In the construction of track and field facilities, there are numerous specialized competitions, each with its own set of regulations. These competitions require specific structures such as the long jump springboard, sand pit, pole vault insertion hole, 3000m obstacle pool, and inner ring drainage ditch. Most of these components are made of reinforced concrete, and their placement and dimensions must be accurate to the millimeter. In general construction, standard civil engineering methods are used, but even minor deviations can cause significant issues during competition, potentially leading to costly rework or complete demolition. For instance, a 3000m obstacle pool was entirely removed due to misalignment with the running track. This highlights the importance of precision from the very beginning of the project, right through to the final concrete pour.
The structures involved in track and field venues include the long jump and triple jump springboards, sand pits, shot put circles, discus and hammer throwing areas, pole vault insertion points, and inner ring drainage systems. Each of these elements requires careful planning and execution to meet strict standards.
The sequence of construction for these specialized structures is equally critical. Unlike regular civil projects, these structures are often small in size but demand high accuracy in positioning and elevation. Their installation can also affect other ongoing tasks on site, potentially extending the overall construction timeline. For example, a sports school in Beijing experienced unnecessary delays, with the entire project taking around eight months. In contrast, similar projects under the same conditions were completed in just four months.
Here’s a detailed breakdown of the construction process:
1. Complete the earthwork, sub-base, and base layer for the entire area.
2. Excavate and construct the inner ring trench, followed by the installation of the trench cover.
3. Lay the asphalt concrete layer.
4. During the period when the asphalt is curing, perform the construction of the 3000m obstacle pool, long jump sand pit, take-off boards, shot put, discus, and hammer throwing areas.
5. Apply the plastic surface coating.
6. Conduct final inspections and accept the project.
Each step must be carefully managed to ensure the facility meets the required standards for both safety and performance.
