Product Description

It adoptsthedesign ofdense grooves with large inside and small outside , and when buried, the groove faces downwards, so that the water flow is sucked into the capillary aqueduct from bottom to top.Then the soil particles will not enter the capillary aqueduct with the water flow due to the natural precipitation of gravity, and there will be no siltation near the inlet ditch.
However, the internal grooves can not only enter water, but also leak water. The capillary drainage board will uses surface tension to make the water seal on the grooves without back leakage.When water enters, capillarity will have a suction effect on the water in the soil until it is filled and then discharged by gravity.When the water reaches the outlet, it will produce a siphon effect due to the drop, which will further generate negative pressure inside the soil, which greatly increases the suction and drainage effect.
Advantages:
No siltation: Usenatural gravity to separate soil and water;
High permeability:*0% open hole rate has effective water absorption area;
High drainage efficiency: drainage board using capillary force to improve drainage efficiency;
Strong anti-earth pressure:The arch bridge structure design can effectively disperse the stress distribution;
No filter:It has self-cleaning function and can cover soil directly without filter layer；
Convenient construction：Roll-type packaging does not take up volume, reducing transportation, storage, and does not require joints to improve efficiency.
Flexibly:can fit with the topography;
Good durability:It is made of PVC high density polymer material, which has good UV resistance and durability;
The width is generally 1m, 2m, 3m, the regular length is *5m or *0m, and special lengths are supported.
