There is absolutely no question that an impeccably designed draining system for airports is a fundamental and perhaps, one of the most important requisites to ensuring operational integrity and safety. Moreover, an intelligently designed drainage network significantly enhances pavement durability and expedites getting rid of water in the face of a thunderstorm or torrential rain.
Design experts come up with the best channel drain system to prevent domestic and international airports to mitigate costly damages caused primarily by flooding. Moreover, a cutting-edge and error-free drainage system can also help the air traffic steer clear of potential hazards, especially during take-off and landing.
All airports need an appropriate trench drain system, which is reinforced and locked down with the use of bolts. Why? Well, that is because a loose bolt has the potential to be easily sucked into one of the plane’s engines, which could spark a huge disaster during take-off or in mid-air. All manner of airports, including county, domestic, international and municipal, more or less have reinforced and sturdy trench drains expanding across the entirety of the runway landscape.
A well-designed trench gate can considerably help avoid slope erosion and prevent the foundation of the runway pavement from being saturated and weakened.
It is important to understand that the drainage network or system for airport isn't a lot different compared to what you see on highways or on your street. This means, having a proper system installed requires the same methodologies. But because airports have a flat gradient in terms of land mass, it is necessary for the water to be removed from the subsurface as well as the actual surface as quickly as possible.
This is why airports require a highly integrated, cutting-edge and easy to maintain drainage systems, throughout the taxiways, runaways as well as the parking lots. Plus, a channel drain or a slot drain for airport water drainage must always be able to accommodate a large volume of water without the risk of extracting foreign contaminants.
The only way airport drainage system differs from that of what you see on the street is that structure and the drainage channel running along the landscape must be designed to eliminate the potential losses to the structural integrity of the runway that can be caused due to precipitation. This is why slotted drains have become intensely popular in airports.
These drains are designed to have slots between them. With no grates, these drainage systems have a higher rate of water drainage in an open area without leaving any debris or other things that may damage the runway or the planes taking-off or landing during a thunderstorm or even light showers.
Moreover, slot drains come in variety of materials. For high end durability and long-term sturdiness you can select stainless-steel drainage, galvanized steel and fiberglass. In addition, slot drains are also designed to be easily compatible and integratable with transition pits as well as elbows, making the installation process quick and less time-consuming.
