Research on application of detecting technology of urban underground drainage pipelinein engineering survey
工程测量中城市地下排水管线探测技术应用研究

摘要

地下排水管网是贯穿城市建设过程的市政基础设施，具有收集输送工业废水、生活污水和雨水的功能，其状态与城市乃至国家的社会经济发展密切相关。随着我国城市化进程快速推进，传统排水系统难以适应新的城市格局，导致城市内涝、地面塌陷、环境污染等城市问题频发，应做好城市地下排水管线相关设施方面勘测工作，通过确定地下排水管线设施勘测需求，完成地下排水管线设施实地勘测工作，充分了解城市地下排水管线布置现况，进而为城市水务工作提供数据支持。地下排水管网作为保障公共安全、排洪防涝和控制水污染的关键，为应对全球气候变化及日趋密集的城市建设，开展地下管网普查，详细了解城市地下排水管网分布情况，对地下管网开展科学的规划、设计和管理是一项基础保障工作。

Abstract

The underground drainage network is the municipal infrastructure that runs through the urban construction process, which has the function of collecting and transporting industrial wastewater, domestic sewage and rainwater, and its state is closely related to the social and economic development of the city and even the country. With the rapid advancement of China's urbanization process, traditional drainage systems are difficult to adapt to the new urban pattern, resulting in frequent urban problems such as urban waterlogging, ground collapse and environmental pollution. It is necessary to do a good job in the investigation of urban underground drainage pipeline related facilities, and complete the field investigation of underground drainage pipeline facilities by determining the investigation requirements of underground drainage pipeline facilities. Fully understand the current situation of urban underground drainage pipeline layout, and then provide data support for urban water works. Underground drainage pipe network is the key to ensure public safety, flood drainage and waterlogging prevention and water pollution control. In order to cope with global climate change and increasingly dense urban construction, it is a basic guarantee job to carry out a general survey of the underground drainage pipe network, understand the distribution of the urban underground drainage pipe network in detail, and carry out scientific planning, design and management of underground pipe network.
