TUNNELS ARE BEST BUILT WITH BFRP REBAR
The application of Basalt fiber reinforced polymer (BFRP) reinforcement in concrete structures, has encountering an increasing interest worldwide, for several applications in civil engineering.
The main advantages of the BFRP material are the lightweight, the high tensile strength and non-corrosive properties.
In underground structures mechanically excavated by means of tunnel boring machine (TBM), the lining is composed of precast elements, placed by the TBM during the excavation process and used as reaction elements during the advancing phase.
The application of BFRP reinforcement as a substitute of steel rebars in the precast segments of tunnel lining, could represent a suitable solution to the challenges of underground construction in terms of maintenance cost and durability.
Furthermore, the use of this non-corrosive reinforcement in tunnel segments allows reducing the concrete cover that is usually a weak point for this kind of structure, since it can crash during handling or due to TBM thrusts.
In addition, the BFRP reinforcement solution appears very interesting for the parts of the tunnel that have to be eventually removed (niches, vent channels, openings and stations), due to the easiness of demolition and disposal.BFRP Rebar is perfect for tunnels especially those close to water due to its non-corrosive nature, high specific strength, high specific stiffness, and lower specific weight relative to steel.
Lastly, BFRP Rebar should be used in tunnel construction because it is less expensive than steel and requires less maintenance.
