Embodiment Construction

[0151] Next, a manufacturing apparatus of a curved panel according to the present invention will be described, and then, a method of manufacturing a curved panel using the apparatus will be described.

[0152] refer to Figures 1 to 3 , The curved panel manufacturing apparatus of the present invention includes: a fiber supply unit 1100 for supplying fibers; and a resin supply unit 1200 for supplying resin onto the fibers to form a fiber reinforcement 1090 . The curved panel manufacturing equipment also includes: a forming unit 1300, which shapes the fiber reinforcement 1090; a pulling unit 1400, which continuously pulls the formed fiber reinforcement along its transverse (or longitudinal) direction with a predetermined curvature a fiber reinforcement 1090; and a cutting unit (not shown) that cuts the fiber reinforcement 1090 produced continuously.

[0153] Such as figure 1 As shown in , the forming unit 1300 includes: a first forming part 1310, which primarily forms the fib...

Abstract

The present invention relates to a curved panel (3200) which is used to construct a tunnel in addition to an arch shaped underground or aboveground structure. The curved panel (3200) has a curved shape corresponding to the arch shape of the tunnel or the structure, thus increasing supporting force, thereby ensuring the structural stability, reducing the construction time, and enhancing the constructability and economic efficiency thereof. Furthermore, the present invention provides a method of manufacturing the curved panel (3200), an apparatus for manufacturing the curved panel (3200), a curved panel lining, and a curved panel construction method.

Description

technical field [0001] The present invention mainly relates to a curved panel, and more particularly to a curved panel, which is used for constructing tunnels in addition to underground or above-ground arch structures, the curved panel having The arc shape corresponding to the arch shape of the tunnel or arch structure, thus increasing the supporting force, thereby ensuring the stability of the structure, reducing the construction time, and improving the constructability and economic efficiency. Background technique [0002] Generally, in Korea, the construction of tunnels is indispensable when constructing expressways, national roads, railways, or city roads passing through mountainous areas because of geographical features. [0003] Most tunnels are formed through mountains or deep underground. Such tunnels are typically supported by stable bedrock, but tunnels may even be supported by unstable bedrock through the use of locking bolts, shotcrete, steel reinforcement or by...
