探析田径跑道内突沿可以取消

Exploration on the Cancelation of Inner Edge Kerb on Track

内突沿是田径运动场的组成部分,起分隔草坪、跑道的作用。对于以前的煤渣跑道来说,内突沿拥有巨大的保持田径跑道外形和保护黄土、煤渣等材料不流失的作用,同时可以阻挡场内泥沙等杂质混入跑道影响跑道的整洁和质量。而对于现在大规模普及的塑胶跑道,并不存在材料流失的风险。通过分析发现随人类科技进步内突沿已发挥不了什么作用。

The inner edge turb is an integral part of the athletics field,which separates the lawn and the runway.For the former cinder track,the inner turrets have great effect on maintaining the shape of track and field runway and protecting the loess and cinder. It can also prevent impurities such as mud and dirt from entering the runway to influence the cleanliness and quality of the runway. And there is no risk of material loss for the widespread plastic runways nowadays. It is found that with the technological progress of technology,the role of inner edge kurb is becoming very limited.
