In its December 2018 issue, Engineering News-Record Magazine published a very interesting article on engineering techniques put in place for the construction of the new Champlain Bridge.<\/p>\n

Following is an excerpt from this article (the full version is available here<\/a>):<\/p>\n

“When Quebec-based AGF Access Group got the contract to provide access on the bridge, the first thing it did was talk to its special projects division. The company pledged to supply 85% of the access equipment for the bridge project, including mast climbers for the towers, traditional swing-stage scaffolding and ring-tied stairs, as well as temporary and permanent elevators inside and outside the bridge’s pylon. In addition to standard access gear, AGF also saw a particular engineering challenge in accessing the undersides of the cantilevered spans.”<\/p>\n

“They were building the bridge on a cantilevered segmented approach—bridge sections assembled and mounted on a cantilever<\/em>,” says Alex Di Domenico, vice president for major projects at AGF. “We came up with some custom bolting platforms for that.<\/em>” AGF provided three traveling aluminum access platforms instead of the typical steel platforms used in the industry, which features fully electrical controls to travel along the cantilevered sections of the bridge.<\/p>\n

The traveling platforms were a crucial staging area for construction, together providing full coverage of the bridge’s 55-m width. The 19-m-wide platforms, designed to retract to 16 meters when stored at the ends of the bridge, boast a 4,000-kilogram capacity when fully extended. “That was the idea—one tonne for personnel, three for materials,<\/em>” says Sony Trudel, engineering director for special projects at AGF. “When you have all three platforms together, you have [a working area] almost the size of an ice hockey rink.<\/em>”<\/p>\n

Desafío de acceso<\/strong><\/h2>\n

En su edición del mes de diciembre de 2018, la revista “Engineering News-Record” publicó un artículo muy interesante sobre las técnicas de ingeniería implementadas para la construcción del nuevo Puente Champlain.<\/p>\n

Le compartimos un fragmento:<\/p>\n

“Cuando Grupo AGF Accès inc. obtuvo el contrato para proporcionar soluciones de acceso para el puente, su primera etapa fue hablar con su división de proyectos especiales. La empresa se comprometió a proporcionar el 85% del equipo de acceso para el puente, incluyendo plataformas elevadoras para las torres, plataformas móviles y escaleras adjuntas, así como ascensores temporales y permanentes al interior y al exterior del pilar del puente. Además del equipo de acceso estándar, AGF también aceptó un desafío técnico particular para acceder a la parte inferior de los tramos voladizos.”<\/p>\n

“Construyeron el puente con un método segmentado en voladizos; es decir, secciones de puentes ensambladas y montadas sobre un voladizo”, explica Alex Di Domenico, vicepresidente de proyectos de gran envergadura de Grupo AGF Accès. “Creamos plataformas personalizadas para satisfacer esta necesidad.” AGF proporcionó tres plataformas de acceso móviles de aluminio en vez de las plataformas de acero clásicas utilizadas en la industria, cada una dotada de controles completamente eléctricos para recorrer las secciones del puente en voladizos.<\/p>\n

Las plataformas móviles son una zona de tránsito esencial para la construcción y cubren todo el ancho de 55 m del puente. Las plataformas de 19 m de ancho, diseñadas para retraerse a 16 m cuando se guardan en las extremidades del puente, tienen una capacidad de 4000 kg cuando están completamente desplegadas. “La idea era una tonelada para el personal y tres para el material”, explica Sony Trudel, Director de Investigación y Desarrollo y Proyectos Especiales de Hydro-Mobile. “Cuando se ponen las tres plataformas juntas, se obtiene [una zona de trabajo] de casi el tamaño de una pista de hockey.”<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
