China Construction Machinery Information

Changsha secondary industry park project of China railway construction heavy industry is located in Changsha Economic Development Zone, with a total planned investment of more than 5billion yuan. The first phase of the project is 547 mu, which is mainly used for the production of special equipment and the remanufacture of shield machines. The second phase is 329 mu, which is mainly used for the production of Maglev tracks. Phase I and phase II will be put into operation in May this year. After all the projects are completed, the annual output value of CRCC heavy industry will exceed 10billion yuan

six months ago, the northeast of the East 11th Road of Changsha Economic Development Zone and the airport expressway was covered with yellow mud. Now, there are many factories here, and the newly planted street trees along the road are green and bright in the sun

the workshop with sky blue roof belongs to China railway construction heavy industry group. After more than 8 months of construction, a total investment of 5billion yuan of railway construction heavy industry Changsha secondary industry park base is ready to emerge

"the production equipment will be mobilized for installation and commissioning, and the first and second phases will be put into operation in May this year." Introduction by shenzhifang, chief planner of China railway construction heavy industry group Co., Ltd

this year is the tenth year that CRCC heavy industries has settled in Changsha. The sword has been sharpened for ten years, and the frost blade shows its sharp edge. In the shield machine market, CRCC heavy industry occupies half of the country, and in the TBM field, its market share is as high as 70%

greater ambition is concentrated in the new projects of CRCC heavy industries. The world's first intelligent maglev track system production line with independent intellectual property rights related to the clamping mode of the jigs of Jinan assaying tensile testing machine will be put into production and supply in the second half of this year

"whether in terms of production capacity or technical standards, we always keep the supply of waste plastic particles short of demand to be the first in the world." Shenzhifang was excited and proud

direct attack on site

nearly 2000 people worked overtime to rush for the construction period

under the blue sky and white clouds, the two steel structure plants looked particularly majestic

walking into the factory, we saw that the workers were laying logistics running tracks on the ground, and several vehicles with a total load of 200 tons in the air were also being debugged

"the main works of phase I administrative office building and two span workshop steel structure have been completed, and the capital construction work has been basically completed." Zhangzhizhong, the infrastructure administrator, disclosed that since last year, the project has been affected by two long rainy periods, and the progress is slightly behind. In order to smooth the trial production as soon as possible, nearly 2000 people worked overtime during the hottest period of project construction

at the scene, the author ran into several experts from the supervision company. They were wearing safety helmets and were investigating potential safety hazards one by one

"the equipment is about to enter the site, and the safety supervision cannot be relaxed." Yangchenglin, the director of the project Department of the supervision company, told the author that in addition to the construction unit, the supervision project department implements the system of twice a day and once a month

every time, yangchenglin would hang a "magic weapon" - a telescope around his neck. "The plant is high and there are many high-altitude operations. It is not clear when standing on the ground. It is convenient and careful to use it for inspection." Yangchenglin's dark face showed a smile when he saw that the project was being built in quality and quantity

the annual production capacity of maglev rail is 60000 meters

in one corner of the plant, there are several large wooden boxes. "In the box are the assembly parts of phase I production line. As soon as the ground construction is completed, they can be assembled and debugged." Zhangzhizhong introduced to the author that the project plans to introduce 15 production lines

special construction equipment for tunnel, shield remanufacture and magnetic levitation track equipment are the three major sectors of Changsha secondary industry park in the future. Special construction equipment, including concrete wet shotcreting machine, anchor digging machine, concrete spraying trolley and three arm rock drilling trolley, will fill the gap in the domestic market, and the production capacity of shield machine will also reach a new level

"at present, the construction application procedures for phase II have been completed, and the construction of plant roads is being accelerated." Shenzhifang said that at present, CRCC heavy industry has obtained the supply order of Guangdong maglev rail system. It should seize the opportunity, seize the construction period, launch the intelligent maglev rail system production line as soon as possible, and strive to put into production and supply in the second half of this year

different from the traditional production line, this new production line can realize automatic clamping and positioning of workpieces, intelligent detection, NC program processing, automatic handling and turnover, automatic assembly and coating, and realize the industrialization of track system (rail row and turnout) through series or parallel assembly line production. It can produce 60000 meters of magnetic levitation track every year, and 15 sets of magnetic levitation turnouts per year, which is worthy of being the first in the world

"after all the projects are completed, it can quickly boost the annual output value of CRCC heavy industry to exceed 10billion yuan and provide employment opportunities for 3000 people." Shenzhifang said that a high-end underground equipment intelligent manufacturing industrial base integrating R & D, manufacturing, service and remanufacture will also stand in Xingcheng

project highlights

provide strong support for building an upgraded version of Changsha economy

the Changsha secondary industry park project of China railway construction heavy industry is a typical sample of high-end manufacturing industry in Changsha Economic Development Zone

in order to promote the construction of the project, zhangqinghong, deputy secretary of the Party Working Committee and deputy director of the Management Committee of Changsha Economic and Technological Development Zone, went to the project site for many times, and opened a "green channel" for enterprises, so that the construction application procedures that would have taken more than 6 months to be completed could be completed in just over 1 month

"Taking Changsha as the base, CRCC heavy industries radiates the whole main chain including C countries, goes global, and sets the benchmark of 'made in China'. Now, it is full of entrepreneurial passion and strives to build a 'model' enterprise for transformation, upgrading and development." Zhangqinghong said that the completion of the Changsha secondary industry park project of China railway construction heavy industry will help the park develop high-end manufacturing, promote the transformation from "made in Changsha" to "made in Changsha", and provide strong support for building an upgraded version of Changsha economy

builder's story

"holding your finger" rush period

it took a lot of effort to successfully ask zhuwenfeng for an interview. As the Vice Minister of the strategic investment department of China railway construction heavy industry, and also the person in charge of the infrastructure construction of new projects, zhuwenfeng has started the days of running at the head office and new projects since last June

on April 18, when the author was at the project construction site, zhuwenfeng was having a meeting with his colleagues to coordinate all parties of phase I project, refine construction details and standards, and realize production as soon as possible

early the next morning, zhuwenfeng flew to Baotou again, waiting for him for a few days of intensive travel. "Baotou Metro Company intends to cooperate with us to develop shield machine." Zhuwenfeng revealed that China railway construction heavy industry also plans to set up a branch in Baotou city. His trip this time is to "play a leading role"

in the past nearly a year, "they all came by breaking their fingers for a day". Zhuwenfeng said that the work of looking at the land, applying for construction, starting construction, land leveling, plant construction, etc. were all tackled one by one by sticking to the time node, "the construction period is very tight"

"orders are waiting for us. Our goal is to put into production as soon as possible." Zhuwenfeng, who was bent on the construction site, was confident
