There are numerous specialized competitions in the construction of track and field facilities. Each competition has its own set of specific rules, and the structures involved—such as the springboard for long jump, the sand pit, the pole vault insertion hole, the 3000m obstacle pool, and the inner drainage ditch—are all built with high precision. Most of these structures are made of reinforced concrete, and their positioning and dimensions must be accurate to the millimeter. In construction, standard civil engineering techniques are typically used, but even small deviations can lead to major issues during competition. If a structure is not built correctly, it may need to be completely dismantled and rebuilt, which can be both time-consuming and costly. For example, a 3000m obstacle pool was entirely removed due to misalignment with the running track. This highlights the importance of careful planning and precise execution from the very beginning of the project, right through to the final concrete pour.
Track and field venues include a variety of key components: the long jump and triple jump springboards, the sand pit, the shot put circle and area, the discus and hammer throwing areas, the pole vault insertion point, and the inner ring drainage system. Each of these elements requires strict attention to detail and proper sequencing during construction.
The sequence of constructing each specialized structure is also crucial. Unlike typical civil engineering projects, these structures are often small in size but require extremely accurate placement and elevation. Their construction can also occupy a large area, potentially interfering with other ongoing tasks on the site. This can lead to unnecessary delays in the overall project timeline. For instance, at a sports school in Beijing, the construction of the athletics field was poorly planned, resulting in an eight-month project. In contrast, under similar conditions, the same type of facility was completed in just four months.
Here is the detailed 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 board, shot put, discus, and hammer throwing areas. Since asphalt needs time to settle and release fumes, this phase is best scheduled during that period.
5. Apply the plastic surface coating.
6. Conduct final acceptance and inspection.
By following this structured approach, construction teams can ensure that all elements meet the required standards, avoiding costly rework and ensuring the venue is ready for competition.
