城镇排水管渠检测、清淤与非开挖修复标准体系思考

Consideration of standard system for inspection,dredging and trenchless rehabilitation of municipal sewer

针对现有排水管渠检测、清淤和非开挖修复标准进行归纳和讨论,综述了欧美发达国家相关标准情况,并统计和研究了我国这一领域的标准体系结构。结果表明:城镇排水管渠检测、清淤和非开挖修复领域现有标准数量共30项,其中国家标准4项,行业标准10项,地方标准11项,团体标准3项,企业标准2项;标准体系可按基础、通用和专用层次划分,初步形成了多级别和多层次的互补性结构。但是,标准数量欠缺明显,尚缺乏检测设备产品标准、通沟污泥的处理与处置标准和管道非开挖修复材料的产品标准,在一定程度上限制了该行业的发展,急需制定相关标准进行补充,以满足行业快速发展的需求。

The existing sewer inspection,dredging and trenchless rehabilitation standards were collected and discussed.The relevant standards in developed countries in Europe and America were summarized.And the standard system structure of this field in China was statistically studied.The results show that there are a total of 30 existing standards in the field of urban sewer inspection,dredging and trenchless rehabilitation,including 4 national standards,10 industry standards,11 local standards,3 group standards,and 2 enterprise standards.The standard system can be divided into basic,general and special levels.A multi-grade and multi-class complementary structure has been initially formed.However,the number of standards is obviously insufficient,and there is still a lack of product standards for testing equipment,standards for the treatment and disposal of dredging sludge,and product standards for trenchless rehabilitation materials,which limits the development of the industry to certain extent.It is urgent to establish relevant standards to supplement in order to meet the needs of the industry.
