Description

Technical Field

[0001] This utility model relates to the field of soft soil foundation technology, and in particular to a reinforcement structure. Background Technology

[0002] With the rapid development of coastal port, industrial building, and highway construction projects, especially some projects that need to be built in areas with deep soft soil, the high porosity of soft soil in its microstructure is an important factor affecting its compression deformation, resulting in high compressibility, low shear strength and poor permeability of soft soil. Therefore, it is necessary to reinforce deep soft soil.

[0003] For example, Chinese utility model patent (CN207032204U) discloses a composite structure for treating soft soil foundations, which describes: "It includes bearing piles, pile caps, reinforcement layers, and backfill compacted pads. The bearing piles are arranged vertically along the depth of the soft soil foundation, and the pile caps are connected to the upper end of the bearing piles. The reinforcement layer is laid on the soft soil foundation and covers the top surface of the pile caps. The backfill compacted pads are laid on the reinforcement layer, forming the entire composite structure from top to bottom. The bearing piles penetrate the weak soil layer and act on the underlying bearing soil layer. The foundation load is transferred from the weak soil layer to the underlying bearing soil layer through the composite structure. This not only achieves the effect of reinforcing the soft soil foundation, but also reduces the number of processes, shortens the construction time, and improves work efficiency."

[0004] However, the multiple load-bearing piles in the above-mentioned patents are independent of each other, resulting in dispersed bearing capacity and weak support stability for soft soil foundations. Therefore, this application proposes a reinforcement structure. Utility Model Content

[0005] Based on this, it is necessary to provide a reinforcement structure to address the aforementioned technical problems. Through the overall structural design, multiple load-bearing piles are interconnected by multiple triangular linkage components, which greatly improves the longitudinal bearing capacity. This results in a concentrated bearing capacity and stronger support stability compared to existing technologies, effectively enhancing the overall reinforcement effect.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A reinforcement structure applied to soft soil foundations;

[0008] The system includes a composite soft soil foundation and multiple bearing piles embedded in the composite soft soil foundation. Each bearing pile is provided with a pile cap at its upper end. Each bearing pile is fixed with a clamp at its outer side and at the lower end of the pile cap. An I-beam is welded and fixed between every two clamps. A triangular connecting rod assembly is provided between every two I-beams.

[0009] Each of the triangular connecting rod assemblies includes a channel steel seat, and a channel steel seat is provided between every two I-beams. Two limiting guide posts are fixed on the inner side of the channel steel seat, and a steel plate is slidably connected between the two limiting guide posts on the outer side. The outer side of the steel plate is in contact with the inner side of the channel steel seat. A first V-shaped reinforcing frame is fixed at the center of the outer side of the steel plate and on the outer side of the channel steel seat. A second V-shaped reinforcing frame is fixed at the center of the end of the channel steel seat away from the first V-shaped reinforcing frame.

[0010] As a preferred embodiment of the reinforcement structure provided by this utility model, the end of the first V-shaped reinforcing frame away from the steel plate and the end of the second V-shaped reinforcing frame away from the channel steel seat are respectively located inside the two I-beams and slidably connected to the I-beams. Both sides of the end of the first V-shaped reinforcing frame away from the steel plate and both sides of the end of the second V-shaped reinforcing frame away from the channel steel seat are fitted with the clamp.

[0011] As a preferred embodiment of the reinforcement structure provided by this utility model, a high-strength spring is sleeved on the outside of each of the limiting guide posts. One end of the high-strength spring is fixed to the channel steel seat, and the other end of the high-strength spring is fixed to the steel plate.

[0012] As a preferred embodiment of the reinforcement structure provided by this utility model, a hollow storage cylinder is fixed to the outer side of the lower end of each bearing pile, and multiple long bolts are uniformly fixed to the inner side of the hollow storage cylinder and the outer side of the bearing pile.

[0013] As a preferred embodiment of the reinforcement structure provided by this utility model, a flange is fitted on the outer side of each of the bearing piles and at the upper end of the hollow storage cylinder. The bottom end of the flange is in contact with the hollow storage cylinder, and the upper ends of the plurality of long bolts penetrate the flange and are fixedly connected to the flange.

[0014] As a preferred embodiment of the reinforcement structure provided by this utility model, each of the bearing piles has multiple insert rods fixed at its bottom end.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The reinforcement structure provided by this utility model, through the overall structural design, enables multiple load-bearing piles to be interconnected by multiple triangular connecting rod components, which greatly improves the longitudinal bearing capacity. This makes the bearing capacity of the structure concentrated and the support stability stronger than the prior art, effectively improving the overall reinforcement effect.

[0017] The hollow storage tank facilitates concrete filling, thereby further enhancing the strength of individual load-bearing piles. The flange allows for easy sealing of the hollow storage tank and facilitates flexible assembly and disassembly of the triangular connecting rod assembly between the two I-beams, effectively shortening the construction period and improving efficiency.

[0026] As described in the background section, the multiple bearing piles in the aforementioned patent are independent of each other, resulting in dispersed bearing capacity and weak support stability for soft soil foundations.

[0027] To solve this technical problem, this utility model provides a reinforcement structure that is applied to soft soil foundations;

[0028] The system includes a composite soft soil foundation 1 and multiple bearing piles 2 embedded in the composite soft soil foundation 1. Each bearing pile 2 is provided with a pile cap 3 at its upper end. Each bearing pile 2 is fixed with a clamp 8 on its outer side and at the lower end of the pile cap 3. An I-beam 9 is welded and fixed between every two clamps 8. A triangular connecting rod assembly 10 is provided between every two I-beams 9.

[0029] Each triangular linkage assembly 10 includes a channel steel seat 11. A channel steel seat 11 is provided between every two I-beams 9. Two limiting guide posts 12 are fixed on the inner side of the channel steel seat 11. A steel plate 13 is slidably connected on the outer side between the two limiting guide posts 12. The outer side of the steel plate 13 is in contact with the inner side of the channel steel seat 11. A first V-shaped reinforcing frame 14 is fixed at the center of the outer side of the steel plate 13 and on the outer side of the channel steel seat 11. A second V-shaped reinforcing frame 16 is fixed at the center of the end of the channel steel seat 11 away from the first V-shaped reinforcing frame 14.

[0030] The reinforcement structure provided by this utility model, through the overall structural design, enables multiple load-bearing piles 2 to be interconnected by multiple triangular connecting rod components 10, which greatly improves the longitudinal bearing capacity. This makes the bearing capacity of the structure concentrated and the support stability stronger than the prior art, effectively improving the overall reinforcement effect.

[0031] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0032] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0033] Example 1:

[0034] Please refer to Figure 1-5 A reinforcement structure includes a composite soft soil foundation 1 and multiple bearing piles 2 embedded in the composite soft soil foundation 1. Each bearing pile 2 has a pile cap 3 at its upper end. When embedding the bearing piles 2, in order to facilitate the insertion of the bearing piles 2 into the composite soft soil foundation 1, multiple insertion rods 4 are fixed at the bottom end of each bearing pile 2. A clamp 8 is fixed on the outside of each bearing pile 2 and at the lower end of the pile cap 3. In order to facilitate the interconnection of multiple bearing piles 2, concentrate the bearing capacity between multiple bearing piles 2, and improve the support stability, an I-beam 9 is welded and fixed between every two clamps 8. A triangular connecting rod assembly 10 is provided between every two I-beam 9.

[0035] Specifically, each triangular linkage assembly 10 includes a channel steel seat 11. A channel steel seat 11 is provided between every two I-beams 9. Two limiting guide posts 12 are fixed on the inner side of the channel steel seat 11. A steel plate 13 is slidably connected to the outer side between the two limiting guide posts 12. The outer side of the steel plate 13 is in contact with the inner side of the channel steel seat 11. A first V-shaped reinforcing frame 14 is fixed at the center of the outer side of the steel plate 13 and on the outer side of the channel steel seat 11. A second V-shaped reinforcing frame 16 is fixed at the center of the end of the channel steel seat 11 away from the first V-shaped reinforcing frame 14. The end of the first V-shaped reinforcing frame 14 away from the steel plate 13 and the end of the second V-shaped reinforcing frame 16 away from the channel steel seat 11 are respectively located on the inner side of the two I-beams 9 and slidably connected to the I-beams 9.

[0036] To prevent the triangular linkage assembly 10 from sliding laterally between the two I-beams 9, the two sides of the first V-shaped reinforcing frame 14 away from the steel plate 13 and the two sides of the second V-shaped reinforcing frame 16 away from the channel steel seat 11 are fitted with the clamp 8. When installing the triangular linkage assembly 10, the steel plate 13 needs to be squeezed so that the first V-shaped reinforcing frame 14 and the second V-shaped reinforcing frame 16 are close to each other, so as to facilitate the placement of the triangular linkage assembly 10 between the two I-beams 9. When the steel plate 13 is released, in order to facilitate its automatic reset, a high-strength spring 15 is fitted on the outside of each limiting guide post 12. One end of the high-strength spring 15 is fixed to the channel steel seat 11, and the other end of the high-strength spring 15 is fixed to the steel plate 13.

[0037] Example 2:

[0038] The reinforcement structure provided in Example 1 is further optimized, specifically, as follows: Figure 3-4 As shown, in order to further enhance the strength of a single bearing pile 2, a hollow storage cylinder 5 is fixed to the outer side of the lower end of each bearing pile 2. The hollow storage cylinder 5 facilitates the filling of concrete. Multiple long bolts 6 are evenly fixed to the inner side of the hollow storage cylinder 5 and the outer side of the bearing pile 2. After the concrete is filled, in order to seal the hollow storage cylinder 5, a flange 7 is fitted to the outer side of each bearing pile 2 and the upper end of the hollow storage cylinder 5. The bottom end of the flange 7 fits into the hollow storage cylinder 5, and the upper ends of the multiple long bolts 6 penetrate the flange 7 and are fixedly connected to the flange 7.

[0039] The process of using the reinforcement structure provided by this utility model is as follows: Multiple bearing piles 2 are embedded in the composite soft soil foundation 1, and both sides of multiple I-beams 9 are welded and fixed to clamps 8. Then, the triangular connecting rod assembly 10 is installed. First, the steel plate 13 is pressed to compress the high-strength spring 15 and slide, thereby causing the first V-shaped reinforcing frame 14 and the second V-shaped reinforcing frame 16 to move closer to each other, making it convenient to place the triangular connecting rod assembly 10 between the two I-beams 9. Then, the steel plate 13 is released, and the high-strength spring 15... The elasticity causes the steel plate 13 to reset, which in turn causes the ends of the first V-shaped reinforcing frame 14 and the second V-shaped reinforcing frame 16 to be respectively attached to the inner sides of the two I-beams 9. Both sides of the first V-shaped reinforcing frame 14 and the second V-shaped reinforcing frame 16 are attached to the clamps 8, completing the installation of the triangular connecting rod assembly 10. This allows multiple load-bearing piles 2 to be interconnected by multiple triangular connecting rod assemblies 10, greatly improving the longitudinal bearing capacity. This makes the bearing capacity of the structure concentrated and provides strong support stability compared to existing technologies, effectively improving the overall reinforcement effect.
