The obstacle area is generally composed of bunkers, pools, and trees. Its purpose is to punish players for inaccurate shots. Getting the ball out of the obstacle area is much more difficult than hitting the ball on the fairway.
The sandpit generally covers an area of 140-380 square meters. Some bunkers can be as high as 2400 square meters. Most 18-hole golf courses have 40-80 bunkers. It can be determined according to the needs of playing and the designer’s design ideas. The setting of the course bunker should conform to the natural strategy. Make players think of the correct location of the tee.
Usually the location of the fairway bunker is determined by the distance of the championship tee. The location of the bunkers should also be based on the drainage characteristics of the site. Sand pits should have good ground and underground drainage conditions. In the low terrain and underground drainage is sufficient. Or in an area with good water seepage conditions under the bunkers. The bunkers can be built below the level of the grass.
From the perspective of maintenance and management, the bunker on the side of the green should be set at a distance of 3 to 3.7 meters from the green lawn. In order to build the passage of machinery and prevent the sand in the bunkers from being blown onto the lawn by the wind. The thickness of the sand in the bunkers at the base of the green should be at least 10 cm. The thickness of the slope or raised sand layer of the bunker should be at least 5 cm. The sand thickness of the fairway bunkers is relatively shallow.
