Existing line transverse lifting strengthening method and structure

Abstract

The invention discloses an existing line transverse lifting strengthening method and an existing line transverse lifting strengthening structure. Different from the conventional line straightening method requiring bed timber replacing and track locking, the method adopts a construction process which uses 'III'-shaped steel beams as longitudinal beams and uses I25 I-beams to perform the transverse lifting strengthening of the existing lines. The method has the advantages that: a connecting fastener is simple and consumes less material; the lines are strengthened directly, so the influences on the line rigidity and the like are light; working procedures are reduced, time is saved, and at least two window long time for replacing bed timbers and locking tracks can be saved, wherein one window is saved each day, and each window represents 1.5 hours; and the safety and quality are ensured.

Description

technical field [0001] The invention relates to a method and structure for horizontal lifting and strengthening of existing lines. It belongs to the horizontal lift reinforcement construction technology for existing lines. Background technique [0002] In the reconstruction of existing operating lines or the construction of adding culverts, line reinforcement is the key to jacking construction. In the past, the method of pumping concrete sleepers for wooden sleepers and buckling suspension rails was often used for reinforcement. The disadvantage is that firstly, it requires replacing sleepers and making beam beams, which requires a lot of materials; secondly, the construction period is long, which is not conducive to the operation of existing lines; thirdly More manpower is invested, resulting in increased costs. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide a method and structure for horizontally lift...
