EXPERIENCE IN RESTORING DESTROYED AUTOMOBILE ARTIFICIAL STRUCTURES

Abstract

Purpose. The issue of resuming automobile traffic is an important task for the resumption of logistical state and local movements. The purpose of the work is to study and implement the experience of restoring transport infrastructure and construction of fortifications, its distribution, and the wide implementation of lessons learned in the training process of units of the State Special Service of Transport and other bridge construction specialists. The experience of using reserve beams under railway load for a road bridge is shown on the example of the restoration of automobile traffic across the Irpin River for passenger cars without load capacity restrictions. An example of restoration of man-made structures on the detour next to the bridge is given. Methodology. The issue of resuming automobile traffic is an important task for the resumption of logistical state and local movements. Examples of restoration of artificial structures are given. It also shows the use of modern technologies, mechanisms, and methods of restoring structures on the bypass or on the old axis of the bridge. Findings. The main elements of the bridge over the Irpin river located on the public highway of state importance Ib technical category M-06 Kyiv-Chop (to the city of Budapest via the cities of Lviv, Mukacheve, Uzhhorod) were destroyed by mechanical damage as a result of hostilities in Ukraine. The characteristics of the destruction do not contribute to the restoration of the artificial structure on the existing axis of the structure. The restoration of the bridge was carried out on a short detour – 50 m downstream of the Irpin River. Originality. Today, the need to restore artificial structures arises in connection with their destruction during the war and after disasters of a natural, man-made, and military nature. There is an urgent need to study and implement the experience of restoring the transport infrastructure and construction of fortifications, its distribution among the personnel, the wide implementation of the lessons learned in the training process of the units of the State Special Transport Service. Practical value. The practical result of the use of reserve span structures of small and medium-sized railway bridges was obtained, which confirms the universal possibility of using the structures of the inventory bridge property, not only for conducting restoration works on the railway, but also for the restoration and construction of a temporary road bridge.
