Embodiment Construction

[0018] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0019] figure 1 It is a structural schematic diagram of an embodiment of the present invention.

[0020] Such as figure 1 Shown: a landfill surface sealing system, which is provided with a surface layer 1, a protective layer 2, a drainage layer 3, an anti-seepage layer 4 and an exhaust layer 5 in sequence from top to bottom. Wherein, a surface water control layer is also provided in the surface layer 1, and the material of the surface layer 1 is humus, and its thickness is greater than 60 cm. In this embodiment, its thickness is 75 cm. The material of the protective layer 2 is natural soil, of course, it can also be gravel. In addition, the water permeability of the drainage layer 3 is greater than 10 -2 cm / s, the slope is greater than 4%. The thickness of the anti-seepage layer is greater than 60 cm. In this embodiment, its thicknes...

Abstract

The invention discloses a landfill surface filling system. The landfill surface filling system is sequentially provided with a surface layer, a protection layer, a drainage layer, an anti-seepage layer and an exhaust layer from top to bottom. The surface layer has the land restoration function, the protection layer is used for protecting the lower layer against damage caused by plants or animals or the like on the upper layer, the drainage layer can effectively reduce pressure on the lower anti-seepage layer, the anti-seepage layer can effectively prevent seeping water from entering buried waste, and the exhaust layer is mainly used for controlling gas of a landfill and avoiding damage to the anti-seepage layer caused by high pressure gas. In short, the landfill surface sealing system is good in sealing effect and has the exhaust function, and service life is prolonged.

Description

technical field [0001] The invention relates to a sealing system, in particular to a landfill surface sealing system, which belongs to the technical field of solid waste treatment systems. Background technique [0002] There are many ways to treat solid waste. Among them, landfill disposal has the advantages of simple process, low cost, and is suitable for various types of solid waste. However, the main problem of this treatment method is the collection and control of leachate. In the actual application process, its sealing system is not ideal, once it is damaged, it is difficult to order, and due to the improvement of environmental control standards, its disposal costs are also increasing, which undoubtedly brings this kind of solid waste disposal. There are great difficulties in application. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the object of the present invention is to provide a landfill surface sealing system with good...
