The present invention relates to a drain preventing device for preventing leakage of landfills, thereby preventing leachate from being lost.

In general, there are many ways to dispose of waste, but waste that is difficult to incinerate depends mainly on landfilling. One of the most important considerations when constructing a landfill is to prevent the contamination of the surrounding soil with leachate from landfilled wastes. Waterproof sheet composed mainly of high-density polyethylene is installed, and the order wall is able to withstand the load of waste by installing more than 50cm of order materials such as clay, hardened soil, and mixed soil to have a predetermined compressive strength to withstand the load of waste. And it is constructed so that the leachate does not leak by the waterproof sheet.

As described above, to prevent environmental pollution by leachate, it is prescribed to construct at least double the order layer which blocks leachate from leaking out of the landfill facility, and passes through the trash layer from the surface as well as the leachate generated from the trash itself. Provide leachate collection and drainage to quickly drain incoming stormwater.

The waste landfill leachate drainage device has various forms, and as shown in FIG. 1, a bottom collecting pipe 1 for collecting and extracting leachate is disposed at the bottom of the landfill, and the branch house is installed along the bottom slope of the landfill.
