Description

Technical Field

[0001] This application relates to the field of dredging and reclamation engineering technology, and in particular to a sludge storage structure and its construction method applicable to dredging and reclamation engineering. Background Technology

[0002] Dredging and reclamation engineering refers to a water conservancy project that removes silt and sand accumulated in water bodies, ports, rivers, lakes, and other water areas, and expands the shoreline outward to increase the land area through engineering methods such as reclamation.

[0003] Dredging refers to underwater excavation work using mechanical equipment to achieve purposes such as flood control, navigation, water diversion, and fishery improvement, as well as to provide foundation treatment for navigation structures and improve navigation conditions in waterways.

[0004] Reclamation is an operation that uses dredgers to excavate soil from the seabed, and the resulting slurry, pumped by a mud pump, is transported through discharge pipes to designated locations for filling. In dredging and reclamation projects, sediment storage structures are crucial facilities for handling the dredged sediment. They temporarily store the sediment for later use in filling or other treatment.

[0005] Most silt storage structures use gravity or pressure pipelines to transport silt to trucks or transport ships. The moisture content of the silt in the storage structure needs to be controlled to prevent silt from clumping or solidifying in the pipeline, which could cause blockages. Summary of the Invention

[0006] To reduce the solidification of silt in silt storage structures, this application provides a silt storage structure and its construction method suitable for dredging and reclamation projects.

[0007] Firstly, this application provides a mud storage structure suitable for dredging and reclamation projects, employing the following technical solution: A sediment storage structure suitable for dredging and reclamation projects, including A mud storage tank, wherein a plurality of mud storage tanks for storing mud and sand are provided in the mud storage tanks, and mud inlet pipes are connected to the mud storage tanks; A water storage tank, which is connected to several mud storage tanks; A support spans across a mud storage tank, on which a stirring assembly for agitating the mud storage tank is slidably mounted. The stirring assembly includes several stirring shafts located within corresponding mud storage tanks, and spiral stirring blades are fixedly connected to the stirring shafts. The stirring blades are evenly distributed on the shaft body of the stirring shaft.

[0008] By adopting the above technical solution, the water storage tank can replenish the mud storage tank with water, reducing the solidification of mud and sand due to water evaporation in the mud storage tank, which would make it difficult to transport mud and sand through pipelines. At the same time, when the water storage tank replenishes water to the mud storage tank, it is not easy for the mud in the mud storage tank to receive water evenly. However, when the stirring shaft rotates, it can drive the spiral stirring blades to stir in the mud storage tank, thereby mixing water evenly into the mud and sand. At the same time, when the spiral stirring blades rotate, they can break up the solidified mud and sand, so that the mud and sand maintain a certain moisture content. Multiple storage tanks are installed in the mud storage tank, which allows the mud and sand in the mud storage tank to be evenly distributed in each tank. On the one hand, this improves the construction efficiency of the mixing components and reduces the possibility that excessive mud and sand in the storage tanks will put too much pressure on the mixing components, thus preventing the mixing components from operating normally. On the other hand, the setting of multiple storage tanks can make the moisture content of the mud and sand in the same storage tank similar, reducing the polarization caused by excessive time intervals between mud and sand transported by the mud inlet pipe, which would result in the mud and sand at the bottom of the storage tank solidifying while the mud and sand at the top of the storage tank has excessive moisture.

[0009] Preferably, the spiral stirring blades are provided with several perforations.

[0010] By adopting the above technical solution, the perforation design allows some of the mud and sand to pass through the perforations during the mixing process, thereby further breaking up the mud and sand lumps and improving the mixing effect.

[0011] Preferably, a sliding block is slidably disposed on the support, a cylinder is fixedly connected to the bottom of the sliding block, a drive rod is fixedly connected to the output end of the cylinder, and a drive assembly for driving the stirring shaft to rotate is disposed inside the drive rod.

[0012] By adopting the above technical solution, the stirring component is slidably mounted on the support, allowing the stirring component to move along the length of the mud storage tank. The cylinder enables the stirring component to move in the opposite direction vertically within the mud storage tank, thereby allowing the stirring component to stir the mud and sand in the mud storage tank in all directions, improving the uniformity of mud and sand mixing and ensuring the moisture content of the mud and sand.

[0013] Preferably, the drive assembly includes a drive source fixed inside the drive rod and a first rotating rod fixedly connected to the output end of the drive source. A drive gear is fixedly connected to the end of the first rotating rod away from the drive source, and a driven gear meshes with the drive gear. A second rotating rod is rotatably disposed inside the drive rod, and the driven gear is sleeved and fixedly connected to the end of the second rotating rod. The end of the second rotating rod away from the driven gear is fixedly connected to the stirring shaft.

[0014] By adopting the above technical solution, when the drive source drives the first rotating rod to rotate, the driving gear drives the driven gear to rotate, thereby causing the second rotating rod to drive the stirring shaft to rotate, thus causing the stirring assembly to stir the mud and sand.

[0015] Preferably, the bottom of the mud storage tank is provided with several water outlet channels, and the bottom plate of the mud storage tank is a permeable plate.

[0016] By adopting the above technical solution, since the mud and sand fed into the mud storage tank through the mud inlet pipe have a high moisture content, the moisture in the mud and sand will seep to the bottom of the mud storage tank and flow through the permeable plate into the water storage tank, thereby reducing the moisture content in the mud and sand.

[0017] Preferably, the end of the water outlet tank is connected to a water outlet pipe, and the other end of the water outlet pipe is connected to a water storage tank and supplies water to the water storage tank.

[0018] By adopting the above technical solution, one end of the outlet pipe is connected to the outlet tank. Water in the storage tank flows into the outlet pipe and is pumped into the storage tank, thereby supplying water to the storage tank. This allows for the recycling of water in the sediment, maximizing resource utilization.

[0019] Preferably, a cleaning component for cleaning the mud storage tank is slidably disposed on the support. The cleaning component includes a cleaning plate slidably disposed on the support, and the two ends of the cleaning plate are in contact with the two sides of the mud storage tank.

[0020] By adopting the above technical solution, after the mud and sand in the mud storage tank are emptied, some mud and sand blocks will adhere to the inner wall of the mud storage tank. When the cleaning plate slides on the support, it can scrape off the mud and sand blocks on both sides of the inner wall of the mud storage tank, thereby increasing the volume of the mud storage tank when it is empty, which makes it easier to fill more sand and soil in the future.

[0021] Preferably, several scrapers are connected to both sides of the cleaning plate, and the scrapers on the same side of the cleaning plate are spaced apart. The bracket can be extended and retracted vertically.

[0022] By adopting the above technical solution, the scraper on the cleaning plate can clean the other two inner walls of the mud storage tank. When the scraper abuts against the inner wall of the mud storage tank, the scraper can move up and down in the mud storage tank when the support is extended and retracted, thereby cleaning the other two inner walls of the mud storage tank and improving the cleanliness of the mud storage tank.

[0023] Secondly, this application provides a method for constructing a silt storage structure applicable to dredging and reclamation projects, comprising the following steps: S1. Excavate mud storage tank and water storage tank, excavate several water outlet tanks on the bottom wall of mud storage tank, and connect the water outlet pipes to the water storage tanks. Lay a waterproof layer on the inner wall of mud storage tank, water storage tank and water outlet tank. S2. Hoist the mud storage tank into the mud storage trough and fix it in place. Install the bracket and install the stirring and cleaning components on the bracket. S3. When the moisture content of the mud and sand in the mud storage tank is lower than the requirement, the water storage tank supplies water to the mud storage tank, and the stirring component stirs the mud and sand, breaking up the solidified mud and sand blocks and mixing them evenly. S4. After the mud and sand in the mud storage tank are discharged through the pipe, the cleaning plate slides on the support to scrape off the mud and sand on the inner wall of the mud storage tank. The support extends and retracts vertically to further expand the cleaning range of the inner wall of the mud storage tank, thereby scraping off and discharging the mud and sand blocks on the inner wall of the mud storage tank.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. When the stirring shaft rotates, it drives the spiral stirring blades to agitate within the mud storage tank, thus evenly mixing water into the mud and sand. Simultaneously, the rotating spiral stirring blades break up any solidified mud and sand, maintaining a certain moisture content. Multiple mud storage tanks within the mud storage trough ensure even distribution of mud and sand across them. This improves the efficiency of the mixing components, reducing the possibility of excessive pressure on the components due to excessive mud and sand in the tanks, which could cause malfunctions. Furthermore, the multiple tanks ensure that the moisture content of the mud and sand within the same tank is similar, reducing the potential for uneven distribution—where mud and sand at the bottom of the tank solidifies while at the top has excessive moisture—caused by long intervals between mud and sand transported from the inlet pipe. 2. One end of the outlet pipe is connected to the outlet tank. Water in the storage tank flows into the outlet pipe and is pumped into the storage tank, thereby supplying water to the storage tank and recycling the water in the sediment to maximize resource utilization. 3. After the mud and sand in the mud storage tank are emptied, some mud and sand chunks will adhere to the inner wall of the mud storage tank. When the cleaning plate slides on the support, it can scrape off the mud and sand chunks on both sides of the inner wall of the mud storage tank, thereby increasing the volume of the mud storage tank when it is empty, making it easier to fill more sand and soil later.

[0026] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0027] This application discloses a mud storage structure and its construction method applicable to dredging and reclamation projects.

[0028] A mud storage structure suitable for dredging and reclamation projects, referring to Figure 1 and Figure 2 The system includes a mud storage tank 1 and a water storage tank 2 located on one side of the mud storage tank 1. Several water outlet tanks 11 are provided on the bottom wall of the mud storage tank 1. The end of the water outlet tank 11 is connected to a water outlet pipe 12. A booster pump is installed on the water outlet pipe 12. The other end of the water outlet pipe 12 is connected to the water storage tank 2. The inner walls of the water storage tank 2, the mud storage tank 1 and the water outlet tank 11 are all covered with a waterproof layer to reduce the situation of water seeping into the ground and causing water waste.

[0029] Reference Figure 1 Several mud storage tanks 3 are fixed in the mud storage tank 1. A water supply pipe 32 connects the mud storage tanks 3 and the water storage tank 2. The bottom wall of the mud storage tank 3 is a permeable plate, and a mud inlet pipe 31 is connected to the mud storage tank 3. When the mud inlet pipe 31 transports mud into the mud storage tank 3, the mud at this time has a high water content because it has just been dredged from the river. After the mud enters the mud storage tank 3, the water flows into the outlet tank 11 through the permeable plate. The water in the outlet tank 11 flows into the outlet pipe 12 and is transported to the water storage tank 2 by a booster pump to replenish the water in the water storage tank 2. This facilitates the supply of water to the water storage tank when the mud in the water storage tank is solidified, and realizes the recycling of water resources.

[0030] Reference Figure 1 and Figure 2The top of the mud storage tank 1 is provided with a support 4 that spans several mud storage tanks 3. Two supports 4 are arranged in parallel. A stirring component 5 for mixing the mud and sand in the mud storage tanks 3 is slidably arranged on the support 4. The stirring component 5 includes a stirring shaft 51 that is rotatably arranged in the mud storage tanks 3. A threaded stirring blade 52 is fixedly connected to the stirring shaft 51. Several through holes 53 are opened on the threaded stirring blade 52.

[0031] When the sediment solidifies, the water storage tank 2 supplies water to the sediment storage tank 3. Since the water is not easily distributed evenly in the sediment, the stirring shaft 51 rotates. This rotation drives the spiral stirring blades, which in turn agitate the sediment in the sediment storage tank 3, breaking up the solidified sediment and ensuring that it is evenly moistened. As the spiral stirring blades rotate, some sediment passes through the perforations 53, further refining the sediment clumps and increasing its moisture content. This makes the sediment less prone to solidification and facilitates its transport through the pipeline.

[0032] join Figure 2 and Figure 3 A sliding block 54 is slidably mounted on the bracket 4. A cylinder 55 is fixedly connected to the bottom of the sliding block 54. An L-shaped drive rod 56 is fixedly connected to the output end of the cylinder 55. A through groove 561 is opened inside the drive rod 56. A drive assembly 6 for driving the rotating shaft to rotate is arranged in the inner wall of the through groove 561. The drive assembly 6 includes a drive source 61 fixedly mounted on the inner wall of the through groove 561. A first rotating rod 62 is fixedly connected to the output end of the drive source 61. A drive gear 64 is fixedly connected to the end of the first rotating rod 62. A second rotating rod 63 is rotatably mounted in the through groove 561. The second rotating rod 63 is perpendicular to the first rotating rod 62. A driven gear 65 that meshes with the drive gear 64 is fixedly connected to the end of the second rotating rod 63. The end of the second rotating rod 63 away from the driven gear 65 passes through the through groove 561 and is fixedly connected to the rotating shaft.

[0033] When the drive source 61 drives the first rotating rod 62 to rotate, the driving gear 64 drives the driven gear 65 to rotate, which in turn causes the second rotating rod 63 to drive the stirring shaft 51 to rotate, thereby causing the stirring assembly 5 to stir the mud and sand. When the output end of the cylinder 55 extends or retracts, the stirring assembly 5 can move vertically in the mud storage tank 3. When the sliding block 54 slides on the bracket 4, the stirring assembly 5 can move along the length of the mud storage tank 3. This allows the stirring assembly 5 to stir the mud and sand in the mud storage tank 3 in all directions, improving the uniformity of mud and sand mixing and ensuring the moisture content of the mud and sand.

[0034] Reference Figure 4 and Figure 5The bracket 4 includes a vertically arranged telescopic rod 41 and a guide rail 42 located between two telescopic rods 41. A cleaning component 7 is slidably arranged on the bracket 4. The cleaning component 7 includes several moving blocks 71 slidably arranged on the guide rail 42. A cleaning plate 72 is fixedly connected to the bottom of the moving block 71. Several scrapers 73 are fixedly connected to the two sides of the cleaning plate 72. Several scrapers 73 on the same side of the cleaning plate 72 are spaced apart.

[0035] After the mud and sand in the mud storage tank 3 are transported out, some mud and sand chunks will adhere to the inner wall of the mud storage tank 3. The moving block 71 drives several cleaning plates 72 to move above the corresponding mud storage tank 3. The telescopic rod 41 shortens, so that the cleaning plates 72 are located inside the mud storage tank 3. The moving block 71 moves back and forth on the guide rail 42, so that the cleaning plates 72 scrape the mud and sand off the two side walls of the mud storage tank 3. Then the moving block 71 moves until the scraper 73 is pressed against the inner wall of the end of the mud storage tank 3. The telescopic rod 41 extends and retracts back and forth, so that the scraper 73 cleans the inner wall of the end of the mud storage tank 3. The cleaning component 7 can scrape the mud and sand off the inner wall of the mud storage tank 3, thereby increasing the volume of the mud storage tank 3 when it is empty, making it easier to fill more sand and soil later.

[0036] The implementation principle of a sludge storage structure applicable to dredging and reclamation projects according to an embodiment of this application is as follows: When sludge and sand become solidified, the water storage tank 2 supplies water to the sludge storage tank 3. Since the water is not easily evenly distributed in the sludge and sand, the drive source 61 drives the stirring shaft 51 to rotate. When the stirring shaft 51 rotates, it drives the spiral stirring blades to rotate, thereby agitating the sludge and sand in the sludge storage tank 3 and breaking up the solidified sludge and sand, ensuring that the sludge and sand are evenly moistened. As the spiral stirring blades rotate, some sludge and sand will pass through the perforations 53, further refining the sludge and sand blocks, increasing the water content in the sludge and sand, making it less prone to solidification, and facilitating the transportation of the sludge and sand in the pipeline.

[0037] After the mud and sand in the mud storage tank 3 are transported out, the telescopic rod 41 shortens, so that the cleaning plate 72 is located inside the mud storage tank 3. The moving block 71 moves back and forth on the guide rail 42, so that the cleaning plate 72 scrapes the mud and sand on the two side walls of the mud storage tank 3 clean. Then the moving block 71 moves until the scraper 73 is pressed against the inner wall of the end of the mud storage tank 3. The telescopic rod 41 extends and retracts back and forth, so that the scraper 73 cleans the inner wall of the end of the mud storage tank 3.

[0038] This application also discloses a method for constructing a silt storage structure applicable to dredging and reclamation projects, comprising the following steps: S1. Excavate mud storage tank 1 and water storage tank 2, excavate several water outlet tanks 11 on the bottom wall of mud storage tank 1, and connect the two ends of water outlet pipe 12 to water storage tank 2 and water storage tank 2 respectively, and lay a waterproof layer on the inner wall of mud storage tank 1, water storage tank 2 and water outlet tank 11. S2. Hoist the mud storage tank 3 into the mud storage trough 1 and fix it, install the bracket 4 and install the stirring component 5 and the cleaning component 7 on the bracket 4; S3. When the moisture content of the mud and sand in the mud storage tank 3 is lower than the requirement, the water storage tank 2 supplies water to the mud storage tank 3, the drive source 61 drives the stirring shaft 51 to rotate, and the stirring shaft 51 rotates, which drives the spiral stirring blades to rotate, thereby turning the mud and sand in the mud storage tank 3. The moving block 71 slides back and forth on the support 4, and the output end of the cylinder 55 continuously extends and retracts, breaking up the solidified mud and sand blocks and mixing them evenly. S4. After the mud and sand in the mud storage tank 3 are discharged through the pipe, the cleaning plate 72 slides on the bracket 4 to scrape off the mud and sand on the inner wall of the mud storage tank 3. When the scraper 73 comes into contact with the inner wall of the mud storage tank 3, the telescopic rod 41 extends vertically, thereby further expanding the cleaning range of the inner wall of the mud storage tank 3, and then scraping off and discharging the mud and sand blocks on the inner wall of the mud storage tank 3.

Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
