[0072] Example 1

[0073] like Figure 1-33 As shown, this embodiment provides a wharf structure construction method as described in the present application, comprising the following steps: lifting a steel pipe 1 by a first lifting device and vertically arranging it, then driving the steel pipe 1 to a predetermined position, cutting off the excess portion of the upper portion of the steel pipe 1 to form a remaining steel pipe section 11, and lifting the remaining steel pipe section 11 away by the first lifting device;

[0074] A preferred method is: after the steel pipe 1 is injected to a predetermined position, the inside of the steel pipe 1 is processed, and the bottom of the inner side of the steel pipe 1 is inspected by a detection system;

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

[0076] A preferred method is to weld a corbel 4 on the outside of the steel pipe 1 through a steel pipe pile working platform, wherein at least part of the structure on the corbel 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 is: using a second lifting device to perform riprap construction around the steel pipe piles;

[0078] A preferred method is to set up a formwork system on the corbel 4 to form a beam grid groove, and place steel bars in the beam grid groove and cast them to form transverse and longitudinal beams.

[0079] like Figure 1-5 As shown, a preferred embodiment is as follows: at least three through holes are circumferentially opened at one end of the steel pipe 1, wherein the three through holes are a first through hole 111, a second through hole 112 and a third through hole 113, and all of them 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, the lower end of which 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, the lower end of which 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 lifting hook 108, the free end of the fourth lifting rope 106 is connected to a second lifting hook 109, and the free end of the fifth lifting rope 107 is connected to a third lifting hook 110;

[0081] Lifting the steel pipe 1 and vertically arranging it by 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 hanging the first hook 108, the second hook 109, and the third hook 110 to each other, and winding and fixing the first lifting rope 103 and the second lifting rope 104 around the other end of the steel pipe 1; A2: adjusting the steel pipe 1 from the horizontal direction to the vertical direction 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;

[0082] Lifting the remaining steel pipe section 11 by 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 the steel pipe 1, and reversely hanging the first hook 108 on the first through hole 111, the second hook 109 on the second through hole 112, and reversely hanging the third hook 110 on the third through hole 113; A4: lifting the second lifting rope assembly to adjust and remove the remaining steel pipe section 11.

[0083] During construction, the steel pipe 1 is changed from a horizontal state to a vertical state by first lifting the second lifting rope assembly and then lifting the first lifting rope assembly, or the lifting speed of the second lifting rope assembly is faster than that of 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 hung with each other in the steel pipe 1, and the first lifting rope 103 and the second lifting rope 104 are wrapped and fixed on the other end of the steel pipe 1, no lifting lugs are set on the outside of the steel pipe 1 throughout the whole process, thereby fundamentally avoiding the interference between the lifting lugs and the outer hoop equipment, and the problem that the lifting lugs are easily deformed by collision.

[0084] like Figure 5 As shown, in the later pile cutting process, the third lifting rope 105, the fourth lifting rope 106 and the fifth lifting rope 107 are lowered from the steel pipe 1, and the first lifting hook 108 is reversely hung at the first through hole 111, the second lifting hook 109 is reversely hung at the second through hole 112, and the third lifting hook 110 is reversely hung at the third through hole 113, so that the construction personnel can lift the part of the steel pipe 1 that has been cut by pulling out the hooks through the first through hole 111, the second through hole 112 and the third through hole 113, so that the steel pipe pile lifting device of the present application can not only be used for the lifting operation of the steel pipe 1, but also can take into account the lifting and moving operation of the remaining steel pipe section 11 cut during pile cutting, thereby making the second lifting rope assembly of the present application more universal.

[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 the lifting process; the first through hole 111 and the third through hole 113 are coaxially arranged; during the lifting process of the steel pipe 1, 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 can be reduced or avoided, thereby effectively extending the service life of the third lifting rope 105 and the fifth lifting rope 107.

[0086] like Figure 6-9 As shown, in another preferred embodiment, two through holes are provided on the steel pipe 1, which are respectively 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, the lower part of the first main rope 101 is connected to the first lifting rope 103 and the second lifting rope 104; the second lifting rope assembly includes a second main rope 102, the lower part of the second main rope 102 is connected to the third lifting rope 105 and the fourth lifting rope 106, 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 The first lifting ring 115 extends into the first through hole 111, and the second lifting ring 116 extends into the second through hole 112; the auxiliary lifting assembly 114 includes an auxiliary lifting rope 118, and the end of the auxiliary lifting rope 118 is connected to an auxiliary pin 119, and 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, and when the auxiliary lifting rope 118 applies tension to the auxiliary pin 119, the auxiliary pin 119 can detach from the first lifting ring 115, the second lifting ring 116 and the third lifting ring 117.

[0087] The construction method comprises the following steps: B1. inserting 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, with the third lifting ring 117 being arranged between the first lifting ring 115 and the second lifting ring 116; inserting the auxiliary pin 119 from the end of the steel pipe 1 into the steel pipe 1, and passing the auxiliary pin 119 through the first lifting ring 115, the third lifting ring 117 and the second lifting ring 116 in sequence; then tightening the third lifting rope 105 and the fourth lifting rope 106 so that one side of the auxiliary pin 119 is squeezed against the first lifting ring 115 and the second lifting ring 116, and the other side is squeezed against the third lifting ring 117; winding the first lifting rope 103 and the second lifting rope 104 around and fixing them to 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 lifted to a predetermined position and fixed; B3. The third lifting rope 105 and the fourth lifting rope 106 are in a relaxed 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 is separated from the first lifting ring 115, the second lifting ring 116 and the third lifting ring 117 until the auxiliary pin 119 lifts out the steel pipe 1; B5. Lift the second lifting rope assembly, and pull the first lifting ring 115 out of the first through hole 111, and the second lifting ring 116 out of the second through hole 112.

[0088] The present embodiment provides a steel pipe lifting construction method for steel pipe piles, which uses a first lifting rope assembly and a second lifting rope assembly to lift the steel pipe 1 to a predetermined position, and then uses the auxiliary pin 119 of the auxiliary lifting assembly 114 to disengage the auxiliary pin 119, the first lifting ring 115, the second lifting ring 116 and the third lifting ring 117, thereby achieving the purpose of automatically disengaging the second lifting rope assembly on the upper part of the steel pipe 1 from the steel pipe 1. Moreover, the entire process only requires setting the first through hole 111 and the second through hole 112 at one end of the steel pipe 1, and does not require setting a lifting ear on the outside of the steel pipe 1, thereby avoiding interference between the lifting ear and the outer hoop equipment, and 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 placed into the steel pipe 1 from the top, and 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 set between the first lifting ring 115 and the second lifting ring 116, and then the auxiliary pin 119 is sequentially passed through the first lifting ring 115, the third lifting ring 117 and the second lifting ring 116, and then the lifting is carried out.

[0090] Moreover, in step B1, when one side of the auxiliary pin 119 is squeezed against the first lifting ring 115 and the second lifting ring 116, and the other side of the auxiliary pin 119 is squeezed against the third lifting ring 117, it can effectively ensure that the auxiliary pin 119 does not separate 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] Auxiliary pin 119 is provided with a first inner recess 120 that cooperates with first lifting ring 115; a second inner recess 121 that cooperates with second lifting ring 116; and a third inner recess 122 that cooperates with third lifting ring 117. This further effectively ensures that auxiliary pin 119 does not separate from first lifting ring 115, second lifting ring 116, and third lifting ring 117 during the lifting process, thereby ensuring construction safety during the lifting process.

[0092] like Figure 9 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 the 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, and 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, and one side of the auxiliary pin 119 is squeezed against the first lifting ring 115 and the second lifting ring 116, and the other side of the auxiliary pin 119 is squeezed against the third lifting ring 117. In this case, at least one side of the shaft end structure 124 protrudes radially along the shaft body 123 of the auxiliary pin 119, which can further ensure that the auxiliary pin 119 does not separate 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 frustum structure, and the small end of the shaft end structure 124 is threadedly connected to the shaft body 123. The diameter of the small end of the shaft end structure 124 is adapted to the diameter of the shaft body 123. The shaft end structure 124 can be elastically deformed along the axial direction of the shaft body 123.

[0096] In a preferred manner, the data transmission cable 203 is partially wound in a forward direction on one side of the reel 206 , and partially wound in a reverse direction on the other side, so as to realize the retraction and extension of the data transmission cable 203 .

[0097] like Figure 11 As shown, camera 207 includes a lens 210, a cylindrical housing 211, and a camera data cable 212. Lens 210 is embedded in one end of cylindrical housing 211, and the other end of cylindrical housing 211 is connected to console 201 via camera data cable 212. Liquid level sensor 208 includes a probe 213, a liquid level sensor data cable 215, and a mounting plate 214. Probe 213 is embedded in the center of mounting plate 214 and connected to console 201 via liquid level sensor data cable 215. The edge of mounting plate 214 is suspended from cylindrical housing 211. Data transmission cable 203 is an armored cable that encases camera data cable 212 and liquid level sensor data cable 215.

[0098] The liquid level sensor 208 is connected to the camera 207 in a suspended manner via 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 one preferred embodiment, the data transmission cable 203 and the cable retraction device 204 together constitute a single-line winch. The data transmission cable 203 comprises 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 communication between the first cable and 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 Figure 12-14 As shown, a preferred embodiment includes: a steel bar rotating device; the steel cage 3 includes two main threaded steel bars 301 coaxially connected by a steel sleeve 303; the steel bar rotating device includes a driving device 401 and a clamping mechanism, the clamping mechanism includes a clamp head structure 402 and a clamp wall structure 403 connected thereto, the end of the clamp wall structure 403 away from the clamp head structure 402 is connected to a first rod 404, the connection between the first rod 404 and the clamp wall structure 403 forms a bend, 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 driving device 401, the clamp head structure 402 and the output shaft 411 are correspondingly arranged, the clamp head structure 402 clamps the main threaded steel bar 301 from one side of the main threaded steel bar 301, and the clamp head structure 402 is located at one end of the main threaded steel bar 301 away from the steel sleeve 303;

[0102] The longitudinal reinforcement is driven to rotate by the reinforcement rotating device so that adjacent main thread reinforcement bars 301 are connected through the reinforcement sleeves 303 .

[0103] During construction, the driving device 401 is installed at the end of the steel bar. Since the first rod 404 is bent at the connection with the clamp wall structure 403, the clamp head structure 402 can clamp the steel bar from the side of the steel bar. Compared with clamping along the axial direction of the steel bar, the clamping is more stable. In addition, 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 driving device 401. The torsional force of the output shaft 411 of the driving device 401 is transmitted to the first rod 404, the clamp wall structure 403 and the clamp head structure 402 in sequence through the universal joint 405. 2 is provided corresponding to the output shaft 411, so that the clamp head structure 402 can rotate around the rotation center of the output shaft 411, thereby driving the steel bar to rotate. When the steel bar rotates and its own weight produces a large rotation deformation, which will drive the end of the steel bar to jump, the universal joint 405 is capable of rotating in two directions, so that the clamp head structure 402 can also swing within a certain range along the radial direction of the output shaft 411, thereby effectively reducing the clamping force of the clamp head structure 402 used to overcome the steel bar from escaping the clamp head structure 402, thereby greatly reducing the probability of the steel bar end escaping 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 clamping space 307 and an opening 15 are formed between the first clamp head 412 and the second clamp head 413. The opening 15 is arranged radially along the output shaft 411. The first rod 404 and the clamp wall structure 403 together form an arch structure. The clamp head structure 402 is also provided with a limit ring 406 protruding from one side of the first rod 404. The limit ring 406 is coaxially arranged with the output shaft 411 and rotates together with the clamp head structure 402. During construction, the end of the steel bar is inserted into the limit ring 406 to reduce the amplitude of the steel bar end's vibration. It can also help reduce the clamping force of the clamp head structure 402 used to overcome the steel bar's escape from the clamp head structure 402, thereby greatly reducing the probability of the steel bar end escaping the clamp head structure 402 due to vibration.

[0105] The retaining ring 406 is connected to the first rod 404. Specifically, the retaining ring 406 is hingedly connected to the first rod 404, allowing the retaining ring 406 to swing toward or away from the output shaft 411.

[0107] The steel cage 3 includes a plurality of 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 steel pipe pile steel cage 3 .

[0108] By utilizing the semi-annular protrusions and grooves on the side of the threaded steel bar 308 itself, they are matched with the semi-annular protrusions and grooves on the side of the main threaded steel bar 301 of the steel cage 3 during use, so that the threaded steel bar 308 can limit the movement of the main threaded steel bar 301 relative to the first structure 304 and the second structure 305, thereby ensuring that when the first structure 304 and the second structure 305 clamp the main threaded steel bar 301, the main threaded steel bar 301 and the first structure 304 and the second structure 305 do not move relative to each other, so that the steel cage 3 does not move relative to the cage clamping device of the present application, so as to ensure 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 forming.

[0109] Threaded steel bars 308 are provided on both sides of the clamping space 307, and recessed portions 309 are provided on the first structure 304 and / or the second structure 305.

The steel cage 3 includes several main threaded steel bars 301 arranged along the length of the steel cage 3. At least one main threaded steel bar 301 extends through the clamping space 307. The side of the main threaded steel bar 301 and the threaded steel bar 308 are positioned in a concave and convex manner. The first structure 304 abuts the top of the steel pipe 1.

Match the first sub-head 63, the second sub-head 64 and the female head 62, and pass the pin 65 through the first sub-head 63, the second sub-head 64 and the female head 62, and the pin 65 is connected to the end of the lifting rope 1 621 toward the stone 10; S3. Form an arc shape around the stone 10 from the bottom side of the stone 10 near the female head 62 and tighten it, and hang the hook 1 631 and the hook 2 632 on the bottom chain 602 so that the first The first chain 611, the second chain 613, the third chain 614 and the bottom chain 602 hold the stone 10 from one side of the stone 10; S4. The fourth chain 622, which is close to the second sub-head 64, is formed into an arc shape around the stone 10 from the other side and tightened, and the third hook 633 is hung with the fourth chain 622, so that the second chain 613, the third chain 614 and the fourth chain 622 hold the stone 10 from the other side of the stone 10. At this time, the first sub-chain 616, the second sub-chain 617, the part of the bottom chain 602 located between the second hook 632 and the female head 62 and the fourth chain The portion of the rope 622 between the hook 3 633 and the second sub-head 64 forms a ring structure; S5. Lift the first sling 601 and the second sling 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 rope 1 621 is in a relaxed state, and the portion of the fourth chain 622 between the hook 3 633 and the second sling 600 is also in a relaxed state; S6. After the stone 10 is lifted to the target position, continue to lower the first sling 601 for a distance so that the first chain 611, the second chain 613, the third chain 614, the fourth chain 622 and the bottom chain 602 can lift the stone 10. 613 and the third chain 614 are both in a relaxed state; S7. Lift the second sling 600, so that the rope 1 621 drives the pin 65 to disengage from the first sub-head 63, the second sub-head 64 and the female head 62, so that the bottom chain 602 is in a relaxed state, and the part of the fourth chain 622 located between the hook 3 633 and the second sub-head 64 is also in a relaxed state; S8. Lift the first sling 601 and the second sling 600, so that the first sub-head 63, the second sub-head 64 and the female head 62 are disengaged; S9. Continue to lift the first sling 601 and the second sling 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 first sub-head 63, the second sub-head 64, the female head 62 or the chain links of the bottom chain 602 or the chain links of the fourth chain 622 when the pin 65 is pulled out of the female head 62, resulting in the main lifting component or the auxiliary lifting component being unable to separate from the stone.

[0125] The stone is lifted to the predetermined position by the main lifting assembly and the auxiliary lifting assembly, and then the auxiliary lifting assembly is used to separate the main lifting assembly from the stone, thereby 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 participation, 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 latch 65. Hook 1 631 is connected to the bottom chain 602, hook 2 632 is connected to the bottom chain 602, and hook 3 633 is connected 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 between hook 2 632 and the female head 62, and the portion of the fourth chain 622 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 between hook 2 632 and the female head 62, and the portion of the fourth chain 622 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 sling 601 .

[0127] The lifting rope 621 includes a first flexible rope, a first chain segment, and a second flexible rope connected in sequence. The end of the second flexible rope away from the first chain segment is connected to the latch 65, and the length of the second flexible rope is ≥0.5m. When lifting stones, the lifting rope 621 will have a certain torsional force during use, which will bring a small risk of rotating the latch 65. In this case, by configuring 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, when the latch 65 is pulled out of the female head 62, the chain links of the first chain segment are prevented from interfering with the chain links of the first sub-head 63, the second sub-head 64, the female head 62, or the bottom chain 602 or the fourth chain 622, resulting in the main lifting assembly or the auxiliary lifting assembly being unable to separate from the stone.

[0128] In a preferred embodiment, the first chain 611 comprises at least two pieces, and the first rope 621 is preferably a steel strand. A connector is connected between the first rope 621 and the latch 65. The connector includes a first structure 671 and a second structure 672 that are rotatably coupled. The second structure 672 is rotatably coupled to the latch 65. The first structure 671 is connected to the first rope 621, and 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 latch 65. This eliminates torsional forces on the steel strand during use.

[0129] A specific preferred method: a first rotating shaft 673 extends from the end of the first structure 671 away from the lifting rope 621, and a first through hole and a second rotating shaft 674 are provided on the second structure 672. The first rotating shaft 673 rotates with the first through hole so that the second structure 672 can swing or rotate around the first rotating shaft 673. A second through hole is radially provided at the rear end of the pin 65. The second through hole rotates 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, the end of the latch 65 connected to the lifting rope 1 621 is directed toward 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 in a tensioned state, the end of the latch 65 connected to the lifting rope 1 621 is directed toward the stone 10 to ensure that the latch 65 does not separate 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 lifted, so that the lifting rope 1 621 drives the latch 65 to rotate vertically, and then the second lifting device 600 continues to lift, thereby driving the latch 65 to smoothly separate from the first sub-head 63, the second sub-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 the steel pipe 1, and the other end is connected to the 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, and the first side plate 420 and the second side plate 421 are both formed by cutting the remaining steel pipe section 11.

[0132] The concave surface of the first side plate 420 is positioned opposite the concave surface of the second side plate 421. Upper end plates are provided at the axially upper ends of the first and second side plates 420, 421, with the upper end plate 214 connected between the first and second side plates 420, 421. The first and second side plates 420, 421 are welded to the steel pipe 1. Four corbels 4 are evenly distributed along the circumference of the steel pipe 1.

[0133] For the sunken pipe piles whose upper ends need to be cut, 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 upper end 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 the corbel 4 is made on site, the cut remaining steel pipe section 11 can be used to cut and process again as at least a part of the corbel 4. The corbel 4 is used to support the formwork system. The method of using construction site materials to process the corbel 4 can effectively improve construction efficiency and reduce construction costs.

[0134] like Figures 32-33As shown, in a preferred embodiment, the beam grid includes at least two beam grid units 701 arranged in sequence, and the beam grid unit 701 includes three longitudinal beam grooves 702 arranged at intervals and four transverse beam grooves 703 arranged at intervals. A groove node 704 intersects the longitudinal beam grooves 702 and the transverse beam grooves 703, and the longitudinal beam grooves 702 of adjacent beam grid units 701 correspond to and are connected. The three longitudinal beam grooves 702 are numbered C, D and E in sequence, and the four transverse beam grooves 703 are numbered 1, 2, 3, and 4 in sequence. The groove nodes 704 between the longitudinal beam grooves 702 and the transverse beam grooves 703 are numbered C1, C2, C3, C4, D1, D2, D3, D4, and E1, E2, E3, and E4. In unit time, the amount of concrete pumped by the first pumping pipe is the same as the amount of concrete pumped by the second pumping pipe.

[0135] The construction method includes the following steps: S1: setting a first pumping pipe at the C1 slot node 704; setting a second pumping pipe at the D1 slot node 704, and starting to pour concrete at the C1 slot node 704 and the D1 slot node 704 at the same time, at this time, the concrete at the C1 slot node 704 and the concrete at the D1 slot node 704 are both diffused toward the surroundings; S2: completing the concrete delivery at the C1, C2, D2, D3, C3, and C4 slot nodes 704 in sequence through the first pumping pipe, and synchronously completing the concrete delivery at the D1, E1, E2, E3, E4, and D4 slot nodes 704 in sequence through the second pumping pipe; S3: moving the first pumping pipe to the C1 slot node 704 of the next beam grid unit 701, and at the same time moving the second pumping pipe to the D1 slot node 704 of the next beam grid unit 701; then repeating S1-S2 until the concrete delivery of all 10 sections of the transverse and longitudinal beam slots 702 is completed to form transverse and longitudinal beams.

[0136] A method for casting a cast-in-place beam grid in the present application uses a pumping method similar to the above-mentioned concave-convex matching casting route, so that there are only two positions of the four spaced-apart beam grooves 703, where the pumping time of the concrete material pumped out by the first pumping pipe and the concrete material pumped out by the second pumping pipe is the same as that of the three groove nodes 704, and the pumping time of the concrete material pumped out by the first pumping pipe and the concrete material pumped out by the second pumping pipe at the rest of the positions is less than the pumping time of the three groove nodes 704, thereby effectively reducing the probability of cold joints.

[0137] Preferably, the first pumping pipe moves toward the less-material area and returns when pumping concrete at the slot node 704; the first pumping pipe moves along the first direction of the less-material area and returns when pumping concrete at the slot node 704, and the first direction is perpendicular to the direction when the first pumping pipe reaches the slot node 704; the first pumping pipe moves toward the D1 slot node 704 and returns when pumping concrete to the D2 slot node 704; the first pumping pipe moves toward the E3 slot node 704 and returns when pumping concrete to the D3 slot node 704; the first pumping pipe moves toward the C2 slot node 704 and returns when pumping concrete to the C3 slot node 704; the first pumping pipe moves toward the C4 slot node 704. When the slot node 704 pumps concrete, it moves toward the D4 slot node 704 and returns; when the second pumping pipe pumps concrete to the E2 slot node 704, it moves toward the D2 slot node 704 and returns; when the second pumping pipe pumps concrete to the D4 slot node 704, it moves toward the D3 slot node 704 and returns; in the two sequentially arranged beam grid units 701, when the second pumping pipe pumps concrete to the E1 slot node 704 in the later-cast beam grid unit 701, it moves toward the E4 slot node 704 in the first-cast beam grid unit 701 and returns; the width of the crossbeam slot 703 is equal to the width of the longitudinal beam slot 702, and the thickness of the crossbeam slot 703 is equal to the thickness of the longitudinal beam slot 702.

[0138] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
