Abstract
Description
Technical Field
[0001] This invention relates to the field of soft soil foundation excavation, and particularly to a structural frame for preventing steel sheet piles from being squeezed and deformed in soft soil foundations. Background Technology
[0002] Soft soil refers to fine-grained soil deposited in coastal areas, lakes, valleys, and riverbanks, characterized by high natural water content, large void ratio, high compressibility, and low shear strength. It is characterized by high natural water content, large natural void ratio, high compressibility, low shear strength, small consolidation coefficient, long consolidation time, high sensitivity, large disturbance, poor permeability, complex layered distribution, and significant differences in physical and mechanical properties between layers.

[0017] Beneficial effects
[0018] Compared with the prior art, the present invention provides a structural frame for preventing the extrusion deformation of steel sheet piles in soft soil foundations, which has the following beneficial effects:
[0019] 1. The soft soil foundation uses a structural frame to prevent the sheet piles from being squeezed and deformed. The frame body can be lifted by the lifting rings, which makes it easy to install the frame body at the excavation site. The frame body can also be wrapped around the workers excavating in the foundation, thus protecting them and ensuring their safety during work.
[0020] 2. The structural frame used in this soft soil foundation to prevent deformation of sheet piles is equipped with buffer components. When the buried piles need to be buried, the frame can buffer the structure itself. When the top plate is used to drive the frame to the bottom with external tools, the connecting columns and limiting blocks can buffer the springs. This effectively protects the stability of the structure and improves its overall service life. At the same time, the fixed columns guide the movement of the connecting columns and limiting blocks, thus preventing the connecting columns from breaking due to displacement.
[0021] 3. The soft soil foundation uses a structural frame to prevent the sheet piles from being squeezed and deformed. Through the setting of ventilation holes and ventilation grooves, it can achieve the effect of ventilation when workers are working. At the same time, the first hydraulic cylinder is activated, so that the first hydraulic rod can fit against the front of the inner cavity of the ventilation groove. At this time, it can provide a support effect on the front and back of the structural frame body. After the structural frame body is buried in the soft soil, it can prevent the structural frame body from deforming, thereby protecting the workers inside.
[0022] 4. The soft soil foundation uses a structural frame to prevent the sheet piles from being squeezed and deformed. Through the set chute and guide column, when the first hydraulic rod moves, it will drive the slider to move in the inner cavity of the chute and the outer wall of the guide column through the connecting block. At the same time, it will drive the roller to slide at the bottom of the inner cavity of the chute, thereby ensuring the smooth movement of the first hydraulic rod. In conjunction with the set support column, it can support the first hydraulic cylinder and the first hydraulic rod, and also further reinforce the first hydraulic cylinder and the first hydraulic rod.
[0023] 5. The soft soil foundation uses a structural frame to prevent deformation caused by the extrusion of sheet piles. Through the second hydraulic cylinders and second hydraulic rods on both sides, in conjunction with the second fixing frame, the two sides of the structural frame body can be supported, preventing deformation of the two sides of the structural frame body due to the soft soil. The handles provided allow workers to grab the handles and leave with the hoisted structural frame body after leaving the excavated foundation. It also facilitates the workers' departure after the work is completed. Attached Figure Description

Detailed Implementation
[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0031] like Figure 1-3 As shown, a structural frame for preventing sheet pile compression deformation in soft soil foundations includes a structural frame body 1. Buffer components 5 are symmetrically fixedly connected to the top perimeter of the structural frame body 1. A top plate 2 is provided on the top of the buffer components 5. A ventilation hole 4 is opened in the center of the top plate 2. Four lifting rings 3 are symmetrically fixedly connected to the top perimeter of the top of the top plate 2. A limiting groove 6 is opened in the center of the top of the buffer components 5. A fixing column 7 is fixedly connected to the center of the bottom of the inner cavity of the buffer components 5. A spring 8 is wound around the outer wall of the fixing column 7. The bottom of the spring 8 is fixedly connected to the bottom of the inner cavity of the buffer components 5. A limiting block 9 is fixedly connected to the top of the spring 8. A connecting column 10 is fixedly connected to the center of the top of the limiting block 9. The top of the connecting column 10 is fixedly connected to the bottom of the top plate 2. Both the limiting block 9 and the connecting column 10 are fitted onto the outer wall of the fixing column 7.
[0032] The lifting ring 3 allows the structural frame body 1 to be lifted, facilitating its installation at the excavation site. The structural frame body 1 can also be wrapped around the workers excavating within the foundation, protecting them and ensuring their safety. The buffer component 5 provides cushioning when the buried column 11 needs to be buried. When external tools are used to drive the top plate 2 and the structural frame body 1 downwards, the connecting column 10 and the limiting block 9 cushion the spring 8, effectively protecting the structural stability and extending its service life. The fixing column 7 guides the movement of the connecting column 10 and the limiting block 9, preventing the connecting column 10 from breaking due to misalignment.
[0033] like Figure 1 , 3 As shown in Figures 4 and 5, a structural frame for preventing sheet pile compression deformation in soft soil foundations is provided. The bottom of the structural frame body 1 is symmetrically threaded with buried columns 11. A ventilation groove 12 is provided in the center of the top of the structural frame body 1. A first hydraulic cylinder 13 is fixedly connected to the back of the inner cavity of the ventilation groove 12. A first hydraulic rod 14 is installed in the inner cavity of the first hydraulic cylinder 13. A support column 15 is fixedly connected to the bottom of the first hydraulic cylinder 13. There are eight first hydraulic cylinders 13 and eight first hydraulic rods 14. The back of each first hydraulic cylinder 13 is symmetrically fixedly connected to the back of the inner cavity of the ventilation groove 12. There are eight support columns 15. The front and back sides of the support column 15 are symmetrically fixed to the top of the inner cavity of the structural frame body 1. The front of the top of the support column 15 is provided with a sliding groove 16. A guide column 17 is fixedly connected in the inner cavity of the sliding groove 16. A connecting block 18 is fixedly connected to the front of the bottom of the first hydraulic rod 14. A slider 19 is fixedly connected to the center of the bottom of the connecting block 18. A roller 20 is rotatably connected to the bottom of the inner cavity of the slider 19. The slider 19 is movably connected in the inner cavity of the sliding groove 16. The bottom of the roller 20 is attached to the bottom of the inner cavity of the sliding groove 16. The slider 19 is sleeved on the outer wall of the guide column 17. The front of the first hydraulic rod 14 is attached to the front of the inner cavity of the vent groove 12.
[0034] The ventilation holes 4 and ventilation grooves 12 provide ventilation for workers. Simultaneously, the first hydraulic cylinder 13 is activated, allowing the first hydraulic rod 14 to fit against the front of the ventilation groove 12. This provides support for the front and back of the structural frame 1, preventing structural deformation after the structural frame 1 is buried in soft soil, thus protecting the workers inside. The sliding groove 16 and guide post 17, when the first hydraulic rod 14 moves, drive the slider 19 via the connecting block 18 to move within the sliding groove 16 and along the outer wall of the guide post 17. This also causes the roller 20 to slide at the bottom of the sliding groove 16, ensuring the smooth movement of the first hydraulic rod 14. Combined with the support post 15, this provides support for the first hydraulic cylinder 13 and the first hydraulic rod 14, further reinforcing them.
[0035] like Figure 1 , 3 As shown, a structural frame for preventing sheet pile compression deformation in soft soil foundations is provided. The frame body 1 has two symmetrically arranged second hydraulic cylinders 25 on both sides of its inner cavity. A second hydraulic rod 26 is installed inside the inner cavity of each second hydraulic cylinder 25. A handle 27 is fixedly connected to the inner cavity of the frame body 1. A through groove 22 is formed in the center of the bottom of the inner cavity of the frame body 1. A first fixing frame 23 is symmetrically fixedly connected to the front and back sides of the bottom left and right sides of the inner cavity of the frame body 1. A second fixing frame 24 is symmetrically fixedly connected to the front and back sides of the left and right sides of the inner cavity of the frame body 1. There are four second hydraulic cylinders 25 and four second hydraulic rods 26. The bottom of the second hydraulic cylinder 25 is fixedly connected to the inner cavity of the first fixing frame 23, and the top of the second hydraulic cylinder 25 is fixedly connected to the inner cavity of the second fixing frame 24. A controller 21 is fixedly connected to the left side of the inner cavity of the frame body 1. There are four handles 27, symmetrically fixedly connected to the left and right sides of the front and back sides of the inner cavity of the frame body 1.
[0036] The second hydraulic cylinders 25 and second hydraulic rods 26 set on both sides, together with the second fixing frame 24, can support the two sides of the structural frame body 1, and prevent the two sides of the structural frame body 1 from deforming due to soft soil. The handles 27 set on both sides can be grabbed by the workers when they need to leave the excavated foundation and leave together with the hoisted structural frame body 1. It is also convenient for the workers to leave after the work is completed.
[0037] It should be noted that this invention is a structural frame for preventing sheet piles from being squeezed and deformed in soft soil foundations. During use, workers enter the soft soil foundation to be excavated, lift the top plate 2 and the structural frame body 1 using the lifting ring 3, and slowly place the structural frame body 1 into the soft soil foundation. Using external tools, the buried column 11 is inserted into the ground. After the top plate 2 is compressed, it will drive the connecting column 10 and the limiting block 9 to move towards the bottom of the inner cavity of the buffer assembly 5. At this time, the limiting block 9 will compress the spring 8, and simultaneously, the limiting block 9 and the connecting column 10 will move on the outer wall of the fixed column 7. Once the buried column 11 is buried in the ground, the initial installation of the structural frame body 1 is completed, and the first... Hydraulic cylinder 13 drives the first hydraulic rod 14 forward. When the first hydraulic rod 14 moves, the connecting block 18 drives the slider 19 to move in the inner cavity of the slide groove 16 and the outer wall of the guide column 17 until the first hydraulic rod 14 moves to the front of the inner cavity of the ventilation groove 12. At this time, the first hydraulic cylinder 13 and the first hydraulic rod 14 can support the front and back of the structural frame body 1. The second hydraulic cylinder 25 and the second hydraulic rod 26 are activated. The second hydraulic rod 26 supports the two sides of the structural frame body 1 through the second fixed frame 24, thereby completing the protective treatment of the structural frame body 1. At this time, the workers can carry out the excavation work for installation on the soft soil foundation.
