Abstract:
The general survey of urban underground pipeline is a systemic engineering, which is involved with many institutions, departments, specialties and processes. Based on the sequence of engineering construction, this paper elaborates the main work contents of the related units in the preliminary preparation stage, field construction stage, office data processing and data sorting stage. The geophysical exploration technology and methods used in the construction stage of the project is discussed. The solutions to the difficult problems encountered are put forward in the construction process of the project by adopting the comprehensive geophysical exploration method. The importance of quality control and the necessity of implementing engineering supervision mechanism are emphasized. Finally, some suggestions are put forward for the dynamic management mode in the later stage of the general survey. The conclusions and suggestions can be used for reference in the general survey of urban underground pipelines.
