Description

Technical Field

[0001] The present invention relates to the technical field of foundation pile construction, and in particular to an implantable pipe pile construction device and a construction method thereof. Background Art

[0002] Implantable pipe piles are a new type of pile foundation technology. Prefabricated pipe piles with sufficient strength are prefabricated in a factory, transported to the construction site, and drilled at the desired location. Cement mortar is then poured into the holes. Once the mortar is poured, the piles can be sunk directly, significantly reducing construction time. This technology leverages the advantages of prefabricated pipe piles to quickly create foundation piles with sufficient bearing capacity. This effectively reduces construction disturbance to the foundation, shortens the pile foundation maintenance cycle, improves construction efficiency, and enhances the industrialization of the foundation.

[0003] However, when installing pipe piles, they are first grouting and then inserting the pipe piles. During installation, the verticality and installation position of the pipe are difficult to control and are also very difficult to adjust. During installation, it is necessary to detect the position and verticality information while installing and make adjustments. When the bottom of the pipe pile touches the bottom, if it is found that the verticality and installation position deviation of the pipe pile exceed the standard, the pipe pile can only be pulled out and then operated again. It is impossible to make it vertical by pushing the upper part of the pipe pile, because once the upper part of the pipe pile is pushed, the position of the upper part of the pipe pile will change, which will cause the position of the pipe pile to be incorrect, making the installation operation of the pipe pile very troublesome and difficult to control.

By injecting hydraulic oil into the sliding cavity of the piston head 11 through the oil circuit 13, the clamping guide assembly 7 can be moved toward the central axis position of the casing 6. When a pipe pile 50 is inserted into the casing 6, injecting hydraulic oil into the sliding cavity of the piston head 11 can enable the clamping guide assembly 7 to clamp the pipe pile 50. During the construction of the pipe pile 50, the pipe pile 50 is hoisted so that a section of the bottom of the pipe pile 50 is inserted into the casing 6. The multiple clamping guide assemblies 7 are controlled to clamp the pipe pile 50. The multiple pipe pile guide wheels 701 on the clamping plate 702 simultaneously abut against the pipe pile 50 to keep the pipe pile 50 parallel to the clamping plate 702 and the casing 6. The verticality of the pipe pile 50 is further controlled by controlling the verticality of the casing 6 through four adjusting hydraulic rods 8.

[0044] In this embodiment, a pile driving device is fixedly provided at the bottom of the casing 6, and the pile driving device includes a driving wheel 10. The driving wheel 10 is rotatably provided on the driving frame, and a driving motor for driving the driving wheel 10 is fixed on the driving frame. After the driving wheel 10 contacts the pipe pile 50, the friction force can drive the pipe pile 50 to complete the pile driving stably and quickly.

[0045] In this embodiment, the pipe pile lifting fixture 1 includes a core rod assembly and a hanger clamping portion. The upper end of the core rod assembly is fixed at the axis of the hanger clamping portion. The hanger clamping portion is used to clamp the outer side of the top of the pipe pile 50. The core rod assembly is inserted into the pipe pile 50 from the top of the pipe pile 50, and is used to expand and support the pipe pile 50 inside the pipe pile 50. The pipe pile 50 is clamped and supported by the core rod assembly and the hanger clamping portion at the same time, so that the pipe pile 50 can be stably clamped and fixed.

[0046] Furthermore, the clamping part of the hanger includes a clamping claw column 17, a clamping claw driving rod 15 and a plurality of clamping claws 16 evenly distributed on the clamping claw column 17. The clamping claw 16 is fixed to one end of the clamping claw driving rod 15. A thread is provided at a place on the clamping claw driving rod 15. The clamping claw driving rod 15 is provided with a clamping driving disk 14 that cooperates with its thread. The clamping driving disk 14 is rotatably arranged in the clamping claw column 17. By rotating the clamping driving disk 14, the opening and closing of each clamping claw 16 can be controlled at the same time, thereby completing the clamping of the top of the pipe pile 50.

[0047] It should be noted that the structure in which the clamping jaws 16 drive the disc to drive the clamping jaws 16 to complete clamping can refer to the structure of a chuck.

[0048] In this embodiment, the core rod assembly includes a first core shaft portion 18, a second core shaft portion 19, an expansion strip 21 and a wedge block 22. The second core shaft portion 19 is slidably provided in the first core shaft portion 18, and the second core shaft portion 19 is coaxial with the second core shaft portion 19. A thread is provided at the top of the second core shaft portion 19, and the second core shaft portion 19 is threadedly connected to the locking nut 20 at the thread.

The second core shaft portion 19 is fixed with a plurality of wedge blocks 22 at the bottom end. The wedge block 22 is provided with an inclined surface, and the expansion strip 21 is also provided with an inclined surface that cooperates with the wedge block 22 at a position close to the wedge block 22. The wedge block 22 and the inclined surfaces on the expansion strip 21 are in contact with each other. Through the two inclined surfaces, when the wedge block 22 moves upward, the wedge block 22 can drive the expansion strip 21 to expand, so that the core rod assembly fixes the inside of the pipe pile 50. When the inside of the pipe pile 50 is expanded and fixed, it is completed by rotating the locking nut 20. When the locking nut 20 is rotated, the locking nut 20 drives the second core shaft part 19 to move upward, and the wedge block 22 on the second core shaft part 19 pushes the expansion strip 21 to expand the inner wall of the pipe pile 50 so that the inner wall of the pipe pile 50 is fixed to the core rod assembly.

[0049] In this embodiment, the diameter of the clamping claw column 17 is the same as the diameter of the pipe pile 50, and the width of the clamping claw 16 and the clamping claw driving rod 15 are both smaller than the gap width between two adjacent clamping guide assemblies 7. During pile sinking, when the top of the pipe pile 50 has dropped below the clamping guide assembly 7, the clamping guide assembly 7 can still control the verticality of the pipe pile 50 by clamping the position of the clamping claw column 17. At the same time, the core rod assembly is used to effectively ensure that the clamping claw column 17 is parallel to the pipe pile 50, thereby further ensuring the verticality of the pipe pile 50. It can effectively ensure that the pipe pile 50 can maintain a high verticality from the beginning of pile sinking to the bottoming out, thereby improving construction accuracy.

[0050] Advantageously, the drilling device of this embodiment is also provided with a verticality control system, which includes a verticality detection module and a verticality correction module. The verticality detection module includes a verticality sensor, one of which is arranged in the core shaft and the other is arranged on the casing 6. The verticality correction module controls the verticality state of the casing 6 by feeding back the verticality information of the verticality sensor.

[0051] It should be noted that the verticality sensor may be a combination of two or more tilt sensors, and the verticality information can be accurately calculated by fitting the data of each tilt sensor.
