[0015] According to some embodiments of the present invention, the outer diameter of the top end of the tapered portion is equal to or greater than the outer diameter of the tube unit.
[0016] The in-situ repair drug delivery device according to a second aspect of the present invention includes a frame, an in-situ repair drug delivery component as described in the first aspect of the present invention, and a drive component.

[0036] The following is for reference. Figures 1 to 3 This invention describes an in-situ repair drug delivery component and a drug delivery device according to embodiments of the present invention.
[0037] According to the first aspect of the present invention, the in-situ repair drug delivery component 10, such as Figures 1 to 3 As shown, it includes a dosing sleeve 100 and a dosing hose 200.
[0038] The dosing sleeve 100 includes multiple tube units 101, which are arranged sequentially along the length of the dosing sleeve 100. Adjacent tube units 101 are hinged to each other. For example, the multiple tube units 101 can be arranged vertically. The uppermost tube unit 101 can be longer and can be installed vertically on the frame 20 of the in-situ repair dosing device. The remaining tube units 101 can be shorter, and the hinge axis between two adjacent tube units 101 is perpendicular to the length of the dosing sleeve 100. Two adjacent tube units 101 can swing relative to each other around the corresponding hinge axis.
[0039] The dosing hose 200 is installed in the dosing sleeve 100. The top end of the dosing hose 200 can be connected to the chemical tank. The dosing hose 200 is used to deliver the remediation agent and inject the remediation agent into the formation through the bottom end of the dosing hose 200.
[0040] In this invention, the dosing sleeve 100 of the in-situ repair dosing component 10 is vertically mounted on the dosing device, and the dosing hose 200 can be connected to the reagent tank. When it is necessary to inject repair agent into the formation, the in-situ repair dosing component 10 is moved downwards, the dosing sleeve 100 is inserted into the corresponding area of the formation, and the repair agent can be injected through the dosing hose 200.
[0041] According to the in-situ remediation drug delivery component 10 of this utility model embodiment, the drug delivery sleeve 100 includes multiple tube units 101, and two adjacent tube units 101 are hinged to each other. In this way, when obstacles such as rocks or ground subsidence occur during the penetration of the stratum, the two adjacent tube units 101 can be relatively tilted, and can be inserted obliquely to the periphery of the obstacle area to avoid the obstacle area. This allows the drug delivery sleeve 100 to penetrate the corresponding area of the stratum more smoothly, which is more conducive to the addition of remediation agents.
[0042] refer to Figure 2 As shown, in some embodiments of this utility model, a hinge structure 300 is provided between two adjacent pipe units 101. The hinge structure 300 includes a hinge member 301, which is hinged to the two adjacent pipe units 101 respectively. For example, the two ends of the hinge member 301 can be respectively attached to the same side of the two adjacent pipe units 101, and the hinge axes between the hinge member 301 and the two adjacent pipe units 101 can be parallel to each other. In this way, the two adjacent pipe units 101 can swing relative to the hinge member 301 between them, thereby realizing the relative swing between the two adjacent pipe units 101. The structure is simple, and the relative swing effect between the two adjacent pipe units 101 is better, which allows the dosing sleeve 100 to penetrate into the corresponding area of the formation more smoothly, which is more conducive to the addition of remediation agents.
[0043] refer to Figure 2 As shown, in some embodiments of this utility model, hinge shafts 302 are respectively installed between the hinge member 301 and two adjacent pipe units 101, and the two hinge shafts 302 on the same hinge member 301 are parallel to each other. For example, the two hinge shafts 302 corresponding to the same hinge member 301 can be fixedly installed on the same side of two adjacent pipe units 101, and the two ends of the hinge member 301 can be rotatably sleeved on the two hinge shafts 302. Of course, the two hinge shafts 302 corresponding to the same hinge member 301 can also be fixedly installed on the two ends of the hinge member 301, and the two hinge shafts 302 can be rotatably connected to the same side of two adjacent pipe units 101. In addition, the hinge shafts 302 can also be rotatably connected to both the hinge member 301 and the pipe unit 101.
[0044] In this embodiment, hinge shafts 302 are respectively installed between the hinge member 301 and two adjacent pipe units 101. The two hinge shafts 302 on the same hinge member 301 are parallel to each other. This makes the relative swing between the two adjacent pipe units 101 smoother and more convenient, and the relative swing effect between the two adjacent pipe units 101 is better. This allows the dosing sleeve 100 to penetrate into the corresponding area of the formation more smoothly, which is more conducive to the addition of the remediation agent.
[0045] refer to Figure 2 As shown, in some embodiments of this utility model, the hinge structure 300 includes two hinge members 301. The two hinge members 301 of the same hinge structure 300 are located on opposite sides of the pipe unit 101, and the hinge shaft 302 between the pipe unit 101 and the two hinge members 301 of the same hinge structure 300 is coaxially arranged. In this embodiment, two adjacent pipe units 101 are hinged to each other through two hinge members 301, and the two hinge members 301 of the same hinge structure 300 are located on opposite sides of the pipe unit 101. In this way, the connection structure between two adjacent pipe units 101 has higher strength, more stable connection, and longer service life.
[0046] refer to Figure 2 As shown, in some embodiments of this utility model, among the multiple tube units 101, the hinge shafts 302 at both ends of the middle tube unit 101 are perpendicular to each other. For example, when the hinge shaft 302 at the top of the middle tube unit 101 extends in the left-right direction, the hinge shaft 302 at the bottom of the middle tube unit 101 can extend in the front-back direction; when the hinge shaft 302 at the top of the middle tube unit 101 extends in the front-back direction, the hinge shaft 302 at the bottom of the middle tube unit 101 can extend in the left-right direction. In this embodiment, the hinge shafts 302 at both ends of the middle tube unit 101 are perpendicular to each other. Thus, among the three adjacent tube units 101, the lowermost tube unit 101 can be tilted relative to the uppermost tube unit 101 in two mutually perpendicular directions. Therefore, when obstacles such as rocks or ground subsidence occur during the penetration of the stratum, the lowermost tube unit 101 can be inserted obliquely to more directions around the obstacle area to avoid the obstacle area. This allows the dosing sleeve 100 to penetrate the stratum more smoothly and is more conducive to the addition of the repair agent.
[0047] refer to Figure 2 As shown, in some embodiments of this utility model, when two adjacent tube units 101 are coaxial, there is a gap between the two adjacent tube units 101, and after the two adjacent tube units 101 rotate relative to each other by a preset angle, the adjacent ends on the same side of the two adjacent tube units 101 abut together. In this embodiment, when two adjacent tube units 101 are coaxial, there is a gap between the two adjacent tube units 101. This facilitates the relative swinging of the two adjacent tube units 101 by a preset angle, and after the two adjacent tube units 101 swing relative to each other by a preset angle, the adjacent ends on the same side of the two adjacent tube units 101 abut together, which can prevent the two adjacent tube units 101 from continuing to swing relative to each other.
[0048] In this embodiment, this configuration allows for relative swaying between two adjacent pipe units 101, while also preventing excessive relative swaying angles between the two adjacent pipe units 101 that could affect penetration into the formation. This allows the dosing sleeve 100 to penetrate the formation more smoothly, which is more conducive to the addition of remediation agents.
[0049] refer to Figure 3 As shown, in some embodiments of this utility model, the in-situ remediation dosing assembly 10 further includes a liquid outlet head 400. The liquid outlet head 400 is plugged at the bottom end of the lowest tube unit 101, and the liquid outlet head 400 has a liquid outlet hole 401. The bottom end of the dosing hose 200 is connected to the liquid outlet head 400. In this embodiment, the liquid outlet head 400 can block the bottom end of the lowest tube unit 101, thereby preventing soil from entering the dosing sleeve 100 and damaging the dosing hose 200 during the process of penetrating the formation, and preventing the dosing sleeve 100 from continuing to penetrate the formation, so that the dosing sleeve 100 can penetrate the formation more smoothly, which is more conducive to the addition of remediation agents.
[0050] refer to Figure 3 As shown, in some embodiments of this utility model, the top end of the liquid outlet head 400 is inserted into the lowest tube unit 101, the bottom end of the liquid outlet head 400 protrudes from the lowest tube unit 101 and forms a tapered portion 402, the outer diameter of the tapered portion 402 gradually decreases from top to bottom, and the liquid outlet hole 401 has multiple holes and is provided on the side wall of the tapered portion 402. For example, the top of the liquid outlet head 400 can be welded to the bottommost pipe unit 101 after being inserted into it, so that the sealing effect of the bottommost pipe unit 101 is better. Moreover, the bottom end of the liquid outlet head 400 protrudes from the bottommost pipe unit 101 and forms a conical part 402. The side wall of the conical part 402 is provided with multiple liquid outlet holes 401, so that the repair agent can be discharged from multiple directions through multiple liquid outlet holes 401, resulting in better liquid discharge effect and better repair effect on the formation. In addition, the outer diameter of the conical part 402 gradually decreases from top to bottom, so that the chemical dosing sleeve 100 experiences less resistance during the process of penetrating the formation, making it easier for the chemical dosing sleeve 100 to penetrate the formation and more conducive to the addition of repair agents.
[0051] refer to Figure 3 As shown, in some embodiments of this utility model, the outer diameter of the top end of the tapered portion 402 is equal to or greater than the outer diameter of the tube unit 101. This further reduces the resistance encountered by the dosing sleeve 100 during its insertion into the formation, allowing it to penetrate the formation more smoothly and facilitating the addition of remedial agents.
[0052] refer to Figure 1As shown, the dosing device according to the second aspect of the present invention includes a frame 20, an in-situ repair dosing component 10 as described in the first aspect of the present invention, and a drive component 30. The in-situ repair dosing component 10 is vertically and flexibly mounted on the frame 20, and the drive component 30 is mounted on the frame 20 to drive the in-situ repair dosing component 10 to move up and down.
[0053] For example, refer to Figure 1 As shown, a sliding lifting platform can be installed on the frame 20. The uppermost pipe unit 101 of the dosing sleeve 100 can be connected to the lifting platform. The driving component 30 can be a motor screw mechanism or a hydraulic cylinder, etc. The driving component 30 is located on the frame 20 and is connected to the lifting platform to drive the lifting platform to rise and fall, thereby driving the in-situ repair dosing assembly 10 to rise and fall. When it is necessary to inject repair agent, the driving component 30 drives the dosing sleeve 100 of the in-situ repair dosing assembly 10 to fall through the lifting platform, so that the dosing sleeve 100 can penetrate into the formation and inject the repair agent. After the dosing is completed, the driving component 30 drives the dosing sleeve 100 of the in-situ repair dosing assembly 10 to rise through the lifting platform.
[0054] According to the dosing device of the present invention, by adopting the in-situ repair dosing component 10 of the first aspect of the present invention, the dosing sleeve 100 includes a plurality of tube units 101, and two adjacent tube units 101 are hinged to each other. In this way, when obstacles such as rocks or ground collapse occur during the penetration of the stratum, the two adjacent tube units 101 can be relatively tilted, and can be inserted obliquely to the periphery of the obstacle area to avoid the obstacle area. This allows the dosing sleeve 100 to penetrate the corresponding area of the stratum more smoothly, which is more conducive to the addition of repair agents.
[0055] It should be noted that since the dosing device can adopt all the technical solutions of the in-situ repair dosing component 10 of the first aspect embodiment, it has at least all the beneficial effects brought about by the technical solutions of the first aspect embodiment. These additional beneficial effects will not be elaborated here.
[0056] It is understood that other components and operations of the dosing device according to the embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
[0057] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
