Description

Technical Field

[0001] The present invention belongs to the technical field of underwater concrete pile foundation pouring, and specifically relates to an underwater concrete pile foundation pouring device. Background Technique

[0002] An underwater concrete pile foundation pouring device is a mechanical equipment or system specifically used for underwater concrete pile foundation construction in underwater environments (such as rivers, lakes, oceans, etc.). Its core purpose is to ensure that the concrete is not diluted or washed away by water during the pouring process, thereby ensuring the strength and integrity of the pile foundation.

[0003] In the existing underwater concrete pile foundation pouring devices, during the underwater pouring process, the conduit method is usually adopted. The conduit is placed into the water, and its lower end is inserted into the interior of the pile foundation. The accumulated water in the conduit is emptied by a drainage ball, and after placing the steel reinforcement cage, concrete pouring operations are carried out. After the drainage ball squeezes and empties the accumulated water inside the conduit, the drainage ball needs to be processed. Usually, the post-floating scheme and the landfill scheme are adopted. In the former, when the drainage ball is discharged, environmental water infiltration and backflow occur, causing the conduit to accumulate water again, reducing the emptying effect. On the other hand, the drainage ball has a certain volume, and it occupies a relatively large space during landfill treatment, affecting the quality of the formed concrete pile and reducing the strength of the formed pile. The comprehensive use effect is not good. Summary of the Invention

[0011] Preferably, the outer surface of the outer pipe is respectively provided with a drain port, an adaptation groove, and a communication port. The drain ports are symmetrically formed on the outside of the outer pipe. The adaptation groove is adapted to the first gear. One end of the communication port communicates with the arc-shaped distribution frame, and the other end communicates with the processing assembly.

[0012] Preferably, the air release assembly includes a conduction cavity, a push block, a thimble, and a second spring. The conduction cavity is formed inside the movable arc plate and communicates with the adaptation cavity at one end. The push block is movably sleeved on the inner side surface of the movable arc plate. One end of the second spring is fixed in the conduction cavity, and the other end is fixedly connected to the push block. The thimble is fixedly connected to the end surface of the push block and is located in the annular groove.

[0013] Preferably, the number of the processing assemblies is two. The two processing assemblies are symmetrically distributed at the center inside the outer pipe. The distance value between adjacent fixed arc plates is less than the arc length value of the movable arc plate.

[0014] The beneficial effects of the present invention are as follows:

[0015] (1) By utilizing the cooperation of the air supply assembly and the processing assembly, during the downward drainage process of the drainage ball, the accumulated water in the inner conduit is first squeezed into the space between the inner conduit and the outer pipe, and the excess accumulated water is discharged outward through the intermediate space. After the drainage inside the inner conduit is completed, the air pump in the air supply assembly introduces pressurized air into the inside of the processing assembly. By using the air pressure force, the movable arc plate in the processing assembly is pushed to slide along the arc-shaped track, thereby further squeezing out the accumulated water between the inner conduit and the outer pipe. After the drainage ball completes drainage, the outer drainage is closed, effectively avoiding the situation of drainage backflow at the bottom of the drainage ball, effectively realizing the plugging treatment after drainage, greatly improving the actual drainage effect, avoiding the interference of accumulated water during pouring, providing the final pouring molding quality, and having good use effects.

[0016] (2) By reusing the cooperation of the air supply component and the processing component, after filling the gas inside the processing component and moving the movable arc plate, as the internal accumulated water is drained, compressed air is further input, causing the air pressure inside the processing component to continuously increase. After the movable arc plate in the processing component moves to the limit position, with the increasing air pressure, the push block in the air release component is pushed to move, overcoming the elasticity of the second spring, and simultaneously pushing the thimble to move. The rotated air release component is aligned with the water outlet, and the thimble driven by extrusion squeezes and crushes the drainage balls extruded to the bottom of the inner conduit along both sides, causing the shape of the drainage balls to collapse after being broken, reducing their volume. Combined with the continuously poured concrete, the bottom burial is completed, reducing the burial volume of the drainage balls and the impact on the concrete pile after burial. On the one hand, rapid burial is achieved, and on the other hand, the forming quality of the concrete pile after burial is improved. It is convenient to use in practice and has good use effects.

[0017] (3)By utilizing the socket assembly effect of the outer tube and the inner conduit, and adding a driving component arranged on the outside of the outer tube, after draining and sealing the accumulated water in the space between the outer tube and the inner conduit, by further starting the driving component and driving the inner conduit to slowly rotate in the outer tube, during the solidification of the internal concrete, it is ensured that the inner conduit on the outside of the concrete is always in dynamic contact with the concrete. As the complete solidification is completed, it is ensured that the inner wall of the inner conduit is in a separated state from the concrete, avoiding adhesion, improving the detachment effect of the inner conduit from the formed concrete pile, reducing strain, and improving the continuous pouring efficiency. The comprehensive use effect is good. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation manner

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] As Figures 1 to 8 shown, an underwater concrete pile foundation pouring device provided by an embodiment of the present invention includes a mounting frame 1, a pouring port 2, a pushing part 3 and an inner conduit 5. An outer tube 4 is sleeved outside the inner conduit 5. The upper end of the outer tube 4 is fixedly connected to the mounting frame 1. A processing assembly 7 is provided between the inner conduit 5 and the outer tube 4. A drainage ball 8 is sleeved inside the inner conduit 5. A positioning arc plate 9 is fixedly provided at the top of the drainage ball 8. A drive assembly 6 is fixedly provided outside the outer tube 4. The drive assembly 6 drives the inner conduit 5 to rotate in the outer tube 4. An air supply assembly 10 is fixedly provided outside the outer tube 4. The air supply assembly 10 is internally communicated with the processing assembly 7. An air release assembly 11 is provided inside the processing assembly 7. The processing assembly 7 includes a fixed arc plate 71, a movable arc plate 72, a first spring 73 and a fitting cavity 74. The fixed arc plate 71 is fixedly connected to the inner wall of the outer tube 4. The movable arc plate 72 is movably sleeved in the fixed arc plate 71. The first spring 73 is fixedly connected in the fitting cavity 74 and the other end is fixedly connected to the movable arc plate 72.

[0029] Embodiment 1: During use, start the lifting mechanism externally connected to the outside of the mounting frame 1 to drive the synchronous movement of the mounting frame 1 and the outer pipe 4, insert them downward along the water surface direction into the water, and synchronously move the outer pipe 4 and the inner conduit 5 into the foundation base of the pile foundation. Put the drainage ball 8 into the interior of the pipe body 51 of the inner conduit 5. The drainage ball 8 floats inside the pipe body 51, and one end of the steel reinforcement cage for pouring is sleeved into the interior of the inner conduit 5. The bottom of the steel reinforcement cage is positioned at the top of the positioning arc plate 9. Use an externally connected pushing device to push the steel reinforcement cage downward in the inner conduit 5, squeeze the drainage ball 8 to move downward along the interior of the pipe body 51, and push the water flow inside the pipe body 51 to be squeezed out through the water outlet 53 into the space between the outer pipe 4 and the inner conduit 5. And as continuous downward squeezing occurs, the internal water flow discharges upward along the gap space between the outer pipe 4 and the inner conduit 5 and is discharged through the drainage port 12. The steel reinforcement cage moves and is sleeved into the interior of the inner conduit 5 to complete the drainage treatment. Subsequently, start the pushing part 3 to push the pouring port 2 to move above the inner conduit 5. An externally connected concrete release pipeline inputs concrete into the pouring port 2 and continuously pours it into the inner conduit 5 for pouring operations. And start the air supply assembly 10. The air pump 101 inputs pressurized air through the air pipe 103 and the arc-shaped distribution frame 102 into the communication port 14 and along the communication port 14 into the adaptation cavity 74 of the processing assembly 7. As the air pressure in the adaptation cavity 74 increases, push the movable arc plate 72 to slide along the interior of the adaptation cavity 74, and push along the arc-shaped estimation, stretching the first tension spring 73 at the same time. The outer large end of the movable arc plate 72 further squeezes the liquid in the two groups of processing assemblies 7. As the two groups of movable arc plates 72 are synchronously squeezed, all the water between the inner conduit 5 and the outer pipe 4 is squeezed out, and drive the air release assembly 11 on the side of the movable arc plate 72 to rotate along the annular groove 52 to the water outlet 53. As the supply of pressurized air continues, the air pressure inside the adaptation cavity 74 continues to rise and continuously fills into the conduction cavity 111. As the air pressure inside the conduction cavity 111 rises, continuously push the push block 112 to move. While stretching the second tension spring 114, drive the thimble 113 to move along the water outlet 53. And as the thimble 113 continuously moves and contacts the drainage ball 8, the drainage ball 8 is sharply squeezed and ruptured, its shape collapses, the poured concrete quickly fills, completing the rupture and burial of the drainage ball 8, and continue with the subsequent pouring to complete the overall pouring.

[0030] First, by utilizing the cooperative effect of the air supply component 10 and the processing component 7, during the downward drainage process of the drainage ball 8, the accumulated water in the inner conduit 5 is first squeezed into the space between the inner conduit 5 and the outer tube 4, and the excess accumulated water is discharged outward through the intermediate space. After the drainage inside the inner conduit 5 is completed, the pressure air is introduced into the interior of the processing component 7 by the air pump 101 in the air supply component 10. By using the air pressure acting force, the movable arc plate 72 in the processing component 7 is pushed to slide along the arc track, thereby further squeezing out the accumulated water between the inner conduit 5 and the outer tube 4. After the drainage ball 8 completes drainage, the outer drainage is closed, effectively avoiding the situation of drainage backflow at the bottom of the drainage ball 8, effectively realizing the plugging treatment after drainage, greatly improving the actual drainage effect, avoiding the interference of accumulated water during pouring, providing the final pouring molding quality, and having good use effect.

[0031] In addition, by once again utilizing the cooperative effect of the air supply component 10 and the processing component 7, after the interior of the processing component 7 is filled with gas and the movement of the movable arc plate 72 is completed, as the internal accumulated water is emptied, the pressure air is further input, causing the air pressure inside the processing component 7 to continuously increase. After the movable arc plate 72 in the processing component 7 moves to the limit position, with the continuously increasing air pressure, the push block 112 in the air release component 11 is pushed to move, overcoming the elasticity of the second spring 114, and simultaneously pushing the movement of the ejector pin 113. The rotated air release component 11 is aligned with the water outlet 53, and the ejector pin 113 pushed by extrusion squeezes and breaks the drainage ball 8 that has been squeezed to the bottom of the inner conduit 5 along both sides, causing the shape of the drainage ball 8 to collapse after being broken, reducing the volume, and cooperating with the continuously poured concrete to complete the bottom burial, reducing the burial volume of the drainage ball 8 and reducing the influence of the buried drainage ball 8 on the concrete pile. On the one hand, it realizes quick burial, and on the other hand, it improves the molding quality of the concrete pile after burial, is convenient for actual use, and has good use effect.

[0032] Embodiment 2: After the basic pouring is completed, the driving component 6 is started. The motor 61 in the driving component 6 is started, driving the first gear 62 to rotate. The first gear 62 rotates and drives the meshing second gear 63 to rotate, causing the second gear 63 to drive the inner conduit 5 to rotate, so that the inner conduit 5 slowly rotates in the outer tube 4, and the inner wall of the pipe body 51 has dynamic friction with the relatively fixed concrete. After the internal concrete solidifies, the relative peeling between the outer wall of the formed pile and the inner conduit 5 is maintained. The external lifting mechanism is started to quickly lift the outer tube 4 and the inner conduit 5 out of the water, complete the separation and demolding, move the position and carry out the pouring operation for the next group of pile foundations.

[0033] First, by utilizing the socket assembly effect of the outer pipe 4 and the inner conduit 5, a driving component 6 is added and arranged on the outer side of the outer pipe 4. After the drainage and sealing of the water accumulated in the space between the outer pipe 4 and the inner conduit 5 are completed, the driving component 6 is further started to drive the inner conduit 5 to rotate slowly in the outer pipe 4. During the solidification of the internal concrete, it is ensured that the inner conduit 5 on the outer side of the concrete is always in dynamic contact with the concrete. With the completion of full solidification, it is ensured that the inner wall of the inner conduit 5 is in a separated state from the concrete, avoiding adhesion, improving the subsequent detachment effect of the inner conduit 5 from the formed concrete pile, reducing strain, improving the continuous pouring efficiency, and having good comprehensive use effects.

[0034] Among them, the pouring port 2 is slidably installed in the mounting frame 1, the pushing part 3 is fixed in the mounting frame 1, and the movable end is fixedly connected to the pouring port 2.

[0035] By utilizing the pushing part 3 to push the pouring port 2 to move, changing the position of the pouring port 2, and cooperating with the external concrete input end, the concrete input and pouring are completed.

[0037] By utilizing the inner conduit 5 to complete the placement of the steel reinforcement cage and the filling of the concrete, the ring groove 52 is used to adapt to the rotation of the air release component 11, so that the air release component 11 is aligned with the water outlet 53, and the subsequent collapse treatment of the drainage ball 8 is completed, reducing the volume ratio of the drainage ball 8. The water outlet 53 is used to guide the water flow to discharge from the inner conduit 5.

[0038] Among them, the driving component 6 includes a motor 61, a first gear 62, a second gear 63, and a snap ring 64.

[0039] By utilizing the driving component 6 to provide driving force and cooperating with the meshing rotation of the first gear 62 and the second gear 63, the slow rotation of the inner conduit 5 in the outer pipe 4 is realized. After the concrete pouring is completed, the dynamic contact is utilized to reduce the adhesion after the concrete solidifies and improve the subsequent separation effect.

[0040] Among them, the air supply component 10 includes an air pump 101, an arc-shaped distribution frame 102, and an air pipe 103. The air pump 101 is fixed on the outer side of the outer pipe 4 through a support plate, the arc-shaped distribution frame 102 is fixedly connected to the outer side of the outer pipe 4, and the air pipe 103 is fixedly connected between the air pump 101 and the arc-shaped distribution frame 102.

[0041] By utilizing the air supply component 10 to provide pressurized air, and by taking advantage of the effect of the conducted pressurized air, the operation of the processing component 7 is realized, further draining accumulated water, preventing backflow, and further using the effect of the pressurized air to complete the movement of the air release component 11, thus realizing the puncture and collapse of the drainage ball 8.

[0042] Wherein, drain openings 12, fitting grooves 13 and communication ports 14 are respectively formed on the outer surface of the outer tube 4. The drain openings 12 are symmetrically formed on the outer side of the outer tube 4. The fitting grooves 13 are adapted to the first gear 62. One end of the communication port 14 is communicated with the arc-shaped distribution frame 102, and the other end is communicated with the processing component 7.

[0043] Upward drainage is completed by utilizing the drain openings 12 to discharge the accumulated water inside the outer tube 4. The communication port 14 is used to conduct the air supply component 10 and the processing component 7, and the fitting grooves 13 are adapted to the first gear 62.

[0044] Wherein, the air release component 11 includes a conduction cavity 111, a push block 112, a thimble 113 and a second spring 114. The conduction cavity 111 is formed inside the movable arc plate 72 and one end thereof is communicated with the fitting cavity 74. The push block 112 is movably sleeved on the inner side surface of the movable arc plate 72. One end of the second spring 114 is fixed in the conduction cavity 111 and the other end is fixedly connected to the push block 112. The thimble 113 is fixedly connected to the end face of the push block 112 and is located in the annular groove 52. The number of the processing components 7 is two groups, and the two groups of processing components 7 are symmetrically distributed inside the outer tube 4. The distance value between adjacent fixed arc plates 71 is less than the arc length value of the movable arc plate 72.

[0045] The air release component 11 realizes shape collapse by puncturing the thick-walled drainage ball 8 filled with internally expanded gas, reducing the structural influence on the pile during landfill.

[0046] Working principle and usage process of the present invention: During use, start the lifting mechanism externally connected to the outside of the mounting frame 1, drive the mounting frame 1 and the outer pipe 4 to move synchronously, insert them downward along the water surface into the water, and make the outer pipe 4 and the inner conduit 5 move synchronously into the foundation of the pile foundation. Put the drainage ball 8 into the inside of the pipe body 51 of the inner conduit 5. The drainage ball 8 floats inside the pipe body 51, and one end of the steel reinforcement cage for pouring is sleeved into the inside of the inner conduit 5. The bottom of the steel reinforcement cage is positioned at the top of the positioning arc plate 9. Use an externally connected pushing device to push the steel reinforcement cage to move downward in the inner conduit 5, squeeze the drainage ball 8 to move downward along the inside of the pipe body 51, and push the water flow inside the pipe body 51 to be extruded along the water outlet 53 into the space between the outer pipe 4 and the inner conduit 5. And as it is continuously squeezed downward, the internal water flow is discharged upward through the gap space between the outer pipe 4 and the inner conduit 5 and discharged through the drainage port 12. The steel reinforcement cage moves and is sleeved into the inside of the inner conduit 5 to complete the drainage treatment. Subsequently, start the pushing part 3, push the pouring port 2 to move above the inner conduit 5, and an externally connected concrete release pipeline inputs concrete into the pouring port 2 and continuously pours it into the inner conduit 5 for pouring operation. And start the air supply component 10. The air pump 101 inputs pressurized air into the communication port 14 through the air pipe 103 and the arc-shaped distribution frame 102 and inputs it along the communication port 14 into the adaptation cavity 74 of the processing component 7. As the air pressure in the adaptation cavity 74 increases, push the movable arc plate 72 to slide along the inside of the adaptation cavity 74, and push along the arc-shaped estimation, stretching the first tension spring 73 at the same time. The outer large end of the movable arc plate 72 further squeezes the liquid in the two groups of processing components 7. As the two groups of movable arc plates 72 are synchronously squeezed, all the water between the inner conduit 5 and the outer pipe 4 is squeezed out, and drive the air release component 11 on the side of the movable arc plate 72 to rotate along the annular groove 52 to the water outlet 53. As the pressurized air continues to be supplied, the air pressure inside the adaptation cavity 74 continues to rise and continuously fills the conduction cavity 111. As the air pressure inside the conduction cavity 111 rises, continue to continuously push the push block 112 to move, stretch the second tension spring 114 at the same time, drive the ejector pin 113 to move along the water outlet 53, and as the ejector pin 113 continuously moves and contacts the drainage ball 8, the drainage ball 8 is sharply squeezed and broken, its shape collapses, the poured concrete quickly fills, completes the rupture and burial of the drainage ball 8, and continues the subsequent pouring to complete the overall pouring; after the foundation pouring is completed, start the drive component 6. The motor 61 in the drive component 6 starts, drives the first gear 62 to rotate, the first gear 62 rotates and drives the engaged second gear 63 to rotate, so that the second gear 63 drives the inner conduit 5 to rotate, so that the inner conduit 5 slowly rotates in the outer pipe 4, and the inner wall of the pipe body 51 has dynamic friction with the relatively fixed concrete. After the internal concrete solidifies, keep the outer wall of the formed pile peeled off from the inner conduit 5 relatively. Start the externally connected lifting mechanism, quickly lift the outer pipe 4 and the inner conduit 5 out of the water, complete the separation and unloading, move the position and carry out the pouring operation for the next group of pile foundations.
