The present invention discloses a detection method and a device of an underground non-metallic pipe diameter. The method comprises the following steps: (1) determining the general direction of a target pipe according to field investigation and data surveying and mapping, or putting a transmitting probe into the pipe; the transmitting probe transmitting an electromagnetic signal; a receiver tracking the electromagnetic signal transmitted by the probe; determining the pipe direction by detecting the position of the probe; and selecting a smooth ground and laying a measuring line along the perpendicular direction of the pipe direction. The device has the advantages of scientific and reasonable structure and safety and convenience in use, a ground penetrating radar is clamped between clampingplates, each clamping plate compresses a corresponding compression spring, the elastic force produced by each compression spring acts on the corresponding clamping plate after the compression spring is compressed, so that the clamping plates can fix the ground penetrating radar, and thus the device is convenient for the disassembly and the installation of the ground penetrating radar. A rotating bracket can adjust the angle of a monitor of the ground penetrating radar, a fastening bolt and a fixing nut are matchedly connected, so that the angle of the monitor of the ground penetrating radar isfixed, and thus the device is convenient for a working staff to observe the monitor of the ground penetrating radar.
Description
technical field [0001] The invention relates to the field of detection equipment for underground non-metallic pipe diameters, in particular to a detection method and device for underground non-metallic pipe diameters. Background technique [0002] The urban underground pipeline is the blood and nerve of the city, and it is the guarantee for the normal operation of the city. With the continuous acceleration of urbanization, the materials of urban underground pipelines are becoming more and more abundant, and non-metallic pipelines have replaced metal pipelines in large quantities. The metal pipeline itself is electrically conductive and magnetically conductive, and generally has obvious physical property differences with the surrounding medium. Fast and effective methods such as electromagnetic induction can be used. Non-metallic pipelines are non-conductive and magnetically conductive, and the physical properties of the surrounding medium are small. The tracer electromagnet...
