Product Details

The comprehensive solution of capillary drainage pipe method is to implant a drainage system composed of drainage materials with capillary function that do not clog in the soil. Using specialized technology for rapid non-destructive detection to investigate the water damage status of soil. Based on specific design theories for drainage pipes, an integrated innovative technology is developed to diagnose slope diseases in railway and other transportation engineering, design schemes and construction techniques for poor drainage of railway embankments, embankments, and station yards, in order to ensure the stability of transportation engineering quality and improve safety factors.

Application:
The first generation of drainage pipes is designed with grooves that are large inside and small outside, with a cross-section in the shape of "Ω";

(1) When the soil is full of water, under the action of capillary force, the water flow is sucked into the water channel, and the soil and water automatically separate;

(2) When the water flows out, a siphon effect is formed inside the water channel, creating negative pressure on the water in the soil. The water accelerates into the water channel and circulates repeatedly;

(3) Due to the small inlet of the trench, under the surface tension of water, the water flow will not flow out of the guide channel.

The first generation capillary drainage pipe "Ω" is made of weather resistant PVC material and added with anti-aging, acid and alkali corrosion resistance, and high and low temperature resistance (positive and negative 50 degrees) performance, with a service life of 20 years.
