Description
Technical field:
The invention belongs to soundless cracking technical field, be specifically related to a kind of underwater static fracturing agent and
Its preparation method, is introduced to static crushing technology in underwater performance, it is achieved Underwater Engineering quiet
State crushes.
Background technology:
Static crushing technology is a kind of new fractured rock and concrete that development in recent years is got up
Method, be static breaking agent is coordinated plus appropriate water after inject in big gun hole, by broken
Agent self occur hydration reaction produce volumetric expansion, thus slowly, quietly by the bulbs of pressure
It is applied to hole wall, medium is crushed；The static breaking agent used has another name called soundless cracking agent, its
In name republic building material industry standard of China " soundless cracking agent " (standard No. JC506-2008)
Defined in be " all through the high-temperature calcination inorganic compound based on calcium oxide, mix appropriate outside
Add the broken pulverulent material of non-explosion with highly expanded performance that agent intergrinding is made ",
Do not produce public hazards due to it, can implement quick-fried reliably at the restricted place safety of explosive blasting
Broken, and in cities and towns, the various occasions such as Factory Building, machine, equipment are widely applied.Existing
Static breaking agent many employings calcium oxide in technology, paraffin, Extend position etc. are main component,
Such as disclosed in Chinese patent ZL201310368514.8 a kind of coordinate that hidden hole drilling uses quiet
State cracking agent, a kind of static breaking agent disclosed in Chinese patent ZL201410039857.4, in
The compositions of a kind of static breaking agent disclosed in state's patent ZL201110348685.5, China is specially
Open a kind of static breaking agent of profit ZL200910090695.6 etc., all cannot realize in water
Irrigate and do not disperse to produce powerful expansive force, and Chinese patent ZL99116548.9 is open
A kind of static breaking agent and manufacture method, although composition is improved, in quick lime
Add FeCl ↓ [3] and cement, but be still difficult to produce a desired effect；And put into practice at present
In, underwater concrete crushes the method for employing and is the most still explosion, hydraulic drill, pneumatic pick, cuts
The traditional power method such as cut, therefore to static crushing technology is introduced in Underwater Engineering project,
The application devises a kind of novel underwater static fracturing agent and preparation method thereof, is become by difference
The proportioning combination divided realizes static breaking agent and crushes rock and concrete under water.
Summary of the invention:
It is an object of the invention to the shortcoming overcoming prior art to exist, seeking design provides one
Underwater static fracturing agent and preparation method thereof, solving current static breaking agent can not in water directly
The technical barrier of static crushing concrete works.
To achieve these goals, the underwater static fracturing agent that the present invention relates to contains following weight
The component of proportioning: burning calcium oxide 80-95%, portland cement 2.7-14.7%, calcium chloride
0.5-2%, UWB-II type non-dispersible underwater concrete flocculant (is the most all called for short UWB-II to wad a quilt with cotton
Solidifying agent) 2-3%, polycarboxylate water-reducer 0.3%；Described burning calcium oxide refers to limestone calcination
The fine and close quick lime formed after excessively.
The preparation method of the underwater static fracturing agent that the present invention relates to is: with fineness for 35-30 μ
Burning calcium oxide be main component, with portland cement for condense sclerosing agent, with calcium chloride be
Early strength agent, with UWB-II type non-dispersible underwater concrete flocculant as flocculant, with polycarboxylic acids
Water reducer is water reducer, is 80-95%:2.7-14.7% by mentioned component according to percentage by weight:
0.5-2%:2-3%:0.3% dry mixing is i.e. configured to underwater static fracturing agent after being uniformly dispersed, and is used for
The hole drilling type of body firm to coagulation great soil group is broken or swollen strong.
The first using method of the underwater static fracturing agent that the present invention relates to is: account under water according to water
The 28%-32% of static breaking agent percentage by weight weighs water and underwater static fracturing agent, will weigh
Good underwater static fracturing agent is poured into water, and bevelling stirring in limit is until stirring into pasty state slurry, so
After pasty state slurry is poured in injection vessel, by diver with under water and by injection vessel
Pasty state slurry is injected in band water cannon hole so that the water in big gun hole is extruded, then with stone or brick
Block pushes down the big gun hole filled, the inspection later being carried out broken situation by diver in 24 hours.
The underwater static fracturing agent the second using method that the present invention relates to is: account under water according to water
Static breaking agent percentage by weight is that the ratio of 28-32% weighs water and underwater static fracturing agent,
Being poured into water by underwater static fracturing agent, bevelling stirring in limit is until stirring into pasty state slurry, then
Pasty state slurry poured in the plastic bag of straight tube structure and be wound around sealing with rope, then by diver
Straight tube plastic bag after sealing is loaded in big gun hole, by diver to broken feelings after 24 hours
Condition checks；The diameter of the plastic bag of described straight tube structure and the diameter less than or equal to big gun hole,
Length is more than the degree of depth in big gun hole.
Using burning calcium oxide as main component in the present invention, there is hydration reaction after adding water in it
Cause volumetric expansion, thus be applied to hole wall slowly, quietly by the bulbs of pressure and then will mix
Solidifying soil is broken；The condensation sclerosing agent portland cement added adds solidification intensity；Add
Flocculation agent UWB-II flocculant be the macromolecular compound of a kind of polysaccharide, on the one hand,
Particle surface current potential in mixture dispersion can be changed after UWB-II flocculant and water mix,
Significantly increase the potential energy attracted between granule, make mixture thickness not disperse；On the other hand, UWB-
Containing long chain macromolecule compound in II flocculant, long chain macromolecule compound and calcium oxide particle
Absorption, forms stable netted knot by contact of building bridge crisscross between calcium oxide particle
Structure, and macroscopically showing as cohesion so that mixture becomes thickness and irrigates in water
Time do not isolate, do not disperse；The water reducer polycarboxylate water-reducer added, it is possible to ensure under water
The ratio of mud suitable when static breaking agent and water generation chemical reaction and pour mobility；The most former
Reason is: the UWB-II flocculant composition contained in the application so that underwater static fracturing agent with
The mixture of water has cohesiveness, and during underwater grouting, its surface touches water and can increase in addition
The ratio of mud causes the bulbs of pressure of cracking agent to reduce and affect crushing effect, therefore adds polycarboxylic acids
Water reducer, this water reducer is a kind of anion surfactant, it is possible to by its oriented adsorption power
Make cracking agent surface with the electric charge of same-sign, thus make brokenly under the effect that the same sex is repelled each other
Broken dose of aqueous systems is in metastable suspended state, can make the water release in structure simultaneously
Out to reach diminishing purpose；If only using mentioned component one or more as static breaking agent
Add water mix time, then can occur in water dispersion run off and concrete under water can not be directly injected into
In big gun hole.
The present invention compared with prior art, novelty of selecting materials, preparation technology is simple, proportioning science,
Finished product expansive force is big, force of explosion is strong, demolition effect is good, and cracking time is short and safety coefficient is high,
Nuisanceless, pollution-free；Safety is good, and construction period is little, and construction cost is low, environmental friendliness.
