Characteristics of urban underground pipe network 1, the working environment special, underground pipelines in general, in the city along streets into urban population density, flow, traffic is heavy, heavy traffic, construction interference factors, adverse effects to the construction, at the same time safety equipment for the body and cause a great threat. 2, work objects and special content. Pipeline measuring not only the location and elevation plane mapping pipeline points, but also on the ground related to mapping feature landscape. Situation urban underground pipe network measurements of a zero-crossing method. Commonly known as the mute point method, called triangulation abroad 2, the horizontal component of the feature point method, called offset foreign law 3, the horizontal component of the vertical difference between the law and foreign law known as dual antenna detection scheme that can In the pipeline while positioning directly read its depth, so-called direct reading depth method.
