Problems solved by technology

This method occupies a certain amount of landfill capacity, and the covering soil must be clay with a small permeability coefficient, otherwise it will not be able to prevent the vertical infiltration of rainwater and increase the amount of seepage water, and this covering method is limited by weather and equipment conditions. unable to proceed in time
However, in plain landfills where soil resources are in short supply, the daily coverage is basically not achieved at present.
For areas that have reached the height of landfill, there are also problems that cannot be covered in time due to the shortage of soil sources and weather reasons, resulting in the exposure of garbage for a period of time, causing mosquitoes and flies to breed, emitting odors, and affecting the environment.
At present, the fly killing in the landfill is basically the killing of flies by medicine, which easily causes secondary pollution, has a certain impact on the health of pharmaceutical workers, and is expensive

Embodiment Construction

[0006] In the figure, the edges of the two covering films 1 and 2 are overlapped and then placed between the two fixing strips 3 and 4 and fixed by iron nails 5 . Among them, the cover film adopts high-density polyethylene film. The specific covering process is as follows: a. Divide the covering film according to the length; b. The first piece of film should be laid from the side of the embankment in the unit landfill area to the center of the pile, and then put the film from the other side to the center of the pile. There should be an overlap of 5-10 cm at the point, and two pieces of wooden strips should be clamped up and down, and then fixed with iron nails, which can be laid continuously in sequence; c. Lay down to the embankment; e. The junction and edge of the membrane should be pressed firmly with a woven bag filled with soil. Among them, the wooden strips should be treated with anti-corrosion.

Abstract

The covering process for domestic garbage landfill features cutting the covering film into certain length; spreading covering film from the separation ridge towards the center of garbage pile with the superposing part of 8 cm width in the seam being clamped with the upper and lower wood strips and fixed with iron nails; the film in the exposed bevel area are combined with the first film and spread in T-shape to the separating ridge; pressing the film seams and edges with woven bags with soil. The present invention has smart design, consumes no filling capacity, can kill fly egg to avoid fly propagation, exhaust rain water to avoid vertical permeation, control bad smell and use the material circularly.

Description

Technical field: [0001] The invention relates to a covering technology, in particular to a technology for covering domestic waste landfill waste. Background technique: [0002] In valley landfills with relatively rich soil sources, cover 20 to 30 cm with soil daily. This method occupies a certain amount of landfill capacity, and the covering soil must be clay with a small permeability coefficient, otherwise it will not be able to prevent the vertical infiltration of rainwater and increase the amount of seepage water, and this covering method is limited by weather and equipment conditions. Unable to proceed in time. However, in plain landfills where soil resources are scarce, the daily coverage is basically not achieved at present. For the areas that have reached the landfill height, due to the shortage of soil sources and weather reasons, they cannot be covered in time, resulting in the exposure of the garbage for a period of time, causing the breeding of mosquitoes and fl...
