Smooth-back tunnel lining method with suspended rebar fittings 'FK Anchor'

By installing the fittings when applying the waterproof sheet to the ceiling, the installation of anchor bolts is unnecessary!

The "FK Anchor" is a suspension rebar fitting that allows for the repeated reuse of the holding plate, enabling cost reduction. By changing the rebar suspension fittings from an anchor type to a pre-installation type during the construction of the back-smooth tunnel lining method, we can reduce the anchor hole drilling work immediately after demolding and prevent sheet damage caused by the cutting edge, achieving a revolutionary fitting and construction method. Since the rebar position is predetermined, the rebar rods always face the center, allowing for straight installation of the rebar. 【Features】 ■ Shortened work processes ■ Improved construction accuracy ■ Cost reduction through the reuse of components *For more details, please refer to the PDF document or feel free to contact us.
