摘要
污水管网人工清淤检测是一种重要且常规的手段,污水中有机物被分解、氧化或还原产生的气体带有较大毒性。为确保项目中井下作业人员的安全,依照相关行业规范与现有研究成果,通过现场实施与研究,总结出了下井作业安全规范工序流程,确定了合理施工人员和机具布置,并制定了针对性保障措施,以期对城市污水管网有限空间作业提供技术参考。
The artificial silting detection of sewage network is an important and conventional means,the gas produced by the decomposition,oxidation or reduction of organic matter in sewage is more toxic.In order to ensure the safety of underground workers in the project,according to the relevant industry norms and existing research results,through on-site implementation and research,the paper summarizes the safety standard process of downhole operations,determines reasonable construction personnel and implement arrangements,and formulates targeted safeguards,to provide a technical reference for the limited space operation of urban sewage pipe network.
