Description

Technical Field

[0001] This invention belongs to the field of pollutant treatment engineering technology, and more specifically, relates to a construction clamping frame and construction method for a vertical anti-seepage wall of a pollutant treatment tank. Background Technology

[0002] Currently, GCL composite barrier walls, consisting of geosynthetic clay liners (GCLs) and backfill walls, have become a novel type of composite barrier, offering significantly improved seepage and pollution prevention performance compared to traditional barrier walls. Research on seepage prevention, especially in chemical pollutant treatment plants, is increasing, making seepage control a hot topic. The aforementioned composite barrier walls demonstrate good seepage prevention properties when applied to the treatment of chemical pollutants.

[0003] When the aforementioned composite barrier wall is applied to the treatment of chemical pollutants, the pollutants are stored in the barrier area covered by 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 practical applications, previous studies on the composite barrier wall for chemical pollutants have mainly focused on horizontal seepage prevention. However, vertical seepage prevention is also an important aspect of seepage prevention.

[0004] Vertical seepage control cannot simply replicate horizontal seepage control techniques because it involves the influence of the barrier material's gravity. For example, how to ensure the barrier material adheres to the wall is crucial. In a horizontal plane, simply ensuring the material is laid flat is sufficient; however, laying it flat in a vertical direction presents significant technical challenges, primarily due to gaps between the barrier material and the inner wall of the chemical pollutant treatment plant. This necessitates considering many factors, including the flatness and adhesion between the barrier material and the treatment plant. Current research on vertical seepage control mainly focuses on rigid, plastic, and flexible seepage control walls. However, both rigid and plastic cutoff walls have drawbacks such as high elastic modulus, high raw material consumption, high construction difficulty and cost, and long construction period. In actual construction, elastic GCL barrier blankets are generally laid on the vertical inner wall and bottom of the chemical pollutant treatment site. After the GCL barrier blanket is covered on the vertical inner wall of the chemical pollutant treatment site, it needs to be rolled along the circumferential direction of the vertical inner wall by a pressure bar to ensure that the GCL barrier blanket can fit the vertical inner wall and avoid gaps at the splicing points of the GCL barrier blanket. This prevents the overlap of the GCL barrier blanket at the splicing points from failing and causing further leakage of pollutants.

[0005] A search revealed that patent CN221216927U discloses a telescopic cantilever machine, including a lifting section assembly. The lifting section assembly includes a fixed section and a lifting section, which can move up and down along the fixed section. A lifting drive component, the output end of which is connected to the fixed section, drives the lifting section to move. A swing cantilever, the end of which is hinged to the upper end of the lifting section. A swing drive assembly includes a roller and at least one pull rope. One end of the pull rope is fixed to the roller, and the other end is fixed to the swing cantilever. As the roller rotates along its axis, it winds up or unwinds the pull rope, which pulls the swing cantilever to swing up and down, thus switching the swing cantilever between horizontal and vertical states.

[0006] Patent CN221315345U discloses a film pressing production fixture, including a worktable. The worktable is equipped with a slide rail, a slide plate, and a threaded rod via a mounting frame. A support plate and a rotating roller are mounted on the bottom of the slide plate via a mounting shell. The worktable also has a hydraulic rod, a lifting plate, a telescopic rod, a spring, and a pressing plate mounted via a fixed plate. An electric push rod is mounted on the lifting plate, and a mounting plate is attached to the end of the telescopic arm of the electric push rod. This device, under the action of the rotating roller, allows for preliminary processing before film pressing, thereby reducing the impact of internal air bubbles on the film pressing quality. Furthermore, the vertically movable rotating roller allows the device to better meet practical needs and improve its applicability. Under the action of the pressing plate, the film and object to be pressed can be pressed and fixed.

[0007] However, the above-mentioned device is not suitable for processing cavities with uneven surfaces, which can easily lead to damage to the GCL barrier blanket. Summary of the Invention

[0027] Furthermore, the second extension arm is provided with two sets of limiting rods, which are arranged horizontally.

[0040] 3. Beneficial effects

[0041] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0042] (1) The pressing frame of the present invention, by activating the first extension mechanism, makes the vertical pressing roller abut against the vertical inner wall of the treatment chamber. As the vertical pressing roller frame moves up and down, it presses the splicing position of the GCL barrier blanket. By activating the second extension mechanism, it makes the circumferential pressing roller abut against the vertical inner wall of the treatment chamber. By activating the rotation mechanism and the lifting mechanism, it makes the circumferential pressing roller frame move up and down in a rotating manner. As the circumferential pressing roller frame moves up and down, it presses the GCL barrier blanket along the circumferential direction of the vertical inner wall of the treatment chamber, thereby achieving flexible pressing of the GCL barrier blanket, avoiding damage to the GCL barrier blanket, ensuring that the GCL barrier blanket is tightly attached to the vertical inner wall of the treatment chamber, so as to implement the 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 treatment chamber.

[0043] (2) The clamping frame of the present invention is lifted to the bottom of the processing chamber by means of a lifting mechanism, so that the anchor nails at the splicing position of the GCL barrier blanket penetrate the overlapping area of ​​the GCL barrier blanket, thereby achieving a tight bond of the GCL barrier blanket at the splicing position.

[0060] The following detailed description of exemplary embodiments of the invention is taken with reference to the accompanying drawings, which form part of the description and illustrate exemplary embodiments in which the invention may be practiced. While these exemplary embodiments have been described in sufficient detail to enable those skilled in the art to practice the invention, it should be understood that other embodiments may be implemented and various changes may be made to the invention without departing from the spirit and scope thereof. The more detailed description of embodiments of the invention below is not intended to limit the scope of the claimed invention, but is merely illustrative and not restrictive of the description of the features and characteristics of the invention, to suggest the best mode for carrying out the invention, and is sufficient to enable those skilled in the art to practice the invention. Therefore, the scope of the invention is defined only by the appended claims.

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

[0062] The following is in conjunction with the appendix Figures 1 to 9 The following is a detailed description of the vertical anti-seepage wall construction clamping frame for the pollutant treatment tank of the present invention:

[0063] Example

[0064] A type of clamping frame for the construction of a vertical seepage barrier wall for a pollutant treatment tank, such as Figure 1-5 As shown, it includes:

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

[0066] Circumferential pressing roller frame 300: connected to the vertical pressing roller frame 100, used to realize pressing in the circumferential position, 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 clamping frame to rotate.

[0069] The vertical pressing roller frame 200 is provided with multiple sets 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, with 4 to 6 rollers being preferred.

[0071] like Figure 3 and Figure 4 As shown, the vertical pressing roller frame 200 is equipped with a flattening flexible brush 211, which is located on the outer side of the vertical pressing roller 210. The flattening flexible brush 211 is strip-shaped and extends along the circumferential direction of the processing chamber 100. The flattening flexible brush 211 is made of rubber or other alternative deformable materials. Under normal conditions, it is a straight strip. When the first extension mechanism is activated, after the vertical pressing roller 210 abuts against the vertical inner wall of the processing chamber 100, the flattening flexible brush 211 abuts against the inner wall of the processing chamber 100. Then, the lifting mechanism 400 is activated, causing the flattening flexible brush 211 to rise and fall along the vertical inner wall of the processing chamber 100, flattening the GCL barrier blanket so that the GCL barrier blanket is tightly attached to the vertical inner wall of the processing chamber 100.

[0072] The flattening flexible brushes 211 have different lengths and 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 completely covered by the flattening flexible brushes 211, the projections of the flattening flexible brushes 211 in the vertical direction have overlapping areas.

[0073] In one embodiment, the flattening flexible brush 211 extends horizontally, and each set of flattening flexible brushes 211 is arranged at intervals in the vertical direction. The flattening flexible brushes 211 have overlapping portions in the vertical direction. As the first extension mechanism unfolds the vertical pressing roller 210, the flattening flexible brush 211 abuts against the vertical inner wall of the processing chamber 100, causing the flattening flexible brush 211 to deform and abut against the inner wall of the processing chamber 100. This ensures that the flattening flexible brush 211 is tightly attached to the inner wall of the processing chamber 100, thus ensuring the flattening effect of the GCL barrier blanket.

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

[0075] Specifically, to achieve 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, with multiple sets of the first extension arms 220 spaced apart along the circumferential direction of the processing chamber 100. The vertical pressing roller 210 is rotatably mounted on the lower end of the first extension arm 220, and the upper end of the first extension arm 220 is hinged to the first lifting frame 230. The first extension arm 220 is connected to a first drive unit, which drives the first extension arm 220 to rotate around the hinge axis.

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

[0077] The first drive screw 262 has a first driven gear 2621 at its upper end. The first driven gear 2621 cooperates with the first drive gear 2622. The first drive gear 2622 is connected to the first drive motor 2623. The first drive motor 2623 is mounted on the first lifting frame 230 to realize the expansion and contraction of the vertical pressing roller 210.

[0078] The first drive arm 240 is telescopically connected to the first drive disk 260 via the connecting arm 250, the vertical slide bar 251 and the 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 drive disk 260 to move down, the first drive arm 240 and the first extension arm 220 rotate around the hinge axis, so that the vertical pressing roller 210 is elastically and tightly attached to the GCL barrier blanket on the inner wall of the processing chamber 100. When encountering a flat position on the inner wall of the processing chamber 100, pressure damage to the inner wall of the processing chamber 100 is avoided.

[0079] The circumferential pressing roller frame 300 is provided with multiple sets of circumferential pressing rollers 310. The roller core of the circumferential pressing roller 310 has an angle with the horizontal plane and is arranged along the circumferential direction of the processing chamber 100.

[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 extension mechanism. The second driving unit is connected to the second extension mechanism and is used to drive the second extension mechanism. The circumferential pressing roller 310 is connected to the second extension mechanism, so that the circumferential pressing roller 310 is driven in the radial direction to achieve the circumferential pressing roller 310 approaching or moving away from the inner wall of the processing chamber 100.

[0081] Specifically, to enable the expansion or retraction of the circumferential pressing roller 320, the second extension mechanism includes a second extension arm 320. Multiple sets of the second extension arms 320 are spaced apart along the circumferential direction of the processing chamber 100. The circumferential pressing roller 310 is rotatably mounted on the lower end of the second extension arm 320, and the upper end of the second extension arm 320 is hinged to the second lifting frame 330. The second extension arm 320 is connected to a second drive unit, which 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. The roller frame 311 is slidably mounted on the connecting roller frame 313 via the slide rod 312. A spring 314 is sleeved on the slide rod 312. 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] The second unfolding mechanism allows the circumferential pressing roller 310 to abut against the vertical inner wall of the processing chamber 100. The compression spring 314 allows the circumferential pressing roller 310 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 adaptively abuts against the inner wall of the processing chamber 100. When there is a change in the verticality of the processing chamber 100, the roller body of the circumferential pressing roller 310 can always abut against the vertical inner wall of the processing chamber 100, ensuring the pressing effect on the GCL barrier blanket.

[0084] Furthermore, the second extension arm 320 is provided with two sets of limiting rods 321, which are arranged horizontally. The connecting roller frame 313 is located between the two sets of limiting rods 321, which can limit 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 drive unit includes a second drive arm 340. One end of the second drive arm 340 is hinged to the middle section of the second extension arm 320, and the other end of the second drive arm 340 is hinged to the second drive disk 350. A second drive nut 351 is provided at the center of the second drive disk 350. The second drive nut 351 cooperates with the second drive screw 352. The second drive screw 352 is coaxial with the first drive screw 262.

[0086] The second drive screw 352 has a second driven gear 3521 at its upper end. The second driven gear 3521 cooperates with the second drive gear 3522. The second drive gear 3522 is connected to the second drive motor 3523. The second drive motor 3523 is mounted on the first lifting frame 230.

[0087] To enable the vertical movement of the vertical pressing roller frame 200 and the circumferential pressing roller frame 300 within the processing chamber 100, the pressing frame is equipped with a lifting mechanism 400. The lifting mechanism 400 includes a lifting frame 410 located at the upper end of the processing chamber 100. The lifting frame 410 is equipped with a lifting unit, which includes a wheel 430 and a lifting cable 420 threaded through the wheel 430.

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

[0089] The use of multiple sets of pulleys 430 and lifting cables 420 ensures the stable lifting of the entire clamping frame and avoids tilting of the clamping frame. The lifting unit includes pulley blocks of existing technology, which can extend and retract the lifting cables 420 to lift or lower the lifting frame.

[0090] To achieve the rotation of the clamping frame, the lifting mechanism 400 is connected to the rotating mechanism. The rotating mechanism includes a rotating disk 510, and the hanging wheel 430 is fixed on the rotating disk 510. The rotating disk 510 is rotatably mounted on the lifting frame 410. The power motor and other equipment for lifting are mounted on the rotating disk 510. The lifting frame 410 is equipped with a stepper motor, which can slowly rotate the rotating disk 510 to ensure the rotation of the clamping frame and the slow rotation of the clamping frame.

[0091] To ensure a tight bond between the GCL barrier blankets within the treatment chamber 100, clamping strips 600 are provided at the joints of the GCL barrier blankets along the circumferential direction of the inner wall of the treatment chamber 100. Figure 8-9As shown, the clamping strip 600 is generally slotted and has a guide rail 620 at its extended end. The guide rail 620 is generally figure-eight shaped and has anchor pins 610. After the clamping frame is lowered to the lower end 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 slot of the clamping strip 600, so that the anchor pins 610 penetrate the overlapping area of ​​the GCL barrier blanket, achieving a tight bond between the GCL barrier blankets at the splicing point.

[0092] In actual construction, the treatment chamber 100 is mainly used to treat chemical pollutants. Its depth is 10 to 15 meters and its diameter is between 10 and 12 meters.

[0093] This application uses a lifting mechanism 400 to hoist the pressing frame to the bottom of the treatment chamber 100. First, by activating the first extension mechanism, the vertical pressing roller 210 abuts against the vertical inner wall of the treatment chamber 100. As the vertical pressing roller frame 200 moves up and down, it presses the splicing position of the GCL barrier blanket. By activating the second extension mechanism, the circumferential pressing roller 310 abuts against the vertical inner wall of the treatment chamber 100. By activating the rotation mechanism and the lifting mechanism 400, the circumferential pressing roller frame 300 moves up and down in a rotating manner. As the circumferential pressing roller frame 300 moves up and down, it presses the GCL barrier blanket along the circumferential direction of the vertical inner wall of the treatment chamber 100, ensuring that the GCL barrier blanket is tightly attached to the vertical inner wall of the treatment chamber 100, thereby sealing and bonding the joint position between the GCL barrier blankets and ensuring the reliability of the waterproofing construction of the entire vertical wall of the treatment chamber 100.

[0094] A method for constructing a vertical cut-off wall for a pollutant treatment tank, the method utilizing the aforementioned clamping frame for constructing the vertical cut-off wall for the pollutant treatment tank, comprising the following steps:

[0095] S101: Perform anti-seepage treatment on the bottom surface of the treatment chamber 100 by laying the GCL barrier blanket flat on the bottom surface of the treatment chamber 100.

[0096] S102: Release the GCL barrier blanket at one end of the roll from the top of the processing chamber 100 to the bottom position, apply overlap paste to the GCL barrier blanket to bond one end of the GCL barrier blanket to the GCL barrier blanket on the bottom surface of the processing chamber 100, apply overlap paste to the side of the GCL barrier blanket to bond the GCL barrier blankets together and to create an overlapping area between the GCL barrier blankets.

[0097] S103: Arrange the clamping strip 600 around the circumference of the processing chamber 100, and press the clamping strip 600 against the outside of the overlapping area of ​​the GCL barrier blanket.

[0098] S104: The lifting mechanism 400 is used to hoist the clamping frame to a position below the processing chamber 100. The first extension mechanism is activated so that the vertical pressing roller 210 is pressed on the outside of the clamping strip 600. The lifting mechanism 400 is activated so that the clamping frame rises and the anchor 610 on the clamping strip 600 penetrates the overlapping area of ​​the GCL barrier blanket.

[0099] like Figure 9 As shown, the inner wall of the processing chamber 100 is provided with a pressing strip 600. The pressing strip 600 is generally in the shape of a slot and the extended end is provided with a guide rail 620. The guide rail 620 is generally in the shape of an "eight". Anchor nails 610 are provided on the guide rail 620. After the pressing frame is lowered to the lower end 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 pressing frame, the vertical pressing roller 210 extends into the slot of the pressing strip 600, thereby squeezing one end of the anchor nail 610, so that the anchor nail 610 penetrates the overlapping area of ​​the GCL barrier blanket.

[0100] S105: Start the lifting mechanism 400 to hoist the clamping frame to a position below the processing chamber 100, start the second extension mechanism so that the circumferential pressing roller 310 presses against the inner wall of the processing chamber 100, start the rotation mechanism and the lifting mechanism 400 so that the circumferential pressing roller 310 moves 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.
