Description
Technical Field
[0001] This utility model relates to the field of composite carrier pile technology, specifically a multi-segment combined composite carrier pile. Background Technology
[0002] A carrier pile is a pile foundation structure consisting of a concrete pile body and a bearing body. The bearing body is composed of three parts: concrete, compacted fill material, and compacted soil, forming a composite spread foundation. This type of pile is suitable for soil layers such as silt, sand, gravel, and plastic to stiff plastic cohesive soil. Tests have verified that it can also be applied to plain fill, miscellaneous fill, and collapsible yellow soil. The spacing between carrier piles should not be less than 3 times the pile diameter, and the construction of the carrier pile should not affect the construction quality of adjacent piles. When the soil layer to be reinforced is silt, sand, or gravel, the pile spacing should not be less than 1.6m; when the soil layer to be reinforced is cohesive soil with high water content, the pile spacing should not be less than 2.0m.
[0003] Existing composite carrier piles suffer from problems such as long construction cycles and high costs during use, and are difficult to adapt to the different bearing requirements of soil layers at different depths in river restoration. Therefore, there is an urgent need for a multi-segment combined composite carrier pile to improve the above problems. Utility Model Content

[0024] Example 1 Reference Figure 1 , Figure 2 and Figure 3 This utility model discloses a multi-segment combined composite carrier pile, including a column 1. The column 1 has a positioning structure 2 inside, which includes an installation cavity 3 and an extension cylinder 4. The installation cavity 3 has a positioning hole 5 and a limiting groove 6 inside, and an installation block 7 inside. The installation block 7 has a sliding groove 8 inside, and a spring rod 9 inside the sliding groove 8. The output shaft of the spring rod 9 is provided with a limiting plate 10. The top of the installation block 7 is provided with a positioning shaft 11. The outer side of the extension cylinder 4 has an inclined surface A12, and the inside of the column 1 has an inclined surface B13. In this embodiment, the installation cavity 3 serves as a connecting structure, the extension cylinder 4 serves as a positioning structure, and the positioning hole 5 facilitates the connection of the positioning shaft 11.
[0025] Reference Figure 2 and Figure 3 The extension tube 4 is fixedly connected to the column 1. The mounting cavity 3 is opened inside the column 1. The mounting block 7 is fixedly connected to the top of the column 1. The positioning hole 5 is adapted to the positioning shaft 11. The limiting groove 6 is adapted to the limiting plate 10. In this embodiment, the mounting block 7 plays the role of mounting the positioning shaft 11, the limiting groove 6 plays the role of locking the limiting plate 10, the positioning hole 5 plays the role of limiting, and the limiting plate 10 plays the role of locking the column 1.
[0026] Reference Figure 2 and Figure 3 One end of the spring rod 9 is fixedly connected to the inside of the slide groove 8, and the other end of the spring rod 9 is fixedly connected to the limiting plate 10. The limiting plate 10 is slidably connected to the inside of the slide groove 8. The inclined surface A12 and the inclined surface B13 are adapted to each other. In this embodiment, the slide groove 8 serves to install the spring rod 9 and facilitates the sliding of the limiting plate 10. The spring rod 9 facilitates the sliding of the limiting plate 10. The inclined surfaces A12 and B13 both facilitate the connection.
[0027] Reference Figure 4 and Figure 5A fixing structure 14 is provided on the outer side of the column 1. The fixing structure 14 includes a through hole 15 and a screw hole 16. A fixing screw 17 is provided inside the screw hole 16. A washer 18 is provided on the outer side of the fixing screw 17. A flange plate 19 is provided on the top of the washer 18. A fixing bolt 20 is provided inside the flange plate 19. In this embodiment, the through hole 15 serves to facilitate the passing of the fixing screw 17, and the screw hole 16 serves to connect the fixing screw 17.
[0028] Reference Figure 4 and Figure 5 The through hole 15 is opened inside the column 1, the screw hole 16 is opened inside the extension tube 4, the fixing screw 17 is adapted to the screw hole 16, and the washer 18 is snapped onto the outside of the fixing screw 17. In this embodiment, the washer 18 plays the role of preventing the fixing screw 17 from sliding.
[0029] Reference Figure 4 and Figure 5 The flange plate 19 is fixedly connected to the outside of the column 1, and the fixing bolt 20 is snapped into the inside of the flange plate 19. In this embodiment, the flange plate 19 serves to facilitate the interconnection of the columns 1, and the fixing bolt 20 serves to fix the flange plate 19.
[0030] Reference Figure 6 A waterproof coating 21 is provided on the outer side of the column 1, and a wear-resistant coating 22 is provided on the outer side of the waterproof coating 21. In this embodiment, the waterproof coating 21 serves to protect the column 1, and the wear-resistant coating 22 serves to improve wear resistance.
[0031] The implementation principle of this embodiment is as follows: During use, a lifting device is needed to lift column 1 so that column 1 is in a vertical state. When column 1 is suspended in the air and in a vertical state, the lifting device will drive column 1 to move downward (column 1 is concentric with the reserved hole). As column 1 moves downward, column 1 will gradually enter the reserved hole, thereby playing the role of bearing pressure. When faced with pre-drilled holes of varying depths, multiple columns 1 need to be spliced together. During the splicing process, the distance between two columns 1 gradually decreases until they are fitted together. At this point, the flange plates 19 mounted on the outer sides of the two columns 1 will be in a fitted state. After the columns 1 are stationary, the workers install the fixing bolts 20 into the inside of the flange plates 19 and tighten them. After the fixing bolts 20 are installed into the inside of the flange plates 19, the gaskets 18 are fitted onto the outside of the fixing screws 17 that need to be installed, and the fixing screws 17 pass through the through holes 15 and into the screw holes 16 (again, the workers need to tighten them with tools). By utilizing the threaded engagement between the screw holes 16 and the fixing screws 17, the two columns 1 can be fixed together, which can effectively prevent the columns 1 from loosening during use. During the splicing of the two columns 1, the extension cylinder 4 located on the upper column 1 will be inserted into the interior of the lower column 1. During this process, the positioning shaft 11 will first enter the interior of the mounting groove, and then enter the interior of the positioning hole 5. As the positioning shaft 11 slides inside the positioning hole 5, the mounting block 7 will gradually enter the interior of the mounting cavity 3. At the same time, since the limiting plate 10 is in an inclined state, as the distance between the two columns 1 continues to decrease, the pressure generated by their movement will push the limiting plate 10 into the interior of the limiting groove 6. As the limiting plate 10 slides into the sliding groove 8... The output shaft of the spring rod 9 will be gradually compressed, and the extension tube 4 will be fully inserted into the interior of another column 1. At this time, the output shaft of the spring rod 9 will quickly extend outward and push the limiting plate 10 out of the slide groove 8 and into the interior of the limiting groove 6 (after the spring rod 9 pushes the limiting plate 10 into the interior of the limiting groove 6, a part of the limiting plate 10 is still inside the slide groove 8, and the output shaft of the spring rod 9 is in a fully extended state). During this process, no intervention is required from the staff. After this step is completed, the staff can directly install the fixing bolt 20 and the fixing screw 17. The number of columns 1 connected can be controlled according to the depth of the holes.
