Description
Technical field
The utility model relates to a kind of demolition set, relates in particular to a kind of bullet shape demolition set of administering bittern burst of brine well.
Technical background
The water-soluble bittern burst of brine well that often runs in the salt production of adopting endangers very big; Not only can make and produce salt well and stop production and scrap and strengthen cost of winning; Also can't set the exploitation of nugget and cause the huge wasting of resources; Even more serious is that bittern burst of brine well can cause generations such as groundwater pollution, house collapse, grainfield salinization of soil.Bittern burst of brine well has become the seed of trouble that jeopardizes ordinary production and sustainable development, brings disaster to the potential risk of the production zone ecological homeostasis and social stability especially.Administering scurrying the halogen well, is to eliminate the basis that the production zone geological environment destroys and even geological disaster takes place; It is the guarantee of safeguarding ordinary production and sustainable development; Sharp especially in the present age, that benefits future generations is necessary.
At present; The most advanced most effectual way of administering bittern burst of brine well is to adopt blasting technique; Comprehensive utilization dynamics of explosion, wave theory, controlled blasting and the principle of damming realize explosion; Utilize the explosive charge energy thoroughly to destroy plug section well cementation layer and local basement rock, form the director circle column cavity of the outer basement rock of recessed well, and make the chamber edge produce the effect in crack.Satisfied making shutoff imbed basement rock and thoroughly block salt well all scurry the halogen passage, and made shutoff, well cementation layer and basement rock three closely be condensed into needs such as integral body, had the effect of eliminating bittern burst of brine well thoroughly, lastingly.
The blasting technique key of administering bittern burst of brine well is to make demolition set; After the coupling explosive is confirmed; It is prepared into suitable shapes; Reach the external world that both helps getting rid of in the powder charge process and immerse and pollute, be beneficial to the mechanical property, explosion property and the explosion energy utilization rate that improve the quick-fried medicine of coupling again, and satisfy requirement such as powder charge.Under sending powder charge to mating under the exposed medicine of explosive employing, packing, send powder charge, play under the shape and send Charge Test to show; Exposed medicine demolition set, pack medicine demolition set exist all that powder charge is unreliable, explosive is vulnerable to corrosion contamination, send also shortcoming such as inconvenience down, and these two kinds of demolition sets all can not be controlled the direction and the energy of blast.From the driving outer protectiveness, particularly obtain aspects such as the reliability consideration of reasonable charge constitution and control effect of the reliability of sending charging operation down and simplicity, explosive, will mate explosive and be prepared into shell shape demolition set and obviously be superior to other form of structure.
Summary of the invention
The purpose of the utility model is in order to overcome the shortcoming of prior art, provides that a kind of powder charge is reliable, protectiveness good, can regulate and control the bullet shape demolition set of the improvement bittern burst of brine well of explosion energy.
The utility model is realized through following scheme: a kind of bullet shape demolition set of administering bittern burst of brine well; It comprises attaching nut, detonator lead-in wire, unload solenoid, on lead awl, shell, explosive, detonator bundle, central tube, blast packer, said shell is the cylindrical tube of a band shape V-shaped groove, an end of shell and conical blast packer join; The other end and last guiding awl join; Last guiding awl with unload solenoid and link to each other, unload solenoid one end and be provided with the attaching nut, unload solenoid, go up that guiding is bored and the center of shell is provided with a central tube; Be provided with detonator bundle and detonator lead-in wire in the central tube, be filled with explosive between central tube and the shell.
Further, shell and central tube are processed by metal material.
The technique effect of the utility model is following:
This utility model is owing to adopt such scheme and device, satisfied the demand of under the complex working condition condition, destroying plug section well cementation layer and local basement rock and forming cavity etc.Especially has the bullet shape device that produces with regulation and control blast ability to combined preparation one-tenth such as coupling explosives; Both made explosive directly not contact the bittern and the borehole wall in the well; Got rid of that environment pollutes the burn into of explosive and destruction such as friction, improved the mechanical properties and blast ability such as anti-pressure ability of explosive again effectively.
Description of drawings
Fig. 1 is the structural representation of the utility model.
In the accompanying drawing: 1, attaching nut; 2, detonator lead-in wire; 3, unload solenoid; 4, go up the guiding awl; 5, shell; 6, explosive; 7, detonator bundle; 8, central tube; 9, blast packer.
The specific embodiment
Shown in accompanying drawing 1, a kind of bullet shape demolition set of administering bittern burst of brine well, by attaching nut l, detonator lead-in wire 2, unload solenoid 3, go up guiding awl 4, shell 5, explosive 6, detonator bundle 7, central tube 8, blast packer 9 form.
Said shell 5 is the cylindrical tube of a band shape V-shaped groove; One end of shell 5 and conical blast packer 9 join, and the other end and last guiding awl 4 joins, last guiding bore 4 with unload solenoid 3 and link to each other; Unload solenoid 3 one ends and be provided with attaching nut 1; The center of unload solenoid 3, going up guiding awl 4 and shell 5 is provided with a central tube 8, is provided with detonator bundle 7 and detonator lead-in wire 2 in the central tube 8, is filled with explosive 6 between central tube 8 and the shell 5.Said explosive 6 is the mixing molten-castings of RDX and TNT, and its set of dispense is than being (weight ratio): RDX50～30%, TNT50～70%.Shell 5 and central tube 8 are processed by metal material.
With the method for boring or logging well down; The bullet shape demolition set of the utility model delivered to along salt well be fit to make stifled place in the above rock section of salt well topmost salt deposit top board; Apparatus to cause bursting; After the ignition, the effect of the modulated device of huge energy that explosive charge discharges smashes sleeve pipe, cement sheath and the local basement rock of plug section; Forming one is that center, axial length are a bit larger tham device length, radially protrudingly advance basement rock and can reach several meters director circle column cavity with the borehole axis line, and the cavity outer rim is the brand-new bedrock surface with the crack; In addition, the blast packer 9 of device is fastened in after blast dilates in the salt well of plug section below, again through the impact compacting and the covering of quick-fried quarrel, below the plug section, forms a stifled in advance partition bottom and has adopted molten chamber; The cavity upper center is communicated with salt well, and the lower end is stifled in advance the partition, realizes the target that the explosion preparation cuts halogen shutoff cavity.Use drape process at the bottom of the hole then, cement paste is pressed in cavity annotate, form and both imbedded the outer basement rock of well, make basement rock, well cementation layer and shutoff three closely condense into whole embedding rock again and cut and scurries shutoff until diffusing out from well head.Reached and thoroughly blocked the original halogen passage of scurrying of salt well, eliminated the improvement purpose of bittern burst of brine well reliably, lastingly.
Those of ordinary skill in the art will be appreciated that; Above embodiment only is the purpose that is used for explaining the utility model; And be not with the qualification of doing the utility model; As long as in the essential scope of the utility model, in the scope to the variation of the above embodiment, claim that modification all will drop on the utility model.
