【摘要】：近年来，城市化进程的加快使建筑垃圾产量呈陡增趋势。大量的建筑垃圾不仅破坏生态环境，侵占土地，而且造成了石料资源的浪费。多项研究表明，采用一定工艺处理后的建筑垃圾可以实现再生利用。但是目前建筑垃圾再生骨料品质较差，难以用于高等级道路结构层次中，且建筑垃圾处理企业尚未形成规模化体系，再生骨料成本较高。本课题依托省级高速公路西咸北环线，对西安市周边建筑垃圾进行回收和预分类，以高效和经济为原则，确定合适的设备类型和加工工艺，形成规模化加工建筑垃圾再生材料综合利用技术，，以期对我国建筑垃圾资源化利用提供一些有价值的参考。首先，通过对生活垃圾、建筑装修垃圾、建筑拆除垃圾、道路桥梁翻修垃圾等不同料源特性的建筑垃圾进行试验，提出各类垃圾的适用场合。基于目前建筑垃圾的现状，对建筑垃圾预处理技术进行研究，并结合国内外加工设备调研情况，完成建筑垃圾处理设备的选型工作。鉴于再生骨料中砖块、混凝土块性能差异较大，建议采用砖砼分离器实现砖块与混凝土块的分离。其次，结合道路用骨料的技术要求，提出分别应用于道路路基、基层乃至较高结构层次的经济型加工工艺和综合利用加工工艺，并对两套工艺的生产线进行三维动画模拟。基于成套生产工艺的研究，对兴平市建筑垃圾加工厂提出了设备改造及工艺优化方案。结果表明改造后再生骨料品质稳定，技术指标满足设计要求。最后，围绕建筑垃圾加工的要求，对依托工程建筑垃圾规模化生产场地区域和功能区的布局进行了规划。结合对国内外建筑垃圾加工场区的调查，设计了年处理建筑垃圾200万吨的洁净无尘化的规模化加工厂。并对经济型、综合利用两套生产工艺的再生骨料进行效益分析，证明建筑垃圾处理项目具有良好的经济和社会环境效益。
[Abstract]:In recent years, city to accelerate the process of the construction waste production showed a steep trend. A large number of construction waste not only destroy the ecological environment, land occupation, and caused the stone waste of resources. A number of studies have shown that the process of the construction waste can be recycled. But the recycled aggregate can be used in poor quality. The level of high grade road structure, and construction waste treatment enterprises has not yet formed a large scale system, recycled aggregate high cost. This research is supported by the Provincial Highway West Ham Nol, recovery and pre classification of surrounding buildings in Xi'an city garbage, in an efficient and economic principle, determine the type of equipment and proper processing technology, formed by technology comprehensive scale processing of construction waste recycled materials, in order to provide some valuable reference for China's construction waste resource utilization.
First of all, through the garbage, building renovation waste, building demolition waste, garbage road and bridge renovation of different material sources characteristics of construction waste test application put forward all kinds of waste. Based on the present situation of construction waste, to study the construction waste pretreatment technology, combined with the domestic research situation of processing equipment, complete construction waste treatment equipment selection work. In view of the bricks in recycled aggregate concrete blocks, differences in performance greatly, recommend the use of brick concrete brick and concrete block separator separation.
Secondly, in combination with the requirements for aggregate technology, put forward respectively applied in road subgrade, economical process and higher levels of grass-roots structure and comprehensive utilization of processing technology, and the two set of process production line for 3D animation simulation. The research based on the complete production process, equipment modification and optimization scheme of Xingping City construction waste processing plant is put forward. The results show that the aggregate quality stable regeneration after transformation, technical indicators meet the design requirements.
Finally, around the construction waste processing requirements, based on the engineering construction waste scale production area and function area layout of the planning. Combined with a survey of domestic and foreign construction waste processing field, the design of large-scale processing plant with annual processing 2 million tons of construction waste clean dust-free. And the economic type. The comprehensive utilization of recycled aggregate two sets of production process for the benefit analysis, proof of construction waste treatment project has good economic and social and environmental benefits.
