نفق قوانغدونغ : أغرب و أجمل و أطول نفق تحت المــاء

انتهت الصين اليوم من أعمال بناء أول وأطول نفق للسكك الحديدية تحت الماء فى


الصين؛ مما يسمح بتشغيل القطارات عبره تحت الماء بأعلى سرعة على مستوى العالم.

ويقع نفق شيتسييانج عبر رافد نهر اللؤلؤ بمقاطعة قوانغدونغ جنوبى الصين، ويبلغ


طوله 8ر10 كيلومتر؛ مما يجعله أطول نفق تحت الماء فى الصين، وقد صمم


للقطارات التى تسير بمعدل سرعه يبلغ 350 كيلو متر/ ساعة وهو أعلى معدل للسرعة للأنفاق تحت الماء فى العالم.

وكانت الصين قد بدأت تشييد هذا النفق فى نوفمبر 2007 ، ويعد جزءا رئيسيا من خط


حديدى سريع طوله 140 كيلو مترا ينطلق من مدينة قوانغتشو عاصمة مقاطعة


قوانغدونغ المركز الاقتصادى الهام فى الصين مرورا بمدينة شنتشن التى تقع فى


المقاطعة ذاتها وصولا إلى هونج كونج.

ومن المقرر أن يتم تشغيل هذا الطريق السريع بين المدن الثلاث فى عام 2012؛ مما


سيقلل من زمن الرحلة بين قوانغتشو وهونج كونج من ساعتين حاليا إلى 40


دقيقة فقط، وفى مرحلة لاحقة سوف يتم ربط هذا الطريق السريع بشبكة سكك


الحديد السريعة بالبلاد، ما سيقلل من زمن الرحلة بين هونج كونج والعاصمة


الصينية بكين إلى 8 ساعات فقط.

لوكان نصيب ما نخرجش من هذا النفق
لكن احنا هنا كذلك في نفق
لكن مظلم .... لا ألوان فيهtears
المهم أشكرك أختي على الصور والمعلومات الطيبة
