The urban underground pipe network plays a vital role in the city development, the construction of unreasonable urban pipe networks restricts the city development, even has a disastrous effect on the city. However, it is not desirable to overstate the investment of the urban underground pipe network excessively. It is an important subject of the city construction that how to establish reasonable urban pipe networks to meet service conditions of underground pipe networks. Because the construction of underground drainage pipe networks of most of the major cities in our country mainly comes from the 50s of last century and there are more pipe network system with the development of the city, it is the main content of our research that how to reform and construct them under the condition of existing underground pipe networks.

This paper mainly introduces a device that can be used for underground pipeline survey task. Through the cameras installed on the device, we can obtain stereo synchronous shooting images, and then use the method of close range photogrammetry to investigate and measure underground objects. During working process, the staff put the camera into the well and to control camera shooting from the ground. Greatly improve work efficiency, at the same time to avoid the underground toxis gas damage to people. The main content of this paper includes three parts: hardware design, software development and test production.

By collecting the data of the ground scene and non-destructive detecting of the underground pipe network, using freeform software design of the data collected by the three-dimensional color modeling and rapid prototyping systems will underground complex pipeline modeling, using ground-dimensional graphics and three-dimensional model of underground pipe network combined method, This paper is trying to find out an effective presentation method for the distribution of underground pipe network. Thus, an efficient, realistic, intuitive three-dimensional rapid mapping prototyping service technology corresponds to the ground and underground pipe network scenario is applied to urban planning, municipal infrastructure, scientific management, maintenance and reconstruction.

To resolve the problem that underground pipe network is large, complex, and difficult to manage, the management model based on ArcGIS was used. This paper aimed to transform the traditional data types of underground pipe network to a new type based on ArcGIS and to make statistical analysis and thematic maps output to the attribute datas for all underground pipes mainly including water supply network and drainage network. Through the analysis of pipe network visualization model implementation to build the spatial data model of three-dimensional pipe network, the automatic model from 2D to 3D would be achieved, then the new ways to realize the 3D visualization of urban underground pipe network would be provided. Taking the underground pipe network of a city as an example, the management system based on ArcGIS was built. The system running results show that the system could achieve the digital management of underground pipe network for the city and improve the management efficiency of the entire system.
