Tap water carried by underground pipes in small communities may leak over a long period of time, and when a leak occurs, no signs may be found on the surface. Even if water is seeping from the surface, the seepage point is not necessarily the leak point, especially if the ground is covered with a

　　Geothermal wells are drilled wells for geothermal steam and geothermal water. It is an important and special technology, which is necessary for exploration and exploitation of geothermal fluids. For high-temperature geothermal fields, the depth of drilling is generally between 500 meters and 2,000

　　Even if the pipes are of good quality, they will gradually deteriorate during use and inevitably leak. However, many pipes are buried or hidden underground and therefore invisible, which makes maintenance more difficult. In the past, a small pipe leak might have made a mess of the ground, but now

　　When geothermal wells are drilled, thermal response experiments are usually conducted through test wells, and then more accurate data are obtained through special software calculations before drilling.　　1、According to the hydrogeological investigation report and water resources demonstration repor

One of the most important aspects of spa project development is spa drilling, so in the early stages of spa construction it is necessary to find a spa drilling company with good quality, good service and good after-sales service to drill the well. In order to ensure the successful completion of the

　　Underground pipeline engineering facilities, throughout the construction process, is an important infrastructure of the city. Its water supply, drainage, gas supply, communication cables, electricity, etc., constitute the "lifeline" of the city, and are responsible for the city's energy supply, in

Urban underground pipelines are increasingly interlaced and dense, and the categories of pipelines, materials, construction methods, etc. are constantly changing, which increases the difficulty of pipeline detection. The detection of urban underground pipelines is mainly based on the material of pip

　　Underground pipeline is an important infrastructure of the city. In recent years, with the development of urban construction, vigorous development of transportation systems, energy systems, communications, information networks, such as railroads, subways, light rail, power supply, heating, gas sup

　　Where there are people, there are pipeline leaks, and the dense underground pipelines are like the vascular network of the human body, such as household water pipelines, household floor heating pipelines, urban fire pipelines, urban water supply pipelines, urban heating pipelines, these pipelines

Underground water pipe leak detection is a comprehensive and complex work, need to use a combination of ground sound intensity and audio with detection, pipeline sound intensity and pipeline distance sound intensity audio detection and other methods, comprehensive analysis of valve bolt detection, r
