Description

Technical Field

[0001] This invention relates to the field of foundation treatment technology, and more specifically, to a pre-drilling and vibratory compaction integrated device. Furthermore, it also relates to a construction method including the aforementioned pre-drilling and vibratory compaction integrated device. Background Technology

[0002] Vibro-compaction is a method of foundation treatment. It generally involves using a crane or drilling rig to lift a vibro-compactor with a guide rod. Under the excitation force generated by the vibro-compactor, the loose foundation soil layer is compacted. Alternatively, after vibro-compacting holes in the foundation soil layer, crushed stone or other materials are filled into the holes, and the crushed stone is vibrated and compacted section by section to form vibro-compacted crushed stone piles. These piles, together with the surrounding foundation soil, form a composite foundation, thereby achieving the purpose of improving the foundation bearing capacity, increasing foundation stability, and enhancing the foundation's resistance to earthquake liquefaction.

[0003] In recent years, with the development of urban infrastructure, the application of vibro-compaction has become increasingly widespread. However, this has also brought new difficulties and challenges to construction, mainly manifested in the difficulty of drilling through complex geological formations and poor quality control. For some complex geological conditions, the current conventional approach is to first drill holes using a long auger or rotary drilling rig, and then use a vibro-compaction device. However, due to the coordinated operation of multiple devices, frequent equipment movement is required, which can easily lead to borehole collapse. Therefore, mud slurry is used for wall protection, causing environmental pollution. While the above approach can significantly improve construction efficiency, the use of multiple devices results in high costs and some pollution.

[0004] In summary, how to integrate the hole-reaming device and the vibratory punching device is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide an integrated drilling and vibratory punching device that can realize the integration of the drilling device and the vibratory punching device.

[0006] Another object of the present invention is to provide a construction method including the above-mentioned integrated drilling and vibratory compaction equipment.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A pre-hole vibratory punching integrated device, comprising:

[0009] A drilling device includes a power head, a spiral drill rod connected to the power head and used for drilling, and an openable drilling retainer;

[0010] A vibratory compaction device includes a guide rod, a vibratory compactor disposed at the bottom of the guide rod for vibrating and compacting soil, an openable upper retainer, and an openable lower retainer;

[0011] The pile frame has vertically distributed columns, on which are vertically spaced first and second guide rails. The fixing parts of the upper and lower retainers are both used to slide along the first guide rail. The opening and closing parts of the upper and lower retainers are sleeved on the outer periphery of the guide rod to selectively lock or pass through the guide rod. The fixing parts of the power head and the pilot hole retainer are both used to slide along the second guide rail. The opening and closing part of the pilot hole retainer is sleeved on the outer periphery of the auger drill rod to limit the position of the auger drill rod.

[0012] The pile frame is equipped with multiple winches, and the top of the column is equipped with a goose head. The wire rope of one winch falls through the goose head to connect with the upper retainer, and the wire rope of the other winch falls through the goose head to connect with the power head.

[0013] In one embodiment, the lower retainer includes a lower retaining movable member, a lower retaining fixed member, and a lower connecting pin for connecting the lower retaining movable member and the lower retaining fixed member, wherein the lower retaining fixed member is provided with a lower gripper for sliding along the first guide rail;

[0014] The lower retaining movable member and the lower retaining fixed member are provided with a lower through hole for passing through the guide rod. The inner wall of the lower through hole is provided with at least two lower key strips in the circumferential direction. A lower pin mechanism is provided between two adjacent lower key strips. The guide rod is provided with a lower key groove that engages with the lower key strips. The lower pin mechanism moves radially along the lower through hole to selectively engage or pass through the guide rod.

[0015] In one embodiment, the lower pin mechanism is connected to the lower safety device to prevent accidental contact with the lower pin mechanism from causing the guide rod to fall.

[0016] In one embodiment, the lower retaining pin mechanism includes a lower retaining cylinder and a lower retaining pin connected to the lower retaining cylinder, the lower retaining pin being arranged radially along the lower through hole;

[0017] The lower safety device includes a lower retaining limit shaft, a lower sleeve sleeved on the outer periphery of the lower retaining limit shaft, and a lower retaining return spring embedded in the lower sleeve. One end of the lower retaining limit shaft is vertically inserted into the lower retaining pin, and the other end of the lower retaining limit shaft is used to connect to a rope so that the operator can pull and control it by hand. The lower retaining return spring is used to drive the lower retaining limit shaft to return to its original position.

[0018] In one embodiment, the upper retainer includes an upper retaining movable member, an upper retaining fixed member, and an upper connecting pin for connecting the upper retaining movable member and the upper retaining fixed member. The upper retaining fixed member has an upper gripper on one side for sliding along the first guide rail, and an upper pulley assembly is provided on the top of the upper retaining fixed member for winding the wire rope.

[0019] The upper retaining movable member and the upper retaining fixed member are provided with an upper through hole for passing through the guide rod. The inner wall of the upper through hole is provided with at least two upper key strips along the circumferential direction. An upper pin mechanism is provided between two adjacent upper key strips. The guide rod is provided with an upper keyway for engaging with the upper key strips. The upper pin mechanism is used to move radially along the upper through hole to selectively engage or pass through the guide rod.

[0020] In one embodiment, the bottom of the upper retainer is provided with two oppositely distributed, semi-circular retaining plates, which are engaged in the slots of the guide rod for suspension positioning during the overall installation of the guide rod.

[0021] In one embodiment, the upper pin mechanism is connected to the upper safety device to prevent accidental activation of the upper pin mechanism from causing the guide rod to fall.

[0022] In one embodiment, the upper retaining pin mechanism includes an upper retaining cylinder and an upper retaining pin connected to the upper retaining cylinder, the upper retaining pin being arranged radially along the upper through hole;

[0023] The upper safety device includes an upper retaining limit shaft, an upper sleeve sleeved on the outer periphery of the upper retaining limit shaft, and an upper retaining return spring embedded in the upper sleeve. One end of the upper retaining limit shaft is vertically inserted into the upper retaining pin, and the other end of the upper retaining limit shaft is used to connect to a rope so that the operator can pull and control it by hand. The upper retaining return spring is used to drive the upper retaining limit shaft to return to its original position.

[0024] In one embodiment, the guide rod includes multiple detachably connected pipe sections, with a top plate at the top of the topmost pipe section. Cables and water / gas pipes are housed inside the guide rod, and the top plate is equipped with a pipe guide to constrain the length of the cables and water / gas pipes inside the guide rod.

[0025] A construction method comprising the pre-drilling and vibratory compaction equipment described in any of the above claims.

[0026] When using the integrated drilling and vibratory compaction equipment provided by this invention, firstly, the upper retainer can be opened (i.e., the hinge between the opening / closing part and the fixed part of the upper retainer is opened), and its opening / closing part is installed at the corresponding position of the guide rod. The bottom clamping plate (i.e., the clamping plate) of the upper retainer is then clamped at the corresponding position of the guide rod. Then, the wire rope wound on the pile frame is connected to the upper retainer via the pulley block extending from the gooseneck, and the fixed parts of the upper and lower retainers are slidably mounted on the first guide rail on the side of the column. The opening / closing parts of the upper and lower retainers are controlled to retract so that the guide rod passes through the upper and lower retainers. Afterwards, the guide rod can be lifted to below the upper retainer using relevant auxiliary equipment, and the hinge between the fixed part and the opening / closing part of the upper retainer is connected using a pin.

[0027] Then, using a winch to lift the upper retainer, the guide rod continues to be suspended by related auxiliary equipment to prevent it from touching the bottom and damaging the water and air pipes and cables. Once the guide rod is nearly vertical, another winch lifts the lower retainer, allowing the guide rod to pass through it. The opening and closing part of the lower retainer is extended to lock the guide rod in place, and a pin connects the hinge between the fixed part and the opening and closing part of the lower retainer. Next, the vibratory shock absorber and buffer device are installed. First, the buffer device is installed at the bottom of the guide rod, then the vibratory shock absorber is installed directly below the buffer device, and the vibratory shock absorber's cable and water and air pipes are connected.

[0028] Subsequently, the lower retainer retracts to pass the guide rod, and the upper retainer clamps the guide rod and falls under gravity. When the upper retainer approaches the lower retainer, the lower retainer extends to lock the guide rod. Alternatively, the bottom clamping plate of the upper retainer can be removed, and the upper retainer retracts to pass the guide rod. At this point, the upper and lower retainers are close, and the upper retainer can move relative to the guide rod. Under the pulling action of the winch wire rope, the upper retainer moves upward along the guide rod. When the upper retainer reaches the top of the guide rod, the upper retainer extends to lock the guide rod, and the lower retainer and guide rod are separated (i.e., the lower retainer retracts to pass the guide rod). The wire rope pulls the upper retainer and guide rod up and down, preventing the guide rod from protruding too much above the upper retainer, allowing the guide rod that extends above the machine to be inserted into the hole, ensuring the vibrating hole reaches the required depth.

[0029] Finally, the pulley block extending from the winch of the power head can be installed as a whole onto the second guide rail of the column. Then, the auger rod is connected to the power head, and the fixing part of the pilot hole retainer is installed on the second guide rail of the column. The opening and closing part of the pilot hole retainer is sleeved on the outer periphery of the auger rod to limit the position of the auger rod and prevent large deviations from occurring when the auger rod is drilling.

[0030] After the equipment is assembled, different geological development operations can be carried out according to different geological development reports. For example, the vibratory compaction device can be used directly for vibratory drilling, or the pilot hole device can be used first for pilot hole drilling, and then the vibratory compaction device can be used for vibratory drilling. During use, the upper retainer (which holds the guide rod in place) or the power head can be lifted simply by using a winch, thereby lifting the guide rod or auger drill rod. This equipment is equipped with double guide rails on the column, allowing the pilot hole device and the vibratory compaction device to run along different guide rails, integrating pilot hole drilling and vibratory compaction methods into one. This achieves the goal of pilot hole drilling for a single pile, preventing the entire vibratory compaction machine from shifting, avoiding hole collapse, and making the vibratory drilling and pilot hole drilling operations highly efficient and easy to replace.

[0031] In summary, the integrated drilling and vibratory punching device provided by this invention can realize the integration of the drilling device and the vibratory punching device.

[0032] In addition, the present invention also provides a construction method including the above-mentioned integrated drilling and vibratory compaction equipment. Attached Figure Description

Detailed Implementation

[0061] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0062] The core of this invention is to provide an integrated drilling and vibratory compaction device, which integrates the drilling device and the vibratory compaction device into one unit. Another core aspect of this invention is to provide a construction method including the aforementioned integrated drilling and vibratory compaction device.

[0063] Please refer to Figures 1 to 25 .

[0064] This specific embodiment provides an integrated drilling and vibratory punching device, including:

[0065] The drilling device 24 includes a power head 2, a spiral drill rod 23 connected to the power head 2 and used for drilling, and an openable drilling retainer 19.

[0066] The vibratory compaction device 25 includes a guide rod 22, a vibratory compactor 20 disposed at the bottom of the guide rod 22 for vibrating and compacting the soil, an openable upper retainer 4, and an openable lower retainer 21.

[0067] The pile frame 26 has vertically distributed columns 3, and vertically spaced first guide rails 3.1 and second guide rails 3.2 are provided on the columns 3. The fixing parts of the upper retainer 4 and the lower retainer 21 are used to slide along the first guide rail 3.1. The opening and closing parts of the upper retainer 4 and the lower retainer 21 are sleeved on the outer periphery of the guide rod 22 to selectively lock or pass through the guide rod 22. The fixing parts of the power head 2 and the pilot hole retainer 19 are used to slide along the second guide rail 3.2. The opening and closing part of the pilot hole retainer 19 is sleeved on the outer periphery of the auger drill rod 23 to limit the position of the auger drill rod 23.

[0068] The pile frame 26 is equipped with multiple winches, and the top of the column 3 is equipped with a goose head 1. The wire rope of one winch falls through the goose head 1 to connect with the upper retainer 4, and the wire rope of the other winch falls through the goose head 1 to connect with the power head 2.

[0069] It should be noted that, as Figure 5 As shown, the first guide rail 3.1 and the second guide rail 3.2 on the column 3 are spaced apart. This can mean that the first guide rail 3.1 and the second guide rail 3.2 are relatively distributed or at a certain angle, facilitating the assembly of different working devices so that the pre-drilling device 24 and the vibratory compaction device 25 can work together. Furthermore, a ladder 3.3 can be installed on the column 3 to allow workers to inspect or operate the device. In addition, the vibratory compaction device 25 must be installed before the pre-drilling device 24 during use. This is because the guide rod 22 is relatively long and needs to be changed from a horizontal to a vertical position, requiring a large space. If the vibratory compaction device 25 and the pre-drilling device 24 are installed simultaneously, it will occupy the space required for the vibratory compaction device 25, making it difficult to install smoothly. After the vibratory compaction device 25 and the pre-drilling device 24 are installed, either the vibratory compaction device 25 or the pre-drilling device 24 can be selected for operation as needed. This device integrates pre-drilling and vibratory compaction operations, featuring good pile quality, controllable vertical accuracy, high construction efficiency, and good overall safety and stability.

[0070] Additionally, it should be noted that the top of the column 3 is equipped with a goose head 1, which has a lot of pulleys to change the direction of rotation. Both the power head 2 and the upper retainer 4 can move up and down relative to the guide rail of the column 3. The upper retainer 4 and the lower retainer 21 not only guide the guide rod 22, but also prevent the guide rod 22 from rotating. The pilot hole retainer 19 mainly guides the auger drill rod 23 and does not restrict the rotation of the auger drill rod 23.

[0071] It should also be noted that the pile frame 26 is equipped with a diagonal bracing assembly 5 (located on opposite sides of the columns 3 to ensure the columns 3 are vertically distributed), a mast mechanism 6 (used to connect the diagonal bracing assembly 5 and the columns 3), a hydraulic pump station 7 (this device is fully hydraulically driven, the hydraulic pump station 7 is driven by a motor, and the motor is connected to an external power source), a hydraulic oil tank 8 (i.e., all hydraulic oil in the device is supplied by the hydraulic oil tank 8), an auxiliary winch 9 (which is the smallest winch, serving as a backup for subsequent lifting of some small parts), a driver's cab 10 (i.e., all automatic control operations of this device are completed in the driver's cab 10, which is equipped with a display screen and control levers, etc.), and a short boat assembly 11 ( It is used to realize the forward and backward movement of the device), 1# main winch 12 (one for use and one for backup), 2# main winch 13 (for example, it can be connected to the power head 2 to realize the lifting operation of the power head 2), 3# main winch 14 (for example, it can be connected to the upper retainer 4 to realize the lifting operation of the upper retainer 4), counterweight assembly 16 (used to lower the center of gravity of the whole machine and improve the safety of the whole vehicle), long boat assembly 17 (used to realize the left and right movement of the device), lifting mechanism 18 (for example, it includes multiple vertical hydraulic cylinders, the hydraulic cylinders are fixed on the upper part of the machine body, and the lifting end of the hydraulic cylinders is connected to the bottom of the long boat assembly 17 and the short boat assembly 11 respectively, so as to realize the spatial movement operation of the whole machine).

[0072] In one embodiment, such as Figures 6 to 9 As shown, the lower retainer 21 includes a lower retaining movable member 21.1, a lower retaining fixed member 21.4, and a lower connecting pin 21.7 for connecting the lower retaining movable member 21.1 and the lower retaining fixed member 21.4. The lower retaining fixed member 21.4 is provided with a lower gripper 21.5 for sliding along the first guide rail 3.1.

[0073] The lower retaining movable member 21.1 and the lower retaining fixed member 21.4 are fitted together with a lower through hole for the guide rod 22 to pass through. The inner wall of the lower through hole is provided with at least two lower key strips 21.3 (e.g.) circumferentially. Figure 8 As shown, three lower key bars 21.3 are evenly spaced along the circumference. A lower pin mechanism 21.2 is provided between two adjacent lower key bars 21.3. The guide rod 22 is provided with a lower keyway that engages with the lower key bar 21.3. The lower pin mechanism 21.2 moves radially along the lower through hole to selectively engage or pass through the guide rod 22.

[0074] It should be noted that the lower retainer 21 adopts an openable design to facilitate the installation of the guide rod 22. The inner wall of the lower through hole is provided with three protruding lower key strips 21.3. The lower key strips 21.3 are used to prevent the vibrator 20 and the guide rod 22 from rotating. Moreover, a lower pin mechanism 21.2 is provided between two adjacent lower key strips 21.3. This refers to the position of the lower pin mechanism 21.2 in the top view (i.e., the circumferential position of the lower pin mechanism 21.2). In fact, the lower pin mechanism 21.2 is installed on the top of the lower retainer 21 (i.e., the axial position of the lower pin mechanism 21.2). For example, it can be controlled by a hydraulic cylinder to drive the pin of the lower pin mechanism 21.2 to extend and retract laterally, thereby locking the guide rod 22 for fixation, or separating it from the guide rod 22.

[0075] In one embodiment, the lower pin mechanism 21.2 and the lower safety device 21.6 are connected to prevent the guide rod 22 from falling due to accidental contact with the lower pin mechanism 21.2. This prevents the guide rod 22 from falling off and causing a dangerous accident if the lower pin mechanism 21.2 is not in place during operation.

[0076] In one embodiment, such as Figure 9 As shown, the lower pin mechanism 21.2 includes a lower retaining cylinder 21.2.1 and a lower retaining pin 21.2.2 connected to the lower retaining cylinder 21.2.1. The lower retaining pin 21.2.2 is arranged radially along the lower through hole. The lower safety device 21.6 includes a lower retaining limiting shaft 21.2.3, a lower sleeve sleeved on the outer periphery of the lower retaining limiting shaft 21.2.3, and a lower retaining return spring 21.2.4 embedded in the lower sleeve. One end of the lower retaining limiting shaft 21.2.3 is vertically inserted into the lower retaining pin 21.2.2, and the other end of the lower retaining limiting shaft 21.2.3 is used to connect to a rope for manual control by the operator. The lower retaining return spring 21.2.4 is used to drive the lower retaining limiting shaft 21.2.3 to return to its original position.

[0077] It should be noted that one or more of the three sets of lower pin mechanisms 21.2 are equipped with a lower safety device 21.6. Before the lower retaining pin 21.2.2 retracts, the lower retaining limit shaft 21.2.3 must be pulled down and the lower retaining pin 21.2.2 must be pulled out (the lower retaining return spring 21.2.4 can automatically reset) before the lower retaining cylinder 21.2.1 can be activated. This is to prevent the guide rod 22 from falling off if the lower pin mechanism 21.2 is not in place during operation.

[0078] In one embodiment, the upper retainer 4 includes an upper retaining movable member 4.1, an upper retaining fixed member 4.10, and an upper connecting pin 4.5 for connecting the upper retaining movable member 4.1 and the upper retaining fixed member 4.10. The upper retaining fixed member 4.10 has an upper gripper 4.7 on one side for sliding along the first guide rail 3.1. The upper retaining fixed member 4.10 has an upper pulley assembly 4.4 on its top. The upper pulley assembly 4.4 is used to wind a wire rope. Therefore, by controlling the operation of the winch, the upper pulley assembly 4.4 and the upper retainer 4 can be driven to move up and down.

[0079] The upper retaining movable part 4.1 and the upper retaining fixed part 4.10 are provided with an upper through hole for the guide rod 22 to pass through. The inner wall of the upper through hole is provided with at least two upper key strips 4.3 in the circumferential direction (for example, three upper key strips 4.3 are provided at equal intervals in the circumferential direction along the inner wall of the upper through hole). An upper pin mechanism 4.2 is provided between two adjacent upper key strips 4.3. The guide rod 22 is provided with an upper keyway for engaging with the upper key strips 4.3. The upper pin mechanism 4.2 is used to move radially along the upper through hole to selectively engage or pass through the guide rod 22.

[0080] It should be noted that the upper retainer 4 adopts an openable design to facilitate the installation of the guide rod 22. The inner wall of the lower through hole has three raised upper key strips 4.3, which are used to prevent the vibrator 20 and the guide rod 22 from rotating. Furthermore, an upper pin mechanism 4.2 is provided between two adjacent upper key strips 4.3. This refers to the position of the upper pin mechanism 4.2 from a top-down view (i.e., indicating the circumferential position of the upper pin mechanism 4.2). In reality, the upper pin mechanism 4.2 is installed on the top of the upper retainer 4 (i.e., indicating the axial position of the upper pin mechanism 4.2). For example, it can be controlled by a hydraulic cylinder to drive the pin of the upper pin mechanism 4.2 to extend and retract laterally, thereby locking the guide rod 22 for fixation, or separating it from the guide rod 22. Further, the slot on the guide rod 22 for engaging with the upper retainer 4 can be set as an inverted U-shaped groove, such as... Figure 16 As shown, this is so that the upper retainer 4 can be engaged and fixed as it moves along the guide rod 22, preventing the upper retainer 4 from detaching from the top of the guide rod 22.

[0081] In one embodiment, such as Figure 18 As shown, the bottom of the upper retainer 4 has two opposing, semi-circular retaining plates 4.9. The retaining plates 4.9 are engaged in the slots of the guide rod 22 for suspension positioning during the overall installation of the guide rod 22. For example, the retaining plates 4.9 can be installed at the bottom of the upper retainer 4 using fasteners 4.8. Furthermore, protrusions can be provided on the retaining plates 4.9, and slots can be provided at corresponding positions on the guide rod 22 to achieve the snap-fit ​​fixation between the retaining plates 4.9 and the guide rod 22 for suspension positioning during the overall installation of the guide rod 22.

[0082] In one embodiment, the upper pin mechanism 4.2 and the upper safety device 4.6 are connected to prevent the guide rod 22 from falling due to accidental activation of the upper pin mechanism 4.2. This prevents the guide rod 22 from falling off and causing a dangerous accident if the upper pin mechanism 4.2 is not in place during operation.

[0083] In one embodiment, the upper pin mechanism 4.2 includes an upper holding cylinder and an upper holding pin connected to the upper holding cylinder, the upper holding pin being arranged radially along the upper through hole; the upper safety device 4.6 includes an upper holding limit shaft, an upper sleeve sleeved on the outer periphery of the upper holding limit shaft, and an upper holding return spring embedded in the upper sleeve, one end of the upper holding limit shaft being vertically inserted into the upper holding pin, the other end of the upper holding limit shaft being used to connect to a rope for manual control by the operator, and the upper holding return spring being used to drive the upper holding limit shaft to return to its original position.

[0084] It should be noted that the upper retainer 4 is connected to the pulley block via the hoisting wire rope of the gooseneck 1 for lifting and lowering operations. Since the upper retainer 4 also adopts an openable design, it is used for lifting the guide rod 22 during overall installation. The inner wall of the upper through hole of the upper retainer 4 has three raised upper key strips 4.3 to prevent the vibrator 20 and the guide rod 22 from rotating. Three sets of upper pin mechanisms 4.2 are installed on the top of the upper retainer 4, controlled by an upper retaining cylinder. These mechanisms extend and retract, thereby locking the guide rod 22 and lifting and lowering it. One set of upper pin mechanisms 4.2 is equipped with an upper safety device 4.6 with the same design as the lower retainer. Before the upper retaining pin retracts, the operator must pull down the upper retaining limit shaft using a rope to remove it from the upper retaining pin (the upper retaining return spring can automatically reset), allowing the upper retaining cylinder to operate. This prevents the guide rod 22 from falling off if the upper pin mechanism 4.2 is not in place during operation.

[0085] In one embodiment, the guide rod 22 comprises multiple detachably connected tubular sections. The topmost section has a top plate. Cables and water / gas pipes are housed inside the guide rod 22. The top plate has a pipe guide to constrain the length of the cables and water / gas pipes inside the guide rod 22. Specifically, the guide rod 22 connects to the vibratory compactor 20. The main body of the guide rod 22 is designed with tubular material, and cables, water / gas pipes, etc., are arranged inside the guide rod 22. The guide rod 22 is mainly composed of tubular materials of different standard lengths connected by flange bolts. The top plate has a pipe guide to constrain the length of the cables, water / gas pipes, etc., inside the guide rod 22. Furthermore, the outer periphery of the guide rod 22 has a groove to cooperate with the pin mechanism of the upper retainer 4 and the lower retainer 21 for relative fixation.

[0086] To further illustrate the installation sequence and usage method of the integrated drilling and vibratory compaction equipment provided by the present invention, an example is given below. The guide rod 22 of this device is approximately 60 meters long and consists of 6 sections of pipe structure, each 10 meters long, connected in sequence by bolts.

[0087] 1. Keep the upper movable part 4.1 as follows Figure 17 Install the guide rod 22 to the corresponding position as shown, and then install the retainer 4 at the bottom of the retainer 4 to lock the guide rod 22 in the corresponding slot.

[0088] 2. Connect the pulley block extending from the winch head 1 to the upper retainer 4, and connect the upper retainer 4 and lower retainer 21 to the first guide rail 3.1 of the column 3 via a gripper structure. Connect the hydraulic circuits of the pin cylinders of the upper retainer 4 and lower retainer 21 to open the pin mechanism of the upper retainer 4 and lower retainer 21, causing the pins to retract. Use relevant auxiliary equipment to lift the guide rod 22 to below the upper retainer 4, and use the upper connecting pin 4.5 to connect the upper retaining movable part 4.1 and the upper retaining fixed part 4.10 to achieve... Figure 10 state.

[0089] 3. Remove the suspension point of the second guide rod 22, use a winch to lift the upper retainer 4, and continue to suspend the fifth guide rod 22 using relevant auxiliary equipment to prevent the guide rod 22 from touching the bottom and damaging the water and gas pipes and cables. When the guide rod 22 reaches a near-vertical position, use the auxiliary winch 9 to lift the lower retainer 21, allowing the guide rod 22 to pass through the lower retainer 21. The pin mechanism of the lower retainer 21 closes, meaning the pin of the lower retainer 21 extends and locks the guide rod 22, achieving the desired result. Figure 20 The state shown.

[0090] 4. Install the vibratory compactor and buffer device. First, connect the buffer device, then place the vibratory compactor directly below it. Connect the cable and water / air pipe of the vibratory compactor 20 to achieve the desired effect. Figure 22 The state shown.

[0091] 5. Open the lower pin mechanism 21.2 of the lower retainer 21, causing the pin of the lower retainer 21 to retract. The upper retainer 4 clamps the guide rod 22 and performs a lowering operation. When the upper retainer 4 falls close to the lower retainer 21, close the lower pin mechanism 21.2 of the lower retainer 21, causing the lower retaining pin 21.2.2 to extend and lock into the corresponding position on the second guide rod, achieving the desired effect. Figure 23The state is shown. Remove the retaining plate 4.9 of the upper retainer 4 and connect the upper retaining movable part 4.1 and the upper retaining fixed part 4.10. At this time, the two retainers are close together, and the upper retainer 4 can be separated from the guide rod 22. The wire rope pulls the upper retainer 4 to move along the guide rod 22. When the upper retainer 4 moves to the top of the guide rod 22, fix the upper retainer 4 and the guide rod 22, and separate the lower retainer 21 from the guide rod 22 so that the guide rod 22 can be moved up and down by pulling the wire rope, avoiding the guide rod 22 from extending too far out of the upper retainer 4, so that the guide rod 22, which is higher than the overall position of the machine, can be inserted into the hole to the required depth. Among them, the upper retainer 4 and the lower retainer 21 each have a set of pin devices with safety devices. Before each opening of the retainer's pin mechanism, the operator must pull the lower retaining limit shaft 21.2.3 or the upper retaining limit shaft to disengage it from the hole on the pin, so that the corresponding pin can retract.

[0092] 6. Install the power head 2 onto the second guide rail 3.2 of the column 3 via the pulley block extending from the winch. Then connect the auger drill rod 23 to the power head 2 to achieve the desired result. Figure 24 The state shown is as follows. Furthermore, a suitable number of standard sections of auger drill rod can be installed according to the actual construction depth, and corresponding pre-hole retainers 19 can be installed to prevent significant deviations in the trajectory of the auger drill rod during use.

[0093] The device's column 3 is equipped with double guide rails, integrating pre-drilling and vibratory compaction methods. This results in high operational efficiency, enabling single-pile pre-drilling and vibratory compaction without machine displacement, thus preventing hole collapse. Furthermore, the unique opening and closing structure of the upper retainer 4 facilitates the lifting and installation of the entire guide rod 22. Both the upper retainer 4 and the lower retainer 21 employ an opening and closing design, working together to facilitate the installation and use of the guide rod 22, ensuring its verticality and consequently the drilling accuracy of the vibratory compactor 20. Moreover, this device can be used with a large-platform walking chassis. The platform offers ample space (allowing for the installation of the diagonal bracing assembly 5, hydraulic pump station 7, operator's cab 10, and lifting mechanism 18 on the pile frame 26), integrating multiple working systems. The walking chassis ensures high overall safety and stability.

[0094] It should be noted that the first guide rail 3.1 and the second guide rail 3.2 mentioned in this invention are only distinguished by their different positions and do not have any order of precedence.

[0095] In addition, it should be noted that the orientation or positional relationship indicated by "up and down", "vertical", "horizontal" etc. in this invention is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the purpose of simplifying the description and making it easier to understand, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.
