Abstract

The invention discloses a construction method for integrally realizing a double-sided paper rolling slope of a paper machine, and relates to the technical field of paper making. The construction method comprises the following steps that a paper rolling slope area is delimited, plate penetrating bolts are arranged, a central plate penetrating bolt positioned at the central position and edge plate penetrating bolts positioned at the farthest ends of the left and right sides are marked, the highest point and the lowest point of a longitudinal slope surface are marked, and the lowest point of the transverse slope is marked; preliminary positioning is carried out; finally positioning is carried out; and an edge closing baffle is arranged, concrete is poured into the paper rolling slope area to form a slope surface prototype, leveling is carried out by using a scraper, and the slope surface is maintained. The construction method for the double-sided paper rolling slope of the paper machine is time-saving, labor-saving, simple, controllable and good in laying effect, ensures the consistency of gradients on the two sides of the double-sided paper rolling slope, ensures the engineering quality, further solves the problem of one-time pouring of bidirectional gradients, is time-saving and labor-saving, and is simple and controllable; and meanwhile, it is ensured that the error range of the slope flatness of the paper rolling slope is controlled within +/-1 mm, and the effect is remarkable.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a construction method for integrally realizing double-sided rolling paper slopes of a paper machine. Background technique [0002] In the field of papermaking technology, after the paper roll is produced by the paper machine, it needs to be transported, and there is a height difference between the outlet of the paper machine and the floor, so it is necessary to specially design a rolling paper slope area to guide the produced paper roll to roll directly To the paper loading area, it is convenient to concentrate the paper rolls. Because in actual construction, it is difficult to control the angle of the slope. In the existing technology, the design method of single-sided slope is mostly used. For the construction of double-sided paper rolling slope Programs are rare. In addition, the flatness design standard of the overall concrete surface is ±5mm, but in the actual construct...
