振动水冲法简称为振冲法,就是利用振动器水冲成孔,在孔内填以砂石骨料,借振冲器的水平及垂直振动振密填料,形成碎石桩体与原地基构成的复合地基,以提高地基的承载力。振动水冲法是一种快速、经济加固地基的方法。其具有节省工材、施工简单、加固期短、可因地制宜、就地取材、费用低廉等优点,是工程上广泛采用的加固地基的处理措施。但在施工过程中容易产生振冲器下沉速度过慢、石料填不下去、振冲电流过大、缩颈、断桩、加密效果差等质量问题。
The vibratory levitation method is abbreviated as vibroflotation method, which is to use water from a vibrator to punch holes, fill the holes with gravel aggregate, and vibrate the horizontal and vertical vibrating packings of the vibrator to form a gravel pile and the original foundation. The composite foundation is constructed to increase the bearing capacity of the foundation. Vibratory flooding is a fast, economical way to strengthen the foundation. It has the advantages of saving engineering materials, simple construction, short reinforcement period, local conditions, local materials, low cost, etc. It is a widely used reinforcement foundation treatment. However, during the construction process, it is easy to produce vibration problems such as slow vibration of the vibrator, failure of filling stone materials, excessive vibration current, necking, broken piles, and poor enciphering efficiency.
