Advantages of artificial turf artificial turf has the appearance of bright, four green, vivid, good drainage performance, long life, and low maintenance costs. Artificial turf sports systems for basic quality requirements are mainly concentrated in three areas: hardness, flatness and drainage slope. Commonly used artificial grass foundation has three categories: asphalt base, concrete base, gravel base, the use of which type is mainly determined by the local climate and the budget, time, asphalt base is particularly suitable for large temperature difference between north and low winter temperatures climate, but also because of its high cost, the warm and humid environment is not the most suitable type of base, gravel base because of its simple construction, low cost, rapid drainage, more common in the South, but because of its poor rigidity and stability, After prolonged use of prone to looseness, leading to uneven foundation; therefore, most of the domestic area Huludao outdoor basketball, cement concrete became the basis of economical and practical, very high cost of artificial turf base type. Double and sport artificial turf system based on a wealth of experience, cement concrete base on the artificial grass follows a brief introduction: 1, on the basis of the higher surface flatness requirements to ensure consistent artificial grass surface layer thickness, elasticity uniform. Flatness pass rate above 95%, 5 m straightedge error 3MM, slope: horizontal 8 ‰, longitudinal 5 ‰, semicircular area 5 ‰, the surface should be flat, smooth, ensure drainage. 2, the base should have a certain strength and stability. 3, the surface uniformly solid, no cracks, no bad side pockmarked face, straight and smooth seams to about 6000mm × 6000mm cuts as well. 4, cushion compaction, density of greater than 95%, after the medium-sized rolling machine pressure Huludao outdoor basketball, no significant wheel tracks, no loose topsoil, waves and other phenomena. 5, cement foundation must have impermeable layer, new PVC thick impermeable layer impermeable film Huludao outdoor basketball, junction should be greater than 300mm, edge margin greater than 150mm. 6, consider leaving expansion joints, width of 5 mm. 7, base maintenance period of 2-3 weeks. Playground Equipment Safety Standards entertainment in many accidents, there are many entertainment led to the. Cause and effect of these standards did not play equipment tend to be the beginning of the tragedy. Take one part 1. Security insurance policy rides in the air operation, the overall structure should be solid and reliable, the important parts of an insurance policy should take. 1m above the ground closed cockpit doors, it must be set by people inside can not open two or locking device with a locking device insurance. Import and export of non-enclosed cockpit at Landang matter, the insurance should also be belt locking device. 2. The safety restraint devices by people rides when running, by people are likely to be moved within the riding, collision or be thrown out when slide, must be provided by people bound devices. For more dangerous rides, as necessary, consider setting two separate tethering device. It can be used seat belts, safety pressure bar, lever and so on. Tethering device: should be reliable, comfortable, direct contact with the member by people with appropriate flexibility. Tethering device shall be designed to prevent a site by people being pinched or crushed, should be readily adjusted, easy to operate. Belt: can be used alone or lift slightly slower swing, no flip has not been thrown on dangerous facilities, use of seat belts should generally be equipped with auxiliary handle. For sports facilities intense, seat belt restraint device can be used as an auxiliary. Safety pressure bar: When you run the rides, it may cause people take the risk of being left out, you must set the appropriate type of safety pressure bar; safety pressure bar itself must have sufficient strength and locking force, to ensure that no tourists were thrown or Huludao fall outdoor basketball, and stopped in front of the device is always locked. 3. Of the security fence, the site safety requirements should be set into a safety barrier, respectively, exports should be established at the inlet guide fence. Measures should be non-slip platform. Security gates opening direction should travel agreement (except in exceptional circumstances) direction by people. To prevent closing the gap caused by injury, the door between the border and the uprights should be appropriate, or take other protective measures for hand staff.
