Four considerations for building artificial turf

In recent years, with the continuous renovation of artificial turf construction technology and the development of fiber materials and filling materials, many disadvantages of artificial turf such as high surface hardness and poor buffering performance have been gradually improved. Of course, these are based on the correct selection of turf materials and Only by ensuring the scientific and rational construction of technology and quality can we achieve this.


Before the construction of artificial turf, the following factors should be mainly considered: the type of artificial turf, the fiber material (PP or PE) of the artificial turf used, the type of filler (silica sand, rubber particles, or a mixture of both), and the depth of filling; Design and so on.

(A) The choice of artificial turf type

The lawn surface of artificial turf can be divided into two types: mosaic type and woven type. The woven lawn is made of nylon and the finished product is blanketed. Compared with the inlaid tuft type lawn, the braided artificial turf has a complicated production procedure, the price is relatively expensive, the surface hardness of the lawn is large, and the buffering performance is not good, but the lawn is uniform and durable, and is very suitable for tennis, hockey, lawn bowling, etc. movement. Compared with woven lawns, mosaic-type lawns have longer and variable leaf-shaped fibers, ranging from 12mm to 55mm, and can be adjusted according to special needs. The grass is filled with quartz sand, rubber particles or a mixture of the two. The appearance and performance of the grass are similar to that of natural grass. It can be installed indoors or outdoors. It is suitable for football, rugby and baseball.

(II) Production materials and selection of artificial turf

Artificial turf is generally made of two materials: polypropylene and polyethylene. PP artificial turf is solid and has a low cushioning force. It is generally suitable for sports with less impact, such as tennis. The artificial turf of PE material is soft in texture, has good cushioning properties, and has little harm to athletes, and is suitable for sports activities with large impact such as football and rugby. It is also possible to mix two materials to produce artificial turf, so that the advantages of both can be combined to meet the needs of special competitions. For some high-intensity sports competitions, in order to improve the quality of the game and minimize the injuries of the athletes, when selecting the artificial turf, it is generally necessary to select a relatively high-fiber material, usually 25 to 50 mm, and select PE artificial turf or PE. / PP mixed material of artificial turf. In the construction of artificial turf sports grounds, when selecting the height of artificial turf, it is generally necessary to consider the overall budget of the stadium. Artificial turf, which is relatively high in height, is relatively expensive to construct and maintain. In many European schools, the height of the court is often chosen to be 19 mm. Turf, artificial turf height of 25 ~ 32mm can completely provide a high-quality sports ground, and artificial turf height of some professional sports field is usually selected in the 50 ~ 55mm, this height is usually considered the upper limit of the ideal artificial turf. In some American football stadiums, the height of artificial turf is higher, about 70mm, but in general, such a high artificial turf playing field is rare.

(3) Filling of artificial turf and selection of filling materials

The artificial turf filling material is usually sand or rubber granules, and sometimes the two are mixed and used. When the mixture is used, the ratio of the two is determined according to the specific circumstances, and the general mixing proportion is 70% rubber particles and 30% sand. In the past, 100% of sand was often used as a filler material in order to increase the stability of the turf base. However, as the artificial turf manufacturing process became more and more mature, its basic manufacturing was relatively complete, so the practice of stabilizing the turf with sand was used in the past. Has gradually been eliminated, now use more filling methods for 100% rubber particles. The filled sand or rubber particles are mostly of medium size and must be washed before filling. For some high-impact sports such as football, football, etc., the proportion of rubber particles should be appropriately increased to minimize the athlete's injury. For sports venues that have little or no impact, such as tennis courts, as long as the site is uniform in hardness, and the cushioning requirements are not high, there is a large margin in the selection of filler materials.

Fill depth The filling depth of quartz sand or rubber particles in the artificial turf can be determined depending on the purpose of use and the height of the selected lawn bundle. For sports with high impact strength, artificial turf with longer blade bundles can be used and filled with deeper fillers. Generally, the suitable filling depth of artificial turf is 5 mm from the tip of the blade; however, it is required to have high flatness and good homogeneity. In sports such as hockey, the leaf bundle can be properly reduced, the filling depth can be increased, and it can even be even with the lawn surface. According to a study by the University of Pennsylvania, the rebound of football and the surface hardness of the stadium on the artificial football court lawn can be controlled to some extent by the type of filler and the depth of filling.

(D) Artificial turf drainage design

Some artificial turfs are designed with a drainage system, and the turf cushion has permeability. The drainage layer is designed in the foundation layer. The construction structure of such turf is more complicated and the construction cost is higher. However, some systems do not have a designed drainage system. Therefore, it is necessary to rely on the natural slope drainage of the surface. Therefore, there is a high requirement for surface construction. Prior to the construction of artificial turf, in order to ensure the quality of the turf and economic efficiency, the above four factors should be the main consideration. In addition to these four main factors, there are other factors such as the handling of the grassroots and the choice of adhesives. In short, in actual project construction, various factors should be fully combined with factors such as the economic investment of the investor and the characteristics of the actual use of the lawn, relying on scientific theories and techniques to achieve the principle of economy, application, and effectiveness.
