Turbidity Curtain Anchoring
How to Anchor a Type 2 Turbidity Curtain
Question: We are wanting to anchor a type 2 turbidity curtain and were wondering, is there a typical way to anchor this barrier, possibly at the top eyebolt? If not, where would we need to anchor the turbidity curtain?
Answer: Anchoring is a common requirement for any Type 2 or Type 3 Moving Water Silt Curtain. Designed to stabilize the barrier into position, these products provide a reliable way to contain silt and prevent the spread of materials around your location.
Since curtains are not designed to touch the bottom floor of a location, anchoring procedure will involves anchoring from an adjacent buoy to the anchor point on the curtain. This provides your site with all the necessary equipment for anchoring and securing a barrier into position. To achieve this process, each kit will include the following:
- Painter Rope
Anchor Positioning for Turbidity Curtain Installation
The typical anchoring process used for these barriers is a system that involves attaching the bottom chain of a curtain to various anchoring points. This type of anchoring allows for turbidity curtains to be kept in place without any additional strain being placed on this curtain itself. The standard installation will involve the following:
- Attached the Painter Rope from the Buoy to the Barrier
- Move the Buoy Slightly Away from the Barrier
- Lower the Anchor into the Water
- Optional: If a trip line is being used, lower the anchor with the line attached so it will remain in place.
There are anchor systems available for a each of our turbidity curtains. Anchor kits have been used with any of the following:
Best Management Practice is for Turbidity Curtain to be anchored every 50 feet or every 100 feet, depending on environmental conditions on site. Spacing of 50 feet is generally used for non-tidal conditions with 10-15 feet of depth or tidal water conditions. Non-tidal conditions without this depth can be every 100 feet.
