外扩式预制基础的定位方法
摘要：
本发明涉及外扩式预制基础的定位方法。外扩式预制基础的定位方法，包括如下步骤：1)、准备外扩式预制基础定位器、用于外扩式预制基础定位器的方向定位工具；2)、基坑开挖,形成基坑；3)、基础中心定位，在O点钉入中心插销；4)、安装用于外扩式预制基础定位器的方向定位工具；5)、定坑底轴线方向；6)、安装外扩式预制基础定位器：把外扩式预制基础定位器的四个定位通孔与4个边部插销对齐，边部插销插入对应的定位通孔中；测量基础底部标高，调整外扩式预制基础定位器的高度，使外扩式预制基础定位器的搁置平台的上面达到基础底面标高；7)、浇筑混凝土垫层；8)、吊装预制基础，安装完成；9)、回填素土，并碾压。能很好地使设备基础(即预制基础)定位。
摘要（英）：

The invention relates to a positioning method for an external expansion type prefabricated foundation. The positioning method for the external expansion type prefabricated foundation comprises the following steps that (1), an external expansion type prefabricated foundation positioner and a direction positioning tool for the external expansion type prefabricated foundation positioner are prepared;(2), a foundation pit is excavated and formed; (3), foundation center positioning is conducted, and a central plug pin is driven into the O point; (4), the direction positioning tool for the externalexpansion type prefabricated foundation positioner is installed; (5), the pit bottom axis direction is determined; (6), the external expansion type prefabricated foundation positioner is installed, specifically, four positioning through holes of the external expansion type prefabricated foundation positioner are aligned with four edge plug pins, the edge plug pins are inserted into the corresponding positioning through holes, the foundation bottom level is measured, the height of the external expansion type prefabricated foundation positioner is adjusted, and the upper surface of a containingplatform of the external expansion type prefabricated foundation positioner reaches the foundation bottom level; (7), a concrete cushion layer is poured; (8), the prefabricated foundation is hoisted,and installation is completed; and (9), plain soil is backfilled and ground. The equipment foundation (that is, the prefabricated foundation) can be well positioned.
