Draadbarrières

Draadbarrières, also known as wire barriers or cable barriers, are a type of safety device used primarily on roadways to prevent vehicles from crossing into oncoming traffic or leaving the roadway. They consist of a series of posts, typically made of steel, that are anchored into the ground or median. Wires, usually made of high-tensile steel cable, are then strung between these posts under tension. When a vehicle impacts the barrier, the cables absorb energy by deforming and stretching, helping to redirect the vehicle back into its original lane or slow it down more gradually than a rigid barrier.

The effectiveness of draadbarrières lies in their ability to absorb and dissipate kinetic energy. Unlike concrete or steel barriers that can cause significant damage to vehicles upon impact, draadbarrières are designed to be more forgiving. They are particularly useful in preventing head-on collisions on divided highways and can also be used to delineate pedestrian walkways or protect sensitive areas. Installation typically involves driving the posts into the ground at predetermined intervals, followed by the threading and tensioning of the cables. Maintenance involves inspecting the cables and posts for damage after impacts and re-tensioning or replacing components as needed. The design and strength of draadbarrières are engineered to meet specific safety standards and road conditions.
