Since entering the 21st century, tunnel engineering construction has entered a new stage of development, and more and more plans for the construction of long highway tunnels have been included in the plan. China's tunnel construction technology has gradually transitioned from manual excavation to semi mechanized construction, and is now shifting towards a combination of manual labor and large-scale mechanical construction. This transformation not only improves construction efficiency, but also reduces manual labor intensity, making tunnel construction more efficient and safe. With the advancement of technology and the improvement of mechanization level, more and more tunnel construction projects are adopting large-scale mechanical equipment.

　　Advantages of concrete wet spraying robotic arm
