Dandong station

alignments

Dan rapid railway line long 293 kilometers, located 15 sites for passenger traffic line drawn from Dalian North Railway station, the salt across the overpass, the inland port logistics park, drill simultaneously on the Shenyang-Dalian railway cross-Dalian highway, turning to the northeast station in both the Golden state, Golden state in both yards the north side of the front yard of parallel lines, then across existing railway Harbin-Dalian line to form a tunnel through Hongta industrial zone, drill both the Shenyang-Dalian railway, the railway and then continue eastbound across the highway Dan, Dengshahe, too Dengshahe station after discount to the northeast, from the north side by guojiatun, after continued northbound across the river flagpole, Liu River and the existing railway Jincheng, after the parallel existing railway had xingshutun, Dayao jiatun by entering the Jinzhou District Champlain shop area. Then continue north over the railway Dasha, cross Jincheng railway; then through the skin Yang planning area, across the river water. Then the line east to move closer to the existing line of Jincheng, Jincheng across the line, crossed into the territory of the garden Biliuhe port economic zone. Continue to the existing railway line north of the city of Trang parallel forward, the city rebuilt after the village line drill, in both the city line south of the village continue in parallel, the first line into the territory of Zhuanghe City, east Dan high-speed route along the south after the saddle Hill industrial Park North, North chestnuts, Gushan town, in the loess ridge north across the great Southern highway to Dan, the son Kitai, Donggang across State Road 201, then northeast through the same shangxingzhen reach this fold line to the southeast Dandong terminal line station.

the operations of

operator course

2015 Nian 12 17, Dan rapid railway official opening and operation. Dan rapid railway opened early, arrange open daily operations EMU trains 12 pairs, 17 pairs of freight trains CDB. Dandong to Dalian between EMU trains by Intercity-opening the line.

2017 Nian 11 15, former Shenyang Railway Bureau to adjust the part of the train operation diagram, Dan rapid railway multi EMU outage, Dalian Zhuanghe interval plus open four EMU, Dandong to Shenyang D7636 / 41 EMU peak times changed line operation.

Passenger traffic

As of December 17, 2016, Dan rapid railway opened the first anniversary of operation, a total of 4.64 million people to send visitors, average daily send visitors 12,700 people, in 2016 on October 3 the highest single-day passenger sends a record 25,000 passengers.

Equipment Facilities

vehicle facilities

Dan Rapid Railway Lines trains include CRH5 EMU trains, CRH380B EMU trains and "harmony" electric locomotive. Wherein CRH5 EMU neutral Changchun Railway Vehicles Co. production design, the vehicle high-strength, lightweight aluminum drum body section, grouping eight, five three movable trailer, traction power of 5500 kilowatts, the vehicle can be two reconnection to run for long distances, transport demand large capacity, suitable for cold areas.

Runtime

CRH5 EMU straight-computer control electro-pneumatic braking system, may be used to achieve artificial braking, emergency braking; and effectively combined with the signaling system, overspeed safety realize automatic parking guide stop function, ensuring a quick and smooth in any case stop; achieve energy feedback grid, saving energy by an electrical brake; blend braking by air to achieve a large braking force at high speed, effectively reducing brake wear plate and the gate plate.

construction achievements

technical problem

• unique soft subgrade

Dan rapid railway to the north east of Hong Kong Zhuanghe through the western part of the coastal region are mostly alluvial plain, flat open terrain, in most places the distribution of soft soil, characterized by high water content, high void ratio, high compressibility, etc. local soft soil no hard shell, soft soil subgrade total length of 20.59 kilometers, accounting for 7.1% of the total length of the line. After many discussions and tests, soft roadbed using cement mortar in the construction of the piles, concrete piles stirring, various methods CFG pile reinforcement, reinforced concrete pipe piles and the like, including settlement observation point and set a total of 224, to ensure that soft soil roadbed ability to meet the passenger train and truck traffic.

key project

• Ocean River Bridge

From Dandong exit station 73 km, the famous Yalu River coastal wetland national Nature. To maximize avoid damage to the natural environment protected areas, Dan rapid railway built ocean River Bridge to cross the bridge and roadbed form the outermost experimental area protected areas. Bridge construction process, the use of steel cofferdam, ban set to take spoil ground, construction sites in protected areas. At the same time, but also specifically to avoid the migratory bird breeding period and Construction year March 20 to the end of June, setting a flag Jinming, take long rail welding and other noise and vibration reduction measures, both sides of the road through the wetlands sound barrier and to install a variety of ways collision of birds and other facilities, to maximize the protection of the natural environment, reducing the impact on the survival of birds, embodies the concept of harmonious development between man and nature co-exist in symbiosis.

• two shilipu tunnel

two shilipu tunnel located in Dalian City, Liaoning Province about 6 km northeast of Jinzhou District, a total length of 7645 meters, crossing the mountains, valleys and mountains located between low mountains, mountain undulating terrain, one of the key control Dan rapid railway projects. Two shilipu improvements in tunnel construction practices, provided the import, export, and a total of eight three inclined parallel construction excavation surface tissue, and in accordance with the level of the surrounding rock parallel step method embodiment step method and short respectively, cross-flow jobs and overcome the complex geology surrounding rock, broken rock and other difficult to ensure project quality and progress.

Dan Shen Dan rapid railway through the convergence of high-speed railway, the Shenyang-Dalian railway, the formation of a "big triangle" in central and southern Liaoning railway network of the main skeleton, ending Dandong no history between Dalian and direct access to the railway, which greatly improved transportation efficiency and service levels between the two cities of Dalian and Dandong, the promotion of port economy and the rapid development of rail transport, service of the Northeast economy development will play an active role .
