Description

Technical Field

[0001] The present invention relates to the field of environmental management, and in particular to a pressure relief pipe for soil remediation that is easy to assemble. Background Art

[0002] As human production and life intensify, the damage to the surrounding environment is becoming more and more serious, among which soil pollution is particularly serious. Therefore, the remediation of contaminated soil is imminent.

[0003] At present, when repairing contaminated soil, a common method is to add chemicals to the soil to achieve the purpose of repair. However, when the amount of additives used exceeds the standard, it will in turn affect the soil quality, thereby affecting the repair effect. Therefore, in the existing technology, when repairing the soil, a pressure relief pipe is inserted into the soil, and then an aeration device is used. The high-pressure gas generated by the air compressor is injected into the soil through the aeration pipe. The organic pollutants in the soil will flow with the high-pressure gas, flow to the pressure relief pipe, and be discharged through the pressure relief pipe to achieve the purpose of repairing the soil. However, the structure of the pressure relief pipe in the existing technology is too simple, and the pressure relief holes on its surface are easily blocked by the soil in the process of the pressure relief pipe entering the soil, thereby affecting the subsequent release of gas. At the same time, when burying multiple pressure test pipes, the one-by-one burial method also has the problem of low efficiency. For this reason, this solution proposes a pressure relief pipe for soil repair that is easy to assemble. Summary of the Invention

A plurality of insert rods are fixed to the top surface of the connecting ring. The inner ring of the connecting ring matches the outer periphery of the tube body, and a locking bolt is screwed onto the outer periphery of the connecting ring. A plurality of air holes matching the pressure relief holes are opened on the outer periphery of the protective tube, and the outer periphery of the protective tube matches the inner ring of the tube body.

[0008] The pipe burying mechanism includes a mounting plate, a plurality of connecting components mounted on the mounting plate, and a driving component for driving the plurality of connecting components to rotate.

[0011] Through the above technical solution, when the protective tube is not compressed, the air holes on the protective tube and the pressure relief holes on the tube body are in a state of overlap, and when compressed by external force, the air holes are staggered with the pressure relief holes, thereby preventing soil from entering the inside of the tube body through the pressure relief holes when the pressure relief mechanism enters the ground.

[0012] As a further improvement of the above solution, a plurality of positioning blocks are fixed to the inner ring of the connecting ring, and the positioning blocks cooperate with the tube body.

[0021] Through the above technical solution, the position of the gear ring can be easily adjusted to adapt to different embedding densities.

[0022] As a further improvement of the above solution, the top of the tube body and the top inner circle of the protective tube are both provided with internal threads, and the bottom outer periphery of the tube body and the bottom outer periphery of the protective tube are both provided with external threads matching the internal threads.

[0034] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0035] Example 1:

[0036] Please combine Figure 1 , this embodiment includes a pressure relief mechanism, which includes an outer tube and an inner tube. The outer tube includes a tube body 1 and a spiral drill rod 3 installed at the bottom of the tube body 1. A plurality of pressure relief holes 2 are opened on the outer periphery of the tube body 1. The pressure relief holes 2 are evenly distributed on the outer periphery of the tube body 1. The top inner ring of the tube body 1 is provided with an internal thread, and the bottom outer periphery of the tube body 1 is provided with an external thread matching the internal thread, so that the length of the tube body 1 can be changed according to the depth of the construction site. When the depth is large, multiple tube bodies 1 can be connected for use.

[0037] The inner tube includes a protective tube 7 inserted into the inner side of the tube body 1, a connecting ring 4 fixedly installed on the outer periphery of the protective tube 7 by an elastic member, and a magnet 5 fixed on the top surface of the connecting ring 4. The top inner ring of the protective tube 7 is provided with an internal thread, and the bottom outer periphery of the protective tube 7 is provided with an external thread matching the internal thread. The number of protective tubes 7 is matched according to the appropriate amount of tube body used. A plurality of insertion rods 6 are fixed on the top surface of the connecting ring 4. The inner ring of the connecting ring 4 matches the outer periphery of the tube body 1, and a locking bolt 15 is screwed on the outer periphery of the connecting ring 4. A plurality of air holes 14 matching the pressure relief holes 2 are provided on the outer periphery of the protective tube 7, and the outer periphery of the protective tube 7 matches the inner ring of the tube body 1. The number of elastic members is set to 2 to 3, and the plurality of elastic members are equidistantly distributed on the outer periphery of the protective tube 7. The elastic members include a mounting block 11 fixed on the outer periphery of the protective tube 7, a mounting block 11 fixed on the bottom of the mounting block 11 The buffer column on the surface, the spring 12 and the limit block 13 movably sleeved on the outer circumference of the buffer column, one end of the limit block 13 is fixed on the inner ring of the connecting ring 4, and the spring 12 is located between the limit block 13 and the mounting block 11. After the protective tube 7 is inserted into the inner side of the tube body 1, the connecting ring 4 is sleeved on the outer circumference of the tube body 1, and then the locking bolt 15 is tightened so that one end of the locking bolt 15 abuts against the outer wall of the tube body 1, and then the connecting ring 4 can be locked on the tube body 1. The arrangement of the elastic part is so that when the protective tube 7 is not squeezed, the air vent 14 on the protective tube 7 is in a state of overlap with the pressure relief hole 2 on the tube body 1, and after being squeezed by external force, it is staggered with the pressure relief hole 2, thereby preventing soil from entering the inside of the tube body 1 from the pressure relief hole 2 when the pressure relief mechanism enters the ground, and also well avoiding the blockage of the pressure relief hole 2.

[0038] The inner ring of the connecting ring 4 is fixed with multiple positioning blocks 17, and the positioning blocks 17 cooperate with the tube body 1. When installing the protective tube 7, when the positioning blocks 17 touch the top of the tube body 1, it means that the protective tube 7 has reached the accurate installation position, and then you only need to tighten the locking bolts 15.

[0039] The outer periphery of the protective tube 7 is provided with a slide groove 10 arranged along its length direction, a fixing block 8 is fixed in the slide groove 10, and a limiting column 9 arranged along the length direction of the slide groove 10 is fixed to the bottom surface of the fixing block 8. A fixing sleeve 16 that matches the limiting column 9 is fixed on the inner wall of the tube body 1. When the outer tube is composed of multiple tube bodies 1 connected together, during the installation of the protective tube 7, the limiting column 9 is inserted into the fixing sleeve 16 to prevent the adjacent tube bodies 1 from loosening during the rotation of the outer tube.

[0040] The implementation principle of this embodiment is as follows: before burying the pressure relief mechanism, the length of the pipe body 1 is first changed according to the depth of the construction site. When the depth is large, multiple pipe bodies 1 can be connected and used. At the same time, the number of protective pipes 7 is also changed accordingly according to the number of pipe bodies 1.

[0041] When the pressure relief mechanism is in operation, it is only necessary to insert the protective tube 7 into the tube body 1, and then locate the block 17. When it touches the top of the tube body 1, it means that the protective tube 7 has reached the accurate installation position. After that, it is only necessary to tighten the locking bolt 15 to complete the assembly of the pressure relief mechanism. Then, when burying the pressure mechanism into the soil, press the protective tube 7 down so that the air vent 14 is staggered with the pressure relief hole 2. After the burial is completed, remove the pressure applied to the protective tube 7, so that the protective tube 7 returns to its original position, so that the air vent 14 is aligned with the pressure relief hole 2, so that the gas in the soil can enter the protective tube 7 from the pressure relief hole 2 through the air vent, and finally be discharged from the protective tube 7.

[0042] Example 2:

[0043] Combine Figure 4-5, based on Example 1, this embodiment is further improved in that: it also includes a pipe burying mechanism, which includes a mounting plate 18, a plurality of connecting components mounted on the mounting plate 18, and a driving component for driving the plurality of connecting components to rotate. The top surface of the mounting plate 18 is provided with a plurality of mounting grooves 30 for installing the connecting components. The connecting components include a moving block 27 slidingly connected in the mounting groove 30, a rotating shaft 25 rotatably connected to the bottom surface of the moving block 27, and a connecting plate 29 fixed to the rotating shaft 25. The inner wall of the long side of the mounting groove 30 is provided with a limiting groove 26 arranged along its length direction, and the outer wall of one side of the connecting plate 29 is fixed A limiting block, one end of the limiting block extends into the limiting groove 26 and slides therewith, a magnet 2 is installed on the bottom surface of the connecting plate 29, and a plurality of sockets 28 that match the plug rod 6 are opened on the bottom surface of the connecting plate 29, and a locking piece for locking the moving block 27 is also installed in the mounting groove 30. The top of the rotating shaft 25 extends above the mounting groove 30 and is fixed with a transmission gear 24 that is connected to the drive assembly. The mounting groove 30 is arranged along the radial direction of the mounting disk 18, and the mounting groove 30 is provided with a through hole on one side away from the center of the mounting disk 18. The locking piece includes an adjusting column 33 movably arranged in the through hole and a fixed screw threaded on the bottom surface of the mounting disk 18. Bolt, one end of the adjusting column 33 extends into the mounting groove 30 and is fixed to the outer wall of the moving block 27, and the other end of the adjusting column 33 extends to the outside of the mounting plate 18. The driving assembly includes a turntable 19 rotatably connected to the top surface of the mounting plate 18, a plurality of telescopic columns fixed to the outer periphery of the turntable 19, and a gear ring 32 fixed to the end of the telescopic column away from the turntable 19. The turntable 19 is coaxially arranged with the mounting plate 18, and a fixed shaft 20 is fixed to the top surface of the turntable 19. A mounting frame 31 is also installed on the top surface of the mounting plate 18. The gear ring 32 cooperates with the transmission gear 24. When burying the pressure relief mechanism, first install the assembled pressure relief mechanisms separately. When installing on the connecting plate 29 of multiple connecting components, the insertion rod 6 on the top of the connecting ring 4 is aligned with the insertion hole 28 on the bottom surface of the connecting plate 29, and the magnet 1 5 on the top surface of the connecting ring 4 is adsorbed with the magnet 2 on the bottom surface of the connecting plate 29, so that the protective tube 7 in the pressure relief mechanism is squeezed, so that the air vent 14 and the pressure relief hole 2 are staggered. In this way, when the pressure relief mechanism enters the soil, the soil will not enter the inside of the tube body 1 through the pressure relief hole 2. After that, the gear ring 32 and the transmission gear 24 are adjusted to be able to engage with each other, so that multiple pressure relief mechanisms can be driven to rotate simultaneously during the rotation of the turntable 19.

[0044] The mounting groove 30 is arranged along the radial direction of the mounting plate 18, and a through hole is opened on the side of the mounting groove 30 away from the center of the mounting plate 18. The locking member includes an adjusting post 33 movably arranged in the through hole and a fixing bolt screwed to the bottom surface of the mounting plate 18. One end of the adjusting post 33 extends into the mounting groove 30 and is fixedly connected to the outer wall of the movable block 27, and the other end of the adjusting post 33 extends to the outside of the mounting plate 18, and the outer periphery of the adjusting post 33 is marked with a scale value. The moving distance of the movable block 27 can be accurately adjusted by adjusting the scale value on the adjusting post, and the distance between adjacent pressure release mechanisms or the density of the pressure applying mechanisms can be adjusted by adjusting the position of the movable block 27. When adjusting, the fixing bolt is loosened, and then the movable block 27 can be pushed. After the adjustment is completed, the fixing bolt is tightened so that one end of the fixing bolt is pressed against the outer periphery of the adjustment 33, thereby relying on the friction between the fixing bolt and the outer periphery of the adjusting post 33 to lock the adjusting post 33.

[0045] The telescopic column includes a fixed cylinder 21 fixed to the outer periphery of the turntable 19, a movable column 23 movably sleeved in the fixed cylinder 21 and a positioning bolt 22 threadedly connected to the top surface of the fixed cylinder 21. One end of the movable column 23 is fixedly connected to the inner ring of the gear ring 32, and one end of the positioning bolt 22 abuts against the outer periphery of the movable column 23. The outer periphery of the movable column 23 is marked with scale values, so that the length of the telescopic column can be accurately adjusted. During adjustment, the length of each telescopic column is ensured to be consistent, so that after the turntable 19 rotates, each gear ring 32 can drive the transmission gear 24 to rotate.

[0046] The implementation principle of this embodiment is as follows: when using the buried pipe mechanism, the burial density of the pressure relief mechanism is first determined. After the determination is completed, the position of the connecting mechanism on the mounting plate 18 is adjusted accordingly. When adjusting, the fixing bolts are first loosened, and then the movable block 27 is adjusted. The position of the movable block is determined according to the scale value on the adjusting column 33. After the adjustment is completed, the fixing bolts are tightened. Then the position of the gear ring 32 is adjusted. When adjusting, the positioning bolts 22 are first loosened, and then the length of the telescopic column is adjusted so that the gear ring 32 can be engaged with the transmission gear 24. Then the positioning bolts 22 are tightened. Then the pressure relief mechanisms are installed one by one on the connecting plates 29 of the multiple connecting components. Finally, the turntable 19 is driven to rotate. After the turntable 19 rotates, the gear ring 32 can be driven to rotate. After the gear ring 32 is engaged with the transmission gear 24, it can be driven to rotate, thereby simultaneously driving multiple pressure relief mechanisms to rotate, so that multiple pressure relief mechanisms can be buried in the soil at the same time.

[0047] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
