Abstract

The invention relates to preparation and a construction method of a grouting material (referred to as RE-GD) for track filling and secondary grouting. The RE-GD comprises three components, A, B and C. The component A is a modified epoxy resin mixing system, which comprises modified epoxy resin, an active diluent, a toughening agent, an antioxidant, a leveling agent, a defoaming agent and a coupling agent. The component B is a curing agent. The component C is a filler. The high-strength precise non-contraction epoxy resin grouting material for tracking provided by the invention has the advantages of high adhesion to a cement base and a steel base, high strength, good toughness, no expansion, extremely low contraction rate and small amount of dense porosity; excellent properties of polymer material enables the material with characteristics, unmatched by other materials, in corrosion resistance and weatherability performance, and can satisfy usage in different climate environment. The material provided by the invention has long cycle of usage and a general service life of up to 30 years, and can be used as a substitute or be applied to environment and position, which CA mortar or cement base grouting material can not be applied to.

Description

technical field

[0001] The invention relates to a preparation and construction method of epoxy grouting material for track filling and secondary grouting. Background technique

[0002] Railway container transportation is an important symbol of railway freight modernization. In recent years, the container transportation industry at railway ports has developed rapidly, and the transportation volume has increased significantly. However, problems such as backward facilities for reloading containers on railways and insufficient capacity have become increasingly prominent. The existing track system has seriously affected production and brought safety hazards to crane operations.

[0003] In order to make the slab track have a certain degree of elasticity, reduce the construction error of the base, and fix the position of the track structure, it is usually necessary to fill the non-shrinkage buffer with excellent toughness and adhesion between the concrete base (or steel structure...
