Surface structure for athletic fields

Abstract

A surface structure for athletic fields capable of performing a drainage function and a shock-absorbing function at the same time is disclosed. The surface structure for athletic fields includes an underdrain (100) to drain groundwater and penetrating water to a sewer, a freezing prevention layer (200) to prevent the athletic field from freezing during the winter season, and a pebbled subsurface layer (300) spread on the upper surface of the freezing prevention layer (200). The surface structure further includes a shock-absorbing and drainage layer (400) placed on the upper surface of the subsurface layer (300) to drain rainwater and irrigation water and perform a shock-absorbing function to protect players.

Description

TECHNICAL FIELD [0001] The present invention relates, in general, to a surface structure for athletic fields and, more particularly, to a surface structure for athletic fields capable of performing a drainage function and a shock-absorbing function at the same time. BACKGROUND ART [0002] In recent years, participation in social sports has increased due to, for example, the recent trend of reduction in labor-time, causing an increase in the number of athletic fields for a variety of sports, such as soccer, baseball, tennis, volleyball, Jokgu, etc. [0003] The athletic fields for sports must be equipped with surfaces which can drain water, such as rainwater or irrigation water, and absorb shock, thereby protecting players on the fields from injury. Furthermore, in response to an increase in the use of artificial grass which is an all-weather surface material for athletic fields, surfaces with enhanced drainage and shock-absorbing functions are required.
