Fiber reinforced composite panel for a protective wall to rock crushing and construction method of a protective wall to rock crushing using the panel

摘要

The fiber-reinforced composite panel for rock fracture barriers according to the present invention has a rectangular parallelepiped body having an empty space therein, and a bulkhead combines a plurality of partitions for dividing the entire space into a plurality of tunnels in the form of a square tube. In another embodiment, wing members are formed at both ends of one long side portion of the rectangular parallelepiped body to facilitate engagement with a neighboring unit panel, and the other long side of the rectangular parallelepiped body is provided. From a corner portion of the part to a predetermined area of the body surface is formed to step by about the thickness of each wing piece for engagement engagement with the wing piece of the neighboring unit panel, or in another embodiment the side of the long side of one side of the rectangular parallelepiped body V-channel grooves are formed for coupling with unit panels On the side of the other long side of the body is formed a projection for coupling with the V-channel groove of the neighboring unit panel.;According to the present invention, the rock fracture barrier panel is composed of a mixed material of glass fiber and unsaturated polyester, and the glass fiber to be mixed is also in the longitudinal direction (0 °), inclined direction (± 45 °), transverse direction (90) °), and because they are arranged so as to have directionality in a random direction, they are lightweight, yet have high strength and high durability. Therefore, there is an advantage in that the construction is convenient and the repetition rate is high.
