Description

Preparation method of curling racetrack

Technical Field

The invention relates to the field of curling, in particular to a preparation method of a curling track.

Background

Curling sports, also known as curling and skater skating, are a throwing competition item carried out on ice in a team unit, and are also winter-Olympic games. Generally, two small items are set for men and women, and each team comprises four persons. The curling is in a round pot shape and is made of Scotland natural granite without mica, all the natural granite for manufacturing the high-quality curling in the world is produced from a small island near the Scotland, and only Scotland masters the technology for manufacturing the top level curling in the world. Due to the limited field, curling sports can only be performed on ice in winter, and training cannot be performed outdoors in other three seasons, so that popularization of curling sports brings great obstruction.
