Three Dimensional Composites Drainage Network
Three dimensional composite drainage network is a new type of geosynthetics. It is made of a three-dimensional geonet core bonded with needle punched nonwoven geotextiles on both sides. It has a pure maintenance system, can drain underground water quickly and block capillary water under high load in construction,and it can also play the role of isolation and reinforcement.
Benefits
Drainage composites perform multiple functions at once, making them an excellent choice for landscaping and infrastructure projects. They provide a cost-effective alternative to traditional gravel drainage materials while still providing exceptional performance.
These innovative products are designed to withstand extreme conditions, with high resistance to chemicals and corrosion. This makes them an ideal option for construction projects in harsh environments, as they can withstand heavy loads and prolonged exposure to weather elements. As a result, they require minimal maintenance and repairs, saving you money in the long run.
One of the best things about composites is their longevity and durability. Unlike traditional drainage materials, which can deteriorate over time and require frequent replacement, composites are designed to last. They are also lightweight, which makes them easy to handle and transport. This results in a quicker installation process and reduced labor costs.
The three-dimensional composites drainage network core is made up of a thick vertical rib on both sides and inclined ribs on the top and bottom. It can absorb a large amount of compression load throughout the use process while maintaining a considerable thickness and exhibiting good water conductivity properties.
The drainage geocomposites are suitable for a variety of applications, such as landfill subgrade and pavement drainage, railway drainage, tunnel drainage, back drainage of retaining wall, garden and sports field drainage. They are particularly suited for colder climates where they can be laid as an underlay to mitigate frost heave, especially in the case of granular subbases that extend into freezing depths.
Applications
Three dimensional composites drainage net is a new type Drainage geonet of geosynthetic dewatering material, which is designed to complement or replace sand and gravel. It consists of a three-dimensional thick geonet composited with two needle punched non-woven geotextiles, which form a “filtration – drainage – ventilation – protection” overall performance and can replace traditional sand and gravel in many construction applications.
These products are a great alternative to French Drains and other conventional underground drainage systems. They have a high flow capacity, allow for directional flow and are easy to install. They are also corrosion-resistant, heat-resistant, and pressure-resistant to ensure the longevity of the product.
The gaps on the top and bottom of the core help to filter out impurities and prevent soil fines from clogging the surface. This helps to maintain drainage and reduce maintenance costs by reducing the frequency of blockage and cleaning work. Additionally, the core is made of a non-toxic material to protect water quality.
In landfill applications, these products are used for leachate collection layers and in mining for coal stack and embankment drains. They are also useful in the construction of road edge drains, airport pavements and railroad right-of-way. In these applications, the composite drains are typically placed between the road and the edge of the runway or highway pavement. These drains can be prefabricated or installed on site, and are able to withstand a high overloading pressure.
Installation
Drainage composites are designed to replace conventional granular layers in the subsurface of civil engineering projects. They offer a number of benefits including cost-savings, increased performance and ease of installation. They also provide excellent resistance to creep and corrosion and can withstand long-term high compression loads.
Typically, drainage composites are molded products that contain a series of perforated conduits (like perforated mini-pipes) regularly spaced across their width and sandwiched between two or more geosynthetics (often geotextiles). These materials offer a multifunctional solution by providing filtration, separation, and drainage functionality while protecting the structure from contamination.
A specialized type of drainage geocomposite is the prefabricated edge drain, which is placed in the vicinity of a highway pavement, airfield pavement, or railroad right-of-way for lateral drainage away from the pavement section. The purpose is to eliminate the need for traditional granular material and prevent the erosive effect of water on the foundation of the pavement and adjacent soil.
Three Dimensional Composites drainage network is a new drainage geocomposite which consists of one three-dimensional geonet heat-bonded to both sides with non-woven needle punched geotextiles. Its core has strong rigidity and is arranged longitudinally to form dewatering channel, the upper and lower fillets are support to avoid geotextile inserting into the dewatering channel. It can also keep good dewatering property under the high load in construction, block the capillary water and improve the supporting ability of foundation.
Maintenance
It is important to perform regular maintenance to ensure that the drainage system functions as designed. It is recommended that the drainage system be inspected in spring, fall and after significant rainfall events. Any drainage system issues should be promptly repaired to minimize any erosion control and water quality impacts. In PP plastic two-way geogrid addition, it is suggested that all outfalls be clearly marked and located above the water level to avoid ponding and surface water inlets.
Drainage geocomposites are used to supplement or replace sand, gravel and coarse aggregate in many civil engineering applications. They consist of a HDPE geonet heat-bonded to one or both sides with needle punched nonwoven filter geotextiles. They have a high water-flow capacity, especially at low overburden pressures and are ideal for leachate collection layers in landfill applications.
A composites drainage network has the ability to reduce the amount of contaminant and sediment that is carried through the City’s drainage systems, roadways and County roads into local receiving waters. In addition, the tensile strength and stiffness of the composite drainage grids will restrain the aggregate base layer and prevent it from moving horizontally within the sub-base. This will also improve the bearing capacity of the foundation. Moreover, a drainage network will improve the life of the roadway surface and extend the service life of the pavement.
