ما هي حديد التسليح GFRP؟
Glass fiber reinforced polymer (GFRP) rebar is an alternative reinforcing bar to traditional steel rebar.
Unlike traditional steel rebar, which is made of carbon steel, GFRP rebar is composed of high-strength glass fibers embedded in a polymer resin matrix.
This material offers several advantages over steel rebar, including corrosion resistance, high strength-to-weight ratio, electromagnetic neutrality, and non-conductivity.

خصائص ومواصفات المراسي الأرضية GFRP
Temporary GFRP ground anchors are 25% lighter than conventional steel strand anchors while exhibiting twice the strength. They can be installed using the same construction methods as their steel counterparts and maintain similar diameters and strand quantities.
These GFRP ground anchors possess safe working loads of up to 150 kilonewtons(kN) and are resistant to both acidic and alkali soil conditions.
إزالة سهلة والحد الأدنى من المخاطر
Crucially, temporary GFRP ground anchors can be easily cut and removed using piling, excavation, and tunnel boring machines without the risk of damage or program delays.

Using GFRP in Tunneling Projects
In tunneling, soft-eye applications refer to the use of GFRP (Glass Fiber Reinforced Polymer) elements, such as bars or tendons, to reinforce and support the excavation face of a tunnel during construction. GFRP bars are typically installed in a radial pattern around the periphery of the tunnel face and anchored into the surrounding ground.
Additionally, GFRP bars are generally softer and less abrasive than steel reinforcement, making them easier to cut with tunnel boring machines (TBMs) equipped with cutting tools. This property reduces wear and tear on the TBM’s cutting tools, leading to lower maintenance costs and minimizing the risk of damage to the equipment.
