  • Steel reinforcement bar TW8 18.8 m (61.6 ft) / 7.4 kg (16.4 lb) to make:

    • Reinforcement TW8 C-shape, base rod length 1000 mm (39.37 in) Ø 8 mm (12 pcs)
    • Reinforcement TW8 straight, base rod length 850 mm (33.46 in) Ø 8 mm (8 pcs)
  • Reinforcement TW8 C-shape, base rod length 1000 mm (39.37 in) Ø 8 mm (12 pcs)
  • Wood for building the mold
Wear protective eyewear, gloves, and a safety helmet.

To prepare the foundations, use:

  • Foundation bolt (7 pcs)
  • Nut (12 pcs)
  • Nut with plate (3 pcs)
  • Metal plate (1 pc)
  • Orientation template (1 pc)

Prepare the installation location for 1 mast concrete foundation and 3 guy wire concrete foundations.

  1. Make 4 cast molds from wooden boards for the concrete foundations.

    The dimensions of the concrete foundations in the reference calculation must be:

    • Height 500 mm (19.69 in)
    • Width 950 mm (37.40 in)
    • Length 950 mm (37.40 in)
  2. For each foundation, dig a hole with sides approximately 2 m × 2 m (6 ft 7 in × 6 ft 7 in) and depth 1 m (3 ft 3 in).
    In a square foundation, the sides of the square must be in the North/South/East/West direction.
  3. Spread a layer of gravel and level the gravel with a wooden board.

    The distance from the surface of the gravel to the ground level must be 500 mm (20 in).

    Backfill
    3
    Cable conduit (2 pcs)
    4
    Drainage (optional)
    5
    Compacted gravel
  4. Compact the gravel with a plane compactor or similar device.
  5. Consider the individual site requirements and use drainage pipes if the ground on the site is wet.
  6. For each foundation, use:
    • Reinforcement TW8 to create 8 straight pieces, base rod length 850 mm (33.46 in)
    • Reinforcement TW10 to create 18 straight pieces, base rod length 850 mm (33.46 in)
    • Reinforcement TW8 to create 12 pieces of C shapes
    • Reinforcement TW10 to create 2 lift parts
  7. Build the reinforcement structure in the cast mold from TW8 and TW10 according to the given measurements and layout instructions.
    • Place stands under the reinforcement structure.
    • To hold the structure, use steel wire.
    The following figure does not show the arrangement and number of foundation bolts in DKP206 and DKP210. There are 4 foundation bolts.
    1
    TW10 straight (18 pcs); if no lift parts are used (20 pcs)
    2
    TW10 lift part (2 pcs), optional
    3
    TW8 straight (8 pcs)
    4
    TW10 straight
    5
    TW10 straight
    6
    TW8 C-shape (12 pcs)
    7
    TW10 straight
    On the top layer of the reinforcements, place the lift parts under the straight parts.
  8. For the guy wire foundations, fix the foundation bolts to plates with nuts and place 1 foundation bolt to each foundation and tie the bolt with wire to the steel reinforcement bars.

    Leave 40 mm (1.57 in) of the foundation bolt above the concrete in the finalized block.
