Construction measurement method for mounting large prefabricated abutment on sea
The invention relates to a construction measurement method for mounting a large prefabricated abutment on the sea, a low abutment sequentially comprises a bearing platform, a lower-section pier body, an upper-section pier body and a cover beam from bottom to top, a high abutment sequentially comprises a bearing platform, a lower-section pier body, a middle-section pier body, an upper-section pier body and a cover beam from bottom to top, and the construction measurement method comprises the following steps: detecting a prefabricated abutment finished product; measuring control point positions are marked on prefabricated abutments; the perpendicularity of the prefabricated abutment is controlled; performing deviation control on the prefabricated abutment; mounting an inclination sensor; and accurately adjusting, positioning and controlling measurement. According to the control method, measurement is controlled through repeated measurement, hoisting pre-positioning and accurate positioning of the prefabricated abutment finished product, the plane position, the elevation and the perpendicularity of the prefabricated abutment after installation meet the design and specification requirements, and the control method can provide reference for similar engineering construction.
本发明是一种大型预制墩台海上安装的施工测量方法，低墩台由下到上依次包括承台、下节墩身、上节墩身及盖梁，高墩台由下到上依次包括承台、下节墩身、中节墩身、上节墩身及盖梁，包括以下步骤：预制墩台成品检测；预制墩台标记测量控制点位；预制墩台垂直度控制；预制墩台偏位控制；倾斜传感器安装；精调定位控制测量。本发明通过预制墩台成品复测、吊装预定位和精确定位控制测量，预制墩台安装后的平面位置、高程、垂直度满足设计及规范要求，其控制方法可以为类似工程施工提供借鉴。
