The construction of the Gulf Crossing Bridge 8 The work that will last for a month now will be completed in 2 months: Underwater Stone Leveling System has been developed with the support of TÜBİTAK.
With the support of TÜBİTAK project, a system was developed to perform stone dump work on the deep sea floor of İzmit Bay Crossing Bridge. The system, which was expected to last eight months, was completed in two months.
Works on the Izmit Bay Crossing Suspension Bridge, which is the most important crossing point of ası Gebze-Orhangazi-Izmir Motorway Project işi, which will reduce the transportation of the highway between Istanbul-Izmir to 3,5 hours, continues. When the bridge is in service, the approximate 1,5 hour travel time will be reduced to 6 minutes. 550 meters of the middle span of thousand 2 meters, the length is 682 4 meters for the world XNUMX. for the suspension bridge which will be the title of the largest, deep sea bottom stone casting system was developed. TUBITAK TEYDEB by providing information about support system developed for the first time in Turkey Mechanical Engineer Tamer In fact, the field of transportation, he said the project is very worthwhile.
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. Real, lad With this system we developed, we completed our work in less than normal time. The work that will end in about eight months is over in two months. Without this project, we would do the work with the diver. It is very difficult to work under the sea 40 meter with a diver. Or the systems from abroad. This would increase the cost of 3-4 times. We prevented imports by developing it locally önlem.
