A kind of shot put sports field structure and preparation method thereof

Abstract

The invention discloses a shot put field structure and a preparation method thereof. The shot put field structure provided by the present invention not only has excellent rebound time, but also ensures that referees have sufficient time to measure without affecting the progress of the game. In addition, the shot put field structure of the present invention can also ensure the The shot put does not have the problem of bouncing back, thereby ensuring the fairness and justice of the game, and can meet the needs of high-standard and high-demand shot put sports venues.

Description

technical field [0001] The invention relates to a shot put field structure and a preparation method thereof. Background technique [0002] The landing area of ​​the shot put competition in traditional sports venues is paved with cinders, grass or various materials that can leave traces of the shot put, but it is easy to appear that the landing marks are not obvious, and the marks are not easy to recover, leading to problems such as misreading and affecting the fairness of sports competitions. , Fairness. With the advancement of technology, the current shot put area begins to use polyurethane material. Polyurethane material is a kind of polymer with special viscoelastic properties. It will form a certain mark when it is put on, and it can be read as a specific material, but this kind of deformation recovery time is long, which is not conducive to the progress of the game, and although the current shot put sports field has added slow rebound polyurethane material, it is still...

Problems solved by technology

[0002] The landing area of ​​the shot put competition in traditional sports venues is paved with cinders, grass or various materials that can leave traces of the shot put, but it is easy to appear that the landing marks are not obvious, and the marks are not easy to recover, leading to problems such as misreading and affecting the fairness of sports competitions. , impartiality

With the advancement of technology, the current shot put area begins to use polyurethane material. Polyurethane material is a kind of polymer with special viscoelastic properties. It will form a certain mark when it is put on, and it can be read as a specific material, but this kind of deformation recovery time is long, which is not conducive to the progress of the game, and although the current shot put sports field has added slow rebound polyurethane material, it is still difficult to completely Absorb the impact caused by the shot put on the ground, so that the shot will bounce back after it hits the ground, resulting in inaccurate measurement and directly affecting the results of the game
