Hongyue plastic drainage board
Short Description:
- A plastic drainage board is a geosynthetic material used for drainage. It usually appears in a strip – like shape, with a certain thickness and width. The width generally ranges from a few centimeters to dozens of centimeters, and the thickness is relatively thin, usually around a few millimeters. Its length can be cut according to the actual project requirements, and the common lengths range from several meters to dozens of meters.

Structural Composition
- Core Board Part: This is the core structure of the plastic drainage board. There are mainly two shapes of the core board, one is the flat - plate type, and the other is the wave - type. The drainage passage of the flat - plate - type core board is relatively straightforward, while the wave - type core board, due to its special shape, increases the length and tortuosity of the drainage passage and can provide better drainage effects. The material of the core board is mostly plastic, such as polyethylene (PE), polypropylene (PP), etc. These materials have good corrosion resistance and a certain strength and can withstand a certain pressure without deformation, ensuring the smoothness of the drainage passage.
- Filter Membrane Part: It wraps around the core board and functions as a filter. The filter membrane is usually made of non - woven geotextile. The pore size of it is specially designed to allow water to pass through freely while effectively preventing soil particles, sand grains and other impurities from entering the drainage passage. For example, in the drainage project of soft soil foundation, if there is no filter membrane or the filter membrane fails, soil particles entering the drainage passage will cause the drainage board to be blocked and affect the drainage effect.

Application Fields
- Building Foundation Treatment: In construction engineering, for the treatment of soft soil foundation, the plastic drainage board is a commonly - used material. By inserting drainage boards into the foundation, the consolidation of the foundation soil can be accelerated and the bearing capacity of the foundation can be improved. For example, in the construction of high - rise buildings in coastal areas, due to the high groundwater level and soft foundation soil, the use of plastic drainage board can effectively drain the accumulated water in the foundation, shorten the foundation construction period and lay a good foundation for the stability of the building.
- Road Engineering: In road construction, especially in the treatment of soft soil subgrade, the plastic drainage board plays an important role. It can quickly reduce the groundwater level in the subgrade and reduce the settlement and deformation of the subgrade. For example, in the construction process of expressways, setting plastic drainage boards in the soft soil subgrade can enhance the stability of the subgrade and improve the service life of the road.
- Landscaping: The plastic drainage board is also applied in the drainage system of landscape architecture. For example, around large lawns, gardens or artificial lakes, the use of plastic drainage boards can timely drain excess rainwater, prevent the adverse effects of water accumulation on plant growth and also help to maintain the beauty and tidiness of the landscape.

Advantages
- High Drainage Efficiency: Its special core board structure and filter membrane design enable water to quickly enter the drainage passage and be smoothly discharged, having a higher drainage efficiency than traditional drainage materials (such as sand wells).
- Convenient Construction: The plastic drainage board is light in weight and small in volume, which is convenient for transportation and construction operations. During the construction process, the drainage board can be inserted into the soil layer through a special inserting machine. The construction speed is fast and it doesn't require large - scale construction equipment.
- Cost - effective: Compared with some other drainage solutions, the cost of the plastic drainage board is relatively low. It can ensure the drainage effect while reducing the drainage cost of the project, so it is widely used in many engineering projects.
