Description

Technical Field

[0001] The invention relates to the technical field of garbage landfills, in particular to a garbage landfill covering system. Background Art

[0002] Landfill cover soil serves a variety of purposes, including sanitation, fire prevention, reduction of leachate volume, odor management, and pest control. Waste dumped on the ground should be buried whenever possible. It should be sealed with cover soil as soon as possible. To prevent the spread of gases, fire, and, when necessary, the movement of collection vehicles, soil must be covered in designated areas. The final layer of soil will be applied to the top layer of the landfill. In this case, the intended use of the landfill facility determines the final thickness of the soil cover. The cover soil must adequately cover the landfill waste, be evenly distributed and compacted, and have an appropriate thickness and slope.

[0003] After the landfill is covered, the landfill cover system only strengthens the anti-seepage and combustible gas. There are still a large number of pests in the garbage. These pests will reproduce under the soil and dig the soil and anti-seepage layer (1), which will cause damage to the landfill system of the landfill. Summary of the invention

[0004] In order to solve the problems raised in the above background technology, the purpose of the present invention is to provide a landfill covering system, which has the advantage of being able to continuously kill pests.

[0005] To achieve the above object, the present invention provides the following technical solution: a landfill covering system, comprising an anti-seepage layer, a pest trapping layer, a garbage layer, a clay layer and a nutrient soil arranged in sequence from bottom to top, the pest trapping layer comprising an insect trapping pipe and an insect killing pipe, and the insect killing pipe is provided with an insect trapping mechanism and an insect killing mechanism inside;

[0006] The insect attracting mechanism comprises an insect attracting gas storage box fixedly connected to the top of the insecticidal pipe, a hair dryer is fixedly connected to the inside of the insecticidal pipe, the air inlet of the hair dryer is connected to the insect attracting gas storage box through a pipe, and the air outlet of the hair dryer is connected to the insect attracting pipe through a pipe;

[0007] The insecticidal mechanism includes an insecticidal liquid storage box fixedly connected to the top of the insecticidal pipe, a water pump and an atomizing nozzle are fixedly connected inside the insecticidal pipe, a water outlet of the water pump is connected to the atomizing nozzle through a pipe, a water inlet of the water pump is connected to the insecticidal liquid storage box through a pipe, the tops of the insect-attracting gas storage box and the insecticidal liquid storage box are both connected with a conveying pipe, the top of the conveying pipe passes through the pest trapping layer, the garbage layer, the clay layer and the nutrient soil in sequence and extends to the top of the nutrient soil.

[0008] As a preferred embodiment of the present invention, the insect-attracting pipe is arranged to penetrate the inside of the insect-killing pipe, both ends of the insect-attracting pipe extend to the outside of the insect-killing pipe, wormholes are arranged on the surface of the insect-attracting pipe, and pebbles are arranged on the outside of the insect-attracting pipe and the insect-killing pipe.

[0009] As a preferred embodiment of the present invention, the anti-seepage layer is a geomembrane made of high molecular polyethylene.

[0010] As a preferred embodiment of the present invention, a pressure detector is provided inside the insect attractant gas storage box, and a solenoid valve is provided inside the pipeline between the hair dryer and the insect attractant gas storage box.

[0011] As a preferred embodiment of the present invention, a liquid level meter is provided inside the insecticide liquid storage box.

[0012] As a preferred embodiment of the present invention, an insect-attracting lamp is fixedly connected to the interior of the insect-killing pipe.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The present invention sets a pest trapping layer. When trapping, the trapping gas is first discharged and then the insecticide is discharged to carry out the trapping and killing work. The pests in the garbage can be killed to a great extent, and the pests are prevented from damaging the landfill system, thereby achieving the purpose of continuously killing the pests after landfill.

[0015] 2. The present invention sets an insect-attracting pipe and an insect-killing pipe. The insect-attracting pipe is set to be smaller than the insect-killing pipe. When pests enter the insect-killing pipe from the wormhole, the internal space of the insect-killing pipe is larger, and they can be killed after large-scale storage, avoiding the waste of insecticide liquid. The setting of pebbles can leave crawling space for insects, thereby better luring and killing most pests, and can fix and protect the insect-attracting pipe and the insect-killing pipe.

[0016] 3. The present invention provides a geomembrane made of high molecular polyethylene, which is impact-resistant, wear-resistant, has good self-lubricating properties and excellent low-temperature properties, and can better prevent the seepage of leachate.

[0017] 4. The present invention can detect the air pressure inside the insect-attracting gas storage box by setting up an air pressure detector, thereby facilitating the staff to observe the gas inventory in the insect-attracting gas storage box in real time and replenish the insect-attracting gas in time. The setting of the solenoid valve can avoid the loss caused by the leakage of the insect-attracting gas and can facilitate the staff to remotely control the opening and closing of the valve.

[0018] 5. The present invention can detect the liquid level inside the insecticide storage box by providing a liquid level meter, thereby facilitating the staff to observe the liquid inventory in the insecticide storage box in real time and replenish the insecticide in time.

[0019] 6. The present invention provides an insect-attracting lamp, which enhances the ability to trap pests and allows the pests to be better concentrated in the pest-killing pipeline. BRIEF DESCRIPTION OF THE DRAWINGS
