I. Hockey scene layer construction method
Natural grass and artificial turf are common in hockey scenes. The construction of artificial turf is now highlighted.
In the construction of artificial turf, first a layer of geotextile should be laid underneath to protect the wear between artificial turf and asphalt concrete. After the first turf is deployed, it is adjusted and then temporarily nailed to the asphalt concrete layer with a wooden strip outside the turf. The seams of the turf can be glued or stitched with a mechanical sewing machine. It is best not to work under hot sunlight at noon during construction to prevent the divot from shrinking and deforming.
After the artificial grass pavement is finished, the positions of the various parts of the competition line should be drawn according to the requirements of the site so that the artificial artificial grass seedlings can be replaced with white artificial turf. White artificial turf sticks to the green turf mat.
When artificial turf is applied, quartz sand shall be filled in the grass seedlings and the sand shall be layered. After each spread, use a bamboo basket to make a round trip. Put the overwhelming grass sprouts upright and place all the sand on the cloth. Sprinkle the second layer and apply the same method. Scatter the black rubber particles and black colloidal particles. After the end of the rafting, the bamboo raft should be used to make a round trip, and the place where the rubber particles are not uniform should be found by hand. After the completion of the entire field, athletes should be organized to enter the practice, use the venue in full, and after a period of time, replenish it with black rubber. Keep all the grass and plants upright, without exposure to quartz sand, and the length of exposed grass seedlings should be controlled at 10mm.
II. Facility construction methods for hockey court
When the hockey field is under construction, there are six flagpole insertion holes and four ball stud insertion points around the site, which need to be completed at the same time as the construction site, as well as the completion of the drainage ditch and water supply pipeline around the site. During the site construction, the construction process should be closely coordinated. There is a lot of problems with the early construction or the late construction. Such as the site of the drainage ditch, the location should be outside the hockey court in the limit line, so the best drainage after the completion of the bottom layer after the groove construction, can be opened into a straight groove, no fertilizer tank, to ensure the integrity of the grassroots, to prevent the fertilizer tank The backfilling is not good and there is a sinking phenomenon; after the completion of the drainage ditch, the permeated water structure is built. When pre-embedded sink drains, pay attention to the slope of the ditch method to prevent backwater from occurring.
After the construction of the grass-roots level, drill with an electric drill to correctly position the position of the flag pole and the goal post. After drilling, the steel pipe is embedded in the pipe, and the concrete is buried around the pipe. Do not fill the soil to prevent displacement.
