St. Avertin, June 25th 2014. CBE Group recently signed new contracts with a total volume of 256 moulds for tunnelling projects in Saudi Arabia, China, Mexico, India, Hong Kong, Iran and Singapore. These new projects underline once again CBE's commitment to be the world leading manufacturer of segment moulds and precast factories.
Amongst the new projects are four subway lines: Singapore, Jaipur, Wuhan and Riyadh Metro with tunnel diameters varying from 6000 mm for the Chinese Metro line in the city of Wuhan to 6000 mm for the Singaporean tube and 6350 mm for the Indian underground up to 9400 mm for the Riyadh subway. A total of 152 moulds will be supplied only to these four projects. Segments for Riyadh and Wuhan are to be produced by high performance carousel factories designed and made by CBE.
Additionally, CBE supplies six sets of segment moulds and a carousel precast plant to Consorcio Aldesem-Recsa-Proaconfor, the contractor for the construction of Emisor Poniente 2, a storm water drainage tunnel in Mexico. The 5.5km tunnel with an inner diameter of 7700 mm will have a capacity to handle 202m3/s and will run parallel to the existing drainage tunnel in the west of Mexico Valley, helping to reduce the risk of flooding in the Atizapán de Zaragoza, Tlalnepantla and Naucalpan municipalities.
Another water scheme, the Kani Sib Water Tunnel in Iran will be supplied by CBE with seven sets of moulds and a stationary precast plant. This project will be realised by Petro Omran in the Iranian province of Kurdistan and the concrete rings will have an impressive exterior diameter of 6000 mm, a thickness of 250 mm and a width of 1500 mm. Composition per concrete ring will be of three standard, two counter-key and one key-stone.
