Embodiment Construction

[0023] A new method for rough adjustment of double-block rail rows. The specific construction steps are as follows: a. Place the laser pointing track ruler on a group of rail rows 9 that have been fine-tuned, and install prisms on the finely adjusted rail row beams. There is a cross line on the prism and a scale on the line, adjust the laser pointing track ruler to make it perpendicular to the rail of the rail row 9;

[0024] Such as figure 1 As shown, the laser pointing track ruler 10 includes a digital display track ruler 1 arranged on the rail row 9 and perpendicular to the rail row 9. One end of the digital display track ruler 1 is provided with a fixed end 4, and the digital display track ruler 1 is provided with a fixed end 4. 1 The other end is provided with a movable end 5, the fixed end 4 and the movable end 1 are respectively stuck on the inner sides of the rails on both sides, the digital display track ruler 1 is fixed with a rotating mechanism 2, and the rotating m...

Abstract

The invention belongs to a track panel coarse adjustment method, and particularly relates to a novel double-block type track panel coarse adjustment method. The method solves the problems that the center line of a double-block type ballastless track construction coarse adjustment line is accurately marked and is unlikely to be observed and the requirements for light rays and construction personnel quality are high; a track panel is coarsely adjusted, so that the problems that the center line of the line is unclearly and inaccurately marked in existing track panel method construction, time and labor are wasted for hanging a plumb bob and the plumb bob is unlikely to be observed. The arrangement and coarse adjustment of the track panel are merged into one working procedure, and the precision in the track panel arrangement period can reach the precision after coarse adjustment, so that the coarse adjustment working procedure is reduced, and the time used for coarse adjustment is reduced.

Description

technical field [0001] The invention belongs to a method for rough adjustment of a rail row, in particular to a novel double-block type rough adjustment method for a rail row. Background technique [0002] In recent years, the use of rail row method has become the main construction method of double-block ballastless track. The rail row comprises two steel rails arranged in parallel, and four beams arranged perpendicular to the rails on the rails. The construction method used in the rough adjustment of the center line of the rail row method is: hang the vertical ball on the marked center line on the rail row beam, and use the installed rail direction locker to adjust the rail direction and the rail row center line, so that the rail row The centerline of the beam structure coincides with the centerline of the line. This kind of operation requires that the center line of the line be drawn accurately and is not easy to observe, and has high requirements on the quality of light...
