Embodiment Construction

[0020] Combined with the accompanying drawings, the production process of the two-way long-line pedestal method is described in detail. The specific production steps are:

[0021] 1 Model cleaning Clean the track plate mold, side plate, and end plate. When cleaning ash and dirt, it is strictly forbidden to hammer or hit directly with hard objects to avoid pits and local deformation.

[0022] 2 Mold positioning Move the steel mold to the positioning position, insert the positioning pin, the movable end beams 2-1, 2-2 are horizontally restored to the position before stretching, and the tensioning device is adjusted to the state before tensioning.

[0023] 3. Spraying the release agent should be evenly sprayed to prevent missing coating, and not too much. Use a sponge to wipe off the accumulation of the release agent for a long time, so as not to see obvious oil stains. The side plates, end plates, and arcs can be painted with a brush.

[0024] 4 Lay out the prestressed tendons S...

Abstract

The invention relates to a two-way long-line pedestal method production process of a prestressed concrete track slab. The invention discloses the two-way long-line pedestal method production process of the prestressed concrete track slab, which comprises relevant equipment and concrete production flows. The invention solves the problems of stretching and loosening of a two-way pretensioning track slab, enables molds to be continuously arranged tightly in both a longitudinal direction and a transverse direction and realizes the batch production of the two-way pretensioning track slab.

Description

technical field [0001] The invention relates to the field of production of ballastless track slabs for high-speed railways, in particular to the field of production of pretensioned track slabs. Background technique [0002] Domestic high-speed railways have been developing rapidly. Generally speaking, compared with foreign countries, they started relatively late, with little experience and a weak foundation; currently, in the overall layout, the Beijing-Tianjin Line II-type slabs are mass-produced, and the one-way long lines are adopted. Pedestal production process, horizontal pre-tensioning, a set of production lines can produce 27 track slabs at a time. There is no report on the use of long-line pedestals for I-type plates at home and abroad. Contents of the invention [0003] The purpose of the present invention is to solve the problem of mutual interference in the vertical and horizontal directions existing in two-way stretching, and the problem of mold precision [...
