During winter, it is essential to promptly clear away rain or snow from塑胶跑道 surfaces. If freezing is detected, avoid using hard objects to chip or pry, allowing it to thaw naturally. Moisture on the site should be removed immediately. In winter, it is crucial to keep the塑胶跑道 surface dry at all times. Particularly at night, sports facilities are prone to freezing. After using the塑胶跑道, promptly remove any surface moisture to prevent damage to the surface due to freezing.
The presence of light under the manhole cover during winter, where the temperature below the manhole cover is lower than that of the sports field, is a severe warning that occurs almost 99.9% of the time in northern regions. It can indicate the presence of numerous locations. The light manifestation beneath the manhole cover is actually due to the condensation of moisture, which is a reality that causes the plastic playing field foundation to decrease. The decrease in the plastic playing field foundation may be due to the expansion of gray soil, as the stone material layer and asphalt layer have voids, exposing moisture. Therefore, there are no signs of expansion, and the water stable and gray soil layers can retain liquids, leading to the warning of expansion.
It is essential to address snow accumulation as soon as possible during rainy and snowy weather. Once snow is present on the synthetic track, it should be cleared immediately to prevent the snow from freezing and damaging the track. After heavy snow has ceased, use a soft broom to clear the snow; avoid using hard snow removal tools, as they can harm the flatness of the synthetic track. Otherwise, it may lead to damage to the synthetic track.
The drainage pipes are relatively quiet in a fully equipped plastic playground, as the smoothness and quality of the drainage pipes are one of the factors that contribute to the same level of quietness as the plastic playground's good or bad condition. The top layer of the drainage pipes must be water-stabilized and have a soil layer to prevent cracking, and adding a mixture of 70% sand and 30% clay at the bottom of the drainage channel, if permissible, can economically manage this matter at a certain level.
Ice should naturally melt and be cleared away. If freezing occurs at night due to low temperatures, it is necessary to allow the frozen snow to naturally melt, but remember not to use hard objects to scrape it, as this may damage the entire surface of the plastic track. Additionally, it is crucial to immediately clear away any accumulated water during the melting process. Proper maintenance and care of the plastic track become especially important at this time. Ensure regular maintenance and care for the plastic track. Prevent environmental pollution from harmful substances, avoid strong mechanical impacts and abrasion, and prohibit vehicles from driving on the sports field, as well as stacking or lifting heavy objects.
