什么是 GFRP 钢筋？
Glass fiber reinforced polymer (玻璃钢) rebar is an alternative reinforcing bar to traditional steel rebar. Unlike traditional steel rebar, which is made of carbon steel, 玻璃钢 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.

- Stronger than steel
- 轻的
- 需要更少的混凝土覆盖
- 比钢的使用寿命更长

GFRP地锚的性能和规格
Temporary 玻璃钢 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 玻璃钢 ground anchors possess safe working loads of up to 150 kilonewtons(kN) and are resistant to both acidic and alkali soil conditions.
轻松移除且风险最小
Crucially, temporary 玻璃钢 ground anchors can be easily cut and removed using piling, excavation, and tunnel boring machines without the risk of damage or program delays.
此功能为开发商和承包商提供了便利，简化了施工流程并最大限度地减少了潜在的挫折或项目延迟。
Using GFRP in Tunneling Projects
In tunneling, soft-eye applications refer to the use of 玻璃钢 (Glass Fiber Reinforced Polymer) elements, such as bars or tendons, to reinforce and support the excavation face of a tunnel during construction. 玻璃钢 bars are typically installed in a radial pattern around the periphery of the tunnel face and anchored into the surrounding ground. Additionally, 玻璃钢 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.
