Our flagship product, the White Road Bridge Special 3D Composite Drainage Net, represents the forefront of technology in infrastructure and environmental conservation. Specifically designed to optimize drainage efficiency and ensure structural stability, this product meets the stringent demands of modern civil engineering projects.
Geodrainage mesh is a type of geomaterial used in drainage systems, usually made of polymer material, with a porous mesh structure. It is designed to provide effective water discharge and drainage in underground works. These grid structures disperse water pressure and promote the flow of water, thus avoiding water retention in the soil, helping to stabilize the soil and prevent the water table from becoming too high. Geotechnical drainage net is usually used in roadbed, retaining wall, riverbank engineering and other civil engineering that needs drainage.
The core of the drainage net has two or three ribs. Our company uses three ribs, that is, 3D composite drainage net core.
The Role of 3D Composite Geodrainage Net
（1）laid between the foundation and the base, used to discharge the water between the foundation and the base, capillary water and effectively combined into the edge drainage system. This structure automatically shortens the drainage path of the foundation, greatly reduces the drainage time, and can reduce the use of selected foundation materials, which can extend the service life of the road.
（2）laying three-dimensional composite drainage net on the base can prevent the base fine material from entering the base, that is, playing an isolation role. The aggregate base will enter the upper part of the geonet to a limited extent. In this way, the composite geotechnical drainage net also has a potential role in limiting the lateral movement of the aggregate base, in this way, its role is similar to the reinforcement of the geogridging. In general, the tensile strength and rigidity of the composite geodrainage net are better than many geogates used for foundation reinforcement, and this limiting effect will improve the supporting capacity of the foundation.
3D Composite Geodrainage Net Advantages
（1）Powerful drainage function: the integrated drainage core layer can effectively remove the water inside the soil, reduce the water pressure in the soil, and prevent the adverse effects caused by soil liquefaction and water retention.
（2）Excellent isolation and protection function: combined with the isolation performance of geotextile or geomembrane, effectively prevent the mixing between different soil layers and protect the base and superstructure.
（3）Improve soil stability: By promoting water flow and reducing the amount of liquid water in the soil, it helps to improve the stability and carrying capacity of the soil.
（4）Flexibility and wide applicability: According to different engineering needs and geological conditions, different material and structure combinations can be selected for various engineering scenarios.
（5）Convenient construction: easy installation, can be prefabricated or laid on site, saving construction time and labor costs.
（6）Environmentally friendly: The use of environmentally friendly materials, less impact on the surrounding environment, help to protect the natural ecology.
In summary, the 3D composite geodrainage net integrates drainage, isolation and protection functions in one, providing a comprehensive soil protection and drainage solution, suitable for a variety of civil engineering projects.
Comparison of Different Standards of Composite Drainage Net
This comparison is to compare two kinds of composite drainage networks under different standard rules, and explore their differences in carbon black content, flexion strength, water conductivity, density and other aspects. Through the discussion of these two standard rules, we can deeply analyze and compare the composite drainage network, and we can understand their characteristics, advantages and limitations more comprehensively.

Test experiment procedure：
Construction Process of 3D Composite Geotechnical Drainage Net
First, ground preparation
Construction environment inspection: Before the drainage net is laid, the ground must be cleaned and removed of debris to ensure that the ground is flat, without adhesion and oil; Check the construction environment to ensure that the construction area is dry and smooth, and that there are no sharp objects or sharp surfaces that may damage the drainage net.
Preparation before construction: prepare the necessary drainage net materials and tools according to the design requirements and construction drawings; Next, it is necessary to carry out the preparatory work such as elevation positioning, pile foundation setting and excavation of dredging hidden pipe. Also ensure that the construction personnel have the relevant skills and experience.
Second, drainage pipe installation
The next step is to install the drainage pipe. In the installation process, special attention needs to be paid to the details of the slope, connection and flushing of the drainage pipe. After installation, static pressure test and leakage test are also required to ensure installation quality.
Third, three-dimensional composite drainage net laying rules
The core part of the whole construction is the laying of 3D geotechnical composite drainage net. During the laying process, it is necessary to pay attention to the expansion and docking of the grid to ensure that there is no wrinkle and net leakage at the splicing place, and to ensure that the net surface is stable and smooth. Strictly follow the following rules:
(1) The 3D geotechnical composite drainage net shall be laid in strict accordance with the geotechnical composite material layout design on the tender;
(2) The equipment for the construction of 3D geocomposite drainage net cannot work on the geosynthetic materials that have been laid. When paving the 3D geotechnical composite drainage net, the outdoor air temperature can not be lower than -5 degrees or higher than 40 degrees;
(3) All exposed 3D geocomposite drainage net edges must be pressed with sandbags or other heavy objects. In this way, the geotechnical composite drainage net can avoid being blown up by the wind and pulled out of the surrounding anchoring ditch. It is necessary to avoid the deployment of geotechnical composite drainage net in strong winds to prevent wind blowing;
(4) The laying, pulling, lifting or rolling of the 3D geocomposite drainage net must be controlled, and some uncontrolled expansion methods such as "free fall" are not allowed, and the laying method must ensure that the geocomposite drainage net and any other underlying geomaterials are not damaged;
(5) The layout of the 3D geotechnical composite drainage net must ensure that it will not cause folding or folding of the geotechnical composite drainage net or the direct geotechnical materials below, which will cause the arch of the geotechnical materials;
(6) Construction personnel should protect the geotechnical materials that have been laid to avoid damage that may be caused by construction machines. Any damage to 3D geocomposites or other geocomposites made for the above reasons must be repaired;
(7) When the 3D geotechnical composite drainage net is placed on the slope with a slope slope greater than 10%, the slope direction should be minimized to reduce the number of transverse overlap, and all 3D geotechnical composite drainage nets must be at least 1.5 meters above the slope foot;
(8) During the construction of 3D composite geotechnical drainage net, there should be no damage to the underlying geotechnical materials or things blocking the drainage net, such as mud, dust, dirt and debris;
(9) After the construction of the 3D geotechnical composite drainage net, the construction personnel and engineers must conduct a thorough inspection to ensure that there are no sharp things that damage the geotechnical material under the composite drainage net to cause damage or defective joints.
Fourth, joint treatment
Once the 3D geocomposite drainage net is laid, the joint needs to be treated. The joints need to be cut and reinforced to ensure sealing and firmness. The specific joint treatment method will vary depending on the material and specifications.
Fifth, construction records
Record important construction details, such as connection points, fixed positions, cut dimensions, etc., to assist in post-construction inspection and maintenance.
Sixth, surface dressing
Finally, it is necessary to finish the surface of the 3D geocomposite drainage net. The cleaning and finishing work is aimed at making it look flat and beautiful. You can choose to spray the surface layer or directly apply the protective layer method to finish the surface.
Seventh, quality acceptance
After the drainage net is laid, a comprehensive quality acceptance is carried out to check whether the connection, fixing and flatness of the drainage net meet the requirements.
