Can the three-dimensional composite drainage network prevent siltation?

The three-dimensional composite drainage net is a commonly used material in major projects. So, can it prevent siltation?

I. Material properties and anti-siltation mechanism

The three-dimensional composite drainage net is made of a three-dimensional plastic net with a double-sided bonded permeable geotextile, so its drainage performance is very good. Its core is the three-dimensional geonet core, which contains a thick vertical rib and an inclined rib at the top and bottom to form an efficient drainage channel. The cross-arranged ribs can not only enhance the stability of the structure, but also prevent the geotextile from being embedded in the drainage channel, and maintain high drainage performance even under high loads.

Therefore, it can quickly drain water during drainage, and can also use the anti-filtration effect of the geotextile to prevent soil particles from entering the drainage channel, which can prevent siltation. The three-dimensional composite drainage net also has good corrosion resistance and acid and alkali resistance, so its service life is relatively long.

II. Working principle and application examples

In practical applications, the three-dimensional composite drainage net can solve the drainage problems in roads, roadbeds, tunnels and other projects through its unique drainage mechanism. For example, in road projects, laying it under the road surface can quickly drain the moisture in the road surface structure and prevent moisture from penetrating into the roadbed, causing the roadbed to soften or damage. Its anti-filtration effect can also prevent roadbed soil particles from entering the drainage system and keep the drainage channel unobstructed.

In landfills, it can not only serve as a groundwater drainage layer to quickly drain the groundwater in the landfill, but also as a leachate collection and drainage layer to collect and discharge the leachate generated during the landfill process. In this process, its composite use with non-woven geotextiles can enhance its anti-clogging ability, ensure the orderly discharge of leachate, and avoid environmental pollution caused by clogging.

As can be seen from the above, the three-dimensional composite drainage net can prevent clogging. It can not only solve the drainage problems in roads, roadbeds, tunnels and other projects, but also play an important role in special environments such as landfills.
