Abstract
Anchoring agent of the present invention is to be that an amount of adulterating agent cooperation of main raw adding forms with unslaked lime.The effect of adulterating agent mainly is to delay the calcium oxide hydration reaction time before anchoring agent roll immersion filling, strengthens the expansion character and the setting strength of hydrated reaction product behind filling hole.Because the dual use of extruding of condensing and expand of hydrated product has very strong cohesive strength and friction resistance, and anchor force is reached more than 6 tons.And longterm strength does not descend.The proportioning of regulating adulterating agent also can improve early stage anchor force.
Description
The present invention is relevant with bolt supporting, and is especially relevant with the anchoring agent.
Bolt supporting is a kind of form of roadway support, at home and abroad is used widely.In order to guarantee the anchor force of anchor pole, people have made big quantity research to the anchoring agent.Adopt resin to do the anchoring agent of anchor pole, to a certain degree solved the integrity problem of anchoring.But because resin anchoring agent price height, inflammable, toxic and easy problem such as wear out has hindered promoting the use of of it.In recent years, begin to replace the use of resin anchoring agent with rapid hardening cement, ore deposit, Xi'an institute, China ore deposit institute develops the double-quick cement volume respectively and expansive cement is rolled up two kinds of anchoring agent, have easy to operate, the reliable superiority of anchoring, but because cost is higher, need specialized factory or specific equipment production, shortcomings such as source of goods inconvenience have hindered its popularization.
The purpose of this invention is to provide a kind of convenience of drawing materials, fixing agent for anchor poles with low cost, easy to use, that anchor force is strong.
The present invention is achieved in that
The present invention is by calcium oxide, and the water reducer powder is formed, and its consumption is as follows: weight %
Calcium oxide 85-90
Water reducer 2-15
Another kind of prescription of the present invention is by calcium oxide, water reducer, and solid water glass, cement is formed, and its consumption is as follows: weight %.
Calcium oxide 60-90
Water reducer 1-5
Solid water glass 3-10
Cement 6-30
The composition powder bag that the water-permeable flexible material makes of packing into is made volume, and water cement ratio is not less than 0.25 during use.
Calcium oxide is a particulate state, and particle size range 1-7mm, its average particle size are 3.5mm, and water reducer is wooden calcium water reducer, and cement is ordinary slag cement.
The long strip shape that the volume cover is made for macrofiber filter paper, its packing density is 1.45g/CM3, water cement ratio is 0.25-3 when using.
Stab several apertures with tingle on volume during use, 10-20 is about to batch out skyhook in the eye of packing in the immersion water after second.
After the immersion, calcium oxide promptly produces hydration reaction.For hydration reaction is strengthened behind the skyhook in package is pleasing to the eye again, need additive to delay hydration reaction time.Water reducer, water glass powder, cement all can work to delay hydration reaction time.Calcium oxide is met water generation hydration reaction and is produced a large amount of heat, and the water glass powder is molten for aqueous, is attached to the calcium oxide particle surface and forms gluey coating, makes calcium oxide for some time sluggish in early days.Because along with the swelling property of reaction big calorimetric of generation and reactive material, the glued membrane integument on calcium oxide particle surface is squeezed broken, the calcium oxide hydration reaction quickens.Become loose powdery after the calcium oxide aquation, cooled water glass condenses it fastening.Cement can be filled oxidation hydrated product particle gap, strengthens set strength.If required early stage anchor force is not too big, available calcium oxide and water reducer are formed composition, and water reducer rises in early days and delays the hydration reaction time use, along with the increase in reaction times, can strengthen anchor force later on.
The present invention is owing to have the extruding dual function of condensing and expand, and cohesive strength and friction resistance are all very high.Just can reach enough intensity at short notice.The ground simulation test is installed the back anchor pole that can make 14 mm dias in 5 minutes of the volume anchor force that reaches capacity, and keeps anchoring strength for a long time.Furong Mine Administration Bureau Xun Chang colliery is facts have proved that volume surplus the present invention 480,000 is used for that use in meter tunnel surplus in the of 10,000, the present invention have early coagulate, fast hard, characteristics that expansion strength is high, after 5-15 minute, can reach anchor force more than 6 tons.Its force pulling and early strength all are better than double-quick cement volume anchor pole and expansive cement volume anchor pole.And price only be respectively the former 0.12 and the latter about 0.28.And traditional cement volume needs specialized factory, produces with specific equipment.Because user's consumption is few, the cement storage time again can damp failure after for a long time, so tissue supply is relatively more difficult.Calcium oxide component of the present invention is available anywhere, and only needs to purchase dopant in market, and artificial mix is used very convenient by a certain percentage.
Following is embodiments of the invention:

In above embodiment, water reducer is all wooden calcium water reducer, and cement is all the 425# slag cement.The calcium oxide particle diameter range is 1-7mm.The volume bag is the long strip shape paper bag that the bigger macrofiber filter paper of wet strength makes 240mm, and diameter is 37mm.Each the paper bag dress present composition 300 gram, the about 1.45 gram/CM3 of packing density.Stab several apertures with tingle during installation on paper bag and immerse 10-20 second in the water, its water cement ratio is 0.25-3.
Following is performance test report of the present invention:
Anchor pole later strength trial report
