pooljäreltõstetud

Pooljäreltõstetud refers to a construction technique used in certain types of concrete structures, particularly bridges and buildings. This method involves casting structural elements, such as beams or slabs, in place and then lifting them into their final position using hydraulic jacks. The term "pooljäreltõstetud" translates roughly to "half post-tensioned" or "partially lifted," indicating that the lifting process is a key part of the overall construction. Unlike fully pre-cast elements that are manufactured off-site and then assembled, or cast-in-place elements that are built entirely in their final location, pooljäreltõstetud elements are cast and then moved. This technique can offer advantages in terms of speed of construction, reduced need for extensive temporary support structures, and the ability to construct in challenging environments where traditional methods might be difficult. The process typically involves casting the concrete segment on temporary supports or a launching gantry, then using hydraulic jacks to push or lift the segment into its designated position. Post-tensioning might be applied after the segments are in place to achieve the required structural integrity. This method is often employed in bridge construction, allowing for the extension of spans over existing infrastructure or waterways without significant disruption.
