How It Works: Trench Drain

The strip, channel, slot, linear, and line are the different types of trench drain. These structures are modeled after the floor drain. They typically are shaped with a dominate trough or channel. Their main purpose is to get rid of surface water, or help in the containment process of utility lines or chemical spills.

These units work by using their solid cover or grating, which is set to align flush with an adjoining surface. Most of these structures are constructed with concrete. They may also include channel formers, or metal or polymer liners.

These structures are known for having very narrow widths and very long lengths. Int heir cross-section there is a function for the maximum flow of volume that is to come off of nearby surfaces. Channels vary in size. They may be up to two feet wide and four feet deep.

French units are different from these units. The design is drafted with the purpose of removing ground water and incorporates perforated pipes. The common trench system types: linear, former, precast and cast in place. The standard type is the cast-in-place models.

Cast-in-place units include trenches made primarily from concrete. They are installed in the ground using reinforcing bars and wooden forms. Former models are similar to cast-in-place models, but they do not require the production of new forms. Precast models are good when in a time crunch. After the trough has been duh, the unit can be quickly installed and used. A more popular option of today are linear systems. Though they are made using plastic, polymer concrete, fiberglass, or steel, they do not have a lot of strength and are usually coupled with asphalt or concrete bodies for support.

Trench drains are floor drains. They include a channel-shaped or dominant-trough body. Their primary purpose is to rapidly and efficiently remove surface water or, help with containment of chemical spillage or utility lines.
