Second lock, Trier
Necessitated by capacity limitations
As part of a programme of works to eliminate capacity bottlenecks on the Mosel river, a second lock was built adjacent to the existing lock at the city of Trier. The monolithic lock construction has a useable chamber length of 210 m and a chamber width of 12.5 m. Depending on river water levels, it accommodates ship lifts/drops of up to 7.25 m.
Inros Lackner’s planning and design responsibilities covered, among other items, the lock structure (masonry and steelwork), the upper and lower approaches, the anti-scour treatment, the lock excavation, the associated infrastructure, and foundation engineering. A berth with a total length of 225 m was constructed in both the upper and the lower approaches, with sheet piling used in the upper approach and a bored pile wall with facing formwork constructed in the lower approach. During the construction phase, year-round operation of the existing lock chamber had to be ensured.
