What material is better for U-shaped drainage channels? What are their advantages?

The main functions of drainage channels are drainage and diversion, and they are commonly used in urban roads, parks, squares, residential areas, and other places. They can be well hidden underground with a smooth surface. The accompanying cover plates have appropriate gaps to prevent debris from entering the channel and blocking it, while allowing surface water to flow into the drainage channel and be directed for drainage.

As the demand for urban aesthetics continues to rise, drainage channels are being widely used and their appearance is becoming more appealing. Let’s take a look at the shapes of drainage channels.

Resin drainage channels: Relatively heavy and durable.

PE drainage channels: Lighter, cheaper, made of plastic.

You can choose different materials based on your needs.

Both materials are easy to construct. The two drainage channels can be connected together using the interlocking mechanism at both ends.

So what are the advantages of drainage channels that make them widely used in landscape construction? Here are some points to consider:

1. Sturdiness and high bending strength: Resin concrete can absorb external impact, and its compressive and bending strength is higher than traditional concrete.
2. Chemical corrosion resistance: Heavy-duty drainage channels can resist the erosion of chemicals, have high resistance to acid and alkali, and are highly corrosion-resistant. They can withstand the erosion of biologically generated sulfuric acid and acidic soil.
3. High temperature resistance and freeze-thaw resistance: They can withstand sunlight exposure and the effects of freezing and thawing without any impact on the material structure. They have good climate adaptability and will not become brittle or damaged even in harsh environments.
4. Easy construction and cost-saving: The construction of these channels is convenient, with shallow trench depth and simple slope adjustment. They are easy to install, and the construction speed is fast, ensuring project completion within the scheduled timeframe.
5. High impermeability: Resin concrete has a lower water absorption rate compared to wood and cement.

Based on these advantages, drainage channels are gradually replacing traditional cement channels and are favored in landscape construction. Let’s take a look at the overall effect in the provided image.
