Description
Technical field
A kind of binding energy tube is the utility model is related to, especially a kind of directional splitting binding energy tube.
Background technology
At present, when tunnel or tunnel are constructed using drilling and blasting method, generally using smooth Surface Blasting Technology, wherein periphery hole
Layout design serves vital to laneway molding；To reach smooth demolition effect, periphery hole arrangement spacing is small, number is more, leads
Cause the perforating activity duration longer, after explosion, not only form through check between blasthole, and excess energy of exploding to blasthole around
Rock mass also produces destruction, causes tunnel free face irregular, backbreaks or owe to dig larger, increase support work amount, so as to totle drilling cost
Increase；Therefore, it is badly in need of a kind of device to caused shock wave after explosive charge and detonation gas directional guide, makes rock mass orientation disconnected
Split, so that the problem of above-mentioned tunnelling process is present is reduced or avoided.
The content of the invention
In order to overcome the free face of tunnel blasting at this stage irregular, backbreak or owe dig it is larger, increase support work amount with
The problem of totle drilling cost, the utility model provide a kind of directional splitting binding energy tube, a kind of directional splitting binding energy tube, orient quick side
Just, simple in construction, it makes powder stick form two symmetrical troughs for collecting energy, high detonation pressure caused by explosion time in use
Become big by taper reinforcing bar and be applied to rock mass, produce the powerful tensile stress vertical with tunnel contour line direction, reach orientation
Effect is cleaved, this is a kind of new technical scheme, easy to utilize.
The technical solution adopted for the present invention to solve the technical problems is：A kind of directional splitting binding energy tube, including：One kind is fixed
There is the pvc pipe body of a long tubular to splitting binding energy tube, pipe diameter coincide with borehole diameter, tube length and borehole depth phase
Deng, therefore a borehole need to only be put into a body；Joint-cutting is symmetrically provided with the tube wall of body；Joint-cutting in the axial direction away from
Certain safe distance is respectively stayed in body rear and front end, and body is not broken before ensureing explosion, symmetrical embedded two high rigidity cone in joint-cutting
Shape reinforcing bar；Two 5mm to be alignd with reinforcing bar breach is provided with the mouth of pipe of body front end；Straight uniform on the outside of the tube wall of body
Be provided with pipe thorn；After body is put into borehole along pipe thorn direction, it can not just be taken out again, therefore when multiple boreholes are quick-fried
In the case of broken existence time error, the binding energy tube of Loose Blasting intraocular is lagged under violent vibration, position will not also be sent out
It is raw to change, therefore ensure that binding energy tube joint-cutting direction is unified, improve the effect of explosion；In use, powder stick is filled into body, lack
The line direction alignment tunnel contour line direction of mouth, high detonation pressure caused by explosion time become big by taper reinforcing bar and are applied to
Rock mass, the powerful tensile stress vertical with tunnel contour line direction is produced, reaches directional splitting effect, this is a kind of new technology
Scheme, it is easy to utilize；The opening of the body is provided with stopper.
Beneficial effect of the present invention：A kind of directional splitting binding energy tube, orientation is quick and convenient, and simple in construction, it is using process
In, powder stick is formed two symmetrical troughs for collecting energy, high detonation pressure caused by explosion time becomes big by taper reinforcing bar and is applied to
Rock mass, the powerful tensile stress vertical with tunnel contour line direction is produced, reaches directional splitting effect, this is a kind of new technology
Scheme, it is easy to utilize.

Accompanying drawing 4 is sectional view after utility model body powder charge.
In figure：1. body, 1-1. stoppers, 2. taper reinforcing bars, 3. breach, 4. boreholes, 5. pipes thorn, 6. powder sticks.
Embodiment
In figure, a kind of directional splitting binding energy tube, body 1, stopper 1-1, taper reinforcing bar 2, breach 3, pipe thorn 5；One kind is fixed
There is the pvc pipe body 1 of a long tubular to splitting binding energy tube, the diameter of body 1 coincide with borehole diameter, and the length of body 1 is deep with borehole
Spend equal, therefore a borehole need to only be put into a body 1；Joint-cutting is symmetrically provided with the tube wall of body 1；Joint-cutting is in axial direction
Certain safe distance is respectively stayed in direction away from body rear and front end, and body is not broken before ensureing explosion, symmetrical embedded two height in joint-cutting
Hardness taper reinforcing bar 2；Two 5mm to be alignd with reinforcing bar breach 3 is provided with the mouth of pipe of the front end of body 1；Outside the tube wall of body 1
Side straight uniform is provided with pipe thorn 5；After body 1 pierces 5 directions along pipe to be put into borehole, it can not just be taken out again, because
In the case that this works as multiple hole firing existence time errors, the binding energy tube of Loose Blasting intraocular is lagged even in violent vibration
Under, position will not also change, therefore ensure that binding energy tube joint-cutting direction is unified, improve the effect of explosion；In use, will
Powder stick 6 fills body 1, the line direction alignment tunnel contour line direction of breach 3, and high detonation pressure caused by explosion time passes through cone
Shape reinforcing bar 2 becomes big and is applied to rock mass, produces the powerful tensile stress vertical with tunnel contour line direction, reaches directional splitting effect
Fruit, this is a kind of new technical scheme, easy to utilize；The opening of the body 1 is provided with stopper 1-1.
