Description
技术领域technical field
本实用新型涉及一种探测地下污水管网位置的系统，属于地下管网探测领域。The utility model relates to a system for detecting the position of an underground sewage pipe network, which belongs to the field of underground pipe network detection.
背景技术Background technique
随着城镇规模的扩大，与人民生活息息相关的污水管网通常沿用以前修建的污水管道，很多检修井被施工覆盖，加之资料的缺失，很多污水管道的位置已经无法确认。位置不明的污水管道对因管网老化导致的排水安全及地下新建工程的施工安全构成了威胁，同时也不利于城市排水的综合管理，因此查明这些管道的位置尤为重要。目前针对地下管网通常采用地质雷达、浅层地震、高密度电法及管线探测仪进行探测，但由于污水管道埋深大且导电性差，以上方法对污水管道的探测效果往往不佳。本实用新型就是为了解决污水管网的探测问题。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 burial of sewage pipes and poor conductivity, the detection effect of the above methods is often not good for sewage pipes. The utility model aims to solve the detection problem of the sewage pipe network.
