Description
Technical field
The invention patent relates to a kind of methods for controlling rock or concrete disintegrating pattern.
Background technology
Static breaking agent is a kind of new material being crushed brittleness medium using material expand performance, is widely used in being crushed
Concrete and rock fragile materials, static crushing with no shock wave, it is shockproof, without slungshot, it is noiseless, without pernicious gas and
The advantages that nuisanceless.Broken purpose is different, and the breaking patterns of the required body that is broken are also different, in temporary concrete structure
Need will to be broken in dismounting body in plum blossom-shaped or it is netted be broken into multiple fritters, in roof release and improve coal seam and permeate
Property engineer application in, the propagation direction of crackle need to be controlled, to improve crushing efficiency, ensure construction safety.Due to concrete and
Rock is anisotropism material, in shattering process, other than the lead crack occurred on drilling line, is also easy to occur other
The crackle in direction, breaking patterns are not easy to control, and when site operation, the breaking patterns of rock or concrete, general to do in order to control
Method is to carry out intensive drilling, but can greatly increase workload and construction cost.Factors above is considered, for economically and efficiently
Control the breaking patterns of rock or concrete, patent of the present invention provides a kind of for controlling rock or concrete disintegrating pattern
Method.
Invention content
Patent of the present invention provides a kind of method for controlling rock or concrete disintegrating pattern, by using inhomogeneity
The guider of type is equipped with suitable pattern, can achieve the purpose that control rock or concrete disintegrating pattern.By
Bore inner placement guide device achievees the purpose that control direction of crack propagation.Size incision by changing cylinder adjusts static
The size for the tensile stress that cracking agent is generated in cylinder incision site, have the function that adjusting hole away from, to reduce workload and
Construction cost.Achieve the purpose that effective controlled loading of explosive amount by the graduation mark of guide sidewall.It is equipped with using this guider
Suitable pattern can control the breaking patterns of rock or concrete.
Realize that the technical solution of above-mentioned purpose is as follows：
Guider is made of three-dimensional guider and four-way guider.Guider by the quantity containing different incisions steel
Rounding cylinder and handle composition.Three-dimensional guider by containing three notch steel cylinder and handle form, four-way guider by
Steel cylinder and handle composition containing four notch.
Two kinds of guiders are for controlling different breaking patterns.Three-dimensional guider is cut for crackle when being crushed to three
Mouth Directional Extension, four-way guider is extended for crackle when being crushed to four cut-out directions, using three-dimensional guider, four-way
Guider and quincunx pattern, the body that can make to be broken are broken in plum blossom-shaped.Using four-way guider and criss-cross
Pattern, the body that can make to be broken is in latticed broken.By taking three-dimensional guider as an example, used among the cylinder containing three notch
The plane included angle of arbitrary two notch is 120 ° in the static breaking agent slurry that filling is stirred, three notch, utilizes fragile material
Tensile strength far below compression strength and cylinder incision site easily occur tensile stress concentration principle, make the body that is broken
It is easy to crack in cylinder incision site, achieve the purpose that control direction of crack propagation.According to when one timing of body size that is broken, drilling
The turgor pressure of interior generation is bigger, and required pitch-row smaller principle when being crushed is changed out by controlling the size of cylinder notch
The size for the stretching concentrated force that mouth position generates, to change broken required pitch-row.Handle for after the completion of broken by guider
Drilling is extracted, can be reused.Graduation mark on cylinder side wall is used to that when powder charge explosive payload can be efficiently controlled, and reaches
To the purpose for saving construction cost.Patent of the present invention is suitable for control the breaking patterns of rock or concrete, with it is easy to make,
The features such as simple in structure, reusable.

Specific implementation mode
Patent of the present invention is described in further detail below with reference to the drawings and specific embodiments：
It needs clearly to be crushed purpose before construction, if body of wishing to be broken is broken in plum blossom-shaped, pattern should be quincunx, choosing
The guider taken is three-dimensional guider and four-way guider, is bored by the breakage parameter of design being broken on body
Guider is placed on bore inner by hole, and three-dimensional guider is placed on the drilling of highest and lowest two rows, four-way when placement
Guider is placed on the drilling in centre position, as shown in figure 5, the cut-out direction of cylinder and expected direction of crack propagation phase
Together, then design mixture proportion pours into drilling after stirring evenly static breaking agent and water, is seen by the graduation mark on cylinder side wall
Slurry perfusion situation is examined, stops powder charge when static breaking agent slurry is more than rock or top of concrete, after the completion of perfusion, in quilt
Broken body top is laid with one layer of covering, prevents spray orifice.The body that is broken will be crushed in plum blossom-shaped.If body of wishing to be broken is in grid
Shape is broken, and pattern should be criss-cross, and the guider of selection is four-way guider, and the breakage parameter by design is being broken
It drills on broken body, guider is placed on bore inner, the cut-out direction of cylinder and expected crack propagation when placement
Direction is identical, as shown in fig. 6, then design mixture proportion pours into drilling after stirring evenly static breaking agent and water, passes through cylinder
Situation is perfused in graduation mark observation slurry on side wall, stops dress when static breaking agent slurry is more than rock or top of concrete
Medicine, as shown in fig. 7, after the completion of perfusion, being broken, body top is laid with one layer of covering, prevents spray orifice.The body that is broken will be in side
Trellis is broken.
