Along with economic fast development, the use of a large amount of chemical substances has resulted in soil and groundwater dirt in various degree
Dye.And due to the leaching of rainwater and the fluctuation of level of ground water, the cross-contamination of soil and groundwater also can be caused.In general,
In soil and groundwater, typical pollutant have: inorganic matter and Organic Pollution, including NO3 -、NH4 +, heavy metal Pb, Cr, As
Deng, benzene homologues, petroleum hydrocarbon, Polychlorinated biphenyls, pesticide etc..These pollutant often have high toxicity high carcinogenic, it is therefore necessary to logical
Cross rational technological means and repair these contaminated soil and groundwaters.
Soil and groudwater remediation technology mainly has showering and in-situ immobilization at present.Showering will contaminated soil
Dig out, transport, repair.This repair mode not only workload is big, also can cause the secondary pollution of air, it is also possible to because of microorganism
Nearby residents is impacted by the stench product acted on and produce.Compared with showering technology, in-situ immobilization has protection dirt
The advantages such as dye treatment of the earth, recovery project amount is little, rehabilitation cost is low.In-situ immobilization includes biology in situ reparation, phytoremediation, change
Learn reparation etc..These technology generally require in suitable biological preparation or chemical agent in-situ injection to soil and groundwater,
Biology or medicament are sufficiently mixed, to reach the purpose repaired with the soil body and subsoil water.
Traditional injection technique is that the mode using injection rod to press down is carried out, not only inefficiency, and is difficult to penetrate sand
The hardpans such as gravel layer, vibrations are strongly.There is the method utilizing hydraulic system to carry out in-situ injection of improvement afterwards, improve and set
Standby stability and work efficiency.
But medicament required in based technique for in-situ remediation is often the common effect of two or more medicament, such as original positionization
Learn Fenton reagent conventional in oxidation, consisting of main body medicament H2O2And activator.Fenton reagent injects existing construction technology
It is by after medicament mixing, is injected in soil and groundwater by injector well.But the speed that main body medicament and activator react
Very fast, if reinjected after mixing in advance, before contacting with pollutant, oxidisability is had a greatly reduced quality, it is impossible to have well
The hydroxyl radical free radical OH of effect, its effect repairing pollutant also will be far below expection.
Accordingly, it would be desirable to a kind of injection device in situ of design, two or more medicament can be mixed in underground, to reduce medicine
Reacting to each other between agent so that medicament maintains the optimal property of medicine with polluting when body contacts, and reaches best repair effect.

Detailed description of the invention
The nonrestrictive concrete structure disclosing a kind of embodiment of this utility model of accompanying drawing, below in conjunction with the accompanying drawings to this reality
It is further described with novel.
Boring rod set of the present utility model is the carrier of medicament, is also boring, the executor of perforating, for soil and ground
In lower water recovery technique to pollute body hole, perforating and medicament injection.Can by the single or multiple lengthening connecting rods of employing
To adapt to the injection demand of polluter different depth.
As it is shown in figure 1, the drilling rod of the present embodiment is designed as double-layer hollow sleeve structure.In pushing up outer bar 5 and top, bar 4 passes through spiral shell
Stricture of vagina connects, and lengthens between outer bar 3 and drill bit assembly 1 threaded with NPT, uses common spiral shell in lengthening between bar 2 and drill bit assembly 1
Stricture of vagina connects.The bottom interior wall lengthening outer bar 3 is provided with step, by between outer bar and interior bar together with the outer wall of bar 2 in lengthening
Cavity bottom is closed, and is ensured its sealing by O-ring 11；Meanwhile, the inner chamber of bar 4, the inner chamber lengthening interior bar 2 and drill bit 9 in top
Internal cavity connection.So can form the cavity volume of two relative closures, be used for carrying two kinds of medicaments of A, B.
In the present embodiment, in lengthening outer bar 3 and lengthen, the end of bar 2 is set to tenon structure, its one end male, one end
Female, can be overlapped using according to drilling depth.
In top, one end of bar 4 can also be set to female or male head structure, with lengthen in bar 2 tenon structure with the use of；
Its other end is connected with hydraulic tube 6.Preferably, hydraulic tube 6 is flexible pipe, because tired between bar and outer bar in scalable in its length
Long-pending length difference.One end of hydraulic tube 6 is connected with bar 4 in top, and the other end passes through angle coupling 8 and pushes up outer bar 5 with being screwed, directly
Angle joint 8 is connected with medicament B.Pushing up and be separately welded with straight coupling 7 on outer bar 5, straight coupling 7 is connected with medicament A.
Have 2-5 jet that connect with medicament A injecting cavity, that tilt upward on drill bit 9, and inject with medicament B
2-5 jet that chamber connects, diagonally downward, these two groups of jets are positioned at Different Plane so that medicament ejector is to polluting body
After can quickly mix.A high pressure nozzle 13 is welded in each jet.Wherein, angle of inclination, jet number and two groups
Vertical interval between jet can select according to actual geology condition free and arrangement.
It is provided with back-moving spring 10 and non-return valve pocket 12 in the bottom of drill bit inner chamber, backflow of underground water can be prevented.Non-return valve pocket
O-ring 11 can be provided with between 12 and drill bit inner chamber and ensure its sealing.When in medicament B injecting cavity, medicament reaches to set pressure, meeting
Opening non-return valve pocket 12, medicament B can spray from jet, when pressure is less than when setting pressure, and back-moving spring 10 makes check-valves
Set 12 reset, can block jet and prevent backflow of underground water.
As in figure 2 it is shown, the boring rod set of the present embodiment is operationally, when drill bit 9 position arrives gdna contamination, can be simultaneously
Being injected separately into medicament A and medicament B, two kinds of medicaments are sprayed from its jet by respective conveyor chamber, and two kinds of medicaments mix at medicament
Mix at face, can effectively ensure that the reparation pollution time, solve medicament and first mix the problem reinjecting pollution body property of traditional Chinese loss.
Described in above example, only this utility model preferably detailed description of the invention, these detailed description of the invention are all
Based on the different implementations under this utility model general idea, and protection domain of the present utility model is not limited thereto,
Any those familiar with the art in the technical scope that this utility model discloses, the change that can readily occur in or replace
Change, all should contain within protection domain of the present utility model, realize the mixing of more kinds of medicament as arranged multilayer sleeve structure
