At the meeting, the experts listened carefully to the detailed report of the Wuxin Tunnel installation and believed that the project had the following innovations:

(1) The use of a mature automobile chassis can take into account the construction requirements of multiple tunnel heads, with strong mobility, convenient transition, and high construction efficiency.

(2) Developed the pumping hydraulic system's peak-filling technique to reduce the pulsation during concrete spraying, reduce the segregation of concrete and excessive accumulation of accelerators, and improve the injection quality.

(3) Using CAN bus control technology, equipment operation realizes functions such as automatic control, real-time monitoring, remote fault diagnosis and maintenance.

(4) Developed a kind of extended concrete spraying vehicle manipulator with high strength, good rigidity, light weight and wide construction range.
