民用建筑施工建筑垃圾产出量统计分析研究

Statistical Analysis on Construction Waste Amount in Civil Building

工程施工建筑垃圾的产出量,是预测工程全过程建筑垃圾数量,规划建筑垃圾循环利用的基础数据之一,也对制订建筑垃圾源头减量化措施和编制有关评价标准具有指导作用。本文采集了132个民用建筑工程施工建筑垃圾产出的有关数据,采用统计分析方法研究得到,民用建筑施工每万平方米建筑垃圾的产出量平均值约为250吨,与是否是居住建筑、办公建筑还是其他公共建筑的类型无显著差异,可以合并统计。建议编制相关评价标准中,作为一般要求,可采用每万平方米建筑垃圾的产出量为300吨,建筑垃圾现场回收利用率为35%;较高要求分别为200吨和65%。

The output of construction waste in engineering construction is one of the basic data for predicting the quantity of whole construction waste and planning the recycling of construction waste.It also plays a guiding role in formulating the measures of construction waste minimization from source and compiling the relevant evaluation standards.The statistical analysis of the collected construction waste amount of 132 civil building projects shows that average quantity of construction waste per 10,000 square meters is about250 tons,which is not significantly different from the type of residential building,office building or other public building.It is suggested that in the compilation of relevant evaluation standards,as a general item,the quantity of construction waste per 10,000 square meters can be 300 tons,and the on-site recycling and reuse rate of construction waste is 35%.The extra item can be 200 tons and 65%,respectively.
