Precast concrete pile tip and preparation method thereof
The invention discloses a precast concrete pile tip and a preparation method thereof, and belongs to the technical field of civil engineering. The precast concrete pile tip comprises concrete, a steelend plate, a pile hoop, a pile tip reinforcement cage and a hollow hole. The preparation method includes the steps of preparing a mold, preparing a vibration impactor, preparing a pile tip steel framework, putting the pile tip steel framework into the mold, pouring and vibrating concrete and carrying out curing and mold stripping. The precast concrete pile tip prepared in the invention is good inquality, high in capacity of penetrating through a hard soil layer, high in preparing efficiency and low in cost. The vibration impactor is inserted into a closed concrete filling space of the mold for preparing the precast concrete pile tip, the concrete in the space forms upward pressure, the problem that a common vibration method can not vibrate the concrete to the bottom of the steel end plate at the top of the concrete of the pile tip to be attached and compacted is solved, pile forming quality can be ensured, and engineering quality and safety are guaranteed.
一种预制混凝土桩尖及其制备方法，属于土木工程技术领域，预制混凝土桩尖包括混凝土、钢端板、桩套箍、桩尖钢筋笼以及空心洞，其方法包括制备模具、制备振动冲击器、制备桩尖钢骨架、桩尖钢骨架入模、浇筑混凝土并振捣以及养护出模。本发明制备的预制混凝土桩尖质量好、穿透坚硬土层的能力强，制备效率高、成本低；采用振动冲击器插入预制混凝土桩尖制备模具密闭的混凝土填充空间内部，使空间内的混凝土形成向上的压力，解决了常规振捣方法无法将混凝土振捣至混凝土和桩尖顶部钢端板底部紧贴密实的问题，能够确保成桩质量，保证工程质量和安全。
