Construction method for hammering, ramming, leading hole drilling and construction of steel pipe pile
The invention relates to a construction method for hammering, ramming, guiding and drilling a hole in a steel pipe pile. The construction method comprises the following steps: vertically fixing the steel pipe pile at a designed position; a steel wire rope of a crawler crane penetrates through the steel pipe end protection base and is connected with an impact heavy hammer through a percussion drill steel wire rope connector, then the impact heavy hammer is placed in the steel pipe pile, and the steel pipe end protection base falls to the upper end of the steel pipe pile and is clamped; the impact heavy hammer and the vibration hammer sequentially and circularly sink the steel pipe pile until the ballasts generated by tamping influence the tamping efficiency; a slurry box is connected with the steel pipe pile, a hole is formed in the upper portion of the joint of the steel pipe pile and the slurry box, high-pressure slurry is poured into the steel pipe pile, and the slurry drives rock ballast to flow into the slurry box through the hole; after no rock ballast flows out, the slurry box is dismantled, and the open hole is blocked; and the third step to the fifth step are repeated till the steel pipe piles penetrate through the riprap layer or the rock layer. The construction process is simple and convenient, a large amount of concrete, steel pipe piles, steel pile casings and filling materials are not needed, and the construction cost can be effectively reduced.
本申请涉及钢管桩锤夯引孔打设施工方法，包括如下步骤将钢管桩竖直固定于设计位置；将履带吊机的钢丝绳穿过钢管端部防护座，通过冲击钻机钢丝绳连接头与冲击重锤连接，随后将冲击重锤放置于钢管桩内并将钢管端部防护座下落于钢管桩上部端头并卡紧；冲击重锤和振动锤依次循环下沉钢管桩，直至夯击产生的石渣影响夯击效率；将泥浆箱与钢管桩连接，并在钢管桩与泥浆箱连接处上方开孔，向钢管桩内冲入高压泥浆，使泥浆带动石渣通过开孔流入泥浆箱内；待无石渣流出后，拆除泥浆箱并封堵开孔；重复步骤三至步骤五，直至钢管桩穿透抛石层或穿入岩石层。本发明施工工序简单、便捷，不需要大量的混凝土、钢管桩、钢护筒和填充材料，能够有效降低施工成本。
