[0002] Geomembrane is a geosynthetic material made of plastic film as the impermeable base material and non-woven fabric. It is a waterproof building material that is impermeable and moisture-proof. It has excellent resistance to environmental stress cracking and excellent resistance to chemical corrosion. It is used in landfills, tailings storage sites, canal seepage prevention, dam seepage prevention and subway projects, etc.

[0003] Currently, during the flattening process of geomembranes, due to the relatively hard surface of the geomembrane, air pockets are prone to occur. Therefore, the geomembrane needs to be processed to ensure it adheres to the ground. Because the geomembrane is relatively thin and light, a protective layer of backfill material is required to prevent it from being blown away by the wind. This flattening process requires a large amount of manpower, and the flatness is not high and the flattening speed is slow, sometimes making it difficult to meet the needs of rapid flattening in engineering projects.

[0021] The above technical solution utilizes the lower surface of the baffle roller to contact the ground and the upper surface to be close to the lower surface of the flat-pressure trolley, thereby preventing impurities blown by the cleaning nozzle from splashing backward.

[0022] A flattening method for a planar hand-push type automatic geomembrane flattening device, the flattening method being as follows:

[0023] Step 1: Install and fix the geomembrane roll using the rotating shaft, and stretch the geomembrane roll into a trapezoidal shape using the stretching roller. Finally, extend the geomembrane roll through the outlet to the bottom of the flat pressing trolley and fill the storage cylinder with the flat pressing layer. Start the blower, and the blower blows and sweeps away the impurities and dust on the ground through the cleaning nozzle. Push the flat pressing trolley, and the flat pressing trolley pushes large impurities to both sides through the push plate.

[0024] Step 2: Fix one end of the geomembrane to the ground, start the drive motor, and the drive motor drives the rotating shaft to rotate through the first transmission mechanism. The geomembrane extends and passes through the surfaces of three extension rollers in sequence, rubbing against each of the extension rollers. The drive motor drives the limiting shaft and limiting plate to rotate through the second transmission mechanism. The flat pressing layer in the storage cylinder falls into the feeding hopper and enters. The limiting plate separates the flat pressing layer in the feeding hopper. When the limiting shaft rotates, the limiting plate pushes the separated flat pressing layer to the lower end of the feeding hopper. The flat pressing layer at the lower end of the feeding hopper covers the surface of the laid geomembrane. The flat pressing roller is pushed by the flat pressing trolley to squeeze the surface of the geomembrane.

[0025] Step 3: Solar heat energy is transferred to the surface of the geomembrane through the light-transmitting plate. The geomembrane is heated and becomes more flexible. The geomembrane drives the stretching roller to rotate through friction. The stretching roller drives the rotating disk to rotate through the third transmission mechanism. The rotating disk drives the fixed block to rotate around the axis of the rotating disk. When the rotating block and the fixed block rotate, the tie rod limits the rotating block. The rotating block and the fixed block rotate relative to each other. The rotating block drives the tie rod to deflect. Under the limitation of the slider and the fixed rod, the tie rod reciprocates on the surface of the limiting rod. At the same time, the upper end of the tie rod reciprocates laterally on the surface of the connecting plate. Under the pull of the slider, the tie rod reciprocates vertically. The upper end of the tie rod pushes the connecting plate through the limiting ring. The connecting plate drives one end of the light-transmitting plate to reciprocate. After the light-transmitting plate deflects, the impurities adhering to the surface are shaken off.

[0026] The beneficial effects of this invention are as follows:

[0027] 1. By installing a heating mechanism at the top of the flatbed trolley, the interior of the flatbed trolley is sealed by a light-transmitting plate in the heating mechanism. This reduces the airflow inside the flatbed trolley while the geomembrane, stretched by the stretching roller, absorbs the solar radiation heat energy, making the geomembrane softer and easier to bend, unfold, and flatten. Appropriate heating can improve the extensibility and plasticity of the geomembrane, helping to solve the difficulties encountered when laying geomembranes in low-temperature environments or hard soils. The heated geomembrane is also more adaptable to changes in terrain and curved shapes.

[0028] 2. By installing a geomembrane-laying mechanism inside the flatbed trolley, the geomembrane roll is installed using the rotating shaft in the geomembrane-laying mechanism. At the same time, the geomembrane roll is rotated by the drive motor, causing the geomembrane roll to extend. Simultaneously, the limiting shaft in the storage cylinder is rotated, thereby controlling the material discharge in the hopper. This makes the geomembrane-laying mechanism convenient for extending the geomembrane and simultaneously conveying the flatbed layer.

[0029] 3. By installing a sweeping mechanism inside the flatbed trolley, the blower in the sweeping mechanism blows air to sweep the ground while the motor end of the blower is close to the geomembrane. This allows the heat generated by the blower to be transferred to the surface of the geomembrane, thus providing auxiliary heating to the geomembrane. At the same time, the geomembrane facilitates the removal of heat from the flatbed trolley, preventing the blower from overheating. Attached Figure Description

A large quantity of the flattened layer is stored in the storage cylinder 25, facilitating its transport. A limiting cylinder 28 is fixedly inserted into the middle side wall of the discharge hopper 26. The limiting cylinder 28 and the discharge hopper 26 are integrally formed. The inner wall of the limiting cylinder 28 is rotatably connected to a limiting shaft 29 via bearings. A limiting plate 210 is fixedly connected to the outer surface of the limiting shaft 29.

A flat roller 212 is installed on the lower surface of the flat roller trolley 1. The flat roller 212 is located between the discharge port 27 and the membrane discharge port 24. The flat roller 212 is used to press and flatten the geomembrane, so as to facilitate the flat layer to cover the surface of the geomembrane.

[0041] By installing a geomembrane-laying mechanism inside the flat-press trolley 1, the geomembrane roll 2 is installed using the rotating shaft 22 in the geomembrane-laying mechanism. At the same time, the geomembrane roll 2 is rotated by the drive motor 23, causing the geomembrane roll 2 to extend. Simultaneously, the limiting shaft 29 in the storage cylinder 25 is rotated, thereby controlling the material discharge in the discharge hopper 26. This makes the geomembrane-laying mechanism convenient for extending the geomembrane and for synchronously conveying the flat-press layer.

[0042] To heat the geomembrane, mounting bases 31 are fixedly connected to the upper surface of the flatbed trolley 1. The opposing surfaces of adjacent mounting bases 31 are rotatably connected to a light-transmitting plate 3 via a rotating shaft. Nylon cloth 32 is fixedly connected to the lower surfaces of both ends of the light-transmitting plate 3. The lower ends of the nylon cloth 32 are fixedly connected to the upper inner wall of the flatbed trolley 1. An extension roller 33 is rotatably connected to the inner wall of the flatbed trolley 1 via a rotating shaft. The three extension rollers 33, combined with the geomembrane roll 2, form a trapezoidal shape. The geomembrane in the geomembrane roll 2 is stretched by the extension rollers 33. The extension rollers 33 pre-stretch the geomembrane within the flatbed trolley 1, thereby increasing the surface area of ​​the geomembrane exposed to heat. A third transmission mechanism 34 is driven to the rotating shaft surface of an extension roller 33. The other end of the third transmission mechanism 34 is rotatably connected to a rotating disk 35 via a rotating shaft.

A sliding connection is used, utilizing the transmission connection between the third transmission mechanism 34 and the extension roller 33 connected to its own surface. The outer shell 315 inside the third transmission mechanism 34 is fixedly connected to the inner wall of the flat pressing cart 1 through the rotating shaft on the surface of the extension roller 33, thereby facilitating the installation and fixation of the third transmission mechanism 34. A connecting plate 311 is fixedly connected to the lower surface edge of the light-transmitting plate 3. A sliding groove is opened on the upper surface of the connecting plate 311. The surface of the connecting plate 311 is slidably sleeved with the upper end of the pull rod 38 through the sliding groove. A limit ring 312 is fixedly sleeved on the upper end surface of the pull rod 38. Two limit rings 312 on the same pull rod 38 surface are located at both ends of the connecting plate 311. The first transmission mechanism 21, the second transmission mechanism 211, and the third transmission mechanism 34 are all composed of transmission wheels 313, transmission belts 314, and housings 315. Two adjacent transmission wheels 313 are located at the two ends of the housing 315, and the transmission wheels 313 are rotatably connected to the inner wall of the housing 315. The two transmission wheels 313 inside the housing 315 are connected by transmission belts 314. By installing two limiting rings 312 at the upper end of the same pull rod 38, it is convenient to pull down or push up the connecting plate 311. Two limiting rings 312 can also be installed at the lower end of the pull rod 38 to facilitate the transmission between the lower end of the pull rod 38 and the rotating block 37.

[0043] By installing a heating mechanism at the top of the flatbed trolley 1, the interior of the flatbed trolley 1 is sealed by the light-transmitting plate 3 in the heating mechanism. This reduces the airflow inside the flatbed trolley 1 while the geomembrane, stretched by the stretching roller 33, absorbs the solar radiation heat energy, making the geomembrane softer and easier to bend, unfold, and flatten. Appropriate heating can improve the extensibility and plasticity of the geomembrane, helping to solve the difficulties encountered when laying geomembranes in low-temperature environments or hard soil. The heated geomembrane is also more adaptable to changes in terrain and curved shapes.

[0044] To clean the ground, the surface of the blower 4 is fixedly connected to the inner wall of the flatbed trolley 1. The blower 4 is located below the stretching roller 33. An air inlet slot is provided on the front surface of the flatbed trolley 1, which communicates with the air inlet of the blower 4. A connecting hose 41 is installed at the air outlet of the blower 4. A cleaning nozzle 42 is fixedly connected to the lower surface of the flatbed trolley 1. The cleaning nozzle 42 is located in front of the film outlet 24. Two adjacent cleaning nozzles 42 are combined in a V-shape. By using the V-shape combination of two cleaning nozzles 42, thus... To facilitate blowing impurities and dust to both sides of the flat-pressure trolley 1, the upper end of the cleaning nozzle 42 is fixedly connected to and communicates with the lower end of the connecting hose 41. A push plate 43 is fixedly connected to the lower surface of the flat-pressure trolley 1. The push plate 43 is located in front of the cleaning nozzle 42. A baffle roller 44 is installed on the lower surface of the flat-pressure trolley 1. The baffle roller 44 is located between the cleaning nozzle 42 and the film outlet 24. By using the lower surface of the baffle roller 44 to contact the ground and the upper surface to be close to the lower surface of the flat-pressure trolley 1, the impurities blown by the cleaning nozzle 42 are prevented from splashing backward.

[0045] By installing a cleaning mechanism inside the flatbed trolley 1, the blower 4 in the cleaning mechanism blows air to clean the ground while the motor end of the blower 4 is brought close to the geomembrane. This allows the heat generated by the blower 4 during operation to be transferred to the surface of the geomembrane, thereby providing auxiliary heating to the geomembrane. At the same time, it facilitates the removal of heat from the flatbed trolley 1 through the geomembrane, preventing the blower 4 from overheating.

[0046] The method of flattening is as follows:

[0047] Step 1: Install and fix the geomembrane roll 2 through the rotating shaft 22, and stretch the geomembrane roll 2 into a trapezoidal shape through the stretching roller 33. Finally, extend it through the membrane outlet 24 to the bottom of the flat pressing trolley 1 and fill the flat pressing layer into the storage cylinder 25. Start the blower 4. The blower 4 blows and sweeps the impurities and dust on the ground through the cleaning nozzle 42. Push the flat pressing trolley 1. The flat pressing trolley 1 pushes the large impurities to both sides through the push plate 43.

[0048] Step 2: Fix one end of the geomembrane to the ground, start the drive motor 23, drive the rotating shaft 22 to rotate through the first transmission mechanism 21, the geomembrane extends and passes through the surfaces of the three extension rollers 33 in sequence and rubs against each extension roller 33, drive the limiting shaft 29 and limiting plate 210 to rotate through the second transmission mechanism 211, the flat pressing layer in the storage cylinder 25 falls into the hopper 26, the limiting plate 210 separates the flat pressing layer in the hopper 26, and when the limiting shaft 29 rotates, the limiting plate 210 pushes the separated flat pressing layer to the lower end of the hopper 26, the flat pressing layer at the lower end of the hopper 26 covers the surface of the laid geomembrane, the flat pressing roller 212 squeezes the surface of the geomembrane under the push of the flat pressing trolley 1;

[0049] Step 3: Solar heat energy is transferred to the surface of the geomembrane through the light-transmitting plate 3. The geomembrane is heated, becoming more flexible. Friction causes the stretching roller 33 to rotate. The stretching roller 33, through the third transmission mechanism 34, drives the rotating disk 35 to rotate. The rotating disk 35 causes the fixed block 36 to rotate around its axis. As the rotating block 37 rotates with the fixed block 36, the pull rod 38 limits its movement. The rotating block 37 rotates relative to the fixed block 36. The pull rod 38 is deflected. Under the limitation of the slider 39 and the fixed rod 310, the pull rod 38 reciprocates on the surface of the limiting rod. While the upper end of the pull rod 38 reciprocates laterally on the surface of the connecting plate 311, the pull rod 38 reciprocates vertically under the pull of the slider 39. The upper end of the pull rod 38 pushes the connecting plate 311 through the limiting ring 312. The connecting plate 311 drives one end of the light-transmitting plate 3 to reciprocate and deflect. After the light-transmitting plate 3 deflects, the impurities adhering to the surface are shaken off.
