Pulse hydraulic static pressure pile machine construction process method
The invention discloses a construction process method of a pulse hydraulic static pressure pile machine. The construction process method comprises the following steps that S1, early-stage preparation of construction is conducted, a pile machine is in place, and a pile body is detected; s2, the piles are hoisted and inserted; s3, static pressure pile sinking; s4, hammering and sinking the pile; s5, high-frequency vibration pile sinking; s6, recording and transferring the pile machine; after pile lifting and inserting in the S2 are completed, static-pressure pile sinking is conducted, four small supporting leg oil cylinders are installed at the two ends of two long boats of a static pile driver correspondingly, and the self weight of equipment is jacked and stretched and falls according to the frequency; the four-corner oil cylinders are started, the equipment is jacked upwards by 0.1 m, the oil cylinders relieve pressure at the same time, the equipment freely falls, gravitational potential energy of the equipment is converted into kinetic energy to act on the pipe pile, and continuous pile sinking is achieved; and the jacking and stretching height is kept unchanged, the jacking and stretching frequency is increased and adjusted to 10 HZ to 15 HZ, and pile sinking continues to be kept. According to the invention, the impulse of the pile body is improved, the construction characteristics and advantages of the static press, the hammering pile and the high-frequency vibration pile forming are integrated, and the construction efficiency and the penetrating power are greatly improved.
本发明公开了一种脉冲液压式静压桩机施工工艺工法，施工工法步骤如下：S1：施工前期准备，桩机就位以及桩体检测；S2：吊桩插桩；S3：静压沉桩；S4：锤击沉桩；S5：高频振动沉桩；S6：记录、转移桩机；基于S2中的吊桩插桩完成后，进行静压沉桩，在静力压桩机的两个长船两端分别安装四个小支腿油缸，将设备自重按照频率顶伸和下坠；启动四角油缸，将设备顶伸向上高度0.1m，油缸同时泄压，设备自由落体，将设备重力势能转化为动能作用于管桩，实现继续沉桩；保持顶伸高度不变，将顶伸频率加大，顶伸频率调整至10HZ‑15HZ，继续保持沉桩。本发明提高了桩体的冲量，综合了静压机、锤击桩、高频振动成桩施工特点优势，施工效率及穿透能力上有较大改善。
