GROUND SLEEVE - THE SOLUTION FOR BARRIERS INSTALLED ON A TERRAIN ROAD EDGE
GROUND SLEEVE - THE SOLUTION FOR BARRIERS INSTALLED ON A TERRAIN ROAD EDGE
GroundSleeve is a metal finned reinforcement system that has the purpose of involving a greater volume of ground to have a high resistance in the event of a vehicle impact on the guardrail.
GroundSleeve complies with the EN 1317-5 standard since, by intervening only on the terrain, it does not modify the geometric and mechanical characteristics of the certified barrier.
Therefore GroundSleeve DOES NOT REPRESENT A PRODUCT MODIFICATION.

Where is it installed?

Inserted into the road mantle to guarantee the constant performance of the barrier;
The depth of insertion corresponds to the position of the plastic yield point defined during the crash test;
GroundSleeve can also be installed on existing barriers.
How is it sized?

GroundSleeve is sized according to the type of barrier and the characteristics of the site, in particular the distance between the finned plate and the U-bolt connecting the barrier pole;
For the sizing of each type, a FEM model was created in correspondence with the test result;
For verification, the test is carried out on site with the post of the project barrier and the installed system;
Verification of the correct formation of the plastic yield point and definitive evaluations.
ADVANTAGES OF GROUNDSLEEVE
ADVANTAGES OF GROUNDSLEEVE

Quick and easy installation of the system using a traditional “pile-driving machine” with the possibility of inserting a GroundSleeve even on the barriers already installed

Safeguard and legal protection for the managing body of the road infrastructure in the event of road accidents

STRATEC RT offers with the supply of the product the free processing, calculation and sizing of the GroundSleeve system

Optimal constraint at the base and formation of the yield point at an approximate height as during th Crash Test

In the event of a vehicle collision, the system always remains firmly fixed

Adaptability, both geometrically and structurally, to all posts sections on the market

FREQUENTLY ASKED QUESTIONS

Does the installation involve the use of special machinery or equipment?
The presence of a standard pile driver is sufficient which inserts GroundSleeve with a simple matrix into the road foundation.
Is it necessary to certify the barrier again after inserting the GroundSleeve System?
No. GroundSleeve simply increases the resistance of the ground and without modifying the technical characteristics and structure of the barrier it doesnt rapresent a product modification and does not require any certification.
Is it possible to intervene on already installed barriers?
Absolutely Yes.
The great advantage of the system is that it can also be installed on existing road barriers, restoring their safety.
Is it a very expensive system?
No, especially comparing it to the construction of the curb or to the type of cemented mix for the consolidation of the embankment.
