<p>The present invention relates to an incremental launching method for a concrete bridge, for constructing concrete girders constituting the bridge. The incremental launching method for the concrete bridge using transport carts and a winch, according to the present invention, is a method for installing the concrete girders between bridge supports, which are installed in a line with a specific distance therebetween, comprising the steps of: (a) arranging a plurality of the transport carts so as to be connected in a line, and on an upper panel preinstalled behind a bridge support on one side; (b) positioning the concrete girder on top of the transport carts; (c) installing and fixing the winch on top of a front bridge support on the other side where the concrete girder will be installed upon arrival, and advancing the concrete girder toward the bridge support on the other side by connecting a pulling wire of the winch to the frontmost transport cart and pulling the transport carts forward; and (d) releasing the pulling wire after advancing the concrete girder to the position of a bridge bearing of the bridge support on the other side, and then placing the concrete girder on top of the bridge bearing of the bridge support on the one side and the bridge bearing of the bridge support on the other side.</p> |
