NOVELTY - An environmentally-friendly high-strength thermal-insulation planting pipe comprises an antibacterial layer as an innermost layer, a triangular grid layer, a heat-preservation layer, and a high-density polyethylene pipe layer as an outermost layer. The triangular grid layer forms a skeleton between the antibacterial layer and heat-preservation layer. USE - Environmentally-friendly high-strength thermal-insulation planting pipe is used in the form of round, square, trapezoidal and other irregular shapes (all claimed). ADVANTAGE - The environmentally-friendly high-strength thermal-insulation planting pipe has excellent sanitary index and comprehensive performance. The preparation cost of the planting pipe is low, and has good wood processing performance, reduces the damage caused by opening holes in pipelines, and improves the qualified rate of products. By using the physical antibacterial property of graphene coating, the planting pipe can effectively inhibit the growth of various microorganisms in the pipeline, and has a more efficient and durable antibacterial effect. The stability of the triangles on the triangular mesh layer is higher than other geometric figures, and the nodes formed by the crossing of carbon fibers make the mesh stronger, thus improving the strength of the pipes, and the carbon fibers can also make the pipes connect to each other after opening holes, and reduces cracking. The insulation layer reduces low temperature chilling damage and freezing damage to plants in winter.
