Middle location in Urumia Lake Highway

این پروژه به علت بستر لجنی آن که ضخامتی بین 15 تا 25 متر داشته و ظرفیت باربری آن عملا ناچیز است و هر نوع خاکریز و سازه در آن فرو میرود یکی از مشکل ترین پروژه های آبی کشور محسوب میشود .

Middle location in Urumia Lake Highway

One of the most important challenging project was Highway of middle location in Urumia Lake with very soft sludge at its bed.

- This highway has 14.15 Km. length, and about 40 m crest width with long slopes covered with Armour layer having technical specification of bermed break water in sub-horizontal shape for berms.
- Middle part of the highway was built a large bridge of 1300 m length with 18 piers constructed. Middle bay of bridge has a span of 100 m arch truss of stayed bridge with several vertical and inclined elements for supporting large suspended deck – Main section of bridge is trapezoidal steel caisson structures.
- Construction of each pair is of group of long piles with strengthening of inclined piles. Each group of piles (up to 86 m depth), because of softness of lake deposit from wich 15 to 25 m sludge was laied down. Cap piles of each pier of a sort of precast concrete caisson.
- Construction of both side bermed break-water due to softness of its bed was very challenging engineering problem.

This project is key challenging project in IRAN wich is designed by Ab-Niru consultant engineers.
