Description

Technical Field

[0001] This invention belongs to the field of geomembrane laying technology, and relates to a geomembrane laying device and laying method for solid hazardous waste landfills. Background Technology

[0002] Hazardous waste landfills are land-based disposal facilities for hazardous waste. They consist of several disposal units and structures, mainly including receiving and storage facilities, analysis and identification systems, pretreatment facilities, landfill disposal facilities, landfill closure and covering systems, leachate and wastewater treatment systems, environmental monitoring systems, emergency facilities, and other utilities and supporting facilities. The landfill disposal facilities also include anti-seepage systems and leachate collection and drainage systems.

[0003] The geomembrane within a landfill disposal unit is a core component of its anti-seepage system, playing a crucial role in controlling environmental pollution. Simply put, its core function is to form a low-permeability barrier, preventing leachate and landfill gases from contaminating the surrounding soil and groundwater.

[0004] Each treatment unit's structure has a protruding structure at the top of its walls, forming a horn-like structure. Figure 1 Two types of horn-shaped protrusions at the top of the wall are presented. The function of the protrusions is to provide stable support and positioning reference for the concrete closure cover after all solid hazardous waste backfilling is completed. This ensures that the closure structure can be tightly connected to the wall to form a complete and sealed system, ultimately achieving the safe closure of the solid hazardous waste landfill.

[0005] The presence of protruding structures at the top of the walls makes it difficult for the geomembrane to adhere properly when laid, affecting both laying efficiency and seepage prevention. Currently, manual assistance is used to ensure the geomembrane adheres to the protruding structures. However, since the walls range in height from 5m to 20m, this requires workers to operate on such high walls, raising safety concerns. Furthermore, manual laying is challenging due to varying skill levels among workers, making it difficult to guarantee the flatness and uniform tension of the geomembrane. At the horn-shaped protrusions, the geomembrane needs to be cut and spliced, and manual operation may lead to improper joint treatment, such as uneven welds, false welds, or missed welds, affecting the geomembrane's sealing performance and compromising construction quality.

[0006] Besides the horn-shaped protrusion, the upper part of rigid walls in structures can also be flat, or even concave, arc-shaped, or other irregular wall surfaces. Therefore, providing a geomembrane laying device and method that includes a horn-shaped protrusion and can be used for the upper part of structure walls to improve construction efficiency, ensure construction safety, and guarantee construction quality is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0007] To address the technical problem described in the background art of lacking a geomembrane laying device and method applicable to the upper surface of building walls, including a bull-horn-shaped protruding structure, which affects construction efficiency, construction safety, and construction quality, the present invention provides a geomembrane laying device and method for solid hazardous waste landfills.

[0012] Furthermore, it also includes a second transverse cylinder and a second clamping arm; the second clamping arm is symmetrically arranged on the other side of the vertical cylinder, and the structure of the second clamping arm is exactly the same as that of the first clamping arm. The second clamping arm includes two vertical second main connecting rods. Correspondingly, the second crossbar is also symmetrically arranged on the other side of the vertical cylinder, and the two second main connecting rods are respectively hinged to the second crossbar.

[0013] Furthermore, the first main connecting rod and the second main connecting rod are respectively fixedly connected to the clamping rod by fixing pins, and the angle between the first main connecting rod, the second main connecting rod and the clamping rod can be adjusted.

[0014] Furthermore, both the first and second transverse cylinders are single-piston double-acting cylinders, and the pneumatic control valve assembly includes two two-position five-way solenoid valves, which respectively control the first and second transverse cylinders.

[0015] Furthermore, both the first and second transverse cylinders are double-cylinder, double-acting, two-piston-rod cylinders; the pneumatic control valve assembly includes two two-position five-way solenoid valves, which respectively control the first and second transverse cylinders.

[0016] Furthermore, the vertical cylinder is a single-piston rod double-acting cylinder, and the piston rod of the vertical cylinder is connected to a connecting plate. The connecting plate is detachably connected to the upper surface of the structure wall. The rodless end of the vertical cylinder is connected to a support frame connector by bolts, and the support frame connector is fixedly connected to two longitudinal rods.

[0017] Furthermore, the connecting plate is fixedly connected to the upper surface of the structure wall by anchor bolts.

[0018] Furthermore, the connecting plate is fixedly connected to the upper surface of the structure wall via a walking clamping mechanism; the walking clamping mechanism includes a box and a box cover, and the box and the box cover, as well as the box cover and the connecting plate, are connected by ordinary screws; two walking shafts are evenly distributed in the front-back direction inside the box, and two walking wheels are installed on each walking shaft. Four through holes are provided on the bottom plate of the box, and the four walking wheels pass through the through holes to contact the upper surface of the structure wall; a third transverse cylinder is horizontally arranged between the two walking shafts, and a guide clamping wheel is installed at each end of the third transverse cylinder; the third transverse cylinder is fixed to the bottom plate of the box via a cylinder fixing seat.

[0019] In a preferred embodiment, the third transverse cylinder is a double-cylinder, double-acting, two-piston-rod cylinder, with a guide clamping wheel fixedly connected to each of the two piston rod ends.

[0020] As another preferred embodiment, the third transverse cylinder is a single-piston rod double-acting cylinder. A guide clamping wheel is fixedly connected to both the piston rod end and the rodless end of the third transverse cylinder. When the piston rod of the third transverse cylinder retracts and resets, the centers of the two guide clamping wheels coincide with the transverse geometric center of the housing.

[0021] Furthermore, the width of the box is 2 to 3 centimeters less than the width of the upper surface of the structure wall.

[0024] The present invention also provides a method for laying geomembrane in a solid hazardous waste landfill. This method utilizes a geomembrane laying device for solid hazardous waste landfills to lay the geomembrane, and includes the following steps:

[0025] Step 1: The geomembrane laying device for the solid hazardous waste landfill enters the designated work site and fixes the bottom connecting plate of the vertical cylinder to the upper surface of the structure wall. The piston rod of the vertical cylinder is in an extended state, and the geomembrane hangs down from the top of the wall.

[0026] Step 2: Adjust the piston rod extension of the first and second transverse cylinders so that the distance between the two first main connecting rods and the distance between the two second main connecting rods both exceed the width of the wall. At this time, the lower ends of the first and second clamping arms are in an open state.

[0027] Step 3: The piston rod of the vertical cylinder retracts, allowing the lower ends of the first and second clamping arms to descend to near the upper surface of the structure wall. The infrared marker is used to assist in positioning. The intelligent controller controls the vertical cylinder to continue retracting. Then, the piston rods of the first and second horizontal cylinders continue to extend until the two clamping rods clamp the geomembrane on both sides of the wall, so that the geomembrane adheres to the wall surface.

[0028] Step 4: Use a gas gun or nail gun to fix the geomembrane to the wall surface near the upper end of the structure wall. After completion, the piston rods of the first and second transverse cylinders retract, and the first and second clamping arms open to release the clamping.

[0029] Step 5: Control the piston rod of the vertical cylinder to extend, raise the support frame, and move the geomembrane laying device to the next work location.

[0030] Furthermore, step one also includes: calculating the required angle between the clamping rod and the main connecting rod based on the structural dimensions of the upper surface of the wall at the work site; if the required angle does not match the current angle, adjusting and fixing the angle. After adjusting the support frame to be basically horizontal in all directions using a level and pusher, the third transverse cylinder is activated by pressing the manual switch, causing the piston rod of the third transverse cylinder to retract. The two guide clamping wheels on both sides of the third transverse cylinder clamp the upper surface of the wall, thus fixing the bottom of the vertical cylinder.

[0031] Furthermore, step five also includes: extending the piston rod of the third transverse cylinder. At this time, the two guide clamping wheels guide and prevent the support frame from deviating and falling.

[0034] 2. The connecting plate at the bottom of the vertical cylinder is fixedly connected to the upper surface of the structure wall through the walking clamping mechanism, which facilitates the installation, dismantling and transfer of the geomembrane laying device.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0053] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0054] Example 1, please refer to Figures 2 to 13A geomembrane laying device for a solid hazardous waste landfill includes a support frame 2, a vertical cylinder 3, a first horizontal cylinder 4, a first clamping arm 5, and a clamping part 6; the support frame 2 includes two longitudinal rods 21, and a first horizontal rod 22 and a second horizontal rod 23 connecting the two longitudinal rods 21; one end of the vertical cylinder 3 is attached to the upper surface 1 of the structure wall (at... Figure 2 (Indicated by dashed lines) The vertical cylinder 3 is detachably connected, with the other end fixedly connected to the two longitudinal rods 21 via a support frame connector 31; the first clamping arm 5 includes two vertical first main connecting rods 51, which are symmetrically arranged on both sides of the first horizontal rod 22 and hinged to the first horizontal rod 22 respectively; the two ends of the first transverse cylinder 4 are fixedly connected to the upper ends of the two first main connecting rods 51 respectively; the clamping part 6 includes two longitudinally extending clamping rods 61, which are fixedly connected to the lower ends of the two first main connecting rods 51 respectively; it also includes a pneumatic control valve assembly 7, which is connected to the vertical cylinder 3 and the first transverse cylinder 4 via an air duct (not shown in the figure), and controls the extension and retraction of the piston rods of the vertical cylinder 3 and the first transverse cylinder 4. In embodiment 1, the first horizontal rod 22 and the second horizontal rod 23 are welded and fixed to the two longitudinal rods 21 respectively.

[0055] Please refer to Figure 2 as well as Figures 5 to 8 Each first main connecting rod 51 is connected to its hinged first horizontal rod 22 via a clamping arm connector 52. The clamping arm connector 52 is U-shaped, with its middle section passing through the first main connecting rod 51. Both ends of the clamping arm connector 52 are welded and fixed to the two sides of the end of the first horizontal rod 22. Through the clamping arm connector 52, the first main connecting rod 51, pushed by the first horizontal cylinder 4, reciprocates around the first horizontal rod 22, causing the clamping rod 61, fixedly connected to the first main connecting rod 51, to reciprocate, thus achieving the clamping or opening state of the clamping part 6. When the piston rod of the first horizontal cylinder 4 retracts, the first clamping arm 5 and the lower clamping part 6 are in an open state; when the piston rod of the first horizontal cylinder 4 extends, the first clamping arm 5 and the lower clamping part 6 are in a clamped state. In embodiment 1, the upper surface 1 of the structure wall is a horn-shaped protruding structure 17 (in... Figure 2 (Represented by a dashed line in the middle), in the clamped state, the clamping part 6 is in close contact with the junction of the protruding structure 17 and the vertical plane of the wall.

[0056] Please refer to Figure 5 , Figure 9Two longitudinal rods 21 are arranged in parallel, and two clamping rods 61 are parallel to the two longitudinal rods 21. The vertical cylinder 3 is set at the center of mass of the support frame 2, and the connection between the vertical cylinder 3 and the upper end face 1 of the structure wall is the longitudinal centerline of the upper end face 1 of the structure wall. The setting position of the vertical cylinder 3 can ensure the balance and stability of the support frame 2, and also ensure that the first clamping arm 5 and the clamping part 6 are symmetrically arranged on both sides of the upper end face 1 of the structure wall, which facilitates clamping on both sides of the upper end face 1 of the structure wall, so that the geomembrane is in contact with the surface of the protruding structure 17.

[0057] Please refer to Figure 5 , Figure 6 ,as well as Figure 7 Embodiment 1 of the present invention further includes a second transverse cylinder 8 and a second clamping arm 9; the second clamping arm 9 is symmetrically arranged on the other side of the vertical cylinder 3, and the structure of the second clamping arm 9 is exactly the same as that of the first clamping arm 5. The second clamping arm 9 includes two vertical second main connecting rods 91. Correspondingly, the second crossbar 23 is also symmetrically arranged on the other side of the vertical cylinder 3, and the two second main connecting rods 91 of the second clamping arm 9 are respectively hinged to the second crossbar 23. The two ends of the second transverse cylinder 8 are respectively fixedly connected to the upper ends of the two second main connecting rods 91 of the second clamping arm 9, and the lower ends of the two second main connecting rods 91 of the second clamping arm 9 are respectively fixedly connected to the clamping rod 61 on the same side; the second transverse cylinder 8 is of the same model as the first transverse cylinder 4, and the piston rod movement is synchronized. The second transverse cylinder 8 and the second clamping arm 9 are conducive to the overall structural balance of the support frame 2, so that the clamping force of the clamping part 6 on both sides of the upper end face 1 of the structure wall is evenly distributed, so that the geomembrane is subjected to uniform force, thereby ensuring the bonding quality between the geomembrane and the surface of the protruding structure 17.

[0058] The first main connecting rod 51 and the second main connecting rod 91 are fixedly connected to the clamping rod 61 by fixing pins 18. The angle between the first main connecting rod 51, the second main connecting rod 91 and the clamping rod 61 can be adjusted. The angle can be adjusted before construction according to the size of the protruding structure of the wall of the building at different work locations. Those skilled in the art can select a suitable adjustment structure according to the angle adjustment needs. This is a relatively mature technology in this field, and the specific structural form will not be described in detail.

[0059] In this embodiment 1, both the first transverse cylinder 4 and the second transverse cylinder 8 are single-piston double-acting cylinders. The pneumatic control valve assembly 7 includes two two-position five-way solenoid valves, which control the first transverse cylinder 4 and the second transverse cylinder 8 respectively.

[0060] In other preferred embodiments, the first transverse cylinder 4 and the second transverse cylinder 8 can also be double-cylinder double-acting two-piston rod cylinders; in this case, the pneumatic control valve assembly 7 still includes two two-position five-way solenoid valves, which control the first transverse cylinder 4 and the second transverse cylinder 8 respectively.

[0061] The vertical cylinder 3 is a single-piston rod double-acting cylinder. The piston rod of the vertical cylinder 3 is connected to a connecting plate 32, which is detachably connected to the upper surface 1 of the structure wall. The rodless end of the vertical cylinder 3 is connected to the support frame connector 31 by bolts, and the support frame connector 31 is fixedly connected to the two longitudinal rods 21.

[0062] Please refer to Figure 5 , Figures 9 to 13 The connecting plate 32 can be fixedly connected to the upper end face 1 of the structure wall by anchor bolts. However, in this embodiment 1, the connecting plate 32 is fixedly connected to the upper end face 1 of the structure wall by a walking clamping mechanism 10. The walking clamping mechanism 10 includes a box 101 and a box cover 102. The box 101 and the box cover 102, as well as the box cover 102 and the connecting plate 32, are connected by ordinary screws. Two walking shafts 103 are evenly distributed in the front and back direction inside the box 101. Two walking wheels 104 are installed on each walking shaft 103. Four through holes 109 are provided on the bottom plate of the box 101. The four walking wheels 104 pass through the through holes 109 and contact the upper end face 1 of the structure wall. A third transverse cylinder 105 is horizontally arranged between the two walking shafts 103. A guide clamping wheel 106 is installed at each end of the third transverse cylinder 105. The third transverse cylinder 105 is fixed to the bottom plate of the box 101 by a cylinder fixing seat 108.

[0063] Please refer to Figure 11 The third transverse cylinder 105 is a double-cylinder, double-acting, two-piston rod cylinder. A guide clamping wheel 106 is fixedly connected to each of the two piston rod ends of the third transverse cylinder 105. The third transverse cylinder 105 adopts a double-cylinder, double-acting, two-piston rod cylinder, so that the two guide clamping wheels 106 retract or extend at the same time, which facilitates the walking clamping mechanism 10 to quickly complete the switching between clamping or walking working states.

[0064] Please refer to Figure 12 as well as Figure 13 Example 1 also illustrates the case where the third transverse cylinder 105 is a single-piston rod double-acting cylinder. A guide clamping wheel 106 is fixedly connected to both the piston rod end and the rodless end of the third transverse cylinder 105. When the piston rod of the third transverse cylinder 105 retracts and resets, the centers of the two guide clamping wheels 106 coincide with the transverse geometric center of the housing 101.

[0065] The width of the box 101 is 2 to 3 centimeters smaller than the width of the upper end face 1 of the structure wall. This ensures that the two guide clamping wheels 106 can clamp the upper end face 1 of the structure wall, and also helps to prevent the support frame 2 from deviating and falling.

[0066] Please refer to Figure 2 , Figure 3 and Figure 10 Four threaded holes are provided on the cover 102 opposite to the longitudinal rod 21. A guide rod 107 is installed in each threaded hole, and the guide rod 107 passes through the longitudinal rod 21 above the threaded hole. The guide rod 107 can make the center line of symmetry of the support frame 2 coincide with the center line of symmetry of the cover 102 on the traveling clamping mechanism 10, thereby ensuring that the relative positions of the support frame 2 and the traveling clamping mechanism 10 are fixed in both the front-back and left-right directions and will not change due to the lifting and lowering of the support frame 2. This is beneficial for determining the working position of the clamping arm and the clamping part, and allows the support frame 2 to lift and lower smoothly. When it is necessary to push and level the equipment, the thrust can be transmitted to the traveling clamping mechanism 10 through the guide rod 107, instead of just through the vertical cylinder 3.

[0067] Please refer to Figure 2 and Figure 4 In this embodiment, an intelligent controller 11 is also included. The intelligent controller 11 is electrically connected to the pneumatic control valve assembly 7. The intelligent controller 11 and the pneumatic control valve assembly 7 are mounted on the support frame 2. The intelligent controller 11 and the pneumatic control valve assembly 7 can be placed on two vertical rods 21. In this embodiment, a third horizontal rod 24 is also provided. The third horizontal rod 24 is located near the end of the two vertical rods 21 and is connected to the two vertical rods 21. The intelligent controller 11 and the pneumatic control valve assembly 7 are placed on the third horizontal rod 24.

[0068] Please refer to Figure 2 An infrared line marker 12 and an infrared receiver 13 are provided on the clamping rod 61, and the infrared line marker 12 and the infrared receiver 13 are electrically connected to the intelligent controller 11. At the ends of the two vertical rods 21, push handles 14 are provided, and a level 15 and a manual switch 16 are installed on the push handles 14. The manual switch 16 is electrically connected to the intelligent controller 11.

[0069] Embodiment 1 of the present invention also provides a method for laying geomembrane in a solid hazardous waste landfill. This method uses a geomembrane laying device for solid hazardous waste landfills to lay the geomembrane, and includes the following steps in sequence:

[0070] Step 1: Enter the designated work site and fix the bottom connecting plate 32 of the vertical cylinder 3 to the upper end face 1 of the structure wall. The piston rod of the vertical cylinder 3 is in an extended state, and the geomembrane hangs down from the top of the wall.

[0071] Step 2: Adjust the piston rod extension of the first transverse cylinder 4 and the second transverse cylinder 8 so that the distance between the two first main connecting rods 51 and the distance between the two second main connecting rods 91 both exceed the width of the wall. At this time, the lower ends of the first clamping arm 5 and the second clamping arm 9 are in an open state.

[0072] Step 3: The piston rod of the vertical cylinder 3 retracts, allowing the lower ends of the first clamping arm 5 and the second clamping arm 9 to descend to near the upper surface 1 of the structure wall. The infrared marker 12 is used to assist in positioning. The intelligent controller 11 controls the vertical cylinder 3 to continue retracting. Then, the piston rods of the first horizontal cylinder 4 and the second horizontal cylinder 8 continue to extend until the two clamping rods 61 clamp the geomembrane on both sides of the wall, so that the geomembrane is in contact with the surface of the protruding structure 17.

[0073] Step 4: Use a gas gun or nail gun to fix the geomembrane in the area of ​​the protruding structure 17. After completion, the piston rods of the first transverse cylinder 4 and the second transverse cylinder 8 retract, and the first clamping arm 5 and the second clamping arm 9 open to release the clamping.

[0074] Step 5: Control the piston rod of the vertical cylinder 3 to extend, raise the support frame 2, and move the geomembrane laying device to the next work location.

[0075] Step one also includes: calculating the required angle between the clamping rod 61 and the main connecting rod based on the dimensions of the protruding structure 17 of the building wall at the work site; if the required angle does not match the current angle, adjusting and fixing the angle. After adjusting the support frame 2 to be basically horizontal in all directions using the level 15 and pusher 14, the third horizontal cylinder 105 is activated by pressing the manual switch 16, causing the piston rod of the third horizontal cylinder 105 to retract. The two guide clamping wheels 106 on both sides of the third horizontal cylinder 105 clamp the two sides of the upper end face 1 of the building wall, thus fixing the bottom of the vertical cylinder 3.

[0076] Step five also includes: extending the piston rod of the third transverse cylinder 105. At this time, the two guide clamping wheels 106 guide and prevent the support frame from deviating and falling, pushing the pusher 14, and using the traveling wheels 104 at the bottom of the box, pushing the geomembrane laying device along the upper end face 1 of the structure wall to the next working location. When the geomembrane laying device passes the intersection of the upper end faces 1 of the two structure walls, the extension of the piston rod of the vertical cylinder 3 should be such that the bottom of the clamping part 6 is higher than the upper end face 1 of the structure wall when the first clamping arm 5 and the second clamping arm 9 are in their maximum open state, so that the geomembrane laying device can smoothly pass through the intersection of the upper end faces 1 of the two structure walls.

[0077] The geomembrane laying device of Embodiment 1 of this invention enables the impermeable geomembrane on both sides of the entire wall to be tightly adhered to the protruding structure 17 at the upper end of the wall, greatly improving the geomembrane laying efficiency while ensuring the impermeability effect after laying. The connecting plate 32 at the bottom of the vertical cylinder 3 is fixedly connected to the upper end face 1 of the structure wall through the walking clamping mechanism 10, facilitating the installation, dismantling, and transfer of the geomembrane laying device. The working status of the geomembrane laying device is controlled by the intelligent controller 11, which greatly reduces the workload of construction personnel on the upper end face 1 of the structure wall and improves construction safety. The geomembrane laying device of this embodiment has a simple and practical structure, low installation and use costs, convenient operation, and complete functions. It can adapt to the laying of geomembranes on the horn-shaped protruding structures 17 on the walls of solid hazardous waste landfills of different specifications, has strong versatility, and is easy to promote and apply.
