[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1

[0025] like Figure 1 - Figure 4 As shown, the utility model provides a technical solution: a high-strength pipe pile foundation pit support, comprising: a supporting mechanism 1, a fixing mechanism 2 is arranged on one side of the supporting mechanism 1, the supporting mechanism 1 comprises a transverse plate 16, an empty pipe 17 is arranged inside the transverse plate 16, the inside of the transverse plate 16 is penetrated and fixed with the outside of the empty pipe 17, a locking block 18 is arranged on the inner wall of the empty pipe 17, the inner wall of the empty pipe 17 is penetrated and connected with one end of the locking block 18, a limiting block 111 is arranged inside the locking block 18, the inside of the locking block 18 is in contact with the outside of the limiting block 111, one end of the limiting block 111 is fixedly connected with the inner wall of the empty pipe 17, an extrusion rod 19 is arranged at one end of the locking block 18, one end of the locking block 18 is in sliding contact with the outside of one end of the extrusion rod 19, a fixing piece 110 is arranged inside one end of the empty pipe 17, and the inside of one end of the empty pipe 17 is in contact with the fixing piece 110 One end of the fixed piece 110 is connected with the outer thread, and one end of the fixed piece 110 is connected with the inner thread of the extrusion rod 19. A movable arm 15 is provided at the bottom of the cross plate 16, and the bottom of the cross plate 16 is fixedly connected to the top of the movable arm 15. The bottom end of the movable arm 15 is movably connected to the inner side of one end of the fixed plate 14. The interior of the fixed plate 14 is penetrated and fixed with the outer side of one end of the connecting rod 13. A hollow ring 12 is provided at one end of the connecting rod 13, and one end of the connecting rod 13 is slidably connected to the inner surface of the hollow ring 12. A pipe pile body 11 is provided at one end of the hollow ring 12, and one end of the hollow ring 12 is fixedly connected to one side of the pipe pile body 11. A side plate 112 is provided on one side of the connecting rod 13, and one side of the connecting rod 13 is fixedly connected to the bottom end of the side plate 112, and one side of the side plate 112 is in sliding contact with the inner wall of the hollow ring 12.

[0026] In this embodiment, the pile body 11 is inserted into the foundation pit to obtain pre-positioning. At this time, the movable arm 15 can be moved to make the cross plate 16 contact the side wall of the foundation pit. In this process, the empty tube 17 on the cross plate 16 will first contact the side wall. When in contact, the cross plate 16 is continuously pushed along the path to make the empty tube 17 enter the side wall of the foundation pit. However, after entering, in order to increase the strength of the structure, an external force is applied to the extrusion rod 19 to make it move in the empty tube 17. During the movement, due to the slope of the end position of the extrusion rod 19, the locking block 18 will be affected by its movement and gradually exposed in the empty tube 17. After being exposed, as the external force does not disappear, it will form a structural bite inside the side wall. This bite effect can increase the strength and stability of the overall structure and provide better foundation support and resistance.

[0027] Secondly, in order to adapt to the size of the foundation pit, when it is necessary to adapt to a larger foundation pit, the connecting rod 13 is pulled out from the hollow ring 12 so that the overall arm span of the connecting rod 13 is extended, so that the supporting structure can cover a larger range of the interior of the foundation pit, thereby adapting to foundation pits of different sizes. At the same time, there are side plates 112 on the connecting rod 13. When extended, the side plates 112 will be adjusted in the same way, and the side plates 112 will always fit with the side walls of the foundation pit, thereby ensuring the close fit between the supporting structure and the side walls of the foundation pit and preventing the soil from tilting or collapsing.

[0028] Example 2

[0029] like Figure 1 - Figure 4 As shown, the fixing mechanism 2 includes an arc plate 21 , an insert plate 22 is arranged at one end of the arc plate 21 , one end of the arc plate 21 is fixedly connected to one end of the insert plate 22 , and the inner side of the arc plate 21 fits with one side of the connecting rod 13 .

[0030] In the present embodiment, after the connecting rod 13 is extended, in order to fix it in the extended position, the arc plate 21 is fitted into the groove corresponding to the connecting rod 13. During the fitting process, the plug plate 22 on the arc plate 21 will gradually enter the side wall of the foundation pit. The arc plate 21 is fixed by the connection between the plug rod and the side wall, so that the connecting rod 13 cannot be moved. This can ensure that the supporting structure maintains a stable position and shape inside the foundation pit, which is particularly important for larger foundation pits or engineering projects that require long-term support.

[0031] Working principle:

[0032] like Figure 1 - Figure 4As shown, by inserting the pipe pile body 11 into the foundation pit, the movable arm 15 can be moved at this time. During this process, the empty pipe 17 on the horizontal plate 16 will first contact the side wall. When in contact, the horizontal plate 16 is continuously pushed along the path so that the empty pipe 17 enters the side wall of the foundation pit. By applying external force to the extrusion rod 19, it is moved in the empty pipe 17. Therefore, the locking block 18 will be affected by its movement and gradually exposed in the empty pipe 17. After being exposed, as the external force does not disappear, it will form a structural bite inside the side wall. Secondly, by pulling out the connecting rod 13 in the hollow ring 12, the overall arm span of the connecting rod 13 is extended, so that the supporting structure can cover a larger range of the inside of the foundation pit, thereby adapting to foundation pits of different sizes.

[0033] The arc plate 21 is matched with the groove corresponding to the connecting rod 13. During the matching process, the plug plate 22 on the arc plate 21 will gradually enter the side wall of the foundation pit. The arc plate 21 is fixed by the connection between the plug rod and the side wall, so that the connecting rod 13 cannot be moved, thereby ensuring that the supporting structure maintains a stable position and shape inside the foundation pit.

[0034] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
