Hockey field size
The hockey field is mainly based on artificial turf, and the area of the field is similar to that of the football field.
It is 91.4m long and 55.0m wide. The long side is the edge, and the short side is the end.
The site marking should be white, the line width should be 75mm, and the line width should be included in the site.The distance between the two goal posts on the end line is the goal line.Buffer areas of 4.0m and 5.0m should be left outside the side and end lines of the playing field, respectively. There should also be a 4m wide off-site working area between adjacent competition venues
The main marking lines in the court are: shooting arc, 22.9 meter line (25 yard line), center line, penalty spot, etc.
Sign line
The line connecting the midpoints of the two sidelines is the centerline
22.90m away from the centerline, connecting 2 22.9m lines
On the outside of the end line, 1.83m away from the midpoint of the end line, draw a 150mm mark line (the distance from the inner edge of the mark line to the midpoint of the end line)
A penalty point with a diameter of 150 mm is drawn at 6.40 m in front of the midpoint of the goal line.
Draw a 3.66m long marking line directly in front of the midpoint of the end line, parallel to the end line, 14.63m from the end line (the above distance is the distance from the outer edge of the marking line to the outer edge of the end line); The angle is the center of the circle, and the line is extended to both sides to make it intersect with the end line, and each forms a 1/4 arc. This line is called the shooting arc.
A dotted line is drawn 5m away from the arc. The length of each solid line is 300mm, and the interval between the solid lines is 3m.
Facilities
The goal shall be set in the middle of the end line of the court, the columns and beams shall be rectangular, the cross-sectional area shall be 51x75, and the color shall be white. The beam is 3.66m long, the column height is 2.14m, the beam depth is not less than 0.90m, and the ground depth is not less than 1.20m
A side baffle with a length of not less than 1.20m and a height of 460m is placed on the ground on the side of the net and fixed to the back of the goal post at a right angle to the end line. Its thickness does not exceed the width of the post. The back of the net is set with a 3.66m long and 460m high tailgate, which is connected to the side fences on both sides and placed on the ground. Both the side and rear baffles need to be painted dark.
The ball net is secured on the back of the goal post and is connected to the side fence and the tail fence. The distance between the hooks should not exceed 150mm, and the mesh should not be greater than 45mm.
A flag pole with a height of 1.2m-1.5m shall be set at each corner of the playing field and shall be placed on a spring seat. The length and width of the flag shall not exceed 0.3m.
Fence nets shall be set around the site, with a net height of 1.0m; high nets shall also be installed outside the fence nets, the net height shall not be less than 6.0m, the distance between the posts of the high net shall be controlled at 3.0m-3.5m, and the size and spacing of the posts shall be combined with the wind power of each place Depending on the specific situation.
Hockey artificial turf
Hockey grass is the most demanding product in the artificial grass product range. Hockey grass is very different from the football grass or leisure grass we are familiar with. Due to the characteristics of its hockey sport, its grass should meet the requirements of good water retention, water permeability, and Strong wear resistance, excellent flatness, anti-aging and weather resistance, and high grass density, no direction, and keep the direction of the ball's movement at all times. There are also many requirements for the paving technology of the venue. Among them, the double requirements of both water seepage and water retention have put forward a new test for the construction. According to the requirements, the surface of the court retains an average of 3mm of water after 35 minutes of watering, and any place The amount of water should not be less than 2mm. To this end, it is recommended to use the five-layer paving method of lime, coarse asphalt, medium asphalt, rubber particle damping layer, and artificial grass to meet the following basic requirements.
Characteristics of hockey artificial grass
1.Good water retention and permeability;
2. Extreme wear resistance and long service life;
3.Excellent flatness, anti-aging and weather resistance;
4. High grass density, no direction, keep the ball moving direction;
5. Thick cushion layer, excellent sports performance and foot feeling;
6.Environmental protection, no pollution, no fading;
7. The surface of the artificial grass is shiny and not dazzling;
8. There are few seams and no traces.
