Description

Technical Field

[0001] The invention belongs to the technical field of pollutant treatment engineering, and more specifically, relates to a compression frame for the construction of a vertical anti-seepage wall of a pollutant treatment tank and a construction method. Background Art

[0002] At present, the GCL composite barrier wall composed of geosynthetics clay liner (GCL) and backfill wall has become a new type of composite barrier, and its anti-seepage and anti-fouling performance is significantly improved compared with traditional barrier walls. There are more and more studies on anti-seepage, especially anti-seepage in chemical pollutant treatment sites, and anti-seepage has become a hot topic. The above composite barrier wall is used in the treatment of chemical pollutants and has good anti-seepage performance.

[0003] When the above-mentioned composite barrier wall is used in the treatment of chemical pollutants, the pollutants are stored in a barrier site covered with the GCL composite barrier wall. Existing chemical pollutant treatment sites are generally cylindrical troughs to facilitate the mixing of chemical pollutants and preparations and improve treatment efficiency. In the actual application of the composite barrier wall for chemical pollutants, previous research has mainly focused on horizontal waterproofing. However, vertical waterproofing is also an important aspect of waterproofing.

[0004] Vertical anti-seepage cannot copy the horizontal anti-seepage technology, because vertical anti-seepage involves the influence of the gravity of the barrier material. For example, how to lay the barrier material against the wall. In the horizontal plane, it is only necessary to ensure that the barrier material is laid flat. However, there are great technical difficulties in the vertical direction. The main problem is the gap between the barrier material and the inner wall of the chemical pollutant treatment site. This requires considering many factors such as the flatness of the fit between the barrier material and the chemical pollutant treatment site. At present, the research on vertical anti-seepage mainly focuses on rigid anti-seepage walls, plastic anti-seepage walls and flexible anti-seepage walls. However, both rigid anti-seepage walls and plastic anti-seepage walls have the disadvantages of high elastic modulus, high raw material consumption, high construction difficulty and cost, and long construction period. In the actual construction process, they are generally laid on the vertical inner wall and bottom of the chemical pollutant treatment site in the form of elastic GCL barrier blankets. After the above-mentioned GCL barrier blankets are covered on the vertical inner wall of the chemical pollutant treatment site, they need to be rolled along the circumferential direction of the vertical inner wall of the chemical pollutant treatment site through pressure rods to ensure that the GCL barrier blanket can fit the vertical inner wall, avoid gaps at the splicing positions of the GCL barrier blankets, and fail in some areas of the overlapping paste at the splicing positions of the GCL barrier blankets, thereby causing further seepage of pollutants.

[0005] After searching, patent CN221216927U discloses a telescopic boom machine, including a lifting section assembly, the lifting section assembly includes a fixed section and a lifting section, and the lifting section moves up and down along the fixed section. A lifting drive member, the output end of the lifting drive member is connected to the fixed section, and the lifting drive member is used to drive the lifting section to move. A swing cantilever, the end of the swing cantilever is hinged to the upper end of the lifting section. A swing drive assembly, the swing drive assembly includes a drum and at least one pull rope, one end of the pull rope is fixed to the drum, and the other end is fixed to the swing cantilever, the drum reels or unwinds the pull rope during the rotation along the axis, and the pull rope pulls the swing cantilever up and down to realize the switching of the swing cantilever between the horizontal and vertical states.

[0006] Patent CN221315345U discloses a lamination production tooling, including a workbench, on which a slide rail, a slide plate and a threaded rod are arranged through a mounting frame, a support plate and a roller are arranged at the bottom of the slide plate through a mounting shell, and a hydraulic rod, a lifting plate, a telescopic rod, a spring and a pressing plate are arranged on the workbench through a fixed plate, and an electric push rod is also arranged on the lifting plate, and a mounting plate is arranged at the end of the telescopic arm of the electric push rod. Under the action of the roller, the device can perform preliminary processing before lamination, thereby reducing the occurrence of internal bubbles affecting the lamination quality during lamination. In addition, the roller that can move up and down enables the device to better meet the needs of actual use and improves the applicability of the device. Under the action of the pressing plate, the film and object that need lamination can be pressed and fixed.

[0007] However, the above device cannot be applied to a processing chamber with an uneven surface, which may easily lead to damage of the GCL barrier blanket. Summary of the invention

[0060] The following detailed description of exemplary embodiments of the present invention refers to the accompanying drawings, which form a part of the description, and in which exemplary embodiments of the present invention that can be implemented are shown as examples. Although these exemplary embodiments are described in sufficient detail to enable those skilled in the art to implement the present invention, it should be understood that other embodiments can be implemented and various changes can be made to the present invention without departing from the spirit and scope of the present invention. The following more detailed description of the embodiments of the present invention is not intended to limit the scope of the claimed invention, but is only for the purpose of illustrating and not limiting the description of the characteristics and features of the present invention, so as to propose the best mode for performing the present invention and to enable those skilled in the art to implement the present invention. Therefore, the scope of the present invention is limited only by the appended claims.

[0061] It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention. As used herein, the terms "parallel" and "perpendicular" are not limited to their strict geometric definitions, but include tolerances for reasonable and inconsistent machining or human errors.

[0062] The following is combined with Figures 1 to 9 , the vertical anti-seepage wall construction compression frame of the pollutant treatment tank of the present invention is described in detail:

[0063] Example

[0064] A compacting frame for the construction of a vertical anti-seepage wall of a pollutant treatment tank, such as Figure 1-5 As shown, including:

[0065] Vertical pressing roller frame 200: used to achieve pressing in the vertical direction, the vertical pressing roller frame 100 is driven by a first driving unit;

[0066] Circumferential pressing roller frame 300: connected to the vertical pressing roller frame 100, used to achieve pressing at the circumferential position, and the circumferential pressing roller frame 100 is driven by the second driving unit;

[0067] The lifting mechanism 400 drives the vertical pressing roller frame 200 and the circumferential pressing roller frame 300 to move vertically;

[0068] The rotating mechanism drives the pressing frame to rotate.

[0069] The vertical pressing roller frame 200 is provided with a plurality of groups of vertical pressing rollers 210 , and the roller cores of the vertical pressing rollers 210 are horizontal and arranged along the circumferential direction of the processing chamber 100 .

[0070] The vertical pressing rollers 210 are distributed at equal angles along the circumferential direction of the vertical pressing roller frame 200 in a number of 4 to 6, preferably 6.

[0071] like Figure 3 and Figure 4 As shown, the vertical pressing roller frame 200 is provided with a flattening flexible brush 211, which is arranged on the outer side of the vertical pressing roller 210. The flattening flexible brush 211 is in the shape of a strip and extends along the circumferential direction of the processing chamber 100. The flattening flexible brush 211 is made of rubber material or other replaceable deformable materials. Under normal circumstances, it is in the shape of a straight strip. When the first stretching mechanism is started, the vertical pressing roller 210 abuts against the vertical inner wall of the processing chamber 100, and the flattening flexible brush 211 abuts against the inner wall of the processing chamber 100. Then the lifting mechanism 400 is started, so that the flattening flexible brush 211 rises and falls along the vertical inner wall of the processing chamber 100, flattens the GCL barrier blanket, and makes the GCL barrier blanket close to the vertical inner wall of the processing chamber 100.

[0072] Among them, the flattened flexible brushes 211 have different lengths, and the flattened flexible brushes 211 are arranged at intervals along the vertical direction of the processing chamber 100. To ensure that the GCL barrier blanket in the processing chamber 100 is fully covered by the flattened flexible brushes 211, the projections of the flattened flexible brushes 211 in the vertical direction have overlapping areas.

[0073] In one embodiment, the flattening flexible brush 211 extends in the horizontal direction, and each group of flattening flexible brushes 211 is arranged at intervals in the vertical direction, and the flattening flexible brushes 211 have overlapping parts in the vertical direction. After the first extending mechanism unfolds the vertical pressing roller 210, the flattening flexible brush 211 abuts against the vertical inner wall of the processing chamber 100, so that the flattening flexible brush 211 is deformed and abuts against the inner wall of the processing chamber 100, thereby ensuring that the flattening flexible brush 211 is in close contact with the inner wall of the processing chamber 100, ensuring the flattening effect on the GCL barrier blanket.

[0074] Specifically, the vertical pressing roller frame 200 includes a first lifting frame 230, the first lifting frame 230 is connected to the first stretching mechanism, the first driving unit is connected to the first stretching mechanism, and is used to drive the first stretching mechanism, and the vertical pressing roller 210 is connected to the first stretching mechanism, so that the vertical pressing roller 210 is driven in a radial direction to achieve the vertical pressing roller 210 approaching or moving away from the inner wall of the processing chamber 100.

[0075] Specifically, in order to realize the expansion and contraction of the vertical pressing roller 210, the first extension mechanism is as follows: Figure 6As shown, the first extension mechanism includes a first extension arm 220, and a plurality of first extension arms 220 are arranged in a circumferential direction of the processing chamber 100 at intervals. The vertical pressing roller 210 is rotatably mounted at the lower end of the first extension arm 220, and the upper end of the first extension arm 220 is hinged on the first lifting frame 230. The first extension arm 220 is connected to the first driving unit, and the first driving unit drives the first extension arm 220 to rotate around the hinge axis.

[0076] like Figure 6 As shown, the first driving unit includes a first driving arm 240 and a connecting arm 250 hinged to one end of the first driving arm 240, one end of the first driving arm 240 is hinged to the middle section of the first extension arm 220, and a vertical slide bar 251 is provided on the connecting arm 250, and the vertical slide bar 251 is vertically slidably set on the first driving disk 260, and a vertical spring 252 is sleeved on the vertical slide bar 251, and the upper end of the vertical spring 252 abuts against the first driving disk 260, and the lower end abuts against the connecting arm 250, and a first driving nut 261 is provided at the center of the first driving disk 260, and the first driving nut 261 cooperates with the first driving screw rod 262, and the upper end of the first driving screw rod 262 is rotatably mounted on the first lifting frame 230.

[0077] A first driven gear 2621 is provided at the upper end of the first driving screw rod 262 . The first driven gear 2621 cooperates with the first driving gear 2622 . The first driving gear 2622 is connected to the first driving motor 2623 . The first driving motor 2623 is installed on the first lifting frame 230 to realize the expansion and contraction of the vertical pressing roller 210 .

[0078] The first driving arm 240 is telescopically connected to the first driving disk 260 via a connecting arm 250, a vertical slide bar 251 and a vertical spring 252. Since the upper end of the first extension arm 220 is hinged to the first lifting frame 230, when the first extension mechanism drives the first driving disk 260 to move downward, the first driving arm 240 and the first extension arm 220 rotate around the hinge axis, so that the vertical pressing roller 210 is elastically tightly attached to the GCL barrier blanket on the inner wall of the processing chamber 100, and when encountering a flat position on the inner wall of the processing chamber 100, pressure loss on the inner wall of the processing chamber 100 is avoided.

[0079] The circumferential pressing roller frame 300 is provided with a plurality of groups of circumferential pressing rollers 310 .

[0080] The circumferential pressing roller frame 300 includes a second lifting frame 330, which is connected to the first lifting frame 230, and the second lifting frame 330 is connected to the second stretching mechanism. The second driving unit is connected to the second stretching mechanism and is used to drive the second stretching mechanism. The circumferential pressing roller 310 is connected to the second stretching mechanism, so that the circumferential pressing roller 310 is driven in the radial direction to achieve the approach or distance between the circumferential pressing roller 310 and the inner wall of the processing chamber 100.

[0081] Specifically, in order to realize the expansion or retraction of the circumferential pressing roller 320, the second extension mechanism includes a second extension arm 320, and the second extension arm 320 is arranged in a plurality of groups at intervals along the circumferential direction of the processing chamber 100. The circumferential pressing roller 310 is rotatably mounted at the lower end of the second extension arm 320, and the upper end of the second extension arm 320 is hinged on the second lifting frame 330. The second extension arm 320 is connected to the second driving unit, and the second driving unit drives the second extension arm 320 to rotate around the hinge axis.

[0082] like Figure 7 As shown, the circumferential pressing roller 310 is rotatably mounted on the roller frame 311, and the roller frame 311 is slidably mounted on the connecting roller frame 313 through a sliding rod 312. A spring 314 is sleeved on the sliding rod 312, and one end of the spring 314 abuts against the connecting roller frame 313, and the other end abuts against the roller frame 311. The connecting roller frame 313 is hinged to the lower end of the second extension arm 320.

[0083] Through the second unfolding mechanism, the circumferential pressing roller 310 is made to abut against the vertical inner wall of the processing chamber 100. Through the compression spring 314, the circumferential pressing roller 310 is made to elastically abut against the vertical inner wall of the processing chamber 100. The connecting roller frame 313 is hinged to the lower end of the second extension arm 320, so that the circumferential pressing roller 310 can adaptively abut against the inner wall of the processing chamber 100. When the verticality of the processing chamber 100 changes, the roller body of the circumferential pressing roller 310 can always abut against the vertical inner wall of the processing chamber 100, thereby ensuring the pressing effect on the GCL barrier blanket.

[0084] Furthermore, the second extension arm 320 is provided with two groups of limit rods 321, which are arranged horizontally, and the connecting roller frame 313 is arranged between the two groups of limit rods 321, which can realize the limiting of the angle of the connecting roller frame 313 at the lower end of the second extension arm 320.

[0085] like Figure 6As shown, the second driving unit includes a second driving arm 340, one end of the second driving arm 340 is hinged to the middle section of the second extension arm 320, and the other end of the second driving arm 340 is hinged to the second driving disk 350, and a second driving nut 351 is arranged at the center of the second driving disk 350, and the second driving nut 351 cooperates with the second driving screw rod 352, and the second driving screw rod 352 is coaxial with the first driving screw rod 262.

[0086] A second driven gear 3521 is disposed at the upper end of the second driving screw rod 352 . The second driven gear 3521 cooperates with the second driving gear 3522 . The second driving gear 3522 is connected to the second driving motor 3523 . The second driving motor 3523 is installed on the first lifting frame 230 .

[0088] Specifically, Figure 5 As shown, the lifting frame 410 is provided with at least two groups of lifting wheels 430 , preferably four groups, and the first lifting frame 230 is provided with a lifting cable 420 , which is passed through the lifting wheels 430 to lift the first lifting frame 230 .

[0089] Through multiple sets of lifting wheels 430 and lifting cables 420, the entire pressing frame can be lifted smoothly to avoid tilting of the pressing frame. The lifting unit includes a pulley group of the prior art, which can realize the extension and retraction of the lifting cables 420, thereby lifting or releasing the lifting frame.

[0090] In order to realize the rotation of the pressing frame, the lifting mechanism 400 is connected to the rotating mechanism, and the rotating mechanism includes a rotating disk 510. The hanging wheel 430 is fixed on the rotating disk 510. The rotating disk 510 is rotatably installed on the lifting frame 410. The power motor and other equipment used for lifting are installed on the rotating disk 510. The lifting frame 410 is provided with a stepping motor, which can implement the slow rotation of the rotating disk 510 to ensure the rotation of the pressing frame and the slow rotation of the pressing frame.

[0091] In order to achieve a tight combination of the GCL barrier blanket in the processing chamber 100, a compression strip 600 is provided at the splicing position of the GCL barrier blanket along the circumference of the inner wall of the processing chamber 100, such as Figure 8-9As shown, the clamping strip 600 is in the shape of a card slot as a whole and a guide rail 620 is provided at the extended end. The guide rail 620 is in the shape of an "eight" as a whole. An anchor 610 is provided on the guide rail 620. After the clamping frame is lowered to the lower end position of the processing chamber 100 by the lifting mechanism 400, the vertical pressing roller 210 extends into the guide rail 620. As the lifting mechanism 400 drives the clamping frame, the vertical pressing roller 210 extends into the card slot of the clamping strip 600, so that the anchor 610 penetrates the overlapping area of ​​the GCL barrier blanket, thereby realizing the tight combination of the GCL barrier blanket at the joint.

[0092] During the actual construction process, the processing chamber 100 is mainly used to process chemical pollutants, and its depth reaches 10 to 15 meters and its diameter is between 10 and 12 meters.

[0093] The present application uses a lifting mechanism 400 to hoist the pressing frame to the bottom of the processing chamber 100. First, by starting the first stretching mechanism, the vertical pressing roller 210 is abutted against the vertical inner wall of the processing chamber 100. As the vertical pressing roller frame 200 moves up and down, the splicing position of the GCL barrier blanket is pressed. By starting the second stretching mechanism, the circumferential pressing roller 310 is abutted against the vertical inner wall of the processing chamber 100. By starting the rotating mechanism and the lifting mechanism 400, the circumferential pressing roller frame 300 is rotated and moved up and down. As the circumferential pressing roller frame 300 moves up and down, the GCL barrier blanket is pressed along the circumferential direction of the vertical inner wall of the processing chamber 100 to ensure that the GCL barrier blanket is in close contact with the vertical inner wall of the processing chamber 100, so as to implement sealing and bonding of the joint position between the GCL barrier blankets, and ensure the reliability of the anti-seepage construction of the vertical wall of the entire processing chamber 100.

[0094] A method for constructing a vertical anti-seepage wall of a pollutant treatment tank, the method uses the above-mentioned pressing frame to construct a vertical anti-seepage wall of the pollutant treatment tank, and the method comprises the following steps:

[0095] S101: performing anti-seepage treatment on the bottom surface of the processing chamber 100, and laying a GCL barrier blanket flat on the bottom surface of the processing chamber 100;

[0096] S102: releasing the GCL barrier blanket at one end of the coil from the upper end of the processing chamber 100 to the bottom surface, applying overlapping paste on the GCL barrier blanket so that one end of the GCL barrier blanket is bonded to the GCL barrier blanket on the bottom surface of the processing chamber 100, and applying overlapping paste on the side of the GCL barrier blanket so that the GCL barrier blankets are adhered together and there are overlapping areas between the GCL barrier blankets;

[0097] S103: Arrange the compression strips 600 along the circumference of the processing chamber 100, and make the compression strips 600 pressed outside the overlapping area of ​​the GCL barrier blanket;

[0098] S104: Use the lifting mechanism 400 to hoist the compression frame to the position below the processing chamber 100, start the first extension mechanism so that the vertical pressing roller 210 is pressed against the outside of the compression bar 600, start the lifting mechanism 400 to make the compression frame rise, and the anchor pins 610 on the compression bar 600 penetrate the overlapping area of ​​the GCL barrier blanket.

[0099] like Fig. 9 As shown, a clamping strip 600 is provided on the circumference of the inner wall of the processing chamber 100. The clamping strip 600 is in the shape of a card slot as a whole and a guide track 620 is provided at the extended end. The guide track 620 is in the shape of an "eight" as a whole. An anchor 610 is provided on the guide track 620. After the clamping frame is lowered to the lower end position of the processing chamber 100 by the lifting mechanism 400, the vertical pressing roller 210 extends into the guide track 620. As the lifting mechanism 400 drives the clamping frame, the vertical pressing roller 210 extends into the card slot of the clamping strip 600, and then one end of the anchor 610 is squeezed, so that the anchor 610 penetrates the overlapping area of ​​the GCL barrier blanket.

[0100] S105: Start using the lifting mechanism 400 to lift the pressing frame to the position below the processing chamber 100, start the second stretching mechanism to press the circumferential pressing roller 310 against the inner wall of the processing chamber 100, start the rotating mechanism and the lifting mechanism 400 to move the circumferential pressing roller 310 along the circumferential direction and vertical direction of the inner wall of the processing chamber 100, so that the GCL barrier blanket is tightly attached to the inner wall of the processing chamber 100.
