Hubei: Jiangxia, a new intelligent prefabricated building industry base, put into production

Welding robots automatically weld steel skeletons, mold cleaning and spraying robots efficiently clean molds, spray mold release agents, independent steam curing cellars, intelligent temperature control and curing of concrete segments... On December 23, Wuhan Zhiyuan Jinghan Construction Technology Co., Ltd.'s new intelligent prefabricated construction industrial base in Jiangxia District was officially put into production. The tunnel segments produced will be used in the construction of key projects in Wuhan.

In the morning of the same day, the reporter saw in the production workshop of the base that a complete tube segment production line has been completed and all kinds of supporting machinery and equipment are readily available. In the steel bar processing area, the blue robot with the shape of a huge arm is particularly eye-catching. After receiving the work instruction, the robot starts to adjust the position of the arm, automatically finds the welding point, and performs welding according to the set route.

"The steel skeleton of the prefabricated component is manually welded, so the precision control is not enough and the efficiency is low." On-site staff told reporters that the base can significantly improve the efficiency and quality of welding by designing a dedicated workbench and matching welding robots, and avoid the safety risks of manual operations.

The mold cleaning robot on the fully automatic assembly line is white, waiting quietly next to the steel mold. This kind of robot can efficiently clean the concrete residue in the mold, avoiding the omission of the position in manual cleaning. The spraying robot sprays the release agent more evenly than the manual, so that the tube sheet and the steel mold can be separated better, and the production efficiency is greatly improved.

According to the staff, the entire production process is as follows: the welded steel cage is placed in the mold, then the embedded parts are installed, the concrete is poured, and then the concrete is wiped and wiped, steam curing, demoulding, water curing in the pool, and standing in the storage yard.

“Our production line draws on the domestic cutting-edge production technology and technology to achieve industrial upgrading, lower cost than traditional processes, safer, more environmentally friendly production, and easier to control quality.” The staff member said.

Wuhan Zhiyuan Jinghan Construction Technology Co., Ltd. is jointly invested and constructed by Wuhan Hanyang Municipal Construction Group Co., Ltd., Wuhan Yucheng Construction Group Co., Ltd., and Shanghai Tunnel Engineering Co., Ltd. Its prefabricated construction industry base is located in Wulijie, Jiangxia District, covering an area of 106 acres. After completion, it can produce 200,000 cubic meters of large-scale precast concrete components and 1 million cubic meters of ready-mixed concrete.

It is understood that the base is designed and constructed in the direction of green buildings and intelligent manufacturing, and through the integration of project construction information and intelligence, it has made in-depth advances in the field of intelligent manufacturing of prefabricated components. In the near future, it serves the prefabricated component business such as rail transit, tunnels, underground comprehensive pipe corridors, and PC components. In the long term, it explores feasible solutions for the development of informatization and intelligentization of the industry.
