[0002] Garbage refers to useless items or waste generated in daily life or production processes. These items no longer have economic value and cannot be used or consumed. Landfills are areas specifically used to treat and dispose of garbage. By burying garbage underground, it is managed and isolated. The main function of landfills is to safely and efficiently treat waste generated by cities and industries to avoid pollution to the environment and human health.

[0003] Liquid and methane are produced during the decomposition of garbage. To prevent them from polluting the environment and human health, drainage structures are required to treat and discharge them.

[0019] Working principle: First, place the garbage inside the landfill pit. After burying it, the garbage can decompose into liquid and methane through fermentation. The liquid can flow into the collection pool through the filter layer, and the liquid inside the collection pool can be discharged through the drainage well 1. The methane can flow into the storage pipe through the gas collection pipe, and then flow into the gas tank through the connecting gas pipe for temporary storage. When the methane in the gas tank needs to be treated, the air pump can be started and the methane inside the gas tank can be pumped into the decomposition pool through the pipeline. There are microorganisms inside the decomposition pool, which can treat the methane inside the decomposition pool through microorganisms and convert it into carbon dioxide and water. The volume diameter of carbon dioxide is about 0.33nm, and the volume diameter of methane is about 0.38nm, so that carbon dioxide can be discharged through the filter plate 1 inside the exhaust pipe, but methane cannot be discharged. The decomposition pool is connected to the connecting barrel through connecting pipe 1 and connecting pipe 2, thus forming a U-shaped tube structure, so that the internal liquid is highly consistent. The optimal moisture environment for microbial metabolism is 50% to 70%. When the liquid inside the decomposition pool is less, the float can be caused to drop, thereby driving the lifting rod to drop, and the lifting rod will rise. The lowering rod can drive the pressing block 1 to descend and press the connecting plate 1, thereby driving the rack plate 1 to descend, and then driving the gear 1 to rotate, so that the valve stem 1 rotates, thereby opening the valve 1, so that the liquid inside the water tank can flow into the decomposition tank through the connecting water pipe. When the water level inside the decomposition tank rises, the buoyancy of the float can drive the pressing block 1 to rise, and then the elastic force of the damper 1 drives the rack plate 1 to reset, thereby closing the valve 1. When the water level inside the decomposition tank is too high, the float can drive the lifting block 1 to rise, and then drive the pressing block 1 to press the connecting plate 1. Block 2 rises, and then the rack plate 2 is pushed up by pressing block 2, and the valve stem 2 is driven to rotate by gear 2, thereby opening the drain pipe 1 and discharging the liquid inside the decomposition tank. As the water level gradually drops, the lifting block drops accordingly, releasing the pressure on the pressing block 2, and then the valve stem 2 is reset by the elastic force of the damper 2, closing the drain pipe 1. By controlling the humidity range inside the decomposition tank, sufficient water can be provided for the metabolism of microorganisms without causing an anaerobic environment caused by excessive water, thereby promoting the proliferation of microorganisms and increasing the degradation rate.

[0020] The present invention provides a highly efficient drainage structure for landfills, which has the following beneficial effects:

[0021] 1. The present invention can form a U-shaped tube structure by connecting pipe 1, connecting pipe 2, connecting barrel and decomposition tank, so that the liquid height is the same. At the same time, installing filter plate 2 inside connecting pipe 2 can also prevent methane diffusion. Then, the humidity range inside the decomposition tank is controlled by the float inside the connecting barrel. When the humidity is low, the float drops and drives valve stem 1 to rotate, thereby opening the connecting water pipe to discharge the liquid inside the water tank into the decomposition tank. When the humidity inside the decomposition tank is high, the float rises and drives valve stem 2 to rotate, thereby opening drain pipe 1 to discharge the liquid. Controlling the humidity range inside the decomposition tank can promote the proliferation of microorganisms, thereby increasing the degradation rate.

[0022] 2. The present invention can discharge the liquid generated by the fermentation of landfill garbage into the collection pool through the filter layer, and then discharge the liquid through the drainage well 1. By arranging rainwater collection ports and drainage wells 3 around the landfill pit, rainwater can be prevented from eroding the landfill and the generation of leachate can be reduced.
