Construction method of concrete-filled steel tube pile foundation and concrete-filled steel tube pile foundation
The invention relates to a construction method of a concrete-filled steel tube pile foundation and the concrete-filled steel tube pile foundation. The construction method comprises the steps that a steel tube pile is placed at a preset position of a river bed surface, and the steel tube pile is inserted downwards from the top of the steel tube pile until the steel tube pile cannot sink; impact pore forming is conducted in the steel tube pile; the steel tube pile continues to be inserted until the steel tube pile cannot sink; impact pore forming and insertion of the steel tube pile are conducted alternately until the bottom end of the steel tube pile reaches the designed depth; and concrete is poured into the steel tube pile. According to the construction method of the concrete-filled steel tube pile foundation and the concrete-filled steel tube pile foundation, under the condition of complex geology, the steel tube pile can be smoothly inserted into soil for pile sinking, the bearing capacity of the concrete-filled steel tube pile foundation is good, and the friction pile stress requirement and the end bearing pile stress condition can be met.
本发明涉及一种钢管混凝土桩基的施工方法及钢管混凝土桩基，其包括：在河床面的预设位置放置钢管桩，并于所述钢管桩的顶部向下插打所述钢管桩至无法下沉；在所述钢管桩的内部冲击造孔；继续插打所述钢管桩至无法下沉；冲击造孔与插打所述钢管桩交替进行，直至所述钢管桩底端到达设计深度；在所述钢管桩内灌注混凝土。本发明涉及的一种钢管混凝土桩基的施工方法及钢管混凝土桩基，在复杂地质的情况，钢管桩也能顺利入土沉桩，且钢管混凝土桩基的承载力较好，能够达到摩擦桩受力要求和端承桩受力条件。
