多种方式。
A large number of structures were demolished in the highway expansion project,thus results in a lot of discarding masonry materials. In order to analyze the hazard of discarding masonry materials,they are divided into four types according to its shape and size,i. e. rubble,stone,precast block and slag. According to its types and characteristics,six reasonable principles to recycle masonry materials are proposed,i. e. centralized utilization principle,degraded utilization principle,strength classification principle,slag utilization principle,and precast block utilization principle. And then,several approaches to recycle masonry material in highway engineering are put forward.
