[0023] The river channel earthwork balancing construction method and device provided by the present invention are now described.

[0024] like Figure 1 As shown, the first embodiment of the present invention provides a river channel earthwork balancing construction method, comprising the following steps: S100.

[0025] Compared with the prior art, the river channel earthwork balance construction method provided in this embodiment can achieve earthwork balance in river channel construction by excavating earthwork in the river channel, processing it, adding functional materials, and then paving it on the riverbank for direct use, thereby greatly reducing the transportation and storage costs of earthwork.

[0026] like Figure 1 As shown, a specific implementation mode provided by the present invention based on the first implementation mode is as follows: S100. Based on the difference between the current status of the river channel and the designed cross section of the river channel excavation, calculate the designed cross section of the river bank when the available earthwork to be excavated in the river channel is laid on the river bank; Specifically, it includes: S110. Calculate the total earthwork volume to be excavated in the river channel over the entire length of the river channel to be regulated based on the difference between the current status of the river channel and the designed section for river channel excavation; S120, estimating the remaining usable earth after processing the earth that needs to be excavated in the river channel, and estimating the amount of functional materials added when the earth is used as river embankment material, and determining the total amount of embankment materials based on the remaining amount and the amount of functional materials added; S130. Calculate the design section of the river bank based on the total amount of embankment materials so that the usable earth excavated from the river channel can be stably laid on the river bank.

[0027] S200, excavating the river channel according to the designed section of river channel excavation, and processing the excavated earth to obtain usable earth; Specifically, a storage area is planned on the river bank, and large rocks, trees, large pieces of garbage and other debris are picked out from the excavated earth and stored in the storage area to remove excess water until the water content of the earth is within a preset range, making it usable earth. The excavation of the earth can be carried out using equipment such as suction dredgers or excavators according to the specific conditions of the river channel.

[0028] S300, adding functional materials to the available earthwork and laying them on the riverbank; Specifically, the available earth in the stockpile area is spread onto the river bank layer by layer, and functional materials are added to each layer and rolled flat until the shape of the river bank meets the designed section; the functional materials include one or more of quicklime, cement, fly ash, and sand and gravel aggregates, among which quicklime is preferably used. Quicklime can absorb moisture in the earth and play a solidifying role, and can also play a role in sterilization and insecticide, which is beneficial to reduce the possibility of the river bank becoming smelly and deformed due to biological erosion, and can maintain the stability of the river bank.

[0029] In some specific embodiments, the functional material is quicklime, and the functional material is crushed and refined by a lime refining mechanism. The lime refining mechanism is mounted on a construction vehicle through a mounting bracket, and the crushed and refined functional material is added to each layer of earth.

[0030] Specifically, Figures 2 to 5 As shown, the lime powder refining device includes a first refining layer, a plurality of guide channels 24, and a second refining layer. The first refining layer has an upper filter plate 13, a rotating shaft 9, and a grinding block 18. The rotating shaft 9 is rotatably arranged on the upper filter plate 13, and the grinding block 18 is connected to the rotating shaft 9. The grinding block 18 is used to squeeze and rotate and grind the lime on the upper filter plate 13; a plurality of guide channels 24 are evenly arranged along the circumferential direction, and the guide channels 24 are provided with a material receiving port and a material discharge port, and the material receiving port is connected to the upper filter plate 13; the second refining layer is located below the first refining layer, and the second refining layer has an elastic component and a grinding sleeve 4, and the grinding sleeve 4 is sleeved The elastic component is outside the elastic component and has the freedom to rotate around its own axis. The elastic component has an upper support ring 23, a plurality of spring pieces 26 and a lower support ring 6. One end of the spring piece 26 is connected to the upper support ring 23, and the other end of the spring piece 26 is connected to the lower support ring 6. The plurality of spring pieces 26 are evenly arranged along the circumferential direction. A baffle 27 is arranged on both sides of each spring piece 26. A grinding channel is formed between the spring piece 26, the two baffles 27 and the inner wall of the grinding sleeve 4. The upper ends of the plurality of grinding channels are connected to the discharge port one by one. The spring piece 26 is arc-shaped, and the grinding sleeve 4 is used to rotate and grind the lime powder between it and the arc top of the spring piece 26.

[0031] By setting the first refining layer, the first refining layer is provided with an upper filter plate 13 and a grinding block 18. After preliminary crushing, lime powder of different specifications is placed on the upper filter plate 13. The grinding block 18 is connected to the rotating shaft 9 and can rotate with the rotating shaft 9. When the rotating shaft 9 rotates, the grinding block 18 will squeeze and grind the larger particles on the upper filter plate 13. A plurality of guide channels 24 are evenly arranged along the circumferential direction at the lower end of the upper filter plate 13, and the fine particles after grinding flow into the guide channels 24 through the upper filter plate 13. At the same time, the present invention also adds a second refining layer to further refine the fine particles. The second refining layer is provided with an elastic component and a grinding sleeve 4. The grinding sleeve 4 is sleeved outside the elastic component and has the freedom to rotate around its own axis. The elastic component includes an upper support ring 23, a plurality of spring pieces 26 and a lower support ring 6. One end of the spring piece 26 is connected to the upper support ring 23, and the other end of the spring piece 26 is connected to the lower support ring 6. The plurality of spring pieces 26 are evenly arranged along the circumferential direction. A baffle 27 is arranged on both sides of each spring piece 26. A grinding channel is formed between the spring piece 26, the two baffles 27 and the inner wall of the grinding sleeve 4. When installing, the elastic component is reasonably squeezed and installed, so that the spring piece 26 of the elastic component produces an elastic deformation that bulges outward in an arc shape, thereby controlling the gap and squeezing force between the arc top of the spring piece 26 and the inner wall of the grinding sleeve 4. After the fine lime powder enters the grinding channel from the guide channel 24, it falls into the arc top of the spring piece 26. When the grinding sleeve 4 rotates, the lime powder at the arc top of the spring piece 26 will be ground twice. When the lime powder is ground to the gap between the spring piece 26 and the inner wall of the grinding sleeve 4, the lime powder flows out from the grinding channel. The invention refines lime blocks of different sizes through structural design, so that the lime powder is finer and the lime can be added into the earthwork more evenly.

[0032] In this embodiment, the rotating shaft 9 can be connected to the driving motor 1, and the driving motor 1 drives the rotating shaft 9 to rotate to quickly grind the lime powder on the upper filter plate 13. In this embodiment, there are as many grinding channels as there are spring pieces 26, and providing multiple grinding channels can improve the grinding efficiency.

[0033] In this embodiment, the elastic component can ensure elasticity through material selection and processing, and will not be deformed due to the extrusion of lime powder during grinding.

[0034] like Figure 5 As shown, the present invention provides a specific embodiment based on the first embodiment as follows: the elastic component also includes a support column 28, the upper end of the support column 28 is connected to the upper filter plate 13, and the upper support ring 23 and the lower support ring 6 are sleeved on the support column 28.

[0035] In this embodiment, a support column 28 is added to ensure the stability and rigidity of the entire elastic component. When the elastic component is installed, because the upper support ring 23 and the lower support ring 6 are sleeved on the support column 28, the upper support ring 23 and the lower support ring 6 will not be twisted and deformed. When the lower support ring 6 is squeezed and slightly moved toward the upper support ring 23, only the spring piece 26 will produce an arc-shaped elastic deformation outward. At the same time, adding a support column 28 can increase the rigidity of the entire elastic component, and the spring piece 26 will not be deformed due to the squeezing of the lime powder, and can cooperate with the grinding sleeve 4 to better refine the lime powder for secondary grinding.

[0036] like Figures 4 to 5 As shown, the present invention provides a specific implementation mode based on the above implementation mode as follows: the lower support ring 6 protrudes from the lower end of the support column 28, and a plurality of slots 29 are provided on the lower support ring 6. The number of the slots 29 is the same as that of the baffle 27. The lower end of the baffle 27 is inserted into the slot 29. A pressure plate 7 is provided at the lower end of the lower support ring 6. The pressure plate 7 is connected to a push member, and the push member is used to push the lower support ring 6 to move along the support column 28 to adjust the gap between the arc top of the spring piece 26 and the inner wall of the grinding sleeve 4.

[0037] In this embodiment, the push member can be a cylinder 8 or an electric lever. The push member can push the lower support ring 6 to move slightly along the axis direction of the support column 28 through the pressure plate 7. By controlling the displacement of the lower support ring 6 through the push member, the elastic deformation degree of the spring piece 26 can be controlled, and the size of the small gap between the arc top of the spring piece 26 and the grinding sleeve 4 can be further controlled. Through this small gap, the output specification of the lime powder can be controlled.

[0038] At the same time, the lower support ring 6 protrudes from the lower end of the support column 28, and a plurality of slots 29 are provided on the lower support ring 6. The number of slots 29 is the same as that of the baffle 27, and the lower end of the baffle 27 is inserted into the slot 29. When the push member pushes the lower support ring 6 to move toward the upper support ring 23, the baffle 27 is inserted deeper into the slot 29. Through the structural design, the support column 28 and the baffle 27 will not hinder the movement of the lower support ring 6, and the deformation adjustment of the spring 26 is more convenient.

[0039] like Figures 4 to 5 As shown, the present invention provides a specific implementation mode based on the above implementation mode as follows: a plurality of powder crushing rods 25 are arranged on the upper part of the spring piece 26 .

[0040] In this embodiment, a plurality of powder crushing rods 25 are arranged on the upper part of the spring piece 26. The lime powder falling from the guide channel 24 into the grinding channel will generate a certain speed during the falling process. If the lime powder hits the powder crushing rods 25, it can be further crushed. Therefore, the more and denser the powder crushing rods are arranged, the better.

[0041] like Figure 2 and Figure 4As shown, the present invention provides a specific implementation mode based on the above implementation mode as follows: the second refining layer also includes a lower filter plate 5, the lower filter plate 5 is an arc-shaped plate, the lower filter plate 5 is sleeved outside the lower support ring 6, and the lower end of the grinding channel is connected to the lower filter plate 5.

[0042] In this embodiment, the additional lower filter plate 5 can further ensure the powder output specifications.

[0043] like Figure 3 As shown, the present invention provides a specific embodiment based on the above embodiment as follows: the filter holes on the upper filter plate 13 are distributed along the circumferential direction to form an annular filter surface, the inner ring of the filter surface is provided with an inner edge plate 16, the outer ring of the filter surface is provided with an outer edge plate 11, and the grinding block 18 is located between the inner edge plate 16 and the outer edge plate 11.

[0044] In this embodiment, an annular grinding space is formed between the annular filtering surface, the annular inner edge plate 16 and the outer edge plate. When the rotating shaft 9 rotates, the grinding block 18 slides along the annular grinding space to grind the lime powder.

[0045] like Figure 3 As shown, the present invention provides a specific embodiment based on the above embodiment as follows: a partition plate 12 is arranged on the upper filter plate 13, and the partition plate 12 is arranged between the inner edge plate 16 and the outer edge plate 11. The partition plate 12 is used to collide with the grinding block 18 to crush and refine the lime powder.

[0046] In this embodiment, when the grinding block 18 is rotating and grinding, some lime powder with larger particle size cannot enter the bottom surface of the grinding block 18 for grinding, but is pushed on the side of the grinding block 18. A partition 12 is provided, and when the grinding block 18 rotates to the partition 12, it will hit the partition 12, thereby crushing the larger particle powder on the side of the grinding block 18, thereby achieving particle refinement and improving the refinement rate.

[0047] like Figure 3 As shown, the present invention provides a specific implementation mode based on the above implementation mode as follows: a plurality of partition plates 12 can be provided, and the plurality of partition plates 12 divide the space between the inner edge plate 16 and the outer edge plate 11 into a plurality of refinement cavities, and a grinding block 18 is provided in each refinement cavity.

[0048] In this embodiment, multiple baffles 12 and grinding blocks 18 are provided to improve the grinding and refining efficiency. At the same time, when the rotating shaft 9 repeatedly rotates forward and reverse, multiple grinding blocks 18 repeatedly impact the baffles 12 on both sides thereof. Thus, the grinding blocks 18 can grind the smaller powder on the lower side thereof, and can also impact and crush the larger powder on both sides, thereby achieving efficient refining.

[0049] like Figure 3As shown, a specific embodiment of the present invention is provided on the basis of the above-mentioned embodiment as follows: a first plug 17 is arranged on the rotating shaft 9, and the first refinement layer also includes a lower connecting sleeve 15, an upper connecting sleeve 10, a first support rod 19, a second support rod 20, and a pull top member; the lower connecting sleeve 15 is rotatably arranged in the middle of the upper filter plate 13, and a first socket 14 is arranged on the inner wall of the lower connecting sleeve 15; the upper connecting sleeve 10 is located above the lower connecting sleeve 15, the upper connecting sleeve 10 is connected to the lower connecting sleeve 15, and is spaced apart from the lower connecting sleeve 15, and the rotating shaft 9 is penetrated by the upper connecting sleeve 15. The first plug 17 is inserted in the first socket 14 and is able to move along its own axis in the connecting sleeve 10 and the lower connecting sleeve 15; one end of the first support rod 19 is rotatably connected to the upper connecting sleeve 10, and the other end of the first support rod 19 is rotatably connected to the grinding block 18; one end of the second support rod 20 is rotatably connected to the rotating shaft 9, and the rotation connection point of the second support rod 20 and the rotating shaft 9 is located between the upper connecting sleeve 10 and the lower connecting sleeve 15, and the other end of the second support rod 20 is rotatably connected to the middle part of the first support rod 19; the top pull piece is connected to the rotating shaft 9, and is used to drive the rotating shaft 9 to move.

[0050] In this embodiment, the grinding block 18 can be lifted by structural design. The first refinement layer is provided with an upper connecting sleeve 10 and a lower connecting sleeve 15 at intervals, and the upper connecting sleeve 10 and the lower connecting sleeve 15 are connected by a connecting rod 21. A first socket 14 is provided on the inner wall of the lower connecting sleeve 15, and a first plug 17 is provided on the outer wall of the rotating shaft 9. The rotating shaft 9 is inserted into the upper connecting sleeve 10 and the lower connecting sleeve 15, and the first plug 17 is inserted into the first socket 14. The rotating shaft 9 can move up and down along its own axis under the drive of the top puller, and during the up and down movement of the rotating shaft 9, the first plug 17 is always plugged into the first socket 14, so that the rotation of the rotating shaft 9 can drive the upper connecting sleeve 10 and the lower connecting sleeve 15 to rotate synchronously.

[0051] The grinding block 18 is located between the inner edge plate 16 and the outer edge plate. A connecting seat 22 is provided on the upper end surface of the grinding block 18. The connecting seat 22 is rotatably connected to one end of the first support rod 19, and the other end of the first support rod 19 is rotatably connected to the upper connecting sleeve 10. One end of the second support rod 20 is rotatably connected to the rotating shaft 9, and the rotation connection point between the second support rod 20 and the rotating shaft 9 is located between the upper connecting sleeve 10 and the lower connecting sleeve 15. When the rotating shaft 9 moves, it will drive the second support rod 20 to rotate, thereby pushing the first support rod 19 to rotate, and driving the grinding block 18 to be slightly lifted. On the one hand, when feeding the upward filter plate 13, the grinding block 18 can be slightly lifted first; when the feeding is completed, the rotating shaft 9 rotates to drive the grinding block 18 to the top of the feeding place, and then the rotating shaft 9 is controlled to move downward, and the grinding block 18 is pressed down onto the powder to be ground for grinding.
