In 1957, Wuhan Yangtze River Bridge Upon its completion, Mao Zedong hailed it as “a bridge spanning north and south, turning a natural barrier into a smooth thoroughfare,” vividly capturing Wuhan Yangtze River Bridge its majestic grandeur and the important role it plays in China’s north–south transportation. In the poem, “one bridge” refers to Wuhan Yangtze River Bridge ， “The word ‘qian’ means a trench or ditch used for transportation. The phrase ‘A bridge spans north and south, turning a natural barrier into a thoroughfare’ means that after the Wuhan Yangtze River Bridge was completed, The formidable barrier of the Yangtze River Become a smooth, unobstructed highway.

The “cable-stayed hanging basket” designed and manufactured by Dongfeng Shijing Template Group Co., Ltd. is a truly remarkable tool that turns seemingly insurmountable barriers into smooth, accessible routes in bridge construction. “The suspended-cable formwork system” is also one of the company’s high-quality, independently developed and manufactured products that has been granted a national patent.      

The launching gantry is the primary equipment used in cantilever construction and can be classified, according to its structural configuration, into four types: truss-type (including flat-chord designs without counterweights, diamond-shaped, triangular, and bow-string configurations), cable-stayed type (including triangular cable-stayed and prestressed cable-stayed designs), steel-section type, and hybrid type. The choice of launching-gantry structural configuration is determined by comprehensively comparing the characteristics, weight, types of steel used, and construction procedures associated with each type, in accordance with the requirements of the concrete cantilever-construction process and the design drawings for the launching gantry. Launching-gantry construction does not occupy any roadway or waterway surface, eliminating the need to interrupt traffic on main and auxiliary roads or navigation on waterways. Instead, the “launching gantry” moves along the structure, enabling the cast-in-place concrete box girders to be formed within it. During each pour, workers place 2 to 8 meters of concrete; once the bridge superstructure has hardened and attained sufficient strength, hydraulic mechanisms advance the launching gantry forward, after which a new segment of the girder is poured.

Design principles for the hanging basket include: light self-weight, simple structure, robustness and stability, ease of forward movement and assembly/disassembly, high reusability, minimal deformation under load, and ample clearance beneath the basket to provide a large working platform, thereby facilitating reinforcement and formwork operations.

Liuchuan Town, which is under the jurisdiction of Jianhe County in Guizhou Province, is located Jianhe County The northwest region is primarily inhabited by the Miao, Han, Dong, and Shui ethnic groups. The entire town Forest coverage Forest resources are abundant, accounting for as much as 64% of the total. The Qingshui River is the largest river in Qiandongnan Prefecture, Guizhou Province, and belongs to the Dongting Lake drainage system within the Yangtze River basin. The river flows through Liuchuan Town, where steep, densely forested mountains line its banks, speedboats dart back and forth across the water, and fish swim freely in the clear currents, creating a stunningly beautiful landscape.

Recently, the key control project along the entire line, the Guizhou Jianrong–Rongjiang section, The concrete pouring for Segment 1 of Girder No. 3 on the No. 4 Main Tower of the Qing Shui River Super Bridge has been completed, marking the official commencement of construction on the bridge. Cantilever Hanging Basket Construction phase.

The segmental cantilever construction for the Qingshui River super-large bridge adopts Long-Platform Composite Cable-Suspended Formwork , marking the first time this construction technique has been employed on a cable-stayed bridge within China Communications First Public Works Bureau Group. To ensure the smooth execution of the bridge’s cantilever construction using hanging baskets, Dongfeng Shijing Formwork Group assigned technical personnel to maintain close communication with the project team, refine the construction plan, conduct thorough safety and technical briefings, and provide on-site guidance throughout the installation and commissioning of the hanging-basket formwork and cable-stay anchorages, thereby guaranteeing Suspension Basket Safety and quality during the construction phase.

Qingshui River Grand Bridge The main bridge is the main span. A 300-meter-long, twin-tower, central double-cable-plane prestressed concrete cable-stayed bridge with “tower–girder–pier integral connection” features a single-box, five-cell prestressed concrete girder. The superstructure of the main bridge is divided into a total of 97 girder segments: segment No. 0 and the 24th segment of the side span are constructed using the scaffolding cast-in-place method, the mid-span closure segment is erected using the suspended formwork method, and all other segments are constructed using Front-pivot hanging basket cantilever casting Construction method.

I wonder if, after reading the editor’s article, you truly understand tomorrow, “Turning a natural barrier into a thoroughfare” is achieved through “cable-stayed suspended baskets.” Could this amazing tool be the one to help make it happen?
