Description
Technical field
The present invention relates to a kind of quick-setting early strength cement-silicate double solution grouting material and its application methods, are suitable for mine
The pre-grouting of tunnel broken top plate is reinforced, and mine and underground engineering security technology area are belonged to.
Background technique
The exploitation of mineral resources is that human society advances and a developing important component, it is to human society
Development and the progress of civilization have important impetus.The state of country rock is stability of the roadway after the property and tunnel initating of country rock
An important factor for.Quite a few in country rock high stress is caused by excavation, can be undertaken by country rock itself.Once rock mass is destroyed
And intensity is lost, it not only can't be the ballast in tunnel, can become the load of supporting instead.In many mining area coals in China
Mine can encounter that lumpiness is smaller, roadway surrounding rock in loose crushing shape during exploiting, in the coal seam acted on by mining induced stress
Or digging laneway in breaking surrounding rock, discrete coal seam or rock mass equilibrium state in original equilibrium state are destroyed, lane
Road country rock causes plane of weakness to further expand, new crack generation because deformation discharges big energy, broken so as to cause wall rock loosening
It is broken.According to unsuitable maintenance measure, it will cause roadway surrounding rock crack and more develop, supporting difficulty increases, and eventually leads to lane
Road destroys；Roadway surrounding rock after destruction is more broken, and regeneration crack is more developed, and brings bigger difficulty to roadway maintenance.
In China, there are small kiln destruction areas for many coal mines, and when exploiting to lower leaf, most of coal seam is broken by small kiln
Bad, roof is broken after coal seam higher slice is destroyed by small kiln is caving, and partial region be located at old coal pit goaf stay set it is narrow
Under coal column, so that roof rock is caving significantly affecting for the stress concentration region to be formed by goaf around, exploitation difficulty is caused
Increase.Breaking surrounding rock grouting and reinforcing, be the various planes of weakness of country rock are enriched using slurries, re-start it is cementing, to mention
High country rock overall stability and mechanical property, enhance the self-bearing ability of country rock, participate in the further equilibrium process in tunnel.Country rock note
Slurry, which is reinforced, often to be combined with other roadway support forms, it not only improves rock property lithology and stress distribution, but also
Deformation of the surrounding rock in tunnel is greatly reduced, to substantially improve the force-bearing situation of other support forms.But cement base is mostly used at present
Class injecting paste material, such injecting paste material setting time is long, intensity is increased slow, and tunnel is in a short time after being unfavorable for grouting and reinforcing
Driving, causes coal mine excavation engineering to take over anxiety.
In conclusion need to research and develop a kind of quick-setting early strength cement-silicate double solution grouting material, it can be in the short time after slip casting
The interior Seed harvest for forming high intensity prevents the generation of tunnelling roof fall accident to guarantee the stability of roof cracking country rock, can
Guarantee the safety of tunnelling and working face equipment installation, the safety and high efficiency for modern mine provides safeguard.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the present invention provides a kind of quick-setting early strength cement-water glass
Glass dual-liquid slip-casting material and its application method, the injecting paste material is with setting time is short, early strength is high, calculus rate is high, pumpable
The feature that property is good, stability is good.
Technical solution: to achieve the above object, the technical solution adopted by the present invention are as follows:
A kind of quick-setting early strength cement-silicate double solution grouting material, including matrix component mix component, matrix component packet with outer
Cementitious material is included, mixing component outside includes accelerator and water-reducing agent；The cementitious material is used for cementing breaking surrounding rock, and accelerator is used for
Accelerate the rate of set of cementitious material hydration reaction, water-reducing agent is used to reduce unit consumption of water and improves the workability of slurry.
Preferably, the cementitious material in the injecting paste material and mix outside accelerator in component proportion it is as follows: mix according to the ratio
It closes cementitious material and water and carries out mechanical stirring formation mixed slurry, the volume ratio of mixed slurry and accelerator is 0.9~1.1:
1；
Cementitious material in the injecting paste material and the proportion for mixing water-reducing agent in component outside are as follows: the quality of water-reducing agent is glue
The 1.0~3.0% of gel material.
Preferably, the cementitious material is ordinary portland cement (marked as PO 32.5~42.5), accelerator 10
(accelerator can accelerate the hydration reaction of cementitious material to the water glass solution of~17 ° of Be', be rapidly achieved initial setting strength, improve lane
Strength and stability after road breaking roof is cementing, the generation of roof fall accident when preventing tunnelling guarantee tunnelling peace
Entirely), water-reducing agent is naphthalene series high-efficiency water-reducing agent.
A kind of above-mentioned quick-setting early strength cement-silicate double solution grouting materials'use method, includes following steps:
Step 1: pouring into cementitious material, water and water-reducing agent in blender be uniformly mixed according to the ratio, forms matrix mixing
Body；
Step 2: configuring water glass solution according to the ratio, then stirs evenly water glass solution with matrix mixture to be formed
Cement-water glass double grouting material；
Step 3: cement-water glass double grouting transport of materials is carried out into tunnel by grouting pump and high-pressure hose
Filling；
Specifically, the mass ratio of water and cementitious material is 0.3~0.5:1 in the step 1.
The utility model has the advantages that quick-setting early strength cement provided by the invention-silicate double solution grouting material, using matrix component (glue
Gel material, water) and it mixes component (accelerator, water-reducing agent) outside and is formulated, which has that setting time is short, early strength
Feature high, calculus rate is high, pumpability is good, stability is good；It, can be in the short time after slip casting using application method provided by the invention
It is mined out can preferably to solve the old kiln in second mining tunnel to guarantee the stabilization of roof cracking country rock for the interior Seed harvest for forming high intensity
Area and little Lao Yao coal column area roof cracking problem, are conducive to roadway surrounding rock stability contorting.
Specific embodiment
Below with reference to embodiment, the present invention will be further explained.
A kind of quick-setting early strength cement-silicate double solution grouting material, including matrix component and mix group outside and be divided into two parts, wherein
Matrix component be include cementitious material and water, mix group outside and be divided into including accelerator and water-reducing agent.
The cementitious material is common P.0 32.5~42.5R portland cement；The water-reducing agent subtracts for naphthalene series high-efficiency
Aqua, quality are the 1.0~3.0% of cementitious material；The accelerator is the water glass solution of 10~17 ° of Be', accelerator
