非正规地上垃圾堆放点精准勘测技术应用研究

近年来,国内出现了越来越多在地表直接堆填形成的非正规地上垃圾堆放点,因其堆填高、形状不规则,往往不具备或仅部分区域具备钻探实施条件,因此在应用现有《污染场地勘察规范》时存在较大的局限性。为准确查明满足治理方案设计所需参数,迫切需要开展针对地上垃圾堆放点的精准勘测技术研究。本文结合近年来勘测工程实践经验,系统总结了非正规地上垃圾堆放点勘测的工作内容、工作程序和技术要求。尤其是,本文提出了采用测绘手段精准测算垃圾方量,采用大方量垃圾样品开展筛分中试试验、密度试验,以便精准测算筛分产物分类及比例以及垃圾重量,极大提高了地上垃圾堆放点勘测的精度。工程实践结果表明,本文提出的勘测技术方法科学合理、可操作性强,在类似非正规地上垃圾堆放点勘测中具有重要的参考价值。

Study on the accurate survey technique for informal ground landfill sites

Recently,there have been more and more informal landfill sites formed by direct land filling on the ground in China. Due to the irregularity of their height and shape,there is no or only part of the area to have the conditions to implement the drilling survey. Therefore,there are significant limitations when"Code to for Investigation of Contaminated Sites"is applied. In order to accurately identify the parameters to meet the requirements of the treatment plan designing,there is an urgent need to carry out precise survey technique study on the ground landfill sites. This article combines the practical experience of survey engineering in recent years, and systematically summarizes the work content, work procedures and technical requirements of the survey of informal landfill sites on the ground. In particular,the use of surveying and mapping methods to accurately measure the amount of waste is proposed,and the large amounts of waste samples to conduct screening pilot tests and density tests to accurately measure the classification and proportion of screening products and the weight of wastes are used,which greatly improve the accuracy of the landfill site survey on the ground. The engineering practice results show that the survey technique method proposed in this paper is scientific and reasonable and has strong operability,and it has important reference value in the survey for the similar informal ground landfill sites.
