With the rapid development of the urban economy,in order to meet the needs of urban production and residence,more and more underground pipe network are laid under-ground.In order to understand the distribution and structure of urban underground pipe-lines,improve the efficiency of urban management,ensure urban safety,and support urban planning,construction,disaster prevention and relief,etc.,a proper urban underground pipeline detection technology is indispensable.This article introduces the principles of pipe-line detection methods and various applicable conditions in detail.Through the examples of underground pipeline detection projects in the Ganzhou region of Shenzhen-Jiangxi Port Pro-duction City Special Cooperation Zone Project,the comprehensive detection and applications of the electromagnetic induction method and the exploration radar method supplement and verify each other.The actual excavation verification plane error is less than 3 cm,and the depth error difference is less than 6 cm,which is less than the accuracy limit setting of the specification setting.It shows the effectiveness and accuracy of comprehensive detection technology on the underground pipe network,which can provide effective safety construction guarantees for urban road reconstruction projects.
