PROKON provided consultancy and supervision services for 1st Phase AŞTI-Çayyolu Metro Line Project.

Ankara Metro, 1st Phase AŞTI-Çayyolu Rail Transport System connects AŞTİ and Köy Hizmetleri Stations with a 5575 m long line and  Köy Hizmetleri and Ümitköy Stations with 3815 m long line. The double-track railway line was constructed together with 7 underground stations. The lane was constructed in different type of track ways; 0,140 km long At-Grade line, 0,070 km long Cut Line, 5,955 km long Cut&Cover Line, 1,945 km long Tunnel, 1,28 km long 7 station lines. The tunnels have been constructed in Cut&Cover and TBM Tunneling Methods.  The total closed area of 7 underground stations is 55.000 m².

Services within the scope of the project are listed below;

The points makes the project different from other ordinary designs are;

• Being composed of 7000 bar elements and 800 different load combinations,
• Mounting difficulties due to the extreme temperature differences in manufacture and erection sites,
• The use of HISTAR steel with very high strength.
• Thousands of loads, each calculated according to the 800 different load combinations,
• All nodes being “Slip Critical – Friction Grip”, Detailed Erection Engineering Service which may be the first in Turkey,
• Preparation of special video showing the practicability of erection works,
• Giving a reverse deflection to a truss having 108m opening (Mega Truss) and Preparation of the Shop Drawings accordingly, Preparation of Specific Engineering Calculations for the truss having four-story building height starting from pre-erection works to the Final Erection Stage,
• Extraordinary and specific solution of lifting and placement problems of an arch having 108 m opening (Facade Arch) which was complicated as a bridge itself,
• Considering the scenario of the cracking of the concrete over time which lies under the hangars,
• Transportation problems and occurring of difficult “brand” geometries due to the geometry of the structure.

Each Hangars, weighing approximately 1800 tons, (including the Erection Engineering) were performed by the COMOSYS software that was developed by PROYA Yazılım ve Ticaret A.Ş., a member of PROKON-EKON Group of Companies. ]]> https://www.prokon.com.tr/en/portfolio/turkish-wagon-industry-12-hall-preparing-hall-project/ Sat, 16 Jul 2022 21:38:26 +0000 https://prokon.sadeceinternet.com/2022/07/17/turkish-wagon-industry-12-hall-preparing-hall-project/
