When planning the basic excavation construction, minimizing the amount of earthwork transported in and out not only affects the earthwork cost, but also has a great impact on the on-site layout.

[0036] Now, the river channel earthwork balance construction method and device provided by the present invention will be described.

[0037] As Figure 1 shown, the first embodiment of the present invention provides a river channel earthwork balance construction method, including the following steps:

[0038] S100. According to the difference between the current situation of the river channel and the designed cross-section of the river channel excavation, calculate the designed cross-section of the river embankment when the available earthwork in the earthwork to be excavated in the river channel is paved on the river embankment.

[0039] S200. Excavate the river channel according to the designed cross-section of the river channel excavation, and process the excavated earthwork to obtain available earthwork.

[0040] S300. Add functional materials to the available earthwork and pave it on the river embankment.

[0041] Compared with the prior art, the river channel earthwork balance construction method provided in this embodiment can achieve the earthwork balance of river channel construction and greatly reduce the transportation and storage costs of earthwork by excavating the earthwork in the river channel, processing it, adding functional materials, and then directly paving it on the river embankment for utilization.

[0042] As Figure 1 shown, a specific implementation manner provided by the present invention on the basis of the first embodiment is as follows:

[0043] S100. According to the difference between the current situation of the river channel and the designed cross-section of the river channel excavation, calculate the designed cross-section of the river embankment when the available earthwork in the earthwork to be excavated in the river channel is paved on the river embankment.

[0044] Specifically, it includes:

[0045] S110. On the entire length of the river channel to be treated, calculate the total amount of earthwork to be excavated in the river channel according to the difference between the current situation of the river channel and the designed cross-section of the river channel excavation.

[0046] S120. Estimate the remaining stock of available earthwork after treating the earthwork to be excavated in the river channel, and estimate the admixture amount of functional materials when using the earthwork as embankment materials. Determine the total amount of embankment materials according to the remaining stock and the admixture amount.

[0047] S130. Calculate the designed cross-section of the river embankment according to the total amount of embankment materials, so that the available earthwork excavated from the river channel can be stably paved on the river embankment.

[0048] S200. Excavate the river channel according to the designed cross-section of the river channel excavation, and process the excavated earthwork to obtain available earthwork.

[0049] Specifically, plan a storage area on the river embankment. After picking out sundries such as large stones, trees, and large pieces of garbage from the excavated earthwork, store them in the storage area, remove the excess moisture until the moisture content of the earthwork is within a preset range to become available earthwork. The excavation of the earthwork can use equipment such as a cutter suction dredger or an excavator according to the specific situation of the river channel.

[0050] S300. Add functional materials to the available earthwork and pave it on the river embankment.

[0051] Specifically, the available earthwork in the stockpiling area is spread layer by layer onto the river embankment, and functional materials are added and compacted flat on each layer until the shape of the river embankment conforms to the designed cross-section; the functional materials include one or more of quicklime, cement, fly ash, and sand and gravel aggregates, and preferably quicklime is used. Quicklime can absorb the moisture in the earthwork, play a solidifying role, and can also play a role in sterilizing and insecticidal, which is beneficial to reducing the possibility of the river embankment rotting and deforming due to biological erosion and maintaining the stability of the river embankment.

[0052] 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 the earthwork on each layer.

[0053] Specifically, as Figures 2 to 5 shown, the lime powder refining device includes a first refining layer, a plurality of guiding channels 24, and a second refining layer. The first refining layer has an upper filter plate 13, a rotating shaft 9, and grinding blocks 18. The rotating shaft 9 is rotatably arranged on the upper filter plate 13, and the grinding blocks 18 are connected to the rotating shaft 9. The grinding blocks 18 are used for extruding and rotatingly grinding the lime on the upper filter plate 13; the plurality of guiding channels 24 are uniformly arranged in the circumferential direction, and the guiding channels 24 are provided with a material receiving port and a material discharging 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. The grinding sleeve 4 is sleeved 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 elastic pieces 26, and a lower support ring 6. One end of the elastic piece 26 is connected to the upper support ring 23, and the other end of the elastic piece 26 is connected to the lower support ring 6. The plurality of elastic pieces 26 are uniformly arranged in the circumferential direction. A baffle 27 is arranged on each side of each elastic piece 26. A powder grinding channel is formed between the elastic piece 26, the two baffles 27, and the inner wall of the grinding sleeve 4. The upper ends of the plurality of powder grinding channels are connected to the material discharging ports in one-to-one correspondence. The elastic piece 26 is arc-shaped, and the grinding sleeve 4 is used for rotatingly grinding the lime powder between its arc top and the elastic piece 26.

[0054] By setting a first refinement layer, the upper filter plate 13 and the grinding block 18 are provided in the first refinement layer. The lime powder with different specifications after preliminary crushing 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 number of guiding channels 24 are evenly arranged along the circumferential direction at the lower end of the upper filter plate 13. The fine particles after grinding flow into the guiding channels 24 through the upper filter plate 13. At the same time, the present invention also adds a second refinement layer to further refine the fine particles. The second refinement 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 number of elastic pieces 26 and a lower support ring 6. One end of the elastic piece 26 is connected to the upper support ring 23, and the other end of the elastic piece 26 is connected to the lower support ring 6. The number of elastic pieces 26 is evenly arranged along the circumferential direction. A baffle 27 is arranged on each side of each elastic piece 26. A powder grinding channel is formed between the elastic piece 26, the two baffles 27 and the inner wall of the grinding sleeve 4. When installing, the elastic component is reasonably squeezed to make the elastic piece 26 of the elastic component generate an elastic deformation of outward arc protrusion, so as to control the gap and extrusion force between the arc top of the elastic piece 26 and the inner wall of the grinding sleeve 4. The fine lime powder enters the powder grinding channel from the guiding channel 24 and then falls at the arc top of the elastic piece 26. When the grinding sleeve 4 rotates, it will perform secondary grinding on the lime powder at the arc top of the elastic piece 26. When the lime powder is ground to be able to pass through the gap between the elastic piece 26 and the inner wall of the grinding sleeve 4, the lime powder flows out from the powder grinding channel. Through the structural design, the present invention refines and processes lime blocks of different sizes, making the lime powder more delicate and enabling the lime to be added to the earthwork more evenly.

[0055] 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 powder grinding channels as there are elastic pieces 26. Setting a plurality of powder grinding channels can improve the powder grinding efficiency.

[0056] In this embodiment, the elastic component can ensure the elasticity through material selection and processing and will not be deformed due to the extrusion of lime powder during grinding.

[0057] As Figure 5 shown, a specific implementation manner provided by the present invention on the basis of the first implementation manner is as follows. The elastic component further 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.

[0058] In this embodiment, a support column 28 is added to ensure the stability and rigidity of the entire elastic component. When installing the elastic component, since 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 distorted. When the lower support ring 6 is slightly moved upward toward the upper support ring 23 by extrusion, only the elastic piece 26 will produce an arc-shaped outward elastic deformation. At the same time, adding the support column 28 can increase the rigidity of the entire elastic component, and the elastic piece 26 is less likely to be deformed by the extrusion of lime powder, and can cooperate better with the grinding sleeve 4 to finely grind the lime powder for the second time.

[0059] As Figures 4 to 5 shown, on the basis of the above embodiment, the present invention further provides a specific embodiment as follows. The lower support ring 6 protrudes from the lower end of the support column 28. The lower support ring 6 is provided with a plurality of slots 29, and the number of slots 29 is the same as that of the baffles 27. The lower ends of the baffles 27 are inserted into the slots 29. A pressing plate 7 is provided at the lower end of the lower support ring 6, and the pressing plate 7 is connected to a pushing member. The pushing 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 elastic piece 26 and the inner wall of the grinding sleeve 4.

[0060] In this embodiment, the pushing member can be a cylinder 8 or an electric rod. The pushing member can push the lower support ring 6 to move slightly along the axis direction of the support column 28 through the pressing plate 7. By controlling the moving displacement of the lower support ring 6 through the pushing member, the elastic deformation degree of the elastic piece 26 can be controlled, and further the size of the small gap between the arc top of the elastic piece 26 and the grinding sleeve 4 can be controlled. Through this small gap, the screening specification of the lime powder can be controlled.

[0061] At the same time, the lower support ring 6 protrudes from the lower end of the support column 28. The lower support ring 6 is provided with a plurality of slots 29, and the number of slots 29 is the same as that of the baffles 27. The lower ends of the baffles 27 are inserted into the slots 29. When the pushing member pushes the lower support ring 6 to move upward toward the upper support ring 23, the baffles 27 are inserted deeper into the slots 29. Through the structural design, neither the support column 28 nor the baffle 27 will hinder the movement of the lower support ring 6, which is more convenient for adjusting the deformation of the elastic piece 26.

[0062] As Figures 4 to 5 shown, on the basis of the above embodiment, the present invention further provides a specific embodiment as follows. A plurality of powder crushing rods 25 are provided on the upper part of the elastic piece 26.

[0063] In this embodiment, a plurality of powder crushing rods 25 are arranged on the upper part of the elastic piece 26. The lime powder falling from the guiding channel 24 into the grinding channel will generate a certain speed during the falling process. If the lime powder impacts the powder crushing rods 25, it can be further broken. Therefore, the more and denser the powder crushing rods are arranged, the better.

[0064] As Figure 2 and Figure 4As shown in the figure, a specific embodiment provided by the present invention on the basis of the above embodiments is as follows. The second refinement layer further includes a lower filter plate 5, which is an arc-shaped plate. The lower filter plate 5 is sleeved outside the lower support ring 6, and the lower end of the powder grinding channel is connected to the lower filter plate 5.

[0065] In this embodiment, adding the lower filter plate 5 can further ensure the powder output specifications.

[0066] As Figure 3 shown in the figure, a specific embodiment provided by the present invention on the basis of the above embodiments is as follows. The filter holes on the upper filter plate 13 are distributed along the circumferential direction to form an annular filter surface. An inner edge plate 16 is arranged on the inner ring of the filter surface, and an outer edge plate 11 is arranged on the outer ring of the filter surface. The grinding block 18 is located between the inner edge plate 16 and the outer edge plate 11.

[0067] In this embodiment, the annular filter surface, and the annular inner edge plate 16 and the outer edge plate form an annular powder grinding space. When the rotating shaft 9 rotates, the grinding block 18 slides along the annular powder grinding space to grind the lime powder.

[0068] As Figure 3 shown in the figure, a specific embodiment provided by the present invention on the basis of the above embodiments is as follows. A partition plate 12 is arranged on the upper filter plate 13. The partition plate 12 is arranged between the inner edge plate 16 and the outer edge plate 11, and the partition plate 12 is used to collide with the grinding block 18 to crush and refine the lime powder.

[0069] In this embodiment, when the grinding block 18 rotates for grinding, some lime powder with larger particle sizes cannot enter the bottom surface of the grinding block 18 for grinding, but is pushed on the side surface of the grinding block 18. By setting the partition plate 12, when the grinding block 18 rotates to the partition plate 12, it will hit the partition plate 12, thereby crushing the larger particle powder on the side surface of the grinding block 18, realizing the refinement of particles and improving the refinement rate.

[0070] As Figure 3 shown in the figure, a specific embodiment provided by the present invention on the basis of the above embodiments is as follows. Multiple partition plates 12 can be provided. The multiple partition plates 12 divide the space between the inner edge plate 16 and the outer edge plate 11 into multiple refinement chambers, and one grinding block 18 is arranged in each refinement chamber.

[0071] In this embodiment, setting multiple partition plates 12 and grinding blocks 18 can improve the grinding and refinement efficiency. At the same time, when the rotating shaft 9 rotates forward and backward repeatedly, the multiple grinding blocks 18 respectively impact the partition plates 12 on both sides repeatedly. Thus, on the one hand, the grinding block 18 can grind the smaller powder below it, and at the same time, it can also impact and break the larger powder on both sides to achieve efficient refinement.

[0072] As Figure 3As shown in the figure, the present invention further provides a specific embodiment on the basis of the above-mentioned embodiment as follows. A first plug 17 is provided on the rotating shaft 9. The first refinement layer further includes a lower connecting sleeve 15, an upper connecting sleeve 10, a first support rod 19, a second support rod 20, and a pulling and pushing member. The lower connecting sleeve 15 is rotatably arranged in the middle of the upper filter plate 13, and a first socket 14 is provided 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. The rotating shaft 9 passes through the upper connecting sleeve 10 and the lower connecting sleeve 15 and can move along its own axis. The first plug 17 is inserted into the first socket 14; 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. The other end of the second support rod 20 is rotatably connected to the middle of the first support rod 19; the pulling and pushing member is connected to the rotating shaft 9 and is used to drive the rotating shaft 9 to move.

[0073] In this embodiment, the grinding block 18 can be lifted through the structural design. The upper connecting sleeve 10 and the lower connecting sleeve 15 are spaced apart in the first refinement layer, 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, 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, the first plug 17 is inserted into the first socket 14, and the rotating shaft 9 can move up and down along its own axis under the drive of the pulling and pushing member. During the up and down movement of the rotating shaft 9, the first plug 17 is always inserted into the first socket 14. Thus, the rotation of the rotating shaft 9 can drive the upper connecting sleeve 10 and the lower connecting sleeve 15 to rotate synchronously.

[0074] The grinding block 18 is located between the inner edge plate 16 and the outer edge plate.
