<p>In the present invention, provided is an injection apparatus of amorphous fibers, which prevents amorphous fibers from being tangled and is reformed, so that a proper length of amorphous fibers is selected and a proper amount of amorphous fibers is measured, being injected, comprising a storage hopper used for storing amorphous fiber which is injected into concrete mixtures and is accordingly used for increasing strength of concrete mixture; at least one porous net which is installed in the storage hopper and has a plurality holes to enable amorphous fibers whose size is smaller than the hole to fall; a vibration generating part which is installed in the storage hopper and assigns vibration, so that the amorphous fiber can pass the porous net; and an opening and closing part which is installed in the storage hopper and is opened and closed by the weight of the amorphous fiber through the porous net.</p> |
