Description

Technical Field

[0001] This application relates to the technical field of steel pipe piles, especially the method for pilot hole drilling and driving of steel pipe piles in rivers with complex mountainous geology. Background Art

[0002] In recent years, with the rapid development of bridge technology in China, the number of bridges across large rivers has been increasing continuously. As the transportation lifeline for bridge construction materials and equipment, steel trestles are increasingly used in projects. Under different hydrological and geological conditions, especially in the face of harsh conditions such as complex mountainous areas and rivers, the design and construction of steel trestles have become the key to project success.

[0003] When constructing a steel trestle, the foundation is supported by steel pipe piles. During the construction of steel pipe piles, a drill bit is first used to drill a mounting hole in the roadbed, and then the steel pipe pile is installed into the mounting hole. In order to improve the verticality of the steel pipe pile, positioning is required during both the drilling and installation processes of the steel pipe pile. Therefore, the positioning process takes a relatively long time, reducing the construction efficiency. Moreover, since the drill bit is in a rotating state, the positioning effect is poor, reducing the construction quality. Summary of the Invention

[0004] In order to improve the construction efficiency and quality, this application provides a method for pilot hole drilling and driving of steel pipe piles in rivers with complex mountainous geology.

[0005] The method for pilot hole drilling and driving of steel pipe piles in rivers with complex mountainous geology provided by this application adopts the following technical solutions:

[0006] The method for pilot hole drilling and driving of steel pipe piles in rivers with complex mountainous geology includes the following driving steps:

[0007] Step 1: Install the steel pipe pile: Position the steel pipe pile through a guiding device, and then the vibrating hammer vibrates to drive the steel pipe pile into the roadbed or river. At the same time, the guiding device is used to guide and position the position of the steel pipe pile until the installation is in place;

[0008] Step 2: Pilot hole drilling: Use a drilling rig to drill a pilot hole in the soil of the roadbed or river inside the steel pipe pile, and at the same time clean the debris inside the steel pipe pile;

[0009] Step 3: Repeat the above steps to complete the construction of multiple pilot holes for steel pipe piles.

[0010] By adopting the above technical solutions, the hoisted steel pipe pile moves and is connected to the guiding device, and the bottom end of the steel pipe pile presses against the roadbed or is inserted into the river, so as to realize the positioning of the position of the steel pipe pile. Then, the vibrating hammer is connected to the steel pipe pile, and the vibrating hammer vibrates to drive the steel pipe pile into the roadbed or river. At the same time, the guiding device is used to guide and position the position of the steel pipe pile, thereby improving the convenience and accuracy of steel pipe pile positioning, and improving the construction efficiency and quality;

[0011] After the steel pipe pile is installed, it is disassembled from the vibratory hammer. Then, the drilling rig is started to drill a hole inside the steel pipe pile. While drilling the hole, the debris inside the steel pipe pile is cleaned, thus realizing the construction of drilling the hole in the steel pipe pile. Therefore, the steel pipe pile can guide the subsequent drilling of the drilling rig, so that the positioning of the steel pipe pile can be achieved only after one positioning. Moreover, when the steel pipe pile is inserted, it is in a non-rotating state, thus improving the convenience and accuracy during positioning, and thereby improving the construction efficiency and quality.

[0012] Optionally, the guiding device includes:

[0013] A frame body, which is placed on the roadbed or inserted into the river;

[0014] A moving component, which is detachably arranged on the frame body and is used to drive the frame body to move on the roadbed;

[0015] A sliding seat, which is arranged on the frame body to slide up and down;

[0016] A lifting component, which is arranged on the frame body and is used to drive the sliding seat to move. After the lifting component is unlocked, the sliding seat and the steel pipe pile move together;

[0017] A clamping mechanism, which is arranged on the sliding seat and is used to clamp the top end of the steel pipe pile.

[0018] By adopting the above technical solution, the moving component is started to drive the frame body to move on the roadbed. The frame body moves to the construction site. The lifting component is started to drive the sliding seat and the clamping mechanism to move up. Then, the steel pipe pile is moved to the clamping mechanism and its bottom end is pressed against the roadbed for positioning. The clamping mechanism is started to clamp the top end of the steel pipe pile. Then, the vibratory hammer is connected to the steel pipe pile. Then, the lifting component is started to unlock the sliding seat. After unlocking, the bottom end of the steel pipe pile is pressed against the roadbed to position the sliding seat and the clamping mechanism. The vibratory hammer vibrates to sink the steel pipe pile into the roadbed. At the same time, the sliding seat and the clamping mechanism move down together until the installation is completed, thus realizing continuous guiding and positioning of the steel pipe pile, so as to maintain the verticality of the steel pipe pile, thereby improving the construction convenience and accuracy, and improving the construction efficiency and quality.

[0019] At the same time, when it is necessary to insert the steel pipe pile into the river, first disassemble the moving component, and then use a crane to hoist the frame body and insert it into the river. Therefore, the steel pipe pile can be inserted into the river.

[0020] Optionally, there are two clamping mechanisms arranged at intervals. The clamping mechanism includes:

[0021] A clamping electric push rod, which is arranged on the sliding seat;

[0022] A mounting plate, which is arranged on the piston rod of the clamping electric push rod;

[0023] Arc-shaped clamping pieces, the arc-shaped clamping pieces are detachably installed on the mounting plate through clamping members, and the two arc-shaped clamping pieces cooperate to clamp and position the top of the steel pipe pile;

[0024] Connection assembly, the connection assembly is arranged on the arc-shaped clamping piece and is used to connect with the vibratory hammer;

[0025] Control assembly, the control assembly is arranged on the frame and is used to control the start and stop of the clamping electric push rod.

[0026] By adopting the above technical solution, the steel pipe pile is moved between the two arc-shaped clamping pieces, the bottom end of the steel pipe pile is pressed against the roadbed for positioning, and then the two clamping electric push rods are started to drive the two arc-shaped clamping pieces to approach and press against the side wall at the top of the steel pipe pile for positioning. Then, the two arc-shaped clamping pieces are connected with the vibratory hammer through the connection assembly, and the vibratory hammer vibrates to drive the steel pipe pile to move down for installation, thereby improving the convenience of installing the steel pipe pile and improving the construction efficiency and quality.

[0027] When the steel pipe pile moves down to the bottom end of the frame, the control assembly starts to drive the two clamping electric push rods to start and drive the two arc-shaped clamping pieces away from the steel pipe pile. Since the arc-shaped clamping piece is connected with the vibratory hammer, the mounting plate is separated from the arc-shaped clamping piece, and the two arc-shaped clamping pieces continue to clamp the steel pipe pile. Therefore, the vibratory hammer can continue to drive the steel pipe pile to move down to complete the installation of the steel pipe pile. After the installation is completed, the connection assembly is unlocked to remove the two arc-shaped clamping pieces, and finally the two arc-shaped clamping pieces are installed on the two mounting plates through the clamping members, so that the subsequent installation of the steel pipe pile can be continued;

[0028] When the steel pipe pile moves down to the bottom end of the frame, the installation is almost completed. At this time, most of the steel pipe pile has been inserted into the roadbed. At this time, the perpendicularity required for the installation of the steel pipe pile can be achieved without guidance, and it is not necessary to disconnect the arc-shaped clamping piece from the vibratory hammer and then reconnect it to the steel pipe pile to complete the final installation of the steel pipe pile, while improving the construction quality and efficiency.

[0029] Optionally, the connection assembly includes:

[0030] Positioning plate, the positioning plate is arranged on the arc-shaped clamping piece and presses against the top of the steel pipe pile for positioning;

[0031] Connecting plate, the connecting plate is arranged on the positioning plate and is used to connect with the vibratory hammer.

[0032] By adopting the above technical solution, the arc-shaped clamping piece is pressed against the side wall at the top end of the steel pipe pile for positioning, and then the connecting plate is connected to the vibrating hammer. Therefore, when the vibrating hammer vibrates, it drives the connecting plate, the positioning plate, the arc-shaped clamping piece and the steel pipe pile to move simultaneously. The positioning plate is pressed against the top end, so the probability of the arc-shaped clamping piece slipping downward under the action of the structural gravity on the sliding seat and the sliding seat is reduced, thereby realizing the connection between the steel pipe pile and the vibrating hammer. At the same time, the clamping effect of the clamping mechanism on the steel pipe pile is improved, and the construction quality is improved.

[0033] Optionally, the control assembly includes:

[0034] A positioning table, which is arranged at the bottom end of the frame body, and the sliding seat is initially supported on the positioning table for positioning;

[0035] An inductor, which is arranged on the positioning table and electrically connected to the clamping electric push rod, and the sliding seat forms an extrusion on the inductor when it is located on the positioning table.

[0036] By adopting the above technical solution, when the sliding seat moves down to the bottom end, it is pressed against the positioning table for positioning. At this time, the sliding seat presses against the inductor for induction. Therefore, the clamping electric push rod starts to drive the mounting plate away from the steel pipe pile, improving the timeliness and accuracy when controlling the mounting plate to disengage. Moreover, it supports the sliding seat, reducing the long-term pulling force exerted by the sliding seat and the structure on the lifting assembly, improving the service life of each structure and the stability during operation, and further improving the construction efficiency.

[0037] When the sliding seat moves up and disengages from the inductor, when the sliding seat moves up to the specified position, the clamping electric push rod starts to drive the arc-shaped clamping piece to clamp the steel pipe pile, thereby improving the convenience during operation and the construction quality.

[0038] Optionally, an auxiliary assembly for assisting in clamping the steel pipe pile is arranged on the frame body and below the sliding seat. The auxiliary assembly includes:

[0039] Two auxiliary electric push rods, which are arranged on the frame body and electrically connected to the inductor;

[0040] Two arc-shaped clamping plates, which are respectively arranged on the piston rods of the two auxiliary electric push rods and are pressed against each other to form a guiding ring. The steel pipe pile slides through the guiding ring for guiding. At the same time, when the two arc-shaped clamping plates move away from each other, the vibrating hammer and the steel pipe pile can pass through.

[0041] By adopting the above technical solution, when the steel pipe pile is moved between the two arc-shaped clamping pieces, it is also between the two arc-shaped clamping plates. When the clamping electric push rod is started to drive the two arc-shaped clamping pieces to clamp the steel pipe pile, the two auxiliary electric push rods are started simultaneously to drive the two arc-shaped clamping plates to approach and press against each other to form a guiding ring. The steel pipe pile is located inside the guiding ring, and when the steel pipe pile moves, it slides through the guiding ring, so as to realize that the clamping mechanism and the two arc-shaped clamping plates jointly guide the steel pipe pile, thereby improving the construction efficiency and quality.

[0042] When the vibratory hammer needs to pass through, the two auxiliary electric push rods are started to drive the two auxiliary clamping plates to move away from each other, and then the vibratory hammer can pass through, and the next steel pipe pile can also enter between the two arc-shaped clamping plates.

[0043] Optionally, the lifting assembly includes:

[0044] A collecting tray, which is rotatably arranged on the frame;

[0045] A collecting rope, which is wound on the collecting tray and connected to the sliding seat;

[0046] A collecting motor, which is arranged on the frame and connected to the collecting tray and is used to drive the collecting tray to rotate. At the same time, after the collecting motor unlocks the collecting tray, the up and down movement of the collecting tray is not restricted.

[0047] By adopting the above technical solution, the lifting motor is started to drive the lifting tray to rotate. The rotation of the lifting tray is used to wind the collecting rope, and the collecting rope pulls the sliding seat to move up, so that the sliding seat and the clamping mechanism move up to the designated position. Then, the steel pipe pile is placed, and then the clamping mechanism is started to clamp the steel pipe pile, and the steel pipe pile presses against the roadbed for positioning. Then, the collecting motor is started to unlock its output shaft. Therefore, the output shaft of the collecting motor and the collecting tray can rotate freely, and the sliding seat can move down freely to drive the collecting tray to rotate, thereby improving the convenience of the lifting assembly to drive the sliding seat to move and unlock, and also reducing the probability of damage to the lifting assembly caused by the vibratory hammer driving the sliding seat to vibrate up and down, thereby improving the construction efficiency.

[0048] Optionally, the moving assembly includes:

[0049] A mounting plate, which is detachably mounted on the bottom end of the frame;

[0050] A plurality of moving wheels, which are rotatably arranged on the mounting plate and roll on the roadbed;

[0051] A moving motor, which is arranged on the mounting plate and is used to drive the moving wheels to rotate.

[0052] By adopting the above technical solution, the mobile motor starts to drive the mobile wheel to rotate, so as to drive the frame body and multiple mobile wheels to move simultaneously, thereby realizing the adjustment of the position of the guiding device. When disassembly is required, the disassembly of the mounting plate can realize the disassembly of the mobile assembly.

[0053] Optionally, a plurality of positioning components for positioning are arranged on the frame body, and the positioning components include:

[0054] A positioning electric push rod, which is arranged on the frame body;

[0055] A positioning disk, which is arranged on the piston rod of the positioning electric push rod and abuts against the roadbed for positioning.

[0056] By adopting the above technical solution, after the frame body moves, the positioning electric push rod starts to drive the positioning disk to move down and abut against the roadbed for positioning. When movement is required, the positioning electric push rod starts to drive a plurality of positioning disks to move up and away from the roadbed, thereby realizing the positioning and unlocking of the frame body, further improving the accuracy of the position of the steel pipe pile and the construction quality.

[0057] When the steel pipe pile needs to be inserted into the river, the disassembly of the positioning electric push rod can realize the disassembly of the positioning component, and then the installation steel pipe pile can be inserted into the river.

[0058] Optionally, the frame body includes two mobile frames and a connecting rod. The two mobile frames are located on both sides of the steel pipe pile. The two ends of the connecting rod are connected to the two frame bodies. A passage space for the steel pipe pile to pass through is formed between the two mobile frames and on the side of the mobile frame away from the connecting rod.

[0059] By adopting the above technical solution, the steel pipe pile moves to the clamping mechanism through the passage space, so that it is not necessary to move the whole steel pipe pile above the two clamping mechanisms and then move it down to the clamping mechanism, thereby improving the efficiency of transporting the steel pipe pile and the construction efficiency.

[0060] In summary, the present application includes at least one of the following beneficial technical effects:

[0061] By connecting the steel pipe pile with the guiding device, and then connecting the vibrating hammer with the steel pipe pile, the vibrating hammer vibrates to drive the steel pipe pile to be inserted into the roadbed. At the same time, the guiding device is used to guide and position the position of the steel pipe pile. After the installation of the steel pipe pile is completed, it is disassembled from the vibrating hammer. Then the drill starts to drill a hole in the steel pipe pile. During the hole drilling, the sundries in the steel pipe pile are cleaned, thereby realizing the construction of drilling a hole in the steel pipe pile. Therefore, the steel pipe pile can guide the subsequent drilling of the drill, so that the positioning of the steel pipe pile can be realized only after one positioning, and the steel pipe pile is in a non-rotating state when inserted, thereby improving the construction efficiency and quality.

[0066] The following further elaborates on the present application in conjunction with the attached Figures 1-3 drawings.

[0067] The embodiment of the present application discloses a method for drilling and driving steel pipe piles in a mountainous area with complex geology and rivers.

[0070] Step 2: Drilling: Use a drill to drill holes in the soil in the roadbed or river in the steel pipe pile 1, and at the same time clean the impurities in the steel pipe pile 1. The impurities are generally a mixture of mud or gravel and water. The impurities in the steel pipe pile 1 are cleaned by cooperating a sand pump and a suction pipe. This is a common means in the prior art and will not be elaborated here;

[0071] Step 3: Repeat the above steps to complete the construction of drilling holes for multiple steel pipe piles 1.

[0072] Referring to Figure 1 andFigure 2 The guiding device 2 is located around the insertion point of the steel pipe pile 1. The guiding device 2 includes a frame body 21 and a moving component 23. The frame body 21 moves on the roadbed. The frame body 21 includes two moving frames 211 and a connecting rod 212. The two moving frames 211 are located on both sides of the insertion point of the steel pipe pile 1 and are vertically placed; the connecting rod 212 is in a horizontal state and is provided with a plurality of vertical intervals. Both ends of the plurality of connecting rods 212 are fixedly connected to the two moving frames 211 respectively, so as to realize the fixed connection of the two moving frames 211 together.

[0073] The moving component 23 is arranged on the frame body 21 and is used to drive the frame body 21 to move. The moving component 23 includes a mounting plate, a plurality of moving wheels 24, and a moving motor 25.

At the same time, the moving motors 25 are arranged on both moving frames 211 and are located on the opposite sides of the two moving frames 211. When it is necessary to insert the frame body 21 into the river, the mounting plate can be disassembled to realize the disassembly of the moving component 23. A passage space 11 is formed between the two moving frames 211 and on the side of the moving frame 211 away from the connecting rod 212. The passage space 11 is for the steel pipe pile 1 to move from the outside of the two moving frames 211 to the inside.

At the same time, an elastic rubber layer 33 is fixedly mounted on the lower surface of the positioning disk 32, and a friction-increasing abrasive layer is arranged on the rubber layer 33. At the same time, when it is necessary to insert the frame body 21 into the river, the bearing plate can be disassembled to realize the disassembly of the positioning component 3.

[0075] The moving motor 25 is started to drive the moving wheel 24 to rotate. The moving wheel 24 rotates to drive the frame body 21 to move. After moving in place, a plurality of positioning electric push rods 31 are started to drive a plurality of positioning disks 32 to press against the roadbed, so as to realize the positioning of the position of the frame body 21. When it is necessary to move, the plurality of positioning disks 32 are driven by the plurality of positioning electric push rods 31 to move away from the roadbed, so as to realize the unlocking of the frame body 21.

[0076] Refer to Figure 2 and Figure 3, the guiding device 2 further includes a sliding seat 22, a lifting assembly 4 and a clamping mechanism 5. There are two sliding seats 22, which are vertically slidably installed on the side walls of the opposite sides of the two moving frames 211 respectively. The two sliding seats 22 are located on both sides of the insertion point of the steel pipe pile 1, and the side walls of the two sliding seats 22 close to the connecting rod 212 are fixedly connected together through a sliding plate 14, so that the two sliding seats 22 move simultaneously; there are two lifting assemblies 4, which are located on the two moving frames 211 and are arranged in one-to-one correspondence with the two sliding seats 22. The lifting assembly 4 is used to drive the sliding seat 22 to move, and after the lifting assembly 4 unlocks the sliding seat 22, the movement of the sliding seat 22 in the vertical direction is not restricted.

[0077] Referring to Figure 2 , the lifting assembly 4 includes a collecting disc 41, a collecting rope 42 and a collecting motor 43. The two collecting discs 41 are horizontally rotatably installed on the opposite side walls of the two moving frames 211, and the collecting disc 41 is located at the bottom end of the moving frame 211; guide wheels 44 are rotatably installed at the top ends of the opposite side walls of the two moving frames 211, and guide wheels 45 are rotatably installed at the top ends of the opposite side walls of the two moving frames 211. The axes of the guide wheel 45, the guide wheel 44 and the collecting disc 41 are parallel, and at the same time, guiding grooves for limiting are coaxially opened on both the guide wheel 45 and the guide wheel 44; one end of the collecting rope 42 is fixedly installed on the collecting disc 41 and wound on the collecting disc 41, and at the same time, the other end of the collecting rope 42 is fixedly connected to the upper surface of the sliding seat 22 after passing around the guide wheel 45 and the guide wheel 44.

[0078] The collecting motor 43 is fixedly installed on the bottom end of the moving frame 211, and the output shaft of the collecting motor 43 is connected to the collecting disc 41. At the same time, the collecting motor 43 can also be fixedly installed on the side wall of the moving frame 211 close to the top end of the moving frame 211 according to needs; when the collecting motor 43 is started, it drives the collecting disc 41 to rotate. The rotation of the collecting disc 41 is used to wind the collecting rope 42, and the movement of the collecting rope 42 pulls the sliding seat 22 to move, so as to realize the movement of the sliding seat 22. When it is necessary to unlock the sliding seat 22, after the collecting motor 43 stops running, the output shaft of the collecting motor 43 is unlocked, so that the output shaft of the collecting motor 43 can rotate freely, thereby realizing the unlocking of the sliding seat 22.

[0079] Referring to Figure 2 and Figure 3, there are two clamping mechanisms 5 arranged oppositely and located on two sliding seats 22. The clamping mechanism 5 includes a clamping electric push rod 51, a mounting plate 52, an arc-shaped clamping piece 53, a connecting component 54, and a control component 6. The clamping electric push rod 51 is fixedly installed on the upper surface of the sliding seat 22, and the piston rod extends horizontally between the two sliding seats 22; the mounting plate 52 is fixedly installed on the piston rod of the clamping electric push rod 51. A plurality of clamping grooves are horizontally spaced on the side walls of the opposite sides of the two mounting plates 52; the arc-shaped clamping piece 53 is detachably installed on the mounting plate 52 through a clamping member, and the arc-shaped clamping piece 53 is located between the two mounting plates 52. The clamping member is a plurality of clamping blocks 12. The clamping blocks 12 are fixedly installed on the side wall of the arc-shaped clamping piece 53 close to the mounting plate 52. The plurality of clamping blocks 12 are arranged in one-to-one correspondence with the plurality of clamping grooves and are clamped and installed in the clamping grooves for positioning. At the same time, the upper and lower surfaces of the arc-shaped clamping piece 53 and the mounting plate 52 are flush and extend to the upper and lower sides of the sliding seat 22 respectively.

[0080] The arc-shaped clamping piece 53 is arc-shaped and fits the outer side wall of the steel pipe pile 1. The two arc-shaped clamping pieces 53 cooperate to clamp the top end of the steel pipe pile 1; the connecting component 54 is arranged on the arc-shaped clamping piece 53 and is used to connect with the vibratory hammer 13. The connecting component 54 includes a positioning plate 55 and a connecting plate 56. The two positioning plates 55 are integrally arranged at the top ends of the opposite side walls of the two arc-shaped clamping pieces 53, and the positioning plate 55 is in a horizontal state and presses against the top end of the steel pipe pile 1 for positioning; the connecting plate 56 is fixedly installed on the upper surface of the positioning plate 55, and the two connecting plates 56 are used to connect with the vibratory hammer 13. At the same time, the connecting plate 56 is a plate-shaped structure, and the vibratory hammer 13 contacts the arc surface of the steel pipe pile 1. The plate-shaped structure of the connecting plate 56 improves the convenience and stability during the connection of the vibratory hammer 13.

[0081] The control component 6 is arranged on the moving frame 211 and is used to control the start and stop of the clamping mechanism 5. There are two control components 6 and they are arranged in one-to-one correspondence with the two sliding seats 22; the control component 6 includes a positioning table 61 and a sensor 62. The two positioning tables 61 are fixedly installed at the bottom ends of the opposite side walls of the two moving frames 211. When the sliding seat 22 slides down to the lowest position, the lower surface of the sliding seat 22 supports on the positioning table 61 for positioning. At the same time, the sliding seat 22 is initially located at the positioning table 61; an installation groove is opened on the upper surface of the positioning table 61, and the sensor 62 is fixedly installed in the installation groove. A control board for controlling the start and stop of the clamping electric push rod 51 is fixedly installed on the moving frame 211, and the sensor 62 is electrically connected to the control board; when the sliding seat 22 supports on the positioning table 61, the sliding seat 22 presses the sensor 62, and the sensor 62 controls the clamping electric push rod 51 to drive the arc-shaped clamping piece 53 away from the steel pipe pile 1 through the control board.

[0082] Refer to Figure 2 and Figure 3, the sliding seat 22 moves upward to drive the clamping mechanism 5 to move upward to the designated position. Then, the steel pipe pile 1 enters the inner sides of the two moving frames 211 through the passage space 11 until the steel pipe pile 1 moves to the insertion point. At this time, the steel pipe pile 1 enters between the two arc-shaped clamping pieces 53, and the bottom end of the steel pipe pile 1 presses against the roadbed. Then, the two clamping electric push rods 51 are activated to make the two arc-shaped clamping pieces 53 approach each other and press against the top end of the steel pipe pile 1, while the two positioning plates 55 press against the top end of the steel pipe pile 1 for positioning. Then, the vibratory hammer 13 approaches the connecting plate 56 and is fixedly connected to the connecting plate 56, so as to connect the steel pipe pile 1, the sliding seat 22, the clamping mechanism 5, and the vibratory hammer 13 together. The bottom end of the steel pipe pile 1 presses against the roadbed for positioning.

[0083] The collecting motor 43 unlocks the sliding seat 22, and the vibration of the vibratory hammer 13 causes the steel pipe pile 1, the sliding seat 22, and the clamping mechanism 5 to move downward simultaneously. When the sliding seat 22 presses against the positioning table 61, the sliding seat 22 squeezes the inductor 62, and the clamping electric push rod 51 is activated to drive the two arc-shaped clamping pieces 53 away from the steel pipe pile 1. Since the arc-shaped clamping pieces 53 are connected to the vibratory hammer 13, the mounting plate 52 is separated from the arc-shaped clamping pieces 53, and the vibratory hammer 13 continues to drive the steel pipe pile 1 to continue to sink until the installation is completed. Then, the two connecting plates 56 are disassembled from the vibratory hammer 13, and finally, the arc-shaped clamping pieces 53 are fixedly installed on the mounting plate 52, so that the installation of the steel pipe pile 1 can be continued.

[0084] Refer to Figure 2 , auxiliary components 7 for assisting in clamping the steel pipe pile 1 are provided at the bottom ends of the two moving frames 211. The auxiliary components 7 are located below the clamping mechanism 5; the auxiliary components 7 include two auxiliary electric push rods 71 and two arc-shaped clamping plates 72. The two auxiliary electric push rods 71 are fixedly installed on the bottom ends of the two moving frames 211. The two auxiliary electric push rods 71 are located below the positioning table 61 and are arranged oppositely; the two arc-shaped clamping plates 72 are fixedly installed on the piston rods of the two auxiliary electric push rods 71, and the two arc-shaped clamping plates 72 abut against each other to form an annular guiding ring. At the same time, the bottom end of the steel pipe pile 1 slides through the guiding ring for guiding and positioning, so as to realize the guiding and positioning of the steel pipe pile 1; at the same time, the auxiliary electric push rod 71 is electrically connected to the control board, so as to realize the start and stop control of the auxiliary electric push rod 71. When the sliding seat 22 moves downward to the positioning table 61 and squeezes the inductor 62, the control board simultaneously activates the two auxiliary electric push rods 71 to drive the two arc-shaped clamping plates 72 to move away from each other, so as to facilitate the passage of the vibratory hammer 13 and facilitate the subsequent entry of the next steel pipe pile 1 between the two arc-shaped clamping plates 72.

[0085] The working principle of the embodiment of the present application is:

[0086] The sliding seat 22 moves upward to drive the clamping mechanism 5 to move upward to the designated position. Then, the steel pipe pile 1 is moved to the insertion point, and the bottom end of the steel pipe pile 1 presses against the roadbed. Then, the two clamping electric push rods 51 are activated to drive the two arc-shaped clamping pieces 53 to press against the side wall of the steel pipe pile 1, while the two positioning plates 55 press against the top end of the steel pipe pile 1. At the same time, the two auxiliary electric push rods 71 are activated to drive the two arc-shaped clamping plates 72 to approach each other and press together to form a guiding ring. Then, the two connecting plates 56 are connected to the vibratory hammer 13. The bottom end of the steel pipe pile 1 presses against the roadbed for positioning. Then, the collecting motor 43 unlocks the sliding seat 22. The vibratory hammer 13 vibrates, causing the steel pipe pile 1, the sliding seat 22, and the clamping mechanism 5 to move downward simultaneously, and the steel pipe pile 1 slides through the guiding ring for guiding and positioning. When the sliding seat 22 presses against the positioning table 61, the sliding seat 22 presses the inductor 62. The clamping electric push rod 51 is activated to drive the two arc-shaped clamping pieces 53 to separate from the mounting plate 52. At the same time, the two auxiliary electric push rods 71 are activated to drive the two arc-shaped clamping plates 72 to move away from each other. Then, the vibratory hammer 13 continues to drive the steel pipe pile 1 to sink until the installation is completed. Then, the two connecting plates 56 are disassembled from the vibratory hammer 13. Finally, the arc-shaped clamping pieces 53 are installed on the mounting plate 52.

[0087] Then, a drill is used to drill a hole in the roadbed inside the steel pipe pile 1, and the debris generated during the drilling is cleaned while drilling, so as to realize drilling and hole cleaning, and thus realize the hole drilling construction of the steel pipe pile 1. Then, the above steps can be repeated to complete the entire hole drilling construction of the steel pipe pile 1, thereby improving the construction quality and efficiency.

[0088] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
