When building multiple parallel Rainbow slides, first rationally plan the spacing and overall width of each slide, reserving space for safe passage, emergency evacuation and equipment maintenance to prevent collisions and interference during sliding. Second, standardize the gradient, drop and length of all slides to ensure consistent sliding speed and user experience, while reinforcing the foundation and optimizing structural load-bearing for stability. In addition, install partition guardrails, anti-collision barriers and boarding/alighting buffer zones, and equip queuing areas, anti-slip walkways and emergency passages to ensure smooth crowd flow and safety. Finally, install proper drainage systems to avoid slippery surfaces caused by water accumulation, and take into account daily operation, equipment management, site ventilation and visual layout, in full compliance with amusement ride safety standards.
