Description

Technical Field

[0001] The invention belongs to the technical field of building material processing and preparation, and specifically relates to a method for preparing a high-performance grouting material for offshore wind power. Background Art

[0002] Grouting connection is a typical method for connecting offshore wind turbine support structures to pile foundations. Grouting is usually used between the external pipe and the internal pipe, requiring the grouting material to have high fluidity, pourability, and ultra-high early strength and final strength. In recent years, the rapid development of prefabricated buildings has driven the development of high-performance grouting materials.

[0003] Offshore wind power grouting materials are generally mixed evenly by grouting material mixing and stirring devices. The traditional grouting material mixing and stirring devices have the following main technical problems in the process of stirring grouting materials: a. The stirring rod of the mixing barrel only rotates in the horizontal direction. Since its stirring direction is relatively single, the mixing effect of the grouting material is poor; b. After the mixing and stirring is completed, a certain amount of grouting material will adhere to the inside of the mixing barrel. In order to prevent the grouting material adhering to the inside of the stirring device from drying, it is necessary to flush the inside of the stirring device in time after the mixing is completed. Generally, the flushing is mostly done by the staff holding a water pipe, which not only wastes time and physical strength, but is also more troublesome to operate.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] The embodiment of the present invention provides a method for preparing high-performance grouting material for offshore wind power, comprising the steps of adding concrete construction waste, defoamer, water reducer, steel slag powder, coagulant and water into a grouting material mixing and stirring device and stirring evenly to obtain high-performance grouting material for offshore wind power. In this embodiment, the concrete construction waste is composed of cement, mineral powder and / or fly ash particles; the defoamer is an organosilicon defoamer and / or a polyether defoamer; the water reducer is a polycarboxylic acid comb polymer; the steel slag powder contains magnesium oxide and calcium oxide, and the steel slag powder is ball-milled without high-temperature remelting; the coagulant is one of chloride salt and calcium formate or a mixture of the two. Among them, each portion of high-performance grouting material for offshore wind power is mixed according to the following weight ratio: 500-600 parts of concrete construction waste, 1-2 parts of defoamer, 5-15 parts of water reducer, 0.5-2 parts of steel slag powder, and 1-2 parts of coagulant. It should be noted that the chemical composition of steel slag powder contains magnesium oxide and calcium oxide. Granular steel slag is always completely banned in building materials. It is easy to expand and burst. Because the distribution of calcium oxide and magnesium oxide in steel slag is extremely uneven, and the content in some particles is extremely high, it will cause a large expansion in the later stage, destroying the structure of cement or concrete and causing bursting. However, in the process of grinding into powder, this problem is solved, so that calcium oxide and magnesium oxide are evenly distributed in steel slag powder, and its expansion in cement solves the problem of large shrinkage rate of sleeve grouting material itself, and can achieve the index requirement of self-drying shrinkage rate ≤ 0.045% without adding late expansion agent.

In this embodiment, the offshore wind power grouting material is added to the interior of the mixing barrel 1, and then the grouting material can be stirred by the stirring structure 3. The stirring structure 3 can realize multi-directional stirring of the offshore wind power grouting material, which can improve the mixing effect of the grouting material. When it is necessary to clean the inside of the mixing barrel 1, the connection structure 5 can be connected to the stirring structure 4, and then the stirring structure 3 will drive the cleaning structure 4 through the connection structure 5 to quickly and comprehensively clean the inside of the mixing barrel 1, which can avoid the need for the staff to hold the water pipe for flushing, effectively saving physical strength, shortening the cleaning time, and improving the convenience of the cleaning operation. The water can be filtered through the filtering structure 6, which can avoid clogging of the cleaning structure 4 and effectively improve the stability of use. After the grouting material is mixed and stirred, the limit of the unloading structure 7 can be quickly released through the limiting structure 8, and then the unloading work of the stirred grouting material can be realized through the unloading structure 7.

[0031] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the stirring structure 3 includes a connecting column 301 and a rotating drum 302. The connecting column 301 is fixedly connected to the connecting plate 2, the rotating drum 302 is rotatably connected to the connecting column 301, and three stirring rods 303 are rotatably connected to the rotating drum 302. One end of the stirring rod 303 is fixedly connected to a first bevel gear 304, and two second bevel gears 305 are fixedly connected to the connecting column 301. The three adjacent first bevel gears 304 are meshed with the same second bevel gear 305.

A first gear ring 310 is fixedly connected to the rotating drum 302. The center of the connecting column 301 and the center of the mixing barrel 1 are on the same straight line, and the three stirring rods 303 located around the same second bevel gear 305 are distributed in a circular array about the center of the second bevel gear 305.

[0032] Specifically in the present embodiment, when the grouting material needs to be mixed and stirred, the grouting material can be added to the interior of the mixing barrel 1, and then the motor 306 is started, and the output shaft of the motor 306 rotates to drive the first synchronous wheel 307 to rotate, and the first synchronous wheel 307 drives the second synchronous wheel 309 to rotate through the synchronous belt 308, and the rotation of the second synchronous wheel 309 will drive the rotating drum 302 to rotate, and the rotation of the rotating drum 302 will drive the multiple stirring rods 303 to rotate. Since the end of the stirring rod 303 is fixedly connected to the first bevel gear 304, and the first bevel gear 304 is meshed with the second bevel gear 305, when the stirring rod 303 rotates in the horizontal direction with the rotating drum 302, it itself will also rotate in the vertical direction. In this way, not only the grouting material can be stirred in the horizontal direction, but also the grouting material can be stirred in the vertical direction, so the stirring effect of the grouting material can be effectively improved.

[0033] See also Figures 1 to 9 As shown, the cleaning structure 4 specifically includes a support seat 401 and a water inlet pipe 402, the support seat 401 is fixedly connected to the connecting plate 2, the water inlet pipe 402 is fixedly connected to the support seat 401, the water inlet pipe 402 is provided with a filtering structure 6, two connecting pipes 403 are fixedly connected to the water inlet pipe 402, the two connecting pipes 403 are fixedly connected to the same top cover 404, two fixing blocks 405 are fixedly connected to the top cover 404, the fixing blocks 405 are fixedly connected to the connecting plate 2, a rotating sleeve 406 is rotatably connected to the top cover 404, two rotating pipes 407 are fixedly connected to the rotating sleeve 406, and a plurality of nozzles 408 are installed on the rotating pipe 407. The connecting pipe 403 is an L-shaped structure, the two rotating pipes 407 are distributed in a circular array about the middle of the rotating sleeve 406, and the plurality of nozzles 408 located on the same rotating pipe 407 are linearly and equidistantly distributed.

[0034] See also Figures 1 to 9 As shown, the connection structure 5 specifically includes a second gear ring 501 and a connection gear 502, the second gear ring 501 is fixedly connected to the rotating sleeve 406, the connection gear 502 is slidably connected to the second gear ring 501, the connection gear 502 is rotatably connected to the connecting sleeve 503, the connecting sleeve 503 is slidably connected to the sliding rod 504, the sliding rod 504 is slidably connected to the connecting plate 2, a retaining ring 505 is fixedly connected to the sliding rod 504, the outer sleeve of the sliding rod 504 is provided with a spring 506, one end of the spring 506 is fixedly connected to the retaining ring 505, and the other end of the spring 506 is fixedly connected to the connecting sleeve 503. A connecting cylinder 509 is fixedly connected to the connecting plate 2, and a limiting groove 510 is provided on the connecting cylinder 509, and a rotating ring 507 is rotatably connected to the sliding rod 504, and a limiting shaft 508 is fixedly connected to the rotating ring 507, and the limiting shaft 508 passes through the limiting groove 510 and is slidably connected to the connecting cylinder 509. The cross section of the top end of the slide bar 504 is a cylindrical structure, and the cross section of the bottom end of the slide bar 504 is a hexagonal structure.

[0035] Specifically in this embodiment, the external water delivery pipeline can be connected to the water inlet pipe 402. When the inside of the mixing barrel 1 needs to be cleaned, water can enter the inside of the water inlet pipe 402, and then the water will enter the inside of the two connecting pipes 403 from the water inlet pipe 402, and then enter the inside of the rotating sleeve 406, and then enter the inside of the two rotating pipes 407, and finally spray out from the multiple nozzles 408. During the process of water flowing inside the water inlet pipe 402, large particles of impurities in the water can be filtered through the filter net 602, thereby preventing large particles of impurities from clogging the nozzle 408. The stability of use is effectively improved. Next, by rotating and pushing the limit shaft 508, when the limit shaft 508 moves from the horizontal position at the top of the limit groove 510 to the vertical position on one side of the limit groove 510, the limit shaft 508 can be pushed toward the connecting plate 2, and the limit shaft 508 will drive the rotating ring 507 to move, and the rotating ring 507 will drive the sliding rod 504 to move. With the movement of the sliding rod 504, the connecting gear 502 will move on the second gear ring 501 toward the first gear ring 310. At this time, the first gear ring 310 may resist the connecting gear 502. When the first gear ring 310 resists the connecting gear 50 After the resistance is performed, as the slide bar 504 continues to move, the connecting sleeve 503 will slide on the slide bar 504, and the spring 506 will shrink. When the limiting shaft 508 moves to the bottom of the limiting groove 510, the limiting shaft 508 can be pushed in the reverse direction to be located at the horizontal position at the bottom of the limiting groove 510. Then the limiting shaft 508 can be released. At this time, the spring 506 will not extend. Then, the rotating drum 302 can be rotated by starting the motor 306. The rotation of the rotating drum 302 will drive the first gear ring 310 to rotate. As the first gear ring 310 rotates, the spring 506 will extend to drive the connecting gear 502 and the first gear ring 310 are meshed, and when the connecting gear 502 is meshed with the first gear ring 310, the connecting gear 502 will rotate as the first gear ring 310 rotates, and the rotation of the connecting gear 502 will drive the second gear ring 501 to rotate, and the rotation of the second gear ring 501 will drive the rotating sleeve 406 to rotate, and the rotation of the rotating sleeve 406 will cause the multiple nozzles 408 to rotate. The multiple nozzles 408 rotate to spray water, which can achieve rapid and comprehensive cleaning of the inside of the mixing barrel 1, avoiding the need for staff to hold a water pipe for flushing, thereby effectively saving physical strength, shortening the cleaning time, and improving the convenience of the cleaning operation.

[0036] See also Figure 5 and Fig. 9As shown, the filter structure 6 includes an outer frame 601 and a filter 602. The outer frame 601 is engaged with the water inlet pipe 402, the filter 602 is fixedly connected to the outer frame 601, the threaded sleeve 603 is threadedly connected to the water inlet pipe 402, the threaded sleeve 603 and the outer frame 601 are in conflict, and a plurality of protrusions 604 are fixedly connected to the threaded sleeve 603. When the filter 602 needs to be replaced, the threaded sleeve 603 can be twisted off from one end of the water inlet pipe 402. By providing a plurality of protrusions 604, the hand can be prevented from slipping during the rotation of the threaded sleeve 603. When the threaded sleeve 603 is twisted off, the outer frame 601 can be taken out from the inside of the water inlet pipe 402, and the filter 602 will be taken out together with the outer frame 601. After being taken out, it is convenient to clean the filter 602, thereby avoiding serious blockage of the filter 602 and effectively ensuring the filtering effect.

[0037] See also Figure 1 , Figure 3 and Figure 8 As shown, the material discharge structure 7 specifically includes a connecting ring 701 and a connecting plate 702, the mixing barrel 1 is rotatably connected with the connecting ring 701, the connecting plate 702 is fixedly connected with the connecting ring 701, the connecting plate 702 is fixedly connected with the baffle 703, the bottom end of the mixing barrel 1 is fixedly connected with a material discharge hopper 704, the baffle 703 is slidably connected to the material discharge hopper 704, the connecting ring 701 is fixedly connected with a handle 705, and the handle 705 is provided with a limiting structure 8. The limiting structure 8 includes a connecting block 801 and a bayonet 802, the mixing barrel 1 is fixedly connected with the connecting block 801, the connecting block 801 is provided with two bayonet 802, the top end of the handle 705 is rotatably connected with a clamping block 803, and the clamping block 803 is engaged with one of the bayonet 802.

[0038] Specifically in the present embodiment, when the grouting material is mixed and stirred, the block 803 can be rotated. When the block 803 is not engaged with one of the bayonet holes 802, the connecting ring 701 can be pushed by the handheld handle 705. The rotation of the connecting ring 701 will drive the baffle 703 to rotate through the connecting plate 702. When the connecting ring 701 moves to a certain position, the block 803 can be engaged with another bayonet hole 802. At this time, the connecting ring 701 cannot continue to rotate, and the baffle 703 will not block the discharge port 9. Therefore, the mixed grouting material inside the mixing barrel 1 can fall into the lower hopper 704, and finally flow out from the end of the lower hopper 704, thereby realizing the discharge of the mixed grouting material.

[0039] When the present invention is in use, when it is necessary to mix and stir the grouting material, the grouting material can be added to the interior of the mixing barrel 1, and then the motor 306 is started, and the output shaft of the motor 306 rotates to drive the first synchronous wheel 307 to rotate, and the first synchronous wheel 307 drives the second synchronous wheel 309 to rotate through the synchronous belt 308, and the rotation of the second synchronous wheel 309 drives the rotating drum 302 to rotate, and the rotation of the rotating drum 302 drives the plurality of stirring rods 303 to rotate. Since the end of the stirring rod 303 is fixedly connected to the first bevel gear 304, and the first bevel gear 304 is meshed with the second bevel gear 305, when the stirring rod 303 rotates in the horizontal direction together with the rotating drum 302, it itself will also rotate in the vertical direction, so that not only the grouting material can be stirred in the horizontal direction, but also the grouting material can be stirred in the horizontal direction. The material can be stirred in the vertical direction, so the stirring effect of the grouting material can be effectively improved. When the grouting material is mixed and stirred, the block 803 can be rotated. When the block 803 is not engaged with one of the bayonet holes 802, the connecting ring 701 can be pushed by the handheld handle 705. The rotation of the connecting ring 701 will drive the baffle 703 to rotate through the connecting plate 702. When the connecting ring 701 moves to a certain position, the block 803 can be engaged with another bayonet hole 802. At this time, the connecting ring 701 cannot continue to rotate, and the baffle 703 will not block the discharge port 9. Therefore, the grouting material mixed in the mixing barrel 1 can fall into the lower hopper 704, and finally flow out from the end of the lower hopper 704, thereby realizing the discharge of the mixed grouting material.

[0040] The external water delivery pipeline can be connected to the water inlet pipe 402. When the interior of the mixing barrel 1 needs to be cleaned, water can enter the water inlet pipe 402, and then the water will enter the interior of the two connecting pipes 403 from the water inlet pipe 402, and then enter the interior of the rotating sleeve 406, and then enter the interior of the two rotating pipes 407, and finally spray out from multiple nozzles 408. During the process of water flowing inside the water inlet pipe 402, large particles of impurities in the water can be filtered through the filter net 602, thereby preventing large particles of impurities from clogging the nozzle 408, thereby effectively improving the stability of use. Next, the limiting shaft 508 is pushed by rotation. When the limiting shaft 508 is horizontally moved from the top of the limiting groove 510 When the position moves to the vertical position on one side of the limit groove 510, the limit shaft 508 can be pushed toward the connecting plate 2, and the limit shaft 508 will drive the rotating ring 507 to move, and the rotating ring 507 will drive the sliding rod 504 to move. With the movement of the sliding rod 504, the connecting gear 502 will move toward the first gear ring 310 on the second gear ring 501. At this time, the first gear ring 310 may resist the connecting gear 502. After the first gear ring 310 resists the connecting gear 502, as the sliding rod 504 continues to move, the connecting sleeve 503 will slide on the sliding rod 504, and the spring 506 will contract. When the limit shaft 508 moves to the bottom of the limit groove 510, the limit shaft 508 can be pushed in the reverse direction to be located at the bottom of the limit groove 510. The spring 506 will not extend at this time, and then the drum 302 can be rotated by starting the motor 306. The rotation of the drum 302 will drive the first gear ring 310 to rotate. As the first gear ring 310 rotates, the spring 506 will extend to drive the connecting gear 502 to engage with the first gear ring 310. When the connecting gear 502 is engaged with the first gear ring 310, the connecting gear 502 will rotate as the first gear ring 310 rotates. The rotation of the connecting gear 502 will drive the second gear ring 501 to rotate. The rotation of the second gear ring 501 will drive the rotating sleeve 406 to rotate. The rotation of the rotating sleeve 406 will cause multiple nozzles 408 to rotate. The water spraying by the multiple nozzles 408 can be realized. The interior of the mixing barrel 1 is now quickly and comprehensively cleaned, avoiding the need for staff to hold a water pipe for flushing, thereby effectively saving physical strength, shortening the cleaning time, and improving the convenience of the cleaning operation. When the filter 602 needs to be replaced, the threaded sleeve 603 can be twisted off from one end of the water inlet pipe 402. By providing a plurality of protrusions 604, the hand can be prevented from slipping during the rotation of the threaded sleeve 603. When the threaded sleeve 603 is twisted off, the outer frame 601 can be taken out from the inside of the water inlet pipe 402, and the filter 602 will be taken out together with the outer frame 601. After taking it out, it is convenient to clean the filter 602, thereby avoiding serious blockage of the filter 602 and effectively ensuring the filtering effect.
