Underwater structure connection with foundations - comprises textile bag inflated by compressed mortar filling

摘要

A structural unit is lowered onto a foundation element under water. The system includes one or more interposed connection devices filled with mortar that is pressed in, to provide bonding. The connection device (4) is a single celled or a multi cell textile bag (6) inflated by the mortar (5). In this are the structure (2) may have a collar (5) and/or recess, while the mortar-filled bag fills the space there and grips a head piece (9) of the foundation element (1). There is no need for hydraulic presses, horizontal forces are transferred, and wide tolerances are acceptable.
