Abstract

The invention relates to a system for detecting the position of an underground sewage pipe network, belonging to the field of underground pipeline network detection. The system is composed of two parts, namely an emitting device and a receiving device, wherein the emitting device consists of a frequency emitter (1), a power controller (2) and a floating raft (4) which are separately arranged on a power supply cable (3) and an emitting coil (5) arranged on the floating raft (4); the receiving device consists of a tablet personal computer (6), and a low frequency receiving coil (7), a low frequency signal amplifier (8), a high frequency receiving coil (9), a high frequency signal amplifier (10) and a data acquisition card (11) connected to one another through connecting lines. The system provided by the invention has the beneficial effects of simple structure, low cost, convenience in operation, wide application range, capability of detecting positions of underground sewage pipeline networks of various materials, and precise detection result.

Description

technical field [0001] The invention relates to a system for detecting the position of an underground sewage pipe network, which belongs to the field of underground pipe network detection. Background technique [0002] With the expansion of urban scale, the sewage pipe network closely related to people's life usually uses the sewage pipes built before, and many maintenance wells are covered by construction. In addition to the lack of data, the location of many sewage pipes can no longer be confirmed. Unknown sewage pipes pose a threat to the drainage safety caused by the aging pipe network and the construction safety of new underground projects, and are not conducive to the comprehensive management of urban drainage, so it is particularly important to find out the location of these pipes. At present, geological radar, shallow seismic, high-density electrical method and pipeline detector are usually used for detection of underground pipe network. However, due to the deep buri...
