Description

Technical Field

[0001] This utility model belongs to the field of static pressure steel pipe pile technology, specifically relating to a shallow-buried foundation static pressure steel pipe pile reinforcement structure. Background Technology

[0002] The excavation and support work of the foundation pit will cause stress redistribution in the surrounding soil, resulting in soil displacement and ground settlement. For shallow foundation buildings adjacent to the foundation pit, due to their shallow foundation depth, they are more sensitive to soil displacement and are therefore more susceptible to the impact of construction disturbance. In addition, changes in soft strata and groundwater levels will further exacerbate the safety hazards of the buildings.

[0003] Static pressure steel pipe piles are a common method of foundation reinforcement. Due to their advantages such as simple construction, high bearing capacity and strong adaptability, they have been widely used in foundation pit construction. However, in the reinforcement scenario of buildings adjacent to shallow foundations, static pressure steel pipe piles also face many challenges, such as encountering soft strata and shallow burial conditions, which can reduce the overall stability of the pile body. To address this, this utility model proposes a static pressure steel pipe pile reinforcement structure for shallow foundations. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example

[0024] Please see Figures 1 to 4 This is an embodiment of the present utility model, which provides a technical solution: a shallow-buried foundation static pressure steel pipe pile reinforcement structure, including...

[0025] A reinforcing top ring 1, a reinforcing bottom ring 51, and a reinforcing support sleeve 52 are fitted onto the bottom surface of the pile body 4. A circular bottom groove 31 corresponding to the reinforcing top ring 1 and the reinforcing bottom ring 51 is opened on the surface of the foundation 3. The reinforcing top ring 1, the reinforcing bottom ring 51, and the reinforcing support sleeve 52 are all located in the circular bottom groove 31. After the three are combined, the circular bottom groove 31 can be sealed and the foundation part at the bottom of the pile body 4 can be effectively reinforced and supported.

[0026] The reinforcing bottom ring 51 and the reinforcing support sleeve 52 are an integral structure;

[0027] Two disassembly and assembly mechanisms 2 are provided on the reinforcing top ring 1 for disassembly and assembly between the reinforcing top ring 1 and the reinforcing support sleeve 52.

[0028] In this embodiment, preferably, a plurality of connecting blocks 53 are welded and fixed on the top surface of the reinforcing support sleeve 52, and a plurality of slots 11 for the connecting blocks 53 to be inserted are opened on the bottom surface of the reinforcing top ring 1, so that after the reinforcing top ring 1 and the reinforcing support sleeve 52 are fitted together, the connecting blocks 53 can be inserted into the slots 11, thereby further improving the connection effect between the reinforcing top ring 1 and the reinforcing support sleeve 52.

[0029] In this embodiment, preferably, the disassembly and assembly mechanism 2 includes a connecting shaft 22 rotatably disposed inside the reinforcing top ring 1. The top end of the connecting shaft 22 extends through to the top of the reinforcing top ring 1 and is fixed with a rotating top bar 21. The bottom end of the connecting shaft 22 extends through to the bottom of the reinforcing top ring 1 and is fixed with a rotating base 23. A limit strip 24 is fixed on the surface of the rotating base 23. An annular groove 54 corresponding to the limit strip 24 is opened on the top surface of the reinforcing support sleeve 52. The end of the limit strip 24 is screwed into the annular groove 54 to realize the connection between the reinforcing top ring 1 and the reinforcing support sleeve 52, preventing the reinforcing top ring 1 from moving up and down and ensuring the stability of the reinforcing structure. Subsequently, it is only necessary to push the rotating top bar 21 to make the connecting shaft 22 rotate with the rotating base 23, causing the end of the limit strip 24 to move out of the annular groove 54, so that the reinforcing top ring 1 is no longer limited. Then the reinforcing top ring 1 can be moved up and separated from the reinforcing support sleeve 52.

[0030] In this embodiment, preferably, the surface of the reinforcing top ring 1 has two circular rod holes through which the connecting shaft 22 passes.

[0031] In this embodiment, preferably, the disassembly and assembly mechanism 2 further includes an inner groove 25 formed inside the reinforcing top ring 1. A spring 26 and a hemispherical telescopic block 27 are provided in the inner groove 25. The bottom surface of the rotating top bar 21 is provided with a limiting slot 28 corresponding to the hemispherical telescopic block 27. The hemispherical telescopic block 27 is movably installed in the inner groove 25 by the spring 26, and the top of the hemispherical telescopic block 27 pops out into the limiting slot 28, which can lock and limit the rotating top bar 21 to prevent the rotating top bar 21 from rotating on its own. If the operator wants to push the rotating top bar 21 to achieve the rotation of the limiting slot 24, he only needs to push the rotating top bar 21 with force so that the top of the hemispherical telescopic block 27 is gradually squeezed into the inner groove 25, so that the rotating top bar 21 can rotate smoothly, and the connecting shaft 22, the rotating base 23 and the limiting slot 24 can rotate smoothly.

[0032] In this embodiment, preferably, the bottom end of the spring 26 is fixed to the inner wall of the bottom end of the inner groove 25, and the top end of the spring 26 is fixed to the bottom end of the hemispherical telescopic block 27.

[0033] In this embodiment, preferably, the inner wall of the top end of the inner groove 25 is provided with a pop-out hole that communicates with the top surface of the reinforcing top ring 1, and the size of the pop-out hole is adapted to the top end size of the hemispherical telescopic block 27, so that the top end of the hemispherical telescopic block 27 can pop out smoothly.

[0034] In this embodiment, preferably, the inner diameters of the reinforcing top ring 1, the reinforcing bottom ring 51, and the reinforcing support sleeve 52 are all adapted to the pile body 4 to allow the pile body 4 to pass through smoothly.

[0035] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
