Plastic drainage ditch
The main material of Plastic surface drainage ditch is HDPE (High-Density Polyethylene). They are primarily used for collecting surface water and directing rainwater into municipal drainage networks. These channels feature high strength, corrosion resistance, aging resistance, easy installation, cost-effectiveness, and eco-friendly recyclability, making them highly popular in European, American, and Australian markets. They are widely applied in urban streets, residential squares, parking lots, parks, ports, airports, green landscapes, building platforms, and other fields.
The Plastic Drainage Channel is an essential solution for modern water management, designed to efficiently collect and direct surface water away from streets, industrial areas, and residential properties. Made from high-quality, durable plastic materials, this channel is resistant to corrosion, chemical damage, and extreme weather conditions, ensuring long-term reliability and performance. Its lightweight construction allows for easy handling and installation, while modular designs provide flexibility to cover various drainage lengths and layouts.
The channel features a smooth internal surface that promotes rapid water flow, reducing the risk of clogging and water accumulation. It is compatible with different types of grates, including steel, plastic, or composite, to meet aesthetic and functional requirements. Ideal for urban infrastructure projects, parking lots, sidewalks, garden landscapes, and industrial facilities, the plastic drainage channel supports sustainable water management and prevents flooding or water damage.
Maintenance is simplified thanks to its modular design and accessible structure, allowing for quick inspection, cleaning, or replacement of components. Additionally, the plastic drainage channel is lightweight, cost-effective, and environmentally friendly, reducing installation labor costs and the environmental footprint compared to traditional concrete channels.
By combining durability, flexibility, and efficiency, the Plastic Drainage Channel provides a reliable solution for both commercial and residential drainage needs, ensuring long-lasting performance, improved safety, and effective water management in a wide range of applications.

The first step is to determine the size of the trench excavation

The second step is the concrete structure
When the concrete structure of section H reaches the required height and the load-bearing grade reaches E600-F900, 8mm steel bars should be used to make 15cm x 15cm grid structure reinforcing bars for section H. In this step, it is necessary to design an appropriate inclination for the water inlet on both sides of the drainage ditch.

The third step is the layout of the trench body
Starting from the installation of the water outlet, fix the bottom first to facilitate the pouring of the concrete on the side. For Part S, select the appropriate size according to the requirements of the design drawing. The completed surface of the drainage ditch is recommended to be 3 to 5mm lower than the completed surfaces of both sides of the ground, and the maximum height must not exceed the height of the completed surface of the ground. Pre-install the selected cover plate to prevent deformation of the trench body due to pressure from the concrete structure. As in the second step, the concrete structure on the side also needs to be reinforced (reinforcement bars are required for those with a load-bearing grade of E600 and above).

The fourth step is to decorate the surface (such as floor tiles, etc.
If a decorative surface needs to be laid, it must be 3 to 5mm higher than the horizontal plane of the trench.
