使用超高强度、韧性和自密实解决方案解决最具挑战性的结构方面和耐久性方面的难题。无论是预制还是现浇的,都能满足最苛刻、复杂的要求。

 

Ductal®基础设施解决方案专为从根本上提高新结构和现有结构的性能而设计。

Ductal®基础设施解决方案在抗压、抗拉和抗折强度方面具有卓越性能,再加上高耐磨性、裂缝控制和高抗渗性,使其成为加固、保护结构以及实现结构防水的完美选择,在延长结构使用寿命的同时还能降低维护成本。

1.产品介绍

 

该材料具有高机械性能和卓越延展性,可以建造轻型但耐久的预制桥梁,加固桥面和修复垂直结构,显示出最佳的创新技术和耐久性,且具备提升美观程度的无限可能性。

Ductal®具有很大的预制潜力,可以适应不同规模的项目,缩小结构连接件和钢筋细节的尺寸,降低其复杂性。即使在现有的传统混凝土结构方案中,也能更好地发挥其机械阻力。

2.优化

 

无论是现浇还是预制,Ductal®的抗弯和耐久性优势为修复项目提供了巨大的探索空间,为延长桥梁、桥墩、大梁和接缝等结构的使用寿命提供了可靠、耐用的解决方案。

其高流动性以及自密实的特性使其成为在拥挤区域进行浇铸,且不需要震动的理想选择。此外,其可在短时间内达到典型的设计强度。

凭借其固有强度,可创造更薄的结构件,而且几乎可以实现任何可以想象到的新形状或几何尺寸。

3.实施

 

由于这种形式和功能的结合,Ductal®基础设施满足技术规范的必要要求,同时也为项目提供了具有成本效益的解决方案。

Ductal®超高性能混凝土在力学性能和特性方面都与传统的高强度混凝土明显不同,即使在最恶劣的环境中也能提供长期的耐久性和保护。

Pulaski Skyway

A structure that symbolizes US bridge engineering of the 1930s, the Pulaski Skyway, which links Newark to Jersey City has been partially closed as it undergoes a considerable rehabilitation - the largest in its history. The project was a perfect opportunity for the Federal Highway Administration (FHWA) and the New Jersey Department of Transportation (NJDOT) to take full advantage of the technical benefits offered by Ductal® Infrastructure joint fill over the 5.5km long bridge from Newark Airport to the Holland Tunnel.

 

Mauves sur Loire bridge

The rehabilitation of Mauves-sur-Loire bridge consists in substituting the existing deck (3,500 m²) made of brick vaults with a thin deck made of thin precast UHPFRC slabs. The main objective of the project is to upgrade this historic landmark by increasing its bearing capacity and allowing the addition of cantilevered footbridges.

 

Dominie Creek

Dominie Creek bridge lies on ancestral territory where Caltrans and Tolowa Dee-ni’ Nation worked together to replace the old dilapidated box culvert structure. The finished bridge has an emblem of spawning salmon at each abutment barrier wall which was inspired by the locations salmon and trout spawning.

 

Grafstal road bridge

The concrete of the abutments and central pillars of the Grafstal road bridge (municipality of Lindau) above the A1 motorway showed damage due to chloride infiltration.
