[0036] The formwork material is concrete above C40. When the strength is insufficient, steel bars can be added. The shape of the formwork is an L shape with a groove at the tail. The depth of the groove is related to the size of the foundation pile cap. The conventional depth is L / 3, where L is the length of the foundation pile cap.

Four formworks form a complete formwork system. The first to third formworks can be directly inserted into the groove, and the fourth formwork is embedded into the groove from top to bottom to achieve stability through the engagement of the tail groove. This formwork is convenient to install and does not require additional reinforcement measures such as inclined struts. Moreover, after the pouring of the pile cap is completed, there is no need to remove the formwork, which can directly serve as a part of the foundation pile cap, facilitating the next step of earth backfilling construction and greatly improving the construction efficiency.

[0037] As Figure 3 shown, the 3D printing component includes a first fixing block 301. A first electric push rod 302 is installed on one side wall of the first fixing block 301.

Subsequently, start the third electric push rod 309 to drive the 3D printing structure 310 to descend, improving the spatial limitation effect of printing. Subsequently, during the horizontal printing process, start the first electric push rod 302 to push the second fixing block 303 to move. While the second fixing block 303 moves, it drives the 3D printing structure 310 to move, expanding the working range of printing. And in the non-working state, the first motor 304 can be started to drive the 3D printing structure 310 to rotate, expanding the detection range of the printing structure and improving the stable effect of the printing structure during operation.

[0039] As Figure 4As shown in the figure, the moving component 4 includes a second electric slide 401. The bottom of the second electric slide 401 is mounted on the top of the printing base plate 1.

Two groups of seventh electric push rods 412 are symmetrically mounted on both side walls of the ninth fixing block 411. A connecting plate 413 is mounted on the output end of each group of the seventh electric push rods 412.

[0040] Before the manufacturing structure works, first start the second electric slide 401 to drive the two connecting plates 413 to slide to the specified position. Subsequently, start the fourth electric push rod 403 to push the two connecting plates 413 into the grooves of the printing template that need to be printed. During the subsequent printing process, start the fifth electric push rod 405 for height adjustment. And when preventing the problem of incomplete subsequent printing, the seventh electric push rod 412 can be started to perform auxiliary adjustment work for the horizontal position. And to expand the subsequent printing space, the second motor 406 can be started to drive the seventh fixing block 407 to rotate, so that the manufacturing component 5 rotates, expanding the manufacturing space and improving the flexible effect of structural adjustment at the same time.

[0041] As Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9As shown, the manufacturing component 5 includes a first mounting plate 501. The top of each group of the first mounting plates 501 is mounted on the bottom of the connecting plate 413. A group of second mounting plates 502 is arranged directly below each group of the first mounting plates 501. Two movable collar 503 are symmetrically mounted on the bottom of each group of the first mounting plates 501. A rotating rod 504 is rotatably connected between the two movable collars 503. A fixed collar 505 is sleeved on the outer wall of each group of the rotating rods 504. The outer wall of each group of the fixed collars 505 is mounted on the top of the second mounting plate 502. A fourth motor 506 is mounted on the bottom of each group of the first mounting plates 501. The output end of each group of the fourth motors 506 is drivingly connected to the rotating rod 504. A third mounting plate 507 is mounted on the bottom of each group of the second mounting plates 502. A first hydraulic push rod 508 is mounted on one side wall of each group of the third mounting plates 507. A fourth mounting plate 509 is mounted on the output end of each group of the first hydraulic push rods 508. A sliding cavity 511 is formed on one side wall of each group of the fourth mounting plates 509. Two threaded rods 510 are rotatably connected in each group of the sliding cavities 511. A partition plate is connected between the two threaded rods 510. The threading directions of the two threaded rods 510 are opposite and their central axes are on the same straight line. A sliding block 512 is threadedly connected to each group of the threaded rods 510. Each sliding block 512 is slidably connected in the sliding cavity 511. A first grinding plate 513 is mounted on one side wall of each group of the sliding blocks 512. A fifth motor 514 is mounted on the inner wall of each group of the fourth mounting plates 509. The output end of each group of the fifth motors 514 is drivingly connected to one of the threaded rods 510. An abrasion-resistant plate 515 is mounted on one side wall of each group of the first grinding plates 513, and a third electric sliding table 516 is mounted on the top. The output end of each group of the third electric sliding tables 516 is drivingly connected to a second hydraulic push rod 517. A positioning block 518 is mounted on the output end of each group of the second hydraulic push rods 517. A sliding column 519 is mounted on the top of each group of the first grinding plates 513. A sliding plate 520 is slidably connected to the top of the two sliding columns 519. A fifth mounting plate 521 is mounted on the top of each group of the sliding plates 520. One end of two compression springs 522 is symmetrically mounted on one side wall of each group of the fifth mounting plates 521. A second grinding plate 523 is mounted on the other end of the compression spring 522. A second electromagnetic block 526 is mounted on one side wall of each group of the second grinding plates 523. A third hydraulic push rod 524 is mounted on one side wall of each group of the fifth mounting plates 521. A first electromagnetic block 525 is mounted on the output end of each group of the third hydraulic push rods 524. The first electromagnetic block 525 is magnetically connected to the second electromagnetic block 526.On the top of each group of the fifth mounting plates 521, a group of distance sensors 527 are installed.

[0042] During the initial printing process of the 3D printing structure, the third electric sliding table 516 is started to drive the positioning block 518 to move to the edge of the printing point. When the printing range deviates, the concrete raw material will be printed on the positioning block 518. During normal printing work, the second hydraulic push rod 517 can be started for height climbing follow-up, and the fifth motor 514 is started to drive the threaded rod 510 to rotate. While the threaded rod 510 rotates, it drives the sliding block 512 to slide in the sliding cavity 511. While the sliding block 512 slides, it drives the two first grinding plates 513 to move. While the first grinding plates 513 move, they drive the two positioning blocks 518 to move and follow according to the printing points of the 3D printing structure 310. And when the printing structure prints the template to the specified height, while the fifth motor 514 drives the first grinding plates 513 to move, it can drive the grinding plates to grind the surface of the concrete template groove, improving the printing range monitoring effect and the grinding effect of the concrete template at the same time.

[0043] After the template is printed in place, the fifth electric push rod 405 is started to drive the height of the first mounting plate 501 to be higher than the template. Then the fourth electric push rod 403 is started to push the first mounting plate 501 to be directly above the template. Then the fourth motor 506 is started to drive the rotating rod 504 to rotate. While the rotating rod 504 rotates, it drives the second mounting plate 502 on the fixed collar 505 to rotate, so that the second grinding plate 523 is located directly above the template. Then the third hydraulic push rod 524 is started to push the first electromagnetic block 525 to be magnetically connected to the second electromagnetic block 526. Then the third hydraulic push rod 524 is started to drive the second grinding plate 523 to move towards the fifth mounting plate 521. During its movement, the compression spring 522 is compressed. Then the first hydraulic push rod 508 is started to drive the second grinding plate 523 to descend towards the template. The fifth motor 514 is started to drive the two first grinding plates 513 to fit on the outer wall of the template. Then the magnetic connection state between the first electromagnetic block 525 and the second electromagnetic block 526 is disengaged, so that after the compression spring 522 senses the disappearance of the pressure, it drives the second grinding plate 523 to fit on the top of the template. Then the seventh electric push rod 412 is started to push forward, and the surface of the template is ground during its pushing process. And when there are depressions and protrusions on the top of the template, it will drive the compression spring 522 to rebound, and the distance sensor 527 is used for auxiliary monitoring, improving the finished product precision effect of the template and the manufacturing effect of the template at the same time.

[0044] The template is in an L shape with a groove at the tail. The depth of the groove is related to the size of the foundation pile cap. The conventional depth is L / 3, where L is the length of the foundation pile cap. The template size can be freely adjusted according to the situation of the foundation pile cap. This template is used for the casting construction of the foundation pile cap. Four templates form a complete template system. The first to the third templates can be directly inserted into the groove, and the fourth template is inserted into the groove from top to bottom. The tail groove is used for biting to achieve the purpose of firmness. The template is convenient to install and does not require additional bracing and other reinforcement measures. After the casting of the pile cap is completed, there is no need to remove the formwork, which can be directly used as a part of the foundation pile cap, facilitating the next step of earth backfilling construction and greatly improving the construction efficiency.

[0045] Start the fifth motor 514 to drive two groups of first grinding plates 513 to fit on the outer wall of the template. Then, disconnect the magnetic connection state between the first electromagnetic block 525 and the second electromagnetic block 526, so that after the compression spring 522 senses the disappearance of the pressure, it drives the second grinding plate 523 to fit on the top of the template. Then, start the seventh electric push rod 412 to push forward, and during the pushing process, grind the surface of the template. When there are depressions and protrusions on the top of the template, it will drive the compression spring 522 to rebound, and the distance sensor 527 is used for auxiliary monitoring, improving the precision effect of the template finished product while improving the manufacturing effect of the template.

[0046] Start the third electric slide 516 to drive the positioning block 518 to move to the edge of the printing point. When the printing range deviates, the concrete raw material will be printed on the positioning block 518. During normal printing work, the second hydraulic push rod 517 can be started for height climbing follow-up, and the fifth motor 514 can be started to drive two groups of first grinding plates 513 to move. While the first grinding plate 513 moves, it drives two groups of positioning blocks 518 to move following the printing points of the 3D printing structure 310. When the printing structure prints the template to the specified height, while the fifth motor 514 drives the first grinding plate 513 to move, it can drive the grinding plate to grind the surface of the groove of the concrete template, improving the monitoring effect of the printing range while improving the grinding effect of the concrete template.

[0047] Start the first electric slide 308 to drive the 3D printing structure 310 to move to the specified position. Then, start the third electric push rod 309 to drive the 3D printing structure 310 to descend, improving the spatial limitation effect of printing. Then, during horizontal printing, start the first electric push rod 302 to push the second fixing block 303 to move. While the second fixing block 303 moves, it drives the 3D printing structure 310 to move, expanding the working range of printing. And in the non-working state, the first motor 304 can be started to drive the 3D printing structure 310 to rotate, expanding the detection range of the printing structure and improving the stability effect of the printing structure work.

[0048] Start the second electric slide table 401 to drive the two sets of connecting plates 413 to slide to the designated position. Subsequently, start the fourth electric push rod 403 to push the two sets of connecting plates 413 into the groove where the printing template is required. During the subsequent printing process, start the fifth electric push rod 405 for height adjustment. And when preventing the problem of incomplete printing in the subsequent process, the seventh electric push rod 412 can be started to perform the auxiliary adjustment work of the horizontal position. And to expand the subsequent printing space, the second motor 406 can be started to drive the seventh fixing block 407 to rotate, so that the manufacturing assembly 5 rotates, expanding the manufacturing space and improving the flexible effect of structural adjustment at the same time.
