In the embodiments of the present application, a support pile is provided, and for convenience of explanation and understanding, the following description is provided on the basis of the structure of the illustrated product. Of course, those skilled in the art will appreciate that the foregoing structure is merely exemplary and illustrative and does not constitute a particular limitation on the scope of the application. In addition, the application also provides a support system.
As shown in fig. 1 to 6, the support pile 1 comprises a pile body 11 formed by concrete pouring, a plurality of prestressed steel bars 12 are penetrated in the pile body 11 along the height direction, a first counter bore 13 corresponding to the top of the prestressed steel bars 12 is arranged at the top end of the pile body 11, a second counter bore 14 corresponding to the bottom of the prestressed steel bars 12 is arranged at the bottom end of the pile body 11, a first connecting sleeve 15 connected with the prestressed steel bars 12 is arranged in the first counter bore 13, and a second connecting sleeve 16 connected with the prestressed steel bars 12 is arranged in the second counter bore 14. Specifically, the pre-stress steel bars 12 are arranged, so that the crack resistance, the rigidity and the impermeability of the support pile 1 are improved, the performance of the material can be fully exerted, and the pre-stress steel bars 12 apply compressive stress to the component concrete in advance through a pretensioning process or a post-tensioning process before the support pile 1 is used. Taking a pretensioning process as an example, before the support pile 1 is formed, the prestressed reinforcement 12 and the stirrups can be woven into a reinforcement cage, the reinforcement cage is placed into a mould, concrete materials are poured into the mould, the prestressed reinforcement 12 is tensioned through tensioning equipment, and the concrete is solidified through a plurality of processes such as centrifugation and maintenance to form the support pile 1 with the reinforcement cage connected inside. Because the prestressed reinforcement 12 applies pressure to the support pile 1, when the support pile 1 is subjected to a tensile force generated by an external load, the existing prestress in the support pile 1 is offset first, and then the support pile 1 is pulled and then cracked with the increase of the load, so that the occurrence and development of the crack of the support pile 1 are delayed. Meanwhile, after the prestressed reinforcement 12 is tensioned, the existence of the first connecting sleeve 15 and the second connecting sleeve 16 also provides guarantee for positioning of the prestressed reinforcement 12 in the pile body 11, and the prestressed reinforcement is prevented from moving along the axial direction of the pile body 11.
The first connecting sleeve 15 and the second connecting sleeve 16 can serve as intermediate pieces for connecting the tensioning device with the two ends of the prestressed reinforcement 12, so that convenience and stability of connection of the tensioning device with the prestressed reinforcement 12 are improved. In a preferred embodiment, as shown in fig. 2 and 3, the upper end surface of the first connection sleeve 15 is lower than the upper end surface of the first counterbore 13 to form a first sealing space above the first connection sleeve 15 in the first counterbore 13, the first sealing space being used for filling a sealing structure. After piling the support pile 1, the first sealing space can be filled with a sealing structure, and the sealing structure forms a protective layer on the end part of the first connecting sleeve 15, so that the first connecting sleeve 15 is isolated from the external atmospheric environment, and the first connecting sleeve 15 is prevented from being corroded by components in the external atmospheric environment. In another preferred embodiment, as shown in fig. 2 and 4, the lower end surface of the second connecting sleeve 16 is higher than the lower end surface of the second counterbore 14 to form a second sealed space below the second connecting sleeve 16 within the second counterbore 14 for filling a sealing structure. Before pile driving is performed on the support pile 1, a sealing structure can be filled in the second sealing space in advance, the sealing structure forms a protection layer on the end part of the second connecting sleeve 16, and after pile driving is performed on the support pile 1, the sealing structure isolates the second connecting sleeve 16 from groundwater and prevents components in the groundwater from corroding the second connecting sleeve 16. Therefore, after pile supporting pile 1 is constructed and piled, the existence of the sealing structures in the first sealing space and the second sealing space effectively prolongs the service lives of the first connecting sleeve 15 and the second connecting sleeve 16, greatly improves the anti-corrosion and rust-proof effects of the first connecting sleeve 15 and the second connecting sleeve 16, improves the durability of the pile supporting pile 1, and has higher engineering quality of a supporting system and long service life.
