For many people, the CAD construction design of the artificial turf football field is not very clear. In fact, as long as there is contact, it is easy to understand. A football field construction map includes lawn paving, foundation construction, drainage system and so on. The following figure is used to interpret the design of the artificial turf football field.
Generally, when I see the design drawing, it is obvious that this design is an 11-a-side football field. The length of the line is 86 meters and the width is 46 meters. The length of the playground is 120.5 meters and the width is 50 meters. 2 meters wide, the semicircle on both sides of the goal is 17.25 meters from the sideline, the radius of the semicircle is 24.8 meters, the radius of the center circle is 6.4 meters, the length from the center line to the side line is 43 meters, the width from the center point to the sides is 23 meters, the center to the restricted area line It is 31.5 meters, the bottom line of the two sides is 11.5 meters away from the restricted area, the length of the restricted area is 28.2 meters, the width of the restricted area is 12.8 meters, the width is 3.85 meters, and the distance from the penalty line is 7.7 meters.
The second part is the artificial turf practice; the first is the artificial turf field foundation, the plain soil is mechanically compacted, the compaction coefficient is not less than 93%, the 375px thick gravel cushion is filled after the tamping plain soil, and the 450px thick 砼 strength grade is C25 concrete, and maintained at a temperature of 20 degrees for 28 days, the compressive strength is not less than 25Mpa. After the concrete is laid, the SPEE cushion is placed, and the artificial lawn is filled with 50px thick quartz sand and 25px thick environmental rubber particles.
The third part is the practice of flat teeth; the flat teeth are placed between the field and the plastic runway, which is the connection between the site and the runway, and can protect the site, which is beneficial to the rainwater of the site and convenient for drainage. The plain soil is also mechanically compacted with a compaction coefficient of not less than 93%. It is coated with 375px gravel cushion and 250px C25 strength concrete, and then coated with 50px thick 1:3 dry hard cement mortar (dry hard cement mortar is The cement mortar with low slumping degree, that is, the water added during mixing, is less. The one meter high loose hand falls freely on the ground and spreads into scattered particles. “Hands hold a group and bloom,” and the mortar is prepared according to this state. The former is a common mix mortar, and the top surface is covered with 60x15x20 thick burnt surface dark gray granite flat teeth, and the polished granite has good color.
The CAD design of a complete artificial turf football field is probably the same. Of course, this is a simple design, and there are more complicated things, such as the drainage system and a few five-person venues in an 11-a-side venue.
