The underground "building blocks" to build a subway station, Wuhan's "national team" has a new action

The Yangtze River Daily Da Wuhan client August 14th. It is not new to build a house like a building block, but it is not easy to achieve this operation underground. On the 14th, a reporter from the Yangtze River Daily learned from the China Railway Fourth Survey and Design Institute Group Co., Ltd. that the construction of the Wuhan Qianchuan Line Tomhama Division No. 2 in the construction of the construction was under the construction of underground assembly support.

Stacking assembly underground station trial assembly.

The construction of traditional subways, due to the narrow underground space, extensive construction methods, large use of labor demand, high pollution emissions, and large energy consumption. In response to this series of issues, the III Court took the lead in developing the equipment for assembly stacked underground stations in China.

To put it simply, you can compare a station to a whole. Construction, decoration, pipeline and other solutions are "packaged". All design is standardized. All construction steps are simulated with three -dimensional dynamic simulation in advance. Is there a problem with the anti -collision?

Equipped with overall underground stations.

"The benefit of prefabricated intelligent construction technology is that the strata adaptation, wide structural adaptation, good waterproof performance, light prefabricated components, fast node connection, high assembly efficiency", Xu Junlin, deputy chief engineer of Tie Four Courtyard Urban Place The No. 2 wind well in Toma Division is the support of hollow steel fiber designed by the III Courtyard. It can withstand complex stresses such as bending and cutting, which is 40%more efficient than before. In the second phase of Wuhan Metro Line 3, due to the introduction of prefabricated intelligent construction technology, the construction period was 30%saved than the original expected.

In recent years, the Tie Fourth Court has taken root in urban rail transit, and has gradually created and formed and formed "TOD development, fully automatic operation, energy intelligent management, prefabricated intelligent construction, overall underground space, intelligent power supply, intelligent operation and maintenance, and comprehensive monitoring, comprehensive monitoring, and comprehensive monitoring, and comprehensive monitoring, and comprehensive monitoring, and comprehensive monitoring, and comprehensive monitoring, and comprehensive monitoring, comprehensive monitoring, comprehensive monitoring, and comprehensive monitoring, comprehensive monitoring, and comprehensive monitoring, and comprehensive monitoring, comprehensive monitoring, and comprehensive monitoring, and comprehensive monitoring, "Cost big data and asset operation management" eight breakthrough innovation technologies. Among them, fully automatic operation technology provides high efficiency and convenience for citizens to travel.

Wuhan Metro Line 5.

On December 26, 2021, Wuhan Metro Line 5 was opened. This line is the first subway line in Wuhan to use fully autonomous driving. Sitting in the subway, as if taking a "time shuttle".

It turned out that the III Court achieved 108 full -scene applications on Metro Line 5, which increased the point rate of the train from 99.89%to 99.99%.

Urban rail transit energy intelligent management system.

According to Liu Tao, deputy chief engineer of the Terrace Council, the full automatic operation technology enables the train system to realize intelligent scheduling and flexible marshals. The system can allow the train to operate separately during Pingfeng. There are more trains. This change reasonably optimizes the full load rate of trains in each period, and the failure rate has also decreased significantly.

Today, many unknown corners of subway stations are gradually changing people's lives.

Intelligent power supply technology.

A CO2 sensor can feel the temperature of the environment and the density of the flow of people in real time. After receiving the data, a dynamic adjustment of a dynamic adjustment of "people with more people, people with less people" can be made in conjunction with the station environment of the urban rail energy intelligent management system (UIEMS). Essence On the stations, this system can also combine natural light and advertising lighting to adjust the light illuminance in real time. After a year, carbon dioxide emissions can be reduced by 2.44 million tons.

On August 11, the Urban Underground Space R & D Center led by the Fourth Court of Iron Court passed the acceptance of licenses in China Railway Construction Engineering Laboratory (R & D Center). As the leader of the Chinese high -speed rail, the relevant person in charge of the Fourth Hospital of Iron said that it will continue to develop breakthrough innovation technology to make the people live a better life.
