Problems solved by technology

But this method must be approved by the railway bureau and the transportation department, and the railway transportation is very busy now, it is almost impossible to realize
Another method is to fix and lock the turnout with the approval of the railway bureau and the transportation department, and only open to the straight strand. It requires a special D-shaped beam, which is difficult to reinforce and has high construction risks

Example Embodiment

[0023] The technical solution claimed by the present invention will be described in detail with reference to the drawings.

[0024] 1. Manually pierce the steel beam and move the D-shaped steel convenient beam

[0025] Because square concrete turnout sleepers are not needed in the turnout area, and the sleeper spacing cannot be squared and adjusted in advance, the steel beam 2 is inserted in the middle of the turnout sleepers directly according to the coordinate position of the steel beam. Manually move the D-shaped steel temporary beam 1, and set up a beam-moving platform on the outside of the existing shoulder in advance. The beam-moving platform must be firm and the height cannot exceed the rail top elevation; two D-shaped steel temporary beams 3.5 meters away from the two ends The steel rail slideway uses the standard gauge large pulley on the railway to horizontally move the D-shaped steel convenient beam 1; when entering the beam, advance a beam in the middle of the strand, a...

Abstract

The invention relates to a construction method for jacking in a turnout zone, in particular to a construction method for reinforcing the turnout zone of a criss-cross I-shaped steel and D beam combination system. Without the need for changing traffic organization and dismantling turnout equipment, lines between turnouts are strengthened, the normal positioning, steering and use of the turnouts arenot affected, and the normal transportation operation of a station is greatly guaranteed. Compared with a conventional construction method, the method is applicable to the reinforcement of the turnout zone, applicable to the reinforcement of the lines, and high in safety and stability. The operation of an existing railway is not affected, the operation organization of an existing railway stationis changed, and the railway transportation is affected little. The demolition of existing equipment and the demolition project volume can be reduced, and various working conditions which are not complete by conventional construction methods can be completed. Each share road only needs a short time to break the railway operation , the operation is convenient, the construction cost is low, and the effect of construction on the railway operation can be minimized.

Description

technical field [0001] The invention relates to a jacking construction method for a turnout area, in particular to a construction method for reinforcing a turnout area with a combined system of vertical and horizontal I-beams and D beams. This method researches the need to change the driving structure and dismantle the turnout equipment. The line between the turnouts is reinforced without affecting the normal positioning, turning and use of the turnouts, which greatly guarantees the normal transportation operations of the station. This method has the advantages of less blocking points, no change of the station traffic organization, no need to block power outages, and low construction costs. Wide adaptability and other characteristics. Background technique [0002] Construction sites for jacking bridges and culverts on existing railway lines are generally selected in interval lines, and should not be located in hub stations, tunnel entrances, turnout areas, road-bridge transi...
