[0002] A waterproof blanket, a bentonite composite waterproof blanket (GCL) is a new type of geosynthetic material. It is made of graded natural sodium-based bentonite particles and corresponding additives as raw materials, and through a needling process and equipment, the bentonite particles are fixed between a geotextile and a plastic woven fabric to form a blanket-shaped waterproof coiled material. The bentonite waterproof blanket not only has all the characteristics of geotechnical materials but also has excellent waterproof (seepage) performance. It is used as an important waterproof and anti-seepage material in the current renovation processes of river channels, inland artificial lakes, reservoirs, aquaculture, and landfills.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Embodiment 1

[0025] Please refer to Figures 1-5 as shown, a device for assisting in laying bentonite waterproof blankets includes: a bottom plate 1, an idler device 2 fixed to the top of the bottom plate 1, a drive motor 3 fixed above the bottom plate 1, a lead screw 4 fixed to the output end of the drive motor 3, and a hydraulic rod 5 fixed above the lead screw 4;

[0026] At the top of the bottom plate 1, two support plates 6 are fixed. A pressing roller 7 is rotatably installed between the two support plates 6. One side of the support plate 6 is fixed with a connecting rod 8. One end of the connecting rod 8 is fixed with a guide plate 9. A sliding hole 10 is formed in the top surface of the guide plate 9. A sliding block 11 is slidably installed inside the sliding hole 10. A pulling rod 12 is fixed to the top of the sliding block 11. An installation column 13 is fixed to the bottom of the sliding block 11. The material of the installation column 13 has elasticity. A smoothing plate 14 is fixed to the bottom end of the installation column 13.

[0027] During use, the bottom plate 1 supports the roller device 2. Then, the waterproof blanket is placed on the roller device 2. When laying, first release a part of the waterproof blanket into the guide plate 9, and then the staff fixes the waterproof blanket passing through the guide plate 9 to the ground. At this time, the staff manually moves the pulling rod 12, so that the sliding block 11 can move in the sliding hole 10. Therefore, the smoothing plate 14 can scrape and smooth the waterproof blanket, remove the wrinkles and uneven positions on the waterproof blanket, avoid accumulation, and is beneficial to more uniform and flat laying in the follow-up.

[0028] Embodiment Two

[0029] As a specific implementation manner of the present invention, please refer to Figures 2-5 As shown, the driving motor 3 is fixedly connected inside the guide plate 9. The outer wall of the lead screw 4 is threadedly connected with a lower pressing plate 15. The hydraulic rod 5 is fixedly connected inside the lower pressing plate 15. An upper pressing plate 16 is slidably connected above the lower pressing plate 15. The telescopic end of the hydraulic rod 5 is fixedly connected to the bottom of the upper pressing plate 16. Electric push rods 17 are respectively fixed on both sides of the roller device 2. The telescopic ends of the electric push rods 17 are fixed with mounting rods 18. Fixing plates 19 are respectively fixed at both ends of the mounting rod 18. A compaction roller 20 is fixed to the bottom of the left fixing plate 19. A slag cleaning plate 21 is fixed to the bottom of the right fixing plate 19.

[0030] During use, the hydraulic rod 5 makes the lower pressing plate 15 and the upper pressing plate 16 fit together, so that the waterproof blanket can be fitted and fixed. At this time, the output end of the driving motor 3 rotates to make the lead screw 4 rotate, so that the lower pressing plate 15 can move. Therefore, it can avoid accumulation when the waterproof blanket is loosened, ensuring the flatness and cleanliness of the blanket. The electric push rod 17 can drive the mounting rod 18 to move up and down, so that the positions of the compaction roller 20 and the slag cleaning plate 21 can be adjusted, improving the practicability.

[0031] Embodiment Three

[0032] As a specific implementation manner of the present invention, please refer to Figures 2-4As shown, limit plates 22 are respectively fixed on both sides of the bottom plate 1. A limit block 23 is slidably installed inside the limit plate 22. One side of the limit block 23 is fixedly connected to one side of the fixed plate 19. A telescopic rod 24 is fixed to the bottom of the bottom plate 1. A moving wheel 25 is fixed to the bottom end of the telescopic rod 24. A spring 26 is fixed to the bottom of the bottom plate 1. The spring 26 is sleeved on the outer wall of the telescopic rod 24. The bottom end of the spring 26 is fixedly connected to the top end of the moving wheel 25. Two push rods 27 are fixed to the top of the bottom plate 1. The installation rod 18 is U-shaped.

[0033] During use, the limit plate 22 and the limit block 23 can make the installation rod 18 move more smoothly, which is beneficial to making the compaction roller 20 and the slag cleaning plate 21 fit the ground more neatly, thus improving the compaction and slag cleaning efficiency and reducing the impact on laying. The spring 26 and the telescopic rod 24 can make the moving wheel 25 adapt to various ground types. The push rod 27 can facilitate the staff to push, making the movement more time-saving and labor-saving, and also beneficial for the staff to better control and improve stability.

[0034] Working principle: During use, the staff first place the waterproof blanket on the roller device 2, and then pull the waterproof blanket into the guide plate 9 during laying. When entering the guide plate 9, the waterproof blanket is fixed by the cooperation of the upper pressing plate 16 and the lower pressing plate 15. During fixation, the waterproof blanket is pressed by the pressing roller 7 to ensure that the waterproof blanket does not extend outwards during laying, thus avoiding excessive diffusion range and difficulty in laying. After fixation, the staff move the smoothing plate 14 to remove the wrinkles on the waterproof blanket. For positions with more wrinkles, the staff can scrape repeatedly to ensure that it is more uniform and flat during laying. And the guide plate 9 can block and limit the waterproof blanket to ensure that there is no excessive deviation during laying, improving the laying effect and the aesthetics after laying.
