According to its location, it can be divided into three categories: mountain tunnels, underwater tunnels and urban tunnels. Mountain tunnels are tunnels that pass under mountains or hills to shorten the distance and avoid steep slopes. Underwater tunnels are tunnels that pass under rivers or seabeds to cross rivers or straits. Urban tunnels are tunnels 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.

[0040] Working principle: A method for using a tunnel 1 inner wall flattening device, the steps are as follows:

[0041] The first step is to tidy up the ground inside the tunnel 1 to ensure a certain degree of flatness, to facilitate the longitudinal movement of the mobile vehicle in the tunnel 1, and to reduce the fit between the front end suction bucket 11 of the swing bracket and the inner wall of the tunnel 1.

[0042] The second step is to drive the mobile vehicle into the tunnel 1, and the swing bracket 10 is at the initial end of the inner wall of the tunnel 1;

[0043] The third step is to start the swing motor, which drives the reciprocating swing mechanism, and the reciprocating swing mechanism drives the swing bracket 10 to swing synchronously, thereby starting the driving vehicle to move longitudinally in the tunnel 1 at the same time, so that the suction bucket 11 moves in a spiral along the curved inner wall of the tunnel 1;

[0046] In summary,

[0047] The inner wall leveling device for construction of tunnel 1 is designed to have a reciprocating swing mechanism on a mobile vehicle to drive a swing bracket 10 according to the arc-shaped inner wall of tunnel 1. During the longitudinal movement of the mobile vehicle, the swing bracket 10 reciprocates and spirals forward on the inner wall of tunnel 1 to "walk" to complete the leveling operation, thereby improving the leveling efficiency and reducing labor intensity.

[0048] The tunnel 1 is constructed with an inner wall leveling device, and a suction bucket 11 is arranged on the top of a swing bracket. The rotating roller 13 is rotated under the drive of a scraper motor 15. After the inner wall of the tunnel 1 is leveled, a vacuum fan 23 generates a negative pressure in the suction bucket 11, and the shoveled dust is sucked into a collection box 25, which is convenient for centralized treatment and reduces the dust pollution in the tunnel 1 space.
