Compared with the existing way of laying geomembrane manually, the geomembrane laying system of the invention can greatly reduce the labor input, reduce the construction cost, improve the laying quality and shorten the construction period.

Specifically, referring to Figs. 4-8, in this embodiment, the construction laying work car 3 mainly includes a construction laying work underframe 31, a fine granular material feeding screw 32, a fine granular material trough 33 and a rotating spreader 34.

After laying to form the support layer, the geomembrane reel is placed on the geomembrane drum installation station 311 on the construction laying work underframe 31 of the construction laying work work car, and the initial end of the geomembrane is fixed in the support layer; as the construction laying work car 3 moves along the transport track 1, a layer of geomembrane is laid above the support layer.

Referring to Figs. 4-8, in this embodiment, the construction paving trolley 3 further includes a block material laying truss 35, a moving tray push-pull mechanism 36, a block material laying mechanism 37 and a moving tray hanger 38. Where, the block material laying truss 35 is installed on the construction laying work underframe 31 of NS 600384 construction laying work work car; the moving tray push-pull mechanism 36 is installed on the block material laying truss 35 for pulling the movable tray 110 loaded with block materials (such as concrete precast blocks) from the feeding work car 4 to the construction laying work car 3; the block material laying mechanism 37 is installed above the block material laying truss 35 for laying the block material in the movable tray 110 on the working surface to be laid 100; the moving tray hanger 38 is installed above the moving tray push-pull mechanism 36, and is used for hanging the empty movable tray 110 back from the construction laying work car 3 to the feeding work car 4.

After the geomembrane is laid, fine granular materials (gravel and sand) are laid above the geomembrane, and then concrete precast blocks are laid. During the construction of concrete precast blocks, the movable tray 110 loaded with block materials (concrete precast blocks) on the feeding work car 4 is pulled onto the block material laying truss 35 through the moving pallet push-pull mechanism 36 on the construction laying work car 3; during the movement of the construction laying car 3 along with the transport track 1, the block materials in the movable tray 110 are clamped and laid on the geomembrane by the block material laying mechanism 37, and a protective layer is formed above the geomembrane; the empty movable tray 110 is hoisted back from the construction laying work car 3 to the feeding work car 4 by the moving tray hanger 38.

In this embodiment, the moving tray push-pull mechanism 36 includes a push-pull drive motor 361, two push-pull wire rods 362, a push block 363 and a push rod 364. The push-pull drive motor 361 is installed on the block material laying truss 35; two push-pull wire rods 362 are rotatably installed in parallel on the massive material laying truss 35, and the two push-pull wire rods 362 are connected with the output shaft of the push-pull driving motor 361 through gears; each push-pull wire rod 362 is provided with the push block 363, and the push block 363 is in threaded connection with the push-pull rod 362; both ends of the push rod 364 are respectively fixedly connected with the push blocks 363 on the two push-pull wire rods 362.

pull drive motor 361 rotates in the opposite direction, and the empty movable tray 110 1$)600384 pushed to the outside through the push block 363 and the push rod 364, so that the empty movable tray 110 can be conveniently sent back to the feeding work car 4.

Referring to Figs. 4-8, in this embodiment, the block material laying mechanism 37 includes a laying hanger 371, a block material electric hoist 372 and a gripper 373.

Among them, the laying hanger 371 is arranged above the moving pallet push-pull mechanism 36 and extends from one side of the construction laying work underframe 31; the block material electric hoist 372 is slidably mounted on the laying hanger 371; the gripper 373 is hung on the block material electric hoist 372, which 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 put down or lift the gripper 373, which is used to clamp the block material in the movable tray 110 and lay it on the working surface to be laid 100.

Further, a power system is also provided on the construction laying work car 3, and the construction laying work car 3 is connected with the traction winch on the gantry loading work car 2 through a steel wire rope. When the transport track 1 is erected on an inclined plane (the working surface to be laid 100 is an inclined plane), the construction laying work car 3 running on the inclined transport track 1 adopts a winch and a motor carried by itself to jointly provide power; when the transport track 1 is erected on a plane (the working surface to be laid 100 is a plane), the power can be provided only by the motor carried by the construction track 3 itself.

Referring to Figs. 9-14, in this embodiment, the feeding work car 4 includes a low- level feeding and rail disassembly car 41, which mainly includes a low-level feeding underframe 411 and a low-level feeding loading box 412. Among them, the low-level feeding underframe 411 is slidably arranged on the transport track 1; the low-level 500384 feeding loading box 412 is arranged on the low-level feeding underframe 411 of the low- level feeding and charging car, one end of the low-level feeding loading box 412 is hinged on the low-level feeding underframe 411, and the other end of the low-level feeding loading box 412 is hinged with the piston rod of a low-level feeding hydraulic cylinder 416, and the other end of the low-level feeding hydraulic cylinder 416 is hinged on the low-level feeding underframe 411; a moving tray support frame 413 is also provided in the low-level feeding loading box 412.

During construction, the low-level feeding and rail disassembly car 41 moves along the transport track 1 to the vicinity of the gantry feeding work car 2, and the gantry feeding work work car 2 lifts fine granular materials (such as sand and gravel) on the material transport work car into the low-level feeding loading box 412 of the low-level feeding and rail disassembly car 41, and lifts block materials (such as the movable tray 110 with concrete precast blocks) on the moving tray support frame 413 in the low-level feeding loading box 412; the low-level feeding and rail disassembly car 41 loaded with materials moves to the vicinity of the construction laying work car 3 along the transport track 1; the movable tray push-pull mechanism 36 on the construction laying work car 3 pulls the movable tray 110 loaded with massive materials (concrete precast blocks) on the moving tray support frame 413 onto the block material laying truss 35 of the construction laying work car 3; the low-level feeding hydraulic cylinder 416 extends out to lift one end of the low-level feeding loading box 412 upward, and fine granular materials are discharged from the other end of the low-level feeding loading box 412 into the fine granular material trough 33 of the construction and laying work work car 3; it is possible to transport various materials from the material transport work car to the construction laying work car 3 for laying construction.

Further, referring to Figs. 9-14, the low-level feeding and rail disassembly car 41 also includes a rail disassembly hanger 414 and a rail disassembly electric hoist 415.

Among them, the rail disassembly hanger 414 is detachably installed on the low-level feeding underframe 411, and the rail disassembly hanger 414 protrudes from one side of the low-level feeding underframe 411; the rail disassembly electric hoist 415 is slidably installed on the rail disassembly hanger 414 for hoisting the transport track 1.

In this way, after the laying operation of a working surface to be laid 100 is completed, the transport track 1 can be disassembled in sections, the disassembled transport track 1 can be hoisted by the rail disassembly electric hoist 415, and moved to the next working surface to be laid 100 along the rail disassembly hanger 414, and then the multi-section disassembled transport track 1 can be spliced and erected above the 50038 4 next working face, and the construction laying work car 3 and the feeding work car 4 can be hoisted onto the spliced transport track 1, and moving the gantry loading work car 2 to one end of the spliced transport track 1, and then the next working surface to be laid 100 can be laid.

Similarly, the low-level feeding and rail disassembly car 41 is also equipped with a power system, and this work car is connected to the traction winch on the gantry loading work car 2 through a steel cable. When the transport track 1 is set up on a slope, the low-level feeding and rail disassembly work car 41 traveling on the inclined transport track 1 is powered by both the winch and its own motor; when the transport track 1 is set up on a flat surface, the work car can be powered solely by its own motor.

Referring to Figs. 15-18, in this embodiment, the feeding work car 4 also includes a high-level feeder 42, which mainly consists of a high-level feeding car underframe 421 and a high-level feeding loading box 422.

The high-level feeder 42 is used to transport fine granular materials (such as sand and gravel) and can work in tandem with the low-level feeding rail disassembly work car 41. During construction, the high-level feeder 42 moves along the transport track 1 to the vicinity of the gantry loading work car 2, which lifts the fine granular materials from the material transport work car into the high-level feeding loading box 422; the high- level feeding work car 42 then carries the materials along the transport track 1 to the vicinity of the construction laying work car 3; the high-level feeding hydraulic cylinder 426 lifts one end of the high-level feeding loading box 422, allowing the fine granular materials to be discharged from the other end into the fine granular material trough 33 of the construction laying work car 3.

Specifically, the overhead height of the high-level feeding car underframe 421 of the high-level feeder 42 is higher than the overall height of the high-level feeding car underframe 411 and the low-level feeding loading box 412 of the low-level feeding and rail disassembly car 41; in this way, a passage for the low-level feeding and rail disassembly work car 41 to pass through is formed under the high-level feeding car underframe 421. This setup allows the high-level feeder 42 and the low-level feeding and rail disassembly car 41 to work alternately on the transport track 1 efficiently. FP{600384 example, while the low-level feeding and rail disassembly car 41 is unloading materials to the construction laying work car 3, the high-level feeder 42 can move to the gantry loading work car 2 for loading; once unloading is complete, the low-level feeding and rail disassembly car 41 returns to the gantry loading work car 2, while the high-level feeder 42 moves to the construction laying work car 3 to unload materials, this alternating process significantly improves construction efficiency.

Further, referring to Figs. 15-18, in this embodiment, the end of the high-level feeding loading box 422 hinged to the high-level feeding car underframe 421 is also equipped with a movable door panel 423, the upper edge of the movable door panel 423 is hinged to the upper part of the high-level feeding loading box 422, and a connecting block 424 is attached to 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 which is hinged to the high-level feeding car underframe 421.

With this setup, when the high-level feeding hydraulic cylinder 426 lifts one end of the high-level feeding loading box 422, the door panel switch adjustment rod 425 drives the connecting block 424 and the movable door panel 423 to rotate around the hinge point between the movable door panel 423 and the high-level feeding loading box 422, opening the lower part of the movable door panel 423, this allows materials to be easily discharged from the high-level feeding loading box 422 into the fine granular material trough 33.

Similarly, the high-level feeder 42 is also equipped with a power system and is connected to the traction winch on the gantry loading work car 2 through a steel cable.

When the transport track 1 is set up on a slope, the high-level feeder 42 traveling on the inclined track is powered by both the winch and its own motor; when the transport track 1 is erected on a plane, it may only be powered by the motor carried by the high-level feeder 42 itself.

Referring to Figs. 19-22, in this embodiment, the gantry loading work car 2 mainly consists of a gantry frame 21 and a lifting electric hoist 22. The gantry frame 21 is positioned at one end of the transport track 1, and the lifting electric hoist 22 is mounted on the gantry frame 21; the lifting electric hoist 22 is used to lift materials from the material transport work car onto the low-level feeding and rail disassembly car 41 and the high-level feeder 42. During construction, the material transport work car moves under the gantry frame 21, after the material container is lifted, it will be moved to the upper part of the low-level feeding and rail disassembly car 41 and the high-level feeder

42 along the gantry frame 21, and the materials will be unloaded onto the low-level 500384 feeding and rail disassembly car 41 and the high-level feeder 42.

Additionally, referring to Figs. 19-22, the gantry loading work car 2 also includes a top traction winch 23, a steering wheel 24, and a tension rope (not shown in the figures).

The top traction winch 23 is mounted on the top of the gantry frame 21, and the steering wheel 24 is installed at the lower part of the gantry frame 21; the tension rope is wound around the top traction winch 23 and passes over the steering wheel 24 to connect with the low-level feeding and rail disassembly car 41, the high-level feeder 42, and the construction laying work car 3. Through the top traction winch 23, the steering wheel 24 and the tension rope, power can be provided for the low-level feeding and rail disassembly car 41, the high-level feeder 42 and the construction laying work car 3 to move on the inclined transport track 1.

Further, referring to Figs. 19-22, the gantry loading work car 2 further includes a crawler moving chassis 25, and the gantry frame 21 is mounted on the crawler moving chassis 25. With this arrangement, the gantry loading work car 2 can be driven to move from one station (a working surface to be laid 100) to the next station by the crawler moving chassis 25 carried by itself.

The construction method for the system for geomembrane laying is as follows:

S1: first, lay the transport track 1 above the working surface to be laid 100, move the gantry loading work car 2 to one end of the transport track 1 and secure it, then, hoist the construction laying work car 3 and the feeding work car 4 onto the transport track 1.

S2: Use the gantry loading work car 2 to lift materials from the material transport work car onto the feeding work car 4 (either the low-level feeding and rail disassembly car 41 or the high-level feeder 42). The feeding work car 4 moves along the transport track 1 to the construction laying work car 3 and transfers the materials (sand, gravel) into the fine granular material trough 33 of the construction laying work car 3.

S3: The construction laying work car 3 moves along the transport track 1, spreading the fine granular materials (sand, gravel) evenly on the working surface to be laid 100 using the fine granular material feeding screw 32 and the rotating spreader 34, completing the support layer for one work surface.

S4: After completing the support layer, place a geomembrane roll on the geomembrane drum installation station 311 of the construction laying work car 3, fix the starting end of the geomembrane to the support layer; as the construction laying work car 3 moves along the transport track 1, it lays the geomembrane over the support a 600384 completing the geomembrane laying for one work surface.

S5: After laying the geomembrane, spread another layer of gravel and sand over it, followed by concrete precast blocks; when laying the concrete precast blocks, the gantry loading work car 2 lifts the movable tray 110 containing the block materials onto the feeding work car 4 (either the low-level feeding and rail disassembly car 41 or the high-level feeder 42), the feeding work car 4 moves along the transport track 1 to the construction laying work car 3; the moving tray push-pull mechanism 36 in the construction laying work car 3 pulls the block materials (concrete precast blocks) from the feeding work car 4 onto the construction laying work car 3; as the construction laying work car 3 moves along the transport track 1, the block material laying mechanism 37 lifts and lays the block materials from the movable tray 110 onto the geomembrane on the working surface to be laid 100, completing the protective layer for one work surface; after laying, the empty movable tray 110 is hoisted back onto the feeding work car 4 using the moving tray hanger 38.

After completing the support layer, geomembrane, and protective layer for one work surface, disconnect a section of the transport track 1, install the rail disassembly hanger 414 on the low-level feeding underframe 411, use the rail disassembly hanger 414 and the rail disassembly electric hoist 415 on the low-level feeding and rail disassembly car 41 to move the disconnected transport track 1 to the next working surface to be laid 100; repeat this process to move multiple disconnected sections of the transport track 1 to the next work surface, then reconnect them to form a continuous transport track 1, move the gantry loading work car 2 to the newly installed end of the transport track 1 and secure it, hoist the construction laying work car 3, the low-level feeding and rail disassembly car 41, and the high-level feeder 42 onto the new transport track 1; repeat Steps S2-S5 to perform geomembrane laying on the next working surface to be laid 100.

Overall, the system for geomembrane laying of the invention effectively reduces labor input and construction costs. For the same amount of work and time, the system requires only 8 workers compared to the approximately 40 workers needed for manual laying; the system also significantly improves laying quality, as all construction personnel work off the laid geomembrane, minimizing human-induced damage, materials are handled gently by mechanical equipment, reducing collisions; moreover, the laying achievements of the geomembrane laying system are standardized, and experiments can be made before equipment construction, and equipment parameters can be adjusted to ensure that the laying meets the engineering design requirements 500384 and then the laying standards are unified, thus reducing the factors of different laying effects caused by the differences of construction personnel in manual laying.
