[0061] The present invention will be described in detail below with reference to specific embodiments. These embodiments are merely some, not all, implementations of the present invention. All other implementations obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0062] Example 1

[0063] The implementation steps of a sustainable pressurized rotary drilling and vibratory compaction construction process are as follows:

[0064] 1. Before vibratory compaction, ensure all construction equipment is on site and optimally tested. Also, check that all necessary materials are complete and meet quality requirements. Clean the construction site to ensure there are no obstructions, providing a safe and clean environment for construction. Furthermore, conduct technical briefings and safety training for construction personnel to ensure that each worker understands the construction process and precautions.

[0065] 2. Based on the design drawings and project requirements, use surveying instruments to accurately measure the construction area and determine the precise locations of the piles. During the measurement process, care must be taken to avoid errors and ensure the accuracy of the pile positions. Simultaneously, the pile positions should be arranged according to the design requirements, with reasonable planning of pile spacing and row spacing to ensure the overall construction effect.

[0066] 3. Move the rotary drilling and vibratory compaction equipment to the construction area. The equipment includes a vibratory compactor and a power head to drive its rotation. Then, move the vibratory compactor to the designated pile position and perform precise positioning. After positioning, check the verticality and stability of the vibratory compactor to ensure it is in normal working condition. During the positioning process, care should be taken to avoid damaging the surrounding environment and to ensure the safety of construction personnel.

[0067] 4. Slowly and steadily lift the vibratory compactor, align it with the pile position, and slowly lower it until it is within 30cm of the ground. Then, start the water pump and adjust the water outlet to 100m. 3 / h; Start the vibratory compactor and rely on the horizontal vibration force of the vibratory compactor to expand the soil and rock.

[0068] Step 5: The power head drives the vibratory compactor to rotate, and holes are created through drilling, horizontal vibration expansion, and high-pressure water impact.

[0069] 6. The vibratory compactor's head can be equipped with cutting tools (or roller cones) at its front end. Roller cones provide stable crushing force in formations of varying hardness, achieving compaction of soil and rock layers; cutting tools directly contact the formation, cutting through hard obstacles such as gravel and rocks to assist the vibratory compactor in hole formation. During hole drilling, the vibratory compactor should always be kept suspended to ensure vertical hole formation. As the guide rod lengthens and the hole deepens, the vibratory compactor descends accordingly. Drilling stops once the designed depth is reached.

[0070] 7. During hole drilling, a hole cleaning operation will be performed. Water from the waterway will be used to carry away the thick mud from the hole until the mud returning from the hole opening becomes thinner. During hole cleaning, mud lumps and debris near the hole opening should be removed to prevent them from falling into the hole and causing blockage.

[0071] 8. According to design requirements, fill the pile hole in sections with reinforcing materials such as crushed stone (pebbles). When adding reinforcing materials, pay attention to controlling the amount and ratio of materials to ensure that they are mixed evenly with the soil. At the same time, avoid clogging the vibratory compactor or causing environmental pollution.

[0072] 9. Using the horizontal excitation force of the vibratory compactor, the reinforcing material filled into the borehole is continuously squeezed into the sidewall soil layer, simultaneously compacting the fill material until the design requirements are met. Compaction begins at the bottom of the borehole and proceeds upwards segment by segment, with the vibratory compactor raised 50cm each time, ensuring proper overlap and compaction of each segment to prevent missed vibration. The solid fill material is compacted segment by segment until the borehole opening, forming a composite foundation.

[0073] Example 2

[0074] like Figure 1-6 The rotary drilling and vibratory compaction equipment also includes a body 1. One end of the body 1 is equipped with an amplitude-changing mechanism 2. The amplitude-changing mechanism 2 is connected to a mast 3 through its movable end. The amplitude-changing mechanism 2 can adjust the angle of the mast 3 to ensure that the mast 3 is perpendicular to the ground, thereby ensuring the quality of pile formation. A power head 5 and an auxiliary positioning component 7 are slidably connected to the side of the mast 3 away from the body 1. The power head 5 is used to drive the drilling mechanism 6 to work, and the auxiliary positioning component 7 provides precise guidance for the movement of the drilling mechanism 6. The drilling mechanism 6, which is rotatably connected to the power head 5, forms an integral structure. The drilling mechanism 6 can rotate under the drive of the power head 5, thereby realizing the cutting operation of rock and soil.

[0075] The drilling mechanism 6 includes a guide rod 61 located between the power head 5 and the auxiliary positioning component 7. The guide rod 61 is a key transmission component for drilling. The bottom end of the guide rod 61 is connected to a vibratory compactor 63. During operation, the vibratory compactor 63 can generate a horizontal excitation force to squeeze and expand the softer soil and rock to both sides to improve drilling efficiency. The top end of the guide rod 61 is provided with a lifting head 62. The lifting head 62 cooperates with the guide wheel system of the mast 3 through a steel rope to realize the vertical displacement of the guide rod 61, thereby controlling the drilling depth.

[0076] The power head 5 is slidably connected to the positioning frame 51 on the outside of the mast 3. The positioning frame 51 is used to guide the power head 5 to move along the mast 3 to complete the drilling operation. The outer side of the positioning frame 51 is connected to the base 52. The driven gear 55 is rotatably connected to the inside of the base 52 through the bearing. The driven gear 55 is used to transmit power to drive the guide rod 61 to rotate. The top of the driven gear 55 is connected to the spline inner sleeve 54. The spline inner sleeve 54 cooperates with the spline structure of the guide rod 61 to achieve efficient power transmission. The outer side of the positioning frame 51 is also equipped with a motor 53. The motor 53 is the power source of the entire drive system. By driving the driven gear 55 to rotate, it drives the spline inner sleeve 54 and the guide rod 61 to rotate synchronously.

[0077] The outer side of the vibratory compactor 63 is provided with cutting teeth 631 evenly distributed around its axis. The cutting teeth 631 are the key cutting components of the vibratory compactor 63. During drilling operations, the cutting teeth 631 cut the rock and soil through rotational motion. Combined with the horizontal excitation force generated by the vibratory compactor 63, the rock and soil can be quickly crushed and removed, thereby improving drilling efficiency.

[0078] A cylinder 4 is connected to the side of the mast 3, and the telescopic end of the cylinder 4 is connected to the power head 5. The cylinder 4 can adjust the height and position of the power head 5 through telescopic movement, ensuring that the connection between the power head 5 and the drilling mechanism 6 is accurate, thereby further improving the stability and efficiency of drilling.

[0079] The mast 3 is provided with a first guide wheel 31 and a second guide wheel 32 on its side and top, respectively. The first guide wheel 31 and the second guide wheel 32 provide a guiding path for the steel rope, ensuring that the steel rope can smoothly transmit the tension. The top of the lifting head 62 is connected to a steel rope, which passes around the second guide wheel 32 and the first guide wheel 31 in sequence. The lifting head 62 and the guide rod 61 are raised and lowered by the action of the guide wheel system, thereby accurately controlling the drilling depth.

[0080] The guide rod 61 includes an inner tube 611 and an outer tube 612, which are sliding fit structures. The inner tube 611 and the outer tube 612 can slide to adjust the extension and retraction of the guide rod 61, thereby controlling the accuracy of the drilling depth and adapting to the construction needs of different geological conditions.

[0081] The guide rod 61 cooperates with the spline inner sleeve 54. The rotational motion of the spline inner sleeve 54 is efficiently transmitted to the guide rod 61 through the spline transmission structure. When the spline inner sleeve 54 rotates, the guide rod 61 can rotate synchronously, thereby driving the vibratory punch 63 and the cutting tooth 631 to perform cutting operations.

[0082] The positioning frame 51 has symmetrically arranged locking claws 511 on its side, which are slidably connected to the mast 3. The design of the locking claws 511 can provide additional positioning support during the sliding of the power head 5, preventing the power head 5 from shifting on the mast 3, thereby further improving the accuracy and stability of the drilling operation.

[0083] The guide rod 61 has a multi-section structure, and its length can be flexibly adjusted according to construction needs to adapt to construction requirements at different depths. During the drilling process, the locking point design between the power head 5 and the guide rod 61 allows the equipment to lock and unlock flexibly; the downward pressure of the power head 5 is transmitted to the vibratory compactor 63 and the cutting teeth 631 through the guide rod 61, ensuring efficient crushing of the soil and rock layers. The vibratory compactor 63 is driven by a hydraulic system. In soft strata, it diffuses the soil and rock through horizontal vibration force. In hard strata, it works with the cutting teeth 631 to cut and expand the crushed soil and rock, ultimately forming a hole.

[0084] In some embodiments, in step 5, the power head drives the guide rod 61 to rotate clockwise, and moves the power head up and down via a hydraulic cylinder or winch to bring the male key into the female keyway, thereby transmitting torque and enabling the pressurized drill bit to penetrate the formation. By matching guide rods 61 of different lengths or numbers, construction needs at different depths can be met.

[0085] In some embodiments, in step 9, the guide rod 61 is first driven to rotate counterclockwise by the power head, thereby unlocking the locking points of the upper and lower sections of the guide rod 61. Then, relying on the horizontal excitation force of the vibratory compactor, the reinforcing material filled in the hole is continuously squeezed into the sidewall soil layer.

[0086] When in use, the machine body 1 moves to the predetermined drilling position, and the angle of the mast 3 is adjusted by the luffing mechanism 2 to make the mast 3 perpendicular to the ground to be drilled, so as to ensure the quality of pile formation. At the same time, the luffing mechanism 2 can realize the switching between working state and transportation state of the pile driver.

[0087] Then, under the action of the vibratory compactor 63, a horizontal excitation force is generated, which can squeeze and expand the rock and soil to both sides for softer strata;

[0088] During the drilling process, the power head 5 drives the guide rod 61 to rotate, and the guide rod 61 drives the vibratory compactor 63 to rotate. During the rotation process, torque is transmitted simultaneously. Finally, the cutting teeth 631 set on the front end of the vibratory compactor 63 cut the rock and soil, thereby improving the drilling efficiency.

[0089] When the power head 5 is running, the positioning frame 51 drives the driven gear 55 inside the base 52 to rotate. During the rotation of the driven gear 55, it will drive the spline inner sleeve 54 connected to the top of the driven gear 55 to rotate synchronously. The spline inner sleeve 54 and the guide rod 61 are engaged with each other. When the spline inner sleeve 54 rotates, it will drive the guide rod 61 to rotate synchronously.

[0090] During drilling, the drilling depth can be controlled by adjusting the extension and retraction of the inner tube 611 and the outer tube 612.

[0091] Example 3

[0092] like Figure 7-10 The drilling mechanism 6 is coaxially connected to a water / oil pipeline anti-rotation lifting device 10. The water / oil pipeline anti-rotation lifting device 10 includes a traction head 11. The traction head 11 has a channel 11 for passing through oil and water pipes. The channel 11 extends through the upper part of the traction head 11 and has sufficient space to accommodate oil and water pipes of different diameters. A connector 12 for connecting a steel rope is provided at the top of the traction head 11. The connector 12, through its compact design, ensures a stable connection of the steel rope. An outer sleeve 12 is securely connected to the bottom end of the traction head 11. The inner side of the outer sleeve 12 is connected to a precision-machined bearing. The inner component 13 is dynamically connected, enabling efficient relative rotation with the outer component 12. Evenly distributed rollers 14 are provided between the outer component 12 and the inner component 13, further enhancing rotational smoothness and durability by reducing friction. A guide rod connector 15 is tightly connected to the bottom of the inner component 13. A hydraulic return ring 17 is provided on the inner side of the guide rod connector 15, enabling oil input and output through its built-in hydraulic channel. A guide rod 61 is installed on the outer side of the guide rod connector 15, and its length can be adjusted to adapt to different construction scenarios.

[0093] The bottom of the outer kit 12 is provided with a first stop 121, which restricts the axial displacement of the roller 14 through a reliable fixing method; the top outer side of the inner kit 13 is provided with a second stop 131, and the position design of the second stop 131 ensures that the roller 14 is always kept within the limited range; the roller 14 is located between the first stop 121 and the second stop 131, and the roller 14 forms a stable support structure between the first stop 121 and the second stop 131 through the uniform force distribution, avoiding the roller 14 from shifting or failing due to external load, thereby ensuring the long-term reliable operation of the inner kit 13 and the outer kit 12.

[0094] The inner bottom of the traction head 11 is connected to a fixing frame 16 by bolts or welding. The fixing frame 16 enhances stability. The fixing frame 16 is tightly connected to the outer upper end of the hydraulic loop 17. The design of the hydraulic loop 17 allows it to rotate synchronously with the vibratory impactor when the pipeline is connected. The lower end of the hydraulic loop 17 is firmly fixed to the innermost top of the guide rod 61. The layered structure of the guide rod 61 can be freely extended and adjusted according to the actual working conditions of the vibratory impactor to ensure that the connection between the water pipe and the oil pipe is stable and will not be affected by additional torsional force.

[0095] A flange ring 114 is fixedly connected to the outer side of the bottom end of the traction head 11. The flange ring 114 is tightly connected to other devices through precisely machined screw holes. The structural design of the flange ring 114 not only provides additional fixing support, but also ensures the sealing between the traction head 11 and the lower structure, thereby improving the overall seismic resistance and durability of the device.

[0096] The side of the connector 12 is provided with a through groove 1121 and a through hole 1122, which are distributed in an alternating manner. The through groove 1121 facilitates the quick placement of the steel rope buckle end into it, and a pin 113 is inserted into the through hole 1122. The pin 113 is designed with precisely matched size and material to ensure that the steel rope will not fall off or slip during the connection process, thereby improving the connection stability and reliability between the traction head 11 and the steel rope.

[0097] In use, place the buckle end of the traction steel rope into the through groove 1121, and let the pin 113 pass through the connecting buckle of the steel rope, thereby connecting the steel rope to the connector 12.

[0098] The oil pipe and water pipe are inserted into the channel 11. One end of the oil pipe is connected to the input end at the top of the hydraulic loop 17, and the oil pipe is connected between the output end at the bottom of the hydraulic loop 17 and the vibratory impactor.

[0099] During the piling process using a vibratory compactor, when the vibratory compactor rotates, the inner sleeve 13 and the outer sleeve 12 will rotate synchronously, and the hydraulic loop 17 connected to the vibratory compactor will remain relatively stationary, thereby preventing the oil pipe from twisting during the piling process.

[0100] Furthermore, it should be understood that those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
