Technical Field
[0001] The present invention relates to the technical field of pile foundation reinforcement, and particularly to an offshore pile foundation reinforcement device. Background Art
[0002] Offshore pile foundation reinforcement refers to the reinforcement treatment of pile foundations used in offshore projects to improve the bearing capacity, stability and durability of the pile foundations, and ensure the safety and reliability of offshore structures. Offshore pile foundations are widely used in offshore projects such as oil platforms, wind power platforms, and ocean bridges. Due to the complex marine environment, the pile foundations may be affected by various factors such as wind waves, tides, and corrosion. Therefore, it is very necessary to carry out pile foundation reinforcement. The current pile foundation processing methods generally use mortar or other chemical raw materials for filling to form a tight connection with the surrounding geological structure. However, the current processing devices can only perform simple reinforcement operations, with relatively single functions and limited contact areas with the geological structure, and there is no further optimization. Based on this, the present invention proposes a processing device that can further position and reinforce the pile foundation, increase the contact area between the mortar and the surrounding geological structure, and enhance the reinforcement effect.

[0030] Operating principle: During reinforcement, the pile foundation 2 is buried in the ground, and subsequent mortar filling is carried out according to the construction process. Specifically, the pile rod 1 is installed inside the pile foundation 2, and the positioning cylinders 6 on the pile rod 1 correspond to the docking cylinders 7 respectively. The movement of the mating shaft 8 is controlled by the actuator, so that the mating shaft 8 cooperates with the positioning cylinder 6 to achieve positioning and reinforcement. Specifically, the feeding mating part 27 is put in for mortar feeding, and it can also cooperate with the mating part 9. The radial position thereof is controlled by controlling the electric cylinder 18 to control the mating shaft 8, that is, by controlling the movement of the feeding moving pipe 26, and the feeding mating part 27 extends through the groove at the top of the pile foundation 2 into the pile foundation 2 to achieve cooperation with the mating part 9.
[0031] During mortar filling, the mortar is transported by the transfer pump 19 and is transported and put in through the telescopic connecting pipe 25, the feeding moving pipe 26 and the feeding mating part 27. By the operation of the first motor 11, the first lead screw 10 rotates, and the height of the sliding seat 13 can be controlled, and then the moving depth of the execution cylinder 20 can be controlled. By the operation of the second motor 14, the rotating ring 17 can be rotated, that is, the orientation of the execution cylinder 20 is adjusted.
[0032] During filling, the execution cylinder 20 cooperates with the corresponding outer filling cylinder 4 or inner filling cylinder 5. The execution cylinder 20 enters the inside of the outer filling cylinder 4 or the inner filling cylinder 5. The perforation operation can be carried out first through the radial perforation mechanism. Specifically, the pile foundation 2 is buried in the ground. The outer filling cylinder 4 contacts the soil structure around the ground. The inner filling cylinder 5 is located inside the pile foundation 2, and the bottom end of the inner filling cylinder 5 also contacts the soil structure of the ground. The execution cylinder 20 can be moved to the inside of the outer filling cylinder 4 and the inner filling cylinder 5, and drilling can be carried out at different positions through height adjustment to increase the contact area between the subsequent mortar and the soil structure, and finally a tighter structure is formed.
[0033] Specifically, when the drilling motor 36 operates, the drilling turntable 32 rotates, causing the radial lead screw 34 to rotate. In cooperation with the gear 39 and the first spring 30, they also rotate, and the push plate 38 moves, which can push the cooperating rotating shaft 41 to move, that is, the drilling shaft 40 moves outward. The drilling shaft 40 passes through the hole positions on the outer filling cylinder 4 and the inner filling cylinder 5 to perform drilling operations on the external geological structure. When performing mortar filling, the execution cylinder 20 cooperates with the inner sides of the outer filling cylinder 4 and the inner filling cylinder 5, and the mortar enters the outer filling cylinder 4 and the inner filling cylinder 5. For the outer filling cylinder 4, the mortar fills the inside of the outer filling cylinder 4 and flows through the hole positions to the outer geological structure. At the same time, the mortar is transmitted to the docking cylinder 7 to block the cooperating shaft 8. When discharging the mortar, the third motor 21 operates, and the third lead screw 22 rotates, causing the control slide 24 to move. When the control slide 24 moves, the extrusion arc plate 28 contacts and pushes the radial shaft 29. The radial shaft 29 reciprocates telescopically, and one end of it reciprocally contacts the inner wall of the execution cylinder 20, which can cause the execution cylinder 20 to vibrate. The execution cylinder 20 cooperates with the outer filling cylinder 4 and the inner filling cylinder 5, and the vibration can be transmitted, that is, when discharging the mortar, the mortar can be vibrated to make the mortar filling more compact. Further, by controlling the reciprocating movement of the control slide 24, the discharging moving pipe 26 also moves, reciprocating up and down, which is beneficial to shake off the mortar adhering to the inside of the discharging moving pipe 26 and reduce the residue. By controlling the electric cylinder 18, the radial position of the execution cylinder 20 is controlled, and by rotating the rotating ring 17, the orientation of the execution cylinder 20 is controlled to perform mortar filling on different ranges of the outer filling cylinder 4 and the inner filling cylinder 5.
