The three-dimensional composite drainage net is a material commonly used in drainage projects such as landfills, roadbeds, and tunnel inner walls. It has good drainage performance. So, can it prevent siltation?
1. Structural characteristics of the three-dimensional composite drainage net
The three-dimensional composite drainage net is a geosynthetic material made of random wire melt-laid net. It consists of a three-dimensional plastic mesh core with double-sided adhesive permeable geotextile. It has a unique three-layer structure: the middle ribs are rigid and arranged longitudinally to form a drainage channel; the ribs arranged crosswise up and down form a support to prevent the geotextile from being embedded in the drainage channel. Therefore, it can still maintain efficient drainage performance when subjected to high loads.
2. Working principle of the three-dimensional composite drainage net
The working principle of the three-dimensional composite drainage net is mainly based on its unique drainage channel and support structure. When rainwater or sewage penetrates the soil cover layer, the three-dimensional composite drainage net can quickly collect it and discharge it in an orderly manner through the drainage channel. Its support structure can prevent the geotextile from being embedded in the drainage channel, which can ensure that the drainage channel is unobstructed.
3. The anti-siltation mechanism of the three-dimensional composite drainage net
The anti-siltation mechanism of the three-dimensional composite drainage net is mainly reflected in the following aspects:
1. Large opening density: The three-dimensional composite drainage net has a large opening density, which allows water to flow smoothly and reduces the possibility of siltation.
2. High pressure resistance: It has high pressure resistance and can keep the drainage channel unobstructed even under very high loads, which can prevent siltation.
3. Composite use with non-woven geotextiles: After the three-dimensional composite drainage net is composited with the non-woven geotextile, it can discharge the collected rainwater or sewage in an orderly manner under the buried closed cover layer without forming siltation. This composite use method can not only improve drainage efficiency, but also avoid sliding problems caused by water saturation of the soil cover layer.
From the above, it can be seen that the three-dimensional composite drainage net has a good anti-siltation performance. Whether it is a landfill, roadbed or tunnel inner wall and other drainage projects, it can be used for drainage and anti-siltation.
