A COMPLEX FOR BUILDING A FLAGSTONE OF A CARRIAGEWAY OF A SECTIONAL TWO-LEVEL TUNNEL

摘要

The invention relates to building, particularly to constructing underground tunnels and underpasses. An engineering problem is improvement of the service performance of the complex due to modernization of a device of a track and facilitating its mounting inside the tunnel. The complex includes the device of the track located inside the tunnel, the engineering platforms with the set of equipment in the form of the load lifting mechanisms for the mounting and with the devices for dispensing concrete placed on the track, the mechanisms for shifting the sections of the casing of the flagstone of the carriageway. The device of the track is built on the lining of the tunnel at the both sides from the vertical axis of the tunnel over the level of the flagstone of the carriageway. Said device has the supporting bracket in the form of a space frame with a ground for fixing the track.
