How to Fix Geocell on Slope Protection Projects?
When HDPE Geocells are used on slope protection projects, the reinforcement is very important. In this article, I will show you the full information of Geocell slope protection reinforcement. First is the material that we will use to fix Geocell on a slope. Second, we should know the length & space requirements for the Geocell pins. Third, I will recommend 2 ways that how to fix Geocells on the top of the slope. In the end, we should use tendons on very steep slopes. Let’s start now.
1, Use what to fix the Geocells on the slope?
You have 2 choices, one method you can use 12-14mm rebar as the anchor and use our anchor head together, please check the photos of our anchor and anchor head.
Or you can use J-pin directly, we don’t supply J-pin, you can buy 12-14mm rebar in your local market, and then ask the manufacturer to produce them into J-shaped. Use J-pin, then no need to buy anchor head. Most of our customers in South-east Asia use J-pin directly, they don’t buy anchor head.
2, The length and space requirements for Geocell Pin
The length and space requirements for Pin should based on the slope rate and soil property, we have a standard for this, please check the details I organized below.
3, From where to fix?
For Geocells used on slope protection projects, it is better to design a trench or deadman at the top of the slope. As in below photo:
If not have a trench or deadman design, to prevent landslides in the future, we’d better lay more area on the top of the slope, our engineer said for a 1:1 slope it is better to lay 80cm on the top, at least 40-50cm. As I marked on below photo:
4, Use Tendons on steep slopes.
On a steep slope, it is better to use Tendon. The durable Nylon tendon is very helpful in securing panels in place. Geocell panels include two slots designed to aid in attaching and feeding tendons through the panel walls. Tendons run through the length of each panel to help affix panels to the side of the slope for a more secure installation.
