Description

Technical Field

[0001] The utility model relates to the technical field of geomembrane damage detection, in particular to a geomembrane damage detection device. Background Art

[0002] Geomembrane is a synthetic material with good anti-seepage performance. It is widely used in water conservancy projects, landfills, tunnels and underground projects to prevent water leakage and protect soil and the environment. However, geomembranes may be damaged by mechanical damage, environmental impact or improper construction during long-term use, resulting in the failure of their anti-seepage function. Therefore, it is very important to use a geomembrane damage detection device, which can monitor the status of the membrane in real time, detect damage in time, evaluate its integrity, ensure the safety and long-term stability of the project, and avoid environmental pollution and economic losses caused by geomembrane damage. Through effective detection and maintenance, the service life of the geomembrane can be extended and the overall reliability of the project can be improved.

[0003] Traditional geomembrane damage detection devices usually include technologies such as resistance method, ultrasonic method and visual inspection. When in use, the resistance sensor is first installed in key areas of the geomembrane, such as seams and edges, to ensure good contact and connect to the data acquisition system. During the monitoring process, the sensor records the resistance value of the membrane in real time to determine whether there is any damage. In addition, ultrasonic detection technology evaluates the integrity of the membrane by emitting ultrasonic signals and receiving reflected waves, which is suitable for identifying tiny cracks. Visual inspection is used to regularly inspect the surface of the membrane and identify obvious damage. Through the combination of these methods, the status of the geomembrane can be fully monitored, potential problems can be discovered and dealt with in a timely manner, thereby ensuring the safety and effectiveness of the project.
