High-penetrating-power double-tube vibration impact guide hole immersed tube pile construction technology and equipment
The invention discloses a high-penetrating-power double-pipe vibration impact guide hole immersed tube pile construction technology and equipment, and relates to the technical field of foundation treatment, the high-penetrating-power double-pipe vibration impact guide hole immersed tube pile construction technology comprises the following steps: 1) guide hole equipment is in place; (2) double-pipe hole guiding is conducted to the position about 1 m below the bottom face of the block gravel filling layer, specifically, a vibratory hammer is started, the vibratory hammer drives the inner pipe and the outer pipe to synchronously sink till the bottom of the block gravel filling layer is subjected to vibration sinking to form a hole, and then the vibratory hammer pulls out the inner pipe; (3) pipe sinking pile construction is conducted, specifically, a pile pipe is sunk into the outer pipe from the upper portion of the outer pipe, the outer pipe penetrates through soft soil layers such as block gravel filling layer guide holes and sludge till the needed depth is reached, then feeding is conducted in the pile pipe, and the pile pipe is lifted while feeding is conducted to form a dense pile body; and 4) vibrating and pulling the outer pipe and combining the inner pipe and the outer pipe. The equipment comprises a vibratory hammer, a pile gripper, an inner pipe and an outer pipe, the inner pipe is sleeved with the outer pipe to form an inner sleeve and an outer sleeve, the inner pipe and the outer pipe are fixed through the pile gripper, and the vibratory hammer is arranged at the top of the pile gripper; the device further comprises a tubular pile sinking machine. 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双管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；步骤2)双管引孔至块碎石填土层底面下约1m：开启振动锤，振动锤带动内管和外管同步下沉，振沉至块碎石填土层底成孔，随后振动锤拔出内管；步骤3)沉管桩施工：从外管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，边投料边上提桩管形成密实桩体；步骤4)振拔外管，组合内外管。设备包括振动锤、夹桩器、内管和外管，内管套设于外管内形成内外双套管，内管与外管经夹桩器固定，夹桩器顶部设有振动锤；还包括沉管桩机。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。
