Tryggve Larssen (civil engineer)

from Wikipedia, the free encyclopedia

Tryggve Larssen (born November 27, 1870 in Porsgrund , Norway , † January 9, 1928 in Bremen ) was a German civil engineer of Norwegian origin.

Life

He was the state master builder (building officer) of the Hanseatic City of Bremen and is known as the inventor of the steel sheet pile wall (around 1902), for which he applied for a patent in 1904. The Larssen profile (with U-shape), later named after him, which was sold and further developed by the Hoesch company, was initially riveted. Larssen profiles are still in use today. The first such sheet pile wall was rammed in the Hohentorshafen in Bremen in 1902 and is still standing today.
