Astro Pitch Construction

Basic Knowledge about Astro Pitch Construction

It can be summarized the astro pitch construction in general 5 stages: Infrastructure Works, iron and steel Works, wire mesh and file installation, synthetic grass carpet installation and finally lightining works. As it known every sport related field has its own standards. To get those standards, during the construction every step or stage have to be carried out carefully and adroitly. 

The main ones of these stages:

1. Infrastructure Works:

The choice of the ground where the artificial grass football pitch construction is planned is very important.  After the ground has been digged and flattened, it is compressed to zero code by vibrating cylinder. 30 cm deep foundation is digged around the field for ground beams and wooden molds are made in certain sizes.

On the long sides of the molds, two 12 mm diameter distribution bars at intervals of 30 cm., and 8 mm of stirrup pieces are added to these distribution. For the short sides, 6 pieces of 12 mm diameter distributing rods and 8 mm stirrup are used. Nut plates are fixed to iron reinforcement at intervals of 3 meters. For drainage, PVC pipes are used and laid into the beam. So, the water falling to the ground can be drain outside of the field. Then concreting the beam is formed.

2. Steel Construction Works:

4 m high pipes are mounted on the plates placed in the perimeter beam and 10 mm sheet metal plates are fixed on them. After this operation the trusses at certain sizes are mounted on sheet plates. 2 mm wall thickness pipes with a diameter of 32 mm are fixed horizontally on the trusses. In addition a hinged door and field masts are made. 

Note: Measurements of pipes are given as examples. They may may vary in each project. For example, at least 114'3mm main column pipes are used in snowy regions.

3. Wire Mesh and Net Installation:

Now it is the term of wire mesh. Synthetic football pitch must be sorrounded by 3 m height PVC coated wire mesh. Then, 5 mm steel rope is stretched and fixed with clamps. A net made of polyamide yarn in the range of 15×15 cm. is covered onto the pitch.

                                                                                   

4. Indoor Artificial Turf Application:

First, the felt has to be spread on the gravel flor and than it has to be wet. On this felt, the artificial grass carpet that has been selected by the owner of Project is laid on. 

The joint of artificial grass carpets are glued by a special adhesive. 

Now it’s time to make field markings according to the measurements. Finally the ground works of astro pitch are completed by sand and granule filling.

5. Indoor Astro Pitch Construction Lighting Installation:

Projectors lights are mounted on the stair-lined pipes placed on side of the pitch for lighting. The number of projector lights varies according to the size of the pitch.
