Description
Technical field
The present invention relates to railway concrete sleeper building field, more particularly to a kind of anchorage mortar and its application method.
Background technology
Railway track is to be fixed on by screw spike and nut through elastic bar fastener on sleeper, and screw spike is to use Anchor Agent anchor
It is fixed in sleeper nail, an entirety is formed with sleeper.
At present, the Anchor Agent applied to screw spike anchoring has Sulphur concrete Anchor Agent, the Anchor Agent of resinae and common
Mortar type Anchor Agent etc..What China's screw spike anchoring was most widely used is to use Sulphur concrete Anchor Agent.Sulphur concrete anchor
Gu agent is by certain proportioning by sulphur, cement, sand and paraffin etc., boils by being heated to 140 DEG C -160 DEG C and form.It has
The characteristics of price is relatively cheap, curing rate is fast, good insulating.But also there is pollution is big (to be produced when boiling and largely contain sulfide
Dense smoke, pollution environment damages the health of workmen simultaneously, some countries because sulfur cement mortar anchorage agent not environmentally the reason for
Prohibit the use of), the defects of anchor force limited (general withdrawal resistance is less than 70KN), complicated construction technique.Other sulphur can be in sky
Oxidation generation sulfuric acid in gas, cause corrosion of the railway spike with anchoring interface to peel off or even be broken, have a strong impact on traffic safety.Also exist
The temperature of Sulphur concrete Anchor Agent is very high during anchoring, and sleeper reserves the shock heating chilling of internal surface of hole when causing to anchor, and heat expansion is cold
Internal stress caused by contracting can destroy sleeper preformed hole inner surface structure.When screw spike is by external force such as locomotive load, sleeper
Concrete structure is highly prone to secondary destruction, very unfavorable the extraction-resistant behavior sleeper/screw spike.In addition, Sulphur concrete
Anchor Agent can shrink during cooling and solidifying, and this will also result in the problem of anchor force is not strong, particularly to smooth interior table
The anchoring effect in face hole is very poor.
Also the Anchor Agent with resinae, such as epoxy resin, polyurethane resin etc. are had been reported that.When this kind of Anchor Agent uses pair
Interfacial cleanliness degree requires very high, can not such as have dust adhesion, surface must be dried, it is impossible to the presence of moisture etc., otherwise withdrawal resistance
It will be influenceed by very big.And can typically use the instruments such as water drilling to carry out punch operation during due to repairing, it can typically drilled out
Hole in remain a large amount of cement mortars and ponding, even if at once carry out borehole cleaning operation, it is also difficult to reach the Anchor Agent pair of resinae
The cleanliness factor and degree of wetting of bonding interface requirement；If carrying out anchoring operation with this kind of material by force, interfacial adhesion can be caused
Intensity and withdrawal resistance are not enough so as to leaving potential safety hazard.This kind of material is expensive in addition, it is difficult to promotes the use of a large area.
Ordinary mortar type Anchor Agent setting time is partially slow, and early strength is relatively low, it is impossible to which quick-drying is fast strong, it is necessary to carry out for a long time
Maintenance get to some strength, withdrawal resistance could meet the 60KN of iron mark requirement；And in high-speed railway regular maintenance, by
There was only trivial 5 hours or so in the time window for leaving maintenance and repairing for, then will open to traffic.And share anchoring operation
Period often there was only 2 hours or so, what general cement class material had little time that solidification reaches requirement at all is more than 60KN resistance to pluckings
Intensity.The Chinese patent of Application No. 200810100968.6 discloses a kind of quick grouting available for railway bridge bearing
Material, its two hours compression strength are also only only above 20MPa, it is impossible to meet to want early stage high intensity during railway recovery operation
Ask.

The moist insulaion resistance index of 120 megaohms of road Industry code requirements is differed greatly, and rail is anchored using ordinary mortar type Anchor Agent
Screw spike is rested the head on, because its is on-insulated, rail track can be caused conductive, so as to produce red band, so that signal of communication is lost, danger
And traffic safety, produce traffic safety accident.As Chinese patent " B of CN 101508547 " discloses a kind of fragment-free railway
Plate early-strong-fast-hard end capping anchorage mortar material, though this anchorage mortar material has, early strengthening and high strengthening, cracking resistance be impervious, high bonding
The performances such as power, low chlorine ion content, but be not directed to and solve the problems, such as ordinary mortar insulating properties deficiency, thus it is applied to railway spike
Certainty entail dangers to traffic safety during anchoring.In addition, the Chinese patent of Application No. 200910131850.4 discloses a kind of high speed
Railway bridge bearing anchorage mortar material, it is improved in terms of the durability and cost of mortar, but still is not solved and be applied to
The problem of insulating properties deficiency of the mortar of railroad spike anchoring.
