There are many special competitions in the construction of track and field venues. Each special competition has its own rules for the competition. At the same time, there are some special competition structures, such as the springboard for the long jump competition, the sand pit, the insertion hole for the pole vault, and the track In the 3000m running obstacle pool and the inner ring drainage ditch. Most of these structures are reinforced concrete structures, and the position and size requirements of the structures are in the millimeter (mm) range. In the construction, general civil engineering structures are used to construct the structures. Once the errors are too large, the recognition of the performance of the competition will be troublesome. Otherwise, it would have to be dismantled and re-dosed. There was a 3000m run obstacle pool that was completely dismantled due to misalignment with the runway. Therefore, in the construction of track and field venues, the construction of structures cannot be neglected from the beginning of the payout. Until the process of pouring cement concrete, each process must be strictly controlled. The track and field venues include: long jump and triple jump, springboard, sand pit, shot throwing circle and throwing area, hammer discus throwing and throwing area, pole vaulting and inserting point, and inner ring drainage ditch construction. The construction sequence of each professional structure is also very important. It is different from the general civil engineering projects because of the small volume of the structures, the high requirements for location and elevation, and the large construction footprint, which often affects other process operations. This will give the entire site construction period. Unnecessary extensions, such as the construction of an athletics field at a sports school in Beijing, were unreasonably arranged. The entire construction period lasted for about eight months, and the entire duration of the track and field field for the same conditions was completed within four months. The specific process is as follows: 1. The construction of the entire earthwork, subbase and grass-roots level is completed; 2. For the inner ring trench earthwork, trench structure, cover installation; 3. Laying asphalt concrete layer; 4. 3000m barrier tank slotting construction, long-distance sand pit construction, take-off board construction, shot throw, discus throw, hammer throw, etc. Since asphalt concrete requires a period of volatilization, it is most appropriate to arrange these projects during this period; 5. The plastic surface paving; 6. Closed acceptance.
