【摘要】 建筑垃圾又称为建筑废弃物，是指在对建筑物建设、维护和拆除活动中产生的对建筑物本身无用或是不需要的排出物料。据统计目前我国建筑垃圾总量已占到城市垃圾总量的30%～40%。在国家一直强调节能减排的大前提下，如何能合理地利用城市建筑垃圾资源，是关注的焦点。本研究以西咸北环线高速公路工程为依托，对如何加工建筑垃圾原料以满足公路路基填料需求，建筑垃圾填料如何碾压以及碾压过程中的含水率的控制和最大干密度能否满足路基填料的要求等问题进行了分析，通过对依托工程周边垃圾组成的分析，在对国内外建筑垃圾破碎设备了解的基础上，结合公路路基填料对粒径尺寸的要求，选出了合适的建筑垃圾破碎设备，提出了对建筑垃圾从初步筛分到剔除杂质然后再进行破碎成料的破碎工艺。本文还按照建筑垃圾主要组成成分配比建筑垃圾混合料，结合道路工程材料的特点，分析了不同配比混合料的最佳含水率、最大干密度、承载比和化学组成成分。最后，采用经过筛分和加工破碎后的建筑垃圾骨料填筑路基，通过测定不同碾压遍数下的路基沉降量和回弹弯沉等参数，从而得出建筑垃圾填筑路基合理的施工机械组合、碾压工艺、松铺厚度及压实质量控制方法。本研究成果对建筑垃圾再生利用和建筑垃圾填筑路基工程有借鉴作用。更多还原

【Abstract】 Building rubbishes, also known as building wastes, are the useless or theunnecessary materials that produced by the building construction, maintenance anddemolition activities. According to statistics, the total amount of building wastes inChina has accounted for30%to40%in total amount of urban wastes. Under thebackground of energy conservation and emission reduction, how to make full use ofthe urban building wastes has become the focus.This research is based on the Xixian North Link Line Project and makes analysis onseveral problems such as how to process building wastes in order to make them besatisfied with the requirement of the roadbed stuffing for expressway, how tolaminate the building wastes and how to control the moisture content during thelaminating process, whether the maximum dry density can be satisfied with therequirement of the roadbed stuffing and so on. By analyzing the component of thewastes around the support construction, the author picks out a suitable laminatingequipment for the building wastes as well as puts forward a laminating processwhich will laminate the wastes as the following steps: sieving-rejecting-laminating.This paper also prepares the building wastes mixture according to the mainconstituents of the building wastes. According to the features of the road engineering,this paper analyzes the best water content, the maximum dry density, the bearingradio and the chemical composition of the different mixture. Finally, fill theroadbed with building waste aggregates after screening and processed crushing,based on that, a reasonable construction machinery combination, grinding processand control method on the thickness of the layer, compaction degree in connectionwith roadbed filling with building wastes can be obtained by measuring roadbedsettlement amount and rebound deflection under different grinding frequencies.The results is useful for the recycling of the building wastes and the roadbedengineering filled by building wastes.更多还原
