Due to its large span, multi-functionality, and intelligent integration, the installation of the sports extension hall involves collaborative work across multiple professional fields, including civil engineering foundations, main structure, electromechanical systems, sports surfaces, and intelligent control. Rigorous processes and technical standards must be followed to guarantee installation quality, safety performance, and the realization of subsequent functions.
Sufficient preparation and planning should be completed in the early stages of installation. Detailed technical briefings should be conducted based on design drawings and construction plans, clarifying the interfaces between various disciplines and the connection points between procedures. On-site measurement and layout must be verified with high-precision instruments to ensure that the positioning of foundation embedded parts and supports is completely consistent with the design. The large-span roof and main frame are mostly prefabricated components in the factory. Before arrival on site, their dimensions, materials, and weld quality should be inspected at the factory, and they should be stacked reasonably according to the hoisting sequence to prevent deformation or damage caused by secondary handling.
The installation of the main structure is the core step in the formation of the venue. For steel structure space frames or tubular truss systems, a combination of segmented hoisting and high-altitude assembly is typically used. During hoisting, deflection and lateral displacement must be monitored in real time to ensure overall geometric accuracy meets specifications. For tensile membrane roofs, the supporting frame must be fixed first, then tension is gradually applied according to the predetermined tensioning sequence and pretension value to achieve the designed membrane shape and stress distribution. Simultaneously, initial checks of airtightness and drainage performance are conducted. All structural connection nodes should undergo torque re-measurement and weld visual inspection after installation. Critical areas must undergo non-destructive testing according to specifications to eliminate hidden defects.
The installation of electromechanical and intelligent systems must be closely coordinated with civil engineering and structural construction. The reserved holes and loads for HVAC pipes, cable trays, and equipment foundations must be verified beforehand to avoid later chiseling and structural damage. Air conditioning units, fan coil units, and ductwork installations must ensure levelness and airtightness. Electrical wiring must distinguish between strong and weak currents and be properly grounded to prevent signal interference and safety hazards. Sensors, cameras, and actuators in the intelligent control system should be accurately positioned. After wiring is completed, path testing and signal calibration should be performed to ensure reliable data acquisition and remote control functions.
The installation of sports surfaces and venue facilities directly affects performance. Base treatment must be leveled, compacted, and tested for load-bearing capacity according to sports process standards. Then, wooden flooring, synthetic materials, or plastic surfaces should be laid according to the requirements of different projects, controlling the flatness and uniform thickness of joints. After completion, elasticity, coefficient of friction, and flatness should be tested. Tracks and drive devices for movable partitions, lifting stands, and folding seats must be precisely installed and lubricated, and operational tests should be conducted to ensure smooth switching and reliable locking.
Strict quality control and safety management must be implemented throughout the installation process. High-altitude operations must be carried out using compliant scaffolding and safety nets. Hoisting operations should be directed by certified personnel and a warning zone should be established. Each process must undergo self-inspection, mutual inspection, and specialized inspection after completion. Hidden works must be documented with photographic evidence and signed off by relevant parties. During the completion phase, a joint acceptance inspection should be organized, covering structural safety, electromechanical functions, sports performance, and intelligent systems, to ensure that all indicators meet design and specification requirements.
Overall, the installation of a sports extension hall is a multi-disciplinary, technology-intensive, and systematic project. Only by adhering to standardized operations and meticulous management in all stages of preparation, construction, and acceptance can a solid foundation be laid for the long-term safe, stable operation and functional performance of the venue.
