摘要

To provide a superior method than building a highway without reducing the traffic. Intended to build a highway flyover format that extends over the existing motorway The method: to build the foundation of the support portion, and built a supporting part in the foundation on, place the girder over the support section Installation of the support portion is performed during at least a portion of the technical equipment used in the work are arranged at the level of the upper working surface of the gantry type mobile facility; consists of steps for mounting the span structure Te. In self-propelled, preferably, for example, equipment of this construction is made of segments which are arranged side by side in a longitudinal direction; are placed in the assignment parcels within the existing motorway is mobile support of the equipment above; height clearance under the facility is sufficient to flow the traffic of the existing motorway; existing roads technical operation of at least a portion of the construction is mounted on the support section on the hoist mechanism of at least one said girder It is implemented to be able to flow traffic.
