国际赛马跑道由三个专用跑道构成,其中T1绿茵赛马跑道共2.4km,直线段1.4km;T2、T3泥地跑道共计3380km;赛马跑道排水渠共计7200m,设计排水功能满足50年一遇降雨量排水2h内完成;排水渠底坡度3%,沟顶坡度与赛马跑道坡度相适应,赛马跑道西底东高,东区弯弧跑道横断面坡度5%,西区弯弧段横断面坡度3%,排水渠顶部完成面标高与跑道完成面标高允许偏差20mm;跑道市政排水口分散,排水渠底排水方向复杂多变,排水渠环形里程长,沟底坡度与沟顶坡度采用双曲率标高控制。
The international race track consists of three special runways, of which the T1 Green Race Track has a total length of 2.4km and the straight section of 1.4km; the T2 and T3 mud runways total 3,380km; the race track runways total 7200m and the designed drainage function meets the 50-year rainfall Drainage within 2h; Drainage bottom slope of 3%, ditch slope and the race track gradient to adapt to the raceway runway west of the East High, the eastern section of the curved runway gradient of 5%, West section of the curved section of the cross-section gradient of 3% Drainage of municipal runway is scattered, the draining direction of drainage channel bottom is complicated and changeable, the length of drainage channel ring is long, the ditch bottom slope and ditch slope slope are controlled by hyperbolic height.
