[0072] Example 1

[0073] This embodiment provides a wharf structure construction method according to the present application, which includes the following steps: lifting the steel pipe 1 and setting it vertically by the first lifting device, then driving the steel pipe 1 to the predetermined position, cutting off the excess part of the upper part of the steel pipe 1 to form the remaining steel pipe section 11, and lifting the remaining steel pipe section 11 away by the first lifting device;

[0074] A preferred method is to drive the steel pipe 1 to a predetermined position, treat the inside of the steel pipe 1, and inspect the bottom inside of the steel pipe 1 using a detection system.

[0075] A preferred method is to process a reinforcing cage 3, place at least a portion of the reinforcing cage 3 into the steel pipe 1, and use a cage clamping device to position the relative depth between the bottom of the reinforcing cage 3 and the steel pipe 1, and then pour concrete into the steel pipe 1 to form a steel pipe pile.

[0076] A preferred method: a bracket 4 is welded to the outside of the steel pipe 1 by a steel pipe pile working platform, at least part of the structure on the bracket 4 is formed by splitting the remaining steel pipe section 11, and the steel pipe pile working platform can move laterally relative to the steel pipe 1;

[0077] A preferred method: rock-filling construction is carried out around the steel pipe pile using a second lifting device;

[0078] A preferred method is to erect a formwork system on the corbel 4 to form a beam grid, place steel bars in the beam grid, and pour concrete to form horizontal and vertical beams.

[0079] like Figures 1-5 As shown, in a preferred embodiment: at least three through holes are circumferentially opened at one end of the steel pipe 1, of which the three are the first through hole 111, the second through hole 112 and the third through hole 113, and all are located on the remaining steel pipe section 11;

[0080] The first lifting device includes a first lifting rope assembly and a second lifting rope assembly. The first lifting rope assembly includes a first main rope 101, and the lower end of the first main rope 101 is connected to a first lifting rope 103 and a second lifting rope 104. The second lifting rope assembly includes a second main rope 102, and the lower end of the second main rope 102 is connected to a third lifting rope 105, a fourth lifting rope 106 and a fifth lifting rope 107. The free end of the third lifting rope 105 is connected to a first hook 108, the free end of the fourth lifting rope 106 is connected to a second hook 109, and the free end of the fifth lifting rope 107 is connected to a third hook 110.

[0081] The process of lifting and vertically setting the steel pipe 1 using the first lifting device includes the following steps: A1: Inserting the first hook 108 into the first through hole 111, the second hook 109 into the second through hole 112, and the third hook 110 into the third through hole 113, and hooking the first hook 108, the second hook 109, and the third hook 110 together, and wrapping and fixing the first lifting rope 103 and the second lifting rope 104 around and fixing them to the other end of the steel pipe 1; A2: Changing the steel pipe 1 from horizontal to vertical by lifting the second lifting rope assembly first and then lifting the first lifting rope assembly, or by lifting the second lifting rope assembly faster than the first lifting rope assembly;

[0082] The process of lifting the remaining steel pipe section 11 using the first lifting device includes the following steps: A3: lowering the third lifting rope 105, the fourth lifting rope 106 and the fifth lifting rope 107 from inside the steel pipe 1, and hanging the first hook 108 in reverse at the first through hole 111, the second hook 109 in reverse at the second through hole 112, and the third hook 110 in reverse at the third through hole 113; A4: lifting the second lifting rope assembly to move the remaining steel pipe section 11 away.

[0083] During construction, the steel pipe 1 is changed from a horizontal to a vertical state by first lifting the second lifting rope assembly and then lifting the first lifting rope assembly, or by lifting the second lifting rope assembly faster than the first lifting rope assembly, so that the steel pipe 1 can be placed on the piling equipment. In the above process, since the first hook 108, the second hook 109 and the third hook 110 are hooked together inside the steel pipe 1, and the first lifting rope 103 and the second lifting rope 104 are wrapped and fixed to the other end of the steel pipe 1, no lifting lugs are set on the outside of the steel pipe 1 throughout the process, thus fundamentally avoiding the problem of interference between the lifting lugs and the outer hoop equipment, as well as the problem of the lifting lugs being easily deformed by collision.

[0084] like Figure 4 As shown, during the later pile cutting process, the third lifting rope 105, the fourth lifting rope 106, and the fifth lifting rope 107 are lowered from inside the steel pipe 1. The first hook 108 is hung in reverse at the first through hole 111, the second hook 109 is hung in reverse at the second through hole 112, and the third hook 110 is hung in reverse at the third through hole 113. This allows construction workers to lift the cut portion of the steel pipe 1 by simply pulling out the hooks through the first through hole 111, the second through hole 112, and the third through hole 113. This makes the steel pipe pile lifting device of this application not only usable for lifting the steel pipe 1, but also for lifting and moving the remaining steel pipe section 11 cut off during pile cutting, thus making the second lifting rope assembly of this application more versatile.

[0085] The center of gravity of the steel pipe 1 is located between the first lifting rope assembly and the second lifting rope assembly; the first lifting rope 103 and the second lifting rope 104 are wound in opposite directions to reduce the swing amplitude of the steel pipe 1 during lifting; the first through hole 111 and the third through hole 113 are coaxially correspondingly arranged; this enables the friction between the parts of the third lifting rope 105 and the fifth lifting rope 107 located on the outside of the steel pipe 1 and the outer wall of the steel pipe 1 to be reduced or avoided during the lifting of the steel pipe 1, thereby effectively extending the service life of the third lifting rope 105 and the fifth lifting rope 107.

[0086] like Figures 5-8 As shown, in another preferred embodiment, the steel pipe 1 has two through holes arranged opposite to each other, namely a first through hole 111 and a second through hole 112; the first lifting device includes a first lifting rope assembly, a second lifting rope assembly, and an auxiliary lifting assembly 114; the first lifting rope assembly includes a first main rope 101, and a first lifting rope 103 and a second lifting rope 104 are connected to the lower part of the first main rope 101; the second lifting rope assembly includes a second main rope 102, and a third lifting rope 105 and a fourth lifting rope 106 are connected to the lower part of the second main rope 102; the lower end of the third lifting rope 105 is provided with a first lifting ring 115 and a second lifting ring 116, and the lower end of the fourth lifting rope 106 is provided with a third lifting ring 117, and the first lifting ring 115... The first through hole 111 is extended into the second through hole 112, and the second lifting ring 116 extends into the first through hole 111; the third lifting ring 117 extends into the second through hole 112. The auxiliary lifting assembly 114 includes an auxiliary lifting rope 118, and an auxiliary pin 119 is connected to the end of the auxiliary lifting rope 118. The auxiliary pin 119 can pass through the first lifting ring 115, the second lifting ring 116 and the third lifting ring 117, and can lock the third lifting ring 117 between the first lifting ring 115 and the second lifting ring 116 when the third lifting rope 105 and the fourth lifting rope 106 are tensioned. When the auxiliary lifting rope 118 applies a pulling force to the auxiliary pin 119, the auxiliary pin 119 can disengage from the first lifting ring 115, the second lifting ring 116 and the third lifting ring 117.

[0087] The construction method includes the following steps: B1. Insert the first lifting ring 115 and the second lifting ring 116 into the first through hole 111, and the third lifting ring 117 into the second through hole 112. The third lifting ring 117 is positioned between the first lifting ring 115 and the second lifting ring 116. Insert the auxiliary pin 119 from one end of the steel pipe 1 into the steel pipe 1, and pass the auxiliary pin 119 sequentially through the first lifting ring 115, the third lifting ring 117, and the second lifting ring 116. Then, tighten the third lifting rope 105 and the fourth lifting rope 106 so that one side of the auxiliary pin 119 is pressed against the first lifting ring 115 and the second lifting ring 116, and the other side is pressed against the third lifting ring 117. Wrap and fix the first lifting rope 103 and the second lifting rope 104 around the other end of the steel pipe 1; B 2. The steel pipe 1 is changed from horizontal to vertical by first lifting the second lifting rope assembly and then lifting the first lifting rope assembly, or by lifting the second lifting rope assembly faster than the first lifting rope assembly, and is then lifted to a predetermined position and fixed; B3. The third lifting rope 105 and the fourth lifting rope 106 are in a slack state; B4. The auxiliary lifting assembly 114 is raised, so that the auxiliary lifting rope 118 drives the auxiliary pin 119 to rotate vertically and move upward, so that the auxiliary pin 119 disengages from the first lifting ring 115, the second lifting ring 116 and the third lifting ring 117, until the auxiliary pin 119 is lifted out of the steel pipe 1; B5. The second lifting rope assembly is raised, and the first lifting ring 115 is pulled out from the first through hole 111, and the second lifting ring 116 is pulled out from the second through hole 112.

[0088] This embodiment describes a method for lifting steel pipes for steel pipe piles. The steel pipe 1 is lifted to a predetermined position using a first lifting rope assembly and a second lifting rope assembly. Then, the auxiliary pin 119 of the auxiliary lifting assembly 114 is used to disengage the auxiliary pin 119, the first lifting ring 115, the second lifting ring 116, and the third lifting ring 117. This achieves the automatic disengagement of the second lifting rope assembly at the upper part of the steel pipe 1 from the steel pipe 1. Furthermore, the entire process only requires a first through hole 111 and a second through hole 112 at one end of the steel pipe 1, without the need for lifting lugs on the outside of the steel pipe 1. This avoids interference between the lifting lugs and the outer hoop equipment, reducing the impact of the lifting process on the downward movement of the steel pipe 1.

[0089] During the later pile cutting process, the first lifting ring 115, the second lifting ring 116, and the third lifting ring 117 are inserted into the steel pipe 1 from the top. Then, the first lifting ring 115 and the second lifting ring 116 are extended out of the first through hole 111, and the third lifting ring 117 is extended out of the second through hole 112, so that the third lifting ring 117 is positioned between the first lifting ring 115 and the second lifting ring 116. Then, the auxiliary pin 119 is passed through the first lifting ring 115, the third lifting ring 117, and the second lifting ring 116 in sequence, and then the pile is lifted.

[0090] Furthermore, in step B1, when the auxiliary pin 119 is pressed against the first lifting ring 115 and the second lifting ring 116 on one side and against the third lifting ring 117 on the other side, it can effectively ensure that the auxiliary pin 119 does not detach from the first lifting ring 115, the second lifting ring 116 and the third lifting ring 117 during the lifting process, thereby ensuring the construction safety of the lifting process.

[0091] The auxiliary pin 119 is provided with a first recess 120 that mates with the first lifting ring 115; the auxiliary pin 119 is provided with a second recess 121 that mates with the second lifting ring 116; and the auxiliary pin 119 is provided with a third recess 122 that mates with the third lifting ring 117. This further effectively ensures that the auxiliary pin 119 does not disengage from the first lifting ring 115, the second lifting ring 116, and the third lifting ring 117 during the lifting process, thereby ensuring construction safety during the lifting process.

[0092] like Figure 8 As shown, the auxiliary pin 119 includes a shaft body 123. One end of the shaft body 123 along the axial direction is connected to the auxiliary lifting rope 118, and the other end of the shaft body 123 along the axial direction is connected to a shaft end structure 124. The shaft end structure 124 can pass through the first lifting ring 115, the second lifting ring 116 and the third lifting ring 117. At least one side of the shaft end structure 124 protrudes radially from the shaft body 123 along the auxiliary pin 119.

[0093] During the lifting process, the third lifting rope 105 and the fourth lifting rope 106 are tensioned. One side of the auxiliary pin 119 is pressed against the first lifting ring 115 and the second lifting ring 116, and the other side of the auxiliary pin 119 is pressed against the third lifting ring 117. Under these conditions, at least one side of the shaft end structure 124 protrudes radially from the shaft body 123 along the auxiliary pin 119, which can further ensure that the auxiliary pin 119 does not detach from the first lifting ring 115, the second lifting ring 116 and the third lifting ring 117 during the lifting process, thereby better ensuring the construction safety of the lifting process.

[0094] The shaft end structure 124 is a frustoconical structure, and its small end is threaded to the shaft body 123. The diameter of the small end of the shaft end structure 124 is compatible with the diameter of the shaft body 123. The shaft end structure 124 can elastically deform along the axial direction of the shaft body 123.

[0095] like Figure 9As shown, in a preferred embodiment: the detection system includes a cable winding device 204, a detector 202, and a control console 201 connected via a data transmission cable 203; the detector 202 includes a camera 207 and a liquid level sensor 208 suspended below the camera 207, both of which are communicatively connected to the control console 201 via the data transmission cable 203; the cable winding device 204 includes a motor 216, a guide pulley 205, and a drum 206, with the data transmission cable 203 wound around the drum 206, and the motor 216 driving the drum 206 to rotate, allowing the drum 206 to wind and unwind the data transmission cable 203 by rotating forward or backward; the guide pulley 205 is mounted on the top of the steel pipe 1; the control console 201 is equipped with a display screen 209 for displaying the image captured by the camera 207 and the liquid level height detected by the liquid level sensor 208.

[0096] In a preferred manner, the data transmission cable 203 is wound in the forward direction on one side of the reel 206 and in the reverse direction on the other side to achieve the winding and unwinding of the data transmission cable 203.

[0097] like Figure 10 As shown, the camera 207 includes a lens 210, a cylindrical housing 211, and a camera data cable 212. The lens 210 is embedded in one end of the cylindrical housing 211, and the other end of the cylindrical housing 211 is connected to the control console 201 via the camera data cable 212. The liquid level sensor 208 includes a probe 213, a liquid level sensor data cable 215, and a mounting plate 214. The probe 213 is embedded in the middle of the mounting plate 214 and is connected to the control console 201 via the liquid level sensor data cable 215. The edge of the mounting plate 214 is suspended from the cylindrical housing 211. The data transmission cable 203 is an armored cable that wraps around the camera data cable 212 and the liquid level sensor data cable 215.

[0098] The liquid level sensor 208 is connected to the camera 207 by means of a flexible rope 217, so that when the camera 207 and the liquid level sensor 208 move in the well, the liquid level sensor 208 is always suspended directly below the camera 207.

[0099] In a preferred embodiment, the data transmission cable 203 and the cable retraction device 204 together constitute a single-line winch. The data transmission cable 203 includes a first cable and a second cable. One end of the first cable is connected to the detector 202, and the other end is connected to the cable retraction device 204. One end of the second cable is connected to the cable retraction device 204, and the other end is connected to the control console 201. The cable retraction device 204 is equipped with a communication converter, enabling the first cable to establish a communication connection with the second cable.

[0100] The liquid level sensor 208 is used to detect whether there is water at the bottom of the steel pipe 1 and the liquid level, so as to prevent the camera 207 from being directly lowered into the water and causing damage.

[0101] like Figures 11-13 As shown, a preferred embodiment further includes a rebar rotation device; the rebar cage 3 includes two main threaded rebars 301 coaxially connected by a rebar sleeve 303; the rebar rotation device includes a drive device 401 and a clamping mechanism, the clamping mechanism includes a clamp head structure 402 and a clamp wall structure 403 connected to each other, a first rod 404 is connected to the end of the clamp wall structure 403 away from the clamp head structure 402, the first rod 404 and the clamp wall structure 403 are bent at the connection, a universal joint 405 is connected between the end of the first rod 404 away from the clamp wall structure 403 and the output shaft 411 of the drive device 401, the clamp head structure 402 is correspondingly arranged with the output shaft 411, the clamp head structure 402 clamps the main threaded rebar 301 from one side, and the clamp head structure 402 is located at the end of the main threaded rebar 301 away from the rebar sleeve 303;

[0102] The longitudinal bars are rotated by the rebar rotation device so that adjacent main threaded rebars 301 are connected by the rebar sleeve 303.

[0103] During construction, the drive device 401 is installed at the end of the reinforcing bar. Because the first rod 404 bends at the connection with the clamp wall structure 403, the clamp head structure 402 can clamp the reinforcing bar from the side, providing a more stable clamping compared to clamping along the axial direction. Furthermore, a universal joint 405 connects the end of the first rod 404 away from the clamp wall structure 403 to the output shaft 411 of the drive device 401. The torsional force of the output shaft 411 of the drive device 401 is transmitted sequentially to the first rod 404, the clamp wall structure 403, and the clamp head structure 402 through the universal joint 405. The clamp head structure 402... 2. Corresponding to the output shaft 411, the clamp head structure 402 can rotate around the rotation center of the output shaft 411, thereby driving the rebar to rotate. When the rebar rotates and its own weight causes a large rotational deformation, which will cause the end of the rebar to jump, the universal joint 405 can rotate in two directions, so that the clamp head structure 402 can also swing radially along the output shaft 411 within a certain range. This can effectively reduce the clamping force of the clamp head structure 402 to overcome the rebar getting out of the clamp head structure 402, thereby greatly reducing the probability of the end of the rebar getting out of the clamp head structure 402 due to jumping.

[0104] The clamp head structure 402 includes a first clamp head 412 and a second clamp head 413 arranged opposite to each other. A first clamping space 414 and a first opening 415 are formed between the first clamp head 412 and the second clamp head 413. The first opening 415 is arranged radially along the output shaft 411. The first rod 404 and the clamp wall structure 403 together form an arc-shaped structure. The clamp head structure 402 is also provided with a limiting ring 406 protruding from one side of the first rod 404. The limiting ring 406 is coaxially arranged with the output shaft 411 and is rotatably arranged together with the clamp head structure 402. During construction, the end of the rebar is inserted into the limiting ring 406 to reduce the amplitude of the rebar's jump. This also helps to reduce the clamping force used by the clamp head structure 402 to overcome the rebar's escape from the clamp head structure 402, thereby greatly reducing the probability of the rebar's end escaping from the clamp head structure 402 due to jump.

[0105] The limiting ring 406 is connected to the first rod 404. Specifically, the limiting ring 406 is hinged to the first rod 404, allowing the limiting ring 406 to swing towards or away from the output shaft 411. The limiting ring 406 is located between the clamp head structure 402 and the drive device 401. The clamp assembly is located at the end of the main threaded steel bar 301, and the output shaft 411 is coaxially spaced from the main threaded steel bar 301.

[0106] like Figures 14-19 As shown, a preferred embodiment is provided: the cage clamping device includes a first structure 304 and a second structure 305, the first structure 304 and the second structure 305 are connected by a connecting component 306, and a second clamping space 307 is provided between the first structure 304 and the second structure 305. At least one side of the second clamping space 307 is provided with a threaded steel bar 308, and the threaded steel bar 308 is connected to the first structure 304 or the second structure 305.

[0107] The reinforcing cage 3 includes several longitudinally arranged main threaded steel bars 301 and circumferentially arranged connecting steel bars 302. The connecting steel bars 302 are used to connect adjacent main threaded steel bars 301. The connecting steel bars 302 are spaced apart from the cage clamps of the steel pipe pile reinforcing cage 3.

[0108] By utilizing the semi-annular protrusions and grooves on the side of the threaded steel bar 308, it engages with the semi-annular protrusions and grooves on the side of the main threaded steel bar 301 of the steel cage 3 during use. This allows the threaded steel bar 308 to restrict the movement of the main threaded steel bar 301 relative to the first structure 304 and the second structure 305. This ensures that when the first structure 304 and the second structure 305 clamp the main threaded steel bar 301, there is no relative movement between the main threaded steel bar 301 and the first structure 304 and the second structure 305. Consequently, the steel cage 3 does not move relative to the cage clamping device of this application, thus ensuring the relative height between the bottom of the steel cage 3 and the bottom of the steel pipe 1 pile, thereby effectively improving the construction quality of the steel pipe 1.

[0109] Both sides of the second clamping space 307 are provided with threaded steel bars 308, and the first structure 304 and / or the second structure 305 are provided with recessed portions 309, which cooperate with the threaded steel bars 308. This enables precise positioning of the threaded steel bars 308, making it easier to install them.

[0110] The connecting assembly 306 includes at least two bolt assemblies, with a second clamping space 307 located between them. A steel bar 311 connects the bolt heads 310 of the at least two bolt assemblies located on either side of the second clamping space 307. This ensures that the bolt 313 does not rotate when the nut 312 at the other end is tightened, or rotates to a certain angle and then stops rotating, making the installation of the bolt assemblies more convenient. The first structure 304 includes a first plate 314 and a first stiffening plate 315 connected together, with the first stiffening plate 315 connected to the side of the first plate 314 away from the second clamping space 307. The first plate 314 and the first stiffening plate 315 are perpendicular to each other.

[0111] A portion of the reinforcing cage 3 extends into the steel pipe 1. Both the steel pipe 1 and the reinforcing cage 3 are vertically arranged. The reinforcing cage 3 includes several main threaded reinforcing bars 301 arranged along the length of the reinforcing cage 3. At least one main threaded reinforcing bar 301 penetrates the second clamping space 307, and the side of the main threaded reinforcing bar 301 is in concave-convex limiting fit with the threaded reinforcing bar 308. The first structure 304 abuts against the top of the steel pipe 1. The main threaded reinforcing bars 301 and the threaded reinforcing bars 308 have the same diameter.

[0112] like Figures 20-25 As shown, the steel pipe pile working platform includes at least two spaced platform structures 501, with a passage 502 between adjacent platform structures 501. One of the adjacent platform structures 501 is provided with a first slide rail 503, and the other is provided with a second slide rail 504. Both the first slide rail 503 and the second slide rail 504 are arranged along the direction of the passage 502. At least three first sliders 505 are slidably fitted in the first slide rail 503, and at least three second sliders 506 are slidably fitted in the second slide rail 504. The first sliders 505 and the second sliders 506 are arranged correspondingly. Hook locks 507 are connected to both the first sliders 505 and the second sliders 506. The first sliders 505 on the first slide rail 503 can enter and exit the first slide rail 503 from both ends, and the second sliders 506 on the second slide rail 504 can enter and exit the second slide rail 504 from both ends.

[0113] Both ends of the first slide 503 and both ends of the second slide 504 are open; a gantry 508 is fixedly connected between adjacent platform structures 501, and the steel pipe 1 and the bracket 4 can pass through the gantry 508.

[0114] The welding of brackets 4 on the outside of steel pipe 1 using a steel pipe pile working platform includes the following steps: C1: For several steel pipes 1 extending out of the water and distributed linearly, hook locks 507 can be installed on two or three steel pipes 1 using hoisting machinery, and bracket 4 welding operations can be performed on these two or three steel pipes 1, which are located in the channel 502; C2: A pulling device 514 is installed on the steel pipe 1 on one side of the channel 502, and the pulling device 514 is connected to the steel pipe pile working platform. The pulling device 514 drives the steel pipe pile working platform to move until one or more steel pipes 1 in the forward direction of the steel pipe pile working platform enter the channel 502; During this process, the hook locks 507 are pulled by the steel pipes 1, and the hook locks 507 will drag the first slider 505 to slide in the first slide rail 503, and the second slider 506 to slide in the second slide rail 504, thereby maintaining the hook locks 507 and the steel pipes 1 in the hooked state during the movement of the steel pipe pile working platform. C3: During the movement of the steel pipe pile working platform, when the steel pipe 1 located at the rear end of the steel pipe pile working platform in the forward direction corresponds to the end position of the first slide rail 503 and the second slide rail 504, the hook lock 507 connected to the steel pipe 1 and the corresponding first slider 505 and second slide rail 504 are removed and installed on the steel pipe 1 that enters the channel 502 from the front end of the steel pipe pile working platform in the forward direction. C4: Repeat steps C1-C3 until the bracket 4 is welded.

[0115] At least three first sliders 505 are slidably fitted within the first slide rail 503, and at least three second sliders 506 are slidably fitted within the second slide rail 504. The first sliders 505 and second sliders 506 are correspondingly arranged, and each of the first sliders 505 and second sliders 506 is connected to a hook lock 507. The hook lock 507 can be used to hook the top of the steel pipe 1, thereby providing support for the steel pipe pile working platform. The at least four hook locks 507 distributed on both sides of the channel 502 can relatively stably suspend and fix the steel pipe pile working platform to the steel pipe 1, thereby forming a support for the steel pipe 1. The working platform; through the sliding engagement of the first slider 505 and the first slide rail 503, and the sliding engagement of the second slider 506 and the second slide rail 504, the end of the hook lock 507 near the platform structure 501 can move relative to the platform structure 501. In this way, the platform structure 501 can move relative to the steel pipe 1 to travel to the next working area, and maintain the hooking state with the steel pipe 1 during the movement. Thus, the working platform can be flexibly and conveniently formed between multiple steel pipes 1 through the movement of the steel pipe pile working platform, so as to realize the processing operation of several steel pipes 1.

[0116] The steel pipe pile working platform of the present invention can be used to provide a working platform for a number of steel pipe piles 3 arranged in a straight line. In use, the steel pipe pile working platform can be suspended on two adjacent steel pipe piles 3 by at least four hook locking pieces 507 to form a working platform for the two steel pipe piles 3. After the operation is completed, the steel pipe pile working platform is pushed and pulled to move it in the first direction, so that the next steel pipe pile 3 enters the steel pipe pile working platform along the channel 502 to form a working platform for the next steel pipe pile 3. The pulling equipment 514 is preferably a hand chain hoist, winch, etc.

[0117] During the movement of the steel pipe pile working platform, the first slider 505 and the second slider 506, which slide out from the rear end of the moving direction, can be used to connect with the next steel pipe 1 and re-enter the slide rail from the front end of the moving direction, realizing the recycling of the first slider 505 and the second slider 506; at least three first sliders 505 are slidably engaged in the first slide rail 503, and at least three second sliders 506 are slidably engaged in the second slide rail 504, so that when the first sliders 505 and the second sliders 506 are circulated, at least two first sliders 505 and at least two second sliders 506 and their hook locks 507 can still be connected to the steel pipe 1, thereby maintaining the stable hooking of the steel pipe pile working platform.

[0118] To facilitate the application of force by the traction device 514, for steel pipe 1 that is closer to the steel pipe pile working platform, a transverse support rod 515 can be installed on the side away from the steel pipe pile working platform, and the traction device 514 is connected to the long rod; for steel pipe 1 that is farther away from the steel pipe pile working platform, the traction device 514 can be directly connected to the steel pipe 1.

[0119] The slider 14 can be inserted into or removed from the ends of the first slide rail 503 and the second slide rail 504 by striking it with a hammer. The gantry 508 is designed to avoid the steel pipe 1 and the bracket 4 while ensuring the connection rigidity between the two platform structures 501, preventing the platform structures 501 from becoming unstable. Scaffolding boards 509 are erected between the two platform structures 501. Both the first slide rail 503 and the second slide rail 504 include a sliding cavity 510 and a second opening 511 located at the upper part of the sliding cavity 510.

[0120] At least two steel pipe piles 3 are located within the passage 502. At least two hook-locking components 507 are hung on the steel pipe piles 3, wherein at least one is connected to a hook-locking component 507 as a first slider 505 and at least one is connected to a hook-locking component 507 as a second slider 506. By using the steel pipe pile working platform, a working platform can be flexibly and conveniently arranged around the steel pipe piles 3 at a relatively low cost, allowing workers to weld brackets 4 or perform other processing operations on the steel pipe piles 3. Furthermore, through the sliding engagement of the first slider 505 with the first slide rail 503, and the sliding engagement of the second slider 506 with the second slide rail 504, a working platform can be flexibly and conveniently formed between multiple consecutive steel pipe piles 3 by the movement of the steel pipe pile working platform, enabling processing operations on several steel pipe piles 3. At least three steel pipe piles 3 are arranged at straight-line intervals.

[0121] The hook lock 507 includes a second flexible rope 512 and a hook 513. One end of the flexible rope is connected to the slider 14, and the other end is connected to the hook 513. The hook 513 is engaged with the upper pipe opening of the steel pipe pile 3.

[0122] like Figures 27-32 As shown, in a preferred embodiment: the stone block 10 is lifted by a second lifting device, which includes a male-female pin connection assembly 6, a main lifting assembly, and an auxiliary lifting assembly. The male-female pin connection assembly 6 includes a first female head 63 and a second female head 64 that can simultaneously engage with the female head 62. The first female head 63, the second female head 64, and the female head 62 are connected by a pin 65. The main lifting assembly includes a first lifting device 601 and a bottom chain 602. The first lifting device 601 is connected to a first chain 611, a second chain 613, and a third chain 614. The lower end of the first chain 611 is connected to a hook 631, and the lower part of the second chain 613 is connected to a first branch chain 6. 16 and second branch chain 617, the lower end of the first branch chain 616 is connected to hook 2 632, the lower end of the second branch chain 617 is connected to hook 3 633, one end of the bottom chain 602 is connected to the female head 62, and the bottom of the third chain 614 is connected to the first male head 63; auxiliary lifting assembly, including a second lifting device 600, on which a first lifting rope 621 and a fourth chain 622 are connected, wherein: the length of the fourth chain 622 is longer than the length of the first lifting rope 621, the lower end of the fourth chain 622 is connected to the second male head 64, the bottom of the first lifting rope 621 is connected to one end of the pin 65; the end of the bottom chain 602 away from the female head 62 is connected to the first lifting device 601;

[0123] The lifting of the stone block 10 includes the following steps: S1.

Aligning the first male head 63, the second male head 64, and the female head 62, and inserting the pin 65 through the first male head 63, the second male head 64, and the female head 62, with one end of the pin 65 connected to the lifting rope 621 facing the stone block 10; S3. Forming an arc shape around the stone block 10 from below one side with the bottom chain 602 near the female head 62 and tightening it, and hooking both the first hook 631 and the second hook 632 with the bottom chain 602, so that the first chain 611, the second chain 613, and the third chain 614 are aligned around the stone block 10; Chain 611, chain 613, chain 614, and bottom chain 602 hold the stone 10 from one side; S4. The section of the fourth chain 622 near the second male head 64 is pulled taut around the stone 10 from the other side below, forming an arc shape, and hook 633 is hooked to the fourth chain 622, so that the second chain 613, chain 614, and fourth chain 622 hold the stone 10 from the other side. At this time, the portions of the first branch chain 616, the second branch chain 617, and the bottom chain 602 located between hook 632 and female head 62, and the fourth chain... S5. The portion of chain 622 located between hook 633 and second sub-head 64 forms a ring structure; S6. Lift the first lifting device 601 and the second lifting device 600, so that the first chain 611, the second chain 613, the third chain 614, the fourth chain 622 and the bottom chain 602 jointly lift the stone 10. At this time, the lifting rope 621 is in a slack state, and the portion of the fourth chain 622 located between hook 633 and the second lifting device 600 is also in a slack state; S6. After the stone 10 is lifted to the target position, continue to lower the first lifting device 601 a certain distance, so that the first chain 611 and the second chain 602 form a ring structure; S7. Both chain 613 and chain 614 are in a slack state; S8. Lift the second lifting device 600, so that the lifting rope 621 drives the pin 65 to disengage from the first male head 63, the second male head 64 and the female head 62, so that the bottom chain 602 is in a slack state, and the part of the fourth chain 622 located between the hook 633 and the second male head 64 is also in a slack state; S9. Lift the first lifting device 601 and the second lifting device 600, so that the first male head 63, the second male head 64 and the female head 62 are disengaged; S10. Continue to lift the first lifting device 601 and the second lifting device 600, and disengage the stone throwing device from the stone 10.

[0124] The main purpose of using a lifting rope 621 instead of a chain is to avoid interference between the chain links and the links of the first male head 63, the second male head 64, the female head 62, the bottom chain 602, or the fourth chain 622 when the pin 65 is pulled out of the female head 62, which would prevent the main lifting assembly or auxiliary lifting assembly from detaching from the stone.

[0125] The main lifting assembly and auxiliary lifting assembly lift the stone to the predetermined position. Then, the auxiliary lifting assembly is used to detach the main lifting assembly from the stone, thus achieving the purpose of separating the main lifting assembly from the stone. The entire process of separating the main lifting assembly from the stone does not require human intervention, avoiding safety risks to personnel during the lifting process.

[0126] The first sub-head 63, the second sub-head 64, and the female head 62 are connected by a pin 65. Hook 1 631 is hooked to the bottom chain 602, hook 2 632 is hooked to the bottom chain 602, and hook 3 633 is hooked to the fourth chain 622. Along the length of the bottom chain 602, hook 1 631 is located between the female head 62 and hook 2 632. When the first chain 611, the second chain 613, the third chain 614, the portion of the bottom chain 602 located between hook 2 632 and the female head 62, and the portion of the fourth chain 622 located between hook 3 633 and the second sub-head 64 are all tensioned, the first branch chain 616, the second branch chain 617, the portion of the bottom chain 602 located between hook 2 632 and the female head 62, and the portion of the fourth chain 622 located between hook 3 633 and the second sub-head 64 form a ring structure. The end of the bottom chain 602 away from the female head 62 is connected to the first lifting device 601.

[0127] The lifting rope 621 comprises a first flexible rope, a first chain segment, and a second flexible rope connected in sequence. The end of the second flexible rope furthest from the first chain segment is connected to a pin 65. The length of the second flexible rope is ≥0.5m. When lifting stones, the lifting rope 621 experiences a certain torsional force, posing a slight risk of the pin 65 rotating. In this case, by setting the lifting rope 621 to include the first flexible rope, the first chain segment, and the second flexible rope connected in sequence, the torsional force on the first flexible rope is released. At the same time, since the length of the second flexible rope is ≥0.5m, interference between the chain links of the first chain segment and the chain links of the first male head 63, the second male head 64, the female head 62, or the bottom chain 602 or the fourth chain 622 is avoided when the pin 65 is pulled out of the female head 62, preventing the main lifting assembly or auxiliary lifting assembly from detaching from the stone.

[0128] In a preferred embodiment, the first chain 611 comprises at least two strands, and the suspension rope 621 is preferably steel strand. A connector is provided between the suspension rope 621 and the pin 65. The connector includes a first structure 671 and a second structure 672 that are rotatably engaged. The second structure 672 is rotatably connected to the pin 65, and the first structure 671 is connected to the suspension rope 621. The relative rotation direction of the first structure 671 and the second structure 672 is perpendicular to the relative rotation direction of the second structure 672 and the pin 65. This configuration eliminates the torsional force present in the steel strand during use.

[0129] A preferred embodiment: The first structure 671 has a first rotating shaft 673 extending from the end away from the suspension rope 621. The second structure 672 is provided with a first through hole and a second rotating shaft 674. The first rotating shaft 673 is rotatably engaged with the first through hole, so that the second structure 672 can swing or rotate around the first rotating shaft 673. The rear end of the pin 65 is radially provided with a second through hole, which is rotatably engaged with the second rotating shaft 674, so that the pin 65 swings or rotates around the second rotating shaft 674.

[0130] In a preferred embodiment, one end of the pin 65 connected to the lifting rope 621 faces the stone 10. During the lifting process, since the fourth chain 622 and the bottom chain 602 are both in close contact with the stone 10 and are under tension, by having one end of the pin 65 connected to the lifting rope 621 facing the stone 10, it can be ensured that the pin 65 does not detach from the female head 62 during the lifting process. After the stone 10 is lifted to the target position, the second lifting device 600 is raised, causing the lifting rope 621 to rotate the pin 65 to a vertical position. Then, the second lifting device 600 continues to lift, thereby causing the pin 65 to smoothly disengage from the first female head 63, the second female head 64, and the female head 62.

[0131] like Figure 26 As shown, in a preferred embodiment, the corbel 4 includes a first side plate 420 and a second side plate 421 arranged opposite to each other. One end of the first side plate 420 is connected to a steel pipe 1, and the other end is connected to an end plate 422. One end of the second side plate 421 is connected to the steel pipe 1, and the other end is connected to the end plate 422. Both the first side plate 420 and the second side plate 421 are formed by cutting the remaining steel pipe section 11.

[0132] The concave surface of the first side plate 420 is opposite to the concave surface of the second side plate 421. The first side plate 420 and the second side plate 421 have upper end plates along the axial direction of the steel pipe 1, and the upper end plate 214 connects the first side plate 420 and the second side plate 421. The first side plate 420 and the second side plate 421 are welded to the steel pipe 1. Four brackets 4 are evenly distributed circumferentially on the steel pipe 1.

[0133] For driven piles that need to be cut at the top, the steel pipe 1 can be divided into the pile body 12 and the remaining steel pipe section 11. The remaining steel pipe section 11 can be located at the top of the pile body 12. When cutting the steel pipe 1, the remaining steel pipe section 11 needs to be cut and separated from the pile body 12. When making the bracket 4 on site, the remaining steel pipe section 11 can be cut and processed again to serve as at least part of the bracket 4. The bracket 4 is used to support the formwork system. The method of processing the bracket 4 using materials on site can effectively improve construction efficiency and reduce construction costs.

[0134] like Figure 33As shown, in a preferred embodiment, the beam grid includes at least two beam grid units 701 arranged sequentially. Each beam grid unit 701 includes three spaced longitudinal beam grooves 702 and four spaced transverse beam grooves 703. The longitudinal beam grooves 702 and transverse beam grooves 703 intersect at groove nodes 704. The longitudinal beam grooves 702 of adjacent beam grid units 701 are corresponding and connected. The three longitudinal beam grooves 702 are numbered C, D, and E sequentially, and the four transverse beam grooves 703 are numbered 1, 2, 3, and 4 sequentially. The groove nodes 704 between the longitudinal beam grooves 702 and transverse beam grooves 703 are numbered C1, C2, C3, C4, D1, D2, D3, D4, and E1, E2, E3, E4. The amount of concrete pumped by the first pump pipe per unit time is the same as the amount of concrete pumped by the second pump pipe.

[0135] The construction method includes the following steps: S1: The first pump pipe is set at node 704 of slot C1; the second pump pipe is set at node 704 of slot D1, and pouring begins simultaneously at nodes 704 of slot C1 and D1. At this time, the concrete at nodes 704 of slot C1 and D1 spreads outwards. S2: Concrete is conveyed sequentially at nodes 704 of slots C1, C2, D2, D3, C3, and C4 through the first pump pipe, and concrete is conveyed sequentially at nodes 704 of slots D1, E1, E2, E3, E4, and D4 through the second pump pipe. S3: The first pump pipe is moved to node 704 of slot C1 of the next beam grid unit 701, and the second pump pipe is moved to node 704 of slot D1 of the next beam grid unit 701. Then, S1-S2 are repeated until all the concrete conveying of the transverse and longitudinal beam slots 702 is completed, forming transverse and longitudinal beams.

[0136] The present application discloses a method for casting in-situ beam grids. Through the pumping method of the above-mentioned casting route similar to the concave-convex fit, the four spaced crossbeam grooves 703 have only two locations where the concrete material pumped by the first pump pipe and the concrete material pumped by the second pump pipe meet, which is equivalent to the pumping time of three groove nodes 704. In other locations, the concrete material pumped by the first pump pipe and the concrete material pumped by the second pump pipe meet, and the pumping time is less than that of three groove nodes 704. This effectively reduces the probability of cold joints.

[0137] Preferably, when the first pumping pipe pumps concrete at slot node 704, it moves towards the low-material area and returns; when the first pumping pipe pumps concrete at slot node 704, it moves towards the low-material area along a first direction and returns, the first direction being perpendicular to the direction in which the first pumping pipe reaches slot node 704; when the first pumping pipe pumps concrete towards slot node D2 704, it moves towards slot node D1 704 and returns; when the first pumping pipe pumps concrete towards slot node D3 704, it moves towards slot node E3 704 and returns; when the first pumping pipe pumps concrete towards slot node C3 704, it moves towards slot node C2 704 and returns; when the first pumping pipe pumps concrete towards slot node C4 705... When pumping concrete into slot node 704, the second pump pipe moves towards slot node 704 and returns; when pumping concrete into slot node 704, the second pump pipe moves towards slot node 704 and returns; when pumping concrete into slot node 704, the second pump pipe moves towards slot node 704 and returns; in two sequentially arranged beam grid units 701, when pumping concrete into slot node 704 in the later-cast beam grid unit 701, the second pump pipe moves towards slot node 704 in the earlier-cast beam grid unit 701 and returns; the width of the transverse beam slot 703 is equal to the width of the longitudinal beam slot 702, and the thickness of the transverse beam slot 703 is equal to the thickness of the longitudinal beam slot 702.

[0138] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
