奔赴，向山川大海

雷怡安

虎年的列車呼嘯而來，帶著春意與希望奔赴又一個春夏秋冬。百年未有之大變局，世界發(fā)展大潮洶涌澎湃。中國建設(shè)者心懷敬畏，將家國責(zé)任扛在雙肩，無怨無悔、砥礪前行。

你看！長江盾構(gòu)穿越隧道工程掘進(jìn)里程不斷攀升，山高“隧”長的張懷吉高鐵正式運營，世界跨徑最大、體量最大的跨江風(fēng)雨橋鳳凰嶺大橋通車……一項項重大工程順利落地，一幅幅美好藍(lán)圖變成現(xiàn)實。

“中華民族歷史上經(jīng)歷過很多磨難，但從來沒有被壓垮過，而是愈挫愈勇，不斷在磨難中成長、從磨難中奮起?！敝厥斑@句話，更感受到了中國建設(shè)者們令人嘆服的匠心、決心和毅力。

在又一個四季輪回的春日，讓我們心存敬畏勇敢前行，讓我們滿懷喜悅奔赴山川大海，讓我們懷揣夢想向美好出發(fā)。

As the Year of the Tiger is celebrated by Chinese all over the world， bitter winter days are gradually overtaken by lovely spring days. Though our world is undergoing profound changes unseen in a century， the tide of global development continues to surge forwards with even greater momentum. In face of the situation， Chinas construction industry remains committed to improving peoples wellbeing and strives to fulfill its responsibility for national development.

Its how it renews its commitments. The shield-crossing project that passes through the Yangtze River of the China-Russia Eastern Gas Pipeline is in full swing， the Zhangjiajie-Jishou-Huaihua High-speed Railway that passes through high mountains and a lot of tunnels is put into operation， the worlds longest-span and largest river-crossing “wind-rain bridge” Fenghuangling Bridge is opened to traffic.... As the projects are completed one by one， one after another ambitious blueprint is translated into reality.

“The Chinese nation has experienced many ordeals in its history， but it has never been overwhelmed. Instead， it has become more and more courageous， growing up and rising up from the hardships.” Quoting from a speech delivered by President Xi Jinping at a meeting， the words can speak more volumes about the impressive workmanship， determination， and perseverance of our Chinese constructors.

As the lovely spring comes around， lets embark on the next stage of our beautiful journey with respect， courage， joy， and dreams！

青島地鐵1號線全線開行

2021年12月30日，青島地鐵1號線全線開通，滿載乘客的地鐵列車從山東青島王家港站開出，駛向60公里外的東郭莊站。

地鐵建設(shè)期間，包括中鐵十八局在內(nèi)的參建單位組合了世界上最先進(jìn)的地質(zhì)探測和預(yù)報手段，通過系統(tǒng)性的對比和分析，消除漏判和誤判，實現(xiàn)風(fēng)險的精準(zhǔn)預(yù)判和辨識。作為青島地鐵首條開工建設(shè)的線路，自1992年動工起至今30年的時間，1號線見證了青島這座城市的蛻變。

On December 30， 2021， a metro train full of passengers departed from Wangjiagang Station and headed to Dongguozhuang Station 60km away in Qingdao City， Shandong Province， marking that Qingdao Metro Line 1 was opened to traffic.

To build the metro line， China Railway 18th Bureau Group Co.， Ltd. among other constructors has leveraged a variety of state-of-the-art geological prospecting and predicting methods to avoid errors of omission and fault and realize accurate risk prediction and recognition through systematic comparison and analysis. As the first line to start construction in Qingdao， Metro Line 1 has witnessed how the city has gotten to where it is today since 1992.

“云端高鐵”—— 張吉懷高鐵

2021年12月6日早上7：50，連接湖南張家界、吉首、懷化的張吉懷高鐵首趟列車從張家界西站發(fā)出，正式開通運營。張吉懷高鐵結(jié)束了湖南湘西土家族苗族自治州不通高鐵的歷史，積極融入全國高鐵網(wǎng)，對促進(jìn)中國中西部區(qū)域發(fā)展具有重要意義。

張吉懷高鐵沿線的橋梁和隧道達(dá)到280個，橋隧占全程的比例高達(dá)90%，平地上的線路不到10%。全線的車站、隧道和橋梁基本都建在大山間、懸崖邊，也被稱為“云端高鐵”。線路建設(shè)克服了地質(zhì)條件復(fù)雜、山區(qū)氣候多變等一系列困難，中國鐵路建設(shè)者用先進(jìn)的技術(shù)順利完成了任務(wù)。

At 7：50 a.m. on December 6， 2021， the first train connecting Hunan Provinces Zhangjiajie City， Jishou City， and Huaihua City departed from Zhangjiajie West Railway Station， marking the official operation of the Zhangjiajie-Jishou-Huaihua High-speed Railway. As the first high-speed railway in the history of Xiangxi Tujia and Miao Autonomous Prefecture， it is of great significance for highlighting the role of Hunan Province in Chinas high-speed railway network and promoting the development of central and western China.

Its worth noting that there are 280 bridges and tunnels along the railway， which means that it passes through more than 90 percent of bridges and tunnels and less than 10 percent of the flat terrain. Meanwhile， the stations， tunnels， and bridges are mostly built through mountains or by cliffs， hence the nickname of “a railway built among clouds”. Needless to say， building such a railway must overcome a host of difficulties such as complicated geography and volatile mountain climate. By leveraging advanced technologies， the Chinese railway constructors have completed all the challenging tasks.

世界之最鳳凰嶺大橋

2021年12月30日，廣西柳州第22座大橋鳳凰嶺大橋通車。作為世界上跨徑最大、體量最大的跨江風(fēng)雨橋，主梁跨徑700米，共有5座風(fēng)雨亭，分別為八角亭、六角亭、歇山亭三種樣式。工程主線全長1.57千米，包含西岸主線引橋160米、跨江主橋700米、東岸引橋60米。

On December 30， 2021， Fenghuangling Bridge， the 22nd bridge in Liuzhou City， Guangxi Zhuang Autonomous Region， was opened to traffic. With a span of 700m for the main beam， it is the worlds longest-span and largest river-crossing “wind-rain bridge”. On it， there are five “wind-rain pavilions” that are built in the three forms of octagonal pavilion， hexagonal pavilion， and pavilion with a gable and hip roof. In total， the main line of the project is 1.57km long， including 160m of the bridge approach on the west bank， 700m of the river-crossing main bridge， and 60m of the bridge approach on the east bank.

In addition， the project has obtained more than 20 patent technologies and technological achievements， and won the awards such as “Construction Site with Standardized Safety Control of Guangxi Zhuang Autonomous Region in 2021” and “Gold Award of Iron Structure of Guangxi Zhuang Autonomous Region in 2021”.

南下新通道遵余高速

2021年7月1日，由中鐵廣州局等單位建設(shè)的貴州遵（義）余（慶）高速公路正式通車。該高速起于余慶縣，途經(jīng)湄潭縣、甕安縣、遵義播州區(qū)，接入蘭海高速貴遵復(fù)線冷水坪樞紐，全長約93公里。

通車后，從余慶到遵義的車程由原來的3個小時壓縮至70分鐘。黔北地區(qū)到黔南、黔中、黔東南地區(qū)均壓縮一半以上時間。遵余高速開辟了遵義市南下珠三角新的高速公路通道，是開發(fā)黔北、黔東南旅游區(qū)，促進(jìn)貴州旅游業(yè)快速發(fā)展的重要通道。同時，其為余慶緊貼黔中、立足遵義、面向成渝，一路向北，融入貴陽、遵義都市圈核心區(qū)，融入成渝地區(qū)雙城經(jīng)濟(jì)圈奠定了堅實的交通基礎(chǔ)。

On July 1， 2021， Zunyi-Yuqing Expressway constructed by China Railway Guangzhou Engineering Group Co.， Ltd. （CRECGZ） and other companies was opened to traffic. With a total length of about 93km， it starts at Yuqing County， runs past Meitan County， Wengan County， and Zunyi Citys Bozhou District， and is connected with the Lengshuiping Interchange Hub of Guiyang-Zunyi section of Lanzhou–Haikou Expressway.

After completion， it can cut the travel time between Yuqing County and Zunyi City to 70 minutes from three hours， and at least halve the travel time between northern Guizhou and southern， central， and southeastern Guizhou. Zunyi-Yuqing Expressway represents a new southward expressway route connecting Zunyi City with the Pearl River Delta， and a key channel that facilitates the development of tourist areas in northern and southeastern Guizhou in an effort to boost Guizhous tourism. Meanwhile， it can lay a solid transportation foundation for Yuqing， a county located in central Guizhous Zunyi City with a focus on Chengdu and Chongqing， to become part of the core zone of Guiyang and Zunyi metropolitan area and play a role in the development of Chengdu-Chongqing economic circle.

大連地鐵5號線順利封頂

2022年1月，歷經(jīng)7個月的攻堅奮戰(zhàn)，隨著最后一車混凝土順利澆筑完成，大連地鐵5號線甘井子站主體結(jié)構(gòu)順利封頂。甘井子站為大連地鐵5號線由南向北的第12座車站，主體結(jié)構(gòu)為地下兩層島式車站，標(biāo)準(zhǔn)段為地下兩層單柱雙跨（部分段雙柱三跨）箱形框架結(jié)構(gòu)，車站全長204.3m，標(biāo)準(zhǔn)斷面寬19.7m。

甘井子站主體結(jié)構(gòu)的順利封頂，刷新了大連地鐵5號線主體結(jié)構(gòu)施工進(jìn)度的新紀(jì)錄，為車站附屬結(jié)構(gòu)工程施工和站后機電設(shè)備安裝及裝修施工提供了有利條件。

In January 2022， the main structure of Ganjingzi Station of Dalian Metro Line 5 was completed after seven months of hard work as the last carload of concrete was used. Ganjingzi Station is the twelfth station of Dalian Metro Line 5 from south to north with a total length of 204.3m and a standard section width of 19.7m. Its main structure is a two-level underground island platform， and the standard section is a box-like， two-level underground structure with a single pole and double spans （double poles and three spans in some sections）.

The main structure of Ganjingzi Station was completed with a construction time that is shorter than any other main structure construction projects of Dalian Metro Line 5. This has prepared the way for Ganjingzi Station to advance the project construction of supporting structures and the subsequent installation and decoration of electromechanical equipment.

長江盾構(gòu)穿越隧道快速掘進(jìn)

2022年春節(jié)，距上海市中心100公里的長江江面下，承建中俄東線天然氣管道長江盾構(gòu)穿越工程的中鐵隧道集團(tuán)86名員工依然堅守崗位，確保工程穩(wěn)步推進(jìn)。

中俄東線天然氣管道工程在中國境內(nèi)長5111公里，北起黑龍江黑河，途經(jīng)吉林長嶺、河北永清，南至上海白鶴，分北、中、南三段建設(shè)。經(jīng)過6年的建設(shè)，目前北段和中段已經(jīng)供氣。南段仍在施工中，隧道越江是南段的咽喉。

Though it was the 2022 Spring Festival holiday， 86 workers from China Railway Tunnel Group， a constructor of the shield-crossing project that passes through the Yangtze River of the China-Russia Eastern Gas Pipeline， still stuck to their posts at the construction site under the Yangtze River that is 100km away from Shanghais downtown to ensure the steady progress in project construction.

China-Russia Eastern Gas Pipeline project， with the northern， middle and southern sections built in phases， has a total length of 5，111km in China， starting at Heihe City， Heilongjiang Province in the north， passing through Changling County in Jilin Province and Yongqing County in Hebei Province， and ending in Baihe Town， Shanghai in the south. After six years of construction， the northern and middle sections have gone into operation. The southern section in which the shield-crossing project that passes through the Yangtze River plays a strategically important role is under construction.
