3D composite drainage network: optimizing drainage management in landfills

With the acceleration of urbanization, garbage disposal has become a serious environmental problem. As the main method of urban garbage disposal, the performance of landfills directly affects the quality of the surrounding environment and ecological balance. The application of 3D composite drainage network in landfills provides a new solution for improving the performance of landfills.
I. Performance characteristics of 3D composite drainage network
3D composite drainage network is an innovative geosynthetic material with excellent drainage performance, high strength, corrosion resistance, aging resistance and other characteristics. Its unique three-dimensional structural design and high permeability enable it to rapidly guide water flow in landfills, preventing water accumulation and thus protecting the dryness and stability of the landfill.

III.Application of 3D composite drainage network in garbage landfills

1.Drainage management: 3D composite drainage network can quickly guide the water flow in garbage landfills, prevent water penetration, and thus protect the dryness and stability of the landfill. At the same time, it can effectively discharge the methane produced by fermentation in the soil, preventing safety accidents such as explosions. 3D composite drainage network has excellent drainage performance and high strength, which can meet the high standards of garbage landfills.

2.Soil reinforcement: The high strength and shear strength of 3D composite drainage network enable it to reinforce the soil structure in the landfill, improve its load-bearing capacity and stability. This helps to prevent land subsidence and deformation, reducing the impact on the surrounding environment. The corrosion resistance and aging resistance of 3D composite drainage network enable it to maintain stable performance during long-term use.

3.Reduce environmental pollution: Through effective drainage management and soil reinforcement, 3D composite drainage network can reduce the pollution of garbage landfills to the surrounding environment. For example, it can prevent groundwater pollution, reduce odors and mosquito breeding, etc.

4.Improve landfill efficiency: Due to the rapid guidance of water flow by 3D composite drainage network, the landfill operation can be completed in a short time, improving the landfill efficiency. This helps to reduce the operating cost of the landfill and reduce the impact on the surrounding community. By improving the performance of garbage landfills, 3D composite drainage network helps to reduce the impact on the surrounding environment and promote environmental protection and sustainable development.

5.Easy installation: 3D composite drainage network has light weight and good flexibility, which can be cut and spliced according to needs. This makes installation simple and fast, without complicated construction techniques and equipment.

Jingbian County Urban Domestic Waste Landfill Phase I Project
The first phase of the Jingbian County Urban Domestic Waste Landfill covers an area of 62,476 square meters (approximately 93.7 acres), with a storage capacity of 104.0 cubic meters in the landfill area, an effective storage capacity of 1.029 million cubic meters, a landfill capacity of 300 tons per day, and a design service life of 10 years.
The landfill site adopts sanitary landfill technology to improve the environmental conditions of the original garbage dump site, making the residential area beautiful and clean, saving a lot of land, and improving the space utilization factor. At the same time, the project adopts artificial horizontal seepage prevention, and the bottom seepage prevention project of the reservoir area adopts a composite lining seepage prevention system, using polyester filament spunbond needle punched geotextile layer + HDPE artificial seepage prevention layer + GCL bentonite waterproof blanket + composite drainage network + compacted soil for seepage prevention, which can avoid the pollution of leachate to the surrounding surface water, groundwater and soil, reduce the damage to human health, save the cost of pollution control, reduce the economic loss caused by pollution, improve the satisfaction level of residents, and have good environmental and economic benefits.
The project covers an area of about 60,000 square meters. The seepage prevention project in the reservoir area is constructed by our company. It uses a composite lining and utilizes the three-dimensional composite drainage network produced by our company to guide, drain, and collect leachate, effectively avoiding pollution to surface water, groundwater, and soil.

The application of 3D composite drainage network in garbage landfills provides a new solution for optimizing the drainage management of landfills. Its high-performance, durable stability, easy installation, and environmental sustainability make it an ideal drainage material choice for garbage landfills. By using 3D composite drainage network, we can better address the environmental issue of garbage disposal and promote sustainable development in society.
