ADVANCED TURF AND 3D REINFORCED SOIL

Direct relationship between grass stem height and grass root height
The higher the height of the grass, the higher the height of the grass root, but due to continuous lawn mowing and keeping the height of the grass short during root use, it will be severely shortened, and this reciprocal action will weaken the grass root in sandy soils. Therefore, because the texture of sandy soil does not have adhesive properties, it is easily removed due to pressure and severe shocks. Therefore, if reinforcing mesh is used in the soil, the roots inside the locked and pulled nets will be reduced to minimum.

Direct correlation of root length and different seasons of the year
Grass root length grows well in autumn and spring, but in summer and winter root growth is limited and severely reduced, so factors such as reinforcing nets to keep the roots in the soil and resistance to uprooting is very is necessary. By arming the grass soil, the following results are obtained:

  •  Increase the turf’s bearing capacity
  •  Increase the surface drainage capacity and prevent water retention on the surface
  •  Increase of oxygen available for respiration of roots in soil
  •  Improving the surface hardness of the grass to reduce the risk of injury to athletes
  •  Increase the ability to repair damaged parts of the grass by preserving its roots
Interaction of reinforcing networks and grass sandy soil texture mechanism
When the soil mass of the turf is affected, it sits under the weight of the soil and the weight of the maintenance machinery, including the tractor mower, sprayer, aerator, and the weight of the players. The pressure spreads into the bed soil. However, even when the applied stresses are completely compressive. Tensile strains may occur inside the soil.

If resistance is created against the applied tension, it prevents the soil from being compacted and the turf is plucked during the shot and tackle of the players. Soil compaction gradually causes water retention and due to water saturation during irrigation, the roots of the grass rot and the grass disappears. Also, due to compaction, the growth and development of the grass is difficult and stopped.

By adding three-dimensional reinforcing mesh to the soil and mixing it with mechanized equipment with a width of 2.2 meters, soil compaction is prevented and a significant part of the pressure applied by the reinforcing mesh is borne. Therefore, the soil is never saturated and oxygen is always available to the grass roots. On the other hand, the grass roots in the soil are locked inside the three-dimensional grids and this restriction prevents peeling during impact. Repeated digging in the grass causes low and high and after a short time the grass loses its uniformity.

Reinforced bed
Not reinforced bed
For robust reinforcement networks that have been used so far, two basic processes can be identified. Where sheets, strips, and rods are used, the load transfer depends on the frictional resistance developed at the point of contact of the soil with the resistant element. But for engineering networks, the load transfer will depend on the locking of the network members with soil particles.

The latter mechanism can be more efficient than surface friction and does not require relative motion between the soil and the resistant element to activate friction. Also, there is no limit created by the frictional properties of reinforcing materials in this method.
This constraint will be mainly proportional to the number and dimensions of pores (springs) in the network and the size and cross-sectional shape of the members of a network building.

This rightly proves that the locking principles apply to small members of the mixed soil network and can in fact be examined in two ways:

Initially, each member of the network is locked with a small group of soil particles to form a set, then these sets are locked together to form a sticky matrix. The recent unlock will be done by members of nearby networks.

Characteristics of reinforced soil and the presence of reinforcing nets in the turf bed enables sports such as Football and athletics, especially Javelin and Discus throwing, Equestrian, Hockey, Golf, car parking spaces

Scope of application in field sports:
In terms of project costs, implementation and maintenance costs, the amount and reliability of operation must be considered altogether. Most of the country's sports management budget of the past years of has been spent on frequent and often useless reforms of stadium lawns and restrictions.
Lack of visual appeal of destroyed grass in official competitions, especially on television, the poor quality of games and the complaints of players, coaches, and stadium spectators, and the injuries of athletes are also undeniable issues of sand based and traditional grass.
In the advanced turf system, the costs in terms of increasing the quality of operation, number of games, good quality of the field and freshness and freshness of the turf for players and spectators are much more economical than other turfs.
