It features versatility, efficiency, high load-bearing capacity, and safety and reliability.
1. Mechanical Design: How does it meet the unique load requirements of hydropower stations?
Scaffolding used in hydropower station construction must withstand a variety of complex loads. Through meticulous mechanical design, the scaffolding system successfully meets these challenges. The scaffolding system utilizes Q345B high-strength steel for its uprights, which exhibits excellent mechanical properties and an axial compressive strength of up to 200kN. In heavy-load scenarios such as dam concreting, other types of scaffolding may deform or even collapse due to the immense pressure. However, the high-strength uprights of the scaffolding system can stably support the various loads encountered during construction, ensuring safety. The arrangement of diagonal braces is crucial for scaffolding stability. The 360° adjustable diagonal braces of the scaffolding system create a stable triangular structure. According to data from the “Study on the Stability of Disc-type Scaffolding,” this structure has a 40% higher anti-overturning coefficient than traditional scaffolding. Hydropower station construction often faces adverse factors such as strong winds and vibrations. The diagonal rod arrangement of disc-type scaffolding effectively resists these external forces, maintaining the scaffold’s stability and providing a safe and reliable working platform for construction workers. Joint connections are a key component of scaffolding’s mechanical performance. Disc-type scaffolding utilizes a wedge-shaped plug + self-locking pin connection method, which offers strong pullout resistance (≥3kN). Unlike traditional scaffolding’s bolted connections, disc-type scaffolding avoids joint failure caused by loose bolts. During long-term construction, bolts are easily loosened by factors such as vibration, wind, and sun. Once a joint fails, the stability of the entire scaffolding is seriously threatened. However, the disc-type scaffolding connection method consistently maintains joint stability, ensuring the safety of the scaffolding.
2. Construction Specifications: Key Points for the Entire Process, From Foundation Preparation to Acceptance
A standardized construction process is fundamental to the safe use of interlocking scaffolding, and every step must be considered. Regarding foundation preparation, hydropower stations are often located in mountainous areas with complex foundation conditions, and soft soil is common. For these types of foundations, a 10cm concrete cushion is required to increase the foundation’s load-bearing capacity and stability. Furthermore, the leveling error of the adjustable base must be controlled to ≤5mm to ensure a flat base and avoid uneven loads caused by an uneven base, which could affect the scaffold’s overall stability. During scaffolding erection, controlling the vertical deviation of the uprights is crucial and must be kept within 1/500. Excessive vertical deviation can alter the scaffold’s load-bearing state, increasing safety risks. When the crossbar spacing is 1.5m, vertical diagonal bars must be installed at each level to enhance the scaffold’s overall stability and enable it to better withstand various loads. Safety inspection is the final hurdle in ensuring the safe use of interlocking scaffolding. Referencing the JGJ/T 231-2021 standard, the focus is on checking the locking rate of the latches. Pins must be 100% in place. The locking of the latches directly affects the joint strength and overall stability of the scaffolding. Also, the height of the sweeping rods from the ground must be checked and must be ≤300mm. Sweeping rods enhance the stability of the scaffolding base and prevent sway. Only by passing a rigorous safety inspection can the interlocking scaffolding be guaranteed to operate safely and reliably during construction.
3. Cost-effectiveness: How to balance long-term investment with short-term benefits?
Cost-effectiveness is a key consideration when choosing scaffolding. Although interlocking scaffolding has a higher initial cost, its overall cost advantage is significant in the long term. The unit price of interlocking scaffolding is approximately 2,000 yuan per ton, twice that of traditional scaffolding, which can lead many to initially be concerned about the cost. However, under a rental model, its daily rental cost is only 1.5 yuan per ton, making it ideal for long-term use in hydropower projects. Hydropower projects have long construction periods, and leasing can significantly reduce initial investment costs. Furthermore, the durability of the interlocking scaffolding minimizes wear and tear during the rental period.
Beyond the rental cost advantage, interlocking scaffolding offers numerous hidden savings. Field data from a hydropower station shows that the use of interlocking scaffolding reduced losses from safety accidents. Its stable structure and high safety performance significantly reduced safety risks during construction, minimizing casualties and property damage caused by accidents. Furthermore, the interlocking scaffolding’s high efficiency in erection and dismantling shortens construction schedules, bringing additional benefits to the project. Overall, the interlocking scaffolding achieved a 25% reduction in overall costs compared to traditional solutions, demonstrating its excellent balance between long-term investment and short-term benefits.
