Measures taken to ensure the safety of the Crimean bridge crossingAugust 5, 2017
This is the first case in Russia when a facility that has not yet been commissioned is provided with safety measures. Previously, such events were held only for fully finished structures. Information on the protection of the Crimean Bridge during the Gidroaviasalon held in Gelendzhik, an international exhibition, was provided by Vitaly Veresovich, who holds the position of deputy head of the Office of Federal Highways.
A four-lane road (first category) will pass through the Crimean bridge and a railway line (second category) will be laid. The total length of the axis of the highway exceeds nineteen kilometers, and the axis of the railway track is exactly nineteen kilometers.As indicated in the project documentation, the bridge will rely on almost six hundred (595) supports. The number of different types of piles to be driven for this exceeds seven thousand. The most difficult in engineering and technical terms will be the shipping span of the transport crossing. Its estimated length will be 227 meters. Next to the supports will build a special protective structure, the effectiveness of which was tested during the experiments. This will protect the bridge from the bulk of ships.
Were also conducted tests that determine the degree of stability of the bridge structure to the effects of wind flow. The calculations are based on meteorological characteristics describing the air currents characteristic of the construction zone. During the design, a model test of the strength of the bridge piers was carried out in an experimental ice pool.
The construction site of the transport crossing is fenced. The length of the fence exceeds seven thousand meters. Additionally, more than 130 security points are equipped, video surveillance is conducted. Entry and exit to the site, as well as the progress of construction work, are strictly controlled.All employees of companies involved in the work on the project, pre-check. From the water side, the security of the bridge is ensured by the border guard teams of the Federal Security Service and the Navy. Regular patrolling of the zone is carried out on boats, on a 24-hour duty there is a rescue tug, a base minesweeper and an anti-diversion boat.
After the introduction of the Crimean bridge into operation, the security of the zone will be carried out according to the classical scheme: control of warning and access, as well as video surveillance.
