DETAILED DESCRIPTION OF THE INVENTION

[0056] In this detailed description, preferred alternatives of multiple friction articulated pile embodiment of the invention are described only for a better understanding of the subject and without any limiting effect.

[0057] The invention comprises a bearing element (100) comprising at least two parts and preferably at least one twisted wire duct (101) positioned at any point on the bearing element (100), wherein the twisted wire duct (101) is long enough to connect the bearing elements (100) passing through the duct in the amount to meet the need. The diameter of the twisted wire duct (101) must be at least three to five times the diameter of the twisted wire. This gap allows movement in the lateral direction. In order to prevent contact between the twisted wire and the bearing element, the twisted wire is passed through a hose and this structure is passed through the twisted wire duct. The bearing element can be solid or perforated. It is not necessary for this element to be concrete; different materials such as wood, steel, composite, stone-filled cage, etc. can also be used. The important feature is the presence of a hole where the anchor will pass through the block and if the material forming the block consists of grains, it must be permanently bundled.

[0058] The invention comprises a geomembrane (rubber, cut waste car tire, geofoam, etc.) of the thickness required by the project placed between two bearing elements (100). However, it is not necessary to have a geomembrane for horizontal displacement. The soft material will be useful in preventing vibrations in the vertical and horizontal directions.

[0059] The invention is held together by a sufficient amount of bearing elements (100) and twisted wire (120) which is passed through the twisted wire duct (101) located on the flexible plates (110) placed between said bearing elements (100). The twisted wire (120) can be adjusted by loosening and tightening from its top and it is connected by a twisted wire tightening and loosening apparatus system. This tightening and loosening apparatus can be dywidag, anchor 4-cone or gripper. The lower part of the twisted wire (120) includes the twisted wire fastening system (140). Here, terminal or gijon systems, etc. with headless setscrew can also be used.

[0060] Among the figures used to make the invention more understandable, FIG. 1 and FIG. 2 illustrate the pile system used in the prior art and the disadvantage thereof.

[0061] FIG. 2 shows the movement of the monolithic pile under the lateral force F from the point X0 to the X1, and the fracture or crack 11 creation status of the monolithic pile under the force F. These pile systems built on the foundations of structures such as buildings, bridges, etc. break when the ground is exposed to earthquakes or other natural factors. The product and system of the invention developed to prevent this are explained in more detail below with the figures.

[0062] FIG. 5 illustrates a representative connection of the rigidity-adjustable pile system with large displacement, wherein the system is connected together with the bearing element 100 and the flexible plates 110 positioned between said bearing element 100 and the twisted wire 120 used to keep the system together by passing through the bearing elements 100 and the flexible plates 110 and twisted wire tightening and loosening apparatus 130, which is connected to said twisted wire 120 preferably on the upper section, and the twisted wire fastening apparatus 140, which is connected preferably from the bottom.

[0063] FIG. 6 is a cross-sectional view of the representative connection of FIG. 5.

[0064] FIGS. 7 and 8 show sections A and B, respectively. Section A shows the tightening and loosening section and section B shows the fastening section. However, the connections shown in these two figures are representative and are included to make the invention more understandable, and have no limiting effect.

[0065] FIG. 9 shows a representative operating mode of the multiple friction pile system.

[0066] FIG. 10 illustrates how the multiple friction pile system operates in the event of axial shift, and the individual effect of the lateral force F in which the bearing blocks 100 are affected from any direction on the bearing blocks 100 is shown. Here, the bearing elements 100 shifting due to the force F are movable since they are designed as independent units. When the twisted wire 120 is overloaded inside the multiple friction articulated pile system, it can be loosened with the help of the twisted wire tightening and loosening apparatus 130 located on the upper part and the load on the twisted wire 120 can be reduced. Similarly, in cases where it is desired to tighten the twisted wire 120, the desired tension is obtained by tightening the tightening and loosening apparatus 130. The possibility of fracture and/or cracking of the column is eliminated by the multiple friction articulated pile system placed under the structure this way.

[0067] The pile system formed also withstands the torsional forces with the frictional force in the joint planes. Exceeding this strength will not cause the pile to twist, but this block will only rotate. This feature will minimize the torsional problems especially in pile groups.

[0068] In the present invention, it is also possible to use the pile for drainage in the horizontal and vertical directions by the holes formed in the horizontal and vertical directions of the bearing elements 100. These holes are separate from the twisted wire hole. These holes on the bearing elements 100 provide the discharge of water in the pile well. When necessary, cement slurry, lime slurry, chemical, bentonite, etc. mixtures can also be fed to the ground with the help of these ducts. This has created a new combined soil improvement method.

[0069] Additionally, piles can be created by using one or more geogrids 103 instead of geomembranes in the articulations and the geogrids 103 can be connected to each other from the upper region and the lower region of the articulated pile. The frames thus formed can be used in geotechnical applications such as forming deep foundations, retaining structures, approach embankments, platforms, etc. Geogrids 103 are anchored in the upper section of the pile by squeezing between the concrete blocks and provide additional bending rigidity during lateral loading after being placed on the pile surface along the pile, and then being anchored between the concrete blocks at the other end of the pile. When the same operation is performed on the other axis, an articulated pile is formed in which the bending strength is increased in both directions.
