Composite plastic runway excellent performance to ensure the athletes in the games and training can get good grades, is one of the important reasons for this plastic runway flatness is very good ~ the flatness of the good and the bad is closely related to the plastic runway construction on the ground, to ensure the qualification rate of the ground construction, several aspects need to be a few times. This method applies to plastic racetrack, plastic basketball court, badminton court, tennis court and so on.
The standard unit of flatness is measured in millimeters. The tools to be used for the detection of flatness are: 3M straighter, requirements: the precision is up to 3MM, and the ruler is qualified without defects. Ground gauge: 0-25mm in length; Precision is up and down 1MM. Ground theodolite: accuracy is up and down 2 degrees. When measuring, the line of the ground is bounded by the line of the ground, and the straight path is marked with a point of 3MM in each direction. Bend, centered on the circle with theodolite every 5 degrees do a radial line, no radial lines, with straightedge placed between any two adjacent, plastic runway is measured with a feeler biggest local notch exceeds 4 mm, not more than 3 mm is the biggest sag. The number of measurements is not less than 40. At the end, the number of qualified points multiplied by 100 can calculate the acceptable rate of flatness.
