[0031] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0032] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0034] In the description of this embodiment, the terms "upper", "lower", "left", "right", etc., and the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of description and simplified operation, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0035] Based on what has been mentioned above, currently the pile tip and the pile body are mostly connected by welding. However, during the construction process, the force on the pile tip suddenly increases when it enters the hard layer from the soft soil layer, which can easily lead to cracks in the weld between the pile tip and the pile body, causing the pile tip to tilt or fall off and unable to ensure normal guidance of the pile body, which can easily cause the pile body to tilt.

[0036] To solve the above problems, please refer to Figures 1 to 3 This embodiment provides a pile tip, which is used to be installed at the end of a pile body 100. The pile tip includes a main body 1, a sliding member 2, a sliding groove 3, a limiting assembly 4 and a reinforcement body 5.

[0037] Specifically, the main body 1 is a cone, and the main body 1 gradually becomes larger from top to bottom. The sliding member 2 is integrally formed at the upper end of the main body 1, and a sliding groove 3 is horizontally opened at the end of the pile body 100, and at least one end of the sliding groove 3 is open. This embodiment does not make specific requirements and restrictions on the size and shape of the sliding groove 3. Preferably, the sliding groove 3 is preferably a T-shaped groove, and the sliding member 2 is correspondingly set as a slider with a T-shaped cross section, which will not be described in detail.

[0038] The sliding member 2 is slidably matched with the slide groove 3, that is, the sliding member 2 can slide along the slide groove 3 and has a fixed position. The fixed position is the position where the sliding member 2 is located in the slide groove 3 when the pile tip and the pile body 100 are correctly matched. The reinforcement body 5 is arranged in a conical shape with a larger upper part and a smaller lower part, and the reinforcement body 5 is arranged at the center of the lower end of the main body 1.

[0039] It can be understood that, during the process of installing the pile tip, the sliding member 2 is slid along the sliding groove 3 to a preset position, so that the pile body 100 can be assembled into one piece, which has a simple structure and is easy to operate.

[0040] It can also be understood that the assembly structure formed by the cooperation between the sliding member 2 and the slide groove 3 can effectively reduce the situation where the pile tip is skewed or dropped due to force, thereby ensuring the normal guidance of the pile body 100 during the construction process, and further reducing the tilting of the pile body 100.

[0041] In addition, the limiting assembly 4 is used to limit the sliding member 2 to a fixed position. The limiting assembly 4 includes a connecting hole 41, a blind hole 42 and a connecting member 43. The connecting hole 41 is opened through the main body 1. The blind hole 42 is opened at the end of the pile body 100, and the blind hole 42 is correspondingly connected to the connecting hole 41. The connecting member 43 is embedded in the connecting hole 41 and partially extends into the blind hole 42.

[0042] It can be understood that, by embedding the connecting member 43 in the connecting hole 41 and partially extending into the blind hole 42, it can be ensured that the pile body 100 and the pile tip do not move relative to each other in the horizontal direction, that is, the sliding member 2 can be restricted to a fixed position, thereby ensuring the reliability of the connection between the pile tip and the pile body 100.

[0043] In order to further improve the connection reliability between the pile tip and the pile body 100, a plurality of connection holes 41 are provided, and the plurality of connection holes 41 are evenly distributed around the main body 1. In this embodiment, six connection holes 41 are provided, and correspondingly, the number of blind holes 42 and connecting members 43 are provided corresponding to the number of connection holes 41. Such a configuration can also make the force consistency around the main body 1 better.

[0044] Furthermore, the cross section of the connecting member 43 is arranged in a square shape, and the connecting hole 41 and the blind hole 42 are both shaped like the connecting member 43. Such an arrangement makes it easier to align the transfer hole 45 on the connecting member 43 with the through hole 44 for communication.

[0045] In order to improve the convenience of pile tip assembly, the reinforcement body 5 is screwed to the main body 1. It should be noted that the material strength of the reinforcement body 5 needs to be greater than the material strength of the main body 1. In this embodiment, the main body 1 is made of cast iron, and the reinforcement body 5 is made of cemented carbide GT35, which will not be described in detail.

[0046] Preferably, the limiting assembly 4 further includes a through hole 44, a transfer hole 45 and a reinforcement member (not shown in the figure). The through hole 44 is opened on the pile body 100 along the horizontal direction, and the through hole 44 can be connected to at least two blind holes 42. The transfer hole 45 is opened on the connecting member 43 along the horizontal direction, and the transfer hole 45 can be connected to the through hole 44. The reinforcement member is slidably arranged in the through hole 44 and passes through the transfer hole 45 in at least two blind holes 42.

[0047] It can be understood that, by sliding the reinforcing member through the through hole 44 and passing through the transfer holes 45 in at least two blind holes 42, in other words, by simultaneously passing the reinforcing member through the transfer holes 45 on the two connecting members 43 in the horizontal direction, the two connecting members 43 can be prevented from escaping from the blind holes 42, thereby effectively ensuring the connection strength between the main body 1 and the pile body 100.

[0048] In this embodiment, a square pile is further provided, and the square pile includes the above-mentioned pile tip and a pile body 100. It can be understood that the square pile including the above-mentioned pile tip is not easy to tilt during the construction process.

[0049] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
