[0002] Bored piles are a widely used foundation method in projects such as offshore platforms and cross-sea bridges. However, the offshore construction environment is highly dynamic, has complex geological conditions, and is highly corrosive.

Wind, waves, currents, and tides at sea cause the construction platform to shift dynamically. Traditional mechanical guidance mechanisms struggle to correct drill pipe verticality in real time, which can easily lead to pile hole deviation. Existing technologies often rely on large fixed platforms or mooring systems, which are costly and sensitive to water depth, making them unsuitable for deepwater or soft soil scenarios.

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] See also Figure 1-13 , the present invention provides a technical solution: a bored pile device adapted to complex offshore environments, comprising a platform mechanism, a drilling mechanism, and a bored pile mechanism;

[0032] The platform mechanism includes a main body 1, which is composed of two crawler assemblies 2 and a base 3. A chassis 6 is provided between the two crawler assemblies 2. The crawler assembly 2 is connected to the chassis 6. The crawler assembly 2 is a prior art and will not be described in detail in this embodiment.

[0033] An outer support shell 4 is symmetrically installed between the two crawler assemblies 2. The outer support shell 4 is connected to the chassis 6. The base 3 stands vertically on the central axis of the outer support shell 4. A hydraulic lifting assembly 5 is installed at the bottom of the base 3. The bottom of the hydraulic lifting assembly 5 is installed on the top of the outer support shell 4. The base 3 is driven to move up and down by controlling the operation of the hydraulic lifting assembly 5. By controlling the hydraulic lifting assembly 5 to rise, the base 3 is driven to rise, and then the entire base 3, the drilling mechanism, and the cast-in-place pile mechanism are driven to rise, thereby preventing water from entering the control room.

[0034] GNSS receivers are installed at the four corners of the top of the base 3. The data obtained by the GNSS receivers is transmitted to the central controller via pipelines or Bluetooth. The central controller is set in the internal control room of the base 3;

[0035] A hydraulic balance component and a pneumatic balance component are provided at the bottom of the main body 1;

[0036] A hydraulic balancing assembly is set on the inside of the track assembly 2, and the hydraulic balancing assembly includes a support block 7 fixedly mounted on the side of the chassis 6, and a first track 8 is horizontally set on the side wall of the support block 7. The first track 8 is slidably connected to the translation base 9, and an electric control shaft rod 10 is set at the end of the translation base 9. A rotatable water tank 11 is fixedly mounted on the electric control shaft rod 10, and a liquid inlet valve 12 and a liquid discharge valve 15 are set on the side wall of the water tank 11. A water tank 13 is set in the middle area of ​​the chassis 6, and a first water level sensor is set in the water tank 13 for detecting the water level in the water tank 13, connecting the seawater pump to drain water in time to ensure that the water level in the water tank 13 is qualified, and an intelligent valve 14 that can be connected to an external pipeline is set at the bottom of the water tank 13. The pipeline between the water tank 13 and the liquid inlet valve 12 is connected to the first telescopic conduit 16, and the pipeline between the water tank 13 and the liquid discharge valve 15 is connected to the second telescopic conduit 17. The first telescopic conduit 16 and the second telescopic conduit 17 are both made of corrosion-resistant material. The external pipeline is manually connected to the intelligent valve 14. The valve 14 can be used to input seawater into the water tank 13, and then the seawater is transported to the first telescopic conduit 16 through the first water pump arranged in the water tank 13, and the seawater is transported to the water tank 11 through the first telescopic conduit 16, thereby completing a seawater transportation process. A second water pump is arranged in the water tank 11, and the central controller controls the second water pump to transport the seawater in the water tank 11 through the drain valve 15 to the second telescopic conduit 17, and the seawater is transported to the water tank 13 through the second telescopic conduit 17, thereby completing another seawater transportation process. A second water level sensor is arranged in the water tank 11 for detecting the water level in the water tank 11. The central controller determines the tilt angle of the main body 1 according to the data received from the GNSS receiver, and then adjusts the water amount in the water tanks 11 on both sides, thereby ensuring the balance of the main body 1. The adjustment method is that the seawater in the water tank 11 on the lower side of the main body 1 flows back to the water tank 13, and at the same time, seawater is injected into the water tank 11 on the higher side of the main body 1.

[0037] An intelligent pressure relief hole 18 is provided on one side of the water tank 11. The intelligent pressure relief hole 18 is controlled by a central controller. J is a data manually preset in the central controller, representing the maximum tilting range of the main body 1 that is acceptable for this environment. If the central controller indicates, based on the data received from the GNSS receiver, that the tilting range of the main body 1 exceeds J, the intelligent pressure relief hole 18 on the water tank 11 on the lower side of the tilted main body 1 is opened, allowing the seawater in the water tank 11 to be quickly discharged through the intelligent pressure relief hole 18. The extremely fast drainage speed can help the main body 1 quickly correct its tilt angle. This rapid tilt correction process can only be used when the tilting range of the main body 1 exceeds J to prevent a large amount of seawater from accumulating around the main body 1 and affecting the environment in which the platform mechanism is located.

[0038] The seawater pump and the external pipeline are a matching structure;

[0039] The air pressure balance component includes a central air pump compartment 19 arranged between the two groups of track components 2, and two groups of buoyancy air bags 20 are arranged at the front and rear ends of the chassis 6. An independent inflation and deflation valve 21 is arranged in each group of buoyancy air bags 20, which is connected to the central air pump compartment 19 by setting a third retractable guide tube 22. The buoyancy air bag 20 is made of a polyurethane-Kevlar composite fabric resistant to salt spray corrosion. The central controller drives the inflation and deflation valve 21 to inflate or deflate the buoyancy air bag 20 to adjust the state of the buoyancy air bag 20. The use of the buoyancy air bag 20 is divided into active use and passive use. Active use is to manually control the buoyancy air bag 20 by driving the inflation and deflation valve 21 through the central controller, and control the buoyancy. The inflation volume of the airbag 20 is used to control the buoyancy airbag 20. Passive use is to obtain data through the GNSS receiver to realize the regulation of the buoyancy airbag 20. After the main body 1 arrives at the destination and is ready to start work, the buoyancy airbag 20 is opened by the central controller so that the buoyancy airbag 20 touches the ground, improving the balance of the main body 1. If the main body 1 begins to tilt, the central controller drives the buoyancy airbag 20 on the higher tilt side to start deflating, and the buoyancy airbag 20 on the lower tilt side to start inflating. Through the coordinated operation of multiple buoyancy airbags 20, the balance of the main body 1 is controlled, the purpose is to reduce the tilt speed of the main body 1, giving manual and central controllers more reaction and processing time;

[0040] If drainage is started through the intelligent pressure relief hole 18, after drainage is completed, the central controller drives the buoyancy airbag 20 on the side of the drainage hole 18 to be pressurized and inflated once, and the pressurized inflation volume is a preset value. After the buoyancy airbag 20 is pressurized and inflated, its effective volume increases, and the intelligent pressure relief hole 18 starts to drain. The drainage volume is large, and the ground humidity increases, resulting in a further decrease in the hardness of the soil in the seaside environment. By pressurizing and inflating the buoyancy airbag 20, the main body 1 on this side is further supported, so as to ensure that the tilt amplitude of the main body 1 is within the preset range for the purpose of prevention;

[0041] A connecting hose is provided between the hydraulic balance component and the air pressure balance component. One side of the connecting hose is connected to the water tank 13, and the other side is connected to the central air pump compartment 19. After the main body 1 finishes working, the central air pump compartment 19 and the intelligent pressure relief hole 18 are opened, and air is injected into the water tank 13 through the central air pump compartment 19. The air flows into the water tank through the water tank 13 and is finally discharged from the intelligent pressure relief hole 18, thereby accelerating the drying of the water tank 13 and the water tank 11. Since seawater flows through the water tank 13 and the water tank 11, which is highly corrosive, timely drying can extend the service life of the water tank 13, the water tank 11 and the connecting structure;

[0042] The water tank 13, water tank 11 and connecting structure are all modular structures, which are convenient for later maintenance and replacement;

[0043] The drilling mechanism includes a support frame 23, a telescopic assembly 24 is installed at the bottom of the support frame 23, and a limit frame assembly 25 is installed at the bottom of the telescopic assembly 24. The central controller drives the telescopic assembly 24 to move up and down, thereby driving the limit frame assembly 25 to move up and down, thereby achieving height control of the limit frame assembly 25;

[0044] The limiting frame assembly 25 includes a first electric control rod 26 fixedly mounted on the bottom of the telescopic assembly 24, an electric control shaft ball 27 is provided at the end of the first electric control rod 26, and a limiting plate 28 is installed on the electric control shaft ball 27. The two limiting plates 28 jointly limit the bored pile. The central controller drives the first electric control rod 26 to rotate, and then drives the electric control shaft ball 27 to rotate up and down, and finally drives the limiting plate 28 to rotate up and down. This process is to drive the limiting plate 28 to find a suitable angle to be flat against the ground. Since the construction area is a seaside or offshore area, the soil is soft or has a lot of moisture, and the ground is uneven, it is necessary to first find a suitable angle for the limiting plate 28, and then drive the electric control shaft ball 27 to move horizontally to the left and right to drive the limiting plate 28 to move horizontally to the left and right, and drive the limiting plate 28 to find a suitable position to circle a suitable area. This area is used for bored piles to be drilled, and is suitable for bored piles of different specifications.

[0045] The cast-in-place pile mechanism includes a column 29 fixed to the top of the support frame 23. A second track 30 is provided on the side wall of the column 29. The second track 30 is slidably connected to the guide mechanism. The central controller drives the guide mechanism to rise and fall along the second track 30, thereby controlling the contact time and frequency between the guide mechanism and the cast-in-place pile.

[0046] The guide mechanism adopts a segmented quick-release structure, including a sliding arm 49 slidably connected to the second rail 30, the sliding arm 49 is fixedly connected to the support plate 32, an electric control box assembly 33 is arranged on one side of the support plate 32, a connecting rod 34 is extended from the top of the electric control box assembly 33, a hydraulic press 35 is fixedly installed on the top of the connecting rod 34, the output end of the hydraulic press 35 is vertically downward and fixedly installed with a fixed rod 36, a third rail 37 is arranged on the side wall of the fixed rod 36, a plurality of pressure filling discs 31 are slidably connected to the third rail 37, and a protective assembly is fixedly installed at the bottom of the fixed rod 36, the sliding arm 49 is driven by the central controller to rise and fall along the second rail 30, and then the support plate 32 is driven to rise and fall, and then the electric control box assembly 33 is driven to rise and fall, and then the connecting rod 34 is driven to rise and fall, in order to drive the hydraulic press 35 to perform a long-distance initial motion process, and wait for the central controller to drive the hydraulic press 35 to enter a preset position, which is the movement distance of the hydraulic press 35 from the bored pile. The optimal position, further, the hydraulic press 35 runs to drive the fixed rod 36 to press and move downward, driving the protective assembly to press and move downward, and the protective assembly is used to push the bored pile into the ground, and then the pressure plate 31 is driven to press down along the third track 37 to apply pressure to the protective assembly and then to the bored pile column, and the central controller drives the multiple groups of pressure plates 31 to press down in sequence from bottom to top, and there is an interval between the pressing processes of each group of pressure plates 31. By dividing the single processing of the bored pile column by the entire bored pile mechanism into several groups of pressure plates 31, the bored pile column is processed multiple times, the purpose is to reduce the single pressure on the bored pile column and thus reduce the vibration amplitude of the bored pile column during the processing. The bored pile is processed in the seaside or offshore area with soft soil. The high-intensity hammering action will cause the path of the bored pile entering the ground to deviate. After all the pressure plates 31 are pressed down, the central controller drives all the multiple groups of pressure plates 31 to reset and repeat the pressing process.

[0047] Multiple groups of pressure filling plates 31 are connected by tapered pins 38, and the surface of the tapered pins 38 is coated with a hard alloy layer to prevent wear;

After the first support plate 41 is against the top surface of the cast-in-place pile, the central controller drives the second support plate 43 to move down along the fourth track 42 to fit the universal shaft ball 40, fixing the universal shaft ball 40, so that the first support plate 41 is locked and then continuously fits with the cast-in-place pile;

[0049] A groove 44 matching the shape of the top of the universal joint ball 40 is provided at the bottom of the second support plate 43 to limit the movement of the universal joint ball 40;

Before processing the bored pile column, the central controller drives the second electric control rods 45 on both sides to rotate and drive the counterweight plate 46 to a position parallel to the ground, and then drives the third electric control rod 47 to rotate and drive the measuring plate 48 to a position perpendicular to the ground. When processing the bored pile, the third electric control rod 47 is in a passive state, that is, the measuring plate 48 swings according to the state of the bored pile mechanism, so that the tilt amplitude of the bored pile mechanism can be directly observed manually.
