Description
【Technical field】
The invention belongs to Tunnel Blasting technical field of construction, especially a kind of to stablize for improving periphery weak surrounding rock explosion
The loading method of property.
【Background technique】
Weak surrounding rock itself is relatively developed compared with broken, joint, layer adhesion power is small, degree of consolidation is poor, and when blast working easily makes
It loosens and falls off at the affecting of arch country rock, scalability, security risk is high, is easy to appear the safety accidents such as landslide, influences to construct
Safety and progress.
For the blast working of weak surrounding rock, improving charging means is one of the method for improving its explosion stability, is also had
Its explosion stability is improved by interval Uncoincided charge mode, but the effect is unsatisfactory, the research of other this respects is also not
See relevant report.
【Summary of the invention】
To solve the above problems, the present invention provides a kind of for improving the powder charge side of periphery weak surrounding rock explosion stability
Method can effectively improve the explosion stability of periphery weak surrounding rock by the improvement of the loading method, mention for Tunnel Blasting construction
For advantage, construction cost is saved.
For achieving the above object, the present invention adopts the following technical scheme that：
It is a kind of for improving the loading method of periphery weak surrounding rock explosion stability, the loading method use explosive cartridge,
Waterglass, alum and stemming, it is characterized in that：
Waterglass, alum are first fabricated to waterglass packet, alum packet respectively, the modulus of waterglass is equal to 3, waterglass packet and
The quality proportioning of alum packet is：Waterglass packet:Alum packet=100:1, according to quality≤water of its explosive cartridge of quality proportioning
The quality of glass bag can be packed into several explosive cartridges by construction requirement in each borehole；
It is initially charged with explosive cartridge in each borehole, is reloaded into waterglass packet, be finally packed into alum packet and constitutes first dress
Medicine circulation may be constructed second powder charge circulation by first powder charge circulation, and so on can be formed by several powder charges
Borehole is implemented to block by circulation, all powder charge circulations by stemming after the completion；
It is influenced when explosion by Explosive Shock Wave, waterglass and alum generate mixture, and the part mixture is impacted
Onto weak surrounding rock peripheral surface, the mixture is filled in the crack of periphery weak surrounding rock and generates within a short period of time solidifying
Gu having some strength after the mixture solidification, that is to say, that one layer of reinforcement material is coated on the weak surrounding rock of periphery, from
And improve the explosion stability of periphery weak surrounding rock.
Due to using technical solution as described above, the present invention generates following good effect：
1. waterglass and alum that the present invention uses are common materials, this is provided just for the blast working of weak surrounding rock
Sharp condition.
2. the present invention is in powder charge process, it is only necessary to be put into waterglass packet and alum packet at regular intervals in each borehole
, do not need to increase additional workload.
3. the mixture that waterglass and alum mixing generate after explosion is impacted on the weak surrounding rock of periphery, it is filled with periphery
The crack of weak surrounding rock, and have some strength after solidifying, it is also equivalent to that periphery weak surrounding rock is made to implement reinforcing process.
4. loading method of the invention can be such that periphery weak surrounding rock is reinforced at the first time after the completion of explosion, reinforce
Time is timely and effective, can effectively improve the explosion stability of periphery weak surrounding rock.
5. loading method simple possible of the invention, practicability is stronger, works well.
【Detailed description of the invention】
Fig. 1 is the structure schematic diagram of loading method.
In Fig. 1：1- explosive cartridge；2- waterglass packet；3- alum packet；4- stemming.
【Specific embodiment】
The present invention is a kind of for improving the loading method of periphery weak surrounding rock explosion stability, passes through the loading method energy
It is improved the stability of its peripheral rock after weak surrounding rock explosion, reduces wall rock loosening chip off-falling phenomenon after explosion, is improved soft
Weak country rock blast working safety.
Loading method of the invention uses explosive cartridge, waterglass, alum and stemming, and wherein waterglass and alum are normal
See material, this provides convenience condition for the blast working of weak surrounding rock.
In conjunction with Fig. 1, waterglass, alum are first fabricated to waterglass packet 2, alum packet 3 respectively, the modulus of waterglass is equal to 3,
The quality proportioning of waterglass packet and alum packet is：Waterglass packet:Alum packet=100:1, according to its explosive cartridge of the quality proportioning
1 quality≤waterglass packet quality, can be packed into several explosive cartridges 1 by construction requirement in each borehole.
It is initially charged with explosive cartridge 1 in each borehole, is reloaded into waterglass packet 2, be finally packed into alum packet 3 and constitutes first
Powder charge circulation may be constructed second powder charge circulation by first powder charge circulation, and so on can be formed by several dresses
Borehole is implemented to block by medicine circulation, all powder charge circulations by stemming after the completion.
It is influenced when explosion by Explosive Shock Wave, waterglass and alum generate mixture, and the part mixture is impacted
Onto weak surrounding rock peripheral surface, the mixture is filled in the crack of periphery weak surrounding rock and generates within a short period of time solidifying
Gu having some strength after the mixture solidification, that is to say, that one layer of reinforcement material is coated on the weak surrounding rock of periphery, from
And improve the explosion stability of periphery weak surrounding rock.
The present invention does not limit to the water glass solution and alum used, it is all with it is other similar in water glass solution and alum material
Similar material belongs to the scope of the present invention.
By above statement, loading method simple possible of the invention, practicability is stronger, works well, can be complete in explosion
Tentatively periphery weak surrounding rock is centainly reinforced at rear first time, the benefit of generation is also obvious.
