Description

Technical Field

[0001] This utility model relates to the field of land construction technology, specifically a soft soil foundation reinforcement device. Background Technology

[0002] Soft soil foundations are mainly composed of weak soil layers with high water content, large void ratio, high compressibility, low bearing capacity, and slow drainage consolidation, such as silt, silty soil, and fill. In construction projects, if construction is carried out directly on soft soil foundations, the low bearing capacity and high settlement characteristics of the foundation will lead to uneven settlement, tilting, or even structural damage to the buildings. Therefore, it is necessary to reinforce soft soil foundations to improve their bearing capacity, reduce settlement, and ensure the safety and stability of the project.

[0003] Upon investigation, a Chinese utility model patent discloses a foundation reinforcement device for soft soil foundations (publication number: CN221276568U), which includes a foundation pit, a soft soil layer, and a fill layer. The foundation pit contains a soft soil layer, and a fill layer is poured on the outside of the soft soil layer. The foundation pit is equipped with a reinforcement mechanism that can reinforce the soft soil layer according to the height of the foundation pit and is easy to assemble, as well as a connecting mechanism that facilitates the lateral connection of various reinforcement devices.

[0004] Although the aforementioned patent allows for the combined use of mounting bases, anchor rods, mounting grooves, limiting sliding edges, foolproof mounting grooves, reinforcing base columns, foolproof limiting blocks, and limiting sliding grooves, enabling the stacking and installation of reinforcing base columns according to the pit height, thus allowing for corresponding longitudinal reinforcement of the pit and soft soil layer based on the pit height and effectively improving the stability of the soft soil layer, and also allows for the lateral connection of various reinforcement devices to improve the lateral reinforcement efficiency of the soft soil layer and pit, further enhancing the stability of the soft soil layer, it requires excavating the pit foundation for the installation of the reinforcement devices, which consumes a lot of time and labor costs, seriously affecting construction efficiency.

[0005] Therefore, this utility model provides a soft soil foundation reinforcement device to solve the above problems. Utility Model Content

[0016] (III) Beneficial Effects

[0017] 1. By setting concrete piles, reinforcement components and side connection components, the side columns are directly cast and connected to the concrete piles to form vertical and horizontal foundation reinforcement, without the need for foundation excavation, which can effectively reduce time and labor costs, thereby improving construction efficiency. At the same time, the setting of reinforcing bars and vertical bars can effectively improve the stress strength of the side columns and concrete piles, further improving the foundation reinforcement effect.

[0018] 2. By using the bottom connection component, downward pressure can be applied to the top plate during the concrete pile pouring, causing the pressure bar to move downward and thus driving the extension bar to extend outward. This increases the lateral expansion area of ​​the insertion bolt, thereby improving the contact area and interlocking force between it and the surrounding soil or structure. This effectively enhances the overall lateral stability and anti-lateral displacement ability of the column shell without adding extra construction procedures, thus effectively improving construction efficiency and structural safety.

[0026] 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.

[0027] This utility model provides a soft soil foundation reinforcement device, such as... Figures 1-5 As shown, the soft soil foundation reinforcement device includes a column shell 1, a concrete pile 2 is poured inside the column shell 1, a reinforcement component is fixedly connected inside the concrete pile 2, side holes are opened around the outer surface of the column shell 1, side connection components are poured inside the side holes, and a bottom connection component is fixedly connected to the lower surface of the column shell 1.

[0028] The side-connecting component includes a side column 3, one end of which is cast into the interior of a side hole. A reinforcing rib 4 is fixedly connected inside the side column 3, and a protruding rod 5 is fixedly connected to the outer surface of the reinforcing rib 4. The side column 3 is a concrete column, and it can be directly cast and connected to the concrete pile 2 to form vertical and horizontal foundation reinforcement without the need for foundation excavation, which can effectively reduce time and labor costs and improve construction efficiency. At the same time, the protruding rod 5 can increase the bearing area of ​​the reinforcing rib 4 and the side column 3, which can effectively increase the bearing strength of the side column 3 and further improve the foundation reinforcement effect.

[0029] The reinforcement component includes an outer frame 6, the outer surface of which is fixedly connected to the interior of the concrete pile 2. A vertical reinforcement bar 7 is fixedly connected inside the outer frame 6, and an inner frame 8 is fixedly connected inside the vertical reinforcement bar 7. The outer frame 6 connects several vertical reinforcement bars 7 to increase their load-bearing capacity. The inner frame 8 further enhances the load-bearing capacity of the vertical reinforcement bars 7, preventing them from bending. This effectively increases the load-bearing strength of the concrete pile 2 and further improves the foundation reinforcement effect.

[0030] The outer frame 6, the vertical reinforcement 7, and the inner frame 8 are all in a number and arranged in an array. All the joints are welded together. The three are welded together to form a steel cage, which can effectively enhance the stress strength of the concrete pile 2.

[0031] The bottom connection assembly includes an insertion bolt 9, the upper surface of which is fixedly connected to the lower surface of the column shell 1. A spring 10 is fixedly connected to the inner bottom wall of the insertion bolt 9, and a base plate 11 is fixedly connected to the top of the spring 10. A pressure rod 12 is fixedly connected to the upper surface of the base plate 11. A square groove is formed on the outer surface of the pressure rod 12, and an extension rod 13 is rotatably connected inside the square groove. A top plate 14 is fixedly connected to the top of the pressure rod 12. When the insertion bolt 9 moves downward, the spring 10 pushes the base plate 11, and the pressure rod 12 drives the extension rod 13 to retract inward, so that the insertion bolt 9 can be smoothly inserted into the foundation. When the concrete pile 2 is poured, it can exert downward pressure on the top plate 14, so that the pressure rod 12 moves downward, thereby driving the extension rod 13 to extend outward, which increases the lateral expansion area of ​​the insertion bolt 9, thereby increasing its contact area and interlocking force with the surrounding soil or structure. This effectively enhances the overall lateral stability and anti-lateral displacement ability of the column shell 1, without adding extra construction procedures, and effectively improves construction efficiency and structural safety.

[0032] The outer surface of the insertion plug 9 has a through groove that matches the movement trajectory of the extension rod 13. One end of the extension rod 13 is fixedly connected to a limiting plate 15. The limiting plate 15 prevents the extension rod 13 from completely entering the insertion plug 9, causing jamming and preventing it from fully unfolding.

[0033] The inner wall of the column shell 1 is provided with a guide groove, and a pressure plate 16 is slidably connected inside the guide groove. The lower surface of the pressure plate 16 contacts the upper surface of the top plate 14, so that when the concrete pile 2 is poured, a uniform downward pressure can be formed on the top plate 14.

[0034] Working steps: First, use a drilling rig to form a pile pit that matches the column shell 1, and then place the column shell 1 inside the pile pit. At this time, the spring 10 pushes the bottom plate 11, and the extension rod 13 can be driven to retract inward through the pressure rod 12 to facilitate the smooth insertion of the insertion bolt 9 into the foundation. Next, the pressure plate 16 is slid into the column shell 1 along the guide groove, and then a lateral column pit is formed along the side hole using a directional drilling rig. Subsequently, the reinforcing bar 4 is placed inside the column pit, and then the steel cage formed by welding the outer frame 6, the vertical bar 7, and the inner frame 8 is placed inside the pile pit. Next, concrete is poured to form the side column 3 and the concrete pile 2. Finally, when the concrete pile 2 is poured, it can exert downward pressure on the top plate 14 to make the pressure rod 12 move downward, thereby driving the extension rod 13 to extend outward, which can increase the lateral unfolding area of ​​the insertion bolt 9, thereby enhancing the overall lateral stability and anti-lateral displacement ability of the column shell 1.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
