碎石注浆桩技术是综合砂石桩和高压注浆两者技术逐步普及的一种新地基处理手段。因具备对施工设备要求不高、施工占地面积小、设备位置移动时灵活方便、转速高、桩体同心度较好,桩体位置偏差小等优点,以致在公路、铁路的工程施工中广泛运用。 Gravel grouting pile technology is a new foundation treatment method that integrates both gravel pile and high-pressure grouting technology gradually. Due to the requirements of construction equipment is not high, the construction area is small, the device is flexible and convenient mobile location, high speed, good pile concentricity, pile position deviation and other advantages, resulting in the highway, railway construction is widespread use.
