Detailed Implementation
[0026] To better illustrate the content of this utility model, the following description is provided in conjunction with the accompanying drawings and embodiments:
[0027] have Figures 1-5 As shown, this utility model discloses a solid support pile, including a pile body 1 filled with concrete 13. The pile body 1 includes a first pile segment 2, a second pile segment 3, and a third pile segment 4. A steel plate sleeve 9 is provided on the first pile segment 2 within the outer surface of the concrete 13. Two sets of pre-embedded raft slab reinforcement 14 are provided inside the steel plate sleeve 9 within the concrete 13. Each set of pre-embedded raft slab reinforcement 14 has two layers of pre-embedded raft slab reinforcement 14. Each layer of pre-embedded raft slab reinforcement 14 includes several pre-embedded raft slab reinforcement 14 evenly distributed at equal intervals. The two layers of pre-embedded raft slab reinforcement 14 are arranged perpendicular to each other.
[0028] Furthermore, the two layers of pre-embedded raft reinforcement 14 are both perpendicular to the upper, lower, front, and rear outer surfaces of the pile body 1.
[0029] Furthermore, the steel plate sleeve 9 is provided with a number of pre-embedded supporting reinforcements 7 located inside the first pile segment 2 on the side of the end plate 11 near the first pile segment 2. Each group of pre-embedded supporting reinforcements 7 includes two layers of pre-embedded supporting reinforcements 7 that are perpendicular to each other, and each layer of pre-embedded supporting reinforcements 7 includes a number of pre-embedded supporting reinforcements 7 that are evenly distributed at equal intervals.
[0030] Furthermore, both ends of the pre-embedded reinforcing bars 7 and the pre-embedded reinforcing bars 14 are fixedly connected to straight threaded sleeves 8 disposed inside the concrete 13.
[0031] In another embodiment, one layer of the pre-embedded raft slab reinforcement 14 is perpendicular to the front and rear outer sides of the pile body 1, and the other layer of the pre-embedded raft slab reinforcement 14 forms an acute angle with the upper and lower outer sides of the pile body 1.
[0032] Furthermore, both ends of the pre-embedded raft reinforcement 14 are fixedly connected with straight threaded sleeves 8 disposed inside the concrete 13.
[0033] Furthermore, the steel plate clamp 9 is penetrated by the straight threaded sleeve 8.
[0034] Furthermore, an end plate sleeve 10 located on the outer surface of the concrete 13 is also connected to the end plate 11.
[0035] Furthermore, a plurality of main reinforcement bars 12 are provided inside the pile body 1. The two ends of the main reinforcement bars 12 are connected to end plates 11. The first pile segment 2 and the third pile segment 4 located at both ends are provided with dense stirrups 5 that are penetrated by the main reinforcement bars 12. The second pile segment 3 is provided with sparsely distributed stirrups 6 that are penetrated by the main reinforcement bars 12.
[0036] Furthermore, the length of the first pile segment 2 is the height of the pile body 1 out of the pit + 2000mm.
[0037] Furthermore, before pouring the bottom slab concrete, the steel plate sleeve 9 is welded with a water-stop steel plate 15 that is parallel to the plane formed by several of the pre-embedded raft reinforcement 14.
[0038] Specifically, by pre-embedded reinforcement 7 and pre-embedded reinforcement 14 in the solid support piles, which are connected to the support reinforcement and raft reinforcement respectively, the lattice column can be directly replaced. This method is low in cost, has high bearing capacity, and does not require removing concrete from the gaps in the lattice column, making construction simple.
[0039] In addition, the pre-embedded reinforcement 7 and the pre-embedded reinforcement 14 of the raft foundation and their corresponding straight threaded sleeves 8 can be selected according to the design requirements. If the solid support pile is only used for single-layer support, it is sufficient to weld the anchor steel bars on the end plate at the top of the pile and pour them together with the support. There is no need to pre-embed reinforcement. If the solid support pile is used for multi-layer support, it is necessary to pre-embed reinforcement in the middle of the solid support pile to connect with the support steel bars and the raft foundation steel bars.
[0040] The process of pre-embedded reinforcement with straight threaded sleeves can also be replaced by pre-embedded steel pipes and then threaded steel bars through them;
[0041] In Example 2, the pre-embedded reinforcement 14 in the solid support pile is connected to the raft reinforcement, directly replacing the diagonal bracing of the lattice column.
[0042] In addition, the solid support pile of this utility model can also replace steel pipe columns or steel pipe inclined piles.
[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the technical solutions of this utility model have been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of this utility model.
