During the pouring process, the shaping tool structure of the shaft pile head is an integral ring structure. It is difficult to disassemble the shaft pile head after shaping. At the same time, after the steel cage is installed, the humidity of the concrete is too high to form a stable support for the steel cage. Additional auxiliary devices are required to shape the steel cage, which is not only time-consuming, but also consumes a lot of manpower and material resources. At the same time, it is easy to increase the difficulty of quality control due to the large number of construction links, affecting the quality and safety of the project.

Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features; in the description of this application, unless otherwise specified, "plurality" means two or more.

[0024] Figure 1-Figure 4 A one-step forming device for a well pile head provided in an embodiment of the present application comprises: a forming seat 1 and a sealing cover 2, wherein the forming seat 1 comprises a first side ring 11 and a second side ring 12 which are hingedly connected at one end by a hinge shaft 14, and a handle 13 is arranged on each of the first side ring 11 and the second side ring 12, and the first side ring 11 and the second side ring 12 on the side close to the hinge shaft 14 are connected by a telescopic inner ring 15, and a fixed inner ring 15 is fixed in the first side ring 11 away from the hinge shaft 14. A positioning ring 16 is provided, and the positioning ring 16 can be inserted into the second side ring 12, and a limiting shaft 17 is rotatably provided at the other end of the second side ring 12, and the limiting shaft 17 can be engaged with the first side ring 11, and a cover 2 can be fastened on the handle 13, and the cover 2 includes a cover plate 21 fixed to the first side ring 11 and the second side ring 12, a casting hole 22 is opened through the axis center of the cover plate 21, and a plurality of embedded shafts 23 are evenly arranged on the upper circumference of the cover plate 21.

[0025] On the basis of the above technical scheme, the required main reinforcement is first inserted into the embedded shaft 23, and a plurality of stirrups are fixed on the main reinforcement on the side away from the embedded shaft 23 according to the height of the pile head to form a steel cage. The operator places the first side ring 11 and the second side ring 12 at the fixed installation position of the pile head, locks the first side ring 11 and the second side ring 12 through the limit shaft 17, and then puts the steel cage into the locked forming seat 1, and rotates to a suitable position, and then fixes the forming seat 1 and the cover 2, controls the concrete to be injected from the pouring hole 22 into the cavity formed by the forming seat 1 and the cover 2, and after the concrete solidifies, opens the forming seat 1 and the cover 2, takes out the cover 2 from the upper end of the main reinforcement, and then takes out the limit shaft 17 from the first side ring 11, opens the first side ring 11 and the second side ring 12, and completes the one-time forming of the pile head.

[0026] The above technical solution is adopted, through the first side ring 11 and the second side ring 12 that can be locked and opened, which is conducive to the subsequent shaping of the well pile head and the disassembly of the forming seat 1. At the same time, continuous operation from steel cage installation to concrete pouring is realized, which greatly shortens the construction period, reduces the time loss between multiple processes in traditional construction, and improves the overall construction efficiency.

[0027] In one possible implementation, a handle 171 is fixedly provided on the limiting shaft 17 away from the second side ring 12, and the limiting shaft 17 can be rotated by the handle 171 to open or lock the first side ring 11 and the second side ring 12. When the first side ring 11 and the second side ring 12 are opened, it is convenient to quickly disassemble the cover 2 and the molding seat 1; when the first side ring 11 and the second side ring 12 are locked, it is convenient to form a casting space after the cover 2 and the molding seat 1 are fixed.

[0028] In a possible implementation, barbs 131 are fixedly provided on both sides of the handle 13 .

[0029] In a possible implementation, the bottom end of the cover plate 21 is a horizontal circular structure, which is conducive to the molding of the top of the well pile head.

[0030] In one possible implementation, four buckles 24 are fixedly provided on the cover plate 21, and the buckles 24 are provided corresponding to the barbs 131. During the concrete pouring process, the buckles 24 and the barbs 131 are engaged with each other, so that the cover 2 and the forming seat 1 are fixed to form a pouring space; after the concrete pouring is completed, the buckles 24 and the barbs 131 are opened to facilitate the quick disassembly of the cover 2 and the forming seat 1.

[0031] In a possible implementation, the embedded shaft 23 includes a vertical shaft 231 fixed to the cover plate 21 , an axial through hole 232 is defined in the vertical shaft 231 , and the axial through hole 232 is disposed through the cover plate 21 .

[0032] Based on the above technical solution, the main reinforcement is first inserted into the vertical shaft 231 through the axial through hole 232, and a plurality of stirrups are fixed on the main reinforcement on the side away from the vertical shaft 231 according to the height of the pile head to form a steel cage. During the pouring process, the vertical shaft 231 can provide a stable support for the steel cage, and at the same time enable continuous operations from the installation of the steel cage to the pouring of concrete.

[0033] In a possible implementation, the upper end of the axial through hole 232 is configured as an inverted trumpet-shaped structure.

[0034] By adopting the above technical solution, the inverted trumpet-shaped axial through hole 232 makes it easier to guide the main reinforcement into the predetermined position, especially in the case of limited space or poor vision, which can greatly reduce the obstruction when the main reinforcement is inserted into the vertical shaft 231, thereby improving construction efficiency.

[0035] Working principle:

[0036] S1. First, insert the required main reinforcement into the vertical axis 231, and fix a plurality of stirrups on the main reinforcement on the side away from the vertical axis 231 according to the height of the pile head to form a steel cage;

[0037] S2, placing the first side ring 11 and the second side ring 12 at the fixed installation position of the well pile head, and locking the first side ring 11 and the second side ring 12 through the limit shaft 17;

[0038] S3, put the steel cage into the locked forming seat 1, rotate it to a suitable position, and then lock the lock 24 with the barb 131;

[0039] S4, injecting concrete from the pouring hole 22 into the cavity formed by the forming seat 1 and the cover 2;

[0040] S5. After the concrete solidifies, the buckle 24 and the barb 131 are opened, the cover 2 is taken out from the upper end of the main reinforcement, and the limit shaft 17 is taken out from the first side ring 11 through the handle 171, and the first side ring 11 and the second side ring 12 are opened to complete the one-step forming of the pile head.
