Our company participated in the trackless construction of the entire process of laying tracks for Nanjing Metro Line 7, exploring innovation and keeping pace with the times

On site shooting: Loading materials at the wellhead of a self deformable concrete construction vehicle

The concept of 'trackless track laying' is not unfamiliar in subway track construction, but we are at the forefront of fully realizing trackless operations throughout the entire process nationwide Project manager Li Dong introduced it. Trackless track laying "refers to the use of tire type track cars, tire type track laying machines, and self deforming concrete tankers to replace traditional track flat cars, wheel rail track laying machines, and concrete hoppers for track laying operations. Compared to traditional subway track laying, "trackless track laying" not only has fast construction speed and simple procedures, but also has flexible use, convenient transfer, and higher automation level, greatly improving construction efficiency and reducing construction costs.

 In the process of pouring the roadbed, the transportation of fresh concrete is crucial. In traditional construction, concrete transportation requires at least 3 transfers, and the loss of mortar during the process can lead to a decrease in concrete quality. The use of self deformable concrete construction vehicles not only solves the problems of long transportation time and multiple transportation links for concrete over long distances, but also ensures sufficient mixing of concrete during transportation, greatly improving construction efficiency and ensuring project quality.

  The self variable rail concrete construction vehicle is a new type of specialized concrete construction equipment developed for rail transit construction, with multiple functions such as concrete transportation, mixing, and material distribution; It can operate on various foundations such as standard tracks, construction tracks, curved tunnel surfaces, trapezoidal sections, and flat surfaces; Widely used in high-speed rail, urban rail transit, tunnel, bridge construction, etc.

Anhui Xingyu Rail Equipment Co., Ltd. has actively coordinated, boldly innovated, allocated sufficient construction resources, upgraded and renovated tooling since the project entered the site, and made sufficient preparations for subsequent construction. The successful completion of the "full process" trackless track laying test has laid the foundation for the smooth completion of engineering construction tasks.
