Recently, the Beijing Zhan Tianyou Civil Engineering Science and Technology Development Foundation of China Civil Engineering Society announced the list of candidates for the 20th China Civil Engineering Zhan Tianyou Award. Fourteen projects participated by China Railway Construction won this honor, and the number of awards reached a record high.

Let's take a look at how spectacular the "Oscar" in the construction industry is! Ccement. Com/richtext/IMG/brwno4au2ep1681794855281. The construction team actively carried out technical research, innovatively developed and applied intelligent construction technology, and overcome the difficulties of shield launching and receiving in ultra-shallow depth and crossing important buildings and structures in ultra-short distance. Shield construction has successfully passed through several sensitive buildings around the core area of Beijing, and has been completed four months ahead of schedule, setting up a new "fashion standard" for the construction of high-quality intelligent passenger stations in the new era.

Relevant projects have won the Railway Quality Engineering Award, the first prize of Beijing Science and Technology Award, 24 invention patents and 3 provincial and ministerial construction methods. In 2018, the segments of the Beijing-Zhangjiakou Tunnel were exhibited and permanently collected by the Eastern Suburb Museum of the China Railway Museum. Maintenance and Operation Guarantee Project

of China Southern Airlines Base of

Beijing New Airport China Railway Construction Co., Ltd. participated in the maintenance and operation guarantee project of China Southern Airlines Base of Beijing New Airport, with a total construction area of nearly 20. It is of great significance to enhance the international competitiveness of China's civil aviation and promote the coordinated development of Beijing, Tianjin and Hebei.

In the process of construction, the construction team independently invented the "combined ceiling" to solve the problems of special-shaped aluminum plate assembly and hot-melt tension soft film lighting structure, which ensured the beautiful effect of the operation and control hall. At the same time, through the research and development of the national patent of "assembled integral mobile operation frame", they ensure the rapid installation and construction accuracy of the special-shaped perforated aluminum plate composite ceiling in the operation and control hall.

construction process, the project team has overcome a large number of construction problems and created many "firsts" in the history of cable-stayed bridge construction in China. It is the first time to use the same-direction slewing cable technology on a long-span bridge, which has avoided the problem of tower column cracking, and has become an important milestone in the history of cable-stayed bridge construction; it is the first time to use the arc-bottomed steel box girder for a super-long-span cable-stayed bridge with strong wind resistance; it is the first time to use the symmetrical cantilever assembly technology for all girder sections, with the maximum cantilever length reaching 397 meters, which has set a new record for the construction of cable-stayed bridges in China.

Cuijiaying Hanjiang River Bridge is a rigid frame-arch combination bridge." The span of concrete beam of high-speed railway in China has been successfully raised from 200 meters to 300 meters, which provides a pioneering example for the bridge engineering of large-span high-speed railway.

Three research projects of the project have reached the international leading level, with 6 + 3 authorized invention patents and 7 authorized utility model patents. The construction experience has been promoted and applied in more than 40 swivel bridges to varying degrees.

Among them, the Hanjiang River Bridge is the key control project of the Haoji Railway." It is the world's first heavy haul railway concrete partial cable-stayed bridge. During the construction, the key construction technology of the self-developed heavy-haul railway low-pylon cable-stayed bridge has reached the leading level in China, and the hanging basket construction part has reached the international advanced level, which provides valuable experience for other major bridge projects in China. In addition, the 8th tender section of the whole line has become one of the first tender sections to pass the A-level identification of technical quality. During the construction, technological innovation has been strengthened to tackle key problems and overcome the geological problems in the construction of collapsible loess plateau tunnels.

Ya'an-Kangding Expressway Erlangshan Tunnel

China Railway 12th Bureau participated in the construction of Yakang Expressway Erlangshan Tunnel, known as "the first tunnel in Sichuan and Xizang". During the

construction process, the construction team successfully solved the construction problems such as long-distance single-head tunneling, three-level strong rock burst, high-pressure and large deformation of surrounding rock, mud and water inrush, etc. The artificial drilling and blasting method for single-head excavation in the earthquake fault zone was created 7333.

construction, the builders first used the plant-mixed cold recycling technology of emulsified asphalt, which not only reduced the land pollution and the development of non-renewable resources, but also reduced the emission of harmful materials, and had obvious advantages in road recycling. At the same time, the builders also used new paving equipment for the first time in the construction. Breaking through the asphalt surface 18.

, the construction team built 141 kilometers of construction roads. It has conquered the most difficult "geological museum" of the whole line and refreshed the construction record of China's expressway. The construction team also broke the traditional construction technology, adopted repeated backfilling of rubble, clay and cement to more than 210 cubic meters, and adopted double-layer steel casing follow-up measures to deal with the construction of karst cave pile foundation. In addition, their self-developed "GPT Tunnel Advanced Geological Prediction New Technology" has reached the international advanced level and achieved zero defects in the quality of engineering entities. Among them, Dayaoshan No.1 Tunnel won the Luban Award in 2017.

that the track laying construction task carried out by the construction team of CRCC is the first time that the prefabricated slab track is widely used in the subway construction in China Bed structure. The completion of this structure solves the technical problems affecting the construction quality of seamless track, and sets a benchmark for the standardization and standardization of the structure of precast slab track bed. In addition, the construction team also summarized and refined the innovative management methods of shield construction "iron nine" and segment assembly "cross formula", and related projects have been awarded the Shanghai Municipal Engineering Gold Award, Shanghai "Star Site" and other honorary titles.

Qingdao Metro Line 2 Phase I Project

China Railway 12th Bureau, China Railway 17th Bureau and China Railway 18th Bureau participated in the construction of Qingdao Metro Line 2 Phase I with a total length of 25

. Zaoli section has successively passed through the tunnel under construction of Metro Line 3, Licun River, Licun Business Circle and other complex environments, and the builders have adopted the construction method of zero-spacing undercrossing the existing metro tunnel in the water-rich fault zone to create a metro construction record of ultra-close undercrossing the tunnel under construction, ultra-high standard control of vibration velocity, and ultra-technical level to avoid building damage. This technology won the second prize of scientific and technological progress of China Construction Enterprise Management Association in 2017 and the provincial construction method of Shanxi Province in 2018.

The tunnel passes through the huge "Karst Hall" with the largest volume, the most complex geology and hydrology, and the most difficult treatment in the history of high-speed rail construction in China. The construction team overcomes the challenges of high construction safety risk, short construction period, strict requirements for high-speed rail track settlement, and high environmental protection requirements, and skillfully uses 1 million cubic meters of tunnel waste slag to backfill the karst cave. Its innovative construction technology of tunnel passing through huge karst caves provides a vivid example for the construction of tunnels with the same type of geological conditions, which is a milestone in the history of railway tunnel construction in China.
