In Ruppur, around 180 kilometres west of the capital Dhaka, the first national nuclear power plant is to ensure the power supply in Bangladesh from the end of 2023. In Ruppur, located around 180 kilometres west of the capital Dhaka, the first national nuclear power plant is to ensure the power supply in Bangladesh from 2023. The main reason for choosing Ruppur is its lie on the Padma River, which is to supply the cooling water for the planned power plant. Since the riverbank is an alluvial plain, a company had to be found that had extensive experience in drilling in sand and could provide the appropriate vibrators. With a total of three vibration units and over 2,600 tonnes of ASF anchor piles with a diameter of 64 cm and 90 mm thick, terra infrastructure played a major role in ensuring that the foundation could be built.
The vibrators used were an MÜLLER MS-50 H3, driven by an MS-A420 V power pack, and an MÜLLER MS-100 HHF vibrator, driven by an MS-700 V power pack, to drive the pipes with a length of 17 metres and a diameter of 630 and 1,020 millimetres. An even more powerful vibrator was needed to get the even larger pipes, up to 38 metres long and with a diameter of 1,420 millimetres, into the hard-to-penetrate subsoil.
Sand is one of the most difficult types of ground to work with. Therefore, only the MÜLLER MS 210 HHF and MS-240 HHF units, operated by MS-A 1050 V and MS-A 1150 V power packs, were considered suitable for the large pipes. These vibrators are among the most powerful in the industry. In addition to the initiation / commissioning of the vibrators on site, terra infrastructure provided technical advice during the entire project.
One important step in the project was the design for anchoring the terra ASF Micropiles. The technical office did a great job here and designed a special solution.
