Shot sports field structure and preparation method thereof

Abstract

The invention discloses a shot sports field structure and a preparation method thereof. The shot sports field structure provided by the invention has excellent rebound time, ensures that a referee hassufficient time to measure, and simultaneously does not influence the progress of a competition. In addition, the shot sports field structure can also ensure that the shot after falling to the grounddoes not have the rebound problem, thereby ensuring the fairness and fairness of the competition and meeting the requirements of the shot sports field with high specification and high requirement.

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
