The invention provides a pressure-bearing type uplift pile precast pile connecting structure and a construction method thereof. A plurality of sections of concrete pile bodies support a bearing platform, a pressure-bearing surface is arranged at a second section of a concrete pile body butted with a first section of concrete pile body connected with the bearing platform, the pressure-bearing surface is provided with a plurality of threaded sleeves, and the threaded sleeves are connected with the interior of the bearing platform through connecting ribs. The pressure-bearing surface is located on an anchoring plate, in butt joint with the first concrete pile body, of the second concrete pile body. The stress state of the connecting position of the precast pile is completely changed, tension is changed into compression, the pressure-bearing type uplift pile precast pile connecting structure has the advantages of being simple in structure, high in uplift bearing capacity, low in manufacturing cost and high in construction efficiency, and the situation that a connector is pulled and damaged due to insufficient construction quality of the connector is effectively avoided.
本发明提供了一种承压式抗拔桩预制桩连接结构及其施工方法，若干节混凝土桩体支撑承台，与承台连接的第一节混凝土桩体所对接的第二节混凝土桩体上设有承压面，所述承压面上设有若干螺纹套筒，所述螺纹套筒与承台内通过连接筋连接。所述承压面位于第二节混凝土桩体上与第一节混凝土桩体对接的锚固板上。本发明完全改变了预制桩连接处的受力状态，由受拉变为受压，具有结构简单、抗拔承载力高、造价低、施工效率高特点，有效避免了因接头施工质量不足而导致接头受拉而破坏。
