Description

Technical Field

[0001] The invention relates to the technical field of spiral anchor foundations, in particular to a recyclable prestressed combined spiral anchor foundation. Background Art

[0002] The spiral anchor foundation is a new type of all-steel foundation. It is constructed by welding several spiral anchor plates on the steel pipe and screwing them into the ground like screws during construction. It has good pull-out, compression and overturning resistance. Compared with conventional tower foundations, the spiral anchor has the advantages of simple structure, convenient construction, high degree of mechanization and less impact on water and soil resources. Mechanized construction can significantly reduce labor and shorten construction period, with significant economic benefits.

[0003] Prestressing: Prestressing is the compressive stress pre-applied to the structure during construction in order to improve the service performance of the structure. The pre-applied compressive stress during the service life of the structure can fully or partially offset the tensile stress caused by the load and avoid structural damage. It is often used in concrete structures. Prestressed concrete structures are structures that are pre-applied with pressure before the structure is subjected to loads, so that the internal force of the concrete in the tensile zone under the action of external loads produces compressive stress, which is used to offset or reduce the tensile stress caused by the external load, so that the structure will not produce cracks or crack relatively late under normal use.

[0004] The existing spiral anchor foundation is installed in a spiral manner during use, so it can be disassembled by reverse rotation after use. However, the spiral anchor is located underground for a long time and is easily affected by geology.

As the fixing member 708 and the fixing rod 707 rise, the lifting plate frame 705 drives the lifting roller 703 to move upward. Since the lifting roller 703 contacts the arc connecting rod 706, the arc connecting rod 706 can be driven to rotate on the installation shaft rod 709, and then the stabilizing plate 701 is driven to rise until the stabilizing plate 701 contacts the outer wall of the anchor rod 2, completing the fixed support, thereby ensuring the guiding stability of the subsequent anchor rod 2 during anchoring;

[0038] In a specific application scenario, the guiding and stabilizing module 7 is suitable for the guiding link of the spiral anchor foundation, that is, the radial cover 1 can perform preliminary guidance on the spiral anchor foundation when in use, and at the same time, the guiding and stabilizing module 7 can cooperate with the radial cover 1 to perform further limiting guidance on the spiral anchor foundation when in use. During installation, the guiding and stabilizing module 7 can clamp the anchor end rod 2 through the arc rod 704 and the stabilizing plate 701, thereby controlling the distance between the outer wall of the anchor end rod 2 and the inner wall of the radial cover 1 during use to avoid changes in the distance, thereby avoiding the spiral anchor foundation from being offset during installation and use, so as to ensure the guiding stability of the spiral anchor foundation during installation and increase the use effect of the device.

[0039] Working principle: During installation, when the anchor rod 4 is moved to the installation position, the drive motor 501 is started, and the drive rod 504 is driven to rotate by the drive motor 501, and then the drive gear ring 514 is driven to rotate by the drive rod 504. Since the drive gear ring 514 is meshed with the driven gear 519, the drive motor 501 can drive the driven gear 519 to rotate, and then the driven gear 519 drives the screw rod 516 to rotate. The rotation of the screw rod 516 can make the mounting seat 513 moves, and then the mounting seat 513 drives the connecting plate 512 to push the prestressed plate 502, so that the prestressed plate 502 is bent. At this time, the connecting ring 509 can drive the prestressed sub-plate 508 to bend, and then prestress is applied to the prestressed plate 502 and the prestressed sub-plate 508. At the same time, when the prestressed plate 502 and the prestressed sub-plate 508 are bent, the movable block seat 510 can drive the movable ring frame 507 to move, so that the elastic corrugated ring 503 is folded, and the prestress setting is completed;

[0040] When in use, the anchor rod 4 is docked with the anchor end rod 2, the driving rod 504 and the driving connecting rod 8, and the stepping motor 608 is started at this time, and the winding wheel 609 is driven by the stepping motor 608 to rotate, and the winding wheel 609 can pull the connecting cable 610, and then the cable wheel 603 is driven to rotate through the connecting cable 610, so that the torsion spring 611 is deformed, and then the installation rod 612 is driven to rotate. Since the rotation of the installation rod 612 can drive the gear 1 613 and the gear 2 614 to rotate, the gear 1 613 and the gear 2 614 drive the toothed plate frame 606 and The toothed plate 616 moves, thereby causing the guide frame 617 and the docking member 602 to move. At this time, the two guide frames 617 contact to form a circular ring, and drive the limiting guide wheel 615 and the interface member 604 to move. Since the guide frames 617 contact to form a circular ring, the limiting guide wheel 615 can rotate inside it, so as to drive the connecting rod 8 to operate after docking. At this time, the interface member 604 and the docking member 602 cooperate with the connecting rod 1 605 and the connecting rod 2 607 to drive multiple interface members 604 and multiple docking members 602 to enter the connecting rod interface 10 and the anchor rod interface 11 to complete the docking.

[0041] When the anchor end rod 2 is installed, the radial cover 1 is arranged on its outside through the threaded rod 15, the threaded seat 14 and the nut 12. At this time, the electric telescopic rod 711 is started, and the electric telescopic rod 711 can drive the arc connecting rod 706 to rise, and then the arc connecting rod 706 drives the fixing member 708 and the fixing rod 707 to rise. As the fixing member 708 and the fixing rod 707 rise, the lifting plate frame 705 drives the lifting roller 703 to move upward. Since the lifting roller 703 contacts the arc connecting rod 706, it can drive the arc connecting rod 706 to rotate on the installation shaft rod 709, and then drive the stabilizing plate 701 to rise until the stabilizing plate 701 contacts the outer wall of the anchor end rod 2, completing the fixed support, thereby ensuring the guiding stability of the subsequent anchor end rod 2 during anchoring.
