Among the many high -speed rail lines across the country, although the length of the Jilai high -speed rail is not long, it can be called the "encyclopedia" of my country's high -speed rail construction. Jilai high -speed rail bridge has multiple tunnels, and the line crosses various complex geology such as sedimentary rocks and rock -soluble. It crosses many railway trunk lines such as Jiqing, Shiji, Jiaoji, and Wathei, and highway, national provinces, and national provinces. China Railway's participating units are carefully organized and scientifically constructed, and the use of digital, information technology and advanced and mature process methods to build bridges, rails, station buildings, and four electricity projects.

Ingenious design, boutique creation

The high -speed rail station house on the entire line is stunning appearance

There are 6 stations at the Jilai high -speed rail. Except for Jinan East Station as existing stations, 5 stations such as Licheng Station, Zhangqiu South Station, Xueye Station, Laiwu North Station, and Steel City Station are newly built. The hospital is responsible for design.

During the design process of the China Railway Second Court, in the design of the Jilai high -speed railway station, taking "one stop, one scenic spot, station is a boutique" as the work goal, Licheng Station actively created a comprehensive concept of TOD, uniformly planned the plots around the high -speed rail, reserved the subway to reserve the subway The connection port, rational use of the space under the bridge to do commercial development, intensive land and other innovation points; Xueye Station is located in the famous Xueye Lake Scenic Area. The design combines the terrain to actively improve the level of the station building and solve the problem of limited municipal functions of the narrow venue. Before the station The integrated design of the square and the mountain park to create a landscape park -style high -speed rail station.

At the same time, the design team focuses on combining the local cultural characteristics, incorporating different elements into the building itself, and creating different styles of high -speed railway stations. Among them, the Steel City Station Station is located in the steel city area. It is an important Lai Steel production base. The 6 giant pillars of the building facade show the beauty of steel and steel. Culture; the base of the station building of Laiwu North Station adopts a thick physical colonnade, which symbolizes the shape of the Great Wall wall stack, solemn and elegant. The long history and culture of the Yuanqiu station shall be used to draw on the lines of the top lines of Zhangqiu Xingguo Temple Temple Temple.

Licheng Station in construction

Licheng Station is the largest station across the Jilai High -speed Railway, which is undertaken by China Railway Tenth Bureau. The station adopts a bridge construction separation structure. There are two out -of -site station halls across the line, which belongs to the offline station room (the waiting hall is set under the rail area), which is the first bridge -type high -speed railway station room in Shandong Province. As a large -scale railway station building comprehensive project with an integrated bridge construction, the structure system of the Licheng Station station building is complex, the construction site is small, the multi -professional cross construction, and the construction organization is difficult, and the construction period is only one year. The task is heavy and the construction period is urgent. The project department has formed the industry -university -research team to use digital construction technologies such as "BIM+Smart Site" to achieve the intelligence of management behavior, and realize the dynamic visibility, controlling, and controllable construction site. Promote steadily.

Cooperation, Ke difficulties to attack

Lower "hard bone"

Cross -Jiaoji Railway Bridge and the cross -Jiqing High -speed Railway Bridge are controlled by the heavy difficulty of the Jilai high -speed rail. Bridge, a train passed every 10 minutes, and prefabricated at 20 meters above the business line. The construction distance was only 5 meters recently, and the safety pressure was huge. The builders of China Railway Tenth Bureau have overcome the effects of different weather, wind speed, temperature on the weight and stress of the rotor, and achieve a safe and precise transfer of the busy railway trunk line. Cross -Jiqing high -speed rail turn bridge

The Zhaishan Tunnel is located in Licheng District and Zhangqiu District of Jinan City. The total length is 4812 meters. The dual -line tunnel is the longest tunnel on the entire line of Jile high -speed rail. China Railway Second Hospital and the construction unit sincerely cooperate, give full play to the technical expertise of the design unit, provide strong technical guarantees, and successfully overcome the impact of tunnel rock -soluble, dangerous rock drops, and biased pressure. The Northeast Ridge Tunnel undertaken by China Railway Third Bureau was 3712 meters in length. During the excavation process, it crossed the ancient Grain Grain contact belt many times. On the basis of making full use of advanced geological forecasting technology, the technicians of China Railway Second Court combined with deepening gun holes, surveillance measurement, and palm -sidelines, comprehensively predicting the geological situation in front of them, and accurately predicted the mashing water that may exist in front of them, and The outer rock mutation and other positions and scale overcome the risks of shallow burial, repeated crossing contact bands, and swelling mud, and ensure the smooth penetration of the tunnel.

Multiple measures, grab the progress

Refresh "China Speed"

China Railway Fourth Bureau is mainly responsible for the launch of the long -rail launch of the Jile high -speed rail, road fork laying, and rail panel laying. Since the launch launching in March this year, facing the problem of heavy tasks, tight construction, and cross -operating surfaces in the face of rail labing work, and the huge challenge brought by the 25 ‰ of the Longshang Road to the rail launch construction, the builders of the 4th Bureau of the China Railway have continuously optimized the construction plan for the construction plan. And resource allocation, increase the rail paving unit to 2 groups, increase the mobile flash welding unit to 3 groups, and organize personnel to work for 24 hours to make people stop and continue to create a high -yield record. During the construction period, the builders adhered to standardized and refined management, coordinated the promotion of projects such as the launch of non -砟 砟 and the laying of long steel rails. Control, eventually achieved the entire line in June this year.

Designed by the China Railway Second Court, the "Four Electricity" system integration project undertaken by the China Railway Tenth Bureau and the China Railway Wuhan Electricization Bureau started construction in November 2021. The project department strengthened resource allocation, scientific deployment, careful organization, and solidly promoting construction and production with the attitude of "starting is sprint and construction is a decisive battle."

In the introduction of the Four Electric Power Project of Jinan East Station in Jilai high -speed rail, the builders of the Tenth Railway Bureau have undergone nearly 600 points to overcome (near) the business line at night construction safety pressure, high technical complex requirements, multi -professional cross construction difficulty, etc. The unfavorable factors have successively completed the tasks such as power construction, contact network delivery, and contact network thermal skid test of Jinan East Station, and successfully fulfilling the goals of various nodes, which provides a strong guarantee for the joint adjustment and joint trials as scheduled.

China Railway Science and Industry Relief Equipment is adding high -speed rail construction

During the construction of the Galaxia Gridge beams, the first new 800 -ton bridge machines of China Railway Industry under the China Railway Industry were successfully put into use for the first time. The technicians completed the equipment research and development and production in just 6 months, and took one month to complete the on -site assembly of the equipment, refreshing the record of the new equipment of the unit.
