Hollow precast pile combined construction method
The invention discloses a hollow precast pile combined construction method, which comprises a force bearing mechanism assembling step, a first hollow precast pile implanting step and a subsequent hollow precast pile implanting step, specifically, the force bearing mechanism assembling step comprises a forward force bearing part protruding out of the vertical bottom end of a first hollow precast pile, and a backward force bearing part protruding out of the vertical bottom end of the second hollow precast pile; the pressure-bearing stress part protrudes out of the vertical top end of the hollow precast pile to be implanted; implanting a first hollow precast pile and implanting a subsequent hollow precast pile; the maximum outer diameter D1 of the advancing stress part is larger than the maximum outer diameter D2 of the hollow precast pile. According to the hollow precast pile, the advancing stress part is arranged and used for bearing the counter-acting force of a soil body on the hollow precast pile and reducing the impact force of the counter-acting force of the soil body on the hollow precast pile, and the pressure-bearing stress part is arranged and used for bearing the impact force applied by a pile machine, so that the phenomenon that a pile body of the hollow precast pile is damaged by the impact force applied by the pile machine is avoided; and the integrity of the hollow precast pile body is ensured.
本发明公开了一种空心预制桩组合施工方法，包括承力机构装配步骤、第一根空心预制桩植入步骤和后续空心预制桩植入步骤，承力机构装配步骤：承力机构包括凸出于第一根空心预制桩竖向底端的前进受力部，以及凸出于待植入空心预制桩竖向顶端的承压受力部；第一根空心预制桩植入步骤和后续空心预制桩植入步骤；其中，前进受力部的最大外直径D1大于空心预制桩的最大外直径D2。本发明通过设置前进受力部，前进受力部用以承受土体对空心预制桩的反作用力，削减土体反作用力对空心预制桩的冲击力，通过设置承压受力部，承压受力部用以承受桩机施加的冲击力，避免桩机施加的冲击力造成空心预制桩桩身损坏，保证空心预制桩桩身的完整性。
