1. Compound Drainage plate Overview of the characteristics of
Composite drainage board consisting of one or more layers Non-woven geotextile Compounded with a layer of three-dimensional synthetic geonet core, it has excellent drainage performance, high strength, corrosion resistance and convenient construction. Its unique structural design allows water to be discharged quickly, and it also maintains the stability of the soil, which can prevent soil erosion and the rise of groundwater table. The composite drainage board also has very good tensile strength, compressive resistance and aging resistance, and can withstand loads in various complex environments for a long time.
2. Diversified uses of composite drainage boards
1、Foundation engineering drainage
In the construction of railway, highway, tunnel and other infrastructure, composite drainage board is commonly used in soft foundation treatment, subgrade reinforcement and slope protection projects. Its efficient drainage performance can quickly remove groundwater, reduce soil water content, improve foundation bearing capacity, and prevent subgrade settlement and slope instability.
2、Waterproof protection
The composite drainage board is used in combination with the waterproof layer to form a double waterproof and impervious system. It can protect the waterproof layer from soil backfilling, plant root penetration, acid-base erosion and underground insects and microorganisms, prolong the service life of the waterproof layer and ensure the safety of engineering structures.
3、Landscaping and roof greening
In projects such as roof gardens and outdoor garage roof greening, composite drainage boards not only have drainage functions, but also serve as an isolation layer between the soil and the structural layer to prevent plant roots from penetrating the structural layer and causing damage. Its good air permeability helps plant growth and improves greening effect.
4、Hydraulic engineering
Composite drainage board is also widely used in water conservancy projects such as reservoirs, dikes and revetments. It can quickly remove storm water and groundwater, lower water level, enhance the stability of dikes, and prevent flood erosion and erosion. Its corrosion resistance and durability also ensure reliability for long-term use.
5、Environmental Protection Engineering
In environmental protection projects such as landfills and sewage treatment plants, composite drainage boards can isolate pollutants and prevent leachate from contaminating groundwater and soil. Its high strength and corrosion resistance enable it to work for a long time under harsh environmental conditions and contribute to the cause of environmental protection.
As can be seen from the above, composite drainage board is a material commonly used in architectural engineering and civil engineering. It can be used in the fields of basic engineering drainage, waterproof protection, landscaping, water conservancy engineering and environmental protection engineering.
