MOVABLE FORMWORK APPARATUS FOR CONSTRUCTING TUNNEL CAVITY

摘要

The present invention relates to a movable formwork apparatus for constructing a tunnel cavity, in which a plurality of paired horizontal beams are installed in a width direction of a to-be-formed cavity; groups of two formwork plates are installed on a lower portion of the horizontal beams; a cart for moving the horizontal beams in a progress direction is formed on the bottom surface of the cavity; and a cylinder which varies an installation height of the formwork plates by means of a cylinder rod retractable to operate is installed on an upper surface of the cart. Accordingly, cavities having a wall can be continuously formed on an inner lower side of an excavated tunnel, an installation height of the formwork plates can be varied by vertically moving the horizontal beams by using the cylinder, thereby facilitating the formation of the wall and significantly reducing an operation time, and a through-hole is formed in the formwork plate and a home plate which blocks the through-hole or protrudes through the through-hole while moving forward and backward is formed in the formwork plate. Therefore, an operator is capable of forming a groove at a position of a desired cavity while moving the formwork apparatus.;COPYRIGHT KIPO 2020
