The tensile strength of the heavy duty pond liner for sale in landfills is stronger than the usual impermeable geomembrane, and the application life will be longer. In order to prevent damage from rainwater, the acid resistance of this landfill impermeable geomembrane is much stronger and the application is not the same in different areas.
Heavy duty pond liner for sale is a combination of high-density and medium-density polyethylene, one side is smooth and the other side is rough, but also the landfill special geomembrane, landfill compared to ordinary geomembrane, acidic resistance, stretching ductility is stronger, so the state also has high requirements for the quality of geomembrane.
Case Study
- Location – the Philippines
- Product – Heavy Duty Pond Liner for sale
- Application – Landfill Project
Issue
A Philippine customer sent a landfill bidding project to purchase 1.5mm geomembrane. By comparing various indicators, BPM recommends customers to use the new geomembrane and makes the most competitive quotation. Then we sent BPM company qualifications, third-party inspection reports and some large-scale landfill cases previously constructed.
Solution
The closure of a landfill site is subject to the following points:
1. The structure of the closure covering system should be divided into: exhaust layer, anti-seepage layer, drainage layer and vegetation layer in order from the surface of the garbage dump body to the top surface.
The layers of the enclosure cover system shall be selected from the following types:
1) Exhaust layer: The landfill cover system should be equipped with an exhaust layer so that the gas pressure applied to the anti-seepage layer is not greater than 0.75kPa. The exhaust layer should be made of coarse-grained porous material with a particle size of 25-50mm, the permeability coefficient is required to be greater than 1×10-2cm/s, and the thickness is not less than 30cm. The gas drainage layer can also use a geocomposite drainage network with equivalent drainage performance.
2) Anti-seepage layer: The anti-seepage layer should be constructed with a composite geotechnical anti-seepage layer of geomembrane and geotextile.
High-density polyethylene (HDPE) or linear low-density polyethylene geomembrane (LLDPE) with a thickness greater than 0.75mm should be selected, and the permeability coefficient should be less than 1×10-7cm/s. However, geotextiles should be provided on the upper and lower surfaces of the geomembrane.
Benefits
The role of Heavy Duty Pond Liner for salein landfill：
- Reduce the infiltration of rainwater and other external water into the garbage dump to achieve the purpose of reducing landfill leachate
- Control the odor emission of the landfill and the release and collection of combustible gas from the upper part of the landfill in an organized manner to achieve the purpose of pollution control and comprehensive utilization;
- Inhibit the reproduction and spread of pathogenic bacteria and their spreaders, mosquitoes and flies;
- Prevent surface runoff from being polluted, avoid the spread of garbage and its direct contact with humans and animals;
- Prevent soil erosion;
- Promote the stabilization of the garbage heap as soon as possible;
- Provide a surface that can be landscaped, provide soil for vegetation to grow, facilitate reuse of landfill, etc.
Layout
- Before laying geomembrane, the corresponding qualified acceptance certificate documents of civil engineering should be obtained.
- Before the geomembrane is cut, its relevant dimensions should be accurately measured, and then cut according to the actual size. Generally, it is not suitable to cut according to the size shown in the figure. It should be numbered one by one and recorded in detail on the special form.
- When laying geomembrane, less welds should be sought, and raw materials should be saved as much as possible under the premise of ensuring quality. At the same time, it is easy to guarantee the quality.
- The lap width of the seam between the film and the film isgenerally not less than 10cm, and the welding seam is usually arranged parallel to the larger slope, that is, along the slope direction.
- Usually in corners and deformed areas, the length of the seam should be shortened as much as possible. Except for special requirements, on slopes with a slope greater than 1:6, within 1.5 meters from the top slope or the stress concentration area, no welds should be provided as much as possible.
- During the laying of the geomembrane, artificial folds should be avoided. When the temperature is low, it should be tightened as much as possible and paved.
- After the geomembrane is laid, walking on the membrane surface, moving tools, etc. should be minimized. Any objects that can cause harm to the anti-seepage membrane should not be placed on the membrane or carried on the membrane to avoid damage to the membrane. cause accidental damage.
