The invention discloses a supporting disc type prestressed concrete pile. The supporting disc type prestressed concrete pile comprises a plurality of sections of connected pile bodies, supporting discs are arranged in the vertical direction of the pile bodies at intervals, the supporting discs protrude out of the pile bodies, the adjacent supporting disc type prestressed concrete piles are connected through pile connectors, each pile connector comprises a pile hoop and a pile end plate, and the pile end plates of the adjacent supporting disc type prestressed concrete piles are connected. According to the supporting disc type prestressed concrete pile, the supporting discs protruding out of the pile bodies are arranged between the pile bodies, the contact area of the side face of the supporting disc type prestressed concrete pile and a soil body is increased through the supporting discs, the side friction resistance of the supporting disc type prestressed concrete pile is improved, a certain end resistance can be provided, and therefore the bearing capacity of the supporting disc type prestressed concrete pile is improved, and meanwhile, the locally-protruding supporting discs can play a certain role in compacting and compacting the soil body below the supporting discs in the pile sinking process, the vertical bearing capacity of the supporting disc type prestressed concrete pile is improved, and meanwhile sedimentation of the supporting disc type prestressed concrete pile under the vertical load is reduced.
本发明公开一种支盘式预应力混凝土桩，包括若干段相连的桩身，沿桩身的竖直方向间隔设置支盘，支盘凸出于桩身设置；相邻的支盘式预应力混凝土桩之间利用桩接头相连，桩接头包括桩套箍、桩端板，相邻的支盘式预应力混凝土桩的桩端板相连。本发明在桩身之间设置了凸出于桩身的支盘，支盘增加了支盘式预应力混凝土桩侧面和土体的接触面积，提高了支盘式预应力混凝土桩的侧摩阻力，也能提供一定的端阻力，从而提高支盘式预应力混凝土桩的承载力，同时，局部凸出的支盘在沉桩过程中对支盘下的土体能够起到一定压实挤密的作用，在提高支盘式预应力混凝土桩的竖向承载能力的同时，降低了支盘式预应力混凝土桩在竖向载荷下的沉降。
