Construction technology and equipment for high-penetrating-force vibration impact guide hole immersed tube pile
The invention discloses a high-penetrating-power vibration impact guide hole immersed tube pile construction technology and equipment, and relates to the technical field of foundation treatment.The high-penetrating-power vibration impact guide hole immersed tube pile construction technology comprises the following steps that 1, guide hole equipment is in place, specifically, a vibration hammer fixes a sleeved impact tube through a fixator, and a pile frame is aligned with a pile position; (2) the impact pipe leads a hole to the position about 1 m below the bottom face of the block gravel filling layer, a vibration hammer is started, the vibration hammer drives the impact pipe to synchronously sink, vibration sinking is conducted in sequence from top to bottom till the bottom of the block gravel filling layer forms a hole, and then the vibration hammer pulls out the impact pipe; and (3) pipe sinking pile construction is conducted, specifically, a pile pipe sinks into the hole from the position above the guided hole opening, the pile pipe penetrates through the block gravel filling layer guiding hole, sludge and other soft soil layers till the needed depth is reached, then feeding is conducted in the pile pipe, and the pile pipe is vibrated and lifted up while feeding is conducted to form a dense pile body. The equipment comprises a vibratory hammer, a fixer and an impact tube, wherein the impact tube is fixed on the vibratory hammer through the fixer; the device further comprises an immersed tube pile machine and an immersed tube. The problem that a broken stone filling layer is difficult to penetrate during pipe sinking of an existing pipe sinking pile is solved.
本发明公开了一种高穿透力振动冲击引孔沉管桩施工工艺及设备，涉及地基处理技术领域，包括以下步骤：步骤1)引孔设备就位：振动锤经固定器固定好套设的冲击管，桩架对准桩位；步骤2)冲击管引孔至块碎石填土层底面下约1m：开启振动锤，振动锤带动冲击管同步下沉，自上而下依次振沉至块碎石填土层底成孔，随后振动锤拔出冲击管；步骤3)沉管桩施工：从已引孔孔口上方向其内沉入桩管，穿过块碎石填土层引孔、淤泥等软土层直至所需的深度，接着向桩管内投料，边投料边振动上提桩管形成密实桩体。设备包括振动锤、固定器、冲击管，冲击管经固定器固定于振动锤上；还包括沉管桩机与沉管。本发明解决了目前沉管桩沉管时难以穿透块碎石填土层的问题。
