Definitions

  • the invention is related to the foundation piles which may be used in place of bored piles under land structures, especially related to the foundation piles which are connected with the structure on the sea from one end and driven into the seafloor at a certain depth from the other end for securely bearing the structures founded on the sea such as piers, bridges, platforms, etc.
  • the invention is particularly related to prestressed reinforced concrete pipe pile and a production method for said pipe pile.
  • the structures such as water pier, bridge, dock, platform etc. are established on the waters of sea, lake, ocean etc.
  • Foundation piles are used to carry these structures.
  • the foundation piles are driven into the sea floor at a certain depth from one end and connected with structures on the water surface, thereby having the function for bearing those structures.
  • the foundation piles used to bear the structures are generally made of steel.
  • Steel piles are driven into the sea ground at a certain depth and a part of the steel pile remains in the ground. The remaining part of the steel piles on the ground is connected to the platform pertaining to the structure by extending in the water.
  • Composite (steel + concrete) foundation piles can also be used to reduce costs in the present technique.
  • the outer part of the remaining part in the salt water is made of steel material and the inner part is manufactured with concrete reinforcement of high strength whereby it is tried to extend the life of the piles. In this way, it is tried to ensure that the concrete and steel reinforcement inside performs the bearing function even though the outer part corrodes in the process of time.
  • these products also bring about risks due to corrosion and material melting. It is not often preferred due to its difficulty of production process for having a composite structure compared to the pile completely made of steel.
  • the related patent discloses methods and test apparatus for testing tensioning members in a prestressed concrete conduits such as for example water pipes and water reservoir vessels.
  • This device comprises a magnetic flux production means and a detector which is disposed proximal to a surface of the conduit in a common plane with the magnetic flow production means perpendicular to an axis of the conduit.
  • the device operates in a series of low frequency signals or a pulse, such as for example in the range of 20 to 300 hertz.
  • the output of the inspection device includes the signal and distance graph showing the results of a test of one conduit at one or more frequencies.
  • the characteristic of the output phase is plotted according to the distance, including the phase or symbols of the phase-in or quadrature components of the signal received according to the driver signal.
  • Another patent is Turkish Patent Publication No. TR2016/15468.
  • This patent is related to a seismic isolation system, which is located on the deep seabeds, comprises a concrete caisson, a caisson lower plate where said concrete caisson is seated and lies on an aggregate bed, a touch surface (friction surface) created under said lower plate, is fixed on said friction surface and caisson lower plate, and comprises steel piles which are anchored into the seafloor, for the purposes of applying to the piers of the bridges on the suspension bridges the towers of which are located on coastal areas.
  • the Turkish Patent Publication No. TR2009/09745 is related to the components of coating systems used for protecting pier piles and pipelines against corrosion.
  • the invention includes a coating method used for protecting and rehabilitating the parts of the steel and concrete pier piles, which are in the wave splash zone (at a distance of +1 and -1 meter from the water level), and the pipelines against the corrosion.
  • the main object of the invention is to eliminate the existing disadvantages by developing a prestressed reinforced concrete pipe pile and a production method for said pipe pile.
  • Another object of the invention is to significantly increase the strength of the pile by prestressing the steel bars in the tubular foundation pile made of high strength concrete.
  • Another object of the invention is to provide a long-lasting pile structure by preventing corrosion and material dissolution on the pile by means of the fact that the parts of the foundation pile which are immersed in the sea floor and remain in the salt water are completely made of concrete.
  • the safety of the structure and people on the sea is also increased as corrosion and material melting etc. do not occur on the outer surface of the concrete pile by providing that the steel bars forming the skeletal structure of the concrete pipe pile and metal wires wrapped around steel bars remains within concrete and thereby there is no direct contact with salt water.
  • Another object of the invention is to develop quite a low-cost product and a production method for this product as compared to steel piles as reinforced concrete is used instead of steel.
  • Another object of the invention is to leave the excess water in the concrete due to the effect of high centrifugation during production and thus to achieve high impermeability and high strength values.
  • Figure 1 is a perspective view of the steel bars and wires forming the metal carcass of the reinforced concrete pipe pile along with the prestressing flange and the sealing cap.
  • Figure 2 is a representative perspective view of the steel bars having a prestressing flange at the end thereof and being between both molds in the case before lower mold and upper mold are not closed.
  • Figure 3a is a perspective view of the final prestressed reinforced concrete pipe pile along with the prestressing flange and sealing cap.
  • Figure 3b is a perspective view of the final prestressed reinforced concrete pipe pile after the sealing cap has been removed.
  • Figure 4 is a representative process flow diagram of the production method pertaining to the prestressed reinforced concrete pipe pile according to the invention.
  • Figure 5a is a side view of the prestressing flange.
  • Figure 5b is a perspective view of the prestressing flange.
  • G Closing an upper mold part on the lower mold and bolting the upper and lower mold parts together into each other.
  • the invention relates to a prestressed reinforced concrete pipe pile (1 ) and a production method for said pipe pile.
  • Figure 1 shows a representative perspective view of steel bars (2.1 ) and steel wires (2.1 ) wrapped around the steel bars (2.1 ) at regular intervals, which form the reinforcing carcass (2) of the prestressed reinforced concrete pipe pile (1 ).
  • Figure 2 shows a representative perspective view of the steel bars (2.1 ) which are between the two molds in the case before closing the lower mold (8) and the upper mold (9) and which the prestressing flange (4) is located at both ends thereof.
  • the button headed steel bar ends are fixed to the steel bar connecting slots (4.1 ) of the prestressing flanges (4) which are located at both ends of the reinforcing carcass (2) and preferably have ring form ( Figure 5a, Figure 5b).
  • the sealing cap (5) is temporarily mounted to the outer-side of the prestressing flange (4) for sealing purposes. The sealing cap (5) is removed after the final product is obtained.
  • the prestressing of the steel bars (2.1 ) is carried out by the torque force exerted by a tension rod (6) connected to the prestressing flange (4) connected to the button headed steel bar ends.
  • the force required for the prestressing is provided by the torque force applied by a torque machine to the tension rod (6) which passes through the mold cover (10) and the locking nut (7).
