Description
Technical field：
The invention belongs to soundless cracking technical fields, and in particular to a kind of underwater static fracturing agent and preparation method thereof, it will
Static crushing technology is introduced in underwater operation, realizes the static crushing of Underwater Engineering.
Background technology：
Static crushing technology is the method for a kind of new fractured rock and concrete developed in recent years, and being will be static
Cracking agent occurs hydration reaction by cracking agent itself and generates volume expansion plus in injection blasthole after the cooperation of suitable water, from
And it slowly, quietly by the bulbs of pressure is applied to hole wall, medium is crushed；Used static breaking agent also known as soundless cracking
Agent, in Chinese name republic building material industry standard《Soundless cracking agent》It is " all warps defined in (standard No. JC506-2008)
Inorganic compound of the high-temperature calcination based on calcium oxide, mixing has high expansion function made of appropriate additive intergrinding
The broken pulverulent material of non-explosion ", can be reliable in the restricted place safety of explosive blasting since it does not generate public hazards
Implement explosion, and is widely applied in the various occasions such as cities and towns, workshop, machine, equipment.Static crushing in the prior art
It is main component that agent, which mostly uses calcium oxide, paraffin, Extend position etc., such as one disclosed in Chinese patent ZL201310368514.8
The static breaking agent that hidden hole drilling uses can be coordinated by planting, a kind of static breaking agent disclosed in Chinese patent ZL201410039857.4,
A kind of composition of static breaking agent, Chinese patent ZL200910090695.6 disclosed in Chinese patent ZL201110348685.5
A kind of static breaking agent etc. is disclosed, cannot achieve to be perfused in water and generate powerful expansive force without disperseing, and it is Chinese
A kind of static breaking agent and its manufacturing method disclosed in patent ZL99116548.9, although improving ingredient, in quick lime
In added FeCl ↓ [3] and cement, but be still difficult to achieve the desired results；And in putting into practice at present, underwater concrete is broken to be used
Method be still the traditional powers method such as explosion, hydraulic drill, pneumatic pick, cutting mostly, therefore in order to which static crushing technology is drawn
Enter in Underwater Engineering project, the application devises a kind of novel underwater static fracturing agent and preparation method thereof, by it is different at
The proportioning combination divided realizes that static breaking agent is under water crushed rock and concrete.
Invention content：
It is an object of the invention to overcome disadvantage of the existing technology, seeks design and a kind of underwater static fracturing agent is provided
And preparation method thereof, solve the technical barrier that current static breaking agent is unable to direct static crushing concrete works in water.
To achieve the goals above, underwater static fracturing agent of the present invention contains the component of following weight proportion：It crosses
Burn calcium oxide 80-95%, portland cement 2.7-14.7%, II type non-dispersible underwater concrete of calcium chloride 0.5-2%, UWB- wadding
Solidifying agent (II flocculants of abbreviation UWB- below) 2-3%, polycarboxylate water-reducer 0.3%；The burning calcium oxide refers to lime stone
The fine and close quick lime formed after calcining excessively.
The preparation method of underwater static fracturing agent of the present invention is：Based on burning calcium oxide with fineness for 35-30 μ
Ingredient is wanted, is condensation curing agent with portland cement, using calcium chloride as early strength agent, is wadded a quilt with cotton with II type non-dispersible underwater concretes of UWB-
Solidifying agent is flocculant, according to weight percent is 80-95% by mentioned component using polycarboxylate water-reducer as water-reducing agent：2.7-
14.7%：0.5-2%：2-3%：0.3% dry mixing is configured to underwater static fracturing agent after being uniformly dispersed, for coagulation great soil group
The hole drilling type of firm body is broken or swollen strong.
The first application method of underwater static fracturing agent of the present invention is：Underwater static fracturing agent weight is accounted for according to water
The 28%-32% of percentage weighs water and underwater static fracturing agent, and load weighted underwater static fracturing agent is poured into water, while falling
Then side stirring pours into paste slurry in injection vessel until stirring into paste slurry, brought to underwater and will note by diver
The paste slurry penetrated in container is injected into band water cannon hole so that the water in blasthole is extruded, then pushes down filling with stone or brick
Full blasthole is carried out the inspection of broken situation by diver after 24 hours.
Second of application method of underwater static fracturing agent of the present invention be：Underwater static fracturing agent weight is accounted for according to water
Percentage is that the ratio of 28-32% weighs water and underwater static fracturing agent, underwater static fracturing agent is poured into water, side bevelling stirs
It mixes until stirring into paste slurry, then paste slurry is poured into the polybag of straight tube structure and wound with rope and sealed, then
The straight tube polybag after sealing is fitted into blasthole by diver, broken situation is checked by diver after 24 hours；
For the diameter of the polybag of the straight tube structure with less than or equal to the diameter of blasthole, length is more than the depth of blasthole.
Using burning calcium oxide as main component in the present invention, generation hydration reaction causes volume expansion after adding water,
To which the bulbs of pressure slowly, are quietly applied to hole wall in turn by concrete disintegrating；Condensation curing agent --- the silicon of addition
Acid salt cement increases solidification intensity；II flocculants of the flocculant of addition --- UWB- are a kind of macromolecule chemical combination of polysaccharide
Object, on the one hand, can change particle surface current potential in mixture dispersion after II flocculants of UWB- and water mix, significantly increase
The potential energy attracted between particle makes mixture is sticky not disperse；On the other hand, long chain macromolecule chemical combination is contained in II flocculants of UWB-
Object, long chain macromolecule compound are adsorbed with calcium oxide particle, contact to be formed by crisscross bridge formation between calcium oxide particle
Stable reticular structure, and macroscopically showing as cohesion so that when mixture becomes sticky and is perfused in water not from
Analysis does not disperse；The water-reducing agent of addition --- polycarboxylate water-reducer can ensure that underwater static fracturing agent is chemically reacted with water
When the ratio of mud appropriate and pour mobility；Concrete principle is：The II flocculant ingredients of UWB- contained in the application so that underwater
The mixture of static breaking agent and water has cohesiveness, its surface touches water and can increase the ratio of mud during underwater grouting in addition
Cause the bulbs of pressure of cracking agent to reduce and influence crushing effect, therefore polycarboxylate water-reducer is added, which is a kind of the moon
Ionic surface active agent can make cracking agent surface carry the charge of the same symbol by its oriented attachment power, to same
Property makes cracking agent-aqueous systems be in metastable suspended state under the action of repelling each other, while the water in structure can be made to discharge
Out to reach diminishing purpose；It, can be if mentioned component one or more are only added water mix as static breaking agent
Dispersion occurs in water to be lost in and cannot be directly injected into underwater concrete blasthole.
Compared with prior art, the present invention sorting is novel, preparation process is simple, matches science, and finished product expansive force is big, explosion
Power 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 small, construction
It is at low cost, it is environmental-friendly.
