Pier column mounting method for guaranteeing thickness of base slurry of prefabricated pier column
The invention relates to a pier column mounting method capable of guaranteeing the thickness of a base slurry of a prefabricated pier column. The method comprises the following steps that a steel plate is pre-buried at the bottom of a prefabricated pier column, wherein the steel plate and the bottom surface of the prefabricated pier column are positioned on the same plane; a supporting column is arranged on a bearing platform; when the prefabricated pier column is in butt joint with the bearing platform, the top end of the supporting column is tightly attached to the prefabricated pier columnbottom embedded steel plate. And after grouting materials are laid, a crane is adopted for lowering the prefabricated pier column, the reserved steel bars of the bearing platform are inserted into theconnecting sleeves embedded in the prefabricated pier column, the center line of the bottom of the pier column is measured again in the lowering process, a jack is finely adjusted, and the prefabricated pier column is in place accurately. The method has the beneficial effects that when the pier column is lowered to a connecting mortar part, the connecting mortar located on the same plane as the supporting column cannot be squeezed away by the dead weight of the pier column, the mortar higher than the supporting column is squeezed out by the dead weight of the pier column to be evenly dispersed around the bottom of the pier column, and the plumpness of the connecting mortar is guaranteed; and the mounting quality of the pier column is effectively ensured.
本发明涉及一种保证装配式墩柱墩底座浆厚度的墩柱安装方法，包括以下步骤：在预制墩柱的底部预埋钢板，且钢板与预制墩柱底面位于同一平面；在承台上设置支撑柱；当预制墩柱与承台对接时，支撑柱的顶端与预制墩柱底部预埋钢板相紧贴；待灌浆料铺设完毕，采用吊机下放预制墩柱，通过承台预留钢筋插入预制墩柱内预埋的连接套筒，下放过程中复测墩柱底部中线，微调千斤顶，并使预制墩柱准确就位。本发明的有益效果为：可保证墩柱下放至连接砂浆部位时，与支撑柱位于同一平面的连接砂浆不会被墩柱的自重挤走，且高于支撑柱的砂浆因墩柱的自重被挤出而均匀地分散在墩柱底部四周，保证了连接砂浆的饱满性，有效地保证了墩柱的安装质量。
