The utility model relates to a tunnel construction technical field, in particular to be used for tunnel slot construction equipment. This be used for tunnel slot construction equipment includes door frame of the trolley, establishes door frame of the trolley lift cylinder on door frame of the trolley, establishes the walking wheel at the bottom of door frame of the trolley lift cylinder, establishes the actuating system in door frame of the trolley the place ahead or rear, , the door frame of the trolley top establishes the cantilever beam on setting a roof beam in place, establish smooth roof beam at cantilever beam left part cover, establish cantilever beam translational oil cylinder on the cantilever beam of smooth roof beam top right side, at smooth articulated trolley template in roof beam below and slot inner formword, connect trolley template hydro -cylinder and slot template drawing of patterns hydro -cylinder respectively on trolley template and slot inner formword, play to rise the hydro -cylinder establishing the outer wall template between smooth roof beam and door frame of the trolley at the bottom of the cantilever beam, at the outer wall template articulated outer wall template translational oil cylinder's in bottom right side cylinder bottom. This be used for tunnel slot construction equipment has avoided manual operation inefficiency and the low problem of precision, and the engineering time very reduces, is superior to the construction of the small -size steel form of traditional combination formula.
