Chengdu-Dujiangyan Railway starts from Chengdu North Station, west to Anjing (Pixian) Station on the west ring road of the railway, extends along the direction of Chengguan Highway of National Highway 3 17, and ends in Qingchengshan Town, Dujiangyan City, where it is transferred to Metro Line 2 at Xipu Station. The preliminary planning sites are Anjing, Jinniu, Xipu, Hong Guang, Pixian East, Pixian West, Ande, Chongyi (reserved), Juyuan, Dujiangyan and Zhongxing (reserved), and finally reach Qingchengshan Town. Chengdu-Guangzhou express railway started in May, 2008, and started construction on June 4th, 20165438+1October 26th, 2000. The whole track is paved. On 20th1March 10, the joint debugging and testing of the whole line began; On April 1 day, the trial operation of the whole line began; It was officially opened for operation on May 1 day. Among them, a branch line will be built in Dujiangyan, which is divided into Yingbin Road Station, Libing Square Station and Lidui Park Station. Because the lines pass through the ground, all three stations are underground platforms, which makes Dujiangyan the first county-level city in China connected with the subway. At present, due to various reasons (mainly urban demolition compensation, etc. ), the specific completion time of the branch line from Dujiangyan to Dujiangyan Scenic Area is unknown. You can see that the underground tunnels in Yingbin Square are under construction, and most of them take the subway line. On April 1 day, Chengdu-Guangzhou express railway was completed and put into trial operation. After the "5 1 2" Wenchuan earthquake, the Chengdu-Guangzhou express railway, the first large-scale infrastructure reconstruction project signed by the Ministry of Railways and our province, will be completed and put into operation on May1this year. On New Year's Eve, the Chengdu-Guanzhou Railway is laying tracks all over the line. Express rail voiceover-"You can go home for the New Year this year!" With the completion of the Chengdu-Guanzhou express railway, the builders who have been busy for more than a year can finally breathe a sigh of relief. "Everyone can go home for a reunion year this year!" Li, secretary of the Chengdu-Dujiangyan Railway Project Department of China Railway Eighth Bureau, said with emotion. In the past year, the construction site of Chengdu-Guangzhou high-speed railway was tense and busy. During the peak period of Chengdu-Dujiangyan Railway Project Department of China Railway Eighth Bureau, 1500 workers worked at the same time. The sweating scene was spectacular, and everyone sacrificed the opportunity to reunite with their families. Last Spring Festival, the workers were on the construction site, but this year, with the rapid railway construction drawing to a close, the workers will continue to return home. Express rail and convenience-taking the express rail is as convenient as taking a bus. As the first new railway line project that started construction after the disaster, filling the express railway is not only conducive to revitalizing the tourism industry and improving the quality of life and residence, but also the first high-grade railway in southwest China, which has exemplary significance for changing the backward status quo of southwest railways and speeding up railway modernization. After the opening of the 30-minute life circle irrigation through train, passengers can reach Dujiangyan in half an hour from Chengdu. Feel the prosperity of Chengdu during the day and enjoy the tranquility of Qingcheng Mountain at night. The "white+black" lifestyle popular in developed countries in Europe and America will be realized by ordinary citizens. The first phase of Chengdu-Guangzhou express railway will set up six stations in Dujiangyan, among which Yingbin Road Station, Libing Square Station and Lidui Park Station will be underground platforms. In other words, the "Express Rail" became a "subway" after it arrived in Dujiangyan City. In this way, Dujiangyan will become the first county-level city in China to connect with the subway. After the passenger flow goes up, the train will replenish it in time. By then, the minimum tracking interval between trains can reach 3 minutes. " Zhou Lixin, deputy general manager of Chengdu Railway Co., Ltd. and chief engineer of Chengdu-Dujiangyan Railway Project, said that all trains of Chengdu-Guangzhou Express Railway are EMU, and 8 trains were put into operation initially. According to the planning and design of urban railway and the requirements of serving urban public transportation, the operation will be "public transportation" and the bus credit card system may be introduced. By then, the bus card can also be swiped on the express train, and the fare will definitely be lower than the highway passenger fare. There are 9 new bridges/kloc-0 on Chengdu-Dujiangyan high-speed railway, with a bridge-tunnel ratio of 67%. Ballastless track is adopted in the whole line, which is the first application of this advanced technology in the central and western regions. According to the relevant person in charge of China Railway Second Bureau, except Dujiangyan to Qingchengshan Town, Chengdu to Pixian and Pixian to Dujiangyan all adopt viaducts with a length of more than 40 kilometers. If the rapid passenger flow flies in the air, it will make people feel like walking on clouds. At the same time, when designing the viaduct, the overall landscape was specially designed to facilitate passengers to better appreciate the landscape along the railway. Linking to the whole country, the completed Chengdu-Irrigation Railway will also link to the whole country-for the tourism needs of Mianyang, Leshan and Chongqing, the railway will run cross-line trains in Chongqing, Mianyang, Guangyuan, Leshan and Wanzhou. The tourist bus in Beijing can go directly to Qingcheng Mountain, and there is no need to change trains in Chengdu. In 2020, Mianyang can run two pairs of trains every day, Chongqing three pairs, and Mianyang can run three pairs all day in 2030. The status of regional transportation hub is thus revealed. Mr. Yang Jianying, chief consultant of Chengdu Urban Development Strategy Expert Group, said that Chengdu-Guanzhou Express Railway has four stations in Dujiangyan area, which are usually called "Four Golden Flowers", namely: Chongyi, Juyuan, Zhongxing and Qingcheng Mountain. These future railway towns will form a perfect "railway economic belt" to fill the railway express line. Chongyi Town's "Chongyi Gate" supports the "first stop" and Chongyi Town is the east gate of Dujiangyan. Because of its strategic location, it connects Chengdu at the bottom and Xuankou and Songpan at the top, becoming a famous West Road Station, which is called "the first stop of Tianfu". Chongyi is known as the "hometown of steel doors and windows". "After the completion of the Chengdu-Guanxi Railway, Chongyimen will definitely go further". Juyuan Town is the "gathering place" of ideology and culture, and the next node of Chongyi Town is Juyuan. Surrounded by two rivers, it is 8 kilometers away from Chongyi and 8 kilometers away from Dujiangyan. Juyuan is characterized by "not entering the mountain near the mountain and not entering the weir near the water". Because of the natural landscape and water conditions, it has always had a good living environment. There is the site of Xiang Ying Temple, one of the famous "Four Jungles" in western Sichuan, which was built in the Tang Dynasty, and there is Luofeichi which covers an area of 1 mu nearby. Now there are two famous painter villages and sculpture villages. Zhongxing Town, the largest healthy residential area in the future, is the central node of Qingcheng Mountain, a Taoist holy place, and Dujiangyan Irrigation District, a tourist holy place. Enjoy the prosperity and modernity of Dujiangyan and the natural and cultural edification of Qingcheng Mountain. Under the influence of these two cultural backgrounds and economic environment, a unique life circle has been formed. "So this place should form a good healthy residential area," Yang Jianying said. Qingchengshan Town is a new "smart town". "Qingcheng Mountain is the intersection of Taoist culture and Qingcheng's humanistic and natural heritage." Yang Jianying said that it is actually a strong terminal benefit for the Chengdu-Guanzhou high-speed railway to choose this place as the terminal. According to the new plan, Qingcheng Mountain will become a "smart town". In addition to tourism, it will also form a new software industry base integrating information technology education, industry and support services. Sketch of fast track-the average distance between stations of the whole line 14 is less than 5km. The expressway line is 66 kilometers long and the viaduct is 42.6 kilometers long, accounting for more than 70% of the whole line. Preliminary planning 14 Main stations: Chengdu North Station, Anjing Station, Jinniu Station, Xipu Station, Hong Guang Station, Pixian East Station, Pixian West Station, Ande Station, Chongyi (reserved), Juyuan Station, Dujiangyan Station, Zhongxing (reserved) and qingchengshan railway station. All newly-built lines adopt ballastless track and jointless track, and the target speed from Pixian to Qingchengshan is 200 km/h. Eight trains will be put into operation in the initial stage, and the minimum interval between trains can reach 3 minutes after the passenger flow is sufficient. For the convenience of passengers, the average distance between stations of Chengguan Express Railway is less than 5km, the shortest distance is 2km, and the distance from Hongguang to Pixian West is10km. There are four stations in total. The railway is fast-it takes less than half a year from being put on the agenda to starting work. In May 2008, the irrigation express railway started construction, and was completed and opened to traffic in May 201/kloc-0. Such a speed is very rare in the history of railway construction. Why so soon? "It is very important because we have a plan, because it is already in the planning of' three tracks and nine roads'." On July 22, 2009, Li, member of the Standing Committee of Sichuan Provincial Party Committee and secretary of Chengdu Municipal Party Committee, gave the answer in one sentence. "The route planning began in 2007, and the preliminary preparation saved at least 1 year preparation time for the irrigation express railway." "I have never seen a railway project that was established so quickly and started so quickly." Liu Qingsong, chief engineer of Chengdu-Dujiangyan Railway Project Management Department of China Railway Second Bureau, said that during his 20-year working career, Chengdu-Guangzhou express railway has created many firsts. The west artery of the express railway-shortening the distance between time and space to realize the whole Chengdu. In May next year, the completion of the Chengdu-Guangzhou express railway will make Chengdu, Pixian and Dujiangyan infinitely connected. Without the concept of city, it will take the lead in realizing the concept of "Chengdu in the whole region" in the west of Chengdu, and the Chengdu-Guanzhou Express Railway will also become the "western artery" to "move" the whole region of Chengdu. 10 6 17, the main venue of the west Expo, the whole pixian county was full of pride-after the influx of 22 billion funds in the year, pixian county signed another1300 million big order at the west Expo. High-speed rail has at least 20% credit. In Dujiangyan, "it's not far to say, it's not close!" The traffic from Chengdu to Dujiangyan and Qingcheng Mountain has been very embarrassing. Although there are roads such as Chengdu-Guancheng Expressway and Chengqing Expressway, "distance is not distance, but time". The arrival of high-speed rail will change all this. Xipu will become the intersection of Chengdu-Dongguan Express Rail and Chengdu Metro Line 2, and realize "zero transfer" between the subway and express rail on the same platform. It takes only 15 minutes from Pixian to Chengdu, and only 30 minutes from Dujiangyan to Chengdu. Beautiful as a work of art, Chengdu in June 2009 was foggy. The high-speed rail viaduct extending from Chengdu to Dujiangyan penetrates the fog with no end in sight. At this time, it is more like a long dragon hovering over Chengdu. At the construction site of Chengdu-Dujiangyan Railway Project Department, cranes, excavators and other large equipment have quietly retreated. What we see in front of us are rows of neat bridges and fast-track stations that are about to be completed, and the Chengdu-Dujiangyan railway has been connected. Humanized Design-Laying Ballastless Track Farewell to "clang" In fact, the construction of Chengguan Express Railway started from June 5438+ 10, 2008. Chengdu-Guanzhou Express Railway passes through the rich hometown of Chengdu Plain, where the population is dense, which determines that the railway should be overhead as far as possible. Among them, in the 28.7-kilometer project from Chengdu North Station to Pixian County undertaken by China Railway Eighth Bureau, there are 3 extra-large bridges with 1 bridge. The longest Pixian viaduct is18km long and the total length of the bridge is 21.77km, which is a record in the history of railway construction. Li, secretary of Chengdu-Dujiangyan Railway Project Department of China Railway Eighth Bureau, took the reporter to the viaduct. He pointed to the ballastless track slab of the viaduct extending infinitely under his feet, and said seriously that the track is waiting to be laid here. "The fast track of spring is coming to people!" Witness: the design of the express train is humanized everywhere-everyone who has been on the train knows that the train will make a "clang, clang" sound during driving. This is actually not the sound made by the train itself, but the sound made by the stress caused by the wheel running over the rail gap. In the future, you can't hear the voice of "disturbing the people" when you take the Wan-Kuai Railway. Li introduced that the whole line of Chengdu-Guanzhou high-speed railway adopts seamless rails, and the 500-meter-long rails are welded into a whole. The track is flat and won't make a "clang". On both sides of the viaduct of Chengdu-Guangzhou express railway, sound absorbing plates and sound barriers are installed all the way, which greatly reduces the noise and can absorb the sound blocked by the sound barriers. It is more convenient to travel-get off the express train and get on the subway Xipu station "zero transfer". The arch shed has been exposed at Xipu station site of Chengdu-Dujiangyan railway. Xipu Station is not only the intersection of Metro Line 2 and Chengguan Railway, but also an important hub station transfer center for traffic along the line. Li said that after the subway runs in the future, people can directly transfer to the subway when they get off the express train, thus realizing "zero transfer" in the true sense. From the Third Ring Road in Chengdu to Pixian County, along the railway station, the Xipu Station under construction is very conspicuous, and the polyhedral space steel frame component built on the viaduct is the canopy of the future station. The platform not only adopts the elevated platform mode, but also adopts the same column-free canopy and grid structure as the national swimming center-Water Cube. This structure welds the polyhedral spatial steel frame members with each node, which perfectly embodies the combination of spatial structure and high-rise structure. The construction area of Xipu Station is about 7005 square meters, the platform width is 15 meters, and the effective platform length is 450 meters. It is also the terminal of the west extension of Metro Line 2, connecting Hong Guang Station in the west and Jinniu Station in the east. There are two floors on the ground. The first floor is equipped with service area, ticket office, office, equipment room, electromechanical room, information room, etc. The elevated second floor is dedicated to riding and waiting. This is how zero transfer is realized-Xipu Station is a two-story platform station, and passengers get on and off the bridge, just like a station suspended in the air. According to the person in charge of the project of the Second Company of China Railway Eighth Bureau, Metro Line 2 will go uphill after coming out of Jinniu Station, and will gradually drill out of the ground, and then drive the viaduct from the ground. When Metro Line 2 arrives at Xipu Station, it will be on the same plane as the Chengguan Express Railway, located on the left and right sides of the platform respectively. In this way, after getting off the subway, passengers board the express train directly on the other side of the platform without changing to the platform, thus realizing zero transfer. Creative design-Viaduct is both a landscape and a work of art. Viaduct is used in two-thirds of the section of Guanzhou-Express Railway, with a total length of 42.6 kilometers. On the Chengdu-Dongguan Railway from Chengdu to Qingcheng Mountain Scenic Area, the viaduct has undoubtedly become a unique scenery on this tourist route. Opaque sound barriers will be set on both sides of the viaduct passing through residential areas, and transparent sound barriers will be set on rural sections to facilitate passengers to enjoy the pastoral scenery. According to the person in charge of China Railway Second Hospital, the whole line is planned as three sections, and Chengdu-Anjing Station will be along the Chengdu hub, with an extra-large viaduct with a length of1.6 km; In the second section of the main line from Pixian to Dujiangyan Station, there are five viaducts in Pixian, Ande, Chongyi, Juyuan and Dujiangyan, of which the length of the viaduct in Pixian section is 21.1km; In addition, a viaduct will be built from Dujiangyan to Lidui Park. Landscape-The pier is shaped like a Roman column. If the viaduct of the express railway looks like a long winding dragon, then the rows of piers are like dragon claws with different shapes, which is a special scenery along the express railway. These piers have different shapes, including Roman pier, π pier and three-column pier. The pier erected at the starting point of Pixian viaduct of Chengdu-Guangzhou express railway is very conspicuous and is a highly creative Roman column pier. This kind of Roman column is not found in the whole line of the express railway, but only in this extra-large bridge section. Pixian viaduct of high-speed railway has 5 spans 10 Roman pier. π-shaped pier is the "king" of piers because of its shape like a symbol of pi. According to reports, ordinary piers use 5 tons of steel bars, which is 10 times that of ordinary piers. Each pier is smooth and exquisite on the ground of irrigation and fast iron products. In order to ensure the beauty of the pier, the application of high-efficiency release agent should be operated by designated personnel. If there is any defect after demoulding, repair it by hand, even if it is not obvious, dip it in white cement and smooth it. Therefore, it is no exaggeration to say that the piers here are works of art. Looking back on April 2009, the beams of Chengdu-Dongguan express railway began to be erected and ready for track laying. In June, the high-speed railway bridge across the ring city, one of the throat projects in Chengdu-Dongguan-expressway, was closed. On July 3rd/KLOC-0, the Dujiangyan Elevated Line of Chengdu-Guangzhou Express Railway crossed Jinma 8 days earlier and arrived 18. At the end of July, the viaduct beam crossing the Chengguan Expressway was successfully closed. 165438+1On October 26th, the last beam of Pixian Extra Large Bridge was successfully erected, marking the completion of the erection of the main bridge of the line. 65438+In late February, the ballastless track of Chengdu-Dongguan high-speed railway viaduct began to be laid. 20 10 look forward to the end of 65438+ 10, and complete the whole track project. Before the end of February, the whole house construction and decoration project was completed. On March 1 day, the Chengdu-Guangzhou express railway completed the joint commissioning and test of the whole line. On April 1 day, Chengdu-Guangzhou express railway was put into trial operation. On May 1 day, Chengdu-Guangzhou express railway was officially put into operation.
