Метро Эр-Рияда — это масштабный проект городской транспортной системы, строящийся в Эр-Рияде, Саудовская Аравия. Проект будет включать 85 станций, построенных на 6 транспортных линиях, общая длина железных дорог составит 176 км. Ожидается, что на момент открытия в 2018 году система будет обслуживать не менее 1 миллиона пассажиров ежедневно.
For this large infrastructure project, Dextra Middle East has been involved on various stations and packages.
Земляные работы
Before proceeding with general construction works, during early excavation phase, it is required to anchor retaining walls back into the stable ground in order to prevent any wall displacement. This will allow to keep excavating in a safe environment.
For that purpose, Dextra supplied steel ground anchors installed through retaining wall. Each system is based on a high-tensile fully threaded bar, coming with nut and plate, and grouted to provide bonding with the soil.
Плот и вертикальные соединения
Арматурные муфты Bartec were supplied for the works in the stations. Couplers were used for slabs, column and wall connections. A typicall application on this project is to cast rebar couplers in the concrete with reinforcement, and then proceed with second phase bar connection at a later stage.
Unitec bolted couplers can have also been use on various parts of the project. Typically Юнитек is used when overlap is planned but lapping length appear to be too short to perform a safe splice. In that case Unitec provides a convenient and full performance connection.
