Problems solved by technology
[0004] In view of the above-mentioned related patents, the inventor believes that when the scraper moves up to remove the mud protruding from the inner wall of the tunnel, the scraper cuts through the transverse shear stress applied to the mud, so that part of the mud is easily driven by the scraper from the inside of the tunnel. The wall falls, resulting in a crater in the inner wall of the tunnel

The invention relates to an inner wall leveling device for tunnel construction, and relates to the technical field of tunnel construction equipment, in order to solve the problem that when the inner wall of a tunnel is shoveled, a pit body is likely to be formed in the inner wall of the tunnel, the inner wall leveling device comprises a base, a guide rod is arranged on the base, a mounting plate is slidably connected to the guide rod, and the mounting plate is obliquely arranged; a plurality of rotating shafts are rotationally connected to the side wall of the mounting plate, and first cutting discs are arranged at the ends of the rotating shafts; a transmission belt is wound on the rotating shafts, and a driving part for driving the transmission belt to rotate is arranged on the mounting plate; and a power unit for driving the mounting plate to move is arranged on the base. The method has the effect of reducing the situation that pits are generated on the inner wall of the tunnel when the inner wall of the tunnel is leveled.
Description
technical field [0001] The present application relates to the technical field of tunnel construction equipment, in particular to an inner wall levelling device for tunnel construction. Background technique [0002] When the tunnel is just dug through, the inner wall of the tunnel is uneven, which will affect the construction efficiency and construction quality of the subsequent construction in the tunnel; the inner wall leveling device for tunnel construction is the device used to level the inner wall of the tunnel. [0003] The related patent with the announcement number of CN108612538A provides a tunnel inner wall levelling equipment for tunnel construction, which includes a cart, the top wall of the cart is provided with a screw rod and a slide rail, and a mounting plate is mounted on one side of the slide rail; the side wall of the mounting plate is provided with There are sliders and connecting rods, the sliders are slidably connected to the slide rails, the end walls o...
