Theodolite base slope detecting plastic track boundary from the start, the straights every 10m mark a set of points, the curve of a circle with the center point of a set of points marked every 15 °, within each set of points including the first and the eighth channel along the outer edge Two, the plastic runway, and then measure the water level elevation for each point, and calculate the height difference and two points on each set of the first and the eighth channel fellow adjacent points of elevation. It requires fundamental transverse runway longitudinal slope gradient ≤1 ≤1 ‰. Base flatness tests to the merits of plastic runway boundary is bounded straight in the lateral and longitudinal 3m mark each point, long-term production of plastic track stadium, turn to the center point of a circle, high quality composite plastic runway, using theodolite every 5 〃 make a radial lines, tennis courts plastic runway, each 3m mark a point, it will light up to 3m straightedge between any two adjacent points, with a feeler maximum local depressions, each measuring 30 points, and recorded on the site plan. Eligibility requirements flatness points (a feeler gauge readings ≤4mm) ≥85 more qualified. Plastic runway construction, plastic runway, Camry sports provided by the Dongguan City Camry sports facilities Engineering Limited. Dongguan City Camry Sports Facilities Engineering Co., Ltd.
