Chennai International Airport is the main airport serving the southern city of Chennai in India. Located to the south of the city, it is the fourth busiest airport in India.

Dextra was involved in the construction efforts surrounding the airport’s renovation, which took place between 2008 and 2012.

For Chennai Airport, Dextra delivered its popular 巴特克 rebar coupler solution, which is the primary rebar coupler used in large projects across India.

The main contractor for this project was Herve Pomerleau International (HPI) – Consolidated Construction Consortium Limited. The contractor chose the Bartec solution to splice 钢筋/增强筋 in all columns and 码头 (vertical connections) as well as for beams and foundation mats.

Thanks to its parallel thread technology and rebar prepared with various thread lengths, Bartec offers a very high level of performance. It requires only one coupler for both standard applications (when one bar can be rotated inside the coupler) and 定位连接 (when no bar can be rotated).

位于泰国清莱的皇太后清莱机场是该地区重要的交通枢纽。作为通往清迈、清莱和金三角等热门旅游胜地的门户，该机场近期进行了大规模的翻新扩建工程，旨在实现设施现代化并提升运力。作为该项目的一部分，Dextra 为机场提供了超过 180 吨的 岩栓 建筑用钢筋 接头 在机场跑道路面上。

跑道路面的施工需要精心规划和准备。跑道路面的一个重要组成部分是施工缝，它连接着各个混凝土板。这些 接头 确保路面能够承受飞机的重载和极端天气条件是必要的。如果没有适当的施工 接头，路面可能会出现开裂、剥落和其他类型的损坏。

岩栓 钢筋是建筑的重要组成部分 接头因为它们有助于在各个混凝土板之间传递荷载。通常由钢制成， 岩栓 钢筋垂直于施工缝放置，允许混凝土板之间移动，同时提供支撑并实现有效的负载传递。

对于清莱皇太后机场项目，Dextra 提供了超过 35,000 岩栓 钢筋，总计超过180吨钢材。 岩栓 钢筋在 Dextra 位于泰国的工厂生产，并分阶段运送到施工现场，以满足项目的时间表。

该项目的顺利完成，不仅增加了机场的容量，而且提高了机场的安全性和可靠性，为该地区提供了更高效的交通枢纽。
