摘要
排水管网是城市重要的基础设施,随着使用时间的延长,部分管网开始出现不同类型的问题,急需修复。老旧管网修复是污水提质增效、黑臭水体治理的重要一环,缺陷管网修复工艺的选择至关重要。现结合深圳市某片区202.77 km现状排水管道的检测成果,主要对结构性缺陷管网的两种修复方式开挖换管和非开挖修复进行了对比,分析了各修复技术的适用条件及优缺点,详细介绍了修复工艺选择中应考虑的各项因素,最后针对非开挖修复的应用进行了论述。
Drainage pipe network is an important urban infrastructure.With the extension of service time,some pipe networks begin to have some different problems and need to be repaired urgently.The repair of old pipe network is an important part of sewage quality and efficiency improvement,and black and odorous water treatment.The selection of repair process of defective pipe network is very important.Combined with the investigation results of the 202.22-km present drainage pipeline in a district in Shenzhen,two repair methods of excavation and pipe replacement,and trenchless repairof structural defective pipe network are compared.The applicable conditions,advantages and disadvantages of each repair technology are analyzed.The factors that should be considered in the selection of repair process are introduced in detail.The application of trenchless repair is discussed.
