Prefabricated energy pile and manufacturing method thereof
The invention relates to the technical field of building construction, in particular to a prefabricated energy pile for foundation pit supporting. The prefabricated energy pile comprises prestressed reinforced concrete piles, heat transfer pipes and pile plugs, wherein the prestressed reinforced concrete piles comprise non-prestressed steel bars, prestressed tendons and stirrups; the cross-sectionof the prestressed reinforced concrete piles is I-shaped, the heat transfer pipes are embedded in the prefabricated energy pile in advance, and the pile plugs are used to block a heat transfer tube entrance and a heat transfer tube exit. The invention also comprises a manufacturing method of the above prefabricated energy pile. The prefabricated energy pile provided by the invention is an I-shaped reinforced concrete pile. By adopting prestress technology, the rigidity, bending resistance and shear resistance of the pile are increased, deformation during the use of foundation pit supporting is reduced, the heat transfer piles are effectively protected, and the deformation amount of the foundation pit is greatly reduced. The invention can be prefabricated in the factory or produced on site, the prestress can be applied by pretensioning or posttensioning, and the size and reinforcement of the pile can be flexibly adjusted according to the actual project, thereby having convenient production, high efficiency, mass production and controllable quality.
本发明涉及建筑施工技术领域，尤其是一种用于基坑支护的预制能量桩，包括预应力钢筋混凝土桩、传热管和桩塞，预应力钢筋混凝土桩包括非预应力钢筋、预应力筋和箍筋，预应力钢筋混凝土桩横截面为工字型，传热管预先埋入预制能量桩中，桩塞用于封堵传热管入口和传热管出口，还包括上述预制能量桩的制作方法。本发明的预制能量桩为工字型钢筋混凝土桩，采用预应力技术，增加桩的刚度、抗弯性及抗剪性，减少在基坑支护使用过程中的变形，有效保护传热管，且大幅降低基坑变形量；既可以在工厂预制，也可以在现场生产，预应力既可以用先张法施加，也可用后张法施加，桩的尺寸和配筋可根据实际工程灵活调整，生产方便、效率高、可量产，且质量可控。
