The heavy weapons of the big countries are frequently new

The "Iron Dragon" keeps digging

In the exhibition hall of China Railway Construction, the ultra-large diameter shield machine with completely independent intellectual property rights jointly developed by China Railway Construction Heavy Industry and China Railway 14th Bureau - "Jinghua" was unveiled, showing a typical sample of the continuous and deep integration of advanced manufacturing and scientific and technological innovation in mainland China.

On June 29, the reporter saw at the booth that the equipment model was displayed in a scaled scale, but it was still possible to imagine its complex structure.

The shield machine is a high-end tunnel boring equipment integrating a variety of technologies, with more than 30,000 parts, and has the title of "King of Construction Machinery".

The total length of the "Jinghua" shield machine is about 150 meters, and the maximum excavation diameter is 16.07 meters, which is the first 16-meter ultra-large diameter shield machine in China.

According to the on-site staff, the shield machine is like a steel "pangolin", which can drill tunnels in the mountains, underwater and underground in the city, which is both efficient and safe. "Because the shield machine excavation, soil discharge, slag removal, support, lining, sealing, in one go, the main structure of the tunnel is formed at one time, so the technical requirements for the shield machine are too high."

Next to the shield machine display stand, the world's largest 8.61-meter-diameter shield machine integral main bearing, which is the "heart" of the shield machine. It is displayed in a scale of 4.4 and so on, and the real diameter spans three floors, weighs 62 tons, and has a maximum load of 10,000 tons.

According to the staff, its raceway diameter is several meters, the flatness is less than 20 microns, which is equivalent to one-fifth of the thickness of an A4 paper, and the straightness is less than 8 microns, which is only one-tenth of a hair. This process is tantamount to "carving words on hair and carving on grains of rice".

It is such a piece of equipment, which has been widely used in the construction of large-scale projects such as railways, highways, mines, and water conservancy at home and abroad.

In addition to the shield machine, the intelligent inspection robot of the construction site is also attracting attention. It is about 1.5 meters tall and can automatically scan on-site obstacles, independently plan routes, and perform inspection tasks 24 hours a day.

Xu Zhaoyang, manager of the marketing department of China Railway Construction Group Co., Ltd., said that the robot can actively identify potential safety hazards such as abnormal environmental conditions and workers' non-standard behaviors on the construction site, automatically capture, analyze and store and send them to the smart construction platform synchronously, which greatly improves the intelligent safety management level of the project.

In this expo, China Railway Construction brought more than 60 exhibits from 17 of its units to the exhibition, presenting a complete set of solutions for the whole process and full cycle of intelligent survey, intelligent design, intelligent construction, and intelligent operation and maintenance.

The intelligent assembly bridge building machine has created a new record in the field of bridge erection construction in China, and opened a new mode of viaduct assembly construction.

This intelligent assembly bridge building machine was developed by China Construction Eighth Bureau for one year, and is a large-scale municipal highway construction intelligent machinery integrating pier columns, cap beams and box girder installations. It is very large, with a length of 76.5 meters, a width of 15 meters, a height of 15.5 meters, and a total weight of 360 tons.

"So how do you pinpoint it in the air?" Chen Xibin said that the equipment is equipped with Beidou navigation and positioning system and visual aided AI system, which can realize the fully automated installation of bridge construction, and the efficiency of the installation process is increased by more than 20%.

The intelligent assembly bridge building machine is just a microcosm of the core technology and equipment of bridge construction continued to be cultivated by China Construction Eighth Bureau. The reporter saw that the scene also displayed visual measurement robots, wall-climbing robots, ground penetrating radar robots and other intelligent equipment.

"We entered the Xinjiang market in 2018 and have undertaken more than 50 key construction projects, and have also applied a number of black technologies such as intelligent construction robots." Chen Xibin said that at the expo, China Construction Eighth Bureau set up five major plates, in the form of graphics, models, videos and other forms of display, all-round and in-depth display of the development achievements of China Construction Eighth Bureau, focusing on the Urumqi Airport reconstruction and expansion project, Egypt's new administrative capital central business district and other representative projects and the "Tiangong Kaiwu" intelligent manufacturing system, take the opportunity of this expo to continue to participate in the construction of the "Belt and Road" with high quality, provide China's smart construction solutions, and contribute more positive forces to promote the construction of a community with a shared future for mankind.

The construction elevator can be rotated 180°

The building machine is one floor in 4 days

At the booth of China Construction Third Engineering Bureau, the 180° rotating "smart" elevator, 5G unmanned tower crane, and "light building machine" model demonstrated the innovative achievements of "Made in China".

Before the circular construction of the elevator model, there are 4 elevators working between different floors, Liu Huidong, chief engineer of Xinjiang Branch of China Construction Third Bureau, opened the model button, the reporter saw that the elevator began to move slowly, and when it climbed to the top of the floor, the elevator automatically rotated 180 ° and began to descend from the other side.

Liu Huidong said that this is the independent research and development of China Construction Third Bureau, the world's first "single tower multi-cage circulation construction elevator", to overcome the construction of high-rise buildings with multiple elevators to occupy more work surface and other problems, through a single rail frame to hang a number of construction elevator cages, and set up a rotating rail change mechanism, to achieve the ladder cage at high altitude rotation 180 ° change track, greatly improve the efficiency of material transportation.

In the "5G tower crane simulation cockpit", tower crane operator Zhao Gang is demonstrating how to control the tower crane at the construction site of the Hippo Spring Sewage Treatment Plant in Urumqi, dozens of kilometers away, through his operating stick. "Now you can open the tower crane while sitting in the office, and you can also accurately lift the building materials and put them into the designated construction site." Zhao Gang said that in the past, it was necessary to climb to the top of the 100-meter-high tower crane to operate, and it was not easy to operate the next time.

At present, China Construction Third Bureau has applied 5G remote tower crane operating system at the Urumqi construction site, and is communicating with relevant functional departments to conduct research and is expected to put into use the "light building machine" equipment in the Urumqi construction market, which is a new intelligent assembly integration platform suitable for building construction below 100 meters, and can build a floor in 4 days at the earliest.

Focusing on the "new technologies, new products, new models and new formats" brought about by the transformation of "digitalization, greening and operationalization" in the construction industry, China Construction Third Engineering Bureau has actively established the "Intelligent Construction Research Institute" and developed and applied a series of intelligent construction "artifacts" to help cultivate new quality productivity in the construction industry. The company has applied more than 50 intelligent construction technologies to a number of projects such as the terminal of the Urumqi Airport Reconstruction and Expansion Project, the Urumqi Cultural Science and Technology Innovation Talent Building, and the Lianggang Industrial Park.

Liu Huidong said: "We hope that through this expo, we can demonstrate the advancement and practicability of China's intelligent construction technology, and also hope that these advanced experiences will provide new development solutions for urban construction and development in the country and Central Asia." ”
