FRP( Short of Fiber Reinforced Plstic) is one kind of composite material made through the composite process with polymer resin as the matrix such as E-glass/basalt fiber or carbon fiber as the reinforcement. It has the advantage of high tensile strength, low weight, corrosion resistance and non-conductive than the steel rebars.
Glassfiber reinforced polymer rebar (GFRP) is made from high technical performance resin (UP/VE/EP/PU)and glass fiber by pultrusion process.
Compared with steel rebars, GFRP Fiberglass Rebar/Basalt Fiber Rebar have many advantages:
1. High tensile strength.
-Its strength is approximately double of steel bar, And when you bend it, it will bounces back quickly, that make the building more stable.
2. High corrosion resistance.
-Fiberglass rebar is waterproof and resistant to seawater corrosion, it never rust even stay in the concrete or building wall for many many years.
3. Low density and light weight.
-The meter weight is only 1/4 of steel bar, the worker can carry it easily, And also the transportation cost can be reduced much more.
4. Electrical insulation, without static electricity
-It has no electrical conductivity, and no sparks will be produced when being cut, it's particularly suitable for high risk gas zones; like Coal mines, oil fields.
5. Easy Cutting.
-Easy to cut, very suitable for construction of tunnels and subway projects, It avoids damages to cutter heads and does not delay excavation.
Applications:
Сonstruction,
subway tunnel,
coal mine tunnel,
rock surface anchoring,
sea wall,
parking structures,
slope support,
transportation industry and dam etc.
construction of the subway station always should be a deep foundation pit project, which needs to be constructed with a retaining wall. Then construction technology of underground continuous wall and retaining wall were widely used for temporary protection.
In the shield launching shaft and receiving shaft area of station, because the performance of glass fiber reinforcement is roughly the same as the shrinkage coefficient of concrete, and it can bond with concrete well, it has lower shear strength and higher tensile strength, and can be broken by shield machine grinding and cutter head. Therefore, it is possible to replace ordinary steel bars with glass fiber reinforcement in the shielding structure of the subway shield shaft, reducing manual cutting and removing the supporting piles within the shield range, greatly reducing the cutting loss of the shield cutter head, and improving the shielding efficiency. The efficiency of the tunnel and exit not only effectively improves the safety of subway construction, but also achieves a significant increase in economic benefits. In addition, the glass fiber reinforcement machine is simple and convenient, the construction process is simplified, and the operation is extremely convenient.
