Floating Turbidity Curtains may vary dramatically in how they are specified, called out for or referred to by the several Departments of Transportations (DOT's) across our country. For instance several DOT's when specifying "Floating Turbidity Curtains" do not utilize the term "Floating", others replace the term "Silt" in place of "Turbidity" but others utilize "Barriers" rather than "Curtains". Therefore it's very common to see the following names by DOT's when talking about Floating Turbidity Curtains: Floating Turbidity Barriers, Turbidity Curtain, Turbidity Barrier, Silt Curtain, Silt Barrier. It is always good if all DOT's would agree to use the same verbiage as this would help make it less complicated for marine contractors as well as manufacturers like www.enviro-usa.com.
Several Types of Floating Turbidity Curtains
Type 1 Floating Turbidity Curtain is likewise identified as "Calm Water" or "Light Duty" with respect to the state that you are in and the verbiage most frequently employed by that states Department of Transportation (DOT). Type 1, Calm Water or Light Duty Floating Turbidity Curtains are most generally utilized as its name states. They are utilized for calm water or light duty applications. This means that there is little or no current at all, like in ponds, lakes and streams.
Type 2 Floating Turbidity Curtain is likewise known as "Moving Water" or "Medium Duty" depending on the state which you're in and the verbiage most commonly employed by which states Department of Transportation (DOT). Type 2, Moving Water or Medium Duty Floating Turbidity Curtains are most generally employed as its name states. They are used for moving water or medium duty applications. This implies that there is certain current such as rivers or ponds & lakes with strong wind conditions. The difference between the Type 1 (calm Water/Light Duty) and the Type 2 (moving water/Medium Duty) is which the Type 2 includes a top tension cable (above floatation) so as to make the Floating Turbidity Barrier stronger so that it can manage the loads utilized from the water movement as well as current.
Type 3 Floating Turbidity Curtain is also recognized as "Tidal" or "Heavy Duty" with regards to the state which you're in and the verbiage most generally used by that states Department of Transportation (DOT). Type 3, Tidal or Heavy Duty Floating Turbidity Curtains are most usually employed as its name states. They are utilized in tidal or heavy duty applications. The Type 3 is very generally employed for dredging projects, in marine construction in Ports and on beaches. The Type 3 Floating Turbidity Curtain possesses a few changes that make it useful for these applications. It has a bigger float and two cables instead of just one. The bigger float permits the Floating Turbidity Curtain to float and adapt itself to the water situations much better and the dual cable enables it to take care of the forces/loads better, whether or not the tide is coming in or going out.
