Engineers are working to stabilize a 400-ton bridge tower component for the Shenzhen-Zhongshan Bridge. Current efforts aim to develop standardized modules that can be transported and precisely connected at heights of 100 meters, though this approach lacks industry precedent. This process is in the industry and relies on technological innovation to overcome the limitations of traditional manual construction methods. The project requires breaking down complex, changing three-dimensional structures into standardized modules for transport and assembly. Researcher Cheng Maolin proposed using horizontal sections to split multi-layer structures into single layers that can be unfolded into two assemblable planes. The core challenge involves ensuring the precision of the connection between steel bars is controlled within 3 millimeters.

Cross-border passenger volume on the Guangzhou-Shenzhen-Hong Kong high-speed rail has continued to rise.

Cheng Maolin led a team that successfully developed the world's first intelligent rebar production line in June 2020. The project aims to address the complexity of diverse bridge tower shapes in China, where no two bridges are identical.

Chinese electric vehicle manufacturer BYD presented financial figures yesterday showing its seventh poor quarterly performance in three years. The report comes as Europe maintains its 2035 deadline to phase out fossil fuel vehicles.

Huawei is seeking orders for its Ascent 950 chip to bypass US export controls on Nvidia hardware. DeepSig released the B4 model on April 24, which is optimized for Huawei hardware. Huawei expects to ship approximately 750,000 units of this chip this year.

A smart production line for rebar placement and an integrated intelligent tower crane have been deployed for the Shenzhen-Zhongshan Bridge project. A new intelligent rebar welding technology has been developed to fill a gap in industrial construction equipment. Cheng Maolin led a team that successfully developed the world's first intelligent rebar production line and an integrated intelligent tower crane system since June 2020. The robot addresses risks associated with manual welding of steel mesh, which contains at least 1,600 weld points per sheet. The technology aims to prevent steel mesh from falling from heights of 200 to 300 meters during construction. New automated rebar laying technology has filled a technical gap in industrial construction for both domestic and international markets.

The Liba Zhou proxy team has developed a new mechanical structure featuring a flexible and strong joint system for tower crane climbing. The system features an eight-layer circular construction platform with distinct functions, enabling zero-idle operation at a height of 79 meters. The innovation aims to improve safety and efficiency by allowing for zero-idle rotation at 79 meters high. This new system is lighter, less expensive, more aesthetically pleasing, and easier to operate than previous versions. Li Bazhou's team developed a new precast steel reinforcement component mechanized production line, overcoming challenges in connecting steel bars. China has developed technology for producing special steel plates with thicknesses greater than or equal to 450 millimeters. These plates are for key structures and require exceptional toughness and strength.

A 400-ton casting machine used for the Shenzhen-Zhongshan Bridge construction successfully completed a zero-rotation turn at an altitude of 79 meters. The operation required four climbing mechanisms with different footing to climb steadily along a preset path.

The core component, the Shenzhong Bridge, features two main towers reaching 270 meters in height. Innovative automated rebar welding robots are being used, achieving full-process automation from material feeding to forming and welding. The system addresses issues of low efficiency, poor precision, and high risk associated with traditional methods. The main tower cranes are designed to adapt to different bridge shapes, requiring flexible form-switching capabilities. Lead engineer Tian Wei noted the shift toward industrialization and intelligence to meet the challenges of the Lingdingyang sea area. This technology, developed for projects like the Shenzhen-Zhongshan Link, increases construction efficiency by 60% and reduces on-site personnel by 70%.
