Description

Technical Field

[0001] The invention belongs to the technical field of concrete pile foundation casting, and in particular relates to an underwater concrete pile foundation casting device. Background Art

[0002] The underwater concrete pile foundation casting device is a mechanical equipment or system specially used for 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 underwater concrete pile foundation casting device in the prior art, a conduit method is usually used in the process of underwater casting. The conduit is placed in water and its lower end is inserted into the interior of the pile foundation. The accumulated water in the conduit is emptied by a drain ball, and the concrete casting operation is carried out after a steel cage is placed. After the drain ball squeezes and empties the accumulated water in the conduit, the drain ball needs to be processed. The post-foundation floating scheme and the landfill scheme are usually adopted. In the former, the environmental water infiltration and backflow occur when the drain ball is discharged, causing water to accumulate again in the conduit, reducing the emptying effect. On the other hand, the drain ball has a certain volume and occupies a considerable space during landfill treatment, which affects the quality of the concrete formed piles and reduces the strength of the formed piles. The comprehensive use effect is not good. Summary of the invention

[0012] Preferably, the number of the processing components is two groups, the two groups of processing components are centrally symmetrically distributed inside the outer tube, and the spacing between adjacent fixed arc plates is smaller than the arc length of the movable arc plate.

[0013] The beneficial effects of the present invention are as follows: (1) The present invention utilizes the cooperation of the air supply component and the processing component. During the downward movement of the drainage ball, the accumulated water in the inner conduit is first squeezed into the space between the inner conduit and the outer tube, and the excess accumulated water is discharged outwardly by utilizing the intermediate space. After the inner conduit is drained, the pressurized air is introduced into the interior of the processing component by the air pump in the air supply component.

After the movable arc plate in the processing component moves to the limit position, as the air pressure continues to increase, the push block in the air discharge component is pushed to move, the elasticity of the spring 2 is overcome, and the movement of the ejector pin is simultaneously pushed. The air discharge component after rotation is aligned with the water outlet, and the ejector pin pushed by the extrusion is used to squeeze and crush the drainage ball squeezed to the bottom of the inner guide tube along both sides, so that the shape of the drainage ball collapses after crushing and the volume is reduced. In combination with the continuous pouring of concrete, the bottom is buried, the buried volume of the drainage ball is reduced, and the influence of the drainage ball on the concrete pile after burial is reduced. On the one hand, quick burial is achieved, and on the other hand, the molding quality of the concrete pile after burial is improved. It is convenient to use in practice and has a good effect.

[0015] (3) The present invention utilizes the sleeve assembly effect of the outer tube and the inner tube, adds a driving component, and arranges it on the outside of the outer tube. After the water accumulated in the space between the outer tube and the inner tube is emptied and sealed, the driving component is further started to drive the inner tube to rotate slowly in the outer tube. During the solidification of the internal concrete, the inner tube outside the concrete is always kept in dynamic contact with the concrete. As the solidification is completed, the inner wall of the inner tube is kept separated from the concrete to avoid adhesion, thereby improving the subsequent separation effect of the inner tube and the formed concrete pile, reducing strain, and improving the continuous pouring efficiency. The comprehensive use effect is good. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Embodiment 1: When in use, the lifting mechanism connected to the outside of the mounting frame 1 is started to drive the mounting frame 1 and the outer tube 4 to move synchronously, and the mounting frame 1 and the outer tube 4 are inserted into the water upward and downward along the water surface, and the outer tube 4 and the inner conduit 5 are synchronously moved to the base of the pile foundation, and the drainage ball 8 is put into the inside of the tube body 51 of the inner conduit 5, and the drainage ball 8 floats inside the tube body 51, and one end of the steel cage to be poured is inserted into the inside of the inner conduit 5, and the bottom of the steel cage is positioned on the top of the positioning arc plate 9. An external pushing device is used to push the steel cage downward in the inner conduit 5, and squeeze the drainage ball 8 to move downward along the inside of the tube body 51 , pushing the water flow inside the pipe body 51 along the water outlet 53 to be squeezed into the space between the outer pipe 4 and the inner conduit 5, and with continuous downward squeezing, the internal water flow is discharged upward along the gap space between the outer pipe 4 and the inner conduit 5, and discharged through the drain port 12, the steel cage moves into the inner conduit 5, and the drainage process is completed, then the pushing part 3 is started, pushing the pouring port 2 to move to the top of the inner conduit 5, the external concrete release pipeline puts concrete into the pouring port 2, and continuously pours it into the inner conduit 5, and the pouring operation is carried out, and the air supply component 10 is started, and the air pump 101 presses the concrete into the pouring port 2. The forced air is input into the connecting port 14 through the air pipe 103 and the arc-shaped distribution frame 102, and is input into the adapting cavity 74 of the processing component 7 along the connecting port 14. As the air pressure in the adapting cavity 74 increases, the movable arc plate 72 is pushed to slide along the inside of the adapting cavity 74, and is pushed along the arc. While the spring 1 73 is stretched, the outer large end of the movable arc plate 72 further squeezes the liquid in the two groups of processing components 7. With the synchronous squeezing of the two groups of movable arc plates 72, all the water between the inner conduit 5 and the outer tube 4 is squeezed out, and the air release component 11 on the side of the movable arc plate 72 is driven along the annular groove 5. 2 rotates to the water outlet 53. With the continuous supply of pressurized air, the air pressure inside the adapting cavity 74 continues to increase and is continuously filled into the conducting cavity 111. With the increase of the air pressure inside the conducting cavity 111, the push block 112 is continuously pushed to move. While the pulling spring 114 is stretched, the ejector pin 113 is driven to move along the water outlet 53. With the ejector pin 113 continuously moving and contacting the drainage ball 8, the drainage ball 8 is sharply squeezed and ruptured, and the shape collapses. The poured concrete is quickly filled to complete the rupture and burial of the drainage ball 8, and the subsequent pouring is continued to complete the full pouring.

[0021] Firstly, by utilizing the cooperation of the air supply component 10 and the processing component 7, during the downward movement 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 outwardly by utilizing the intermediate space. After the internal drainage of the inner conduit 5 is completed, the pressurized air is introduced into the interior of the processing component 7 by the air pump 101 in the air supply component 10, and the movable arc plate 72 in the processing component 7 is pushed to slide along the arc trajectory by utilizing the force of air pressure, thereby further squeezing out the accumulated water between the inner conduit 5 and the outer tube 4. After the drainage ball 8 completes the drainage, the outer drainage is closed, thereby effectively avoiding the drainage backflow of the drainage ball 8 at the bottom, and effectively realizing the sealing treatment after drainage, which greatly improves the actual drainage effect, avoids the interference of accumulated water during pouring, provides the final casting molding quality, and has a good use effect.

[0022] In addition, by utilizing the cooperation of the air supply component 10 and the processing component 7 again, after the gas filling inside the processing component 7 is completed and the movement of the movable arc plate 72 is completed, as the internal accumulated water is emptied, pressurized air is further input, so that the air pressure inside the processing component 7 continues to increase. After the movable arc plate 72 in the processing component 7 moves to the limit position, as the air pressure continues to increase, the push block 112 in the air release component 11 is pushed to move, overcoming the elasticity of the spring 114, and synchronously pushing the movement of the ejector pin 113, the air release component 11 after rotation is aligned with the water outlet 53, and the ejector pin 113 pushed by the extrusion is squeezed and crushed along both sides to squeeze the drainage ball 8 squeezed to the bottom of the inner guide tube 5, so that the shape of the drainage ball 8 collapses after crushing and the volume is reduced, and the bottom is buried in cooperation with the continuously poured concrete, the buried volume of the drainage ball 8 is reduced, and the influence of the drainage ball 8 on the concrete pile after burial is reduced. On the one hand, quick burial is achieved, and on the other hand, the molding quality of the concrete pile after burial is improved. It is convenient to use in practice and has a good effect.

[0023] Embodiment 2: After the foundation pouring is completed, the driving assembly 6 is started, and the motor 61 in the driving assembly 6 is started, driving the gear 1 62 to rotate, and the gear 1 62 rotates and drives the meshing gear 2 63 to rotate, so that the gear 2 63 drives the inner conduit 5 to rotate, so that the inner conduit 5 rotates slowly in the outer tube 4, and the inner wall of the tube body 51 is dynamically rubbed against the fixed concrete. As the internal concrete solidifies, the outer wall of the formed pile and the inner conduit 5 are kept relatively peeled off, and the external lifting mechanism is started to quickly lift the outer tube 4 and the inner conduit 5 out of the water, completing the separation and removal of materials, moving the position and carrying out the pouring operation of the next group of pile foundations.

[0024] Firstly, by utilizing the sleeve assembly effect of the outer tube 4 and the inner conduit 5, a driving component 6 is added and arranged on the outside of the outer tube 4. After the water accumulated in the space between the outer tube 4 and the inner conduit 5 is drained and sealed, the driving component 6 is further started and the inner conduit 5 is driven to rotate slowly in the outer tube 4. During the solidification of the internal concrete, the inner conduit 5 on the outside of the concrete is always in dynamic contact with the concrete. With the complete solidification, the inner wall of the inner conduit 5 is kept separated from the concrete to avoid adhesion, thereby improving the subsequent separation effect of the inner conduit 5 from the formed concrete pile, reducing strain, improving the continuous pouring efficiency, and achieving a good comprehensive use effect.

The water outlet 53 is used to guide the water flow to be discharged from the inner conduit 5.

[0030] By utilizing the driving component 6 to provide driving force and cooperating with the meshing rotation of gear 1 62 and gear 2 63, the inner conduit 5 can rotate slowly in the outer tube 4. After the concrete is poured, dynamic contact is utilized to reduce adhesion of the concrete after solidification and improve the subsequent separation effect.

[0031] Among them, the air supply component 10 includes an air pump 101, an arc-shaped distribution frame 102 and an air pipe 103.

[0032] By utilizing the air supply component 10 to provide pressurized air and utilizing the effect of conducting pressurized air, the action of the processing component 7 is realized, and the accumulated water is further drained to prevent backflow. The pressurized air is further utilized to complete the movement of the deflation component 11, and the drainage ball 8 is punctured and collapsed.

[0033] Among them, the outer surface of the outer tube 4 is respectively provided with a drain port 12, an adapting groove 13 and a connecting port 14. The drain port 12 is symmetrically opened on the outside of the outer tube 4, the adapting groove 13 is adapted to the gear 1 62, one end of the connecting port 14 is connected to the arc-shaped distribution frame 102, and the other end is connected to the processing component 7.

[0035] Among them, the deflation component 11 includes a conducting cavity 111, a push block 112, a ejector pin 113 and a second spring 114. The conducting cavity 111 is opened inside the movable arc plate 72, and one end is connected to the adapter 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 conducting cavity 111, and the other end is fixedly connected to the push block 112. The ejector pin 113 is fixedly connected to the end surface of the push block 112 and is located in the annular groove 52. There are two groups of processing components 7, and the two groups of processing components 7 are symmetrically distributed inside the outer tube 4. The spacing value of adjacent fixed arc plates 71 is less than the arc length value of the movable arc plate 72.

[0036] The deflation component 11 achieves shape collapse by puncturing the thick-walled drainage ball 8 that is filled with gas and expands, thereby reducing the structural impact on the pile during landfill.

[0037] The working principle and use process of the present invention are as follows: when in use, the lifting mechanism connected to the outside of the mounting frame 1 is started to drive the mounting frame 1 and the outer tube 4 to move synchronously, and the mounting frame 1 and the outer tube 4 are inserted into the water upward and downward along the water surface, and the outer tube 4 and the inner conduit 5 are synchronously moved to the base of the pile foundation, and the drainage ball 8 is put into the inside of the tube body 51 of the inner conduit 5, and the drainage ball 8 floats inside the tube body 51, and one end of the steel cage to be poured is inserted into the inside of the inner conduit 5, and the bottom of the steel cage is positioned on the top of the positioning arc plate 9. An external pushing device is used to push the steel cage downward in the inner conduit 5, squeeze the drainage ball 8 to move downward along the inside of the tube body 51, and push the water flow inside the tube body 51 to be squeezed along the water outlet 53 to the space between the outer tube 4 and the inner conduit 5, and as it is continuously pushed, the drainage ball 8 is pushed downward along the inside of the tube body 51 to push the water flow inside the tube body 51 to the space between the outer tube 4 and the inner conduit 5. The inner water flows upward along the gap between the outer tube 4 and the inner conduit 5 and is discharged through the drain port 12. The steel cage moves and is inserted into the inner conduit 5 to complete the drainage process. Then the push part 3 is started to push the pouring port 2 to move to the top of the inner conduit 5. The external concrete release pipeline puts concrete into the pouring port 2 and continuously pours it into the inner conduit 5 to perform the pouring operation. The air supply component 10 is started, and the air pump 101 inputs the pressurized air into the connecting port 14 through the air pipe 103 and the arc distribution frame 102, and inputs the pressurized air into the adapting cavity 74 of the processing component 7 along the connecting port 14. As the air pressure in the adapting cavity 74 increases, the movable arc plate 72 is pushed to slide along the inside of the adapting cavity 74 and along the arc estimation The plan pushes and stretches the spring 1 73 while the outer large end of the movable arc plate 72 further squeezes the liquid in the two groups of treatment components 7. With the synchronous squeezing of the two groups of movable arc plates 72, all the water between the inner conduit 5 and the outer tube 4 is squeezed out, and the air release component 11 on the side of the movable arc plate 72 is driven to rotate along the annular groove 52 to the water outlet 53. With the continuous supply of pressurized air, the air pressure inside the adaptation cavity 74 continues to increase and is continuously filled into the conduction cavity 111.

While the pulling spring 114 is stretched, the ejector pin 113 is driven to move along the water outlet 53. As the ejector pin 113 continuously moves and contacts the drainage ball 8, the drainage ball 8 is squeezed by the sharp edge.

As the internal concrete solidifies, the outer wall of the formed pile and the inner guide tube 5 are kept relatively peeled off, and the external lifting mechanism is started to quickly lift the outer tube 4 and the inner guide tube 5 out of the water, completing the separation and material removal, moving the position and carrying out the pouring operation of the next group of pile foundations.
