推进墨西哥的交通基础设施

想象一个机场，每年有六个跑道，每年最多可服务1.2亿乘客，距世界上最大的大都市地区之一约25公里。该机场，墨西哥城新国际机场（NAICM），目前是墨西哥最大的基础设施项目，预计将于2020年开放。

米illions of travellers are expected to fly into and out of NAICM, thousands of airport personnel will commute on a day-to-day basis, and hundreds of businesses will reside within or rely on the airport business district. All these airport users depend on transport infrastructure that provides an effective solution.

米exico's Federal Secretariat of Communications and Transport (SCT) has developed a plan in which several international and Mexican companies are responsible for the design and construction of the NAICM. Besides the NAICM, a 57.7 km high-speed, modern, efficient and safe railroad is planned for connecting the city of Toluca and Mexico City.

拥有40年经验的墨西哥土木工程服务公司IUYET联盟IUYET积极参与新的国际机场和铁路的建设。

Responding to global standards

这Interurban train will provide significant transport and economic benefits for the whole Mexico City region, and, along with NAICM, will be an important contributor to Mexico’s economy. This new airport will not only facilitate tourism but also trade, and it will connect widely Mexico City to the rest of the world.

For this project, Consorcio IUYET uses a variety of Leica Geosystems solutions to capture, model and analyse the data, such as total stations, theSiTrack:Onerail maintenance and refurbishment solution, GNSS receivers, digital levels and construction lasers combined with Leica Geosystems measurement software.

As part of the works performed by Consorcio IUYET for this project, 2,800 scans to cover 50 square km were captured and unified in a record time of two months, using the Leica ScanStation P40. The point clouds from these scans were cleaned and registered using theLeica Cyclone9.1 software for the most accurate generation of the Digital Terrain Model (DTM) of the zone. These data were used to develop the land and air design of the NAICM.

Consorcio Iuyet首席执行官Guillermo Ortiz说：“ Leica ScanStation P40使我们能够获取研究区域的3D点云，以生成数字地形模型并创建平面图。”“这使我们能够获得可靠的信息和高精度数据，以开发建筑信息建模（BIM）。”

这railroad line will have four stations and two main terminals, including a station in Metepec, close to Toluca International Airport. The train will have a maximum speed of 160 km/h. The project will also involve the construction of a 3.9 km, 30 m deep tunnel to secure environmentally protected zones; this is the most challenging task. Consorcio IUYET is the first company in North America to acquire the Leica SiTrack:One, the mobile mapping platform made especially for railroad documentation, which will be used for the construction of the high speed passenger train Toluca-Mexico City.

“The SiTrack:One and its integrated P40 ScanStation will be used to obtain a highly accurate 3D point cloud of the railroad environment for applications such as rail geometry calculations, platform gauging and rail clearancing,” said Ortiz. “Rail’s ability to compete with other modes of transport, in particular with road, is crucial for its competitiveness. New technology such as the Leica SiTrack:One can offer much to help modernise railways and develop a smarter and safer rail system that will benefit travellers and commuters.”

Using the most suitable technology

机场旅程体验对旅行者对机场质量的看法产生了很大影响。目的地和机场之间的路线将是墨西哥的第一和最后一个乘客。

铁路项目于2014年7月开始建设，预计新线路将于2018年开放。它将通过15架火车的机队进行操作，提供39分钟的端到端旅行时间。使用允许轻松访问的技术，该项目正在及时完成。

Consorcio Iuyet在该项目的不同阶段结合了几种技术。这无人机系统were used for the photogrammetry and construction inspection while theLeica Viva GS15GNSS天线帮助建立了测量参考网络，而Leica DNA03数字水平确保了高度测定控制。

这flexibility and simplicity in the collection of the measurements allowed Consorcio IUYET to focus efforts on evaluating and analysing data rather than working out how to collect the required information.

Ortiz说：“多亏了Leica Geosystems产品，我们亚搏彩票手机版下载的项目目标是明确，现实，可行的，并且旨在按照计划的高质量标准完成该项目。”

这firm also used theLeica Nova MS50集成3D点云测量值，以促进地形调查数据的收集和可视化以及详细的高精度扫描。确保信息从现场快速传输到完成对这个苛刻的项目至关重要。

Ortiz说：“ Leica Geosystems设备之间的精确性和兼容性可以为我们公司提供最佳利用。”“对准确度量的需求对我们的项目至关重要；它支持精度并节省金钱和时间。我们的客户在我们的工作中认识到的可靠性反映了Leica Geosystems解决方案的质量。”

测量支持创新

米exico City has an opportunity to enhance the development of the airport region, to ensure the airport’s support to the local and national economy is increased.

For a number of reasons, the terrestrial transport is considered to play a significant role in sustainable airport access. An effective and efficient transport network is one of the most important elements to ensure that the airport is cohesively integrated in Mexico City.

“The Mexico City New International Airport and Interurban Toluca-Mexico City train line will be a presentation for Mexican innovation,” said Ortiz. “Known as the 'Airport of the future,' it will be one of the world’s largest airports and will revolutionise airport design.”
