More than a hundred years ago, the seawall in Westerland on the island of Sylt was built to protect the town's exposed houses against tidal waves from the sea. With masonry breaking off in places and damage to some of the joints, the 500 meter long beach front wall is currently being reinforced section by section.
Bauer constructs cut-off wall for hydroelectric power plant in Nepal
The Arun River in Nepal flows from Tibet through the Himalayas into China. Of all Nepalese river basins, it has the largest area covered in snow and ice. A new hydroelectric power plant is currently being constructed on this river, and it is expected to produce up to 900 MW of electricity. BAUER Engineering India Pvt. Ltd. was tasked by the Indian company Jaiprakash Associates Limited with the construction of a cut-off wall as part of the project Arun III HEP. The goal is to achieve a seal and reduce seepage water below the upstream cofferdam and in the left and right abutments.
The scope of service provided by Bauer includes the execution of 3,500 running meters of drilling and injection work on the cofferdam. In the granular construction soil, composed of sand, gravel, rubble and boulders, the pore injections are executed by means of tube-à-manchette and annular grouting.
