High-penetrating-power double-pipe vibration immersed pipe guide hole inserting plate construction technology and equipment
The invention discloses a high-penetrating-power double-pipe vibration immersed pipe guide hole inserting plate construction technology and equipment, and relates to the technical field of foundation treatment. The construction technology comprises the steps that 1, guide hole equipment is in place; (2) the hole is led to the position about 1 m below the bottom face of the block gravel filling layer through double pipes, a vibratory hammer is started, the vibratory hammer drives the inner pipe and the outer pipe to synchronously sink and sequentially sink to the bottom of the block gravel filling layer from top to bottom to form a hole, then the vibratory hammer pulls out the inner pipe, and an outer pipe protection wall is reserved in the hole; a plastic drainage plate is inserted into the outer pipe from the upper portion of the outer pipe, the plastic drainage plate penetrates through soft soil layers such as broken stone filling layer guide holes and sludge till the needed depth is reached, and then the drainage plate is cut off; 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 sleeves 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 plate inserting machine. The method solves the problem that a deep and thick block-containing broken stone filling layer is difficult to penetrate when a guide hole inserting plate is used at present.
本发明公开了一种高穿透力双管振动沉管引孔插板施工工艺及设备，涉及地基处理技术领域，施工工艺包括：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，并自上而下依次振沉至块碎石填土层底成孔，随后振动锤拔出内管，在孔内留下外管护壁；步骤3)插板：从外管上方向其内插入塑料排水板，穿过块碎石填土层引孔、淤泥等软土层直至所需的深度，随后割去排水板；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，内管套设于外管外形成内外双套管，内管与外管经夹桩器固定，夹桩器顶部设有振动锤；还包括插板机。本发明解决了目前引孔插板时难以穿透深厚含块碎石填土层的问题。
