3D composite drainage nets in road construction offers a myriad of advantages that significantly enhance the overall performance and durability of infrastructure projects. Today let's explore the detail advantages of 3D composite drainage nets in road construction.
What is 3D composite drainage net
3D Composite drainage net is a type of geosynthetic drainage material. Fabricated using high-density polyethylene (HDPE) through a specialized extrusion molding process, these materials exhibit a unique three-layer structure. The central rigid ribs, arranged longitudinally, form drainage channels, while the vertically arranged ribs above and below provide support to prevent geotextile embedding in the drainage channels. This design ensures that even under high loads, the composite drainage net maintains excellent drainage performance. When used in conjunction with double-sided adhesive permeable geotextiles, it demonstrates comprehensive functionality encompassing "filtration-reinforcement-drainage-aeration-protection," making it the most optimal drainage material currently available.
3D Composite drainage nets are primarily employed in drainage projects for railways, highways, tunnels, municipal engineering, reservoirs, slope protection, and other infrastructural developments, this material yields remarkable results.
Product Features:
1, Excellent drainage performance (equivalent to a one-meter thick gravel drainage).
2, High tensile strength.
3, Reduced probability of geotextile embedding into the core, ensuring long-term stable drainage.
4, Endures prolonged exposure to high-pressure loads (capable of withstanding compressive loads of approximately 3000 kPa).
5, Corrosion-resistant, withstands acidic and alkaline conditions, and boasts a long service life.
6, Convenient construction, shortened project timelines, and cost-effectiveness.
Functions and Characteristics of Composite Drainage Net:
As we can see from the above picture, because of its unique structures, the Composite Drainage Net serves multiple essential functions and possesses distinctive characteristics in various construction scenarios.
1, Installed between the subgrade and the base, the composite drainage net is designed to drain accumulated water between the subgrade and the base, blocking capillary water and effectively integrating into the edge drainage system. This structure automatically shortens the drainage path of the subgrade, significantly reducing drainage time. It also allows for a reduction in the quantity of selected subgrade materials, enabling the use of materials with more fines and lower permeability. This can extend the lifespan of the road.
2, Installing a drainage net in the base layer prevents fine base materials from entering the subgrade layer, acting as a barrier. Aggregate base materials may enter the upper portion of the geosynthetic net to a limited extent. In this way, the composite geotechnical drainage net has the potential to restrict lateral movement of the aggregate base layer, providing reinforcement similar to that of geogrids. Generally, the tensile strength and rigidity of composite geotechnical drainage nets surpass many geogrids used for subgrade reinforcement, enhancing the support capacity of the subgrade.
3, After road aging and crack formation, most rainwater tends to enter the cross-section. In such cases, laying the drainage net directly beneath the road surface, instead of a drainable subgrade, allows the net to collect moisture before it penetrates the subgrade/base layer. Moreover, adding a membrane to the bottom of the drainage net further prevents moisture from entering the subgrade. For rigid road systems, this structure allows for the design of roads with a higher drainage coefficient (Cd). Another advantage of this structure is that it may enable more uniform hydration of concrete (research on the extent of this advantage is ongoing). Regardless of whether it's a rigid or flexible road system, this structure can extend the road's lifespan.
4, In northern climate conditions, laying the drainage net helps mitigate the impact of frost heave. If the freezing depth is considerable, the geosynthetic net can be placed in a shallower position within the base, acting as a barrier against capillary action. Additionally, it may be necessary to replace the easily frost-heaving granular base layer, extending downward to the freezing depth. The frost-susceptible backfill can be placed directly on top of the drainage net, up to the ground level. In such cases, the system can be connected to a drainage outlet, allowing the groundwater level to be at or below this depth. This potential limitation on ice crystal development can help lift traffic load restrictions during the spring thaw in cold regions.
