A complete hockey field system is very complex, including basic structures, site design, foundation acceptance, sprinkler systems, lighting systems, and fences.
Basic structure
As shown in the figure, the basic structure of the hockey field is artificial grass, rubber-cushioned cushion, fine asphalt, coarse asphalt, graded crushed stone layer, and compacted compaction of prime soil from top to bottom.
Site Design
Basic acceptance
According to the requirements of the vertical, horizontal slope and flatness requirements of the venue announced by the International Qualcomm and the China Quo Association, it can be used as the standard for the basic drainage gradient of the hockey rink.
The specific slope data is as follows:
1. Requirements for the vertical slope of the site
1.11 and 2 international standards:
1.21 and 2 national standards:
2. Requirements for the slope of the site
2.1 Level 1 and Level 2 International Standards:
2.2 Level 1 and Level 2 national standards:
3. Site flatness requirements
Place a three meter long side or straightedge in any direction. The maximum deviation of the surface above or below them must meet the following values:
3.1 Level 1 and Level 2 International Standard: ≤ 6mm
3.2 Level 1 and Level 2 national standards: ≤ 6mm
NOTE: There must be no significant height difference and there must be no cracks or gaps in the joints and seams. Acceptable height differences and cracks, gaps maximum 2 mm. Both the foundation and the cushion surface should provide the top turf with standards-compliant conditions to ensure that the flatness can be achieved at any time and anywhere on the site.
Sprinkler System
Due to the special needs of hockey, all hockey courts use artificial turf and require a complete lawn sprinkler system. In general, before the game or training, the venue must be watered to effectively reduce the friction of the players running, improve the ball rolling effect, but also conducive to the maintenance of the lawn itself.
Lighting system
The main part of the general outdoor stadium lighting system is the luminaire, and the hockey court belongs to the outdoor stadium. The distribution of the luminaires is generally determined according to no TV broadcast and TV broadcast.
1. The multi-bar arrangement should be adopted when there is no TV broadcast. The distance between the bottom of the pole and the sidelines of the venue should not be less than 4m, and the distance between the bottom of the pole and the bottom line should not be less than 5m. As shown below.
2. When there is a four-corner arrangement for television broadcasting, the position and height of the lamp should meet the requirements in the figure below. The position of the lamp post should be between 10° and 25°.
purse seine
1. Seine design
The fence is surrounded by a plastic cover, the color is dark green, the height of the fence is 1.2 meters, the fence behind the goal is 4 meters high, the mesh size is 45mm x 45mm, and the mesh diameter is 3.6mm. The upper and lower rails of the fence column adopt the national standard welded pipe and the height of the column is 1.2 meters.
2. Seine construction process
Preparation for construction → Net column welding → Welding of top and bottom rails → Construction of hanging nets → Construction of net doors → Painting → Site cleaning → Completion of acceptance
