रियाद मेट्रो रियाद, सऊदी अरब में निर्माणाधीन एक विशाल शहरी पारगमन प्रणाली परियोजना है। इस परियोजना में 176 किमी की कुल रेल लंबाई के लिए 6 पारगमन लाइनों के साथ निर्मित 85 स्टेशन होंगे। उम्मीद है कि 2018 में अपने उद्घाटन के समय यह प्रणाली प्रतिदिन कम से कम 1 मिलियन यात्रियों को सेवा प्रदान करेगी।
For this large infrastructure project, Dextra Middle East has been involved on various stations and packages.
उत्खनन कार्य
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.
बेड़ा और ऊर्ध्वाधर कनेक्शन
बार्टेक रीबार कप्लर्स 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 यूनिटेक 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.
