Underwater Stone Dull Leveling System was developed with the support of TUBITAK. With the TÜBİTAK-supported project, a system was developed to carry out the stone casting work on the deep sea floor of the İzmit Bay Crossing Bridge. With the developed system, the work, which was expected to take eight months, was completed in two months.
Work continues on the İzmit Bay Crossing Suspension Bridge, which is the most important crossing point of the Gebze-Orhangazi-İzmir Highway Project, which will reduce the road transportation between Istanbul and İzmir to 3,5 hours. When the bridge is put into service, the transportation time of approximately 1,5 hours will be reduced to 6 minutes. A stone casting system on the deep sea floor was developed for the suspension bridge, which will be the 550th largest in the world, as its middle span is 2 meters and its length is 682 meters. Providing information about the system developed for the first time in Turkey with the support of TÜBİTAK TEYDEB, Mechanical Engineer Tamer Gerçek stated that the project is very valuable in the field of transportation.
Today, a significant part of the engineering applications in the field of water (lake, river, river, etc.) and the sea bottom of the realization that the realization of the real, ve Bridge and underwater tube gate construction of the feet, lake, stream bed or the sea floor unprotected placement there is no question. Some special methods are used in the construction of the foundations of the bridge piers that sit on the lake, river or sea floor. One of these methods is the method of the caisson (which is constructed as reinforced concrete pylons and serves as a shoe foot). In the constructions where this method is used, the caissons must be placed on the smooth surface of the sea floor. In order to create a smooth surface at the sea floor, a flat and smooth bearing cover is constructed parallel to the surface of the sea, consisting of large and small (1-10 cm) stones, at the height of the area where the caisson floor will sit and at a certain height, called the caisson bed.
Stating that the stones are parallel to the sea surface is important for the soundness of the bridge, Ar We developed a system called ün ULE önemli as a result of our R & D studies. With this system, we fix the stones that are poured to make the caissons sit properly on the base. With the Stone Pour system, the stones are not smooth and then these stones are leveled with the help of a knife under the 40 meter of the sea. On the leveling stones (gravels), the caissons sit. If the leveling surface is not smooth, there will be a problem of steepness in the caisson. Tes
ulei the very small size of voicing used in the Marmaray In fact, he said that a system of this size used for the first time in Turkey Izmit Bay Crossing Suspension Bridge. Truth, “With this system we developed, we completed our work in less than normal. The work, which will be completed in about eight months, is completed in two months. Without this project, we would do things with the diver. It is very difficult to work with the diver 40 meters under the sea. Or we would do it with systems from abroad. This would increase the cost 3-4 times. We also prevented imports by developing this locally. ”
