El Aeropuerto Internacional de Chennai es el principal aeropuerto que sirve a la ciudad sureña de Chennai en India. El aeropuerto, situado al sur de la ciudad, es el cuarto aeropuerto más transitado de la India.

Dextra ha estado involucrado en la construcción relacionada con los esfuerzos de renovación del aeropuerto, que tuvieron lugar entre 2008 y 2012.

Para el aeropuerto de Chennai, Dextra entregó su popular solución de acoplador de barras de refuerzo Bartec, que es la principal solución de acoplador de barras de refuerzo utilizada en grandes proyectos en la India.

El contratista principal de este proyecto fue Herve Pomerleau International (HPI) – Consolidated Construction Consortium Limited. El contratista eligió la solución de Bartec para empalmar el refuerzo en todas las columnas y pilares (conexiones verticales), así como para las vigas y losas de cimentación.

Gracias a su tecnología de rosca paralela y barras de refuerzo preparadas con varias longitudes de rosca, Bartec ofrece un nivel muy alto de rendimiento al tiempo que requiere solo un acoplador para aplicaciones estándar (cuando una barra se puede girar dentro del acoplador) y aplicaciones posicionales (cuando no se puede girar ninguna barra). ).

Mae Fah Luang Chiang Rai Airport, located in Chiang Rai, Thailand, is a vital transportation hub for the region. The airport serves as a gateway to the popular tourist destinations of Chiang Mai, Chiang Rai, and the Golden Triangle. In recent years, the airport has undergone a major renovation and expansion project to modernize its facilities and increase its capacity. As part of this project, Dextra supplied over 180 tons of dowel bars to be used as construction joints for the airport runway pavement.

The construction of a runway pavement requires a significant amount of planning and preparation. One of the essential components of a runway pavement is the construction joint, which connects the individual concrete slabs together. Construction joints are necessary to ensure that the pavement can withstand the heavy loads of aircraft and the extreme weather conditions. Without proper construction joints, the pavement can experience cracking, spalling, and other types of damage.

Dowel bars are a critical component of construction joints, as they provide load transfer between the individual concrete slabs. Dowel bars are typically made of steel and are placed in the pavement perpendicular to the construction joint. They allow for movement between the concrete slabs while providing support and load transfer.

For the Mae Fah Luang Chiang Rai Airport project, Dextra supplied over 35,000 dowel bars, totaling more than 180 tons of steel. The dowel bars were manufactured at Dextra’s facility in Thailand and were delivered to the construction site in stages to meet the project’s timeline.

The project has not only increased the airport’s capacity but also provided a safer and more reliable transportation hub for the region.
