A good football field football field that is able to
satisfy the sight of a football crowd. Football
field should look green, it means consists of a terawatt and fresh grass. In
Indonesia there are many football clubs who have strong players, but not as
tough as the players from Europe. Indonesia
football player movement looks pretty slow. When
it rains then they move more slowly and more controlled tidaak banyaak caused
the football field became slippery. The
direction reflections bolapun be difficult to guess if there are puddles
banyaak. The
grass is green to green is not visible, it looks muddy. So
the game of football that had been a dry football field becomes like playing football
in the middle of rice fields. Many
uapay done by the builder sepaak football field. I have a
different solution in building a soccer field. The
technology was so simple, except perhaps the grass must be imported from
overseas, namely China. Simple
technology, the intention is to use local aggregate product. The
amount of time playing football is a 2 x 2 x 45 minutes plus 15 minutes if
there is an extension of time to play in the event series. So the total games
for 120 minutes or 2 hours. Estimated
rainfall occurs is 2 hours before the game starts until the game is completed. In
general, if there is heavy rain, the game was postponed, unless rain falls
during play, but I provide the best solution. Estimated to be very
heavy rain for 4 hours. So the water level is
expected to occur for 4 hours. Water entering
the field must be absorbed quickly. Technology
to absorb water has been done in Europe including the United States as the
Football game. They
used a special plastic coating material under layers of sand and grass with a
certain depth.
But
I give different solutions. I
use carpet because the carpet is cheaper, more durable, and have pores are
closer together so as to hold the sand on it. This
way: football field should be dug as deep as 1 meter to 1.5 meter in each flat
surface of the same field. The
results of excavation must be removed. The
first layer should be replaced with stone and gravel aggregates did not pass
the filter no.20mm. so all the
mud and sand must pass a 20mm sieve number. not
pass the filter aggregate layer 20mmm, well-shaped stone is large or small
should be so arranged as thick as 60 cm, the goal to provide a sufficient
number of pores when rain occurs, the water directly into the pores between the
stones. Then
on the rock and gravel aggregate is loaded a fairly thick carpet. Carpet
prices are not too expensive if it must cover all the football field. Carpet
is installed over a sand aggregate must pass sieve no.200, which means it does
not contain the mud. To
eliminate the mud there are two ways ie by filtering with sieve no.200, did not
take long to perform the activity. The
second way is to require a lot of water to remove mud. Aggregate
passes No.200 sieve and then spread over the carpet. Left
with a thickness of about 5cm or 10cm upper layer of grass to the media. Last
layer is a layer of stone-free soil, so the field becomes tender. Grass can be used on it. So
the field does not need another ditch, the ditch which would be harmful to the
feet of the players or spectators, especially when things happen that are not
desirable. Water
easily absorbed, the game becomes more easy on the eyes. Happy Playing.
