There are numerous specialized competitions involved in the construction of track and field facilities. Each competition has its own set of specific rules and requirements, and the structures used for these events—like the long jump springboard, sand pit, pole vault insertion hole, 3000m obstacle pool, and inner ring drainage ditch—are all critical to the accuracy and fairness of the event. Most of these structures are made of reinforced concrete, and their placement and dimensions must be precise, often within millimeter-level tolerances.
In construction, standard civil engineering methods are typically used, but even small deviations can lead to significant issues during competition. For instance, a 3000m obstacle pool had to be completely dismantled because it was misaligned with the running track. This highlights the importance of precision from the very beginning of the project, right through to the final concrete pour. Every stage must be carefully controlled to avoid costly rework.
Track and field venues include various components such as the long jump and triple jump takeoff boards, sand pits, shot put circles and areas, discus and hammer throwing zones, pole vault landing areas, and the inner ring drainage ditches. Each of these elements plays a crucial role in the overall functionality and safety of the facility.
The sequence of construction for each specialized structure is also vital. Unlike general civil projects, these structures are smaller in scale but require high precision in location and elevation. Their installation often affects other construction activities, potentially extending the overall project timeline. For example, a sports school in Beijing once experienced unnecessary delays due to poor scheduling, resulting in an eight-month construction period, whereas similar projects elsewhere were completed in just four months.
Here’s a detailed breakdown of the construction process:
1. Complete the entire earthwork, subbase, and base course.
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 slots, long jump sand pits, takeoff boards, shot put, discus, and hammer throwing areas. Since asphalt requires some time to off-gas, this phase is best scheduled during that period.
5. Install the plastic surface finish.
6. Conduct final acceptance and inspection.
By following this structured approach, the quality, accuracy, and efficiency of the track and field construction can be significantly improved, ensuring that the venue meets the highest standards for competition.
