Vibration high-strength composite foundation construction process
The invention relates to a vibration high-strength composite foundation construction technology, and belongs to the field of engineering construction. According to the method, hole forming is conducted through vibration construction, then uplift pile forming is conducted through grouting or powder spraying, vibration impact construction, vibration tube sinking method construction or cross wing resonance method construction can be adopted in the vibration construction, a vibration impact device is adopted in the vibration impact construction, a vibration hammer and a pile tube are adopted in the vibration tube sinking method construction, and a vibration hammer and a cross steel plate are adopted in the cross wing resonance method construction. The vibration high-strength composite foundation does not have the pile breaking phenomenon, zero-overlapping construction and liquefaction resistance can be achieved if the vibration high-strength composite foundation is broken, gravel pile water permeability is compatible, the bearing capacity is remarkably improved, the construction cost is low, and operation is easy. When the underground water quantity is sufficient, a powder spraying process is adopted; when underground water is deficient, a grouting process is adopted; and the compatibility is very good.
本发明涉及振动高强度复合地基施工工艺，属于工程施工领域。本发明采用振动施工进行造孔，之后再通过注浆或粉喷进行抗拔桩成桩，振动施工可采用振冲施工、振动沉管法施工或十字翼共振法施工，振冲施工采用振冲器，振动沉管法施工采用振动锤和桩管，十字翼共振法施工采用振动锤和十字钢板。本发明所述振动高强度复合地基不存在断桩现象，若中断可实现零重叠施工，抗液化，兼容碎石桩透水性、承载力显著提高，施工成本低、操作简单。当地下水量充分时，采用粉喷工艺；当地下水匮乏时，采用注浆工艺；兼容性非常好。
