Pore-forming construction method for old bridge pile site in-situ percussion drill matched with rotary drilling rig
The invention discloses a pore-forming construction method for an old bridge pile site in-situ percussion drill matched with a rotary drilling rig. The construction method comprises the following steps: step 1, leveling a site; step 2, setting out a pile position; step 3, burying a pile casing; Step 4, percussion drilling in place; step 5, centering inspection; step 6, slurry preparation and circulation; and step 7, percussion drilling; Step 8, lifting the percussion drill; and step 9, secondarily re-measuring the pile casing. The percussion drill is matched with the rotary drilling rig for drilling construction, the advantages of combination of the two devices are exerted, when a newly-built bridge pile foundation coincides with or conflicts with an old bridge pile foundation, the percussion drill is used for constructing the old pile foundation part, the rotary drilling rig is used for rapidly forming holes below the old pile foundation, the construction sequence is clear, and construction is safe and reliable; The unit price cost of percussion drill construction is much higher than that of rotary drilling rig construction, part of drilling construction cost is saved on the premise that the rotary drilling rig is adopted for hole forming of the part below the old pile foundation, the equipment cost is obviously saved, and the construction efficiency is high.
本发明公开了老桥桩位原址冲击钻配合旋挖钻成孔施工工法，包括以下步骤；步骤一、平整场地，步骤二、桩位放样，步骤三、埋设护筒；步骤四、冲击钻就位，步骤五、对中检查，步骤六、泥浆制备与循环，步骤七、冲击钻进；步骤八、冲击钻提钻，步骤九、二次复测护筒。本发明采用冲击钻配合旋挖钻钻孔施工，发挥两种设备组合的优势，新建桥梁桩基与老桥桩基重合或冲突时，冲击钻施工老桩基部分，老桩基以下采用旋挖钻机迅速成孔，施工顺序明晰，施工安全可靠，冲击钻施工单价费用比旋挖钻机施工单价费用高很多，老桩基以下部分采用旋挖钻机成孔在保证质量和安全的前提下节约部分钻孔施工费用，设备成本节约明显，施工效率高。
