Description

Technical Field

[0001] The invention belongs to the technical field of shotcrete tracked vehicles and relates to an electric mechanism of a shotcrete tracked vehicle. Background Art

[0002] A tunnel is a structure built underground, underwater or in a mountain for laying railways or building roads for the passage of motor vehicles. According to its location, it can be divided into three categories: mountain tunnels, underwater tunnels and urban tunnels. Mountain tunnels are those that pass under mountains or hills to shorten the distance and avoid steep slopes; underwater tunnels are those that pass under rivers or on the seabed to cross rivers or straits; urban tunnels are those that pass underground in cities to meet the needs of railways passing through large cities. Mountain tunnels are the most commonly built of the three types of tunnels, and shotcrete tracked vehicles are often required during tunnel construction.
