4 Technical requirements
d. The technical requirements for the shrinkage pile should comply with GH 5, 4.2, the base height of type A cable tie is the minimum value for installing deck plates. In order to adapt to the beam arch and ridge of the middle plate, a margin should be reserved during processing. The height listed in Table 2 is only suitable for steel plates. When installed on a steel veneer with a wooden deck, it should be as shown in Figure 1, so that the base height is 15mm above the wooden deck.
4.3 Type A and R cable tie can be made according to the actual requirements of the order. The copper material is 11NT. 4.4 Type A and Type B cable tie with a nominal diameter of less than 503mm can be made of structural steel specified in G8162 or made of steel plates. The thickness of the pile listed in Table 2 and Table 3 is the minimum thickness when made of steel plates. When made of steel pipes, the specifications of the chain tie are in accordance with Table 7. Design requirements are shown in the appendix (reference part. 7

Appendix A
Design calculation of load and allowable stress of A and B type cable piles (Taike companion)
1.1 The load of the cable pile is 8-shaped and wound around the cable (wound on the support), and the load of the cable is the same as the load of the cable. See Figure 1 (in actual mooring, each pile only needs one mooring rope). A1.2 The design strength of the cable must be twice the diameter of the rope (one rope loop) (2F). The height of the end to be placed is from the bottom plate upwards: .2 times the nominal diameter. See A2.-A cable is wound around a thin pile with a letter color. At one end of the cable, a force P is hit. The force generated by the lack of appearance is close to 25. Therefore, under the condition of 1-1, the design force is 4. Figure A1
A2 Allowable stress
A2.1 High bending allowable stress is 86% of the torsion strength of the material, A2.2 Shear allowable stress is 6% of the ductility of the material: Additional instructions,
