Technical Field

[0001] This invention relates to the field of waterproof blanket laying technology, and more particularly to a device for laying sodium-based bentonite waterproof blankets. Background Technology

[0002] Sodium-based bentonite waterproofing blankets are high-performance seepage-proof materials with natural sodium-based bentonite as the core material. Bentonite particles are fixed between geotextile composite layers through processes such as needle punching and adhesive bonding to form a barrier that combines physical protection and chemical seepage prevention properties. They are widely used in seepage prevention geosynthetic materials for artificial lakes and water features, landfills, underground garages, rooftop gardens, pools, oil depots, and chemical storage yards.

[0003] Especially when waterproofing foundation pits or reservoir areas, waterproof blankets are commonly used as part of the waterproofing structure. In the existing technology, the laying of waterproof blankets is generally done manually, with machines as a supplement. Due to technological advancements, some auxiliary laying devices have begun to be used to reduce manual labor. For example, Chinese utility model patent application number CN202421027402.6 discloses a bentonite waterproof blanket laying device, and Chinese invention patent application number CN202110907430.1 discloses a sodium-based bentonite waterproof blanket laying device. Both of these patents can replace manual labor to lay waterproof blankets. However, both of these patents can only lay the waterproof blanket flat, and manual overlapping of adjacent waterproof blankets is still required to prevent leakage between adjacent waterproof blankets. To address this problem, this invention proposes a sodium-based bentonite waterproof blanket laying device. Summary of the Invention

[0016] Compared with the prior art, the present invention provides a device for laying sodium-based bentonite waterproof blankets, which has the following beneficial effects.

[0017] 1. The present invention, through the setting of the spreading component, can spread bentonite at the overlapping position of adjacent waterproof blankets when laying waterproof blankets, and then use the compaction component to compact and combine the upper and lower waterproof blankets at the overlapping position, thereby achieving the effect of automatic overlapping, thus solving the problem of the need for manual overlapping of adjacent waterproof blankets in the prior art.

[0018] 2. In this invention, the water spraying component can be mixed with bentonite, causing the bentonite to expand upon contact with water and form a high-density gel-like sealing layer between two waterproof blankets, thereby improving the waterproof effect.

[0038] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the invention in a schematic manner, and therefore only show the components relevant to the invention.

[0039] Please refer to Figures 1-12 A device for laying sodium-based bentonite waterproof blankets includes a support assembly for supporting the waterproof blanket rolls, a conveying assembly for conveying and laying the waterproof blanket, a spreading assembly for spreading bentonite at overlapping positions, and a compaction assembly for compacting the overlapping positions. The support assembly, conveying assembly, spreading assembly, and compaction assembly are all mounted on a frame, which is connected to a traction machine. A leveling assembly for leveling the base layer is also provided at the bottom of the frame.

[0040] In a specific embodiment of the present invention, the support component is mainly used to support the waterproof blanket roll to be laid. During the laying process, the device is moved by the traction machinery, and then the waterproof blanket roll is unfolded and laid on the base layer by the conveying component. The edge of the upper waterproof blanket 34 should overlap with the edge of the adjacent lower waterproof blanket 35, i.e., the overlap position. During the laying process, the material spreading component spreads bentonite mixed with water at the overlap position of the lower waterproof blanket 35 (using bentonite to improve the sealing of the overlap between the upper and lower waterproof blankets). Then, the overlap position of the upper waterproof blanket 34 covers the overlap position of the lower waterproof blanket 35, and the upper waterproof blanket 34 and the lower waterproof blanket 35 are compacted by the compaction component to further improve the sealing. In this way, the automatic overlapping effect can be achieved, reducing the intensity of manual labor.

[0041] Specifically, the frame includes a front frame 1 and a rear frame 14. The rear end of the front frame 1 is fixedly connected to the front end of the rear frame 14. The support component and the material spreading component are set on the front frame 1, and the conveying component, the compaction component and the leveling component are set on the rear frame 14.

[0042] A connecting frame 3 is fixedly installed at the front end of the front frame 1. The front frame 1 is connected to the traction machinery through the connecting frame 3. The traction machinery can be an existing wheeled vehicle or a tracked vehicle. For example, in this solution, a tractor is used to traction the device. The connecting frame 3 is connected to the traction device at the rear of the tractor. The specific connection method can refer to the connection method between the tractor and the rotary tiller. In other embodiments, the specific structure of the connecting frame 3 can be adapted to the traction device of the traction machinery. That is, the main function of the connecting frame 3 is to connect the frame and the traction machinery together, and use the traction machinery to drive the device to move.

[0043] The leveling assembly includes a leveling roller 15 and a first scraper 16. The leveling roller 15 is rotatably mounted at the bottom rear of the rear frame 14, and the first scraper 16 is fixedly mounted at the bottom middle of the rear frame 14. The first scraper 16 is inclined, that is, one end is forward and the other end is backward, and the forward end is close to the spreading outlet of the spreading assembly.

[0044] Specifically, the bottom of the first scraper 16 is shovel-shaped, which can level the base layer. During the leveling process, excess debris, such as clods of soil and stones, can be pushed forward by the first scraper 16. Since the first scraper 16 is set at an angle, the excess debris pushed away will move towards the rear end of the first scraper 16 as it moves, until it leaves the first scraper 16. This avoids the effect of increasing the load on the first scraper 16 by having debris at the first scraper 16. This achieves the effect of leveling the base layer. After the first scraper 16 cleans the excess debris on the base layer, the leveling roller 15 rolls the base layer to make it even flatter. This avoids the problem of damage to the waterproof blanket or reduction of the waterproof effect due to uneven base layer.

[0045] The material spreading assembly includes a storage section and a spreading section. The storage section includes a hopper 2. The bottom of the hopper 2 has two discharge ports 32. The hopper 2 is also equipped with a material conveying assembly for pushing the bentonite to the discharge ports 32. The hopper 2 is fixedly installed on the upper part of the front frame 1. The discharge ports 32 are close to one end of the hopper 2.

[0046] In this scheme, the material conveying assembly uses a screw conveyor to move the bentonite. Specifically, the lower part of the hopper 2 consists of two U-shaped hoppers, each of which is equipped with a rotating screw conveyor plate 29. The screw conveyor plate 29 can be driven to rotate by a motor. The rotation of the screw conveyor plate 29 is used to push the bentonite, so that the bentonite can move towards the discharge port 32 and then be discharged from the discharge port 32.

[0047] To improve the smoothness of material feeding, a third vibrator 26 is installed at the discharge port 32 of the silo 2 in this solution. The third vibrator 26 is fixedly installed on the outer wall of the silo 2 and located near the discharge port 32. The vibration of the third vibrator 26 avoids the problem of bentonite accumulating at the discharge port 32, thereby improving the smoothness of bentonite feeding.

[0048] The material spreading section includes a first feeding box 18 and a second feeding box 17, which are fixedly connected. The top inlets of the first feeding box 18 and the second feeding box 17 are located at the two discharge ports 32 of the hopper 2, respectively.

[0049] By setting up a first feeding box 18 and a second feeding box 17, the bentonite can be spread in batches, avoiding the problem of insufficient mixing of bentonite and water and poor sealing caused by spreading it all at once. Specifically, using two feeding boxes can disperse the amount of bentonite, thereby increasing the contact area with water and improving the mixing effect.

[0050] The bottom of the second feeding box 17 is higher than the bottom of the first feeding box 18. This arrangement can prevent the second feeding box 17 from pushing away the bentonite spread in the first feeding box 18.

[0051] Specifically, two discharge frames are fixedly installed at the bottom of the silo 2, corresponding to two discharge ports 32 respectively. The two discharge frames are located in the top inlet of the first discharge box 18 and the top inlet of the second discharge box 17 respectively. This arrangement can both prevent bentonite from spilling outward and limit the range of movement of the first discharge box 18 and the second discharge box 17.

[0052] The material spreading unit also includes a water spraying assembly. There are two sets of water spraying assemblies, which are fixedly installed on the upper part of the first feeding box 18 and the second feeding box 17, respectively, to spray water into the interior of the first feeding box 18 and the second feeding box 17.

[0053] The purpose of spraying water is to allow the dry bentonite powder to absorb moisture and initially expand to form a gel-like structure, laying the foundation for the formation of a continuous impermeable layer after subsequent compaction. This method of mixing bentonite and water can achieve the effect of mixing and using immediately.

[0054] Specifically, the water spray assembly includes an atomizing nozzle 31, a water pipe 30, and a fixing cover 19. The atomizing nozzle 31 is fixedly mounted on the water pipe 30, and the two are internally connected. The water pipe 30 is fixedly mounted inside the fixing cover 19, and the spray direction of the atomizing nozzle 31 is towards the inside of the corresponding feed box. The fixing covers 19 in the two sets of water spray assemblies are respectively fixedly mounted on the upper part of the first feed box 18 and the upper part of the second feed box 17. The outer end of the water pipe 30 is connected to the water source through a high-pressure water pump, that is, water is drawn by the high-pressure water pump and then sprayed out from the atomizing nozzle 31 to achieve the effect of adding water to the bentonite. The water source can be stored in a water tank, which can be fixedly mounted on the inner bottom of the front frame 1. The high-pressure water pump can be fixedly mounted on the outside of the water tank or fixedly mounted on the front frame 1 at a suitable position.

[0055] By using atomizing nozzle 31, the sprayed water can be made into a mist, increasing the contact area with bentonite, thereby improving the water absorption efficiency of bentonite, accelerating the water penetration efficiency, and shortening the waiting time after bentonite absorbs water (in the existing technology, after bentonite is mixed with water, it cannot be directly compacted, but needs to wait for full penetration to avoid unwetted dry powder residue), thus improving construction efficiency.

[0056] The top of the first feeding box 18 is hinged to a support 25, which is fixedly installed on the side of the frame. A tension spring 24 is installed between the first feeding box 18 and the support 25. The tension spring 24 can apply a downward force to the first feeding box 18, so that the bottom of the first feeding box 18 can be in close contact with the lower waterproof blanket 35, thereby achieving a certain leveling effect on the overlapping position of the lower waterproof blanket 35.

[0057] A second vibrator 23 is fixedly installed at the lower part of the first feeding box 18. The second vibrator 23 can make the first feeding box 18 and the second feeding box 17 vibrate, preventing the bentonite from piling up in the feeding box and sliding down. At the same time, due to the vibration, the bentonite can be turned over under the vibration, thereby improving the thorough mixing with water and further improving the mixing efficiency of bentonite and water, so that water can better penetrate the bentonite. Several partitions 33 are fixedly installed inside the first feeding box 18 and the second feeding box 17. The partitions 33 can divide the inside of the feeding box into several channels, allowing the bentonite to enter each channel for mixing with water. This can achieve the following effects: 1. Preventing the bentonite from piling up in the feeding box and improving the mixing effect with water; 2. Achieving a more uniform spreading effect and avoiding the problem of uneven distribution of bentonite on the lower waterproof blanket 35; 3. When laying on a slope with a certain degree of inclination, it can avoid the problem of bentonite piling up on one side of the feeding box due to gravity.

[0058] A cleaning component is provided at the bottom of the first feeding box 18. The cleaning component is used to clean the overlapping positions of the lower waterproof blanket 35.

[0059] Specifically, the cleaning assembly includes a fixed plate 20, a second scraper 22, and an elastic sheet 21. The fixed plate 20 is fixedly disposed at the lower part of the first feeding box 18. The top end of the second scraper 22 is hinged to the fixed plate 20. The elastic sheet 21 is fixedly disposed between the second scraper 22 and the fixed plate 20, providing a downward force to the second scraper 22. This arrangement can reduce the impact of the second vibrator 23 on the second scraper 22. When the first feeding box 18 vibrates, the second scraper 22 will also be affected by the vibration. However, due to the elastic sheet 21, the bottom end of the second scraper 22 can continuously contact the lower waterproof blanket 35. In use, the second scraper 22 is used to clean the overlapping position of the lower waterproof blanket 35 to prevent debris from affecting the subsequent bonding with the upper waterproof blanket 34.

[0060] The second scraper 22 is also inclined, with one end forward and the other end backward, at the same inclination angle as the first scraper 16. This arrangement allows the debris on the lower waterproof blanket 35 to be pushed away from the lower waterproof blanket 35 and fall onto the base layer, where it is then scraped away by the first scraper 16.

[0061] The conveying assembly includes a roller frame 13, on which two conveying rollers 6 are rotatably mounted. The conveying rollers 6 are driven to rotate by a drive assembly. The roller frame 13 is fixedly mounted at the rear end of the frame. In use, the waterproof blanket passes between the two conveying rollers 6, meaning the two conveying rollers 6 can clamp the waterproof blanket. As the two conveying rollers 6 rotate, the waterproof blanket roll can be unfolded. The drive assembly can be a motor and a reducer, using the motor to drive the conveying rollers 6 to rotate, thus conveying and unfolding the waterproof blanket roll. The roller frame 13 is fixedly mounted at the rear end of the rear frame 14. A guide roller 4 is provided in the upper middle part of the rear frame 14. The guide roller 4 is located between the support assembly and the conveying assembly, serving as a support transition and preventing direct friction between the waterproof blanket and the top of the rear frame 14.

[0062] The compaction assembly includes a fixed frame 10, a pressure plate 12, and a pressure roller 28. The pressure plate 12 is mounted on the fixed frame 10 via a first connecting assembly. A first vibrator 9 is provided on the first connecting assembly. The pressure roller 28 is mounted on the fixed frame 10 via a second connecting assembly. The fixed frame 10 is fixedly mounted on a roller frame 13.

[0063] The first connecting assembly includes a slide rod 27 and a second spring 11. The slide rod 27 is slidably mounted on the fixed frame 10. The first vibrator 9 is fixedly mounted on the top end of the slide rod 27. The pressure plate 12 is fixedly mounted on the bottom end of the slide rod 27. The second spring 11 is sleeved on the slide rod 27. The top end of the second spring 11 is fixedly connected to the fixed frame 10, and the bottom end is fixedly connected to the bottom end of the slide rod 27. In use, the second spring 11 applies downward pressure to the pressure plate 12, so that the pressure plate 12 can be pressed tightly on the top surface of the overlapping position of the upper waterproof blanket 34, and the vibration of the first vibrator 9 is used to achieve the effect of vibration compaction.

[0064] The second connecting assembly includes a bracket 7 and a first spring 8. The bracket 7 is slidably mounted on the fixed frame 10, and the first spring 8 is sleeved on the bracket 7. The top end of the first spring 8 is fixedly connected to the fixed frame 10, and the bottom end is fixedly connected to the lower part of the bracket 7. At least two sets of the second connecting assembly are provided. A rotating shaft is rotatably mounted on the bottom of the bracket 7, and a pressure roller 28 is fixedly mounted on the rotating shaft. In use, the first spring 8 applies a downward force to the bracket 7, so that the pressure roller 28 can press on the non-overlapping part of the upper waterproof blanket 34, making it in close contact with the base layer.

[0065] The support assembly includes a material rack 5, which is detachably mounted on the frame. Specifically, the material rack 5 is detachably mounted on the front frame 1. A rotating shaft is provided on the top of the material rack 5, and the waterproof blanket roll is mounted on the rotating shaft.

[0066] It should be noted that the first vibrator 9, the second vibrator 23, and the third vibrator 26 in this scheme are all electric vibrators, using existing conventional equipment; in addition, the electricity required in this scheme can be obtained from the traction machinery. For example, if a tractor is used as the traction machinery in this scheme, a generator can be installed on the tractor to supply power to this device.

[0067] Working process: First, lay the first waterproof blanket on the base layer. When laying the first waterproof blanket, you can use the existing manual laying method or use this device. When laying the first waterproof blanket using this device, it is not necessary to spread bentonite, that is, no bentonite is put into the material bin 2, the spreading component does not need to work, and the first feeding box 18 can be lifted upward (one end of the rope can be tied to the bottom of the second feeding box 17, and the other end can be tied to the material bin 2, so that the bottom of the first feeding box 18 is moved upward and held), so that it does not contact the base layer. The specific operation is as follows: The waterproof blanket roll to be laid is installed on the material rack 5. After the end of the waterproof blanket passes over the guide roller 4, it passes between the two conveyor rollers 6, then passes under the compaction component, and then contacts the base layer. The end is then fixed using existing conventional methods, such as using steel nails. After fixing, the traction machine drives the device to move in the laying direction. During the movement, the conveyor rollers 6 rotate, causing the waterproof blanket roll to unfold and be laid on the ground. During the laying process, the pressure roller 28 and the pressure plate 12 flatten the waterproof blanket. Meanwhile, during the process, the leveling component can further clean the base layer (the base layer is generally flat, but in actual construction, some debris such as soil and stones will inevitably remain on the base layer). This process continues until the first waterproof blanket is laid. After the first layer is laid, this waterproof blanket is the lower waterproof blanket 35 mentioned in this plan. Then, the adjacent waterproof blanket is laid as the upper waterproof blanket 34. When laying the upper waterproof blanket 34, because overlapping is involved, the first material box 18 needs to be restored to its original state, that is, the ropes need to be removed. The bottom of the first feeding hopper 18 can be pressed against the overlap of the lower waterproof blanket 35. Then, the upper waterproof blanket 34 is installed onto the material rack 5, and its ends are fixed in the same way as the first one. The edge of the upper waterproof blanket 34 needs to cover part of the edge of the lower waterproof blanket 35 (for overlap). A section of bentonite mixed with water is first spread manually (this section starts from the end and extends to the bottom outlet of the first feeding hopper 18). Bentonite is then fed into the material hopper 2, and water is also added to the water tank. The preparation work is complete. See the attached document for the current state. Figure 12Then, the process begins. During the process, the cleaning components clean the overlapping areas of the lower waterproof blanket 35. The spiral conveyor plate 29 rotates and pushes the bentonite to the discharge port 32, and then into the first discharge box 18 and the second discharge box 17. The bentonite mixes with water under the action of the corresponding water spraying components and then falls onto the overlapping area of ​​the lower waterproof blanket 35, so that there is bentonite present when the upper waterproof blanket 34 and the lower waterproof blanket 35 come into contact. When the upper waterproof blanket 34 and the lower waterproof blanket 35 come into contact, the upper waterproof blanket 34 can be vibrated and compacted under the combined action of the pressure plate 12 and the first vibrator 9, making the overlapping area between the upper waterproof blanket 34 and the lower waterproof blanket 35 more compact and reducing the risk of leakage. After the second waterproof blanket is laid, the above operation is repeated for the subsequent waterproof blanket laying.
