A Putzmeister BSA 1004 D concrete pump has been used to lay the foundations for a lighthouse project in Oman.
New lighthouses have been built on Masirah island located off the east coast and Ras Madrakah further south. Assisted by Taylor Woodrow Oman and the Omani Putzmeister dealer IHE (International Heavy Equipment), the construction company Al Sarooj used a helicopter and a BSA 1004 D concrete pump manufactured in India to construct the foundations of the lighthouse and minimise the impact on the environment.
While in Ras Madrakah the foundations were also laid using a helicopter, on Massirah the 65m³ of concrete required was transported through a pipeline more than 110m long from a temporary preparation site up the hill to the main construction site.
The pipelines were mostly secured using ropes and chains, but had to be secured with stone-filled sacks in places. A GVHM 2/2 gate valve integrated in the pipeline prevented the concrete from flowing back towards the concrete pump during breaks in pumping.
Two mobile concrete mixers were used to produce concrete with a maximum particle size of 20 mm. In order to monitor the concrete quality and prevent blockages, workers took samples from every batch that was mixed and continuously monitored concrete production.
To overcome the height of 110m, IHE converted the drive end of the BSA 1004 D before pumping started so that the pump would produce a maximum concrete pressure exceeding 100 bar.
All of the concreting work was performed during the night due to the high temperatures.
