Abstract
The invention relates to a high-strength drilling anchoring agent and is suitable for various building projects requiring higher durability such as large-tonnage anchor rods, anchor cables and tail anchorage of equipment. The high-strength drilling anchoring agent is mainly formed by the mixture of powder mainly consisting of silicate minerals; volcanic ash activated powder, coal ashes or slag or silicon powder, reduced and contracted activated powder, sulphoaluminate minerals; reduced and contracted inert particles, surfactants, naphthalenesulfonic formaldehyde condensation compound, sulfate, amine, retarders, salt calcium or ignosulfonate and water retaining agent and cellulose ethers. The high-strength drilling anchoring agent is characterized by long operation time, no toxicity or harm to human and environment, high early strength, stable development of later strength, strong erosion-resistance and high durability.
Description
Technical field
The present invention relates to a kind of be adapted to various underground workss, danger high slope, engineering in repairing bolt anchorage and equipment install in protection, repairing and the filleting when repairing and the high-strength borehole anchorage agent of slip casting of wash surface of lower margin, Equipment Foundations back-grouting and concrete structure.
Technical background
Anchor pole in underground works, danger high slope rock mass reinforcing and the engineering reparation and equipment are installed lower margin, Equipment Foundations back-grouting etc. all needs to adopt suitable anchoring or injecting paste material, but general cement based anchoring or drawback such as injecting paste material ubiquity material cured is slow, early strength is low, contraction is big, stretch-draw length of time is long, anchoring strength is low.
Summary of the invention
Purpose of the present invention is exactly that a kind of good anchoring and injection material of strong, high-strength anchoring property early that have will be provided, and is particularly suitable as large-tonnage anchoring material, injecting paste material and concrete repair material in the underground works higher to life requirement, that running environment is abominable, danger high slope, the engineering reparation.
The object of the present invention is achieved like this: a kind of high-strength borehole anchorage agent is mixed by following component, in weight part: 38～67 parts of silicate minerals powders; Pozzolanic activity powder: 13～33 parts; Reduce the active powder that shrinks: 4～6 parts; 0～43 part of the inert particle that reduction is shunk; Tensio-active agent: 0.5～2.5 part; Retardant: 0.2～0.3 part and water-holding agent 0.2～0.5.
Described silicate minerals is for mainly containing the mineral of tricalcium silicate, Dicalcium Phosphate (Feed Grade).
Described pozzolanic activity powder is flyash or slag or silica flour.
Reducing the active powder that shrinks is the mineral that mainly contain anhydrous calcium sulphoaluminate.
Reducing the active powder that shrinks is sulphoaluminate phase.
Reducing the inert particle of shrinking is silicon oxide.
Described surfactivity is agent naphthalenesulfonate formaldehyde condensation compound or vitriol or amine tensio-active agent.
Described retardant is sugared calcium or sulfonated lignin.
Described water-holding agent is an ether of cellulose.
High-strength borehole anchorage agent provided by the present invention, silicate minerals provides intensity; The pozzolanic activity powder improves the flowability of slurry, continues to increase later strength simultaneously; Reducing the active powder that shrinks is expansion component; Inert particle can reduce slurry contraction; Water-holding agent can reduce the slurry segregation, reduce moisture evaporation and reduce slurry contraction; Tensio-active agent is to reduce water-cement ratio, to improve early strength and regulate time of coagulation.Product have the material cured time suitable, early strength is high, later strength development, do not have shrink, stretch-draw length of time is short, anchoring strength is high characteristics, can satisfy the demand of large-tonnage anchor pole, anchor cable and the rapid construction of equipment lower margin, high anchoring strength.
