Cantilever bridge building machine

The applicable scenarios of the cantilever intelligent bridge building machine include: 1) Cross line complex terrain construction ① Crossing traffic arteries Suitable for continuous beam construction of high-speed railways crossing existing national highways, expressways, or railways, such as the Shenjiang Railway crossing the 105 National Highway Shaxi Extra Large Bridge. The high-altitude pouring is accurately completed by a cantilever intelligent bridge building machine to avoid interference with ground traffic. ② Canyon and River Region In complex terrains such as canyons and rivers, smart bridge building machines can achieve unsupported construction, reducing reliance on foundation stability through modular sliding and digital control. 2) Large span continuous beam engineering ① Large span bridges over 72 meters For large-span structures such as 72 meter+135 meter+72 meter continuous beams, the intelligent bridge building machine shortens the critical line construction period by 60 days through modular design, while improving overall stability by 30%. ② Curve Bridge Adaptation Support the construction of continuous beams in straight or curved lines, and adapt to different cross-sectional designs through automatic widening technology of internal formwork, resulting in a comprehensive efficiency improvement of over 20%. 3) Urban and traffic intensive areas ① Urban elevated bridges In urban elevated or comprehensive hub projects, smart bridge building machines adopt enclosed operations to reduce noise pollution, and use hydraulic positioning systems to accurately control construction accuracy, reducing the impact on surrounding buildings. ② Work in nearby residential areas Equipped with fully enclosed dust prevention devices and intelligent monitoring systems to ensure construction safety and reduce dust dispersion, suitable for sensitive areas adjacent to residential areas. 4) Intelligent construction and environmental protection requirements ① 3D printing bridge construction Using 3D printing technology to pour concrete layer by layer, achieving rapid prototyping of complex shaped bridges, while improving the welding quality and structural reliability of box girders. ② Material and energy consumption optimization By optimizing the amount of concrete and steel loss through intelligent algorithms, material loss during construction has been reduced by 15%, which meets the requirements of green construction. 5) Special structure adaptation ① Multi directional load node construction Suitable for irregular connection nodes of high-speed rail, subway, and highway transfer hubs, precise shaping of multi-directional load transfer structures is achieved through digital modeling. ② Seismic zone bridge reinforcement Combining prestressing technology to enhance the seismic performance of bridges, suitable for high-speed railway bridge engineering in earthquake prone areas. Note: In practical applications, process parameters need to be selected based on bridge span, alignment, and environmental limitations. For example, bridges with smaller curve radii should prioritize the use of internal model automatic adjustment technology, while cross traffic mainline projects need to strengthen closed protection measures.
