Line 5 of Hefei City, Anhui Province, the first subway "prefabricated machine room" appeared

When the prefabricated building "meets" the subway project, it can not only shorten the construction period and reduce material waste, but also realize smoke-free and dust-free construction in a small underground space. Recently, the reporter learned from Hefei Rail Station that the prefabricated ventilation and air-conditioning machine room and chilled water machine room of Jiqiao Road Station on the northern section of Metro Line 5 passed the first acceptance, and through technological innovation, the application of prefabricated buildings in rail transit was promoted.

Ventilation air-conditioning and chilled water machine rooms are the heart of the cold source of air-conditioning in subway stations, and are the places where refrigerants are directly generated. The reasonable layout of a computer room not only meets the functional requirements of subway lines, but also reduces operating energy consumption and facilitates management.

The machine room of Jiqiao Road Station on the northern section of Metro Line 5 under construction will be installed in-depth by the assembly electromechanical factory of the Third Company of China Construction Fifth Engineering Group Co., Ltd., and adopt information technology to deepen the design and modeling. Compared with traditional construction procedures, 90% of collisions in the process of electromechanical installation engineering are effectively resolved in advance; the three-dimensional virtual view is also more intuitive and convenient than traditional design drawings, and better quality control can be performed. At the same time, prefabricated pipes were carried out through the prefabricated factory, saving 30% of construction materials.

"Compared with the traditional construction mode, this avoids the limitation of installation project site, greatly shortens the construction period, effectively reduces the waste of materials, and realizes the whole process of construction in a smoke-free and dust-free environment." Introduced by the relevant person in charge of Hefei Rail Station.

The use of the prefabricated computer room at Jiqiao Road Station has played a role as a model guide for the construction of "quality subway and green subway", which in turn facilitates the calibration of the whole line and the promotion of the whole line.
