[0001] This invention relates to the field of concrete reinforcement technology, and in particular to a method for integrated construction of pile foundations and concrete casing. Background Technology

[0002] The pile body of the pile foundation is completely buried in the soil, and the bottom surface of the pile cap is in contact with the soil to support and reinforce the building foundation. It is commonly used in building construction. During the installation of underwater pile foundation, it is necessary to use concrete caissons for auxiliary construction. When lowering the concrete caisson, the construction personnel need to observe and correct it in real time to ensure that the concrete caisson is accurately positioned.

[0025] like Figure 1 and Figure 8As shown in the embodiments of the present invention, a method for integrated construction of pile foundation and concrete casing is provided, the method comprising the following steps: S1: The operator aligns the construction device with the pile foundation construction site and starts the motor to drive the closing assembly to close the movable sleeve. S2: The motor-driven lifting assembly places the movable sleeve at the pile foundation construction site. When the motor-driven lifting assembly places the movable sleeve, it drives the fixed support assembly to provide auxiliary support for the movable sleeve. S3: The operator pours concrete into the movable sleeve. After the concrete pile foundation has solidified, the reverse drive motor is used to remove the movable sleeve.

[0026] like Figure 1 and Figure 2As shown, the construction device in step S1 includes a fixed bracket 1, a motor 2 is installed at one edge of the fixed bracket 1, a helical gear 3 is rotatably connected to the bottom of the motor 2, a helical gear set 4 is meshed on one side of the helical gear 3, a spur gear 5 is rotatably connected to the bottom of the helical gear 3, a closing component 6 is installed on one side of the helical gear set 4, and the closing component 6 is used to close the movable sleeve 10; a driving component 7 is installed on one side of the spur gear 5, and the driving component 7 is used to drive the lifting component 8 and the fixed support component 9; the lifting component 8 is installed inside the driving component 7. The lifting component 8 is used to lift the movable sleeve 10; the fixed support component 9 is located at the bottom edge of the drive component 7 and is used to provide fixed support for the movable sleeve 10; the movable sleeve 10 is provided at the bottom of the drive component 7, and a telescopic rod 11 is provided on the outer surface of the middle part of the movable sleeve 10. In real-time use, after the operator places the construction device at the construction position where the pile foundation needs to be installed, the motor 2 is started. The motor 2 first drives the closing component 6 to close the movable sleeve 10 through the helical gear set 4. At the same time as the movable sleeve 10 closes, the drive component 7 drives the... The lifting assembly 8 operates, placing the combined movable sleeve 10 at the construction site. Simultaneously, the drive assembly 7 drives the fixed support assembly 9 to operate, working in conjunction with the lifting assembly 8 to support and fix the movable sleeve 10. A closing assembly 6 is used to close the movable sleeve 10. After the poured concrete has solidified, the closing assembly 6 expands the movable sleeve 10 around its perimeter, preventing damage to the concrete surface during removal. The lifting assembly 8 raises and lowers the movable sleeve 10 a certain distance, while the closing assembly 6 minimizes the contact area between the movable sleeve 10 and the concrete surface, preventing damage to the overall strength of the solidified concrete. The fixed support assembly 9, utilizing the characteristics of liquid pressure transmission, provides auxiliary support to the movable sleeve 10 when it is lowered by the lifting assembly 8. The fixed support assembly 9 provides horizontal support to the movable sleeve 10 based on different height differences at the construction site, and also fixes the movable sleeve 10 around its perimeter, further improving the fixing effect and increasing the processing accuracy of the pile foundation.

[0027] like Figure 3 and Figure 8As shown, the closing assembly 6 includes an adjusting disc 61. A first pin 62 is rotatably mounted at the bottom of the adjusting disc 61. An adjusting rod 63 is fixedly mounted at one end of the first pin 62. A second pin 64 is rotatably sleeved at the bottom of the adjusting rod 63. The bottom end of the second pin 64 is rotatably connected to the top of the movable sleeve 10. The second pins 64 are arranged in a circular array at the top of the movable sleeve 10, with an included angle of 90 degrees between them. A limit rod 65 is provided at the top of the adjusting disc 61. A rack 66 is fixedly mounted at the top of the limit rod 65. A telescopic rod 67 is elastically mounted at the top of the rack 66. The top of the telescopic rod 67 is elastically connected to the inner wall of the fixed bracket 1. A spur gear 68 is meshed on one side of the rack 66. The spur gear 68 is rotatably mounted on the top of the inner wall of the fixed bracket 1. A helical gear 69 is rotatably connected to one end of the spur gear 68. The helical gear 69 meshes with one end of the helical gear set 4. In real-time use, the motor 2 drives the helical gear. When helical gear 13 rotates, it drives helical gear set 4 on one side to mesh and rotate. Helical gear set 4 drives spur gear 268 through helical gear 269 to mesh and rotate. Spur gear 268 drives rack 166 on one side to mesh and rotate. As rack 166 moves upward, it drives limit rod 65 to slide. Under the sliding action of rack 166, it pulls adjusting plate 61 to move upward. Adjusting plate 61 drives adjusting rod 63 to move upward first through pin 162. Adjusting rod 63 pulls movable sleeve 10 through pin 264, so that movable sleeve 10 contracts proportionally as a whole, realizing the overall closing operation of movable sleeve 10. By setting adjusting rod 63, pin 162 and pin 264, the vertical force generated by rack 166 is converted into a horizontal force. The overall closing operation of movable sleeve 10 is realized by the up and down sliding of rack 16. The mechanism is simple and can flexibly switch the closed state of movable sleeve 10 during construction.

[0028] like Figure 4 , Figure 5 and Figure 7As shown, the drive assembly 7 includes a fixed chassis 71 with a cavity inside. A rotating ring 72 is rotatably fitted on the outer surface of the fixed chassis 71. A tooth 74 is provided at the top edge of the rotating ring 72, and a toothed ring 73 is provided at the bottom of the inner wall of the rotating ring 72. The toothed ring 73 meshes with a spur gear 5. A toothed ring 75 is provided at the bottom edge of the rotating ring 72. An opening 76 is provided in the middle of one side of the fixed chassis 71. In real-time use, while the motor 2 drives the helical gear 3 to rotate, the helical gear 3 drives the spur gear 5 at the bottom to engage... The gear 5 drives the gear ring 73 on one side to rotate synchronously. Under the meshing action of the gear ring 73, the rotating ring 72 rotates on the outer surface of the fixed chassis 71. At the same time, the rotating ring 72 drives the meshing gear 74 and the gear ring 75 to rotate. By setting the gear ring 73 to drive the rotating ring 72 to rotate, the meshing gear 74 and the gear ring 75 set on the rotating ring 72 drive the lifting component 8 and the fixed support component 9 respectively, so as to realize the synchronous operation of the lifting component 8 and the fixed support component 9 and ensure the processing accuracy during construction.

[0029] like Figure 4 and Figure 5 As shown, the lifting assembly 8 includes a helical gear 3 81, which is nested and rotatably mounted on the outer surface of the fixed chassis 71. The helical gear 3 81 meshes with a gear 74. One end of the helical gear 3 81 is connected to a helical gear 4 82, which is rotatably mounted at the bottom end of the cavity inside the fixed chassis 71. A helical gear 5 83 is meshed and rotatably mounted on one side of the helical gear 4 82. One end of the helical gear 5 83 is rotatably connected to a spur gear 3 84, which is rotatably mounted at the edge of the inner wall of the opening 76. A rack 2 85 is rotatably meshed on one side of the spur gear 3 84. A limit ring 86 is fixedly installed on one end of the rack 2 85. The inner wall surface of the limit ring 86 is connected to the telescopic rod 1 11. The rack 2 85 is arranged in a circumferential array on the outer surface of the limit ring 86. The included angle between the gears is set to 90 degrees. In real-time use, the gear 74 rotates while driving the helical gear 3 81 to mesh and rotate. The helical gear 3 81 drives the helical gear 4 82 to rotate synchronously. The helical gear 4 82 drives the spur gear 3 84 to mesh and rotate through the helical gear 5 83 on one side. The spur gear 3 84 drives the rack 2 85 on one side to mesh and move. Under the action of the rack 2 85, the limiting ring 86 moves downward as a whole. The limiting ring 86 places the movable sleeve 10 at the construction site through the telescopic rod 11. By setting the cooperation of the helical gear 3 81 and the rack 2 85, the lowering and raising operations of the movable sleeve 10 are realized. The mechanism is simple. At the same time, the closing component 6 is used to open the movable sleeve 10 to avoid damage to the concrete surface after solidification.

[0030] like Figure 6 and Figure 7As shown, the fixed support assembly 9 includes a liquid storage tank 91, which is fixedly installed at the bottom edge of the fixed base 71. A screw 92 is rotatably installed inside the cavity of the liquid storage tank 91. A spur gear 93 is provided at the top of the screw 92, and the spur gear 93 meshes with a gear ring 75. A piston disc 920 is threaded onto the outer surface of the screw 92, and the piston disc 920 slides against the inner wall of the liquid storage tank 91. The liquid storage tanks 91 are arranged in a circumferential array at the bottom of the fixed base 71. The included angle is set to 60 degrees. A liquid inlet tank 94 is connected to the bottom of the liquid storage tank 91. A spring 95 is elastically installed at the bottom of the inner wall of the liquid inlet tank 94. A fixing block 96 is elastically connected to one end of the spring 95. The fixing block 96 slides elastically against the inner wall of the liquid inlet tank 94. A belt assembly 97 is rotatably sleeved on the upper outer surface of the screw 92. A rotary drill bit 98 is rotatably sleeved on the inner wall of one end of the belt assembly 97. The rotary drill bit 98 is rotatably positioned at the top edge of the liquid storage tank 91. In actual use, the gear ring 2 75 drives the flat gear 4 9. 3. The meshing rotation of the gear 93 drives the screw 92 to rotate within the cavity of the storage tank 91, causing the piston disc 920, threaded onto the screw 92, to slide and compress the oil inside the storage tank 91. This compresses the oil stored in the storage tank 91 into the inlet tank 94. Under the compressive action of the piston disc 920, the oil in the inlet tank 94 compresses the fixing block 96, pushing the fixing block 96 out of the inlet tank 94, thus supporting the ground at the construction site. Simultaneously, the screw 92 rotates via the belt assembly 97. The rotary drill bit 98 rotates on one side, and the rotation of the rotary drill bit 98 is used to fix the ground at the construction site. By setting up the liquid inlet tank 94, the fixing block 96 is pushed out of the liquid inlet tank 94 by utilizing the characteristics of liquid pressure transmission, so as to achieve the supporting effect of the movable sleeve 10. At the same time, by setting up the rotary drill bit 98, together with the fixing block 96, the fixing effect is achieved while supporting. The secondary fixing improves the supporting effect of the movable sleeve 10 and ensures the processing accuracy of the movable sleeve 10 when pouring concrete.

[0031] The technical solution provided by this invention, by setting a closing component, performs a closing operation during concrete pouring and after solidification. At the same time, in conjunction with the lifting operation of the lifting component, when the movable sleeve is removed after construction, it avoids the movable sleeve from sliding on the concrete surface for a long time, which would damage the concrete surface. The lifting component also minimizes the contact area between the movable sleeve and the concrete surface, thus affecting the overall strength of the concrete after solidification and avoiding repeated construction that would increase construction costs.

[0032] By setting up a fixed support assembly, the movable sleeve is fixedly supported when it is lowered, ensuring the horizontal accuracy of the movable sleeve during placement and the processing accuracy during concrete pouring. By utilizing the characteristics of liquid pressure transmission, the support effect is achieved by pushing out the fixed blocks. The array of fixed blocks can adapt to different height differences on the underwater ground, making the movable sleeve suitable for underwater placement. In conjunction with the rotary drill bit, synchronous rotation and fixation are performed to achieve secondary fixation and improve the fixation effect of the movable sleeve.
