Description
Technical Field
[0001] The present invention belongs to the technical field of underwater building reinforcement devices, and in particular relates to an underwater building reinforcement device for water conservancy projects and a reinforcement method thereof. Background Art
[0002] Underwater structure reinforcement devices used in water conservancy projects refer to facilities specially designed and manufactured to enhance the structural stability and durability of underwater structures (such as bridge piers, dams, reservoir gates, columns and beams, etc.). For example, when reinforcing the exterior of columns and beams, it is necessary to reinforce the outside of the columns and beams with slurry, which refers to the use of specific slurry (such as cement slurry, epoxy resin slurry, etc.). This method is mainly used to improve the bearing capacity, compressive strength and durability of columns and beams.
[0003] The existing water conservancy project underwater building reinforcement device and reinforcement method have the following disadvantages during use: When reinforcing the outside of the column beam by pouring slurry, it is generally done by manually building a bracket on the water surface, and then manually wrapping the fiberglass sleeve on the outside of the column beam. At the same time, the person needs to hold a slurrying device to evenly disperse the slurry, and use the slurry conveying equipment to convey the slurry to the gap formed between the fiberglass sleeve and the column beam. After the slurry solidifies, the entire installation can be removed. However, the uniform dispersion of the slurry and the conveying of the slurry cannot be linked, and at the same time, the slurry is conveyed by manually holding a conveying pipe to circle around the gap for pouring. This method results in low filling efficiency, and at the same time, it is necessary to manually hold a rubber hammer to hammer the outside of the fiberglass sleeve, resulting in high labor intensity. Therefore, a water conservancy project underwater building reinforcement device and a reinforcement method thereof are needed. Summary of the Invention

[0007] As a preferred embodiment, the bottom end of the half gear ring a is fixedly connected to a pumping pump, and the upper part of the half gear ring a is fixedly connected to a feeding pipe. One end of the feeding pipe passes through the half gear ring a and is fixedly connected to the top discharge port of the pumping pump. The other end is bent in an inverted L shape and faces the gap formed between the outer side of the column beam and the inner wall of the glass fiber sleeve. A straight pumping pipe is fixedly connected to the bottom feed port of the pumping pump.

During the rotation process, the gear b is meshed with the half gear ring b, and the rotating barrels drive the multiple stirring rods to rotate, so that the slurry raw materials in the two slurry barrels can be stirred and dispersed evenly to avoid solidification. At the same time, after being dispersed for a certain period of time By starting the two pumping pumps, the slurry can be pumped into the two feeding pipes and sprayed into the gap while stirring, and the two feeding pipes can rotate along the periphery of the feed hopper to spray the material, so that all positions of the gap can be fed evenly. At the same time, the cams will rotate through the rotating cylinder and intermittently squeeze the blocking block, causing the U-shaped movable plate to drive the knocking ball to leave the outside of the fiberglass sleeve. After that, under the rebound action of the spring, the knocking ball can hammer the outside of the fiberglass sleeve at different circumferential positions, making the slurry distribution more dense and enhancing the reinforcement effect. To sum up, the two motors can be driven and linked synchronously to achieve uniform dispersion of the slurry and prevent solidification, and at the same time the extracted slurry can be sprayed out in a circular manner along the feed hopper to the gap, so that the feeding is uniform. In addition, the outer side of the fiberglass sleeve can be knocked at different circumferential positions, thereby greatly improving the efficiency of reinforcing the outer side of the beam and column, greatly reducing the labor intensity of manual construction, and having a good use effect.

[0019] Example
[0020] When the outer side of the column beam 2 is poured with slurry for reinforcement, a support is generally built on the water surface manually, and then the fiberglass sleeve 31 is manually wrapped around the outer side of the column beam 2. At the same time, the person needs to hold a slurrying device to evenly disperse the slurry, and use a slurry conveying device to convey the slurry to the gap formed between the fiberglass sleeve 31 and the column beam 2. After the slurry solidifies, the entire installation can be dismantled. However, the slurry is not evenly dispersed and the slurry is conveyed in a linked manner. At the same time, the slurry is conveyed by manually holding a conveying pipe and circling the gap for pouring. This method results in low filling efficiency, and at the same time, it is necessary to manually hold a rubber hammer to hammer the outer side of the fiberglass sleeve 31, resulting in high labor intensity. To do this, see Figure 1-5 The present invention provides a reinforcement device for underwater buildings in water conservancy projects, comprising: a base 1, a column beam 2 and two symmetrically arranged support platforms 3, semicircular arc-shaped openings are opened on the opposite side walls of the two support platforms 3, glass fiber sleeves 31 are fixed in the arc-shaped openings, sealing gaskets a311 are provided on the opposite mating surfaces of the two glass fiber sleeves 31, feed hoppers 33 are fixed to the top inlets of the two glass fiber sleeves 31, sealing gaskets c331 are provided on the opposite mating surfaces of the two feed hoppers 33, slurry cylinders 32 are fixed to the tops of the two support platforms 3, sealing gaskets b321 are provided on the opposite mating surfaces of the two slurry cylinders 32, and two symmetrically arranged fixing blocks 4 are fixed to the tops of the support platforms 3, and mounting holes are opened on the fixing blocks 4; It also includes a multi-directional rotating filling structure 5, a knocking and compacting structure 6 and a stirring structure 7. The multi-directional rotating filling structure 5 is installed on the slurry barrel 32 and the feed hopper 33; The knocking and compacting structure 6 is also installed on the slurry barrel 32 and the feed hopper 33, and is connected to the multi-directional rotating filling structure 5; The stirring structure 7 is installed on the multi-directional rotating filling structure 5 and is connected to the knocking and compacting structure 6.
[0021] Further as Figure 1-5As shown, it is worth mentioning that the multi-directional rotating filling structure 5 includes a half gear ring a51 that is rotatably sleeved on the outside of the feed hopper 33. The vertical sections of both ends of the half gear ring a51 are convex structures. A semi-annular channel that matches the half gear ring a51 is opened on the outside of the feed hopper 33. The outer side of the half gear ring a51 is meshed with a gear a52. The mounting shaft hole of the gear a52 is fixed to the outer side of the output shaft of the motor 53. The bottom end of the motor 53 is fixed to the outer side of the slurry barrel 32 through the support seat 54. The half gear ring a51 is provided with a semi-annular channel that matches the half gear ring a51. The outer side of the half gear ring a51 is meshed with a gear a52. The mounting shaft hole of the gear a52 is fixed to the outer side of the output shaft of the motor 53. The bottom end of the motor 53 is fixed to the outer side of the slurry barrel 32 through the support seat 54. A pumping pump 56 is fixedly connected to the bottom end of the ring a51, and a feeding pipe 55 is fixedly connected to the upper part of the half gear ring a51. One end of the feeding pipe 55 passes through the half gear ring a51 and is fixedly connected to the top discharge port of the pumping pump 56. The other end is bent in an inverted L shape and faces the gap formed between the outer side of the column beam 2 and the inner wall of the glass fiber sleeve 31. A straight pumping pipe 57 is fixedly connected to the bottom feed port of the pumping pump 56. The bottom end of the straight pumping pipe 57 is connected to the slurry barrel 32 and is used to extract the slurry in the slurry barrel 32.
[0022] The two ends of the two semi-annular channels are opened outwardly, so that the two half gear rings a51 can rotate outside the two feed hoppers 33 after they are matched.
[0023] Further as Figure 1-5 As shown, it is worth mentioning that the knocking and compacting structure 6 includes vertical rods 61 provided on both sides of the material pump 56, the two vertical rods 61 are symmetrically arranged, and a U-shaped movable plate 62 is slid between the two vertical rods 61. The two side walls of the U-shaped movable plate 62 are provided with convex sliding parts 621, and the side walls opposite to each other of the two vertical rods 61 are provided with sliding grooves that match the convex sliding parts 621. A knocking ball 63 is fixedly connected to the end of the U-shaped movable plate 62 facing the outside of the fiberglass sleeve 31, and a guide rod 66 is movably inserted on the two vertical rods 61. The ends of the two guide rods 66 facing the fiberglass sleeve 31 are fixed to the U-shaped At the top of the movable plate 62, a spring 68 is provided between the two connecting blocks 67 and the corresponding vertical rods 61, and the springs 68 are sleeved on the outside of the guide rod 66. The tops of the two ends of the U-shaped movable plate 62 away from the knocking ball 63 are fixed with the same blocking block 64. The blocking block 64 is movably overlapped on the outside of the cam 65 toward the side wall of the knocking ball 63. The cam 65 is fixed to the outside of the rotating cylinder 71, and the rotating cylinder 71 is rotatably sleeved on the outside of the material extraction straight pipe 57. A gear b69 is provided below the cam 65 and is fixed to the outside of the rotating cylinder 71. The outer side of the gear b69 is meshed with a half gear ring b610, and the half gear ring b610 is fixed to the inner wall of the slurry cylinder 32.
[0024] The spring 68 in the accompanying drawings is in a normal state without being stretched or compressed. At the same time, the distance between the two vertical rods 61 can meet the rotation of the cam 65 without causing any obstruction.
[0025] Further as Figure 1-5As shown, it is worth noting that the stirring structure 7 includes a plurality of stirring rods 72 fixed to the outside of the rotating cylinder 71.
[0026] The rotating drum 71 drives the multiple stirring rods 72 to rotate, which can free manual hands and realize automatic and uniform dispersion of the slurry.
[0027] The present application also discloses a method for reinforcing underwater structures in a water conservancy project, comprising the following steps: S1. First, two support platforms 3 are supported and stabilized in water using existing technology. The two support platforms 3 are fixed together by bolts, nuts, and four fixing blocks 4. The two fiberglass sleeves 31 are aligned and wrap around the column beam 2. S2. Pour the slurry raw materials into the two matched slurry barrels 32, and through the multi-directional rotating filling structure 5 combined with the stirring structure 7, the stirring structure 7 can rotate along the periphery of the feed hopper 33 along with the multi-directional rotating filling structure 5, and can also achieve the stirring action of the slurry raw materials in the slurry barrels 32, thereby helping to prevent the slurry from solidifying and affecting the filling reinforcement effect; S3. While the multi-directional rotating filling structure 5 is rotating in a circular manner along the periphery of the feed hopper 33, the knocking and compacting structure 6 is caused to rotate accordingly, and at the same time, the knocking and compacting structure 6 is able to hammer and compact at different positions of the outer circumference of the fiberglass sleeve 31, so that the slurry can be evenly distributed in the gap formed between the outer side of the column beam 2 and the inner wall of the fiberglass sleeve 31; S4. After the slurry solidifies on the outside of the column beam 2, the bolts and nuts can be loosened and the two support platforms 3 can be removed separately.
[0028] In summary: when using the underwater building reinforcement device for water conservancy projects, the slurry raw materials can be poured into the two matched slurry barrels 32, and by starting the two motors 53, the gears a52 are driven to rotate in the same direction respectively, and the gears a52 are meshed with the half gear ring a51, so that the two half gear rings a51 can rotate outside the two matched slurry barrels 32, and the two pumping pumps 56 are rotated along with the two half gear rings a51. During the rotation process, the gears b69 are meshed with the half gear ring b610, so that the rotating barrel 71 drives the multiple stirring rods 72 to rotate, so that the slurry raw materials in the two slurry barrels 32 can be stirred and dispersed evenly to avoid solidification, and dispersed for a certain time. Afterwards, by starting the two extraction pumps 56, the slurry can be drawn into the two filling pipes 55 and sprayed into the gap while stirring, and the two filling pipes 55 can rotate along the periphery of the feed hopper 33 to spray the material, so that all positions of the gap can be fed evenly. At the same time, the cam 65 will rotate through the rotating cylinder 71 and intermittently squeeze the blocking block 64, causing the U-shaped movable plate 62 to drive the knocking ball 63 to leave the outside of the fiberglass sleeve 31. After that, under the rebound action of the spring 68, the knocking ball 63 can hammer the outside of the fiberglass sleeve 31 at different circumferential positions, causing the slurry to be distributed more densely and enhancing the reinforcement effect.
