1915 Canakkale Bridge construction used push-sliding technique.

In Europe in the 1960s, the push-streaked into use at the beginning of Turkey also often a preferred method of bridge construction. With push-sliding method, both time loss is prevented and on-site production is made.

Turkey’s vision of 1915 Bridge project in ceaseless push-riding technique was used in the study. The push and slide method (Incremental Launch MethodILM), which has many applications around the world, is a bridge construction method that has started to be used in our country. With this method, the bridge deck is poured and pushed on one side of the valley by using a single mold. The production, which started with the construction of the feet first, continues with the establishment of the fixed mold area. Then, the deck is poured one after another and pushed out of the mold. By using sliding supports on the bridge legs, friction forces during pushing are reduced. The deck openings generally vary between 40 m and 60 m, and continuous decks with lengths of up to 700 m – 800 m are formed. The shortening of the construction time, the decrease in the amount of materials with the hyperstatic continuous deck, the decrease in the number of supports and the number of expansion joints are the biggest economic benefits of this method.

Earthquake acceleration is reduced

In high-legged bridge applications using push and slide method, it is aimed to increase the effective period by using more flexible feet in the earthquake design, thereby reducing the earthquake acceleration to the feet. In the bridge design, the use of viscous fluid dampers to limit displacement values ​​and reduce the earthquake effects that will occur on flexible feet provides a great advantage in terms of both design and amount of materials.

The decks will consist of 42 pieces

The decks, which are 17 meters wide and 30 meters long, will consist of a total of 42 pieces. With the ongoing works at the bridge construction site, it was learned that the decks will be brought to the area where they will be placed by push and slide method in the coming days.

March 18 will symbolize Çanakkale Naval Victory

The bridge, which is stated to have the title of the biggest suspension bridge in the world, symbolizes Çanakkale Sea Victory on March 18 with a height of 318 meters. The feet of the 1915 Çanakkale Bridge, the foundation of which was laid by President Recep Tayyip Erdoğan on March 18, 2017 and under construction between Şekerkaya and Gallipoli in the district of Lapseki in Çanakkale, was completed with a conference attended by President Recep Tayyip Erdogan on Saturday, May 16. The foot height of the bridge, which was composed of 32 blocks, reached 318 meters.

The bridge will include the depiction of Seyit Onbaşı.

The bridge representing the March 18 Çanakkale Naval Victory will consist of 32 blocks. At the far end of the towers, there will be a depiction of the cannonball that the unforgettable hero of the Dardanelles Wars, Seyit Onbaşı dropped into the barrel. The middle span of the 1915 Çanakkale Bridge representing the 100th anniversary of the founding of the Republic is planned to be 2023 meters. This opening has the feature of being the suspension bridge with the highest inter-tower span in the world. After the bridge is opened to service, the transportation distance between the two sides will decrease to 6 minutes. It is envisaged that the bridge will also provide serious benefits to the region and that investor demand will increase especially to Lapseki.

To be completed on March 18, 2022

1 suspension bridge, 2 approach viaducts, 4 reinforced concrete viaducts, 6 underpass bridges, 38 overpass bridges, 5 bridges, 43 underpasses, 115 various sizes culverts, 12 junctions, 4 highway service facilities, 2 maintenance operation centers, 6 fare collection Station will be built and the 1915 Çanakkale Bosphorus Bridge will be completed and opened to service on March 18, 2022. – CANAKKALE.
