There are numerous specialized competitions in the construction of track and field facilities, each with its own set of specific rules and requirements. In addition to the competition rules, there are unique structural elements such as the long jump springboard, sand pit, pole vault insertion hole, 3000m obstacle pool, and inner ring drainage ditch. These structures are typically made of reinforced concrete, and their positioning and dimensions must be accurate to the millimeter. During construction, standard civil engineering methods are used, but any significant deviation can lead to major issues in the facility's functionality. If errors occur, it might require complete dismantling and rework, which is both time-consuming and costly. For instance, a 3000m obstacle pool had to be completely rebuilt due to misalignment with the running track. Therefore, from the very beginning of the project—right through the concrete pouring stage—every step must be carefully controlled. Track and field venues include a variety of components such as the long jump and triple jump springboards, sand pits, shot put circles, discus and hammer throwing areas, pole vault landing zones, and inner ring drainage ditches. Each of these requires precise planning and execution to ensure they meet international standards. The sequence of construction for each specialized structure is also crucial. Unlike general civil engineering projects, track and field structures are smaller in volume but demand high precision in location and elevation. Their placement often affects other ongoing work, potentially extending the overall construction timeline. For example, at a sports school in Beijing, the construction of the athletics field was poorly scheduled, leading to an eight-month project duration. In contrast, similar facilities 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 site. 2. Excavate and construct the inner ring trench, followed by the installation of the trench cover. 3. Lay the asphalt concrete layer. 4. Perform the 3000m obstacle pool slotting, long jump sand pit construction, take-off board installation, and the setup for shot put, discus, and hammer throw areas. Since asphalt concrete needs time to cure, this phase is best scheduled during that period. 5. Apply the plastic surface layer. 6. Conduct final inspections and obtain acceptance. Proper planning and attention to detail are essential to ensure the facility meets all performance and safety standards.
