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 generally to surface structures for sports fields, and more particularly to surface structures for sports fields which have the function of water drainage and at the same time have the function of shock absorption. Background technique [0002] In recent years, more and more people participate in social sports due to recent trends such as reducing working hours, resulting in an increase in the number of sports fields for various sports such as soccer, baseball, tennis, volleyball, Jokgu, and the like. [0003] Playgrounds for sports must be equipped with surfaces that are capable of draining water, such as rainwater or irrigation water, and that absorb shocks, thereby preventing injuries to the players on the field. Furthermore, to accommodate the increased use of artificial turf (weather resistant surface material) for sports fields, these surfaces are required to have improved water drainage and shock absorption.

AI Technical Summary

Problems solved by technology

The water in the pores of the elastic layer freezes in winter, thus significantly reducing the shock absorption capacity of the elastic layer

[0007] Also, when water contained in the pores of the water-permeable layer of permeable concrete or permeable asphalt concrete freezes in winter, the volume of the water-permeable layer increases to cause freezing damage that leads to a decrease in the durability of the water-permeable layer

[0008] In addition, as time goes by, the pores of both the elastic layer and the water-permeable layer will be blocked by debris such as dust carried in with the water, so that the drainage capacity of the elastic layer and the water-permeable layer will be reduced

[0009] In particular, traditional surface structures for sports fields lead to excessive construction costs and requirements, as well as unduly long construction periods
