In the construction and operation of urban infrastructure, the safety and stability of underground pipelines are crucial. However, due to long-term use, material aging, natural disasters and other reasons, underground pipelines are prone to water leakage accidents. If leaks are not detected and solved in time, they can have a serious impact on the normal operation of cities and the lives of residents. Therefore, it is essential to use advanced detection instruments in the management of underground pipelines.

Currently, there are a variety of instruments on the market that are suitable for underground pipeline leakage detection. Among them, the most common and commonly used are acoustic wave detectors and thermal imagers.

A sonic detector is an instrument that detects water leaks inside a pipe through sound. The instrument collects sound signals from inside the pipe through sensors placed near the pipe and uses signal processing algorithms to determine if there is a leak in the pipe. This method is mainly applicable to pipes made of hard materials such as metal or plastic pipes. The advantages of the acoustic detector is simple and easy to operate, fast response time, high accuracy, while its price is also relatively affordable. However, the use of acoustic wave detector requires a certain degree of expertise and experience, otherwise there may be misjudgment or missed detection phenomenon.

Thermal imager is an instrument that detects pipe leaks through changes in heat. When a water leak occurs in a pipe, a local temperature change is produced because the temperature of the water flow and the temperature of the surrounding environment are different. By aiming the thermal imager at this local area, a high-resolution infrared thermal image can be obtained and an image processing algorithm can be used to determine whether there is a water leak in the pipe. This method is mainly applicable to subway tunnels, HVAC pipes and other pipes with soft materials and easy bending. The advantages of thermal imagers are simple operation, no need to touch the surface of the pipe, and the ability to quickly detect water leaks in the pipe. However, the price of the thermal imager is relatively high, and at the same time it is affected by factors such as temperature, wind speed and outdoor lighting, and needs to be used under specific environmental conditions.

In addition to the above two common instruments, there are other types of instruments, such as pressure probes, ultrasonic detectors, electromagnetic detectors, etc. Each type of testing instrument has its applicable pipe type and testing principle, and choosing the right instrument for testing according to the actual situation can more effectively find and solve the pipe leakage problem.

In short, the leakage problem of underground pipelines needs to be paid attention to and solved by adopting scientific and advanced detection instruments. In the selection of pipeline leakage detection instruments, should be based on the type of pipeline, environmental conditions, technical requirements and other aspects of comprehensive consideration, and equipped with professional personnel to operate, in order to ensure the accuracy and reliability of the test results.
