In the construction of athletic fields, there are numerous specialized competitions that require precise structural setups. Each competition has its own specific rules and requirements, and the structures involved—such as the long jump springboard, sand pit, pole vault insertion hole, 3000m obstacle pool, and inner ring drainage ditch—are all critical to the event's success. Most of these structures are made of reinforced concrete, and their positioning and dimensions must be accurate to the millimeter. During construction, standard civil engineering techniques are typically used, but any deviation can lead to serious issues in the competition's performance. In some cases, entire structures have to be dismantled and rebuilt, which is both time-consuming and costly. For example, a 3000m obstacle pool was completely removed due to misalignment with the track. Therefore, from the very beginning of the project, every step—from layout to concrete pouring—must be carefully controlled. The structures involved in an athletic field include the long jump and triple jump springboards, sand pits, shot put circles, discus and hammer throwing areas, pole vaulting landing zones, and the inner ring drainage ditches. These elements are not just part of the design—they are essential for the safe and fair conduct of the events. The sequence of construction for each specialized structure is equally important. Unlike general construction projects, athletic field work involves small-volume structures with strict location and elevation requirements, often leading to a larger footprint and potential interference with other tasks. This can significantly extend the overall project timeline. A case in point is a sports school in Beijing, where the construction of the athletic field was poorly scheduled, resulting in an eight-month timeline. In contrast, under similar conditions, another field was completed in just four months. Here’s a breakdown of the typical construction process: 1. Complete the earthwork, sub-base, and base course for the entire site. 2. Excavate and construct the inner ring trench, install the trench structure, and place the cover. 3. Lay the asphalt concrete layer. 4. Construct the 3000m obstacle pool, long jump sand pit, takeoff boards, shot put, discus, and hammer throwing areas. Since asphalt requires a period of curing and volatilization, it’s best to schedule these tasks during this phase. 5. Install the plastic surface layer. 6. Conduct final inspections and obtain acceptance. Proper planning and execution at every stage ensure that the venue meets the exact specifications required for competitive athletics.
