Concrete header beams for free-standing sheet pile retaining walls etc. is manufactured in one piece of long length by sliding shutter method

摘要

The header beams (1) connect individual elements of retaining walls for ground areas of different heights. Each concrete beam is constructed in one piece, in a sliding shutter method, using shuttering elements moving in longitudinal direction of the beam, in a single casting stage. A construction machine with sliding shutter elements moves along the wall elements (2), which have been coated with a cleaner layer (4). Each beam has a drainage channel, and continuous longitudinal reinforcement (6,7), which overlaps with the reinforcements of the wall elements, and also acts as earth connection
