Description

Technical Field

[0001] The present invention relates to the technical field of municipal construction, and specifically to a construction method for a quickly installed and disassembled aluminum formwork for drainage ditches. Background Art

[0002] A drainage ditch is a ditch structure used to guide, collect, and discharge surface water or groundwater. Its main functions are to prevent waterlogging, reduce soil erosion, protect building foundations or roads, and maintain the normal operation of the regional drainage system; for current drainage ditches, during construction, in order to shorten the construction period, prefabricated components of reinforced concrete structures are often selected.

[0003] For example, the patent with the publication number CN 113826942 A discloses a construction method for a quickly installed and disassembled wooden formwork for drainage ditches, including the process of concrete preparation, the process of placing the wooden formwork mold, the process of quantitatively adding concrete, the process of closing the wooden formwork mold, the process of waiting for setting, and the process of opening the mold and taking out. The specific process is as follows: S1. Concrete preparation process... S6. Opening the mold and taking out process. By opening the mold and cooperating with knocking, the mold can be separated from the prefabricated component of the water channel, so that the prefabricated component of the water channel after setting can be taken out, and the mold can be cleaned for reuse.

[0039] By setting the aluminum formwork relative to the wooden formwork, its inner wall is smoother, the connection force between the aluminum formwork and the solidified concrete is relatively small, the precast channel member can be taken out more conveniently, and the cleaning is more convenient. In addition, when knocking out the precast channel member, the aluminum formwork has stronger bearing capacity, which can effectively reduce the risk of damage and has a longer service life.

Then, place steel bars in the V-shaped lower mold 2 and pour concrete through the quantitative feeding device. Next, install the V-shaped upper mold 1 onto the V-shaped lower mold 2, and install connecting parts in the second installation part 7 and the first installation part 6 to complete the mold closing; after the concrete solidifies, open the mold; by knocking on the knocking plate 5, the V-shaped upper mold 1 and the V-shaped lower mold 2 can be quickly separated. The structure is simple and more convenient to use. Moreover, with the setting of the second installation part 7 and the first installation part 6, the third threaded hole 12 and the second threaded hole 9, and the first threaded hole 8 and the fourth threaded hole 13, the mold closing and opening operations can be completed quickly, which is convenient to use and has strong practicability.

[0045] Embodiment 3

[0046] Based on the above Embodiment 1, as Figures 3 - 4 shown, in steps S1 and S3, the quantitative feeding device includes a feeding box 14. At the lower end of the feeding box 14, several support rods 18 are fixedly arranged. On the support rods 18, there are traveling wheels 22. Inside the feeding box 14, there is a mixing box 17. On the left and right sides of the feeding box 14, two feeding funnels 30 are fixedly and penetratingly arranged. The lower end of the feeding funnel 30 is connected to a feeding box 26 in a through manner. The feeding box 26 is fixedly connected to the upper inner wall of the feeding box 14. The lower side of the feeding box 26 is connected to a feeding pipe 15 in a through manner. The feeding pipe 15 is fixedly extended into the mixing box 17. At the lower end of the mixing box 17, there is a discharge pipe 21, and the discharge pipe 21 is fixedly extended out of the feeding box 14.

[0047] Among them, preferably, an eccentric position on the upper inner wall of the feeding box 14 is fixedly provided with a motor 27. The lower output end of the motor 27 is fixedly connected to a rotating rod. At the lower end of the rotating rod, there is a first gear 25. On the upper side wall of the mixing box 17, a rotating rod 16 is rotatably penetrated. At the upper end of the rotating rod 16, there is a gear rod 28. The gear rod 28 is meshed with the first gear 25. On the upper inner wall of the mixing box 17, there is also a sleeve 43 rotatably arranged. On the rotating rod 16, there is a connection key, and in the sleeve 43, there is a keyway. The rotating rod 16 and the sleeve 43 are connected through the cooperation of the connection key and the keyway. On the sleeve 43, several mixing rods 24 are fixedly arranged.

[0048] The working principle and beneficial effects of the above technical solution are as follows: Substances such as concrete and additives are added into the feeding box 26 through the feeding hopper 30. Then the materials enter the mixing box 17 through the feeding pipe 15. At this time, the motor 27 is started. The motor 27 drives the rotating rod to rotate. The rotating rod drives the first gear 25 to rotate. The first gear 25 drives the gear rod 28 to rotate. The gear rod 28 drives the rotating rod 16 to rotate. The rotating rod 16 drives the sleeve 43 to rotate through the connecting key and keyway. The sleeve 43 drives a number of mixing rods 24 to rotate, so as to mix the concrete and additives to be mixed in the mixing box 17. By driving the first gear 25 to rotate by the motor 27, the first gear 25 drives the gear rod 28 to rotate, and then the rotating rod 16, the sleeve 43 and the mixing rod 24 are rotated, the mixing operation can be quickly completed. The structure is simple, the use is convenient, and the practicability is strong.

[0049] Example 4

[0050] On the basis of the above Example 3, as Figures 3 - 6 shown, a linear driving member 29 and a timer are also fixedly arranged on the upper inner wall of the delivery box 14. The timer is electrically connected to the linear driving member 29. The lower output end of the linear driving member 29 is fixedly connected to a driving plate 31. The driving plate 31 is rotatably connected to the rotating rod 16. A stop rod 23 is fixedly arranged at the lower end of the rotating rod 16. The stop rod 23 extends downward and slides out of the sleeve 43. A stop block 19 is fixedly arranged at the lower end of the stop rod 23.

[0051] Among them, preferably, a first baffle 33 is rotatably arranged in the feeding pipe 15. The mutually close sides of the first baffles 33 are fixedly connected to a rotating shaft 34. The rotating shaft 34 is rotatably and sealingly extended out of the feeding pipe 15. A second gear 35 is fixedly arranged on the mutually close sides of the rotating shaft 34. Tooth plates 40 are fixedly arranged on the left and right sides of the driving plate 31. The tooth plates 40 are meshed and connected with the second gear 35.

[0052] Among them, the timer is used to calculate the driving duration of the linear driving member 29, that is, the linear driving member 29 will drive the driving plate 31 to move upward. When the driving duration exceeds a certain time (this time is determined by those skilled in the art), the linear driving member 29 will drive the driving plate 31 to move downward;

[0053] The working principle and beneficial effects of the above technical solution are as follows: When concrete enters the feeding box 26, start the linear driving member 29. The linear driving member 29 drives the driving plate 31 to move. The driving plate 31 drives the rotating rod 16 to move (the gear rod 28 and the first gear 25 are always meshed). The driving plate 31 drives the toothed plate 40 to move. The toothed plate 40 drives the second gear 35 to rotate. The second gear 35 drives the rotating shaft 34 to rotate. The rotating shaft 34 drives the first baffle 33 to rotate, so that the concrete can pass through the feeding pipe 15, and then start the motor 27. With the above structure, when the driving plate 31 moves, the blockage of the feeding pipe 15 can be opened, and the material can pass through quickly. At the same time, the downward movement of the rotating rod 16 will drive the downward movement of the blocking rod 23, and the blocking rod 23 drives the blocking block 19 to block the discharge pipe 21, so that the concrete will not flow out during the mixing process. The above structure is simple and convenient to use, and can quickly complete the mixing of materials and the opening or blocking of the material passage.

[0054] Embodiment 5

[0055] On the basis of the above Embodiment 4, as Figures 3 - 6 shown, a connecting rod 44 is fixedly connected to the rear side of the driving plate 31. A sliding groove is provided on the rear side wall of the feeding box 14. The connecting rod 44 extends out of the feeding box 14 from the sliding groove. A driving rod 45 is fixedly arranged at the lower end of the rear side of the connecting rod 44. A rack is fixedly arranged on the driving rod 45. A second baffle 20 is arranged in the discharge pipe 21. A rotating shaft 32 is fixedly connected to the rear side of the second baffle 20. The rotating shaft 32 rotatably extends out of the discharge pipe 21 in a sealed manner. A third gear 46 is fixedly arranged at the rear end of the rotating shaft 32. The third gear 46 is meshed with the rack.

[0056] The working principle and beneficial effects of the above technical solution are as follows: When the driving plate 31 moves downward, the driving plate 31 drives the connecting rod 44 to move downward. The connecting rod 44 drives the driving rod 45 to move downward. The driving rod 45 drives the rack to move. The rack drives the third gear 46 to rotate. The third gear 46 drives the rotating shaft 32 to rotate. The rotating shaft 32 drives the second baffle 20 to open the blockage of the discharge pipe 21. Through the blockage of the second baffle 20 and the blocking block 19, the leakage of concrete during mixing can be minimized as much as possible. And only by driving the driving plate 31 downward by the linear driving member 29, the opening of the first baffle 33, the closing of the second baffle 20 and the blocking of the blocking block 19 can be realized, so that the mixing in the mixing box 17 can be more perfect. At the same time, when the driving plate 31 moves downward, the mixing rod 24 is still rotating and always performing the mixing work. In addition, during the mixing process, the feeding box 14 can be pushed, so that the whole device can be moved, and the discharge pipe 21 can be aligned with different aluminum templates in turn, making the transportation more convenient and the practicability stronger.

[0057] Embodiment 6

[0058] On the basis of the above-mentioned Embodiment 5, as Figures 3 - 6 shown, L-shaped rods 38 are symmetrically and fixedly arranged on the driving rod 45 from left to right, and wedge-shaped pushing blocks 39 are fixedly arranged on the sides of the L-shaped rods 38 close to each other; pressing plates 36 are symmetrically and slidably arranged in the mixing box 17 from left to right, springs 37 are fixedly arranged on the sides of the pressing plates 36 away from each other, the springs 37 are fixedly connected to the inner walls on the left and right sides of the mixing box 17, through grooves are symmetrically formed in the rear side of the mixing box 17 from left to right, the through grooves communicate with the feeding box 14, extension rods are fixedly connected to the rear sides of the pressing plates 36, the extension rods extend out of the feeding box 14 from the through grooves, cross bars 41 are fixedly connected to the rear ends of the extension rods, and wedge-shaped blocks 42 are fixedly arranged on the cross bars 41, and the wedge-shaped pushing blocks 39 cooperate with the wedge-shaped blocks 42.

[0059] The working principle and beneficial effects of the above technical solution are as follows: when the driving plate 31 moves upward, the driving plate 31 drives the connecting rod 44 to move upward, the connecting rod 44 drives the driving rod 45 to move upward, the driving rod 45 drives the L-shaped rod 38 to move upward, the L-shaped rod 38 drives the wedge-shaped pushing block 39 to move upward and push the two wedge-shaped blocks 42 to move towards each other, the wedge-shaped blocks 42 drive the cross bar 41 to move towards each other, and the cross bar 41 drives the pressing plate 36 to move towards each other, so as to extrude the concrete in the mixing box 17, enabling the concrete to be quickly discharged; when the driving plate 31 moves upward, the second baffle 20 releases the block, the stopper 19 releases the block, and the pressing plate 36 moves to extrude the concrete (at this time, whether the first baffle 33 releases the block does not affect the use of the whole device, and the concrete has been put in place). Through the cooperation of the above structures, after the concrete enters the mixing box 17, it can be mixed for a period of time first (the mixing time is determined by those skilled in the art), and then the running time of the linear driving member 29 is controlled by a timer, that is, the operations of the second baffle 20, the stopper 19 and the pressing plate 36 are controlled. The degree of cooperation of the structure is high and the practicability is strong.

[0060] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms.
