Definitions

  • the present invention is part of the technical field of civil construction and more specifically of maritime works.
  • a structural drawer for maritime works comprises a plurality of segments of polymeric material that form horizontal segments that join together, creating the side wall of the drawer, and a base that is attached to the side wall and that can be of any type of material, preferably metallic or polymeric.
  • Maritime works include the construction of dikes in ports that are structures that allow reducing the action of waves on the ports in which they are installed.
  • vertical dikes are known as vertical, monolithic and waterproof wall structures.
  • this type of dykes are constructed with reinforced concrete drawers and have a gravitational behavior, that is, they base the stability of the drawer on their own weight.
  • the structural drawer for maritime works described is specially designed to be installed in vertical dikes that allows solving the problems described above. It is a prefabricated structural drawer, which is made up of a base and a plurality of segments, which generate a plurality of horizontal segments that join together to form a side wall of the drawer to which the base is attached.
  • an essential feature of the structural drawer very important feature of the present invention is that at least one side wall of the structural drawer comprises a plurality of segments that are joined together forming horizontal segments. That is, the total height of the structural drawer is achieved by joining, one above the other, a plurality of horizontal segments.
  • the lateral sides of the drawer are made up of horizontal segments, the joint joints between segments are simplified, substantially improving their structural behavior and construction.
  • the segments are of a height less than the height of the drawer because the total height of the drawer is obtained by joining several horizontal segments, the transport of said pieces is carried out more conveniently and economically.
  • the segments are made of fiber reinforced polymeric material and the base is made of a metallic material.
  • the base is metallic because it is used as a lost formwork and this has a lower cost than it is made of polymeric material such as the side wall.
  • the drawer additionally comprises a plurality of vertical columns that are attached to the segments and that can be used as stiffeners or as a formwork to fill them with reinforced concrete and that act by transmitting towards the base the loads generated by the placement of a concrete slab as a closure of the main space that is filled with ballast, if necessary.

  • the assembly procedure may include the following steps after the assembly steps of the drawer in the port (which are the ones described above):
  • the drawer is mounted in the port, which is the area closest to the end point where it is to be installed (which is at sea).
  • the elements that make up the drawer can be transported from the factory to the port independently. This makes it possible to speed up transport operations since you have to move parts much smaller and lighter than the complete set. This allows to facilitate the operations of displacement and to diminish the costs associated to these, in addition to reducing times.
  • the drawer assembly is carried out at the port and when it is already mounted it is thrown into the sea and taken to its final installation position.
  • the assembly could also be carried out in the factory in case users prefer it for some specific reason.
