Steel pipe pile forming structure and steel pipe pile construction method
The invention provides a steel pipe pile forming structure and a steel pipe pile construction method.The steel pipe pile forming structure comprises a jacket arranged at the set position of a pile foundation of a riverbed or a seabed, the jacket comprises a plurality of outer sleeve steel pipes, the bottom ends of the outer sleeve steel pipes abut against a bare rock layer of the riverbed or the seabed, and a distributive girder platform is arranged at the tops of the outer sleeve steel pipes; the outer steel pipe guides the steel pipe pile, the bottom end of the steel pipe pile is inserted into a bare rock layer, and a concrete anchor pile is arranged between the bottom end of the steel pipe pile and the bare rock layer. The concrete anchor piles are arranged between the steel pipe piles and the riverbed or the seabed, the concrete anchor piles form built-in points of bed rock below the steel pipe piles, stable supporting of the steel pipe piles is ensured, the structure is easy to construct and low in construction cost, meanwhile, the concrete anchor piles are formed through one-time pouring, and the supporting strength is improved.
本发明提供了一种钢管桩成桩结构及钢管桩施工方法，包括在河床或海床的桩基设定位置处设置的导管架，导管架包括若干个外套钢管，外套钢管底端抵接于河床或海床的裸岩层，该若干个外套钢管顶部设有分配梁平台，外套钢管对钢管桩导向，钢管桩底端插至裸岩层内，在钢管桩底端和裸岩层之间设有混凝土锚桩。本发明中，在钢管桩和河床或海床间设有混凝土锚桩，混凝土锚桩在钢管桩下形成和基岩的嵌固点，确保钢管桩稳定支撑，该结构施工简单，施工成本低，同时混凝土锚桩一次浇筑形成，提高支撑强度。
