In the export construction industry, high-rise, large-span, and complex terrain construction has become the norm. Traditional steel pipe scaffolding can no longer meet the demands in terms of safety, efficiency, and adaptability. Disc-lock scaffolding, with its unique design and performance, has become the “optimal solution” for solving these problems. This article, combining practical cases and data, deeply analyzes the three core advantages of disc-lock scaffolding from three dimensions: mechanical performance, space utilization, and terrain adaptability.
First, High-Rise Structure Construction: 200kN Load-Bearing Capacity, Building a Solid Safety Line at High Altitudes. The 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, exhibiting obvious swaying and posing safety hazards. Disc-lock scaffolding uses disc-joint locking technology, with 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 its load-bearing capacity far exceeded design requirements, resulting in a 60% safety redundancy improvement compared to traditional scaffolding. This advantage stems from its unique node 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, large span space: A 6-meter horizontal bar span frees up space for heavy machinery operations. The main powerhouse spans of overseas hydropower stations are often 20-30 meters, requiring ample space to accommodate heavy equipment such as generators and hoists. Traditional scaffolding has an upright spacing of 1.5-2 meters, with dense uprights obstructing machinery passage and reducing material transportation efficiency. The disc-lock scaffolding can achieve a 6-meter horizontal bar span without the need for additional uprights. During the construction of the main powerhouse of an international hydropower station, the 3.5-meter spacing between uprights allowed a 50-ton crawler crane to pass directly through, 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 reduces the number of uprights by increasing the length of horizontal bars, achieving efficient utilization of large-span spaces.
Thirdly, complex terrain: 50cm adjustable base for precise leveling of sloping foundations. Overseas hydropower stations are often located in canyons and along riverbanks, where sloping foundations and stepped terrain are common. Traditional scaffolding uses bricks and gravel for leveling, which easily leads to uneven stress and tilting of the scaffolding. The high-precision adjustable base (adjustment range 0-50cm) of the disc-lock scaffolding can accurately level the ground. During the construction of a canyon hydropower station, facing a 30° sloping foundation, the construction team completed the erection of 500㎡ m of scaffolding in 2 days, controlling the horizontal error of the scaffolding 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 the base height, adapting to complex terrain.
In conclusion, with its three core advantages—high load-bearing capacity, large span, and strong adaptability to complex terrain—the disc-lock scaffolding is becoming a new favorite in the export construction industry. Choose it for more efficient and safer overseas project construction!
