The site is designed as a double-layer sleeper structure with suspended paving. The lower sleeper is laid out along the long direction of the venue with a distance of 450mm. The upper sleeper is laid along the short direction of the venue, and the two sides are laid out parallel to the short side with a distance of 400mm; Reserve a 10--20mm wide expansion gap, and use rubber pads to cushion the sleeper joints.
