[0016] According to another aspect of the present invention, a method for laying a geomembrane is provided, wherein the geomembrane is laid on the working surface to be laid using the above-described geomembrane laying system, and the geomembrane laying method includes the following steps: Step S1: Lay a transport track above the work surface to be paved, and set up a gantry loading vehicle at one end of the transport track to hoist the construction paving vehicle and the material delivery vehicle onto the transport track. Step S2: The gantry loading trolley hoists the material onto the feeding trolley, which then moves along the transport track to the construction paving trolley and transfers the material onto it. Step S3: The construction paving vehicle moves along the transport track, and during the movement, it evenly spreads fine granular material on the work surface to be paved, thus completing the support layer paving of one work surface; Step S4: Place the geomembrane roll on the construction laying vehicle and fix the starting end of the geomembrane in the support layer; move the construction laying vehicle along the transport track and lay the geomembrane on top of the support layer during the movement to complete the geomembrane laying of one working surface.

[0017] Furthermore, after the support layer, geomembrane, and protective layer of one working surface are laid, a portion of the transport track is disconnected. The disconnected transport track is moved to the top of the next working surface to be laid using the track dismantling and assembly hanger and electric hoist of the low-level feeding and track dismantling and assembly vehicle. This process is repeated to move multiple disconnected transport track segments to the top of the next working surface to be laid. The multiple disconnected transport track segments are then connected to form a complete transport track. Steps S2 to S5 are repeated to lay the geomembrane for the next working surface to be laid.

[0018] Compared with the prior art, the present invention has the following beneficial effects: (1) The geomembrane laying system of the present invention can effectively reduce manual labor input and reduce construction costs. Under the same time and workload, the original manual laying requires about 40 people, while the geomembrane laying system of the present invention only requires 8 people to complete the laying work. In addition, the power consumption of the equipment is not large, and with the wear and tear of the equipment, it can save about 40% of the original manual laying cost.

[0019] (2) The geomembrane laying system of the present invention also greatly improves the laying quality. All construction workers do not work on the laid geomembrane, which effectively reduces human damage to the geomembrane. The laying of materials is done by mechanical equipment, which reduces collisions between materials.

[0020] (3) The geomembrane laying system of the present invention has a strong standardization of laying results. Before the equipment is constructed, experiments can be conducted to adjust the equipment parameters so that the laying meets the engineering design requirements before full laying is carried out. The laying standard is uniform, which reduces the factors of differences in laying effect caused by differences in construction personnel in manual laying. Attached Figure Description

[0046] See Figures 1 to 22 This invention discloses a geomembrane laying system, which is mainly used for laying geomembrane, a supporting layer below the geomembrane, and a protective layer above the geomembrane. As shown in the figure, the geomembrane laying system mainly includes a transport track 1, a gantry loading vehicle 2, a construction laying vehicle 3, and a material delivery vehicle 4. The transport track 1 is erected above the working surface 100 to be paved; the transport track 1 is a double track, which can allow two vehicles to pass through the track at the same time; the gantry loading vehicle 2 is set at one end of the transport track 1; the construction paving vehicle 3 is slidably set on the transport track 1, and the construction paving vehicle 3 is used to lay the material to be paved (such as sand, gravel, precast concrete blocks) and geomembrane on the working surface 100 to be paved, thereby forming a support layer, geomembrane and protective layer on the working surface 100 to be paved; the feeding vehicle 4 is slidably set on the transport track 1, and the feeding vehicle 4 is used to transport the material to be paved from the gantry loading vehicle 2 to the construction paving vehicle 3.

[0047] The aforementioned geomembrane laying system utilizes a transport track 1, with a gantry loading trolley 2 at one end. A construction laying trolley 3 and a material delivery trolley 4 slide along the transport track 1. The gantry loading trolley 2 lifts the material to be laid from the material transport vehicle onto the material delivery trolley 4. The material delivery trolley 4 moves along the transport track 1 to the vicinity of the construction laying trolley 3 and transfers the material from the material delivery trolley 4 onto the construction laying trolley 3. The construction laying trolley 3 then sequentially lays the support layer, geomembrane, and protective layer on the work surface 100. Compared to existing manual geomembrane laying methods, this invention's geomembrane laying system significantly reduces labor input, lowers construction costs, improves laying quality, and shortens the construction cycle.

[0048] Specifically, see Figures 4 to 8 In this embodiment, the construction paving vehicle 3 mainly includes a construction paving vehicle chassis 31, a fine granular material feeding auger 32, a fine granular material trough 33, and a rotary spreader 34. The construction paving vehicle chassis 31 is slidably mounted on the transport track 1. A geomembrane roll installation station 311 is provided on one side of the chassis 31 for placing the geomembrane roll, which is used to lay the geomembrane as the construction paving vehicle 3 moves. The fine granular material feeding auger 32 is mounted on the construction paving vehicle chassis 31, and its discharge end extends from one side of the chassis 31. The granular material trough 33 is installed on the underframe 31 of the construction paving vehicle. The fine granular material trough 33 is used to receive the material (such as sand and gravel) conveyed by the feeding vehicle 4 and deliver the material to the feed end of the fine granular material feeding screw 32. The rotary spreader 34 is installed below the discharge end of the fine granular material feeding screw 32 and is connected to the discharge end of the fine granular material feeding screw 32. It is used to spread the fine granular material in the fine granular material feeding screw 32 onto the working surface 100 to be paved.

[0049] During the construction of the support layer, the feeding vehicle 4 delivers fine granular materials (such as sand and gravel) into the fine granular material trough 33, which then delivers the fine granular materials into the feed end of the fine granular material feeding screw 32. The fine granular materials are then transported by the fine granular material feeding screw 32 to the discharge end located on one side of the construction paving vehicle chassis 31. The fine granular materials fall from the discharge end into the rotary spreader 34. As the construction paving vehicle 3 moves along the transport track 1, the rotary spreader 34 evenly spreads the fine granular materials on the working surface 100 to be paved, forming a support layer on the working surface 100.

[0050] After the support layer is laid, the geomembrane roll is placed on the geomembrane roll installation station 311 on the underframe 31 of the construction laying vehicle, and the starting end of the geomembrane is fixed in the support layer; as the construction laying vehicle 3 moves along the transport track 1, a geomembrane is laid on top of the support layer to form a layer.

[0051] See Figures 4 to 8In this embodiment, the construction paving vehicle 3 further includes a block material laying truss 35, a mobile pallet pushing and pulling mechanism 36, a block material laying mechanism 37, and a mobile pallet hanger 38. The block material laying truss 35 is mounted on the construction paving vehicle chassis 31; the mobile pallet pushing and pulling mechanism 36 is mounted on the block material laying truss 35 and is used to pull the mobile pallet 110 containing block materials (such as precast concrete blocks) from the material delivery vehicle 4 onto the construction paving vehicle 3; the block material laying mechanism 37 is mounted above the block material laying truss 35 and is used to lay the block materials in the mobile pallet 110 onto the work surface 100 to be laid; the mobile pallet hanger 38 is mounted above the mobile pallet pushing and pulling mechanism 36 and is used to lift the empty mobile pallet 110 back from the construction paving vehicle 3 to the material delivery vehicle 4.

[0052] After the geomembrane is laid, fine-grained materials (crushed stone and sand) are laid on top of the geomembrane, and then precast concrete blocks are laid. During the laying of precast concrete blocks, the mobile pallet 110 on the material delivery vehicle 4, which is loaded with block materials (precast concrete blocks), is pulled onto the block material laying truss 35 by the mobile pallet push-pull mechanism 36 on the construction laying vehicle 3. As the construction laying vehicle 3 moves with the transport track 1, the block material laying mechanism 37 picks up the block material from the mobile pallet 110 and lays it on the geomembrane, forming a protective layer on top of the geomembrane. The empty mobile pallet 110 is lifted back from the construction laying vehicle 3 to the material delivery vehicle 4 by the mobile pallet hanger 38.

[0053] In this embodiment, the movable pallet push-pull mechanism 36 includes a push-pull drive motor 361, two push-pull screws 362, a push block 363, and a push rod 364. The push-pull drive motor 361 is mounted on the block material laying truss 35; the two push-pull screws 362 are rotatably and parallelly mounted on the block material laying truss 35, and the two push-pull screws 362 are connected to the output shaft of the push-pull drive motor 361 via gears; each push-pull screw 362 is provided with a push block 363, which is threadedly connected to the push-pull screw 362; both ends of the push rod 364 are fixedly connected to the push blocks 363 on the two push-pull screws 362, respectively.

[0054] With this configuration, when transferring the mobile pallet 110 loaded with block materials from the feeding vehicle 4 to the construction laying vehicle 3, the mobile pallet 110 loaded with block materials is placed on the push-pull screw 362 and positioned by the push block 363 and push rod 364. The push-pull drive motor 361 drives the push-pull screw 362 to rotate, moving the mobile pallet 110 onto the block material laying truss 35. When the block materials in the mobile pallet 110 are removed, the push-pull drive motor 361 rotates in the opposite direction, pushing the empty mobile pallet 110 to the outside by the push block 363 and push rod 364, making it convenient to return the empty mobile pallet 110 to the feeding vehicle 4.

[0055] See Figures 4 to 8 In this embodiment, the block material laying mechanism 37 includes a laying hanger 371, a block material electric hoist 372, and a clamp 373. The laying hanger 371 is positioned above the movable pallet push-pull mechanism 36 and extends from one side of the construction laying work vehicle chassis 31. The block material electric hoist 372 is slidably mounted on the laying hanger 371. The clamp 373 is suspended on the block material electric hoist 372 and can move left and right along with the block material electric hoist 372 on the laying hanger 371. The block material electric hoist 372 can lower or lift the clamp 373, which is used to clamp the block material in the movable pallet 110 and lay it onto the working surface 100 to be laid.

[0056] With this setup, when laying block materials (precast concrete blocks), the block material electric hoist 372 is first moved along the laying hanger 371 to above the moving pallet 110. The block material electric hoist 372 lowers the clamp 373 and uses the clamp 373 to pick up the block material in the moving pallet 110. Then, the clamp 373 is lifted and moved along the laying hanger 371 with the block material to the working surface 100 to be laid on one side of the construction laying work vehicle chassis 31. Then, the block material electric hoist 372 lowers the clamp 373, and the clamp 373 is released, laying the block material on top of the geomembrane on the working surface 100. As the construction laying work vehicle 3 moves along the transport track 1, the precast concrete blocks are laid on the entire working surface 100.

[0057] Furthermore, the construction paving vehicle 3 is also equipped with a power system, and the construction paving vehicle 3 is connected to the traction winch on the gantry loading vehicle 2 via a steel wire rope. When the transport track 1 is erected on an inclined surface (the working surface 100 to be paved is an inclined surface), the construction paving vehicle 3 traveling on the inclined transport track 1 is powered by a combination of the winch and its own motor; when the transport track 1 is erected on a flat surface (the working surface 100 to be paved is a flat surface), it can be powered solely by the motor carried by the construction paving vehicle 3 itself.

[0058] See Figures 9 to 14 In this embodiment, the feeding vehicle 4 includes a low-level feeding and track disassembly / assembly vehicle 41, which mainly includes a low-level feeding vehicle base frame 411 and a low-level feeding loading box 412. The low-level feeding vehicle base frame 411 is slidably mounted on the transport track 1; the low-level feeding loading box 412 is mounted on the low-level feeding vehicle base frame 411, with one end hinged to the low-level feeding vehicle base frame 411 and the other end hinged to the piston rod of a low-level feeding hydraulic cylinder 416, the other end of which is also hinged to the low-level feeding vehicle base frame 411; a movable pallet support frame 413 is also provided inside the low-level feeding loading box 412.

[0059] During construction, the low-level material feeding and track dismantling vehicle 41 moves along the transport track 1 to the vicinity of the gantry loading vehicle 2. The gantry loading vehicle 2 hoists fine granular materials (such as sand and gravel) from the material transport vehicle into the low-level material feeding and track dismantling vehicle 41's low-level material feeding and track dismantling vehicle 41, and hoists block materials (such as the mobile pallet 110 containing precast concrete blocks) from the material transport vehicle onto the mobile pallet support frame 413 inside the low-level material feeding and loading vehicle 412. The low-level material feeding and track dismantling vehicle 41, loaded with materials, moves along the transport track 1 to the vicinity of the construction laying vehicle 3. The mobile pallet push-pull mechanism 36 on the construction paving vehicle 3 pulls the mobile pallet 110 containing block materials (precast concrete blocks) on the mobile pallet support frame 413 onto the block material paving truss 35 of the construction paving vehicle 3; the low-level feeding hydraulic cylinder 416 extends to lift one end of the low-level feeding loading box 412 upward, and the fine granular material is unloaded from the other end of the low-level feeding loading box 412 into the fine granular material trough 33 of the construction paving vehicle 3; thus, multiple materials can be transported from the material transport vehicle to the construction paving vehicle 3 for paving construction.

[0060] Further, see Figures 9 to 14The low-level feeding and rail disassembly / assembly vehicle 41 also includes a rail disassembly / assembly hanger 414 and a rail disassembly / assembly electric hoist 415. The rail disassembly / assembly hanger 414 is detachably mounted on the low-level feeding vehicle's bottom frame 411 and extends from one side of the bottom frame 411. The rail disassembly / assembly electric hoist 415 is slidably mounted on the rail disassembly / assembly hanger 414 for lifting and transporting the rail 1.

[0061] With this setup, after completing the paving work on one working surface 100, the transport rail 1 can be disassembled into sections. The disassembled transport rail 1 can be lifted by the electric hoist 415 and moved along the rail disassembly and assembly frame 414 to the next working surface 100. Then, the disassembled transport rail 1 sections are spliced ​​and erected above the next working surface. The construction paving vehicle 3 and the material delivery vehicle 4 are hoisted onto the spliced ​​transport rail 1. The gantry loading vehicle 2 is moved to one end of the spliced ​​transport rail 1, and the paving work on the next working surface 100 can then begin.

[0062] Similarly, a power system is also installed on the low-level feeding and rail dismantling vehicle 41, and this low-level feeding and rail dismantling vehicle 41 is also connected to the traction winch on the gantry loading vehicle 2 via a steel wire rope. When the transport rail 1 is erected on an inclined surface, the low-level feeding and rail dismantling vehicle 41 traveling on the inclined transport rail 1 is powered by a combination of the winch and its own motor; when the transport rail 1 is erected on a flat surface, it can be powered solely by the motor carried by the low-level feeding and rail dismantling vehicle 41 itself.

[0063] See Figures 15 to 18 In this embodiment, the feeding car 4 also includes a high-rise feeding car 42, which mainly includes a high-rise feeding car base frame 421 and a high-rise feeding loading box 422. The high-rise feeding car base frame 421 is slidably mounted on the transport track 1; the high-rise feeding loading box 422 is mounted on the high-rise feeding car base frame 421, with one end hinged to the high-rise feeding car base frame 421 and the other end hinged to the piston rod of a high-rise feeding hydraulic cylinder 426, the other end of which is also hinged to the high-rise feeding car base frame 421.

[0064] The high-rise material delivery vehicle 42 can be used to transport fine granular materials (sand, gravel) and can be used alternately with the low-rise material delivery and track assembly / disassembly vehicle 41. During construction, the high-rise material delivery vehicle 42 moves along the transport track 1 to the vicinity of the gantry loading vehicle 2. The gantry loading vehicle 2 lifts the fine granular materials from the material transport vehicle into the high-rise material delivery loading box 422 of the high-rise material delivery vehicle 42. Then, the high-rise material delivery vehicle 42 carries the materials along the transport track 1 to the vicinity of the construction laying vehicle 3. The high-rise material delivery hydraulic cylinder 426 lifts one end of the high-rise material delivery loading box 422, and the fine granular materials are unloaded from the other end of the high-rise material delivery loading box 422 into the fine granular material trough 33 of the construction laying vehicle 3.

[0065] Specifically, the elevated height of the high-rise material delivery vehicle 42's bottom frame 421 is higher than the overall height of the low-rise material delivery vehicle's bottom frame 411 and the low-rise material loading box 412 in the low-rise material delivery and track dismantling vehicle 41. This arrangement creates a passageway for the low-rise material delivery and track dismantling vehicle 41 to pass through below the high-rise material delivery vehicle's bottom frame 421. This allows the high-rise material delivery vehicle 42 and the low-rise material delivery and track dismantling vehicle 41 to easily coordinate and cooperate in transportation operations on the transport track 1. For example, when the low-rise material delivery and track dismantling vehicle 41 unloads material onto the construction laying vehicle 3, the high-rise material delivery vehicle 42 can be moved to the gantry loading vehicle 2 for loading. After the low-rise material delivery and track dismantling vehicle 41 finishes unloading, it returns to the gantry loading vehicle 2, while the high-rise material delivery vehicle 42 moves to the construction laying vehicle 3 for unloading. This process can be repeated, greatly improving construction efficiency.

[0066] Further, see Figures 15 to 18 In this embodiment, a movable door panel 423 is also provided at one end of the high-rise feeding and loading box 422 that is hinged to the high-rise feeding vehicle bottom frame 421. The upper edge of the movable door panel 423 is hinged to the upper part of the high-rise feeding and loading box 422. A connecting block 424 is provided at the upper part of the movable door panel 423. The connecting block 424 is hinged to one end of a door panel switch adjustment rod 425. The other end of the door panel switch adjustment rod 425 is hinged to the high-rise feeding vehicle bottom frame 421.

[0067] With this configuration, when the high-rise feeding hydraulic cylinder 426 pushes one end of the high-rise feeding and loading box 422 to lift, the door panel switch adjustment lever 425 drives the connecting block 424 and its movable door panel 423 to rotate around the hinge point between the movable door panel 423 and the upper part of the high-rise feeding and loading box 422, opening the lower part of the movable door panel 423, so that the material can be conveniently unloaded from one end of the high-rise feeding and loading box 422 into the fine granular material trough 33.

[0068] Similarly, a power system is also installed on the high-rise feeding car 42, and the high-rise feeding car 42 is also connected to the traction winch on the gantry loading car 2 via a steel wire rope. When the transport rail 1 is erected on an inclined plane, the high-rise feeding car 42 traveling on the inclined transport rail 1 is powered by a combination of the winch and its own motor; when the transport rail 1 is erected on a flat plane, it can be powered solely by the motor carried by the high-rise feeding car 42 itself.

[0069] See Figures 19 to 22 In this embodiment, the gantry loading trolley 2 mainly includes a gantry frame 21 and a hoisting electric hoist 22. The gantry frame 21 is located at one end of the transport track 1; the hoisting electric hoist 22 is installed on the gantry frame 21 and is used to hoist materials from the material transport vehicle onto the low-level feeding and track dismantling vehicle 41 and the high-level feeding vehicle 42. During construction, the material transport vehicle drives to the area below the gantry frame 21, and the hoisting electric hoist 22 is moved along the gantry frame 21 to above the material transport vehicle to lift the material container. Then, it is moved along the gantry frame 21 to above the low-level feeding and track dismantling vehicle 41 and the high-level feeding vehicle 42 to unload the materials onto them.

[0070] Further, see Figures 19 to 22 The gantry loading trolley 2 also includes a top traction winch 23, a reversing wheel 24, and a pull rope (not shown in the figure). The top traction winch 23 is installed on top of the gantry frame 21; the reversing wheel 24 is installed on the lower part of the gantry frame 21; the pull rope is wound around the top traction winch 23, and the pull rope passes around the reversing wheel 24 and connects to the low-level material feeding and track dismantling trolley 41, the high-level material feeding trolley 42, and the construction laying trolley 3. Through the top traction winch 23, the reversing wheel 24, and the pull rope, power can be provided for the movement of the low-level material feeding and track dismantling trolley 41, the high-level material feeding trolley 42, and the construction laying trolley 3 on the inclined transport track 1.

[0071] Further, see Figures 19 to 22 The gantry loading vehicle 2 also includes a tracked mobile chassis 25, on which the gantry frame 21 is mounted. With this configuration, the gantry loading vehicle 2 can be driven to move from one work station (a work surface to be laid 100) to the next work station via its own tracked mobile chassis 25.

[0072] The geomembrane laying method of this geomembrane laying system is as follows: Step S1: First, lay the transport track 1 above the work surface 100 to be laid, move the gantry loading work car 2 to one end of the transport track 1 and connect and fix it to the transport track 1, and hoist the construction laying work car 3 and the material delivery car 4 onto the transport track 1. Step S2: The material is hoisted from the material transport vehicle to the feeding vehicle 4 (low-level feeding and track disassembly and assembly vehicle 41 or high-level feeding vehicle 42) by the gantry loading work vehicle 2. The feeding vehicle 4 moves along the transport track 1 to the construction laying work vehicle 3 and transfers the material (sand, gravel) to the fine granular material trough 33 of the construction laying work vehicle 3. Step S3: The construction paving vehicle 3 moves along the transport track 1. During the movement, the fine granular material (sand, gravel) is evenly spread on the working surface 100 to be paved by the fine granular material feeding screw 32 and the rotary spreader 34, thereby completing the support layer paving work of one working surface. Step S4: After the support layer is laid, place the geomembrane roll at the geomembrane roll installation station 311 of the construction laying vehicle 3 and fix the starting end of the geomembrane in the support layer; move the construction laying vehicle 3 along the transport track 1 and lay the geomembrane on top of the support layer during the movement to complete the geomembrane laying of one working surface. Step S5: After the geomembrane is laid, a layer of gravel and sand is laid on top of the geomembrane, and then precast concrete blocks are laid. When laying the precast concrete blocks, the gantry loading vehicle 2 lifts the mobile pallet 110 containing the block material onto the delivery vehicle 4 (low-level delivery and track disassembly vehicle 41 or high-level delivery vehicle 42). The delivery vehicle 4 moves along the transport track 1 to the construction laying vehicle 3. The mobile pallet push-pull mechanism 36 in the construction laying vehicle 3 pulls the block material (precast concrete blocks) from the delivery vehicle 4 onto the construction laying vehicle 3. The construction laying vehicle 3 moves along the transport track 1. During the movement, the block material laying mechanism 37 lifts the block material in the mobile pallet 110 and lays it on top of the geomembrane on the working surface 100 to be laid, completing the protective layer laying of one working surface. After the laying is completed, the empty mobile pallet 110 is lifted back to the delivery vehicle 4 by the mobile pallet hanger 38.

[0073] After the support layer, geomembrane, and protective layer of one working surface are laid, a portion of the transport track 1 is disconnected. The track disassembly and assembly hanger 414 is installed on the bottom frame 411 of the low-level material delivery vehicle. The disconnected transport track 1 is moved above the next working surface 100 to be laid by the track disassembly and assembly hanger 414 and the track disassembly and assembly electric hoist 415 of the low-level material delivery and track disassembly and assembly vehicle 41. This process is repeated to move multiple disconnected transport track 1 sections above the next working surface 100 to be laid. Then, the multiple disconnected transport track 1 sections are connected to form a whole transport track 1. The gantry loading vehicle 2 is moved to one end of the reinstalled transport track 1 and fixed. The construction laying vehicle 3, the low-level material delivery and track disassembly and assembly vehicle 41, and the high-level material delivery vehicle 42 are hoisted onto the new transport track 1. Steps S2 to S5 are repeated to carry out the geomembrane laying construction of the next working surface 100 to be laid.

[0074] Overall, the geomembrane laying system of this invention can effectively reduce labor input and lower construction costs. Under the same time and workload, manual laying previously required approximately 40 people, while using this invention's geomembrane laying system, only 8 people are needed to complete the laying work. The laying quality is also greatly improved. All construction workers do not work on the laid geomembrane, effectively reducing human-caused damage. The materials are laid using mechanical equipment with care, reducing collisions between materials. Moreover, the geomembrane laying system of this invention has strong standardization of laying results. Experiments can be conducted before equipment construction to adjust equipment parameters and ensure that the laying meets engineering design requirements before full-scale laying. This uniform laying standard reduces the factors contributing to differences in laying results caused by variations in construction personnel during manual laying.

[0075] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
