Description
Technical field
The present invention relates to a kind of quick reparation injection material of building material engineering technical field, specifically a kind of high ferro ballastless track mortar layer that is used for repairs grout and mortar fast.
Background technology
Along with greatly developing of China Express Railway, non-fragment orbit is widely used.Although it is a little a series of that non-fragment orbit has high smooth-going, high stability etc., under train load and environmental factors, non-fragment orbit inevitably produces some diseases, and these damages have had a strong impact on the safe operation of high ferro.By carrying out Tracking investigation to existing high ferro non-fragment orbit running condition, find that screed becomes the most common and main a kind of damage mode.For this special structure of high ferro, due to train operation can not discontinuity, for patching material, there is following special performance requriements: 1. Window time is shorter, must realize being open to traffic in general 4h; 2. there is higher mobility; 3. good cohesive strength and toughness.
At present, for the material that high ferro ballastless track mortar layer is repaired fast, two classes are mainly contained.The first kind is mineral-type, mainly contains quick-setting cement mortar and cement-emulsified asphalt material.These two kinds of inorganic materials also exist some defects: the cohesive strength of rapid hardening cement is lower, and self-strength is not high, is mainly used in the maintenance of non-stress concrete defect, once use in force part, easily cause secondary hurt.Erosion resistance and the freeze-thaw resistance of cement emulsified asphalt mortar are poor, and after maintenance, 3-5 there will be secondary hurt in various degree.The organic polymer slurry that Equations of The Second Kind is formed with epoxy resin, Vinylite, isobutylene resin, they have good mechanical property and to concrete excellent bond performance, but they also also exist some intrinsic defects, such as problem of aging, execution conditions complexity and cost intensive etc.By the literature search to prior art, yet there are no relevant special in high ferro ballastless track mortar layer material for quickly repairing,
Summary of the invention
For defect of the prior art, the object of this invention is to provide one and repair grout and mortar fast for high ferro ballastless track mortar layer, it has the early strength of superelevation, and 1h ultimate compression strength reaches more than 30MPa, has excellent cohesive strength and good toughness with old sand pulp layer.
