Abstract
A kind of waterproof method for plastic detonating cord end, the polishing of (1) plastic detonating cord end surface；(2) epoxy resin is coated in plastic detonating cord end；(3) glass cement is coated in cable connection cap, plastic detonating cord end is inserted into cap inwards, place twenty four hours naturally；(4) plastic detonating cord is exposed at the part that the residual surface outside cable connection cap has been polished by close end and uniformly smears sealant, puts on double-walled heat-shrinkable T bush；(5) double-walled heat-shrinkable T bush is put on candle flame and bakes, its contraction is made to hold tightly together with plastic detonating cord；(6) plastic detonating cord end is wound with insulating tape；(7) adhesive waterproof tape is used to wind again in the outer layer of insulating tape.The present invention is with strong points, using the technology in the case where, the depth of water larger to water pressure relatively depth, when carrying out bursting work, plastic detonating cord is soaked in water within seven days under effect of water pressure, still is able to proper detonation explosive, construction is simple convenience, good water-proof effect, it is low-cost, fully ensure that plastic detonating cord can safe initiation explosive, to guarantee the safe and effective of bursting work.
Description
Technical field
The present invention relates to a kind of waterproof methods more particularly to one of the plastic detonating cord end used when underwater demolition
It is to guarantee that under effect of water pressure, it is fried still to be able to proper detonation for plastic detonating cord when kind for carrying out bursting work under water
Medicine needs to carry out plastic detonating cord end the waterproof method of the plastic detonating cord end of water-proofing treatment.
Background technique
When carrying out explosion under water, it is often necessary to use plastic detonating cord detonating charge, conventional plastic detonating cord is in factory
After the completion of family's production, transport to live use, water pressure is larger, the depth of water relatively depth in the case where, the end of common plastic detonating cord
Portion is after water impregnates, it is easy to lose original effect, it cannot be guaranteed that its performance is constant, influence plastic detonating cord detonating charge
Detonation Initiation Effect, to influence the safety blasting of explosive, may cause explosive cannot explode under water by scheduled requirement, generate peace
Full hidden danger.For this purpose, for guarantee water pressure is larger, the depth of water relatively depth in the case where carry out underwater demolition when, plastic detonating cord
It being capable of safe initiation explosive, it is necessary to which water-proofing treatment is carried out to plastic detonating cord end.
Summary of the invention
In view of the above deficiencies or problem, the present invention provides a kind of waterproof methods for plastic detonating cord end, preferably
Ground solve water pressure is larger, the depth of water relatively depth in the case where carry out underwater demolition when, the waterproof of plastic detonating cord end
Problem.
The taken technical measures that solve the above problems are:
A kind of waterproof method for plastic detonating cord end, it is characterised in that:
(1) plastic detonating cord is polished by the plastic detonating cord surface of close end 2-3cm length range；
(2) one layer of propane type epoxy resin of di phenolic group is coated into plastic detonating cord end；
(3) it after coating polyurethane glass glue in cable connection cap, inwards by plastic detonating cord end, is inserted into cable and connects
In line cap, makes plastic detonating cord end top to cable connection cap innermost end, place twenty four hours naturally；
(4) plastic detonating cord the part that the residual surface outside cable connection cap has been polished is exposed at by close end uniformly to apply
A strata urethane glass cement is smeared, double-walled heat-shrinkable T bush is then put on；
(5) the double-walled heat-shrinkable T bush for covering on plastic detonating cord is put on candle flame and is baked, meet double-walled heat-shrinkable T bush
It is heat-shrinked, holds tightly together with plastic detonating cord；
(6) plastic detonating cord end is no less than within the scope of 100mm and is wound using insulating tape, each layer of insulation gluing
When band winding, latter circle has half-amplitude duration to be overlapped on previous circle above, winds 4 ~ 6 layers of insulating tape altogether；
(7) adhesive waterproof tape is used to wind again in the outer layer of insulating tape, when each layer of adhesive waterproof tape is wound, latter circle has
Half-amplitude duration is overlapped on previous circle above, winds 4 ~ 6 layers of adhesive waterproof tape altogether.
Beneficial effects of the present invention: when the present invention preferably solves progress bursting work under water, plastic detonating cord
Waterproof problem, this method is with strong points, using the technology in the case where, the depth of water larger to water pressure relatively depth, carries out bursting work
When, plastic detonating cord is soaked in water within seven days under effect of water pressure, still is able to proper detonation explosive, construction is simple
Convenient, good water-proof effect, it is low-cost, fully ensure that plastic detonating cord can safe initiation explosive, to guarantee bursting work
It is safe and effective.
Specific embodiment
Below with reference to embodiment, the present invention will be described in detail.
A kind of waterproof method for plastic detonating cord end, the steps include:
(1) length that finished plastic primacord is needed to be cut into requirement according to practical explosion first, then by well cutting
The both ends of every plastic detonating cord polish by the plastic detonating cord surface of close end 2-3cm length range；
(2) after the completion of polishing, one layer of propane type epoxy resin of di phenolic group is coated into the end at every plastic detonating cord both ends；
(3) every plastic detonating cord is needed with two finished cable wiring caps, on each cable connection cap inner wall uniformly
After a strata urethane glass cement is coated on ground, every radicle is coated with the plastic detonating cord both ends of propane type epoxy resin of di phenolic group
End is respectively facing cable connection cap inner end, is inserted respectively into the cable connection cap for being coated with polyurethane glass glue on inner wall,
It pushes up the both ends end of every plastic detonating cord to cable connection cap innermost end, places twenty four hours naturally；
(4) plastic detonating cord is exposed at the part that the residual surface outside cable connection cap has been polished by the end of two close end
A strata urethane glass cement is uniformly smeared, double-walled heat-shrinkable T bush is then put on；
(5) the double-walled heat-shrinkable T bush for covering on plastic detonating cord is put on candle flame and is baked, meet double-walled heat-shrinkable T bush
It is heat-shrinked, holds tightly together with plastic detonating cord；
(6) every end at plastic detonating cord both ends is no less than within the scope of 100mm by close end and is wound using insulating tape,
When each layer of insulating tape winding, latter circle has half-amplitude duration to be overlapped on previous circle above, winds 4 ~ 6 layers of insulation gluing altogether
Band；
(7) adhesive waterproof tape is used to wind again in the outer layer of insulating tape, each latter circle of layer has half-amplitude duration to be overlapped on
Previous circle above, winds 4 ~ 6 layers of adhesive waterproof tape altogether.
Plastic detonating cord after processing is completed, can be used to underwater demolition, and with plastic detonating cord detonating charge, plastics are led
Quick-fried rope is soaked in water within seven days under effect of water pressure, still is able to proper detonation explosive, to guarantee bursting work
Safely and effectively.
