In the soil remediation industry, there are more than a hundred existing soil remediation technologies, and more than a dozen commonly used technologies, which can be roughly divided into three methods: physical, chemical, and biological. Since the 1980s, many countries in the world, especially developed countries, have formulated and carried out pollution soil treatment and remediation plans, thus forming a new soil remediation industry;

[0003] It is found that the publication number: CN212944641U discloses a liquid-phase medicament penetration injection device for contaminated soil remediation. In this technology, it is disclosed that "a cylindrical injection box, the upper end of the injection box is open, a sealing cover is detachably installed at the opening of the injection box, a liquid injection nozzle is installed on the sealing cover, a drill bit device is installed on the injection box, the drill bit device includes an excavation drill bit rotatably installed on the bottom surface of the injection box, a driving device is installed in the injection box, the driving device includes a rotating shaft cylinder, a through hole is opened on the bottom surface of the injection box, the lower end of the rotating shaft cylinder passes through and is fixed in the through hole, a driving shaft is arranged in the rotating shaft cylinder, the lower end of the driving shaft is fixedly connected with the drill bit device, and when the sealing cover covers the injection box, the sealing cover closes the upper end of the rotating shaft cylinder.

[0004] Although this design can drill holes on the ground with the excavation drill bit, easily bury the injection box into the holes, facilitating the installation by workers and improving the installation efficiency, this device can only perform simple injection work deep in the soil. However, when dealing with contaminated geological layers at different depths, it is difficult for this device to control the area to be repaired, which may cause additional consumption of the repair agent and result in waste of resources.

[0005] To solve the above problems, a liquid-phase medicament penetration injection device for contaminated soil remediation is proposed in this application. Content of the Utility Model

[0006] To solve the problems raised in the above background technique. The utility model provides a liquid-phase medicament penetration injection device for contaminated soil remediation. By adjusting the positions of the lower baffle and the upper baffle, the height change of the two in the repair pile can be realized. Furthermore, when injecting the repair agent into the repair pile through the medicine pipe, the medicament can be dispersed into the soil outside the repair pile in the area between the lower baffle and the upper baffle, thereby effectively reducing the consumption of the medicament and reducing the additional consumption of the medicament.

[0007] To achieve the above object, the present utility model provides the following technical solution: A liquid-phase agent penetration injection device for contaminated soil remediation, including a remediation pile, and further including an injection hole, a lower baffle, an injection pipe, a spraying hole, an adjusting screw, an upper baffle and a medicine pipe arranged on one side of the remediation pile. The injection hole is formed on the surface of the remediation pile, and the inner surface of the remediation pile is also slidably connected to the lower baffle. One side of the lower baffle is fixedly connected to one end of the injection pipe. At the same time, the spraying hole is formed on the surface of the injection pipe. The injection pipe is also threadedly connected to the inner surface of the adjusting screw. One end of the adjusting screw close to the lower baffle is fixedly installed with the upper baffle slidably connected to the inner surface of the remediation pile. And the adjusting screw is threadedly connected to the remediation pile. One end of the injection pipe away from the lower baffle is fixedly connected to the medicine pipe.

[0008] Preferably, as a liquid-phase agent penetration injection device for contaminated soil remediation of the present utility model, the shape of the remediation pile is a hollow cylindrical shape, and the end shape of the remediation pile is a conical geometric body.

[0009] Preferably, as a liquid-phase agent penetration injection device for contaminated soil remediation of the present utility model, the injection holes are uniformly formed on the surface of the remediation pile.

[0010] Preferably, as a liquid-phase agent penetration injection device for contaminated soil remediation of the present utility model, the shapes of the lower baffle and the upper baffle are disc-shaped with the same diameter.

[0011] Preferably, as a liquid-phase agent penetration injection device for contaminated soil remediation of the present utility model, the injection pipe is a hollow cylinder, and the spraying hole is communicated with the internal space of the injection pipe.

[0012] Preferably, as a liquid-phase agent penetration injection device for contaminated soil remediation of the present utility model, threads are provided on both the outer surface and the inner surface of the adjusting screw.

[0013] Compared with the prior art, the beneficial effect of the present utility model is that by adjusting the positions of the lower baffle and the upper baffle, the height change of the two in the remediation pile can be realized.

[0022] Embodiment 1

[0023] As Figure 1 shown:

[0024] A liquid-phase medicine penetration injection device for contaminated soil remediation includes a repair pile 1.

[0025] In this implementation: The existing publication number: CN212944641U discloses a liquid medicine penetration injection device for contaminated soil remediation. An injection box is disclosed in this patent. The repair pile 1 in this application document adopts the same technical means as in this prior art. This technical means will not be elaborated here one by one. For the improvement of this prior art, please refer to the disclosed technology below for details; to solve the technical problems existing in this prior art, such as the "the device can only carry out simple injection work deep into the soil, but when dealing with contaminated geological layers at different depths, it is difficult for the device to control the area to be repaired, which may lead to additional consumption of the repair agent and waste of resources" disclosed in the background art above. In combination, this problem is obviously a real and difficult problem to solve. In view of this, to solve the above problems, a medicine injection hole 2 and a lower layer baffle 3 are added on this basis.

[0026] Furthermore:

[0027] As Figure 1 - Figure 4 shown:

[0028] Combined with the above content: It also includes a medicine injection hole 2, a lower layer baffle 3, an injection pipe 4, a medicine spraying hole 5, an adjusting screw 6, an upper layer baffle 7 and a medicine pipe 8 arranged on one side of the repair pile 1. The surface of the repair pile 1 is provided with a medicine injection hole 2, and the inner surface of the repair pile 1 is also slidably connected to the lower layer baffle 3. One side of the lower layer baffle 3 is fixedly connected to one end of the injection pipe 4. At the same time, the surface of the injection pipe 4 is provided with a medicine spraying hole 5. The injection pipe 4 is also threadedly connected to the inner surface of the adjusting screw 6. One end of the adjusting screw 6 close to the lower layer baffle 3 is fixedly installed with an upper layer baffle 7 that is slidably connected to the inner surface of the repair pile 1. And the adjusting screw 6 is threadedly connected to the repair pile 1. One end of the injection pipe 4 away from the lower layer baffle 3 is fixedly connected to a medicine pipe 8.

[0029] In this embodiment: When soil at a certain position needs to be repaired, the repair pile 1 can be inserted into the soil. Subsequently, the heights of the lower baffle 3 and the upper baffle 7 can be adjusted according to the depth of the soil to be repaired. When adjusting the heights of the injection pipe 4 and the upper baffle 7, the injection pipe 4 can be rotated to cause rotation between it and the adjusting screw 6. At this time, the heights of the injection pipe 4 and the upper baffle 7 will change. The space of the repair pile 1 below the upper baffle 7 is blocked by the upper baffle 7. When rotating the adjusting screw 6, the injection pipe 4 can be controlled so that its axial direction remains unchanged, while the adjusting screw 6 will rotate with the repair pile 1 and drive the lower baffle 3 to slide along the inner surface of the repair pile 1 to achieve height change. At this time, through the changes of the lower baffle 3 and the upper baffle 7, flexible control of the soil repair position can be realized. Finally, the repair agent can be injected into the hollow injection pipe 4 through the medicine pipe 8 and flow into the repair pile 1 through the medicine spraying holes 5 opened on the surface of the injection pipe 4. Under the action of the lower baffle 3 and the upper baffle 7, the repair agent will be blocked between the lower baffle 3 and the upper baffle 7 and finally injected into the soil to be repaired through the medicine injection holes 2 opened on the surface of the repair pile 1.

[0030] Furthermore:

[0031] In an alternative embodiment, the repair pile 1 is in the shape of a hollow cylinder, and the end of the repair pile 1 is in the shape of a conical geometric body.

[0032] In this embodiment: The hollow repair pile 1 can provide effective space for the movement of the lower baffle 3 and the upper baffle 7. At the same time, the cylindrical tip enables the repair pile 1 to be conveniently inserted into the soil, which is conducive to the stable implementation of the repair work.

[0033] Furthermore:

[0034] In an alternative embodiment, the medicine injection holes 2 are evenly opened on the surface of the repair pile 1.

[0035] In this embodiment: The medicine injection holes 2 evenly opened on the surface of the repair pile 1 can enable the medicine between the lower baffle 3 and the upper baffle 7 to be injected into the soil outside the repair pile 1 through the medicine injection holes 2, so as to stably realize the soil repair work.

[0036] Furthermore:

[0037] In an alternative embodiment, the lower baffle 3 and the upper baffle 7 are in the shape of discs with the same diameter.

[0038] In this embodiment: The disc-shaped lower baffle 3 and upper baffle 7 can form a complete area inside the repair pile 1, and the area to be repaired can be adjusted according to the interval between the lower baffle 3 and the upper baffle 7.

[0039] Furthermore:

[0040] In an alternative embodiment, the injection tube 4 is a hollow cylinder, and the medicine spraying holes 5 communicate with the internal space of the injection tube 4.

[0041] In this embodiment: The injection tube 4 provided in a hollow shape can enable the medicament transmitted by the medicine tube 8 to enter its interior, and be injected through the medicine spraying holes 5 to the position between the lower baffle 3 and the upper baffle 7, so that the soil can be effectively repaired through the repair pile 1 and the medicine injection holes 2.

[0042] Furthermore:

[0043] In an alternative embodiment, threads are provided on both the outer surface and the inner surface of the adjusting screw 6.

[0044] In this embodiment: The adjusting screw 6 with threads provided on both the inner and outer surfaces can simultaneously form a threaded connection with the injection tube 4 and the repair pile 1. When the adjusting screw 6 rotates, the interval between the lower baffle 3 and the upper baffle 7 can change, enabling the soil at different depths to be subjected to the repair work.

[0045] The working principle and usage process of the present utility model: When it is necessary to repair the soil at a certain position, the repair pile 1 can be inserted into the soil. Subsequently, the heights of the lower baffle 3 and the upper baffle 7 can be adjusted according to the depth of the soil to be repaired. When adjusting the heights of the injection tube 4 and the upper baffle 7, the injection tube 4 can be rotated to generate rotation with the adjusting screw 6. At this time, the heights of the injection tube 4 and the upper baffle 7 will change. The space of the repair pile 1 below the upper baffle 7 is blocked by the upper baffle 7. When the adjusting screw 6 is rotated, the injection tube 4 can be controlled to keep its axial direction unchanged, while the adjusting screw 6 will rotate with the repair pile 1, driving the lower baffle 3 to slide on the inner surface of the repair pile 1 and realizing the height change. At this time, through the changes of the lower baffle 3 and the upper baffle 7, the flexible control of the soil repair position can be achieved. Finally, the repair agent can be injected into the hollow injection tube 4 through the medicine tube 8, and flow into the repair pile 1 through the medicine spraying holes 5 provided on the surface of the injection tube 4. Under the action of the lower baffle 3 and the upper baffle 7, the repair agent will be blocked between the two by the lower baffle 3 and the upper baffle 7, and finally injected into the soil to be repaired through the medicine injection holes 2 provided on the surface of the repair pile 1.

[0046] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
