Prefabricated tubular pile rapid pile sinking device capable of achieving in-pipe vibration and pile periphery soil liquefaction and use method of prefabricated tubular pile rapid pile sinking device
The invention discloses a prefabricated tubular pile rapid pile sinking device for liquefying soil around a vibration pile in a pipe and a using method. The prefabricated tubular pile rapid pile sinking device comprises a pile, a supporting structure is installed at the top of the pile, a vibration liquefying device is arranged on the lower portion of the pile, a plurality of telescopic fins are arrayed on the periphery of the vibration liquefying device, and a spring is arranged at the bottom of the vibration liquefying device; a lifting device is connected between the supporting structure and the vibration liquefying device, and a plurality of sensors are arranged in the pile below the vibration liquefying device. The vibration liquefying device arranged in the tubular pile can greatly reduce the resistance of the pile end and the pile side, enables the tubular pile to rapidly pass through a soil layer, is not prone to damage a pile body, improves the success rate of one-time pile sinking, is particularly suitable for being applied to pile sinking of a dense sand foundation, meanwhile, circulates the specific process of pile lifting, soil body liquefying and static pressure pile sinking, and improves the construction efficiency. The continuous construction of the pile foundation is realized, the resistance of the pile end and the pile side in the whole construction process is reduced, and the smooth proceeding of the whole construction process is ensured; after pile sinking is completed, the vibration liquefying device can be recycled, the repeated utilization rate is high, and the engineering cost is greatly reduced; the static pressure method construction application range is widened, the advantages that static pressure method construction is low in noise and environmentally friendly are fully played, in the static pressure method construction pile sinking process, the pile pressing force can be visually, safely and accurately read out and automatically recorded, the pile bearing force control and judgment accuracy is high, a pile body is not prone to being damaged, and the pile sinking quality is high.
本发明公开了一种管内振动桩周土体液化的预制管桩快速沉桩装置及使用方法，包括桩，所述桩顶部安装有支撑结构，桩下部设有振动液化装置，所述振动液化装置四周阵列有多个可伸缩翅片，振动液化装置底部设有弹簧；所述支撑结构与振动液化装置之间连接有升降装置，所述振动液化装置下方的桩内布设有多个传感器。本发明利用管桩内置的振动液化装置，可大大减小桩端和桩侧阻力，使管桩快速地通过土层，不易损坏桩体，提高一次沉桩的成功率，尤其适合应用于密实的砂土地基沉桩，同时，将“吊桩—土体液化—静压沉桩”的特定流程进行循环操作，实现了桩基的连续施工，且减小了整个施工过程中的桩端和桩侧阻力，确保整个施工流程的顺利进行；振动液化装置在沉桩完成后，可回收再利用，可重复利用率高，工程成本大大降低；本发明拓宽了静压法施工应用范围，充分发挥了静压法施工噪音小、对环境友好的优势，且静压法施工沉桩过程中，压桩力可直观、安全、准确地读出并自动记录下来，对桩承载力控制及判断精确度高，不易损坏桩身，沉桩质量高。
