振动碎石桩(简称振冲桩),是在软土地基中引用振动器的水平振动,并通过高压射水钻孔,成孔后分批投入碎石逐步振密,直至设计标高。在成孔过程中,挤密了周围土体,并有大量石子嵌入周围土体中,因此桩周土体与桩身共同受力,构成复合地基,其地耐力可得到显著提高。由于施工简便,效益显著,是快速加固地基的有效办法之一。
Vibrating stone piles (referred to as vibrating piles) refer to the horizontal vibration of the vibrator in the soft soil foundation and drill holes through high-pressure water jets. After the holes are formed, the gravels are gradually injected into the vibrating rock and gradually vibrated until the design elevation is reached. In the process of pore formation, the surrounding soil is compacted and a large amount of stones are embedded in the surrounding soil. Therefore, the soil around the pile and the pile are subjected together to form a composite foundation, and its endurance can be significantly improved. Because of its simple construction and remarkable benefits, it is one of the effective ways to quickly reinforce the foundation.
