A stable installation pile foundation structure for building construction

Abstract

The present invention provides a stable pile foundation structure for construction, which relates to the technical field of pile foundation installation structures, including an installation platform, a fixing mechanism, a locking mechanism and a maintaining mechanism. The cooperation of a level sensor and a small level gauge is used to ensure that a support plate is completely in contact with the horizontal surface. The telescopic ends of multiple electric telescopic rods are inserted into deep soil, and cement slurry is injected into the soil through grouting holes to strengthen the connection between the installation platform and the soil and enhance the bearing capacity of the installation platform. The double-sided gear and the gear ring are driven by a motor to rotate simultaneously, thereby driving the first tooth plate and the second tooth plate to slide. The sliding of the first tooth plate and the second tooth plate allows the wheel and the arc bar to fix the steel pipe at the same time. The wheel and the arc bar are used to simultaneously fix the pile foundation steel pipe in two planes and in multiple directions, thereby ensuring the accuracy of the pile foundation. The position of the first tooth plate is limited by the maintaining mechanism to ensure that the first tooth plate will not move during the hammering process, thereby ensuring the stability and accuracy of the pile driving process.

Description

[0003] Therefore, the pile foundation structure can be said to be the basic part used to support buildings or structures in construction projects. With the development of construction technology and engineering needs, the requirements for pile foundation structures are becoming higher and higher, especially in complex geological conditions, high-rise and super-high-rise buildings, and large-scale infrastructure construction.

[0004] When the construction site is a soft soil foundation, usually the pipe sinking method is adopted. This kind of pile foundation usually uses vibration or hammering to sink the steel pipe into the ground, and then pour concrete into the pipe. After that, the steel pipe is pulled out and the concrete pile is left. However, due to the soft soil, it is difficult to provide a reference surface and fix the position of the steel pipe. At the same time, the steel pipe is easy to tilt during hammering, and there is already a certain degree of tilt during pouring, which leads to unstable foundation. Summary of the invention

[0018] Beneficial effects of the present invention:

[0019] 1. The stable installation pile foundation structure for this building construction is first installed on the ground through a cone column. The horizontal sensor on the support plate is used to feedback the situation of the small level to ensure that the support plate is completely in contact with the horizontal surface. After the contact, the telescopic ends of multiple electric telescopic rods are inserted into the deep soil, and then cement slurry is injected into the surrounding soil through the grouting holes to further strengthen the connection between the installation platform and the soil, enhance the bearing capacity of the installation platform, thereby ensuring that the installation platform provides sufficient support for the pile foundation and ensures the accuracy of piling.

[0020] 2. The stable installation pile foundation structure for construction uses two sets of indentation components to fix the position of the pile foundation, and the double-sided gear and the gear ring are driven by a motor to rotate simultaneously, thereby driving the first tooth plate and the second tooth plate to slide, and the sliding of the first tooth plate and the second tooth plate enables the push wheel and the arc bar to fix the steel pipe at the same time.

[0021] 3. The stable installation pile foundation structure for construction uses a maintaining mechanism to permanently fix the steel pipe. When the motor is running, the first magnetic block is magnetic and attracts the second magnetic block to compress the spring. The card block is received into the third installation groove, and the first tooth plate can move normally to fix the pile foundation steel pipe. When the motor stops, the magnetism of the first magnetic block disappears. Due to the elastic force of the spring, the card block moves up instantly to limit the movement of the first tooth plate, preventing the hammering force from being too large, causing the first tooth plate to move, thereby ensuring the stability of the steel pipe during the piling process.

Since the connecting rod 34 connects the first gear 33 and the sixth gear 36, and the sixth gear 36 is meshed with the gear ring 321, the double-sided gear 311 and the gear ring 321 can be rotated simultaneously through the motor 37.

[0045] The first locking units 313 are provided with four, and the four first locking units 313 include a bearing 3131, a third gear 3132, a first tooth plate 3133, a slide plate 3134, a first slide rail 3135 and a stop wheel 3136. The bottom of the bearing 3131 is fixedly connected to the fixed plate 13, the top of the bearing 3131 is rotatably connected to the third gear 3132, the third gear 3132 is meshed with the first tooth plate 3133, the inner wall of one end of the first tooth plate 3133 is rotatably connected to the stop wheel 3136, the bottom of the first tooth plate 3133 is fixedly provided with a slide plate 3134, the slide plate 3134 is slidably connected to the first slide rail 3135, and the bottom of the first slide rail 3135 is fixedly connected to the fixed plate 13;

At the same time, the gear ring 321 is used to drive the fourth gear 3241 to rotate, and the fourth gear 3241 drives the fifth gear 3242 to rotate. Since the fifth gear 3242 is meshed with the second tooth plate 3243, the second tooth plate 3243 moves accordingly, and the four arc bars 3246 fix the pile foundation steel pipe at the same time.

Example 2

[0048] Reference Figure 5 and Fig. 9 This embodiment is based on the previous embodiment, and differs from the previous embodiment in that.

[0049] refer to Figure 5 A first mounting groove 121 and a second mounting hole 122 are opened in the middle of the ring plate 12 . A ring rail 322 is installed in the first mounting groove 121 , and the second mounting hole 122 is used to install a second locking unit 324 .

[0052] In the preferred embodiment of the present invention, when the motor 37 is running, the first magnetic block 41 is magnetic, attracting the second magnetic block 43 to compress the spring 42, thereby receiving the clamping block 44 into the third mounting groove 134, and the first tooth plate 3133 can move normally to fix the pile foundation steel pipe. When the motor 37 stops, the magnetism of the first magnetic block 41 disappears, and due to the elastic force of the spring 42, the clamping block 44 is rebounded and moves upward instantly, thereby limiting the movement of the first tooth plate 3133, preventing excessive hammering force from causing the first tooth plate 3133 to move, thereby ensuring the stability and accuracy of the pile foundation steel pipe during the piling process.

[0053] The working principle of the present invention is as follows: during installation, the small level 113 and the level sensor 114 on the support plate 11 accurately reflect the horizontal position of the mounting platform 1, ensuring that the mounting platform 1 can be completely horizontal and provide a reference surface for the pile foundation steel pipe. When the mounting platform 1 is completely horizontal, the mounting platform 1 is fixed by the cone column 21. After fixation, the telescopic end of the electric telescopic rod 23 moves and is inserted into the surrounding soil to enhance the stability of the mounting platform 1. Then, cement slurry is injected into the grouting column 22 through the grouting hole 131 on the fixing plate 13, and the cement slurry is driven into the soil through the first introduction hole 231 and the second introduction hole 212. The cement slurry is used to further strengthen the connection between the mounting platform 1 and the soil, enhance the bearing capacity of the mounting platform 1, and ensure that the mounting platform 1 can provide sufficient supporting force for the pile foundation steel pipe, thereby ensuring the accuracy of piling. After the mounting platform 1 is completely fixed, the pile foundation steel pipe is placed in the middle of the ring plate 12.

[0054] Start the motor 37, the first magnetic block 41 is magnetic, attracting the second magnetic block 43 to compress the spring 42, so that the block 44 is received in the third mounting groove 134, ensuring that the first tooth plate 3133 can move normally, the motor 37 drives the second gear 35 to rotate, the second gear 35 drives the first gear 33 and the sixth gear 36 to rotate, the first gear 33 drives the double-sided gear 311 to rotate, the sixth gear 36 drives the gear ring 321 to rotate, the double-sided gear 311 drives the four third gears 3132 to rotate, the third gear 3132 drives the first tooth plate 3133 to move, so that the wheel 3136 is close to the pile foundation steel pipe for fixation, and the gear ring 321 drives the fourth gear 3241 to rotate. The fourth gear 3241 drives the fifth gear 3242 to rotate, and the fifth gear 3242 drives the second tooth plate 3243 to move, so that the arc bar 3246 is close to the pile foundation steel pipe for fixing. The pile foundation steel pipe is simultaneously fixed in two planes and multiple directions by the anti-wheel 3136 and the arc bar 3246 to ensure the accuracy of the pile foundation. After the anti-wheel 3136 and the arc bar 3246 fix the pile foundation steel pipe, the motor 37 stops and the first magnetic block 41 is demagnetized. Due to the elastic force of the spring 42, the block 44 rebounds and moves up instantly, limiting the movement of the first tooth plate 3133, ensuring that the first tooth plate 3133 does not move during the hammering process, thereby ensuring the stability and accuracy of the pile foundation steel pipe during the piling process.
