Abstract
The invention relates to the field of railway concrete sleeper construction, particularly an anchoring mortar and an application method thereof. The anchoring mortar comprises 20-50 parts by weight of sulfoaluminate cement, 30-70 parts by weight of dry sand and 5-15 parts by weight of expanding agent. Compared with ordinary Portland cement, the setting speed of the anchoring mortar is much higher, the compression strength can reach to more than 25 MPa within one hour, and even more than 50 MPa in summer. When the anchoring mortar is used on a highway, the highway can be opened after one hour, thereby enhancing the construction quality and reducing the traffic jams. When being used for construction and emergency repair of concrete structures in the fields of airports, highways, municipal engineering and the like, the anchoring mortar can greatly shorten the construction period, so that the concrete structures can be used in advance.
Description
Technical field
The present invention relates to railway concrete sleeper building field, relate in particular to a kind of mortar and method of use thereof that is used for anchoring.
Background technology
Sulphur concrete anchoring agent is generally used in the anchoring that is used for railway concrete sleeper screw spike.It is that sulphur-cement-sand and paraffin boil through high temperature and forms.It has cheaply, curing speed characteristics such as be exceedingly fast.Pollute big (country that has should be the environmental protection reason and forbids its use) but also have, inconvenient operation, the limited defectives such as (general withdrawal resistance are less than 70KN) of anchor force.Sulphur can oxidation generate sulfuric acid in air in addition, causes the corrosion even the fracture of spike anchor and liquid/solid interface.The temperature of Sulphur concrete anchoring agent is very high when anchoring in addition, can cause sleeper pocket internal surface minimal stress to destroy owing to expand with heat and contract with cold, and the destruction of sleeper concrete structure when this has increased the drawing bolt is very unfavorable to improving sleeper/bolt withdrawal resistance.In addition, Sulphur concrete anchoring agent is to shrink to some extent at cooling curing, and this also can cause the not strong problem of anchor force, and is particularly very poor to the anchoring effect of slippery inner surface hole.
The anchoring agent of report with resene also arranged, like epoxy resin, urethane resin or the like.This type anchoring agent quick solidifying, anchor force is strong, but very high to the requirement of interface cleanliness factor, and as dust adhesion can not be arranged, the surface must be dry, can not have moisture to exist or the like.Costing an arm and a leg of this type material is difficult to big area and promotes the use of in addition.
The curing speed of general cement class anchoring agent is too slow, generally takes more than 1 day and could solidify and have certain intensity.This is unfavorable to construction of railways, particularly to first-aid repair construction.
Especially in the high-speed railway routine maintenance, have only trivial about 5 hours owing to leave the time window of maintenance and repairing for, then will open to traffic.And the time period of sharing the anchoring operation often had only about 2 hours, and general cement class material has little time to solidify at all and meets the requirements of the pulling test strength greater than 60KN.And because repairing the time generally can make instrument such as water brill carry out punch operation; Generally can be in the hole that is come outbreak out residual have a large amount of grouts and ponding; Even at once carry out hole operation clearly, also be difficult to reach cleanliness factor and degree of wetting that the anchoring agent of resene requires bonding interface; If use this type material to carry out the anchoring operation by force, thereby can cause interface binding intensity and withdrawal resistance to stay potential safety hazard inadequately.
Summary of the invention
The object of the present invention is to provide a kind of mortar and method of use thereof that is used for anchoring, solve the not enough problem of existing anchorage mortar constant intensity.
For addressing the above problem, the technical scheme that the present invention taked is:
