First, disc-lock scaffolding is ideal for high-altitude construction: With a load-bearing capacity of 200kN, it provides a solid safety barrier. Intake towers and sluice gates of overseas hydropower stations are generally over 50 meters high. Under the dual challenges of lateral pressure and strong winds at high altitudes during concrete pouring, traditional scaffolding joints loosen, causing noticeable swaying and posing safety hazards. Disc-lock scaffolding uses disc-joint locking technology, achieving an axial load-bearing capacity of 200kN (equivalent to 20 tons) for the uprights and a tensile strength of 15kN for the joints. During the construction of the No. 3 intake tower of an international hydropower station, the 70-meter-high pouring platform remained completely stationary throughout the entire process. Safety inspections showed that the load-bearing capacity far exceeded design requirements, providing a 60% safety margin improvement compared to traditional scaffolding. This advantage stems from its unique joint design, which uses a locking mechanism to achieve a tight connection between the uprights and horizontal bars, effectively distributing the load and improving overall stability.
Secondly, the large span of the modular scaffolding: A 6-meter horizontal bar span frees up space for heavy machinery operations. The main powerhouses of overseas hydropower stations often have spans of 20-30 meters, requiring ample space to accommodate heavy equipment such as generators and gate hoists. Traditional scaffolding has a pole spacing of 1.5-2 meters, with dense poles obstructing machinery passage and reducing material transport efficiency. Modular scaffolding can achieve a 6-meter horizontal bar span, eliminating the need for additional poles. In the construction of the main powerhouse of an international hydropower station, a 3.5-meter pole spacing allowed a 50-ton crawler crane to pass directly, increasing equipment installation efficiency by 40% and shortening the construction period from 25 days to 17 days. This advantage stems from its modular design, which increases the length of horizontal bars while reducing the number of vertical bars, achieving efficient utilization of large span spaces.
Thirdly, the modular scaffolding’s ability to handle complex terrain: a 50cm adjustable base for precise leveling of sloping foundations. Overseas hydropower stations are often located in canyons and along riverbanks, with sloping foundations and stepped terrain being common. Traditional scaffolding uses bricks and gravel for leveling, which can easily lead to uneven stress and tilting of the scaffolding. Disc-lock scaffolding, with its high-precision adjustable base (adjustment range 0-50cm), can accurately level the scaffolding. During the construction of a hydroelectric power station in a canyon, facing a 30° sloping foundation, the construction team completed the erection of 500㎡ scaffolds in 2 days, controlling the horizontal error within 3mm. This saved 3 days of construction time compared to the traditional scaffolding method of “repeated leveling and adjustment,” and there were no safety hazards throughout the process. This advantage stems from its adjustable base design, which allows for precise leveling of the scaffolding by adjusting its height, adapting to complex terrain.
