Scraper system for leveling filling surface of tunnel inverted arch

Abstract

The utility model relates to a scraper system for leveling a filling surface of a tunnel inverted arch, in particular to a scraper system for leveling the filling surface of the tunnel inverted arch. The scraper system is mainly designed for solving the problem that the gradient of the tunnel inverted arch is difficult to control at present. The scraper system comprises two rectangular channels, a vertical long hole is formed in the vertical edge of the front side of each channel, a round hole is formed in the vertical edge of the rear side of each channel, two shafts are welded to the rear portions of the left side and the right side of the trestle respectively, the shafts are sleeved with the round holes in the channels, adjusting bolts are arranged in the vertical long holes in the channels, and the adjusting bolts are fixed to the front portion of a trestle. Each channel is internally provided with two steel wheels, the outer ends of steel wheel shafts of the two steel wheels are connected to the upper ends of triangular fixing frames, upper screws are welded to the lower ends of the two triangular fixing frames, the upper screws and lower screws are connected through sleeves, a square sleeve is fixed to the lower end of each lower screw, and a rigid scraper penetrates into the square sleeves at the lower ends of the two lower screws. The system has the advantage of ensuring gradient control of the filling surface of the tunnel inverted arch.

Description

Technical field: [0001] The invention relates to a scraper system used for leveling the filling surface of an inverted arch of a tunnel. Background technique: [0002] With the rapid development of highway, railway and other building construction in our country, there are more and more tunnel projects. In the construction of tunnel projects, the quality control requirements for inverted arches are getting higher and higher. Manual operation has large errors and cannot effectively control the slope. Due to the narrow working space between the top surface of the inverted arch and the trestle bridge, it is difficult to level and slope the top surface of the inverted arch, and it is impossible to perform effective slope closing. It is difficult to control the slope of the inverted arch of the tunnel, resulting in water accumulation in the tunnel along the slope, which cannot be guaranteed Civilized construction requires rework or processing in the later stage, which increases c...

The manual operation error is large, and the slope cannot be effectively controlled

Due to the narrow working space between the top surface of the inverted arch and the trestle bridge, it is difficult to level and slope the top surface of the inverted arch, and it is impossible to perform effective slope closing. It is difficult to control the slope of the inverted arch of the tunnel, resulting in water accumulation in the tunnel along the slope, which cannot be guaranteed Civilized construction requires rework or processing in the later stage, which increases costs
