Description

Technical Field

[0001] The utility model relates to the technical field of HDPE films, in particular to a signal receiving and transmitting device on an anti-seepage layer HDPE film. Background Art

[0002] Landfill technology is the final disposal method for domestic waste. Before landfilling, HDPE membrane is usually installed on the bottom layer to prevent infiltration. It is currently the main method for most cities in China to solve the problem of domestic waste disposal. In order to prevent groundwater pollution, the landfill anti-seepage layer system is an indispensable facility for landfill construction. In recent years, HDPE membrane has been widely used as the anti-seepage layer of landfills in my country. However, during the construction and later use of landfills, HDPE membranes are prone to leakage due to various factors. If these loopholes are not discovered and repaired in time, they will inevitably affect the anti-seepage effect of the project. The leachate will enter the groundwater and soil through the damaged loopholes, causing pollution to the surrounding water and soil environment. Therefore, the leakage problem of landfills has received more and more attention.

[0003] The invention patent with the authorization announcement number CN110779659A discloses a device and method for detecting damage and leakage of the impermeable layer of a landfill that can be automatically marked. The invention includes a remote control and a detection vehicle. A control box, an alarm, a driver and a signal receiving and transmitting device are arranged above the detection vehicle; the signal receiving and transmitting device is connected to the driver; the alarm is connected to the controller; a brush-type detection probe is arranged below the detection vehicle, and the controller is connected to the brush-type detection probe through a lifting shaft; a marking device is arranged on the lifting shaft. The present invention can be used to perform more detailed detection of the fine and wrinkled parts of the high-density polyethylene film, and automatic marking can be achieved after the leak is detected, avoiding the operator's constant following and greatly reducing the workload of the staff.

[0004] Although the above invention can detect whether there is a leak under the inspection vehicle, when the inspection mechanism detects a leak, the leak may have existed for a certain period of time, and the leachate may have caused a certain degree of pollution to the surrounding water and soil environment. In view of this, we propose a signal receiving and transmitting device on the HDPE membrane of the anti-seepage layer. Utility Model Content
